    Congenital hemangiomas are rare solitary vascular tumors that do not proliferate after birth. They are characterized as either rapidly involuting congenital hemangiomas (RICHs) or noninvoluting congenital hemangiomas (NICHs) based on their clinical progression. NICHs have no associated complications, but are persistent. RICH, while usually asymptomatic, may ulcerate or bleed early in their presentation, but involute quickly during the first few months of life. Hepatic RICHs are not associated with cutaneous RICHs, but may result in high-output cardiac failure due to arteriovenous or portovenous shunting. In the following review, the clinical characteristics and current management specific to congenital hemangiomas is discussed. PMID:27607320

    Context: Intramuscular hemangiomas are common in the general population and often present at medical and surgical clinics. Unfortunately, unfamiliarity with these lesions has led to a high percentage of misdiagnoses, inappropriate workup, and unnecessary referrals. Evidence Acquisition: A literature search was performed using Medline, Embase, PubMed, and Cochrane. The relevant articles and referenced sources were reviewed for additional articles that discussed the epidemiology, pathophysiology, investigation, and management of intramuscular hemangiomas. Clinical experience from experts in orthopaedics, musculoskeletal pathology, and musculoskeletal radiology was compared. The selected case studies are shared cases of the authors. Results and Conclusion: The pathophysiology of these lesions is not completely understood, but much can be implied from their underlying vascular nature. Isolated lesions are benign tumors that never metastasize but tend to enlarge and then involute over time. Magnetic resonance imaging is the imaging modality of choice. If a systemic disorder or malignancy is not suspected or has been ruled out, conservative management is the treatment of choice for most intramuscular hemangiomas. PMID:24427416

    Hemangiomas are the most common soft tissue tumors of infancy. Almost 60% of these tumors develop in the head and neck region. Nasal hemangiomas, distort human physiognomy and leave long lasting psychological sequelae. Conservative approach (intralesional corticosteroids, laser) may accelerate involution. Proponents of an early surgery suggest that aesthetic improvement during a critical period in child development can be achieved. Fourteen patients with nasal hemangioma were treated during 5-year period (2003-2007) with intralesional corticosteroids, lenticular excision, open rhinoplasty excision, and circular excision with "purse string suture". The first line of treatment for large nasal hemangiomas is intralesional corticosteroids. Excision is indicated for small hemangiomas, while subtotal excision is preferable for large nasal hemangiomas. Circular excision and "purse string suture" is appropriate for prominent hemangiomas with predominant deep component. In our opinion surgery with maximal care for nasal architecture is the treatment option for nasal hemangioma. PMID:19656579

She might have had an excessive craving for strawberries, witnessed the slaughter of an animal, directly contacted human or animal blood, or mocked a child with a similar birthmark.1 This folklore began to slowly fade once hemangiomas were examined through the light microscope. In 1863, Virchow2 suggested that hemangiomas are composed of proliferating new blood vessels resulting from progressive irritation of tissue. In 1933, Laidlow and Murray3 proposed a phylogenetic origin for hemangiomas and hypothesized that hemangiomas are remnants of vascular tufts functioning as accessory lungs for primitive amphibia. Pack and Miller4 (1950) hypothesized that hemangiomas develop from embryonic islands of angioblastic cells that were isolated from the systemic vasculature during fetal development. PMID:22881413

    2015-01-01

    Hepatic hemangiomas are benign tumors of the liver consisting of clusters of blood-filled cavities, lined by endothelial cells, fed by the hepatic artery. The vast majority of HH are asymptomatic, most often being discovered incidentally during imaging investigations for various unrelated pathologies. Typical hemangiomas, the so-called capillary hemangiomas, range from a few mm to 3 cm, do not increase in size over time and therefore are unlikely to generate future symptomatology. Small (mm-3 cm) and medium (3 cm-10 cm) hemangiomas are well-defined lesions, requiring no active treatment beside regular follow-ups. However, the so-called giant liver hemangiomas, of up to 10 cm (most commonly) and even 20+ cm in size (according to occasional reports) can, and usually will develop symptoms and complications that require prompt surgical intervention or other kind of therapy. HH belong to the class of hepatic “incidentalomas”, so-called because they are diagnosed incidentally, on imaging studies performed as routine examinations or for other reasons than the evaluation of a possible liver mass. Less than half of HH present with overt clinical symptoms, consisting, most often, of upper abdominal pain (this is usually the case for large lesions, which cause the distension of Glisson’s capsule). Hepatic hemangiomas require a careful diagnosis to differentiate from other focal hepatic lesions, co-occurring diagnoses are also possible. PMID:26361504

    Circumscribed choroidal hemangiomas are benign vascular hamartomas without systemic associations. Generally, they are orange-red elevated masses, which are found posterior to the equator. Lesions are usually solitary and unilateral. Overlying subretinal fluid, serous retinal detachment and cystoid macular edema are common findings. Intravenous fluorescein angiography, indocyanine green angiography, ultrasonography, optical coherence tomography and enhanced depth imaging are helpful ancillary tests for diagnosis of circumscribed choroidal hemangiomas. Asymptomatic circumscribed choroidal hemangiomas do not require treatment. For symptomatic lesions with exudative retinal detachment or cystoid macular edema, photodynamic therapy has emerged as the treatment of choice with high rates of tumor regression, subretinal fluid resorption and minimal complications. Lens-sparing external beam radiotherapy, plaque brachytherapy, proton beam therapy, stereotactic radiosurgery, transpupillary thermotherapy, laser photocoagulation and anti-VEGF injections are other treatment modalities.

    Targetoid Hemosiderotic Hemangioma, also known as Hobnail Hemangioma, is a lesion of vascular origin, probably lymphatic. The most common clinical feature is a solitary violaceous papule surrounded by a pale, thin area and a peripheral ecchymotic ring, simulating a target. Histopathologically, there is a biphasic pattern, with dilated vessels in the superficial dermis and pseudoangiosarcomatous pattern in the deep dermis, and endothelial cells with hobnail morphology. A simple excision is curative. We report a rare case of Targetoid Hemosiderotic Hemangioma. PMID:25387500

    Patient: Male, 81 Final Diagnosis: Sclerosed hemangioma Symptoms: — Medication: — Clinical Procedure: Autopsy Specialty: Diagnostics, Laboratory Objective: Rare disease Background: A sclerosed hemangioma of the liver, an extremely rare type of benign hepatic tumor, was found at autopsy. Case Report: An 81-year-old Japanese man was admitted to our hospital for surgical resection of squamous cell carcinoma of the skin in his left forearm. At admission, serological tests for hepatitis B surface antigen and hepatitis C antibody were negative with no evidence of cirrhosis. At 2, 3, and 5 months after the removal of the forearm tumor, skin grafting was performed because of unhealed skin ulceration. Although anti-bacterial drugs were prescribed, the patient died after the 3rd skin graft (5 months after the surgery) because of pneumonia. During the treatment course, the patient was diagnosed as having multiple liver masses suspected to be cysts of the liver based on non-contrasted computed tomography results. Autopsy revealed a sclerosed hemangioma occupying the entire left lobe accompanied by multiple small cavernous hemangiomas in the right lobe of the liver. Conclusions: Sclerosed hemangioma, a rare benign disease, occurred in association with degeneration and sclerosis of cavernous hemangiomas of the liver. The VEGF pathway may be involved in the genesis of cavernous and sclerosed hemangioma of the liver. PMID:26116763

    Infantile hemangiomas as frequent infancy tumors have been a controversial issue of medical scientists worldwide. Their clinical aspects are various and their physiopathology is yet to be fully understood. Numerous publications outline the characteristics, causes, evolution possibilities and therapeutic approaches. Deciding whether to treat or not is the main question of this kind of pathology. Hemangiomas that have complications or can cause irreversible damage need therapy. This is a brief review of up-to-date information regarding the presentation of infantile hemangiomas and target-therapies. PMID:26528043

    2014-01-01

    Infantile hemangioma is a common tumor of infancy. Although most hemangiomas spontaneously regress, treatment is indicated based on complications, risk to organ development and function, and disfigurement. The serendipitous discovery of propranolol, a non-selective β-adrenergic receptor blocker, as an effective means to regress hemangiomas has made this a first-line therapy for hemangioma patients. Propranolol has shown remarkable response rates. There are, however, some adverse effects, which include changes in sleep, acrocyanosis, hypotension, and hypoglycemia. Over the last few years, researchers have focused on understanding the mechanisms by which propranolol causes hemangioma regression. This has entailed study of cultured vascular endothelial cells including endothelial cells isolated from hemangioma patients. In this article, we review recent studies offering potential mechanisms of how various cell types found in hemangioma may respond to propranolol. PMID:26413184

    Compared with the imaging features of typical hepatic hemangiomas, the imaging features of atypical hepatic hemangiomas have not been well studied or well described. Knowledge of the entire spectrum of atypical hepatic hemangiomas is important and can help one avoid most diagnostic errors. A frequent type of atypical hepatic hemangioma is a lesion with an echoic border at ultrasonography. Less frequent types are large, heterogeneous hemangiomas; rapidly filling hemangiomas; calcified hemangiomas; hyalinized hemangiomas; cystic or multilocular hemangiomas; hemangiomas with fluid-fluid levels; and pedunculated hemangiomas. Adjacent abnormalities consist of arterial-portal venous shunt, capsular retraction, and surrounding nodular hyperplasia; hemangiomas can also develop in cases of fatty liver infiltration. Associated lesions include multiple hemangiomas, hemangiomatosis, focal nodular hyperplasia, and angiosarcoma. Types of atypical evolution are hemangiomas enlarging over time and hemangiomas appearing during pregnancy. Complications consist of inflammation, Kasabach-Merritt syndrome, intratumoral hemorrhage, hemoperitoneum, volvulus, and compression of adjacent structures. In some cases, such as large heterogeneous hemangiomas, calcified hemangiomas, pedunculated hemangiomas, or hemangiomas developing in diffuse fatty liver, a specific diagnosis can be established with imaging, especially magnetic resonance imaging. However, in other atypical cases, the diagnosis will remain uncertain at imaging, and these cases will require histopathologic examination. PMID:10715338

    Infantile hemangioma (IH), the most common tumor of infancy, is characterized by an initial proliferation during infancy followed by spontaneous involution over the next 5–10 years, often leaving a fibro-fatty residuum. IH is traditionally considered a tumor of the microvasculature. However, recent data show the critical role of stem cells in the biology of IH with emerging evidence suggesting an embryonic developmental anomaly due to aberrant proliferation and differentiation of a hemogenic endothelium with a neural crest phenotype that possesses the capacity for endothelial, hematopoietic, mesenchymal, and neuronal differentiation. Current evidence suggests a putative placental chorionic mesenchymal core cell embolic origin of IH during the first trimester. This review outlines the emerging role of stem cells and their interplay with the cytokine niche that promotes a post-natal environment conducive for vasculogenesis involving VEGFR-2 and its ligand VEGF-A and the IGF-2 ligand in promoting cellular proliferation, and the TRAIL-OPG anti-apoptotic pathway in preventing cellular apoptosis in IH. The discovery of the role of the renin–angiotensin system in the biology of IH provides a plausible explanation for the programed biologic behavior and the β-blocker-induced accelerated involution of this enigmatic condition. This crucially involves the vasoactive peptide, angiotensin II, that promotes cellular proliferation in IH predominantly via its action on the ATIIR2 isoform. The role of the RAS in the biology of IH is further supported by the effect of captopril, an ACE inhibitor, in inducing accelerated involution of IH. The discovery of the critical role of RAS in IH represents a novel and fascinating paradigm shift in the understanding of human development, IH, and other tumors in general. PMID:25593962

    Hemangioma of the facial nerve may occur more frequently than previously recognized. This benign vascular tumor most often arises in the area of the geniculate ganglion, although the reason for this site of predilection is not known. Using silicon injection and cross-sectional vessel counts, we recently demonstrated the presence of a geniculate capillary plexus (GCP) in the cat. The present study was designed to identify a similar GCP in man, if present, and to relate if to the site of predilection of hemangioma of the facial nerve. Twenty-five human facial nerves were studied in horizontally sectioned temporal bones. A clinical case of hemangioma arising at the geniculate ganglion is presented. The human geniculate ganglion has a very rich capillary plexus in contrast to the poor intrinsic vasculature of the adjacent labyrinthine segment and nioderate vasculature of the tympanic segment of the facial nerve. We hypothesize that the GCP is the origin of most hemangiomas of facial nerve. The anatomic distinctness of the geniculate gangion and GCP from the facial nerve may allow removal of these tumors with preservation of motor function in certain cases.

    Hemangioma is the most common vascular tumor of infancy; presentation is often as cutaneous infantile hemangioma (IH). Cutaneous hemangioma is a clinical diagnosis. Most IHs follow a benign course, with complete involution without treatment in the majority of cases. Visceral hemangioma often involves the liver and manifests as a life-threatening disorder. Hepatic hemangiomas may be associated with high output cardiac failure, coagulopathy, and hepatomegaly which generally develop between 1 and 16 weeks of age. Mortality has been reportedly high without treatment. We report a rare case of a male infant with neonatal hemangiomatosis with diffuse peritoneal involvement, which mimicked a malignant-looking tumor on imaging, and discuss therapeutic options and efficacy. Propranolol is efficacious for IH but generally not useful for other forms of vascular hemangiomas, tumors, and malformations. In our case of neonatal peritoneal hemangiomatosis, propranolol appears to have halted the growth and possibly expedite the involution of the hemangiomatosis without other treatments. PMID:27110421

    Verrucous hemangioma is a rare vascular malformation consisting of a proliferation of dilated blood vessels of different sizes that occupy the dermis and hypodermis. The epidermis of the affected area shows a strong proliferative reaction that presents as a warty appearance. Here, we report the case of a 17-year-old male who presented with an asymptomatic warty growth above the lateral malleolus on the right leg, which healed after electrocautery. PMID:27462218

    Liver hemangiomas are the most common benign liver tumors and are usually incidental findings. Liver hemangiomas are readily demonstrated by abdominal ultrasonography, computed tomography or magnetic resonance imaging. Giant liver hemangiomas are defined by a diameter larger than 5 cm. In patients with a giant liver hemangioma, observation is justified in the absence of symptoms. Surgical resection is indicated in patients with abdominal (mechanical) complaints or complications, or when diagnosis remains inconclusive. Enucleation is the preferred surgical method, according to existing literature and our own experience. Spontaneous or traumatic rupture of a giant hepatic hemangioma is rare, however, the mortality rate is high (36-39%). An uncommon complication of a giant hemangioma is disseminated intravascular coagulation (Kasabach-Merritt syndrome); intervention is then required. Herein, the authors provide a literature update of the current evidence concerning the management of giant hepatic hemangiomas. In addition, the authors assessed treatment strategies and outcomes in a series of patients with giant liver hemangiomas managed in our department. PMID:23445235

    Vascular tumors of childhood are typically benign. The 4 most common types are infantile hemangioma (IH), congenital hemangioma (CH), kaposiform hemangioendothelioma (KHE), and pyogenic granuloma (PG). Vascular tumors must be differentiated from vascular malformations. Although tumors and malformations may appear as raised, blue, red, or purple lesions, their management differs significantly.

    A capillary-cavernous hemangioma in an obturator lymph node was found incidentally in a 64 year-old woman who had undergone unilateral salpingo-oophorectomy and lymphadenectomy for an ovarian neoplasm. Vascular tumors of lymph nodes are briefly reviewed including eight previously described nodal capillary-cavernous hemangiomas. The association with other splanchnic hemangiomas is pointed out and the likelihood that the lesion is a hamartoma rather than a true neoplasm is addressed. Despite its rarity, this entity needs to be recognized by lymphologists who image lymph nodes by lymphangiography as well as by lymph nodal pathologists. PMID:10494525

    Liver tumors seldom occur in the perinatal period. Hepatic hemangiomas are the most common tumors of the liver diagnosed during fetal and neonatal life. The diagnosis can be suspected antenatally by ultrasound and MR scan. The differential diagnosis is often challenging. While small hepatic hemangiomas are usually asymptomatic, large tumors can lead to complications such as high-output congestive heart failure, consumptive thrombocytopenic coagulopathy and hemorrhage after tumor rupture. We describe a case of hepatic hemangioma presenting as a solid abdominal mass with several cystic areas on an obstetric ultrasound and report on the contribition fetal MR imaging to the diagnosis.

    Lipomas and hemangiomas are well-known benign lesions of the body. However, their occurrence in the oral cavity is rare. Lipoma accounts for 1-4% of benign neoplasms of mouth affecting predominantly the buccal mucosa, floor of mouth and tongue. Hemangiomas occur mostly on the lips, buccal mucosa, tongue, and palate. Lipomas when superficially placed show yellowish surface discoloration and hemangiomas usually have reddish blue to deep blue color. Here, we report an unusual case of benign tumor occurring in the buccal vestibule. PMID:26097370

    Background: Capillary hemangiomas are neoplasms involving skin and soft tissue in infants. These lesions rarely involved an intracranial space and reported age distribution ranges from infancy to middle age. We report an extremely rare case of rapidly rising intracranial capillary hemangioma in an elderly woman. Case Description: The 82-year-old woman presented with vomiting, reduced level of consciousness, and worsening mental state. Computed tomography showed a contrast-enhanced extra-axial lesion in the left frontal operculum, although no intracranial mass lesion was identifiable from magnetic resonance imaging taken 2 years earlier. Complete surgical excision was performed and histopathological examination diagnosed benign capillary hemangioma consisting of a variety of dilated capillary blood vessels lined by endothelial cells. Conclusion: This is the first description of rapid growth of an intracranial capillary hemangioma in an elderly woman. These lesions are exceedingly rare in the elderly population, but still show the capacity for rapid growth. Complete excision would prevent further recurrence. PMID:26664868

    The treatment effects of 7 cases of choroid hemangioma are reported. Of them, 4 cases were men and 3 cases were women. Ages varied from 34 to 52 years. The mean age was 43 years. All of their eyesight was between 0.01 and 0.4. Six of the seven cases were solitary hemangioma, the other one was Sturge-Weber syndrome. After treatment photography, the color of the hemangioma body gradually got weak and the local presented pigmentation. The results of the fluorescein fundus angiography indicated that the hemangioma body reduced, then got atrophy and fibrosis. In five cases eyesight increased, and it didn't in the other two cases.

    Hemangiosarcomas are uncommon aggressive vascular tumors that have recently become the focus of attention because several chemicals and pharmaceuticals increase their incidence in mice. The relevance of these mouse vascular tumors to humans is unclear. In the present study, we semiquantitatively evaluated the expression profiles of hematopoietic stem cell markers (CD117 [c-kit], CD133, CD34, and CD45), endothelial cell markers (vascular endothelial growth factor receptor 2, CD31, and factor VIII-related antigen), and a myeloid lineage cell marker (CD14) in human hemangiosarcoma (n = 12) and hemangioma (n = 10) specimens using immunohistochemistry. CD133 was completely negative in almost all cases of hemangiosarcomas and hemangiomas. Most hemangiosarcomas, but not hemangiomas, stained for CD117 and CD45. Both groups diffusely expressed CD34, vascular endothelial growth factor receptor 2, and factor VIII-related antigen; however, hemangiomas had more intense and diffuse CD34 and factor VIII-related antigen expression compared with hemangiosarcomas, whereas CD31 was positive in all hemangiosarcomas but only half of the hemangiomas. CD14 staining was negative in most hemangiosarcoma and hemangioma cases. Our results indicate that multipotential bone marrow-derived hematopoietic stem cells or early endothelial progenitor cells (EPCs) expressing CD117, CD34, and CD45 are involved in hemangiosarcoma formation, whereas hemangiomas originate from late EPCs or differentiated endothelial cells, which have lost the expression of most hematopoietic stem cell markers. This contrasts with our previous results that demonstrated that both hemangiosarcomas and hemangiomas in mice may be derived from early EPCs that are not completely differentiated. PMID:24054722

    Infantile hemangiomas (IHs) are the most common vascular tumors of infancy. While the majority regress without the need for intervention, approximately 10%, often site dependent, can cause serious complications and require treatment. IH complications can be categorized as life threatening, obstructive, ulcerative or disfiguring. Life threatening complications include airway and hepatic IHs. Functional complications obstructing vital structures or impairing function include periocular, nasal, labial, parotid, auricular, and breast IHs. Local complications arise from ulceration or those in cosmetically sensitive areas. Therapeutic options for complicated IHs include pharmacologic (topical or systemic), surgical, or laser interventions. Topical agents are best employed for small, superficial, and localized IHs; while systemic therapy is reserved for larger IHs and those with more aggressive growth characteristics with propranolol as first-line therapy.

    Patient: Male, 34 Final Diagnosis: Intramuscular hemangioma of the masseter muscle Symptoms: Swelling over parotid region Medication: — Clinical Procedure: Clinical-Radiological work-up Specialty: Radiology Objective: Rare disease Background: Hemangioma is a benign vascular proliferation. Intramuscular hemangiomas are rare, accounting for less than 1% of all hemangiomas, and occur normally in the trunk and extremities. Approximately 10–20% of intramuscular hemangiomas are found in the head and neck region, most often in the masseter muscles. The typical clinical characteristic is a painful soft tissue mass without cutaneous changes. Currently, MRI is the standard imaging technique for diagnosing soft-tissue hemangioma. The optimal management is the surgical resection. Case Report: We report a case of 34-year-old male patient consulted for a swelling of 1 year evolution, around the parotid region. On physical examination, a soft, well-contoured lesion of about 2 cm on its long axis was found. MRI showed a space-occupying lesion in the left masseter muscle, with intermediate signal intensity on T1-weighted images and hyperignal intensity on T2-weighted images, containing nodular hypointense foci corresponding to calcification. The presumptive diagnosis of an intramasseteric hemangioma with phlebolith was made based on these findings. The patient was informed about her condition, and treatment options were discussed; however, the patient elected to forgo treatment at that time. Conclusions: The possibility of an IMH should be included in the differential diagnosis of any intra-masseteric lesion. The appropriate radiologic examinations especially MRI can enhance accurate preoperative diagnosis; the treatment of choice should be individualized in view of the clinical status of the patient.

    Hemangiomas are known to be common benign tumors. However, hemangiomas of female genital organs are very rare. Furthermore, a retroperitoneal hemangioma arising from ovarian vessels has never been reported. Here we report a case of a 29-year-old woman with a retroperitoneal cavernous hemangioma arising from the ovarian vessels of infundibulopelvic ligament, which was treated with laparoscopic resection. The operating time was 30 minutes, and resection was carried out with minimal blood loss. The postoperative period was uneventful, and the patient was discharged on postoperative day 3. Laparoscopic resection of this type of hemangioma is feasible. PMID:19896610

    Many practitioners assume every vascular lesion is a hemangioma; then tell parents not to worry, because hemangiomas "go away" after they grow. In fact, over the past three decades, advances in the stratification of vascular lesions, identification of clinical associations and syndromic vascular anomalies, and the discovery of germline and somatic mutations accompanying certain vascular anomalies have broadened our understanding. Concomitantly, the evaluation and management of vascular anomalies have become more sophisticated, and a laissez-faire approach is often inadequate. This paper focuses on hemangiomas of infancy and is divided into two sections, Evaluation and Management, both sections including updated references to clinical and basic research and reviews supporting the discussion.

    Background: Capillary hemangioma is a rare tumor in spinal intradural location. Despite the rarity, early recognition is important because of the risk of hemorrhage. This is a case report of a woman who had capillary hemangioma of cauda equina. Case Description: A 54 -year-old woman presented with a low backache, radiating to the left leg for 2 months. She had left extensor hallucis weakness, sensory impairment in left L5 dermatome, and mild tenderness in lower lumbar spine. Magnetic resonance imaging (MRI) LS spine showed L4/5 intradural tumor, completely occluding canal in myelogram, enhancing with contrast, s/o benign nerve sheath tumor. L4 laminectomy was done. Reddish tumor was seen originating from a single root. It was removed preserving the root. Postoperatively, she was relieved of symptoms. MRI showed no residue. Histopathology showed lobular proliferation of capillary-sized blood vessels and elongated spindle cells. Immunohistochemistry showed CD34 positivity in endothelial cell lining of blood vessel and smooth muscle actin positivity in blood vessel muscle cells. HPR-capillary hemangioma. Conclusion: Although rare, capillary hemangioma should be in the differential diagnosis of intradural tumors. It closely mimics nerve sheath tumor. PMID:27069745

    Hemangiomas are benign vascular tumors. They are the prerogative of the liver and skin. And genitourinary localizations are rare and have only been rarely reported in the prostat, bladder, ureter or the perineum. In the light of published cases, urethral hemangiomas are mostly found in males. Few cases of hemangioma in the female urethra were reported. We report a cavernous hemangioma of the urethra in a 61 years old patient who presented bleeding from the urethra and micturition disorders. Physical examination revealed a tumor 3 cm x 2 polyploid arising from the terminal urethra (urethral hemangioma). We performed surgical resection of the tumor, along with bladder drainage. The postoperative course was simple. We update through a review of the literature aspects of the diagnostic and therapeutic care of the urethral hemangioma. PMID:27231506

    A 39-year-old female with a large cavernous hemangioma of the liver was successfully treated by ligation of the left hepatic artery. A wedge biopsy specimen of the hemangioma was obtained after the ligation and was examined by scanning electron microscopy. The hemangioma was demarcated from the surrounding normal liver parenchyma and had a labyrinth of caves 50-150 microns in diameter. The caves were separated by fibrous septa 20-40 microns in width. Endothelial cells of the caves were spindle-shaped and arranged in parallel. The surface property of the caves resembled that of the hepatic artery and differed from that of the portal vein or hepatic vein. These findings support that the cavernous hemangioma of the liver was supplied by the hepatic artery. The labyrinthine structure of the cavernous hemangioma may explain the long standing contrast enhancement of the hemangioma after hepatic arteriography. PMID:6832546

    OBJECTIVE Vertebral hemangiomas are common tumors that are benign and generally asymptomatic. Occasionally these lesions can exhibit aggressive features such as bony expansion and erosion into the epidural space resulting in neurological symptoms. Surgery is often recommended in these cases, especially if symptoms are severe or rapidly progressive. Some surgeons perform decompression alone, others perform gross-total resection, while others perform en bloc resection. Radiation, embolization, vertebroplasty, and ethanol injection have also been used in combination with surgery. Despite the variety of available treatment options, the optimal management strategy is unclear because aggressive vertebral hemangiomas are uncommon lesions, making it difficult to perform large trials. For this reason, the authors chose instead to report their institutional experience along with a comprehensive review of the literature. METHODS A departmental database was searched for patients with a pathological diagnosis of "hemangioma" between 2008 and 2015. Medical records were reviewed to identify patients with aggressive vertebral hemangiomas, and these cases were reviewed in detail. RESULTS Five patients were identified who underwent surgery for treatment of aggressive vertebral hemangiomas during the specified time period. There were 2 lumbar and 3 thoracic lesions. One patient underwent en bloc spondylectomy, 2 patients had piecemeal gross-total resection, and the remaining 2 had subtotal tumor resection. Intraoperative vertebroplasty was used in 3 cases to augment the anterior column or to obliterate residual tumor. Adjuvant radiation was used in 1 case where there was residual tumor as well. The patient who underwent en bloc spondylectomy experienced several postoperative complications requiring additional medical care and reoperation. At an average follow-up of 31 months (range 3-65 months), no patient had any recurrence of disease and all were clinically asymptomatic, except the

    Hemangiomas and vascular malformations of the gastrointestinal tract, rare clinical entities, present as overt or occult bleeding. They can be distributed throughout the intestinal digestive system, or present as a singular cavernous hemangioma or malformation, which is often located in the rectosigmoid region. Misdiagnosis is common despite characteristic radiographic features such as radiolucent phleboliths on plain film imaging and a purplish nodule on endoscopy. Adjunctive imaging such as computed tomography and magnetic resonance imaging are suggested as there is potential for local invasion. Endorectal ultrasound with Doppler has also been found to be useful in some instances. Surgical resection is the mainstay of treatment, with an emphasis on sphincter preservation. Nonsurgical endoscopic treatment with banding and sclerotherapy has been reported with success, especially in instances where an extensive resection is not feasible. PMID:22942801

    Cardiac hemangiomas are rare primary tumors of the heart and constitute only 2.8% of primary cardiac tumors. They are classified into capillary, cavernous, epitheloid and arteriovenous type and the last one is the most uncommon type. We experienced a case of cardiac hemangioma which was diagnosed as arteriovenous type for the first time in Korea in the literature. The patient was a 54-year-old woman who presented with palpitation and anterior chest pain. The diagnosis was based upon coronary angiography which showed two tumor blushings located in the interatrial and interventricular septum with venous drainage to the coronary sinus and right atrium. Associated atrial fibrillation with rapid ventricular response was controlled with digitalis. PMID:9735668

    Despite the fact that a biological classification of congenital vascular tumors and malformations was first published in 1982 by Mulliken and Glowacki, significant confusion still prevails due to the indiscriminate and interchangeable use of the terms hemangioma and vascular malformation. Hemangiomas are true neoplasms of endothelial cells and should be differentiated from vascular malformations which are localized defects of vascular morphogenesis. On an analysis of various scientific articles and latest edition of medical text books an inappropriate use of various terms for vascular lesions was found, contributing further towards the confusion. The widely accepted International Society for the Study of Vascular Anomalies (ISSVA) classification differentiates lesions with proliferative endothelium from lesions with structural anomalies and has been very helpful in standardizing the terminologies. In addition to overcoming obstacles in communication when describing a vascular lesion, it is important that we adhere to the correct terminology, as the therapeutic guidelines, management and follow-up of these lesions differ.

    We report two cases of epithelioid hemangioma (EH) manifested in the thoracic spine with associated clinical, radiographic, and pathological findings. Epithelioid hemangioma is a benign vascular tumor that can involve any bone (including the spine in a subset of patients). Although recognized as a benign tumor by the WHO, it can display locally aggressive features. Within the spine, these features may lead to pain, instability, and/or neurologic dysfunction. The radiographic appearance is most typically that of a lytic, well-defined lesion on plain film or CT. The MRI appearance is typically hypointense on T1WI, hyperintense on T2WI, and avidly enhancing, often with an extraosseous soft-tissue component.

    Hemangiomas are benign vascular tumors of childhood that can lead to disfigurement and/or life-threatening consequences. The pathogenesis of hemangioma formation is likely to involve increased angiogenesis. Basic fibroblast growth factor and vascular endothelial growth factor are cytokines that stimulate angiogenesis in multiple in vivo and in vitro models. Proliferative hemangiomas have been found to have elevated levels of basic fibroblast growth factor and vascular endothelial growth factor protein, but the gene expression of these cytokines in human specimens has not been previously studied. We examined the gene expression and spatial distribution of basic fibroblast growth factor and vascular endothelial growth factor messenger RNA in proliferative versus involuted human hemangioma specimens using nonisotopic in situ hybridization techniques. Thirteen hemangioma specimens were harvested during initial surgical excision. In situ hybridization was performed on frozen sections of both proliferative and involuted hemangioma specimens using genetically engineered antisense probes specific for basic fibroblast growth factor and vascular endothelial growth factor messenger RNA. Controls were an interleukin-6 sense sequence and a transforming growth factor-beta 1 antisense sequence. A large number of cells within the specimens of proliferative hemangiomas revealed localized gene expression of basic fibroblast growth factor and vascular endothelial growth factor messenger RNA (626 +/- 129 and 1660 +/- 371 cells/mm2, respectively). The majority of the cells were endothelial in origin. In contrast, involuted hemangioma specimens revealed significantly lower numbers of cells staining positive for basic fibroblast growth factor and vascular endothelial growth factor messenger RNA (44 +/- 11 and 431 +/- 76 cells/mm2, respectively; p < 0.05). Transforming growth factor-beta 1 messenger RNA was slightly more expressed by involuted hemangiomas (117 +/- 30 cells/mm2). There

Through standard radiological and vascular procedures it was defined as being of hepatic origin, vascular etiology and of benign prognosis. Differences among cavernous hemangioma, hepatoma, metastasis and hemangio-endothelioma are summarized. The importance of angiography is emphasized as an essential procedure previous to the surgical evaluation and therapy. PMID:566065

    Hepatic hemangiomas are congenital vascular malformations, considered the most common benign mesenchymal hepatic tumors, composed of masses of blood vessels that are atypical or irregular in arrangement and size. Hepatic hemangiomas can be divided into two major groups: capillary hemangiomas and cavernous hemangiomas These tumors most frequently affect females (80%) and adults in their fourth and fifth decades of life. Most cases are asymptomatic although a few patients may present with a wide variety of clinical symptoms, with spontaneous or traumatic rupture being the most severe complication. In cases of spontaneous rupture, clinical manifestations consist of sudden abdominal pain, and anemia secondary to a haemoperitoneum. Disseminated intravascular coagulopathy can also occur. Haemodynamic instability and signs of hypovolemic shock appear in about one third of cases. As the size of the hemangioma increases, so does the chance of rupture. Imaging studies used in the diagnosis of hepatic hemangiomas include ultrasonography, dynamic contrast-enchanced computed tomography scanning, magnetic resonance imaging, hepatic arteriography, digital subtraction angiography, and nuclear medicine studies. In most cases hepatic hemangiomas are asymptomatic and should be followed up by means of periodic radiological examination. Surgery should be restricted to specific situations. Absolute indications for surgery are spontaneous or traumatic rupture with hemoperitoneum, intratumoral bleeding and consumptive coagulopathy (Kassabach-Merrit syndrome). In a patient presenting with acute abdominal pain due to unknown abdominal disease, spontaneous rupture of a hepatic tumor such as a hemangioma should be considered as a rare differential diagnosis.

    Infantile hemangioma is the consequence of both postnatal vasculogenesis and angiogenesis. Hypoxia appears to play an important role as a contributory factor. Infantile hemangiomas have variable clinical features: superficial, deep or mixed. They can be localized or segmental involving a large skin area. Localized infantile hemangiomas are usually benign, unless they are located near a noble structure (airway orbit...), while segmental infantile hemangioma may be associated with complex underlying birth defects (PHACES and SACRAL syndromes). Clinical follow-up of infants with infantile hemangioma must be particularly careful in the first weeks of life since 80% of all infantile hemangiomas have reached their final size at age 5 months. A majority of infantile hemangiomas are mild and do not required any treatment. Main indications for treatment are: vital risk (heart failure, respiratory distress), functional risk (amblyopia, swallowing disorders...), painful ulceration and disfigurement (face involvement of nose, lips...). Propranolol, has been quickly adopted as the first line medical treatment for complicated infantile hemangioma; and it is the only treatment to have a marketing authorization in this indication. It is recommended to begin the treatment as early as possible before three months of age to minimize the risk of complications and sequelae. PMID:25665327

    Intramuscular hemangioma, an infrequent but important cause of musculoskeletal pain, is often difficult to establish the diagnosis clinically. This report describes a case of a 32-yr-old woman who presented with severe left calf pain for 10 yr. Initial conservative treatments consisting of intramuscular electrical stimulation, herb medication, acupuncture, and intramuscular lidocaine injection under the diagnosis of myofascial pain syndrome in other facilities, failed to alleviate the symptoms. On physical examination, there was no motor weakness or sensory change. Conventional radiography of the leg revealed a soft tissue phlebolith. Conventional angiography study showed hemangioma. Intramuscular hemangioma within the soleus muscle was confirmed by magnetic resonance imaging. Following surgical excision of the hemangioma, the patient's symptom resolved completely. Intramuscular hemangioma is a rare cause of calf pain and should be considered in the differential diagnosis if a patient with muscle pain, particularly if associated with a soft tissue mass, fails to respond to conservative treatment.

    Summary Painful vertebral body hemangiomas have been successfully treated with vertebroplasty and kyphoplasty. Sacral hemangiomas are uncommon and as such painful sacral hemangiomas are rare entities. We report what we believe is only the second successful treatment of a painful sacral hemangioma with CT-guided sacroplasty. A 56-year-old woman with a history of right-sided total hip arthroplasty and lipoma excision presented to her orthopedic surgeon with persistent right-sided low back pain which radiated into her buttock and right groin and hindered her ability to walk and perform her activities of daily living. MRIs of the thoracic spine, lumbar spine and pelvis showed numerous lesions with imaging characteristics consistent with multiple hemangiomas including a 2.2×2.1 cm lesion involving the right sacrum adjacent to the right S1 neural foramen. Conservative measures including rest, physical therapy, oral analgesics and right-sided sacroiliac joint steroid injection did not provide significant relief. Given her lack of improvement and the fact that her pain localized to the right sacrum, the patient underwent CT-guided sacroplasty for treatment of a painful right sacral hemangioma. Under CT fluoroscopic guidance, a 10 gauge introducer needle was advanced through the soft tissues of the back to the margin of the lesion. Biopsy was then performed and after appropriate preparation, cement was then introduced through the needle using a separate cement filler cannula. Appropriate filling of the right sacral hemangioma was visualized using intermittent CT fluoroscopy. After injection of approximately 2.5 cc of cement, it was felt that there was near complete filling of the right sacral hemangioma. With satisfactory achievement of cement filling, the procedure was terminated. Pathology from biopsy taken at the time of the procedure was consistent with hemangioma. Image-guided sacroplasty with well-defined endpoints is an effective, minimally invasive and safe

    Introduction Hepatic and splenic hemangiomas are common benign tumors that mainly affect female patients. Giant splenic hemangiomas are extremely rare, especially when correlated with multiple hepatic hemangiomas. Pathogenetic mechanisms between hemangiomas and oral contraceptives, as well as therapeutic approaches, are analyzed in this case report, in particular for the management of synchronous splenic and hepatic hemangiomas. Case presentation We report here a 42-year-old woman with a giant splenic hemangioma, multiple hepatic hemangiomas and a history of oral estrogen intake for many years. At first it was difficult to determine the organ from which the giant hemangioma originated. Angiography proved extremely helpful in tracing its origin in the spleen. Hematomas in the giant hemangioma posed a significant threat of rupture and catastrophic hemorrhage. We left the small hepatic hemangiomas in place, and removed the spleen along with the giant splenic hemangioma. Conclusion Diagnostic pitfalls in the determination of the origin of this giant hemangioma, attribution of its origin to the spleen angiographically, the unusual co-existence of the giant splenic hemangioma with multiple hepatic ones, and the potential threat of rupture of the giant hemangioma are some of the highlights of this case report. Estrogen administration represents a pathogenic factor that has been associated with hemangiomas in solid organs of the abdominal cavity. The therapeutic dilemma between resection and embolization of giant hemangiomas is another point of discussion in this case report. Splenectomy for the giant splenic hemangioma eliminates the risk of rupture and malignant degeneration, whereas observation for the small hepatic ones (<4 cm) was the preferable therapeutic strategy in our patient.

    Hemangiomas account for 0.4-0.6% of all tumors of the parotid gland and most of them occur in children, nevertheless in adults hemangiomas are very rare. We report the case of a 62 year old woman with a mass in the parotid right tail associated with fluctuating swelling episodes unrelated to meals and with a slowly progressive growth. The provisional diagnosis was a pleomorphic adenoma, so a right superficial parotidectomy was performed. During surgery, the macroscopic appearance makes suspect a vascular lesion. The histopathological result was a cavernous hemangioma. The classic clinical presentation of a parotid hemangioma is an intraglandular mass associated or not with skin lesions characterized by reddish macules and/or papules, and a vibration or pulsation when palpating the parotid region. In imaging tests, phleboliths could be observed which are very suggestive of a hemangioma or a vascular malformation. In the absence of these signs, the diagnosis could be difficult, particularly in an adult due to its low prevalence, with about 50 cases reported worldwide. However a hemangioma should be considered in the differential diagnosis of parotid tumors in adults. Key words:Cavernous hemangioma, parotid gland, superficial parotidectomy, pleomorphic adenoma.

    Primary intraosseous cavernous hemangiomas (PICHs) are benign vascular tumors that may involve any part of the body. PICH occurs more frequently in the spine and less commonly in skull. The earliest description in the English literature was in 1845 by Toynbee, who reported a vascular tumor arising in the confines of the parietal bone. Skull PICHs do not always have typical radiologic features and should always be considered in the differential diagnosis of malignant skull lesions. We now reviewed and analyzed related literatures in detail with reporting a rare case of PICH in the left front bone that was surgically resected. PMID:26986133

    The sensitivity, specificity and predictive values of dynamic CAT with contrast piston-stroke performed at a single cut are described for the diagnosis of hepatic hemangiomas. We analyzed the correlation between the findings obtained through dynamic CAT and those obtained through echography, PAAF, analytic and clinical study of the patients with suspicion of hepatic hemangioma. The following values were obtained: sensitivity 92.3%; specificity 50%; VPP 88.8%; VPN 60%; and global diagnostic affectivity 84.37%. According to these results, we think that dynamic CAT is a highly reliable test for the diagnosis of hepatic hemangiomas. PMID:7772685

    The authors report one case of cavernous hemangioma of the left ovary, which was revealed by ovarian torsion. Such benign tumors of the blood vessels are rare in ovaries during childhood. This hemangioma was observed in a 13-year-old patient, who presented with abdominal and pelvic pain and vomiting. The pelvic mass was noted and sonography revealed a cystic tumor. An annexectomia was realized. Histology showed narcotized ovary cells, with an increased number of vascular channels composed of thin walled vessels, whose wall consisted of an endothelium. This aspect evoked a cavernous hemangioma of the ovary. PMID:14613693

    Sclerosing hemangioma of the lung is a benign neoplasm with a widely debated histogenesis. It has a polymorphic histomorphology characterized by a biphasic cell population of “surface cells” and “round cells” arranged in four general patterns: Papillary, solid, angiomatous, and sclerotic. This variability in histomorphology makes it difficult to diagnose sclerosing hemangioma by fine needle aspiration (FNA). We present a case of sclerosing hemangioma diagnosed on FNA with immunohistochemistry performed on an accompanied cell block. The clinical presentation, cytomorphology, immunohistochemistry, and differential diagnoses are discussed. PMID:27168758

    A 62-year-old female presented with a pelvic mass and ascites. The Papanicolaou vaginal smear showed an unusual maturation, maturation index being 0/80/20. The serum level of estradiol was 48.7 pg/ml. The preoperative checkup suggested a pelvic malignancy with a differential diagnosis of hormone-secreting ovarian tumor. On surgical exploration, she had a hemangioma of the ovary without malignant cytology in the ascitic fluid. Histologically, this tumor was associated with stromal luteinization. This is the first case, reported in the literature, possessing ovarian hemangioma with stromal luteinization accompanying massive ascites. It should be noted that an ovarian hemangioma can be associated with stromal luteinization and ascites, and that MR imaging is sometimes of value for making a preoperative diagnosis of ovarian hemangioma.

    Hemangioma is the most common type of benign tumor that arises in the liver. Although rupture and hemorrhage of hepatic hemangioma are rare complications, they can be the cause of mortality. The authors report a case of hemorrhagic hepatic hemangioma: in a 54-year-old woman who was admitted with epigastric pain. She had taken oral contraceptives several weeks prior. The results of a blood examination were normal. An abdominal computed tomography scan revealed a tumor in hepatic segment 4, and a hemorrhage inside the cystic mass was suspected. The mass was removed laparoscopically to confirm the tumor properties and control the hemorrhage. The pathologic findings of the resected mass were consistent with hepatic hemangioma with intratumoral hemorrhage. The patient was discharged 8 d after the surgery, without further complications or complaints, and the patient’s condition was found to have improved during follow-up. PMID:26109822

    Hemangioma of the heart is a rare primary benign tumor mainly appearing as enhancing, homogenous, well-circumscribed mass. We report a case of a 61-year-old asymptomatic woman, whose echocardiography showed a cardiac mass, which was described as the atypical myxoma of the right atrium. For further imaging, contrast-enhanced computed tomography and cardiac magnetic resonance imaging were undertaken, which showed a tumor located in the interatrial septum with imaging characteristics of hemangioma. In the literature, cardiac hemangioma is usually described as an intensely enhancing mass. In our opinion, early peripheral puddling of contrast material with filling in on delayed images is a typical pattern of its enhancement. This characteristic, in addition to high signal intensity on T2-weighted images, allows differentiation of a hemangioma from other benign and malignant tumors.

    A laser is disclosed for directing a nominally 5 micron wavelength beam at a hemangioma or other variegated lesion. A fiber optic bundle for intercepting radiation reflected from the lesion at an intensity corresponding with the color intensity of the region at which the beam is directed. The output beam from the fiber optic bundle modulates a photodetector stage whose amplified output drives a galvanometer. The galvanometer shaft is coupled to the shaft of a potentiometer which is adjustable to regulate the laser power supply and, hence, the laser output energy level so laser beam energy is reduced when high absorption regions in the lesion are being scanned by the beam and increased as low absorption regions are being scanned.

    Infantile hemangiomas (IHs) are the most common tumors of childhood. Unlike other tumors, they have the unique ability to involute after proliferation, often leading primary care providers to assume they will resolve without intervention or consequence. Unfortunately, a subset of IHs rapidly develop complications, resulting in pain, functional impairment, or permanent disfigurement. As a result, the primary clinician has the task of determining which lesions require early consultation with a specialist. Although several recent reviews have been published, this clinical report is the first based on input from individuals representing the many specialties involved in the treatment of IH. Its purpose is to update the pediatric community regarding recent discoveries in IH pathogenesis, treatment, and clinical associations and to provide a basis for clinical decision-making in the management of IH.

    Epithelioid hemangioma (EH) and Kimura's disease (KD) were once considered different stages of the same disease, as they share many clinical and histopathologic similarities. Nowadays, they are considered as two different entities, but some authors still confuse these terms. Our objective is to present a case of EH occurring in a very uncommon location and to emphasize the microscopic and clinical differences between EH and KD. We present a case of EH of the orbit in an 83-year-old man diagnosed after histopathologic evaluation of a mass that was surgically removed from the orbit. The tumor showed typical microscopic appearance with pathognomonic epithelioid endothelial cells. The diagnosis was also confirmed by immunohistochemical analysis. Our case clearly illustrates typical appearance of EH and the main differences between EH and KD are thoroughly discussed. PMID:26058249

    Background Anastomosing hemangioma (AH) of the kidney is a recently described morphological variant of hemangioma. It poses a diagnostic dilemma for clinicians because of its rarity and the overlapping features it shares with other renal vascular tumors. The aim of this paper is to review all the cases of AH of the kidney in the literature. Methods The literature was extensively searched for case reports of AH of the kidney and the clinical and pathological characteristics of the tumor were extracted. Results A total of 45 cases were reviewed. The mean age of presentation was 50 years (range, 15-83 years) and male sex accounted for 68.8% of the cases reviewed. AH of the kidney was mostly unilateral with only 4 cases of bilateral involvement of the kidney. The average size of the tumor is 1.5 cm (range, 0.1-7 cm). Incidental finding of AH of the kidney accounted for 62% of the cases reviewed. The ultrasound findings demonstrated varying echogenicity and the tumor appeared as solid and well demarcated heterogeneous masses on CT. The average follow up of the patients in this review was 26 months (range, 1-156 months). Conclusions AH of the kidney is a rare vascular tumor and a morphological variant of hemangioma. It has a characteristic sinusoidal architecture with a semblance of splenic sinusoids. It has overlapping clinical and imaging features with other vascular tumors of the kidney. Histological review and immunohistochemical studies are essential for accurate diagnosis. AH runs a benign course without evidence of disease recurrence during follow up. PMID:26244138

    The authors report on colon cancer metastasis to the L-3 vertebra, which had been previously found to be involved by an asymptomatic hemangioma. A 61-year-old female patient was admitted after onset of lumbar axial pain and weakness of the right quadriceps muscle. Her medical history included colon cancer that had been diagnosed 3 years earlier and was treated via a right hemicolectomy followed by chemotherapy. Presurgical imaging revealed an asymptomatic hemangioma in the L-3 vertebral body. Computed tomography and MRI of the spine were performed after admission and revealed a hemangioma in the L-3 vertebral body as well as a soft-tissue mass protruding from the L-3 vertebral body to the spinal canal. Treatment consisted of vertebroplasty of the hemangioma, left L-3 hemilaminectomy, and removal of the pathological mass from the spinal canal and the L-3 vertebral body. Histopathological examination revealed the presence of colon cancer metastasis and a hemangioma in the same vertebra. PMID:26588498

    A retroperitoneal hemangioma is a rare disease. We report on the diagnosis and treatment of a retroperitoneal hemangioma which had uncommonly invaded into both the pancreas and duodenum, thus requiring a pylorus preserving pancreaticoduodenectomy (PpPD). A 36-year-old man presented to our hospital with abdominal pain. An enhanced computed tomography scan without contrast enhancement revealed a 12 cm × 9 cm mass between the pancreas head and right kidney. Given the high rate of malignancy associated with retroperitoneal tumors, surgical resection was performed. Intraoperatively, the tumor was inseparable from both the duodenum and pancreas and PpPD was performed due to the invasive behavior. Although malignancy was suspected, pathological diagnosis identified the tumor as a retroperitoneal cavernous hemangioma for which surgical resection was the proper diagnostic and therapeutic procedure. Reteoperitoneal cavernous hemangioma is unique in that it is typically separated from the surrounding organs. However, clinicians need to be aware of the possibility of a case, such as this, which has invaded into the surrounding organs despite its benign etiology. From this case, we recommend that combined resection of inseparable organs should be performed if the mass has invaded into other tissues due to the hazardous nature of local recurrence. In summary, this report is the first to describe a case of retroperitoneal hemangioma that had uniquely invaded into surrounding organs and was treated with PpPD. PMID:23901241

    The cavernous hemangioma is the most common benign orbital tumor in adults. Its presentation is during the forth to fifth decades with a slowly progressive unilateral proptosis. Intraconal cavernous hemangiomas may be difficult to differentiate from other intraconal lesions such as schwannomas, meningiomas and hemangiopericytomas. We report a case of orbital cavernous hemangioma diagnosed by Tc-99m RBC scintigraphy. Tc-99m RBC scintigraphy revealed a typical scintigraphic pattern in which there is intense focally increased uptake on the delayed image. We conclude that Tc-99m RBC scintigraphy can be a useful method in the differential diagnosis of orbital cavernous hemangioma as in hepatic hemangioma. PMID:11448074

    Hemangiomas are the most common masses of the major salivary glands in parotid glands in childhood particularly. They occur more frequently in the parotid gland and rarely the submandibular gland. Changes in blood flow dynamics within hemangiomas may induce thrombus formation and phleboliths. Cavernous hemangioma may lead to thrombophlebitis in major salivary glands in adults. To our knowledge, cavernous hemangioma of submandibular glands containing phleboliths in childhood has not been described so far in the literature. In this article, we report the first pediatric case of a cavernous hemangioma containing multiple phleboliths in the submandibular gland mimicking submandibular sialolithiasis in a seven-year-old boy.

    Abstract Bronchial‐pulmonary arterial fistula (BPAF) is a rare vascular malformation complicated with racemose hemangioma. We report a case of a 65‐year‐old male with BPAF with primary racemose hemangioma. Bronchial arteriography demonstrated convolution, dilation, and aneurysm connected with pulmonary artery, suggesting the presence of BPAF, in the left upper lobe. Since a 20‐mm sized aneurysm of bronchial artery and BPAF coexisted, he underwent ligation of bronchial arterial aneurysm and left upper lobectomy to prevent hemoptysis. As neither history of prior illness nor histopathologic findings of vascular inflammation was seen, the present case demonstrated BPAF with primary racemose hemangioma. Establishment of non‐invasive treatment strategy for BPAF is urgently required. PMID:27081488

    Hemangiomas of the median nerve are very rare and, so far, only ten cases of intraneural hemangioma of this nerve have been reported in the literature. We present a case of 14-year-old girl who had a soft tissue mass in the region of the left wrist with signs and symptoms of carpal tunnel syndrome. Total removal of the mass was achieved using microsurgical epineural and interfasicular dissection. The symptoms were relieved completely, after this procedure, without any neurologic deficit. On follow-up two years later, no recurrence was observed. Whenever a child or young adult patient presents with CTS the possibility of a hemangioma involving the median nerve should be kept in mind in the differential diagnosis. PMID:18294368

    Adrenal hemangioma is an extremely rare benign and non-functioning neoplasm of the adrenal gland. We report a case of a 71-year-old woman admitted for intermittent abdominal pain and abdominal distension associated with vomiting and chronic constipation for 5 years. Physical examination revealed a large abdominal mass. Both computed tomography scan and magnetic resonance imaging suggested hemangioma in the right lobe of the liver. Laboratory examinations and tumour markers were within normal limits, except for hypochromic microcytic anemia. The mass was removed intact by conventional surgery and histopathology revealed a cavernous hemangioma of the adrenal gland with no signs of malignancy. Surgical resection was curative, with no recurrence at the 2-year follow-up. PMID:26600897

    Introduction Pregnancy-related compressive myelopathy secondary to vertebral hemangioma is a rare occurrence and its treatment antepartum is rare. Case presentation A 19-year-old North African woman in her 38th week of pregnancy presented with paraplegia that progressed within 2 days after a rapidly progressive weakness of her lower limbs. Magnetic resonance imaging studies showed compression of her spinal cord in front of the fourth thoracic vertebra for suspected tuberculous spondylitis. A Caesarean section was done followed by corpectomy with a bone graft because we intraoperatively discovered a vertebral hemangioma. Pathology showed an aggressive hemangioma. Conclusion At any term of pregnancy, extensive neurological involvement which is rapidly progressive due to compression should be considered for immediate decompression. PMID:24943121

    Purpose: Patients with choroidal hemangioma (CH), a benign ocular hamartoma, frequently presents with visual disturbance as a result of exudative retinal detachment (RD), which originates in subretinal fluid accumulation. We report our experience using the Leksell Gamma Knife in the management of symptomatic CH. Methods and Materials: Seven patients with symptomatic CH (circumscribed form in 3 patients and diffuse form in 4) were treated with the Leksell Gamma Knife at our institution during a 7-year period. All patients presented with exudative RD involving the macula that resulted in severe visual deterioration. The prescription dose to the target margin was 10 Gy in all cases. The mean tumor volume receiving the prescription dose was 536 mm{sup 3} (range, 151-1,057). The clinical data were analyzed in a retrospective fashion after a mean follow-up of 34.4 months (range, 9-76). Results: The resolution of exudative RD was achieved within 6 months, and the visual acuity of the affected eye had improved at the latest follow-up examination (p = .018) in all patients. No recurrence of exudative RD occurred. Thinning of the CHs was observed in most patients; however, symptomatic radiation toxicity had not developed in any of the patients. Conclusion: Symptomatic CHs can be safely and effectively managed with Gamma Knife radiosurgery using a marginal dose of 10 Gy.

    CT or MRI are utilized in the initial evaluation of adrenal incidentalomas; however, overlap exists between benign and malignant lesions on these examinations. The American College of Radiology recommends PET scans to complement CT and MRI for patients with adrenal masses and a moderate-to-high likelihood of neoplastic disease. We present images of a PET-avid adrenal lesion in a patient with pulmonary and pancreatic neoplasms that mimicked metastasis, but was found to be a benign adrenal hemangioma on surgical resection. The use of PET for adrenal tumors, specifically adrenal hemangiomas, will be reviewed. PMID:24089061

    Background Infantile hemangiomas are the most common tumor of infancy, yet there are no FDA-approved therapeutics to date. Recently, the non-selective beta-adrenergic-blocker propranolol has been shown to be a safe and effective means of treating infantile hemangiomas, though its mechanism has yet to be elucidated. We have previously demonstrated that propranolol induces early and incomplete adipogenesis in stem cells derived from hemangiomas. We hypothesize that propranolol promotes dysregulated adipogenesis via the improper regulation of adipogenic genes. Methods Hemangioma stem cells isolated from resected infantile hemangioma specimens were treated with adipogenic medium for 1 or 4 days in either propranolol or vehicle. Cell death was measured by the incorporation of annexin V and propidium iodide by flow cytometry. Adipogenesis was assessed by visualizing lipid droplet formation by Oil Red O staining. Pro-adipogenic genes C/EBPβ, C/EBPβ, C/EBPδ, PPARδ, PPARγ, RXRα, and RXRγ were analyzed by quantitative reverse transcription and polymerase chain reaction. Results Hemangioma stem cells treated with propranolol increased lipid droplet formation compared to vehicle-treated cells indicating increased adipogenesis. Cell death as measured by FACS analysis indicated that the propranolol-treated cells died due to necrosis and not apoptosis. During adipogenesis, transcript levels of PPARδ, PPARγ, C/EBPβ, and C/EBPδ were significantly increased (p < 0.01) in propranolol-treated cells relative to control cells. In contrast, RXRα and RXRγ levels were significantly decreased (p < 0.05), and C/EBPα, a gene required for terminal adipocyte differentiation, was strongly suppressed by propranolol when compared to vehicle-treated cells (p < 0.01). Conclusions In hemangioma stem cells, propranolol accelerated dysregulated adipogenic differentiation characterized by improper adipogenic gene expression. Consistent with accelerated adipogenesis, propranolol

    2009-01-01

    Although unusual, hemangioma is the most common primary splenic neoplasm. Splenectomy is indicated when the tumor is large, with increased risk of hemorrhage. The laparoscopic approach is preferred for most elective splenectomies. Although technically feasible, laparoscopic splenectomy can be a challenge in the patient with splenomegaly. We present herein a case of an 18-year-old male asymptomatic patient who underwent laparoscopic splenectomy for the incidental finding of splenomegaly caused by a large splenic hemangioma. Laparoscopic splenectomy appears to be a safe and effective procedure, in appropriately experienced hands, for patients with splenomegaly, given the spleen's fragile anatomy and its relationship to other abdominal viscera.

    The hemangioma of the adrenal gland is an adrenal gland lesion rare, benign and usually asymptomatic. Discovered incidentally during an abdominal imaging study, it is part of incidentalomas. Imagery is the best to characterise these silent adrenal masses (computed tomography [CT], Magnetic Resonance Imaging [MRI]± Positron Emission Tomography [PET scan] with 18F-FDG). The main risks of the hemangioma are ignorance of malignancy, bleeding and abdominal mass syndrome. The analysis of the literature shows the importance of laparoscopy. A multidisciplinary discussion on this type of lesion appears indispensable both diagnostic and therapeutic. PMID:22118362

    Vertebral hemangiomas (VHs) are a frequent and often incidental finding on computed tomography (CT) and magnetic resonance (MR) imaging of the spine. When their imaging appearance is "typical" (coarsened vertical trabeculae on radiographic and CT images, hyperintensity on T1- and T2-weighted MR images), the radiological diagnosis is straightforward. Nonetheless, VHs might also display an "atypical" appearance on MR imaging because of their histological features (amount of fat, vessels, and interstitial edema). Although the majority of VHs are asymptomatic and quiescent lesions, they can exhibit active behaviors, including growing quickly, extending beyond the vertebral body, and invading the paravertebral and/or epidural space with possible compression of the spinal cord and/or nerve roots ("aggressive" VHs). These "atypical" and "aggressive" VHs are a radiological challenge since they can mimic primary bony malignancies or metastases. CT plays a central role in the workup of atypical VHs, being the most appropriate imaging modality to highlight the polka-dot appearance that is representative of them. When aggressive VHs are suspected, both CT and MR are needed. MR is the best imaging modality to characterize the epidural and/or soft-tissue component, helping in the differential diagnosis. Angiography is a useful imaging adjunct for evaluating and even treating aggressive VHs. The primary objectives of this review article are to summarize the clinical, pathological, and imaging features of VHs, as well as the treatment options, and to provide a practical guide for the differential diagnosis, focusing on the rationale assessment of the findings from radiography, CT, and MR imaging.

    2011-01-01

    Background Different types of vascular proliferation may occur in lymph nodes, but hemangiomas in lymph nodes are extremely rare. Case Presentation A 73-year-old man was found to have a 15-mm nodular shadow in the left lung on computed tomography, and bronchoscopic brush cytology yielded a diagnosis of squamous cell carcinoma. Chest computed tomography showed no evidence of hilar or mediastinal lymphadenopathy. Left lower lobectomy with hilar and mediastinal lymph node dissection was performed. Postoperative histopathological examination revealed squamous cell carcinoma and no lymph node metastasis. On the other hand, a lobar bronchial lymph node presented a small lesion showing the dense proliferation of capillary blood vessels with elastic change. Immunohistochemically, the lesion was positive for factor VIII and CD34, leading to a diagnosis of primary hemangioma of the lymph node. Conclusion To our knowledge, this is the first case reported in the literature of hemangioma in a pulmonary hilar lymph node. Intranodal hemangioma needs to be differentiated from malignant vascular tumors. PMID:21266086

    Hemangioma is a mesenchymal benign tumor formed by blood vessels. Anomalies affect up to 10% of children and they are more common in females than in males. The aim of our study was to compare the treatment efficacy, namely the curative effect and adverse events, such as loss of pigment and appearance of scarring, between classical surgery techniques and laser techniques. For that reason a group of 223 patients with hemangioma was retrospectively reviewed. For treatment, a pulsed dye laser (PDL) (Rhodamine G, wavelength 595 nm, pulsewidth between 0.45 and 40 ms, spot diameter 7 mm, energy density 9-11 J cm-2) was used and the results were compared with a control group treated with classical surgical therapy under general anesthesia. The curative effects, mainly number of sessions, appearance of scars, loss of pigment, and relapses were evaluated as a marker of successful treatment. From the results it was evident that the therapeutic effects of both systems are similar. The PDL was successful in all cases. The surgery patients had four relapses. Classical surgery is directly connected with the presence of scars, but the system is safe for larger hemangiomas. It was confirmed that the PDL had the optimal curative effect without scars for small lesions (approximately 10 mm). Surgical treatment under general anesthesia is better for large hemangiomas; the disadvantage is the presence of scars.

  16. Scintigraphic evaluation of hepatic mass lesions: emphasis on hemangioma detection.

    1996-01-01

    Nuclear medicine imaging techniques continue to play a unique role in the evaluation of hepatic masses. Although many useful radiodiagnostic agents are available, the predominant nuclear medicine study used to evaluate hepatic masses in this decade is technetium-labeled red blood cell "blood-pool" scintigraphy. Hepatic blood-pool scintigraphy is extremely useful for the confirmation or exclusion of benign hepatic hemangiomas. This technique was first described in the 1970s and has vastly improved since that time. This improvement has been caused predominantly by advancements in instrumentation, especially the development of single photon emission computed tomography (SPECT) imaging. However, a perfusion/blood-pool mismatch remains unchanged as the hallmark finding for hepatic hemangiomas. The sensitivity and specificity of blood-pool scanning for the detection of hemangiomas has continued to increase over the years, and has not been equaled or surpassed by other radiographic modalities, with the possible exception of magnetic resonance imaging. Furthermore, blood-pool imaging is relatively inexpensive, simple to perform, and highly accurate. When a suspected hepatic hemangioma is confirmed by a positive radionuclide blood-pool study, the clinical evaluation of patients with hepatic masses can generally be terminated. PMID:8623050

    Highlights: • PEDF was expressed and induced during the involuting phase of IH. • PEDF inhibited the cell growth of the involuting HemECs in an autocrine manner. • PEDF suppression restored the impaired cell growth of the involuting HemECs. - Abstract: Hemangioma is a benign tumor derived from abnormal blood vessel growth. Unlike other vascular tumor counterparts, a hemangioma is known to proliferate during its early stage but it is followed by a stage of involution where regression of the tumor occurs. The critical onset leading to the involution of hemangioma is currently not well understood. This study focused on the molecular identities of the involution of hemangioma. We demonstrated that a soluble factor released from the involuting phase of hemangioma-derived endothelial cells (HemECs) and identified pigment epithelium-derived factor (PEDF) as an anti-angiogenic factor that was associated with the growth inhibition of the involuting HemECs. The growth inhibition of the involuting HemECs was reversed by suppression of PEDF in the involuting HemECs. Furthermore, we found that PEDF was more up-regulated in the involuting phase of hemangioma tissues than in the proliferating or the involuted. Taken together, we propose that PEDF accelerates the involution of hemangioma by growth inhibition of HemECs in an autocrine manner. The regulatory mechanism of PEDF expression could be a potential therapeutic target to treat hemangiomas.

    Background: Hemangioma, a congenital vascular malformation, is the most common benign liver lesion that is usually remain stable subsequently requiring not treatment; however, complications such as abdominal pain or fullness, coagulation disturbances, and inflammatory syndrome may occur, demanding a specific treatment of hemangioma. Objectives: To assess the safety, feasibility and efficacy of trans-catheter arterial embolization (TAE) for the treatment of Liver hemangioma Patients and Methods: TAE was performed on 20 patients with liver hemangioma. The embolic agent used was polyvinyl alcohol (PVA) particles (300-400 micron, Jonson and Johnson Cordis, USA). All patients were followed up for 6 months. Imaging was carried out and patients were also evaluated symptomatically through telephone interview by a physician. Results: Twenty patients aged from 21 to 63 years (mean: 46.8, SD: 10.26) were included in this study. Post embolization syndrome, including abdominal pain, fever, and leukocytosis occurred in one patient 1 week after TAE and lasted for 3 days. No serious adverse event and TAE-related death was observed. None of the patient underwent another intervention including surgery. During follow up interval, decreased episode of abdominal pain was documented in all patients who had pain. Tumor enlargement was also stopped during the follow up. The average diameter of tumors was 97.00 mm (range: 25-200 SD: 47.85) and 88.95 mm (range: 23-195 SD: 43.27) before and after embolization, respectively. Comparison of images before and after TAE revealed statistically significant decrease in the size of lesion (P value: 0.004, t: 3.31). Conclusions: Our findings indicate that TAE is a safe and efficient procedure for the treatment of liver hemangioma. Further studies with larger sample sizes are required to support therapeutic effects of TAE. PMID:25737731

    Cavernous sinus (CS) hemangiomas are rare vascular abnormalities that constitute 0.4%-2% of all lesions within the CS. Cavernous sinus hemangiomas are high-flow vascular tumors that tend to hemorrhage profusely during resection, leading to incomplete resection and high morbidity and mortality. While Gamma Knife surgery (GKS) has proven to be an effective treatment of CS hemangiomas in the adult population, few reports of GKS for treatment of CS hemangiomas exist in the pediatric literature. Here, the authors present the first case of a 15-year-old girl with a biopsy-proven CS hemangioma who achieved complete resolution of her symptoms and a complete imaging-defined response following GKS. If suspicion for a CS hemangioma is high in a pediatric patient, GKS may be considered as an effective treatment modality, thus avoiding the morbidities of open resection. PMID:23082966

This is the first report, to our knowledge, of a tracheal cavernous hemangioma that presented with massive hemoptysis. The lesion was removed with a CO2 laser under rigid laryngoscopy. Endovascular tumors, such as tracheobronchial hemangiomas, should be considered a diagnostic option in cases of massive hemoptysis without a significant underlying lung lesion. PMID:25861344

    Aim To report a case of metastatic small-cell neuroendocrine carcinoma presenting as an isolated choroidal mass and initially misdiagnosed as a circumscribed choroidal hemangioma. Methods The clinical history, fundus findings, imaging, cytology and immunohistochemical features are described. Results An otherwise healthy 66-year-old man was referred for a left nasal scotoma and a diagnosis of circumscribed choroidal hemangioma. Cytology showed cohesive clusters of small-to-intermediate malignant cells. The atypical cells stained positively for chromogranin, thyroid transcription factor-1 and synaptophysin consistent with small-cell neuroendocrine carcinoma. Conclusion Small-cell neuroendocrine carcinoma metastatic to the choroid is extremely rare; however, it is particularly aggressive and should be included in the differential diagnosis of isolated choroidal lesions, even in otherwise healthy patients.

    Cavernous hemangioma of the larynx is an uncommon, difficult-to-diagnose vascular tumor for which there is no significant imaging literature to date. The possibility of improved diagnosis through RBC scanning might obviate injudicious biopsy and potential hemorrhage within the airway. Utilizing the radionuclide RBC scan, which labels the patient's own RBCs initially with cold pyrophosphate, and subsequently with technetium 99m as pertechnetate, we have identified successfully four patients with cavernous hemangioma of the larynx. All presented with a supraglottic mass involving at least the aryepiglottic fold and arytenoid region unilaterally. This report describes our satisfactory diagnostic imaging experience with the radionuclide RBC scan and suggests both its imaging specificity and its role in the management of this lesion.

    Hemangioma is a benign tumor of blood and lymphatic vessels. It is common in skin, mucosa and soft tissues, and its occurrence in lymph nodes is extremely rare. A 10 year-old she-camel was slaughtered at Nyala slaughterhouse, South Darfur State, Sudan. Grossly, the carcass was emaciated. The left ventral superficial cervical lymph node was enlarged, hard on palpation and protruded outside the body. Its cut surface was dark red in color and measured (18 cm) in diameter. Histopathologically, the sections revealed vascular masses were composed of non-encapsulated clusters of small and medium sized with thick and thin-walled, filled with blood, separated by courageous stroma and surrounded by closely packed proliferating capillaries. To the best of our knowledge, this is the first record of the left ventral superficial cervical lymph node hemangioma in a camel in the Sudan. PMID:26753134

    Lobular capillary hemangioma (LCH), also called pyogenic granuloma, is a benign vascular tumor that is pedunculated on the skin and the mucous membranes of the oral cavity. This disease occurs in all ages, but more often in the 3rd decade, and is seen in females more than males. LCH commonly appears in early childhood and affects males more than females in the pediatric age group. The gingiva, lips, tongue and buccal mucosa are the most common sites of mucosal LCH, but the nasal cavity is rare. Micro-trauma and hormonal factors are the most common etiologic factors. Epistaxis and nasal obstruction are the most marked symptoms. We describe the case of a 6-year-old girl with intra-nasal lobular capillary hemangioma presented with epistaxis and nasal obstruction. This should be considered in the differential diagnosis of childhood endonasal masses with bleeding. Total excision using endoscopic technique is the treatment of choice. PMID:14652770

    Hemangiomas are developmental vascular abnormalities and more than 50% of these lesions occur in the head and neck region, with the lips, tongue, buccal mucosa, and palate most commonly involved. They are considered as hamartomas rather than true neoplasms. Here we report a case of hemangioma of the body of the tongue, discussing the diagnostic aspects and treatment modalities of such lesion and emphasizing the role of the color Doppler ultrasonography, especially in the diagnosis and treatment. Factors such as patient's age, size and site of lesion and the proximity of lesion to vital structure are paramount in the determination of the therapeutic approach and surgical excision. Even though radiotherapy, cryotherapy, laser therapy, medical treatment, injection of sclerosing substances and the selective embolization of the lingual artery seem to have some efficacy, the author conclude that surgery is the therapy of choice in the isolated vascular lesions of the body of the tongue.

    Hepatic cavernous hemangioma must be included in the differential diagnosis of any hepatic solid mass. It is the second most common neoplasm of the liver, following intrahepatic metastases. With the exception of giant or symptomatic HCH, it does not require specific intervention. The ability to diagnose HCH radiologically (Table 2) has significant clinical importance. When confronted with clinical data and a preliminary radiologic study suggestive of HCH, serial planar blood-pool scintigraphy (with SPECT if the lesion is < 3-4 cm) should probably be the initial diagnostic examination. In comparison to MRI, it is safer, less expensive and easier for some patients to tolerate. For small, deep seated lesions or those adjacent to the heart or large vessels, MRI is the preferred test. Dynamic CT is probably most useful in patients with normal renal function in whom optimal imaging of the extrahepatic abdomen is desired. If the etiology of an incidental hepatic mass suspected to be an HCH is still not evident after these studies, angiography or biopsy are the remaining options. As described, angiography is sensitive and relatively specific for HCH. Although percutaneous biopsy may be associated with increased risk of bleeding, fine-needle biopsy has been shown to be safe for hemangiomas. However, fine-needle biopsy is more useful for confirming a suspected malignancy than for actually diagnosing hemangioma. PMID:8478723

    Backgrounds/Aims Liver hemangioma, the most common benign liver tumor, can be safely managed by clinical observation. However, surgical treatment should be considered in a subset of patients with giant hemangioma with abdominal symptoms. We reviewed the feasibility of total laparoscopic liver resection for giant hemangioma of >6 cm in diameter. Methods Nine consecutive patients who underwent total laparoscopic liver resection for giant hemangioma between August 2008 to December 2012 were included in this study. Medical records were retrospectively reviewed for demographic data, laboratory findings, and perioperative results. Results The median age of patients was 36 yrs (range, 31-63). Eight females and 1 male were included in the study. The median size of hemangioma was 11 cm in diameter (range, 6-18) and 5 patients had a hemangioma >10 cm. Indications for surgical treatments were abdominal symptoms in 4 patients, increased size in 5 patients, and uncertain diagnosis in 1 patient. The median operation time was 522 minutes for right hepatectomy, 220 minutes for left lateral sectionectomy, and 90 minutes for wedge resection. The median estimated blood loss was 400 ml (range, 50-900). There was no postoperative morbidity, including Clanvien-Dindo grade I. Conclusions The resection of giant hemangioma demands meticulous surgical technique due to high vascularity and the concomitant risk of intraoperative hemorrhage. Laparoscopic liver resection is feasible with minimal operative complication. Therefore, laparoscopic liver resection can be considered as an option for surgical treatment for giant hemangioma.

    Macrophage infiltration has been implicated in infantile hemangioma (IH), the most common tumor of infancy. However, the exact role of macrophages in IH remains unknown. This study aims to clarify the functional significance of macrophages in the progression of IH. The distribution of macrophages in human IH was analyzed, and our results revealed that polarized macrophages were more prevalent in proliferating IHs than in involuting IHs, which was consistent with the increased macrophage-related cytokines in proliferating IHs. In vitro results further demonstrated that polarized macrophages effectively promoted the proliferation of hemangioma stem cells (HemSCs) and suppressed their adipogenesis in an Akt- and extracellular signal-regulated kinase 1/2 (Erk1/2)-dependent manner. Moreover, M2- but not M1-polarized macrophages promoted the endothelial differentiation of HemSCs. Furthermore, mixing macrophages in a murine hemangioma model elevated microvessel density and postponed fat tissue formation, which was concomitant with the activation of Akt and Erk1/2 signals. Cluster analysis revealed a close correlation among the macrophage markers, Ki67, vascular endothelial growth factor (VEGF), p-Akt, and p-Erk1/2 in human IH tissues. Collectively, our results suggest that macrophages in IH contribute to tumor progression by promoting the proliferation and endothelial differentiation while suppressing the adipogenesis of HemSCs. These findings indicate that targeting the infiltrating macrophages in IH is a promising therapeutic approach to accelerate IH regression. PMID:26288359

    Infantile hemangiomas are the most common benign vascular tumors in infancy and childhood. As hemangioma could regress spontaneously, it generally does not require treatment unless proliferation interferes with normal function or gives rise to risk of serious disfigurement and complications unlikely to resolve without treatment. Various methods for treating infant hemangiomas have been documented, including wait and see policy, laser therapy, drug therapy, sclerotherapy, radiotherapy, surgery and so on, but none of these therapies can be used for all hemangiomas. To obtain the best treatment outcomes, the treatment protocol should be individualized and comprehensive as well as sequential. Based on published literature and clinical experiences, we established a treatment guideline in order to provide criteria for the management of head and neck hemangiomas. This protocol will be renewed and updated to include and reflect any cutting-edge medical knowledge, and provide the newest treatment modalities which will benefit our patients. PMID:24260591

    2010-01-01

    Introduction Cavernous hemangiomas of the uterus are extremely rare, benign lesions. A survey of the current literature identified fewer than 50 cases of hemangioma of the uterus. Case presentation We report a case of cavernous hemangioma of the uterus in a 27-year-old Malay, para 1 woman who presented at our hospital with torrential vaginal bleeding having been transferred by land ambulance from a district hospital 30 minutes away. 11 weeks previously she had an urgent cesarean section at our hospital. She had to undergo a hysterectomy to control her bleeding after other measures were unsuccessful. A histopathological report confirmed a diffuse ramifying hemangioma of the cervix and uterus with left hematosalpinx. Conclusion Most ramifying hemangioma lesions are asymptomatic and are found incidentally, but sometimes they may cause abnormal vaginal bleeding and hence should be included in the differential diagnosis of patients with vaginal bleeding. Hysterectomy is the primary mode of treatment in most symptomatic cases. PMID:20478031

    Background Hemangioma is a common benign tumor in the liver and usually asymptomatic. Scanty evidence concerning treatment modality of symptomatic hemangioma during pregnancy exists. Case A 35 year-old woman with giant hepatic cavernous hemangioma developed consumption coagulopathy due to the enlarged tumor, and underwent danaparoid therapy from 5 weeks of gestation (GW). Magnetic resonance image revealed giant hemangioma with 20 cm in diameter in the right lobe of the liver. A surgical operation of liver resection was successfully performed at 16 GW. Thereafter, the coagulopathy disappeared. She delivered a healthy male infant at 36 GW. Conclusion This is the first case report of surgical resection therapy for giant liver hemangioma during pregnancy. PMID:22905301

  1. A Potential Role for Notch Signaling in the Pathogenesis and Regulation of Hemangiomas

    2013-01-01

    Hemangiomas are the most common benign tumor of infancy, yet its pathogenesis and the mechanisms governing proliferation and involution are not well understood. It is believed that hemangiomas arise out of clonal, abnormal hemangioma endothelial cells (HemECs). The underlying anomaly of the HemEC is not known, although studies have shown that vascular endothelial growth factor (VEGF) and VEGF signaling may influence HemECs. Moreover, there are numerous subtypes of hemangiomas, with differences in natural history, potential for morbidity, and prognosis, and little is known how this relates to HemEC. The Notch signaling pathway is a highly conserved pathway across species from worms to mammals. Notch signaling has been shown to play a role during embryogenesis in directing vascular patterning and development and arterial and venous cell fate determination. Postnatally, it has been implicated in tumor angiogenesis in multiple malignancies. Notch signaling triggers tumor angiogenesis at least in part to stimulation by VEGF, thus establishing that there is a cross talk between the VEGF and Notch pathways. Given the presence of VEGF and its receptors in hemangiomas and known VEGF-Notch cross talk in tumor angiogenesis, the authors hypothesize that Notch signaling may contribute to hemangioma proliferation and involution. Preliminary studies of resected hemangioma specimens by reverse transcription polymerase chain reaction (RT-PCR) show that all 4 Notch receptors and 2 Notch ligands, Jagged1 and Delta-like ligand 4, are expressed by hemangiomas. These findings support a role for Notch in hemangiomas, meriting further analysis of the functional relevance of Notch signaling in hemangiomas. PMID:19169152

    The role of adding single-photon emission CT (SPECT) to /sup 99m/Tc-labeled RBC imaging of the liver was evaluated by specifically focusing on the differentiation between hepatic hemangioma and hepatocellular carcinoma. Planar RBC imaging followed by blood-pool SPECT scanning was performed in 77 patients with a total of 108 hemangiomas and in 29 patients with a total of 46 hepatocellular carcinomas. All lesions were smaller than 5 cm in diameter. Thirty-six (33%) of 108 hemangiomas were detected by planar delayed RBC imaging, whereas 63 (58%) were detected by the delayed RBC-SPECT scan. The smallest hemangioma shown by delayed RBC-SPECT scanning was 1.4 cm in diameter, compared with 1.7 cm by planar RBC scanning. When confined to nodules larger than 1.4 cm in diameter, 42% of hemangiomas (36/85) were detected by planar delayed RBC imaging, whereas 74% (63/85) were detected by delayed RBC-SPECT. Increase in sensitivity was noted in nodules 2.1-4.0 cm in diameter. No hepatocellular carcinomas were shown by delayed RBC planar or SPECT scans. We concluded that with the addition of SPECT, the sensitivity of delayed RBC scans in the detection of small hemangiomas is considerably improved. Delayed RBC-SPECT scanning can be used to distinguish hemangioma from hepatocellular carcinoma.

    Intraosseous cavernous hemangiomas of the skull are rare. Meningiomas are quite frequently encountered in a neurosurgical practice. The association between these two entities is nevertheless very uncommon. The authors present a case of a 72-year-old woman suffering from headache. The MRI showed a parietal meningioma with adjacent thick bone. The meningioma and the bone were removed. The histological examination confirmed the diagnosis of meningioma and revealed a cavernoma of the skull. The relationship between the lesions suggests more than a coincidental association. Several hypotheses are proposed to explain common causal connections. PMID:25960899

    A 62-year-old woman presented with a mobile abdominal palpable mass. She underwent MR examination twice. Because of the mobility of the mass, it was out of the field of view on the first MR examination. The second MR examination detected the mass, which showed heterogeneous signal intensity including low and high intensity on T2-weighted spin echo images. The mass, which was cavernous hemangioma with old hemorrhage, was difficult to differentiate from fibroma or thecoma of the ovary or subserosal leiomyoma of the uterus. PMID:10852659

    The treatment of infantile hemangiomas changed from the use of oral corticosteroids to oral propranolol on the serendipitous discovery of propanolol's clinical effectiveness in 2008. Since then, clinicians have begun to use topical beta blockers--in particular, timolol maleate 0.5% gel forming solution--with good effect. Topical beta blockers are now used for lesions with both deep and superficial components and those that are amblyogenic. When initiated in the proliferative phase of the lesion, the effectiveness of the treatment can be seen within days. There is no consensus on dosing, treatment bioavailability, or clinical assessment of lesions, but these are topics for future research. PMID:26408055

We report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. Although computed tomography (CT) and magnetic resonance imaging (MRI) showed several enhancing areas within the tumor, the substantial bone erosion and remodeling made it difficult to differentiate this cavernous hemangioma from other expansile maxillary sinus lesions.

    In this case, the authors describe the appearance of hemangioma, the most common benign tumor of the liver, on early and delayed in-111 CP antibody images. The early immunoscintigraphic images show intense blood pool activity comparable in appearance to labeled RBC imaging, the current procedure of choice for confirming the diagnosis of hemangioma. In combination with disappearance of blood pool activity on the late scintigraphic images, these findings are pathognomonic for hemangioma and sufficiently distinct from the appearance of hepatic metastases on in-111 labeled antibody images to obviate the need for further confirmatory diagnostic studies.

    PHACES syndrome is a pediatric syndrome with cutaneous and extra-cutaneous manifestations, such as Posterior fossa defects, Hemangiomas, Arterial lesions, Cardiac abnormalities/aortic coarctation, Eye abnormalities and Sternal cleft. Facial hemangiomas affect the 75% of patients and may arise on the oral mucosa or perioral cutaneous regions. In this study we treated 26 Intraoral Haemangiomas (IH) and 15 Perioral Haemangiomas (PH) with diode laser photocoagulation using a laser of 800+/-10nm of wavelength. For IH treatment an optical fiber of 320 μm was used, and the laser power was set ted at 4 W (t-on 200 ms / t-off 400ms; fluence: 995 J/cm2). For PH treatment an optical fiber of 400 μm at the power of 5 W was used (t-on 100 ms / t-off 300 ms; fluence: 398 J/cm2). IH healed after one session (31%), the other (69%) after two sessions of Laser therapy. In each session, only a limited area of the PH was treated, obtaining a progressive improvement of the lesion. Diode laser photocoagulation is an effective option of treatment for IH and PH in patients affected by PHACE because of its minimal invasiveness. Moreover laser photocoagulation doesn't have side effects and can be performed repeatedly without cumulative toxicity. Nevertheless, more studies are required to evaluate the effectiveness of the therapy in mid and long time period.

    Cavernous hemangioma is not a neoplasm, but rather a congenital venous malformation with the potential to develop in all parts of the body, though it is very rarely seen in the thymus. We report a case of cavernous hemangioma in the thymus partially resected. A 71-year-old woman presented with pericardial discomfort, and chest computed tomography (CT) showed a left lateral mediastinal mass which was 2.0 × 1.2 × 1.8 cm in size, with border regularity and without calcification. Its interior was partially enhanced. Three-dimensional chest computed tomography image showed a tortuous vessel connecting to the tumor. Surgical resection was performed for the purpose of providing a definitive diagnosis and treatment because a mediastinal tumor such as thymoma or teratoma was suspected. Partial resection of the thymus including the mass was done by utilizing a three-port, left-sided video-assisted thoracic surgery (VATS) approach with hoisting of the third rib with the patient in a spinal position. A wine-colored mass bulging from the surface of the left lobe of the thymus was identified along with the communicating vessel which could only be cut with an energy device. It is considered that thymic partial resection using VATS is a better option for small and non-infiltrative lesions. PMID:26943686

    The International Society for the Study of Vascular Anomalies (ISSVA) classification divides vascular lesions into two major entities: neoplasms originating from the vascular endothelium and vascular malformations. Although this concept has been widely accepted, little has been established regarding vascular lesions in deep organs, such as infantile hepatic hemangioma (IHH). The current nationwide survey identified 19 critical infantile hemangiomas during the most recent 5 years. On histopathology all the lesions examined were neoplastic, but portovenos shunt was found histologically or clinically in some cases. High-output cardiac failure, consumption coagulopathy, and respiratory distress were the major symptoms, and treatment-resistant coagulopathy seemed to be the most reliable predictor of fatal outcome. Although steroid has been the gold standard treatment for these lesions, 25% of the patients were totally insensitive to steroids, whereas propranolol had a prompt effect in one case. For critical IHH with steroid-insensitive thrombocytopenia and prothrombin time prolongation, novel therapeutic options including beta-blocker therapy, surgery, and liver transplantation should be urgently considered as alterative treatment.

    Cavernous hemangioma of the calvaria is a very rare disease, and patients usually present with headaches or a visible skull deformity. Few reports of patients presenting with intradiploic or epidural hemorrhages are found in the literature. No case of an intradural hemorrhage from a cavernous hemangioma of the skull has been reported to date. The authors present the case of a 50-year-old man in whom a symptomatic subdural hematoma (SDH) resulting from a cavernous hemangioma of the calvaria had hemorrhaged and eroded through the inner table of the skull and dura mater. The patient underwent surgery for evacuation of the SDH and resection of the calvarial lesion. Postoperatively, the patient experienced immediate relief of his symptoms and had no clinical or radiological recurrence. Calvarial cavernous hemangiomas should be considered in the differential diagnosis of nontraumatic SDHs. Additionally, skull lesions that present with intracranial hemorrhages must be identified and resected at the time of hematoma evacuation to prevent recurrences. PMID:15633993

    Purpose Ovarian hemangiomas are seen rarely. We present a case of an ovarian hemangioma occurring synchronously with contralateral mature cystic teratoma. Case history An 81-year-old woman presented with hypertension and hyponatremia. In ultrasonographic evaluation a pelvic mass was found located at the left ovary. Histologically, a mature cystic teratoma measuring 9.5 × 9 × 8 cm was seen in left ovary. In the right ovary an incidental vascular lesion measuring 3.5 × 1.5 × 1 cm was observed. Final histopathological examination of this lesion demonstrated a hemangioma of cavernous type. Conclusion To the best of our knowledge, this is the first ovarian hemangioma case occurring synchronously with contralateral mature cystic teratoma. PMID:20846106

    Introduction: Epitheloid hemangioma, a benign vascular tumor that arises in skin and soft tissues can also involve the skeletal system. Occasionally this has been reported from small tubular bones of the hand. Case Report: Authors report a case of epitheloid hemangioma of the middle phalanx in a young girl without any cutaneous manifestations. The lesion presented as a swollen middle finger, and plain radiographs showed a geographic area of destruction with cortical thinning and intra lesional calcifications. The case was managed by curettage and bone grafting. Histology confirmed this as a case of epitheloid hemangioma. Conclusion: Epitheloid hemangioma should be considered in the differential diagnosis of hand masses with expansile lytic lesions with cortical thinning.

    Primary intraosseous cavernous hemangiomas (PICHs) of the cranium are rare benign vascular tumors that account for about 0.2 % of all bone tumors and 10 % of benign skull tumors. They generally present as osteolytic lesions with honeycomb pattern of calcification. Completely ossified cavernous hemangioma of the calvarium in an adult has not been reported previously. A 28-year-old female presented to us with a large right parietal skull mass that had been present since the last 15 years. Total resection of the lesion was performed. Pathological examination was suggestive of cavernous hemangioma of the skull bone. Cavernous hemangioma should be considered as one of the differential diagnosis in any case of bony swelling of the calvarium so that adequate preoperative planning can be made to minimize blood loss and subsequent morbidity.

    Aim: The aim of this study is to highlight the development of pyogenic granuloma and hemangioma after the placement of dental implants. Materials and Methods: A literature search was performed using MEDLINE, accessed via the National Library of Medicine PubMed Interface, for articles published between 2000 and 2014 in English, relating to the occurrence of pyogenic granuloma or hemangioma in relation to dental implants. Results: Our search identified only four case reports of pyogenic granuloma and hemangioma related to dental implants as reported in the English literature. Conclusion: Placement of dental implants can cause development of pyogenic granuloma and hemangioma, indicating that placement of dental implants requires well-trained specialists with perfect skills in dental implantology. Furthermore, the critical selection of the appropriate case is of paramount importance to avoid the occurrence of such complications. PMID:25992330

    Context Hemangiomas are the commonest benign tumors of the spine. Most occur in the thoracolumbar spine and the majority are asymptomatic. Rarely, hemangiomas cause symptoms through epidural expansion of the involved vertebra, resulting in spinal canal stenosis, spontaneous epidural hemorrhage, and pathological burst fracture. Findings We report a rare case of a 73-year-old woman, who had been treated for two months for degenerative neurogenic claudication. On admission, magnetic resonance imaging and computed tomographic scans revealed a hemangioma of the third lumbar vertebra protruding to the epidural space producing lateral spinal stenosis and ipsilateral nerve root compression. The patient underwent successful right hemilaminectomy for decompression of the nerve root, balloon kyphoplasty with poly-methyl methacrylate (PMMA) and pedicle screw segmental stabilization. Postoperative course was uneventful. Conclusion In the elderly, this rare presentation of spinal stenosis due to hemangiomas may be encountered. Decompression and vertebral augmentation by means balloon kyphoplasty with PMMA plus segmental pedicle screw fixation is recommended. PMID:24090267

    Pregnancy is a well-known risk factor for incidental or asymptomatic vertebral hemangiomas becoming aggressive or symptomatic, most often during the third trimester of pregnancy, related to hemodynamic and endocrinal changes occurring during pregnancy. Many patients show spontaneous incomplete remission after delivery. We report a rare case of aggressive vertebral hemangioma in the postpartum period in a 26-year-old woman, who presented with upper backache with progressive spastic paraparesis. PMID:25988053

    Fetal brain tumors are rare. This report describes a giant posterior fossa capillary hemangioma treated with 3 mg/kg/day of propranolol for 6 months. Total regression was confirmed at 1 year, and no additional tumors were observed during the subsequent 2 years. No side effects relating to the use of this drug were detected; thus, the authors believe that propranolol may be useful for treating all intracranial capillary hemangiomas. PMID:26824594

    Hepatic cavernous hemangioma accounts for 73% of all benign liver tumors with a frequency of 0.4-7.3% at autopsy and is the second most common tumor seen in the liver after metastases. Patients affected by hemangioma usually have their tumor diagnosed by ultrasound abdominal examination for a not well defined pain, but pain persist after treatment of the hemangioma. The causes of pain can be various gastrointestinal pathologies including cholelithiasis and peptic ulcer disease.The malignant trasformation is practically inexistent. Different imaging modalities are used to diagnosis liver hemangioma including ultrasonography, computed tomography (CT), magnetic resonance (MR) imaging, and less frequently scintigraphy, positronemission tomography combined with CT (PET/CT) and angiography. Imaging-guided biopsy of hemangioma is usually not resorted to except in extremely atypical cases. The right indications for surgery remain rupture, intratumoral bleeding, Kasabach-Merritt syndrome and organ or vessels compression (gastric outlet obstruction, Budd-Chiari syndrome, etc.) represents the valid indication for surgery and at the same time they are all complications of the tumor itself. The size of the tumor do not represent a valid indication for treatment. Liver hemangiomas, when indication exist, have to be treated firstly by surgery (hepatic resection or enucleation, open, laproscopic or robotic), but in the recent years other therapies like liver transplantation, radiofrequency ablation, radiotherapy, trans-arterial embolization, and chemotherapy have been applied.

    Adult laryngeal hemangioma is an extremely rare and slowly progressing vascular tumor. The present study describes the first reported case of a male with a large laryngeal hemangioma that was treated by ultrasonic scalpel. A 61-year-old male presented to our hospital with a recurrent pharyngeal foreign body sensation, without hoarseness, hemoptysis, expectoration or dyspnea. A blue-black mass was detected in the right pyriform sinus, with a morular surface and a wide pedicle positioned lateral to the right arytenoid cartilage and aryepiglottic fold under electronic laryngoscopy. Following tracheotomy under local anesthesia, right superior laryngeal artery ligation and laryngeal hemangioma resection via a lateral neck hypopharyngeal approach were performed under general anesthesia using an ultrasonic scalpel. Pathological examination verified that the tumor was a cavernous hemangioma. On day 11, subsequent to post-operative anti-inflammatory and symptomatic treatment, electronic laryngoscopy showed that the arytenoid mucosal edema had decreased and that the movement of the arytenoid was good. There was no recurrence of hemangioma during a 2-year follow-up period. Therefore, it is recommended that complete surgical resection using an ultrasonic scalpel should be considered for similar cases involving large laryngeal hemangiomas. PMID:26137093

    Mucous membrane hemangiomas of the lip are common benign vascular tumors of infancy. This clinical study evaluated the efficacy and safety of liquid nitrogen cryotherapy of mucous membrane hemangiomas of the lip in early infancy. It was a retrospective review of 127 pediatric patients with hemangiomas involving the lips who underwent liquid nitrogen cryotherapy under inhalation general anesthesia with sevoflurane. Forty-one males and 86 females were treated. The overall median age at diagnosis of the mucous membrane hemangiomas was 3.6 months (range, 7 days to 18 months). The oral mucous membrane hemangioma involved the vermilion of the lower lip in 78 cases (61.4%), the vermilion of the upper lip in 40 cases (31.5%), and both vermilions in 9 cases (7.1%). No complications because of anesthesia occurred. The mean follow-up was 10 months, with a range of 8 to 14 months; 94 lesions (74.0%) were completely involuted, 22 lesions (17.3%) were mostly involuted, 11 lesions (8.7%) were partially involuted, and no lesion showed a small amount of involution. Liquid nitrogen cryotherapy is an effective, simple, and safe treatment for mucous membrane hemangiomas of the lip in early infancy. PMID:19158525

    As most hemangiomas and tattoos require many sessions to be cured completely by argon-laser or conventional therapy I developed a new combined surgical and laser-therapy method for large hemangiomas and tattoos. This is a three step method. First: The skin lesion is treated by argon-laser with the point by point method, developed by ourself. Second: Under local or general anaesthesia a) the hemangioma is partially excised and undermined letting only the skin which is already treated by argon-laser-beams. Than the hemangioma is exstirpated in toto, the wound closed by running intradermal sutures and a pressure bandage applied, b) the tattoo is abraded as deep as possible, draped by lyofoam. Then a pressure bandage is applied. Third: The hemangioma as well as the tattoo are treated by argon-laser-beams after the operation. This method is safe and effective, gives good results, minimal scars in the case of hemangiomas and tattoos. In this paper the method is described and some cases are illustrated by pre- and postoperational photographs.

    Systemic corticosteroid therapy has been used to treat hemangiomas for 30 years; yet, there are no studies of possible complications. We reviewed the database of the Vascular Anomalies Center at the Boston Children's Hospital and gathered information on short- and long-term side effects in children who were given systemic corticosteroids for problematic hemangiomas. In addition, a questionnaire regarding early and late consequences was sent to the families of children who were treated with corticosteroids from 1983 to 1997. Of 300 patients with hemangiomas, 80 children were identified as having received a full course of systemic corticosteroids for problematic tumors. Complete data were collected on 62 of these children. The response rate to the questionnaire was 78 percent (n = 62 of 80). The initial dose of corticosteroid varied from 2 to 3 mg/kg/ day. Duration of therapy ranged from 2 to 21 months (mean, 7.9 months; median, 6.5 months). The follow-up interval from the cessation of therapy ranged from 6 months to 15 years (mean, 4 years; median, 3 years). Short-term complications included cushingoid facies (n = 44; 71 percent), personality changes (n = 18; 29 percent), gastric irritation (n = 13; 21 percent), fungal (oral or perineal) infection (n = 4; 6 percent), and diminished gain of height (n = 22; 35 percent) and weight (n = 26; 42 percent). A total of 91 percent of children who had diminished gain of height (n = 20) returned to their pretreatment growth curve for height by 24 months of age. One child, who was treated at another institution with a dose of 20 mg/kg/day for 6.5 months that was slowly tapered over 18 months, was petite 6 years after ending therapy. Another child treated with an initial dose of 2 mg/kg/day for 5 months was smaller than predicted at the age of 6 years, but she was born prematurely and was on ventilatory support for respiratory distress. Three children treated with the standard dose and duration were at a low percentile for weight

    Intramuscular hemangiomas (IMHs) of the masseter muscle are extremely rare in the head and neck region and, thus, are often misdiagnosed as parotid tumors prior to surgery. Excisional resection remains the standard treatment for IMH. Since these tumors are located on the proximal side of the facial nerve, it is important to preserve the facial nerve during surgery. This study reports the case of a 57-year-old male who presented with a progressive tender swelling on the right side of the face, which had been present for >6 months. Computed tomography of the neck revealed a heterogeneous highly-vascularized mass located in the superficial layer of the masseter muscle. The patient subsequently underwent surgical resection via a collar incision, and pathological examination revealed a cavernous IMH. During the one-year follow-up period, the patient exhibited a good prognosis, and one-year magnetic resonance imaging revealed no local recurrence. PMID:26998058

    Umbilical cord hemangiomas are rare, and the natural history is poorly understood. We present a case where the clinical course was complicated by distal umbilical cord edema, episodes of proximal obstruction of umbilical artery blood flow, transient fetal pleural and pericardial effusions, and position-dependent abnormal fetal heart rate monitoring with periods of sustained fetal tachycardia. Delivery was performed for fetal growth restriction with abnormal fetal surveillance. This case highlights possible mechanisms for fetal decompensation as well as the importance of a multifaceted approach to the management of an umbilical cord mass using multiple tools for fetal assessment. © 2016 Wiley Periodicals, Inc.

    AIM: Hepatic cavernous hemangioma (HCH) is the most common benign tumor of the liver and its management is still controversial. Recent success in situ radiofrequency ablation of hepatic malignancies has led us to consider using this technique in patients with HCH. This study was to assess the efficacy, safety, and complications of percutaneous radiofrequency ablation (PRFA) under ultrasonography guidance in patients with HCH. METHODS: Twelve patients (four men and eight women, age ranged 33-56 years, mean age was 41.7 years) with 15 hepatic cavernous hemangiomas (2.5 cm to 9.5 cm) were treated using the RF-2000 generator and 10-needle LeVeen electrode percutaneously guided by B-ultrasound. Lesions larger than 3 cm were treated by multiple overlapping ablations that encompass the entire lesion as well as a rim of normal liver tissue (approximately 0.5 cm). RESULTS: All the patients who received PRFA therapy had no severe pain, bleeding or bile leakage during and after the procedures. Nine to 34 months’ follow-up (mean, 21 months) by ultrasound and/or spiral CT scan demonstrated that the ablated lesions in this group were shrunk remarkably, and the shrunken range was 38%-79% (mean, 67% per 21 months). The contrast enhancement was disappeared within the tumor or at its periphery in all cases on spiral CT scans obtained 3 to 6 months after treatment. CONCLUSION: The results of this study suggest that PRFA therapy is a mini-invasive, simple, safe, and effective method for the treatment of selected patients with HCH. PMID:12970923

    Objective The purpose of this study is to investigate whether acoustic radiation force impulse (ARFI) elastography with ARFI quantification and ARFI 2-dimensional (2D) imaging is useful for differentiating hepatic hemangiomas from malignant hepatic tumors. Materials and Methods One-hundred-and-one tumors in 74 patients were included in this study: 28 hemangiomas, 26 hepatocellular carcinomas (HCCs), three cholangiocarcinomas (CCCs), 20 colon cancer metastases and 24 other metastases. B-mode ultrasound, ARFI 2D imaging, and ARFI quantification were performed in all tumors. Shear wave velocities (SWVs) of the tumors and the adjacent liver and their SWV differences were compared among the tumor groups. The ARFI 2D images were compared with B-mode images regarding the stiffness, conspicuity and size of the tumors. Results The mean SWV of the hemangiomas was significantly lower than the malignant hepatic tumor groups: hemangiomas, 1.80 ± 0.57 m/sec; HCCs, 2.66 ± 0.94 m/sec; CCCs, 3.27 ± 0.64 m/sec; colon cancer metastases, 3.70 ± 0.61 m/sec; and other metastases, 2.82 ± 0.96 m/sec (p < 0.05). The area under the receiver operating characteristics curve of SWV for differentiating hemangiomas from malignant tumors was 0.86, with a sensitivity of 96.4% and a specificity of 65.8% at a cut-off value of 2.73 m/sec (p < 0.05). In the ARFI 2D images, the malignant tumors except HCCs were stiffer and more conspicuous as compared with the hemangiomas (p < 0.05). Conclusion ARFI elastography with ARFI quantification and ARFI 2D imaging may be useful for differentiating hepatic hemangiomas from malignant hepatic tumors. PMID:24043967

    Anastomosing hemangioma is a recently described, unusual variant of capillary hemangioma which seems to be unique for the genitourinary system, with a particular proclivity for the kidney. Histologically, it is characterized by a unique sinusoidal architecture reminiscent of splenic parenchyma that can lead to concern for angiosarcoma. We herein report a further case of anastomosing hemangioma originating in the right kidney of a 48-year-old Chinese man. The patient had a past medical history significant for hepatocellular carcinoma; this tumor was incidentally identified as an asymptomatic right renal mass during the periodical surveillance of the hepatic cancer. The resected tumor measured 2.5cm in maximum diameter and microscopically demonstrated an overall lobulated growth pattern with alternating cellular areas composed of anastomosing sinusoidal capillary-sized vessels lined by hobnail endothelial cells, and edematous, hyaline paucicellular areas. Cytologically the tumor cells were generally bland and exhibited positivity for CD31, CD34 immunohistochemically. The patient had been in a good status without evidence of tumor recurrence 12 months after the surgery. This rare variant renal hemangioma is in need of more recognition and should not be over-diagnosed as a malignance, particularly angiosarcoma. PMID:23573324

    Soft tissue hemangiomas are commonly encountered lesions, accounting for 7-10 % of all benign soft tissue masses (Mitsionis et al. J Foot Ankle Surg 16(2):27-9, 2010). While the literature describes the great majority of hemangiomas as asymptomatic and discovered only as incidental findings, they do have the potential to induce reactive changes in neighboring structures (Pastushyn et al. Surg Neurol 50(6):535-47, 1998). When these variants occur in close proximity to bone, they may elicit a number of well-documented reactive changes in osseous tissue (Mitsionis et al. J Foot Ankle Surg 16(2):27-9, 2010; DeFilippo et al. Skelet Radiol 25(2):174-7, 1996; Ly et al. AJR Am J Roentgenol 180(6):1695-700, 2003; Sung et al. Skelet Radiol 27(4):205-10, 1998). However, instances of direct extension into bone by soft tissue hemangiomas--that is, infiltration of the mass's vascular components into nearby osseous tissue--are currently undocumented in the literature. In these cases, imaging plays an important role in differentiating hemangiomas from malignant lesions (Mitsionis et al. J Foot Ankle Surg 16(2):27-9, 2010; Sung et al. Skelet Radiol 27(4):205-10, 1998; Pourbagher, Br J Radiol 84(1008):1100-8, 2011). In this article, we present such a case that involved the sacral spine. Imaging revealed a soft tissue mass with direct extension of vascular components into osseous tissue of the adjacent sacral vertebrae. Biopsy and subsequent histopathologic examination led to definitive diagnosis of soft tissue hemangioma. While MRI is widely regarded as the gold standard imaging modality for evaluating hemangiomas, in this report we describe how CT can aid in narrowing the differential diagnosis when one encounters a vascular lesion with adjacent osseous changes. Furthermore, we review the literature as it pertains to the imaging of soft tissue hemangiomas that occur in proximity to osseous tissue, as well as correlate this case to current theories on the pathogenesis of hemangiomas

    Hemangioma and vascular malformations in the field of oral and maxillofacial surgery is a pathology more often found in recent years in patients. The aim of this study was to evaluate the efficacy of the laser photocoagulation performed with a diode laser (Ga-Al-As) 980 nm wavelength in the treatment of vascular lesions which are located on the oral and maxillofacial areas, using color Doppler ultrasonography for evaluation of the results. We also made a comparison between laser therapy and sclerotherapy in order to establish treatment protocols and recommendations associated with this pathology. We conducted a controlled study on a group of 92 patients (38 male and 54 female patients, with an average age of 36 years) having low flow hemangioma and vascular malformations. Patients in this trial received one of the methods of treatment for vascular lesions such as hemangioma and vascular malformations: laser therapy or sclerotherapy. After laser therapy we have achieved a reduction in size of hemangioma and vascular malformations treated with such a procedure, and the aesthetic results were favorable. No reperfusion or recanalization of laser treated vascular lesions was observed after an average follow-up of 6 to 12 months. In case of sclerotherapy a reduction in the size of vascular lesions was also obtained. The 980 nm diode laser has been proved to be an effective tool in the treatment of hemangioma and vascular malformations in oral and maxillofacial area. Laser therapy in the treatment of vascular lesions was more effective than the sclerotherapy procedure.

    Hemangiomas may present in infancy as soft tissue masses. Occasionally these lesions may be extensive or may not be clinically recognized as a hemangioma, often causing concern for the presence of a malignant lesion. In later childhood these lesions, which may be occult, may cause overgrowth of an extremity. Evaluation of soft tissue masses suspected of being a hemangioma utilizing Technetium 99m labelled red blood cells has been very valuable. This method allows a dynamic evaluation of first pass blood flow. Subsequent static scintiphotos allow an assessment of the lesion itself. These scintiphotos may be obtained sequentially to evaluate therapy. Twenty patients were evaluated by this method ranging in age from two months to eleven years. There were 13 females and seven males. Lesions evaluated by this method include six hemangiomas of the head and neck: parotic region (2), facial (3), and tongue (1). Extremity lesions were evaluated in six children including both upper extremity (1) and lower extremity (5). Torso lesions evaluated include chest wall (2), abdominal wall (2), and one hemangioma of the gut. This procedure is quickly performed on an outpatient basis, has high anatomic resolution, provides and assessment of these lesions in a manner not available by any other imaging procedure and usually requires no sedation. The radiation exposure for this procedure is low (approximately, a 400mR total body dose) and has been well tolerated by both patients and their parents. Scintigraphic evaluation should be the first diagnostic method utilized in the evaluation of these lesions.

    Congenital hemangioma is a rare vascular tumor that forms in utero. Postnatally, the tumor either involutes quickly (i.e., rapidly involuting congenital hemangioma [RICH]) or partially regresses and stabilizes (i.e., non-involuting congenital hemangioma [NICH]). We hypothesized that congenital hemangiomas arise due to somatic mutation and performed massively parallel mRNA sequencing on affected tissue from eight participants. We identified mutually exclusive, mosaic missense mutations that alter glutamine at amino acid 209 (Glu209) in GNAQ or GNA11 in all tested samples, at variant allele frequencies (VAF) ranging from 3% to 33%. We verified the presence of the mutations in genomic DNA using a combination of molecular inversion probe sequencing (MIP-seq) and digital droplet PCR (ddPCR). The Glu209 GNAQ and GNA11 missense variants we identified are common in uveal melanoma and have been shown to constitutively activate MAPK and/or YAP signaling. When we screened additional archival formalin-fixed paraffin-embedded (FFPE) congenital cutaneous and hepatic hemangiomas, 4/8 had GNAQ or GNA11 Glu209 variants. The same GNAQ or GNA11 mutation is found in both NICH and RICH, so other factors must account for these tumors' different postnatal behaviors. PMID:27058448

    Introduction: Infantile hemangiomas of the airway are diagnosed at bronchoscopy as part of the investigation of stridor or other respiratory symptoms. Here, we present three-dimensional computed tomography (3D-CT)/bronchoscopy findings of submucosal subglottic hemangioma missed at bronchoscopy. Case Presentation: We report on the clinical usefulness of 3D-CT/bronchoscopy as the primary diagnostic tool and follow-up method in the evaluation of suspected airway infantile hemangiomas, especially when the hemangioma is the submucosal type. Conclusions: 3D-CT/bronchoscopy will reduce the need for invasive laryngoscopic studies and help to diagnose submucosal hemangiomas undetected on laryngoscope. Additionally, 3D-CT/bronchoscopy will help evaluating the extent of the lesion, degree of airway narrowing, and treatment response. PMID:26848371

    Introduction: Bony hemangiomas are rare lesions in growing skeleton. Affection of the epiphyseal plate by a bony hemangioma leading to growth retardation is rare. Case report: We report the radiological picture of a juxtaphyseal osseous hemangioma affecting the capital femoral physis leading to coxa vara and coxa breva deformity. This hemangioma is also a rarity as it has both intracortical and intra medullary components. A diagnostic and therapeutic CT guided core needle biopsy/decompression was performed to confirm the histopathological diagnosis and to decompress the lesion. Patient was treated conservatively with shoe raise and regular checkups and at two year follow-up there were no interval changes noted on the radiographs with patient completely asymptomatic. Conclusion: Juxtaphyseal hemangiomas may be amenable to needle decompression, however longer follow will be required to assess the further response.

    Most renal neoplasms in adults are epithelial in origin and mesenchymal tumors are rarely encountered. Vascular tumors and tumor-like lesions account for a very small subset. Hemangioma of the kidney is a rarely seen benign vascular neoplasm that probably arises from angioblastic cells. Its general sign is macroscopic hematuria with or without pain. Preoperative diagnosis is difficult or impossible. Previously, spontaneous rupture of the kidney caused by renal hemangioma was not reported in the English literature. In this study, two cases with a history of nephrogenic hypertension who presented with spontaneous renal rupture are presented. There wasn’t any trauma history in the background of our patients. A long-standing nephrogenic hypertension was present in both patients. Patients underwent radical nephrectomy due to rupture of the renal tumor. In histopathological examination, capillary hemangioma was detected in the renal medulla in both cases. Patients didn’t need antihypertensive therapy during the postoperative period. PMID:26623154

    Intraosseous hemangiomas are one of the rarest lesion of jaw bones (0.5–1%) occurring most commonly in vertebral column, skull bone, and rarely in mandible. Mainly occurs in the second decade of life with female: male predilection (2:1). Origin of hemangiomas is still debatable. World Health Organization considers it as a true benign neoplasm of vascular origin, and many authors believe it to be a hamartoma. It is very difficult to diagnose due to variable clinical and radiological features. A biopsy is not done on a routine basis due to a higher risk of hemorrhage. Management is very difficult because of massive vascular network in that region. Here, we are presenting a case report of a 14-year-old boy with intraosseous hemangioma of right body of mandible, which was treated with en bloc surgical resection of mandible and followed by reconstruction.

    Intramuscular hemangiomas are rare, benign tumors of vascular origin. The masseter is the muscle most commonly involved in the head and neck region. Because of their infrequency, deep location, and unfamiliar presentation, these lesions are seldom correctly diagnosed clinically. This case report presents a severe facial asymmetry caused by a left intramasseteric cavernous hemangioma in a 3-year-old boy. We were unaware of the exact nature of the tumor until intraoperative examination. The routine investigations performed before operation failed to establish a diagnosis. Surgical excision was performed, and 1 year after the operation we observed that the patient's facial asymmetry had been corrected. In this article, we review the literature on intramasseteric hemangioma, discuss the clinical and radiologic diagnostic methods, and review the treatment methods. PMID:15224828

    Background: The authors present the unique case of a dural-based, infantile hemangioma located in the posterior fossa of a 15-day-old infant. Case Description: The patient presented with hydrocephalus. The lesion was identified by magnetic resonance imaging and was subsequently resected. Diagnosis of the lesion was confirmed with immunohistochemistry staining. The patient's hospital course was complicated by transverse sinus thrombosis and a cerebrospinal fluid leak that were treated with anticoagulation therapy and ventriculoperitoneal shunt placement, respectively. Conclusion: Although hemangiomas are benign entities, our patient's lesion was in the posterior fossa causing compression and hydrocephalus that necessitated resection. We encourage others to consider the possibility of hemangioma in the differential diagnosis of dural-based posterior fossa lesions in infants. PMID:27213106

    Ovarian hemangiomas are benign and rare tumors of female genital tract with less than 60 reported cases in the literature. A 38- yr- old woman was admitted to Be'sat Hospital, Tehran, Iran in 2012, due to severe abdominal pain. Ultrasound evaluation revealed a 6 cm left ovarian cystic mass and serum tumor markers were normal. Then, left salpingo-oophorectomy was performed for the patient. Microscopic examination revealed a follicular cyst and an incidental cavernous hemangioma consisting thin-walled vascular channels filled with blood that lined with flatten endothelial cells. In IHC staining strong immunoreactivity for CD31 and CD34 were seen, finally, the diagnosis of primary ovarian hemangioma, cavernous-type was made. The clinicopathologic presentation of this unusual benign tumor is discussed. PMID:26870145

    We report a case of a very rare tumor of the ovary with an unusual presentation; an ovarian hemangioma with massive ascites and elevated CA125. A 57-year-old woman presenting with elevated CA125, massive ascites and a left solid adnexal mass of 60 x 47 mm, with calcification and increased blood flow at Doppler examination, was submitted to laparotomy. Frozen section was inconclusive and a staging procedure which complicated the patient was performed. Pathologic examination revealed cavernous hemangioma which is an extremely rare tumor of the ovary. Although it is very unusual, an ovarian hemangioma may present with ascites and elevated CA125 and the differential diagnosis from ovarian cancer should be considered. PMID:16620071

    Pancreatic hemangioma is a rare type of benign vascular tumor. Low clinical suspicion and inability of current cross sectional imaging techniques to differentiate it from other pancreatic lesions, contribute to the difficulty in making the correct diagnosis. Without a definitive diagnosis, and due to concern for malignancy, in many instances, surgery is performed. We report a case of pancreas cavernous hemangioma in an 18-year-old female. The patient presented with three-month history of epigastric pain. Physical examination and routine blood tests were normal. Abdominal Computed Tomography scan revealed a 5 cm × 6 cm complex non-enhancing cystic mass in the head of pancreas. Magnetic resonance imaging, endoscopic ultrasonography (EUS) and EUS guided fine needle aspiration cytology were non-diagnostic. Because of uncontrolled symptoms, the patient underwent surgical resection. Histopathology and Immunohistochemical staining confirmed the diagnosis of cavernous hemangioma of pancreas. PMID:26361427

    Patient: Female, 27 Final Diagnosis: LV hemangioma Symptoms: Palpitation • dyspnea • fatigue Medication: — Clinical Procedure: Posterior atriotomy Specialty: Cardiology Objective: Rare disease Background: Cardiac tumors are quite rare, and differential diagnosis of them is challenging. Case Report: A young lady with a history of palpitations, dyspnea, and fatigue was proven by transthoracic echocardiography and cardiac magnetic resonance imaging to have a mobile left ventricular mass with rounded contour attached to the mid-part of the interventricular septum. The mass was approached via a posterior inter-atrial approach to avoid left ventriculotomy and provide adequate exposure to completely excise the tumor and control its pedicle with minimal cardiac trauma. Histological examination of the mass was diagnostic of capillary and sinusoidal hemangioma. Conclusions: Complete excision of cardiac hemangioma is recommended once it is diagnosed, for histopathologic diagnosis and because of the possibility of serious complications. PMID:27384944

    An 8-year-old 7.9 kg castrated male Shih-tzu dog was presented to surgery with polyuria-polydipsia, intermittent abdominal pain and dermatological problems. The unilateral enlargement of the right adrenal gland was observed through ultrasound examination and based on this examination a hyperadrenocorticism was suspected. Upon physical examination, regional erythema was observed in the skin. An abdominal CT scan showed a well-defined retroperitoneal mass. Adrenalectomy via a midline abdominal approach was performed as well as optional treatments upon the approval of the owners. The histopathological diagnosis was that of an adrenal hemangioma without evidence of malignancy. Adrenal hemangioma was incidentally found in this dog during histological examination and this finding was an extremely rare case of the primary hemangioma in the adrenal gland. PMID:23706763

    Infantile hemangiomas (IHs) are common, benign vascular tumors of infancy, with more than half affecting the head and neck region. IHs involving the lips and oral cavity can often present to the oral surgeon and the pedodontist. Till date, several doubts exist among clinicians regarding the use of propranolol to treat infantile hemangiomas in neonates and small infants, appropriate dose, treatment duration, side effects, response, and long-term follow-up. We present a 2-month-old male infant with extensive hemangioma involving the face, orbit, buccal mucosa and palate with feeding difficulties, and risk of life-threatening complications such as airway compromise, aspiration, and visual loss which showed excellent response with high-dose propranolol and had no side effects. We also reviewed literature for the mechanism of action of propranolol and possible minor and serious side effects. PMID:27307684

    Background: Congenital hemangiomas are benign vascular tumors, and the intracranial counterpart was described in very few cases. Case Description: A newborn presented with an intracranial tumor associated with an arachnoid cyst, diagnosed by antenatal ultrasound at 37 weeks of gestation. Surgery was indicated due to increased head circumference and bulging fontanelle, and a complete resection of an extra-axial red–brown tumor was performed at the 3rd week of life. Microscopy revealed a hemangioma. Conclusion: Hemangioma is a rare differential diagnosis that must be considered in extra-axial intracranial tumors affecting infants and neonates. The radiological features are not helpful in differentiating from other tumors, and surgery is indicated when the diagnosis is uncertain or whenever there are signs of increased intracranial pressure.

    Abstract The aim of the study was to evaluate the feasibility, safety, and efficacy of computed tomography (CT)-guided radiofrequency (RF) ablation combined with transcatheter arterial embolization (TAE) to treat large (≥10 cm) hepatic hemangiomas. We retrospectively reviewed our sequential experience with 15 large hepatic hemangiomas in 15 patients. The mean diameter of the 15 hemangiomas was 13.0 ± 2.2 cm (10.0–16.0 cm). RF ablation combined with TAE treatment was performed successfully in all patients. The mean diameter of the hemangiomas decreased from 13.0 ± 2.2 to 7.1 ± 2.0 cm (P < 0.001) after TAE treatment. Out of 15 hepatic hemangiomas, 14 (93.3%) showed no enhancement on CT or MRI indicating complete ablation after RF treatment. The mean diameter of the ablation zone decreased to 6.1 ± 2.0 cm 1 month after ablation and further decreased to 4.9 ± 1.6 cm 6 months after ablation. There were 6 complications related to the ablation in 4 patients. According to the Dindo–Clavien classification, all the complications were minor (Grade I). RF ablation combined with TAE is a safe and effective treatment for large hepatic hemangiomas. TAE can improve the disruption of lesion blood supply and reduce lesion size to facilitate subsequent RF ablation and reduce the risk of ablation-related complications. PMID:27082617

    Multiple synchronous tumors presenting in infancy raise concern for inherited or sporadic cancer predisposition syndromes, which include Beckwith-Wiedemann syndrome, familial adenomatous polyposis syndrome, and Li-Fraumeni syndrome. We report a case of a 7-month-old previously healthy male born following an in vitro fertilization-assisted twin pregnancy who presented with new-onset refractory shock, severe acidosis, and rapid decline over several hours. An autopsy revealed a ruptured liver involved by hepatoblastoma, an adrenal gland involved by neuroblastoma, and multiple cutaneous capillary hemangiomas. Standard genetic testing demonstrated that both twins were Gaucher disease (GD) carriers without evidence of other known cancer predisposition syndromes. This report describes a unique association of multiple synchronous tumors, which underscores the utility and importance of the pediatric autopsy. Moreover, given that the reported child was a GD carrier, the possibility the tumors were the result of a GD-mediated cancer-associated phenotype or an unrecognized sporadic clinical syndrome remains an unanswered, but intriguing, question worthy of further investigation.

    We report 3 cases of circumscribed choroidal hemangioma (CCH) effectively managed with intravitreal bevacizumab. One patient (case 1) who had recurrent CCH (1.6 mm in thickness) with prior laser photocoagulation was treated with intravitreal bevacizumab alone. Two patients (case 2 and 3) who had CCH (2.4 mm and 2.2 mm in thickness, respectively) with recent visual impairment were treated with bevacizumab followed by photodynamic therapy (PDT). Ophthalmic evaluations included visual acuity, ophthalmoscopic examination, fluorescein angiography, ultrasonography, and optical coherence tomography. Patients were followed up for 6-9 months. After therapy, all patients showed improved visual acuity due to complete resorption of subretinal fluid and macular edema. Ultrasonography demonstrated a reduction of the thickness of CCH in case 1 and complete regression of the lesions in case 2 and 3. No patient showed tumor recurrence. Intravitreal bevacizumab, alone or in combination therapy with PDT, may be a useful alternative for the treatment of symptomatic CCH with subretinal fluid. PMID:19568366

    A patient who had disseminated vascular tumors involving the bilateral ovaries, bilateral lungs and pleura, pericardium, and mediastinum is reported. The tumors were histologically of the capillary, and partly the cavernous, type of hemangioma. However, endothelial cell growth was prominent in some areas, especially in the lung, and the histology of the lung tumor resembled epithelioid hemangioendothelioma or intravascular bronchiolo-alveolar tumor (IVBAT). In the endocardium of the right atrium, an endothelial tumorous projection was observed, and there were tiny foci of tumor cell nests in the abdominal venous wall. Small lymphangiomas were also found in the subcapsular region of the spleen. These findings suggest that there had been an abnormal proliferation of systemic endothelial cells and that tumors of endothelial cell origin with diverse histological patterns developed with this condition as a background. The autopsy finding of fibrin thrombi in multiple organs as well as laboratory data including thrombocytopenia suggest that this case belongs to the "Kasabach-Merritt syndrome." PMID:3673576

    Between 1920 and 1959, 9675 women were irradiated in infancy for skin hemangioma at Radiumhemmet, Stockholm. They were exposed to low to moderate doses of ionizing radiation. The mean age at first exposure was 6 months and the mean absorbed dose to the breast anlage was 0.39 Gy (range < 0.01-35.8 Gy). The breast cancer incidence was analyzed by record linkage with the Swedish Cancer Register for the period 1958-1986. Seventy-five breast cancers were found after a mean absorbed dose of 1.5 Gy in the breasts with cancer. The analyses showed a significant dose-response relationship with a linear model estimate for the excess relative risk (ERR) of 0.38 at 1 Gy (95% CI 0.09-0.85). This relationship was not modified significantly by age at exposure or by dose to the ovaries. The ERR increased significantly with time after exposure and for > 50 years after exposure the ERR at 1 Gy was 2.25 (95% CI 0.59-5.62). The fitted excess absolute risk (EAR) was 22.9 per 10{sup 4} breast-year gray. The breast absorbed dose and time after exposure were important risk determinants for breast cancer excess risk. Forty to 50 years of follow-up was necessary for the excess risk to be expressed. The study confirms previous findings that the breast anlage of female infants is sensitive to ionizing radiation. 17 refs., 6 figs.

    The present retrospective study aimed to analyze the outcome of patients with cavernous sinus hemangioma (CSH) treated with Gamma Knife radiosurgery (GKS). Between August 2011 and April 2014, 7 patients with CSHs underwent GKS. GKS was performed as the sole treatment option in 5 patients, whilst partial resection had been performed previously in 1 patient and biopsy had been performed in 1 patient. The mean volume of the tumors at the time of GKS was 12.5±10.2 cm3 (range, 5.3–33.2 cm3), and the median prescription of peripheral dose was 14.0 Gy (range, 10.0–15.0 Gy). The mean follow-up period was 20 months (range, 6–40 months). At the last follow-up, the lesion volume had decreased in all patients, and all cranial neuropathies observed prior to GKS had improved. There were no radiation-induced neuropathies or complications during the follow-up period. GKS appears to be an effective and safe treatment modality for the management of CSHs. PMID:26893777

    Since the introduction of propranolol in the treatment of complicated infantile hemangiomas (IH) in 2008, other different beta-blockers, including timolol, acetabutolol, nadolol and atenolol, have been successfully used for the same purpose. Various hypotheses including vasoconstriction, inhibition of angiogenesis and the induction of apoptosis in proliferating endothelial cells have been advanced as the potential beta-blocker-induced effect on the accelerated IH involution, although the exact mechanism of action of beta-blockers remains unknown. This has generated an extraordinary interest in IH research and has led to the discovery of the role of the renin-angiotensin system (RAS) in the biology of IH, providing a plausible explanation for the beta-blocker induced effect on IH involution and the development of new potential indications for RAS drugs such as angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers in the treatment of IH. This review is focused on the current use of cardiovascular drugs in the treatment of IH. PMID:26839658

    Infantile hemangioma (IH), the most common tumor of infancy, is characterized by rapid growth during infancy, followed by spontaneous involution over 5-10 years. Certain clinical observations have led to the suggestion that IH is triggered and maintained by hypoxia. We review the literature on the possible role of hypoxia in the etiology of IH, in particular, (1) the role of hypoxia inducible factor-1α (HIF-1α) and its downstream targets including GLUT-1 and VEGF; (2) the pathophysiological link between IH and retinopathy of prematurity; (3) hypoxic events in the early life including placental insufficiency, pre-eclampsia and low birthweight that have the potential to promote hypoxic stress; and (4) the evidence supporting the development of IH independent of HIF-1α. We also discuss these observations in the context of recent evidence of the crucial role of stem cells and the cytokines niche that governs their proliferation and inevitable differentiation, offering novel insights into the biology of IH. We propose that various triggers may simultaneously up-regulate HIF-1α, which is downstream of the renin-angiotensin system, specifically angiotensin II, which promotes production of HIF-1α. These developments shed light to the understanding of this enigmatic condition. PMID:26940670

    The management of oral and perioral hemangiomas depends on several clinical factors. Surgery of these benign lesions can at times be disfiguring, especially when the lips, muscles, or the maxilla and mandible are involved. In addition, by the very nature of these lesions, surgical treatment may be associated with excessive intra- and perioperative blood loss. A series of five patients who had hemangiomas in the perioral region and who were initially treated with transarterial microembolization, preoperatively in two cases and as the only treatment in three cases, is presented. The technique of microembolization is described and recommendations for its use are given. PMID:3856640

    Microvascular endothelial cells cultured in three-dimensional hydrogel scaffolds form a network of microvessel structures when implanted subcutaneously in mice, inosculate with host vessels and over time remodel into large ectatic vascular structures resembling hemangiomas. When compared to infantile hemaniomas similarities were noted including a temporal progression from a morphological appearance of a proliferative phase to the appearance of an involuted phase mimicking the proliferative and involutional phases of infantile hemangioma. Consistent with the progression of a proliferative phase to an involuted phase, both the murine implants and human biopsy tissue exhibit reduced expression of Ajuba, YAP and Survivin labeling as they progressed over time. Significant numbers of CD45+, CD11b+, Mac3+ mononuclear cells were found at the 2 week time point in our implant model which correlated with the presence of CD45+, CD68+ mononuclear cells observed in biopsies of human proliferative phase hemangiomas. At the 4 week time point in our implant model only small numbers of CD45+ cells were detected, which again correlated with our findings of significantly diminished CD45+, CD68+ mononuclear cells in human involutional phase hemangiomas. The demonstration of mononuclear cell infiltration transiently in the proliferative phase of these lesions suggests that the vascular proliferation and/or regression may be driven in part by an immune response. Gross and microscopic morphological appearances of human proliferative and involutional hemangiomas and our implant model correlate well with each other as do the expression levels of Hippo pathway components (Ajuba and YAP) and Survivin and correlate with proliferation in these entities. Inhibitors of Survivin and Ajuba (which we have demonstrated to inhibit proliferation and increase apoptosis in murine hemangioma cell tissue culture) may have potential as other beneficial treatments for proliferating infantile hemangiomas

    A 35 year-old man first noticed an elastic mass like breast tumor in his left chest 17 years ago. It enlarged to the size of a child’s head. Computed tomography showed a well-circumscribed mass in the left chest. Lumpectomy was performed. The mass was located under the thin major pectoralis muscle, covered with a white fibrous capsule. The specimen weighed 1360 g and measured 18 × 14 × 8 cm. Histological examination revealed a cavernous hemangioma. To the best of our knowledge, this is the first reported case of a chest hemangioma arising from connective tissue and located under the major pectoralis muscle. PMID:23555516

    A 36-yr-old woman with a past history of gastric neuro-endocrine carcinoma (carcinoid tumor) underwent 99mTc-red blood cell (RBC) scintigraphy for evaluation of a 2-cm echogenic liver mass demonstrated on ultrasound. Scan findings were typical of a cavernous hemangioma. On follow-up, however, there was progressive lesion enlargement; histopathology of the resected mass revealed neuro-endocrine carcinoma. This case report, one of the few examples of a false-positive 99mTc-RBC scan, highlights the need for cautious evaluation of focal liver masses, even when there are typical scintigraphic features of cavernous hemangioma.

    A painless, bluish, submucosal swelling on one side of the floor of the mouth usually indicates the presence of a ranula. Rarely, such a swelling may be caused by an inflammatory disease process in a salivary gland, a neoplasm in the sublingual salivary gland, a lymphatic nodular swelling, or embryologic cysts. We report a patient with swelling in the floor of her mouth that was clinically diagnosed as a ranula. Suspicion arose during surgery that it was a vascular tumor and, on histologic testing, the swelling was confirmed to be a hemangioma. To our knowledge, this is the first report in the literature of a hemangioma presenting as a ranula. PMID:19006063

Capillary hemangioma of the appendix is an extremely rare event and to the best of our knowledge only 4 cases have been reported in the English literature so far. In this case report we want to explain our experience with an extremely rare occurrence of capillary hemangioma of appendix in a 17-year-old girl presented with right lower quadrant pain that was operated with the clinical impression of acute appendicitis. The patient has been operated as a routine appendectomy with a completely uneventful postoperative period. PMID:27441077

    A patient presented with an acute episode of bright red blood in her stool. The incidental liver mass seen in segment 4 was suspected to represent a cholangiocarcinoma due to associated mild intrahepatic biliary ductal dilatation and suspicion for capsular retraction. Pathology confirmed that this lesion represented a sclerosing hemangioma. This case report corroborates prior observations that degenerative changes in hemangiomas—sclerosis, narrowing of vascular channels, thrombosis, infarct, hemorrhage—may produce atypical radiographic findings. Since these atypical radiographic features may suggest a primary or metastatic malignancy, the protean appearance of hemangiomas remains an important consideration in the evaluation of hepatic masses.

    A 44-year-old woman underwent surgery for lung cancer. Although preoperative computed tomography did not reveal a tiny nodule, pathological examination of the background lung showed that type II pneumocyte-like tumor cells grew papillary in an area of approximately 2.3 × 1.2 mm. This lesion exhibited hemorrhage, hemosiderosis, calcification, and varying degrees of fibrosis, leading to the diagnosis of sclerosing hemangioma. This is the first reported case of microscopic sclerosing hemangioma undetectable by chest computed tomography. PMID:21881377

    Hemangiomas of the head and neck are considered to be benign tumors of infancy that are characterized by a rapid growth phase with endothelial cell proliferation, followed by gradual involution. Central hemangiomas are a rare occurrence and even rarer are the hybrid tumors of central hemangiomas with odontogenic tumors such as ameloblastomas. This paper reports a case of one such hybrid tumor in a middle aged adult clinical presenting as a mandibular swelling with indistinct mixed radiographic presentation and histopathologically comprising of intimately associated hemangiomatous vascular channels and typical ameloblastic areas. To the authors' knowledge this is the sixth case of such a hemangiomatous ameloblastoma which has been reported till date. PMID:24765404

Both were notable for coexisting hemangiomas in the close vicinity. To the best of our knowledge we are reporting these two variants of IPPP with the associated neighboring hemangiomas for the first time in Indian dermatologic literature. We suggest that this presentation may be a part of one of the syndromes that comprise anorectal malformations with hemangiomas like PELVIS syndrome and others mentioned in the table. PMID:24470664

    We present the case of an 18-year-old male patient that was referred to our gastrenterology department with history of intermittent painless hematochezia since childhood. During such instances, he was diagnosed with bowel intussusception, eosinophilic gastroenteritis and inflammatory bowel disease at 4, 6 and 8 years old, respectively. He underwent treatment with 5-aminosalicylic acid for two years, without improvement of symptoms. He was then lost to follow-up until our observation. His physical examination was unremarkable except for digital rectal examination which found a nodular compressible mass by the palpating finger. Blood tests revealed a mild iron deficiency anemia. The colonoscopy showed an extended reddish and bluish multinodular submucosal mass in the rectum, suggesting diffuse cavernous hemangioma of the rectum (DHCR). The Magnetic Resonance Imaging, showed diffuse thickening of the entire rectum extending into the distal sigmoid with the mesorectum revealing multiple serpiginous structures, corresponding to abnormal blood vessels. After discussion, we considered to perform a sphincter-sparing procedure, namely pull through transection and coloanal anastomosis. However, intervention was ruled out by the patient because of his fear of anal incontinence and permanent colostomy. We adopted a conservative strategy with clinical surveillance and iron supplementation. At the present, the patient remains with intermittent rectal bleeding, referring poor quality of life due to his ongoing symptoms. This is a rare case of DHCR. Despite of being a benign disease, the management of DHCR requires a sphincter mucosectomy and pull-through coloanal sleeve anastomosis which has become the first-line procedure. The surgical outcomes are non-expectable in 32% with permanent sphincter lesion or with incomplete DHCR removal. As in this case, the surgeons or patients refusal to perform the intervention is common which represents a challenge to the clinical follow

    The aim of this study was to evaluate the choroidal thickness (CT) changes associated with visual function following photodynamic therapy (PDT) for a diffuse choroidal hemangioma in Sturge–Weber syndrome. We report a case of Sturge–Weber syndrome and symptomatic serous retinal detachment (SRD) with diffuse choroidal hemangioma treated with PDT. Visual acuity (VA), macular sensitivity measured by means of MP1 microperimeter (Nidek Technologies, Padova, Italy), retinal and CT, measured by means of enhanced depth optical coherence tomography (EDI–OCT, Spectralis, Heidelberg Engineering, Heidelberg, Germany) were analyzed at baseline, 3 and 12 months follow-up.After the PDT VA and macular sensitivity improved.The OCT examination showed the resolution of SRD. The choroid was measured after PDT using EDI–OCT. At baseline, the subfoveal CT showed a progressive thickness reduction from 251 to 83 lm during follow-up. To our knowledge, this is the first report of CT changes after PDT for a diffuse choroidal hemangioma in Sturge–Weber syndrome in a longterm follow-up. The CT measurement represents a potential parameter to better follow choroidal hemangiomas and their response to treatment. However,the long-term choroidal changes should be carefully taken into account. PMID:24658736

    Adult pancreatic hemangioma is a rare disease. We presented a case of a woman with pancreatic tail mass mimicking a distant metastasis from the kidney. A 68-year-old woman was found with a left kidney mass on medical checkup. Computed tomography scan showed a 4.3 cm-sized mass in the left kidney, suggesting renal cell carcinoma (RCC), and a strongly enhancing tiny nodule in the pancreatic tail. We could not rule the possibility of RCC metastasis, hence, surgical resection of the pancreatic mass simultaneously with radical nephrectomy for RCC was conducted. Gross pathologic examination revealed hemangioma. Immunohistochemistry revealed that the tumor was positive for CD34, CD31 and factor VIII-related antigen. There were no significant postoperative events, and the patient was discharged on postoperative day 7 without any complications. Treatment strategies for pancreatic hemangioma have not been established. To our knowledge, this was the first case report of asymptomatic pancreatic hemangioma. In previous literature, treatment differed on a case-by-case basis, ranging from observation to surgical resection. The most important factor in deciding whether to perform surgery is possibly risk-benefit effectiveness; however, tumor location, patient symptoms, and other factors are also important.

    Multifocal hepatic hemangioma (MHH) is a benign hepatic tumor that is commonly diagnosed in children with multiple cutaneous infantile hemangiomas (IHs). We present a review of all children with MHH at our institutions. Of the 42 patients, the median age at presentation of MHH was 2.5 months. Thirty-six (85.7%) patients had cutaneous IHs. Twelve (28.6%) patients were symptomatic at presentation. There was no significant association between the number of hepatic hemangiomas and the number of cutaneous IHs. Fourteen (33.3%) patients received some form of treatment for hepatic hemangiomas. The most common type of treatment was oral prednisone in 8 patients, followed by oral propranolol in 6 patients. Two patients were totally resistant to prednisone treatment. They died from congestive heart failure or respiratory distress and coagulopathy. Two patients with problematic facial IH were treated with intralesional triamcinolone injection. The remaining 26 patients were managed with imaging surveillance. On follow-up, all of the survivors had a favorable outcome. Our study suggests that the clinical features of MHH are variable. Our data emphasize the treatment strategy that aggressive treatment is indicated in symptomatic or progressive MHHs, whereas observation management of asymptomatic patients with a few small lesions is safe and appropriate.

    Infantile hemangiomas affect about 5% (3%-8%) of the population, showing a predilection for the face. After a phase of rapid enlargement between the 3rd and the 9th month of life, 70% regress by the age of six after a period of stability. 43%-60% of the children with eye lid hemangiomas develop strabismic, anisometropic, or deprivation amblyopia. Previous studies found the majority of cases resulting from anisometropia (especially asymmetric astigmatism) rather than strabism or occlusion of the visual axis. Several methods of treatment--surgical excision, irradiation, sclerosing agents, systemic steroids, ligation, cryotherapy--have been used but all with a risk of local or systemic complications. Local injections of steroids are a simple method of therapy with a high rate of resolution of hemangiomas, but still with a high degree of bad visual output because of persistent astigmatism. In four children with asymmetric astigmatism (axis of astigmatism towards the hemangioma) in which the injection was given at the beginning of the phase of enlargement, amblyopia could be avoided by preventing corneal steepening from becoming permanent.

    Angiogenesis is a major factor in the development of benign, inflammatory, and malignant processes of the skin. Endothelial cells are the effector cells of angiogenesis, and understanding their response to growth factors and inhibitors is critical to understanding the pathogenesis and treatment of skin disease. Hemangiomas, benign tumors of endothelial cells, represent the most common tumor of childhood. In our previous studies, we have found that tumor vasculature in human solid tumors expresses similarities in signaling to that of hemangiomas, making the knowledge of signaling in hemangiomas widely applicable. These similarities include expression of reactive oxygen, NFkB and akt in tumor vasculature. Furthermore, we have studied malignant vascular tumors, including hemangioendothelioma and angiosarcoma and have shown distinct signaling abnormalities in these tumors. The incidence of these tumors is expected to rise due to environmental insults, such as radiation and lumpectomy for breast cancer, dietary and industrial carcinogens (hepatic angiosarcoma), and chronic ultraviolet exposure and potential Agent Orange exposure. I hypothesize that hemangiomas, angiosarcomas, and vascular malformations represent the extremes of signaling abnormalities seen in pathogenic angiogenesis. PMID:19925405

    A 32-year old man with Sturge-Weber syndrome, a rare congenital disease of multiple angiomatous lesions including cervical cortex, face, oral soft tissues, larynx and trachea, underwent the excision of a back lipoma. His hemangioma which extended into the region of the right ophthalmic nerve and superior maxillary nerve is extremely large. He also had mental retardation and epilepsy. No apparent hemangioma was found in his oral cavity, pharynxes, larynx and trachea by preoperative exam. His hemangioma made it difficult to cover his mouth and nose by usual face mask. Though we first considered awake intubation, he was difficult to obey our command. So we searched for the face mask covering his nose and mouth without pressing his facial angioma. Finally, we discovered the full-face mask for NIPPV. After induction with propofol, we confirmed the perfect mask fit, and ventilation by two-person method was effective. Then we administered rocuronium and fentanyl, and intubated without difficulty. The patient was maintained by sevoflurane. He was hemodynamically stable. He was extubated without bleeding and respiratory problems. We experienced general anesthesia of a patient with Sturge-Weber syndrome who had a giant facial hemangioma. With full-face NIPPV mask we safely induced general anesthesia. PMID:24979867

    Introduction Giant cavernous hemangiomas are the most common tumors of the liver, ocurring in up to 20% of the general population. Given their benign course, asymptomatic nature and slow growth rate, treatment is rarely indicated. The case presented herein is unique as it describes an uncommon presentation of this common tumor and the circumstances in which surgical treatment is beneficial. Presentation of case We present a case of a 66 year-old patient with prostate cancer referred for evaluation of a massive 37 cm giant liver hemangioma, extending into the pelvis and in the planned field of radiation for prostate cancer, exhibiting rapid growth, and associated with significant symptomatology. Given these clinical characteristics, the patient was offered surgery and underwent a left trisectionectomy with an uneventful recovery. The patient's symptoms resolved and he was able to complete radiation to the pelvis. Discussion In the context of an unusual presentation, this case presentation reviews the typical clinical and imaging characteristics of giant liver hemangiomas and expands on the current indications for treatment, emphasizing the role of enucleation and resection for patients meeting appropriate indications. Conclusion Although liver hemangiomas are extremely common, surgical treatment is rarely required. With appropriate indications, and when enucleation is not feasible or ideal, major liver resection is a safe alternative approach with excellent outcomes when performed in the right setting.

    A 48-year-old man presented with a 2-week history of progressive gait disturbance. Neurological examinations showed mild weakness in his lower extremities and depreciation of deep sensation. Magnetic resonance (MR) imaging showed an intradural extramedullary enhanced lesion at the levels of the T10 and T11 vertebrae. Laminectomy of the T10 and T11 vertebrae was performed, and the vascular tumor on the spinal cord surface was completely resected. Histological analysis indicated that the lesion was a capillary hemangioma with an elevated proliferative index. Postoperatively, the patient showed rapid motor and sensory improvement. However, 6 months after the operation, MR imaging showed regrowth of the tumor although the clinical symptoms of the patient had not deteriorated. The patient has shown no tumor regrowth 9 years after the second operation. Capillary hemangiomas in the skin and soft tissues are often associated with high proliferative activity, and recurrence/regrowth is not infrequent. On the other hand, recurrence/regrowth of capillary hemangioma in the neuraxis after tumor resection has rarely been observed, even in cases of incomplete resection. The present case illustrates the treatment of recurrent capillary hemangioma of the spinal cord. PMID:23006883

    Cherry hemangiomas are common vascular proliferative lesions that can be concerning from a cosmetic perspective. Laser therapy is often used to eradicate cherry hemangiomas, but some lesions require multiple treatments or do not resolve at all. The suboptimal response to laser treatment may be due to limitations in penetration depth by vascular lasers such as the pulsed dye laser. Optical coherence tomography is a low-energy, light-based imaging device that can evaluate the depth and extent of vascular lesions such as cherry hemangiomas by allowing visualization of tissue structure and blood vessel architecture, which cannot be appreciated by clinical or dermatoscopic examination alone. We present optical coherence tomography images of a cherry hemangioma to demonstrate the precision and resolution of this imaging modality. Optical coherence tomography provides valuable information that has the potential to predict response to laser therapy without unnecessary attempts. Future prospective studies will determine its value for this purpose.

    Hemangiomas of the ovary are rare with a majority described as individual reports of unusual clinical presentations or morphologic findings. Both the expected and unexpected pathologic features of these tumors in the ovary are not well detailed. Therefore, we collected the largest series of ovarian hemangiomas to comprehensively define their clinicopathologic associations and examine the significance of hormone receptors in their pathogenesis. In addition, a novel EWSR1-NFATC1 fusion has recently been described in a case of hemangioma of bone. To our knowledge, EWSR1 rearrangement has not been evaluated in hemangiomas of other sites or in a case series. Accordingly, we used fluorescence in situ hybridization to investigate EWSR1 status in a majority of our cases. Clinical presentation was variable and dependent on tumor size. Patient age ranged 48 to 87 yr (median 63 yr). Tumors involved the right (n=6) and left (n=3) ovaries with laterality unknown in 1 case, and size ranged from 0.2 to 5.0 cm (median 1.0 cm). Three of 4 radiologic reports were either equivocal or could not exclude malignancy. Seven cases were of the cavernous type and 3 were mixed cavernous and capillary type. All lesions formed a single discrete, circumscribed mass that displaced the surrounding cortical stroma. The cavernous type showed dilated, thin-walled vessels and vascular thrombi, some of which were associated with dystrophic calcification. In addition to cavernous morphology, the mixed form exhibited features of capillary hemangioma such as lobulated growth of capillary-sized vascular spaces that lacked atypia or multilayering and were linked to a larger feeding vessel. Each tumor expressed CD31, CD34, FLI-1, ERG, but not D240. The hemangioma stromal cells, but not endothelium, expressed estrogen and progesterone receptors in every case. Stromal luteinization was seen in 2 cases. Follow-up ranged 1 to 139 mo and all patients were disease free. All cases were negative for EWSR1

    During the last six years we have developed a new CO2 laser technique for the treatment of symptomatic oral cavity hemangioma. Our new technique, named 'laser encircling technique', has especially succeeded during hemangioma buccal maxillary surgeries. The treatment consisted in the application of a line of points of CO2 laser circling the lesion. Depending on the position and size of the lesion, we used from 0.4 to 4.0 Joules/mm2 laser energy density per pulse, causing reduction in the size of the lesion throughout the sclerosis of nutritional vessels which led to reduction in size, volume and color of the hemangiomas with no significant bleeding or inflammatory reaction. In this work forty male and female patients, twelve to fifty years old, presenting medium to small size hemangiomas situated in different sites of the oral cavity such as the tongue, mouth vestibule, pharynx, tonsil area and lips were treated by the procedure described above. The number of laser applications was defined by the peculiarities of each case, varying form 3 to 6 sessions at 4 week intervals, always under local or topic anesthesia. The patients complained about minimal posit operative discomfort and had good cicatrix evolution. The good results achieved by this technique lead to the conclusion that CO2 laser for these types of hemangioma is an efficient and very secure method of treatment. An important aspect of our technique is the fact that using relatively low laser power we do not perform real surgery but a less aggressive alternative of treatment.

    Purpose: The aim of this study was to compare, on a retrospective basis, the results of therapy in patients with uveal hemangioma treated with photon or proton irradiation at a single center. Methods and Materials: From 1993 to 2002 a total of 44 patients were treated. Until 1998 radiotherapy was given with 6 MV photons in standard fractionation of 2.0 Gy 5 times per week. In 1998 proton therapy became available and was used since then. A dose of 20 to 22.5 Cobalt Gray Equivalent (CGE) 68 MeV protons was given on 4 consecutive days. Progressive symptoms or deterioration of vision were the indications for therapy. Results: Of the 44 patients treated, 36 had circumscribed choroidal hemangiomas and 8 had diffuse choroidal hemangiomas (DCH) and Sturge-Weber syndrome. Of the patients, 19 were treated with photons with a total dose in the range of 16 to 30 Gy. A total of 25 patients were irradiated with protons. All patients with DCH but 1 were treated with photons. Stabilization of visual acuity was achieved in 93.2% of all patients. Tumor thickness decreased in 95.4% and retinal detachment resolved in 92.9%. Late effects, although generally mild or moderate, were frequently detected. In all, 40.9% showed radiation-induced optic neuropathy, maximum Grade I. Retinopathy was found in 29.5% of cases, but only 1 patient experienced more than Grade II severity. Retinopathy and radiation-induced optic neuropathy were reversible in some of the patients and in some resolved completely. No differences could be detected between patients with circumscribed choroidal hemangiomas treated with protons and photons. Treatment was less effective in DCH patients (75%). Conclusions: Radiotherapy is effective in treating choroidal hemangiomas with respect to visual acuity and tumor thickness but a benefit of proton therapy could not be detected. Side effects are moderate but careful monitoring for side effects should be part of the follow-up procedures.

    For the first time the complex correlation and fractal analysis was used for the investigation of microscopic images of both tissue images and hemangioma liquids.

    For the first time the complex correlation and fractal analysis was used for the investigation of microscopic images of both tissue images and hemangioma liquids. It was proposed a physical model of description of phase distributions formation of coherent radiation, which was transformed by optical anisotropic biological structures. The phase maps of laser radiation in the boundary diffraction zone were used as the main information parameter. The results of investigating the interrelation between the values of correlation (correlation area, asymmetry coefficient and autocorrelation function excess) and fractal (dispersion of logarithmic dependencies of power spectra) parameters are presented.

    Sclerosing hemangioma (pneumocytoma) is a rare benign lung tumor with uncertain histogenesis but characteristic histology. Reports of the cytopathology of this tumor are even rarer with only a handful of cases in the literature--many of these incorrectly diagnosed by cytology initially. Herein, we describe a case of sclerosing hemangioma diagnosed prima facie by fine-needle aspiration cytology. A cell block preparation with accompanying immunohistochemistry was instrumental in making the diagnosis. A review of the literature is also presented. PMID:22645055

    Purpose: Cavernous sinus hemangioma is a rare vascular tumor. The direct microsurgical approach usually results in massive hemorrhage. Although radiosurgery plays an important role in managing cavernous sinus hemangiomas as a treatment alternative to microsurgery, the potential for increased toxicity with single-session treatment of large tumors is a concern. The purpose of this study was to assess the efficacy of hypofractionated stereotactic radiotherapy in patients with large cavernous sinus hemangiomas. Methods: Fourteen patients with large (volume >20 cm{sup 3}) cavernous sinus hemangiomas were enrolled in a prospective Phase II study between December 2007 and December 2010. The hypofractionated stereotactic radiotherapy dose was 21 Gy delivered in 3 fractions. Results: After a mean follow-up of 15 months (range, 6-36 months), the magnetic resonance images showed a mean of 77% tumor volume reduction (range, 44-99%). Among the 6 patients with cranial nerve impairments before hypofractionated stereotactic radiotherapy, 1 achieved symptomatic complete resolution and 5 had improvement. No radiotherapy-related complications were observed during follow-up. Conclusion: Our current experience, though preliminary, substantiates the role of hypofractionated stereotactic radiotherapy for large cavernous sinus hemangiomas. Although a longer and more extensive follow-up is needed, hypofractionated stereotactic radiotherapy of 21 Gy delivered in 3 fractions is effective in reducing the tumor volume without causing any new deficits and can be considered as a treatment modality for large cavernous sinus hemangiomas.

    Introduction Hepatic sclerosing hemangioma is a very rare benign tumor, characterized by fibrosis and hyalinization occurring in association with degeneration of a hepatic cavernous hemangioma. We report here a rare case of multiple hepatic sclerosing hemangioma mimicking metastatic liver tumor that was successfully treated using laparoscopic surgery. Presentation of case A 67-year-old woman with multiple liver tumors underwent single-incision laparoscopic sigmoidectomy under a diagnosis of advanced sigmoid cancer with multiple liver metastases. Examination of surgical specimens of sigmoid colon revealed moderately differentiated adenocarcinoma invading the serosa, and no lymph node metastases. Serum levels of carcinoembryonic antigen and carbohydrate antigen 19-9 remained within normal limits throughout the course. Two months after sigmoidectomy, the patient underwent laparoscopic partial hepatectomy of S1 and S6 of the liver and cholecystectomy. Histopathological examination showed that the tumors mainly comprised hyalinized tissue and collagen fibers with sporadic vascular spaces on hematoxylin and eosin-stained sections, yielding a diagnosis of multiple hepatic sclerosing hemangioma. No evidence of recurrence has been seen as of 21 months postoperatively. Discussion Differentiating multiple sclerosing hemangiomas from metastatic liver tumors was quite difficult because the radiological findings were closely compatible with liver metastases. Laroscopic hepatectomy provided less blood loss, a shorter duration of hospitalization, and good cosmetic results. Conclusion Sclerosing hemangioma should be included among the differential diagnoses of multiple liver tumors in patients with colorectal cancer. Laparoscopic hepatectomy is useful for diagnostic therapy for undiagnosed multiple liver tumors. PMID:25679307

    BACKGROUND Cardiac tumors are quite rare, and differential diagnosis of them is challenging. CASE REPORT A young lady with a history of palpitations, dyspnea, and fatigue was proven by transthoracic echocardiography and cardiac magnetic resonance imaging to have a mobile left ventricular mass with rounded contour attached to the mid-part of the interventricular septum. The mass was approached via a posterior inter-atrial approach to avoid left ventriculotomy and provide adequate exposure to completely excise the tumor and control its pedicle with minimal cardiac trauma. Histological examination of the mass was diagnostic of capillary and sinusoidal hemangioma. CONCLUSIONS Complete excision of cardiac hemangioma is recommended once it is diagnosed, for histopathologic diagnosis and because of the possibility of serious complications. PMID:27384944

    Background: Although rare, primary calvarial hemangioma is a known entity, surgical excision of which usually results in massive blood loss. Successful total excision of such a lesion remains a challenge, especially when these are in close vicinity of major venous sinuses. Case Description: Authors describe a rare case of intra-osseous occipital cavernoma along with radiological findings in a 50-year-old male. En bloc resection of tumor was performed using a high-speed pneumatic drill and no recurrence was noted at 6 months of follow-up. Conclusion: Intra-osseous cavernous hemangiomas have classical radiological features and can be excised completely, even when lying above major venous drainage channels like torcula. PMID:27308094

    Rapidly involuting congenital hemangiomas (RICH) are the commonest variety of congenital hemangioma, often diagnosed antenatally as high-flow arteriovenous shunts causing hemodynamic compromise to the fetus. The postnatal management of such patients is often challenging. We present the case of an infant boy who was delivered prematurely at 29 weeks of gestation due to fetal compromise by a RICH, with features of high-output cardiac failure and major systemic hemodynamic steal from peripheral organs. Two early angioembolizations were required to manage his high-output cardiac failure. To our knowledge, this infant is the smallest and earliest newborn case of successful angioembolization for a complex, life-threatening vascular anomaly. We discuss the interventional dilemmas regarding the optimal timing of delivery and early embolization. PMID:26929881

    The patient was a 51-year-old man who visited the hospital with swelling of the anterior chest. Chest computed tomography detected a tumor developing from the anterior mediastinum to the anterior chest wall. There was weak contrast enhancement inside the tumor, and calcification was observed in the central region. A soft tumor with an obscure border and that adhered to the back of the left sternum was surgically removed with thymic fat including the region of the chest wall that had been penetrated by the tumor. The tumor measured 30 x 25 mm, and a phlebolith was observed in the center. The pathological tissue was diagnosed to be a cavernous hemangioma, and there were no malignant findings in the endothelial cells. Mediastinal hemangioma should therefore be kept in mind during an evaluation of mediastinal tumors, and one must also take into account the effect on the surrounding organs. PMID:17491358

    Hemangiomas, vascular malformations, and varices are common benign vascular lesions in the head and neck region. They can occur in the mouth and primarily affect the lips, tongue, buccal mucosa, and palate. The main types of treatments are surgery and intralesional injection of sclerosant agents. However, other therapies have been considered, such as systemic corticosteroids, laser therapy, interferon a, and cryotherapy. Currently, sclerotherapy is employed largely because of its efficiency and ability to conserve the surrounded tissues. Surgery can be used exclusively or associated with sclerotherapy in lesions that do not show complete resolution. This article describes the cases of two patients with oral hemangiomas that were submitted to sclerotherapy with ethanolamine oleate. Although an important decrease was detected after seven applications in both cases, surgical resection of the residual lesion was performed to achieve optimal results. PMID:21903533

SPIE 5863, 107-115 (2005), Russian Federation patent No.2290228 of.27.12.06) to treatment of hemangiomas in children are presented and analyzed in this work. From 2001 the technology was applied to about 1500 children with more than 2000 hemangiomas. Majority of them were complicated ones: belong to cavernous or combined types or (and) were localized on problem places: on face near eyes, nose, and lips, on auricles, on perineum near anus and genitals, in respiratory and gastrointestinal tracts. Diode laser with wavelength 920, 970, and 1060 nm at distant and interstitial irradiation were applied. In case of need there applied endoscopes. Excellent and good results have been achieved in 94% cases; there was a significant improvement in the rest cases.

    Percutaneous intervention is one treatment option for symptomatic hepatic hemangioma in infants. We report the case of a newborn (birth weight 4060 g) with a large hepatic cavernous hemangioma, which presented early with high cardiac output failure due to arteriovenous shunting and signs of incipient Kasabach-Merritt syndrome. We performed a successful superselective transcatheter coil embolization of three feeding arteries on the seventh day of life. Because of remaining diffuse very small arteries causing a relevant residual shunt, additional occlusion of the three main draining veins was necessary with three Amplatzer vascular plugs. Cardiac failure resolved immediately. Without any additional therapy the large venous cavities disappeared within the following months. The tumor continues to regress in size 8 months after the intervention.

    Urethral hemangiomas are rare and benign tumors, probably originating from a unipotent angioblastic stem cell. They can vary in size and the clinical appearance can range from asymptomatic lesions to urethral bleeding or gross hematuria. We present the case of an 18-year-old male, with a history of urethral bleeding. Cystourethoscopy revealed a solitary bulging mass into the lumen, about 6 cm far from the external meatus. Doppler study confirmed that the lesion was in communication with the vessels of the left spongious body. The patient underwent surgical removal of the lesion. The post-procedure Doppler study revealed an inflammation-based remodeling of the spongoius urethra and the absence of the previous vascular connection. At the time of publication the patient is still symptom-free. The surgical removal of urethral hemangiomas is by far the technique of choice for treating such lesions in young patients, thus avoiding side effects of LASER treatments. PMID:22760936

    We describe a 3 1/2-year-old boy with the Klippel-Trenaunay and Sturge-Weber syndromes. The child had congenital superficial capillary hemangiomas, congenital glaucoma and mild hydrocephalus. During the first year of life he experienced intermittent hematuria. When he was 3 years old he presented with seizures and left hemihypertrophy first was noted. Several months later radiological examination of a large abdominal mass demonstrated its origin to be in the right kidney. Radical nephrectomy documented the presence of renal hemangioma with complicating perirenal hematoma. A double inferior vena cava was another unexpected surgical finding that complicated the course of this patient. All of these unusual features in these rare syndromes with their clinical, pathogenetic and therapeutic implications are discussed. The differential diagnosis of renal masses in these syndromes also is presented. PMID:3016342

    BACKGROUND: Infantile hemangioma is the most common benign, self-limiting tumour of childhood. Treatment is reserved for hemangiomas that obstruct vital structures or cause significant disfigurement. Traditionally, corticosteroids have been the medical treatment of choice. Since 2008, however, propranolol has been rapidly adopted as an effective pharmacological treatment for infantile hemangioma. Published data regarding the long-term side effects of propranolol are currently lacking. OBJECTIVE: To describe the long-term effects of propranolol and corticosteroids on anthropometric measurements (height, body mass index [BMI]) and blood pressure in children. METHODS: A prospective database analysis of all infantile hemangioma patient visits to the pediatric vascular abnormality clinic at the authors’ institution between October 2007 and February 2012 was performed. Anthropometric measures (height and BMI) and blood pressure were analyzed. RESULTS: A total of 290 visits (119 patients) to the pediatric vascular abnormality clinic were reviewed. Of these, 18 patients received medical treatment and their anthropometry was analyzed. BMI percentile increased significantly in patients treated with corticosteroids (P=0.0039). Corticosteroid treatment also resulted in a significant decrease in height percentile (P=0.0078). Anthropometric measures did not cross percentiles in children treated with propranolol. A significant decrease in systolic blood pressure was noted in the propranolol group (P=0.03), but no hypotensive values were recorded. Median treatment duration was significantly longer when patients received propranolol (372 versus 133 days; P=0.0033). CONCLUSION: Propranolol for the treatment of infantile vascular abnormalities does not share the unfavourable effects on patient anthropometry that corticosteroids exhibit; however, a longer duration of therapy is required.

    Although hemangiomas are the most common vascular tumors of the liver in infancy, data regarding hypothyroidism and heart failure related to hepatic hemangiomas are limited. Here, we present a 15- day -old girl who presented with prolonged jaundice at the age of 15 days. Because her TSH level was found to be 74 μIU/mL, she was initially diagnosed with congenital hypothyroidism and L-Thyroxine replacement therapy was initiated. On follow-up examination performed two months later, it was observed that her TSH level was not suppressed and a mass was noticed in the right upper abdomen on physical examination. Abdominal ultrasonography revealed multiple masses with sizes of about 3-3,5 cm covering the whole liver. When evaluated with clinical and radiological appearance, oral methylprednisolone at a dose of 5 mg/kg/day and propranolol at a dose of 2 mg/kg were initiated with a diagnosis of hepatic hemagioma/hemangioendothelioma. Consumptive hypothyroidism due to hepatic hemangioma and congestive heart failure were considered in the patient who had findings of heart failure. The dose of L-Thyroxine was increased 2-fold. The patient received intensive care treatment for severe heart failure. Because his findings resolved, he was started to be followed up with propranolol, steroid and L-Thyroxine treatment.

    The aim of this study is to describe vision loss caused by central retinal artery and posterior ciliary artery occlusion as a consequence of sclerotherapy with a polidocanol injection to a glabellar hemangioma. An 18-year-old man underwent direct injection with a 23-gauge needle of 1 mL of a polidocanol-carbon dioxide emulsion into the glabellar subcutaneous hemangioma under ultrasound visualization of the needle tip by radiologists. He developed lid swelling the next day, and 3 days later at referral, the visual acuity in the left eye was no light perception. Funduscopy revealed central retinal artery occlusion and fluorescein angiography disclosed no perfusion at all in the left fundus, indicating concurrent posterior ciliary artery occlusion. The patient also showed mydriasis, blepharoptosis, and total external ophthalmoplegia on the left side. Magnetic resonance imaging demonstrated the swollen medial rectus muscle. In a month, blepharoptosis and ophthalmoplegia resolved but the visual acuity remained no light perception. Sclerosing therapy for facial hemangioma may develop a severe complication such as permanent visual loss.

    Dubin-Johnson syndrome (DJS) is a rare autosomal recessive inheritance disorder of bilirubin metabolism. Herein we reported a complicated but interesting case which is readily resulted in misdiagnosis or an indefinite diagnosis, and this is the first reported familial case of DJS with multiple liver cavernous hemangiomas. A 49-year-old man was referred to our hospital for jaundice and multiple low-density liver masses. Extensive laboratory investigations showed conjugated hyperbilirubinaemia and positive urine bilirubin. Microscopically, lesions were composed of blood-filled vascular channels of various sizes lined by a single layer of flat endothelial cells supported by fibrous tissue. Coarse brown granules presented in the hepatocytes of the liver lobules locating beside the tumor, particularly in the centrilobular hepatocytes, and the granules showed blue-green with Schmorl’s reaction lipofuscin staining. Interestingly, one of the patient’s six siblings (female) shared the same condition with him. The relationship between DJS and hemangiomas remains unclear, and it might be contributed to some hereditary factors, or probably occurred simultaneously by chance. It was certified that the true reason for the long-term unclear jaundice was DJS, which was presumed clinically to be caused by bile excretion obstacles associated with the hemangiomas. Liver biopsy and histochemical stain may be helpful to identify the reason of jaundice and avoid misdiagnosis or an indefinite diagnosis. PMID:24228133

    The management of infantile hemangiomas remains a subject of controversy. The purpose of this study was to investigate the indications and treatment results of intralesional injection of pingyangmycin for treatment of infantile hemangiomas. In a prospective study of 66 patients, the effectiveness of intralesional injection of pingyangmycin was evaluated and documented. The lesions were all located in the oral and maxillofacial regions. The smallest lesion was 1.0 cm × 0.7 cm and the largest was 4.6 cm × 3.8 cm. Amongst the 66 infants who underwent sclerotherapy with pingyangmycin, cure was obtained in 74% (49/66) of patients, marked improvement of the treated lesion occurred in 14% (9/66), improvement occurred in 12% (8/66), and a lack of response was not observed in any patient. All patients were regularly followed up for 1-4 years following pingyangmycin treatment, and they demonstrated the same good results over this time. Intralesional injection of pingyangmycin was a reliable and effective therapeutic choice for infantile oral and maxillofacial hemangiomas, as it shortened the involution time and decreased the influence induced by these potentially countenance-influenced tumours with few complications.

    Commercial spaceflight participants are typically older than traditional astronauts and often have medical conditions that make medical certification for flight difficult. This case report considers a 43-yr-old spaceflight participant who planned a short-duration Soyuz flight to the International Space Station (ISS). While he participated in many hazardous activities such as parachuting, hang gliding, scuba diving, Antarctic and jungle exploration, and deep sea submersible operations, he knew that several of his medical conditions precluded serving as a career astronaut. At the time of his initial spaceflight prescreen examination, he was known to have previous bilateral photorefractive keratectomy (PRK) for myopia and a cross-fused left ectopic kidney that would be disqualifying for a career astronaut. During the evaluation for the left single cross-fused ectopic kidney, a giant hepatic hemangioma was also discovered. In order to medically qualify for flight, the giant hepatic hemangioma was surgically removed. This case summary investigat*es the implications of a single cross-fused left ectopic kidney and the decision process and treatment implications for spaceflight medical certification in an individual with an asymptomatic giant hepatic hemangioma.

    A 20-year-old female patient presented with two masses located in the left liver. In this patient, a computed tomography (CT) scan revealed a hypodense mass and a second well-defined mass with a calcified nodule in the left hepatic lobe. No enhancements were apparent in or around the masses. A laparotomy was performed due to the patient’s symptoms, namely, the atypical CT findings and a risk of rupture of the subcapsular lesion. The operation revealed two masses in the left hepatic lobe and a left liver resection was subsequently performed. One of the masses involved segment III and the other mass was located in segment IV. The histopathologic findings supported a diagnosis of collagenous nodule mixed simple cyst and hemangioma. A diagnosis of collagenous nodule mixed simple hepatic cyst is extremely rare and radiologically mimics a teratoma, hepatolithiasis, parasitic cyst, or hemangioma. Although hepatic hemangiomas are the most common benign tumors found in the liver, the present case showed atypical radiographic features. PMID:25892897

    OBJECT Cavernous hemangioma of the internal auditory canal (IAC) is an extremely rare type of tumor, and only 50 cases have been reported in the literature prior to this study. The aim in this study was to describe the symptomatology, radiological features, and surgical outcomes for patients with cavernous hemangioma of the IAC and to discuss the diagnostic criteria and treatment strategy for the disease. METHODS The study included 6 patients with cavernous hemangioma of the IAC. All patients presented with sensorineural hearing loss and tinnitus, and 2 also suffered from vertigo. Five patients reported a history of facial symptoms with hemispasm or palsy: 3 had progressive facial weakness, 1 had a hemispasm, and 1 had a history of recovery from sudden facial paresis. All patients underwent CT and MRI to rule out intracanalicular vestibular schwannomas and facial nerve neuromas. Five patients had their tumors surgically removed, while 1 patient, who did not have facial problems, was followed up with a wait-and-scan approach. RESULTS All patients had a presurgical diagnosis of cavernous hemangioma of the IAC, which was confirmed pathologically in the 5 patients who underwent surgical removal of the tumor. The translabyrinthine approach was used to remove the tumor in 4 patients, while the middle cranial fossa approach was used in the 1 patient who still had functional hearing. Tumors adhered to cranial nerves VII and/or VIII and were difficult to dissect from nerve sheaths during surgeries. Complete hearing loss occurred in all 5 patients. In 3 patients, the facial nerve could not be separated from the tumor, and primary end-to-end anastomosis was performed. Intact facial nerve preservation was achieved in 2 patients. Patients were followed up for at least 1 year after treatment, and MRI showed no evidence of tumor regrowth. All patients experienced some level of recovery in facial nerve function. CONCLUSIONS Cavernous hemangioma of the IAC can be diagnosed

    Several vascular lesions are related to the lip area. There is no universally accepted protocol for the treatment of hemangiomas and vascular malformations. In the oral cavity, high-power lasers represent an excellent therapeutic option for this type of lesion. Their coagulative properties allow for the performance of procedures without the risk of bleeding, which promotes a better healing pattern and a differentiated postoperative appearance. This study describes three cases of lip hemangioma treated with forced dehydration with induced photocoagulation (FDIP) via diode laser. All the reported cases were followed up until complete healing of the operated area had total remission of lesions, with no complications or adverse effects. The findings of the present study suggest that FDIP is effective and useful in the treatment of hemangiomas in the oral cavity. Laser treatment of these lesions prevents their recurrence and is well tolerated by patients. PMID:25577591

Additionally, three similar lesions were found on the right side of the palate and adjoining buccogingival surfaces. The parents were particularly concerned about the explosive progression of the lesions, recurrent bleeding episodes from ulcerated areas of the cheek lesion and complete occlusion of the right eye. Following four weeks therapy with propranolol in a dose of 2 mg/kg/day, the hemangiomas rapidly regressed, the bleeding episodes ceased and the infant started opening the eye. PMID:25606481

    Sclerosing Hemangioma is a rare lung tumor with polymorphic histologic features that usually occurs in middle aged women. Based on many immunohistochemical and ultrastructural studies, it is most probably derived from undifferentiated respiratory epithelial cells. Symptoms are usually due to enlargement of the tumor and compression of the surrounding tissues. Occurrence of multiple lesions or metastasis is extremely rare although some authors consider sclerosing hemangioma as a potentially low grade malignancy tumor. It usually presents with low to moderate uptake on FDG PET imaging. We present a case of sclerosing hemangioma with strong FDG avidity on PET scan in a 41 year old lady with history of haemoptysis. A full review of the literature on this topic was performed. PMID:27222778

    We report on a case of double aneuploidy involving Down and Turner cell lines in a female child with a massive capillary hemangioma of the left orbit and mild clinical features of Down syndrome. Cytogenetic findings with G-banding revealed mosaicism in her peripheral blood, i.e. mos45,X[48]/47,XX,+21[28]/46,XX[12/47,XXX[12]. Mosaicism of such nature is rare and to our knowledge the present case is the first reported of Turner-Down double aneuploidy mosaicism associated with an orbital capillary hemangioma. An annotated bibliography of earlier reported cases with documented karyotyping is also included. PMID:11522243

    Infantile hemangiomas (IHs) are common neoplasms composed of proliferating endothelial-like cells. Despite the relative frequency of IH and the potential severity of complications, there are currently no uniform guidelines for treatment. Although propranolol has rapidly been adopted, there is significant uncertainty and divergence of opinion regarding safety monitoring, dose escalation, and its use in PHACE syndrome (PHACE = posterior fossa, hemangioma, arterial lesions, cardiac abnormalities, eye abnormalities; a cutaneous neurovascular syndrome characterized by large, segmental hemangiomas of the head and neck along with congenital anomalies of the brain, heart, eyes and/or chest wall). A consensus conference was held on December 9, 2011. The multidisciplinary team reviewed existing data on the pharmacologic properties of propranolol and all published reports pertaining to the use of propranolol in pediatric patients. Workgroups were assigned specific topics to propose protocols on the following subjects: contraindications, special populations, pretreatment evaluation, dose escalation, and monitoring. Consensus protocols were recorded during the meeting and refined after the meeting. When appropriate, protocol clarifications and revision were made and agreed upon by the group via teleconference. Because of the absence of high-quality clinical research data, evidence-based recommendations are not possible at present. However, the team agreed on a number of recommendations that arose from a review of existing evidence, including when to treat complicated IH; contraindications and pretreatment evaluation protocols; propranolol use in PHACE syndrome; formulation, target dose, and frequency of propranolol; initiation of propranolol in infants; cardiovascular monitoring; ongoing monitoring; and prevention of hypoglycemia. Where there was considerable controversy, the more conservative approach was selected. We acknowledge that the recommendations are conservative in

    Background Infantile hemangioma (IH) is the most common tumor of infancy. Hemangioma stem cells (HemSC) are a mesenchymal subpopulation isolated from IH CD133+ cells. HemSC can differentiate into endothelial and pericyte/smooth muscle cells and form vascular networks when injected in immune-deficient mice. α6-Integrin subunit has been implicated in the tumorgenicity of glioblastoma stem cells and the homing properties of hematopoietic, endothelial and mesenchymal progenitor cells. Therefore, we investigated the possible function(s) of α6-integrin in HemSC. Methods/Results We documented α6-integrin expression in IH tumor specimens and HemSC by RT-qPCR and flow cytometry. We examined the effect of blocking or silencing α6-integrin on the adhesive and proliferative properties of HemSCin vitro and the vasculogenic and homing properties of HemSCin vivo. Targeting α6-integrin in cultured HemSC inhibited adhesion to laminin but had no effect on proliferation. Vessel-forming ability in Matrigel implants and hepatic homing after intravenous delivery were significantly decreased in α6-integrin siRNA transfected HemSC. Conclusion α6-Integrin is required for HemSC adherence to laminin, vessel formation in vivo and for homing to the liver. Thus, we uncovered an important role for α6 integrin in the vasculogenic properties of HemSC. Our results suggest that α6-integrin expression on HemSC could be a new target for anti-hemangioma therapy. PMID:24022922

    Interferon-alpha (IFN-alpha) has antitumor and antiangiogenic effects. The purpose of this work was to evaluate its efficacy and safety in the treatment of infancy hemangioma and to monitor the appearance of anti-IFN antibodies in these patients. Thirty-nine children (29 girls) aged 1.5-158 months, with 19 younger than 1 year and 9 older than 5, were treated with 3 x 10(6) IU/m(2) IFN-alpha 2b, subcutaneously (s.c.) daily. Inclusion criteria were life-threatening or life-limiting hemangioma and parents' informed consent. Regression was considered if tumor size diminished by 50% or more. Of the 38 patients who completed 6 months of treatment, 27 (71.1%) had regression and 11 (28.9%) had stable disease. No patient experienced progression. Regression was more frequent (100%) among patients between 1 and 5 years old, but it was particularly important (68%) among those under 1 year old, when spontaneous regression is rare. The main side effects were the IFN-related flulike syndrome (79%), increase in serum alanine aminotransferase (ALT) (28%), anorexia (19%), and mild inflammation at the injection site (19%). There was no effect on psychomotor or physical development. On the contrary, 1 patient with neurologic symptoms improved remarkably, including seizure disappearance. Eight patients developed anti-IFN-alpha 2 neutralizing antibodies, and 7 of them responded to IFN treatment. IFN-alpha 2b is a safe and efficacious treatment of infancy hemangioma. Further work should look for other treatment schedules and ways of administration and carefully monitor anti-IFN neutralizing antibodies, which does not seem to interfere with response.

    Cavernous Hemangioma of the Bladder (CHB) is benign and rare lesions. Clinical presentation has no pathognomonic signs although gross painless hematuria is the most frequent complain. CHB is suspected by cystoscopy and radiologic findings and confirmed by pathologic examinations. Management is controversial due to the bleeding risk of this highly vascularized lesion. Partial cystectomy is the treatment of choice for surgically accessible lesions. However, it appears that small lesions could be treated using transurethral resection. Since CHB is a rare case, we report another case treated successfully with a partial cystectomy associated with an augmentation cystoplasy. PMID:26889312

    Intradural intramedullary mixed type hemangioma is a rare histotype of primary spinal cord tumors, though it can carry a severe clinical burden leading to limb dysfunction or motor and sensory disturbances. Timely intervention with radical resection is the hallmark of treatment but achieving it is not an easy task even for experienced neurosurgeons. We herein present an exemplificative case presenting with sudden paraplegia in which total resection was achieved under intraoperative neurophysiology monitoring. A thorough discussion on the operative technique and the role of neuromonitoring in allowing a safe surgical management of primary spinal cord tumors is presented. PMID:26839729

    The uptake of F-fluorocholine (FCH), a radiopharmaceutical used to study patients with prostate cancer, follow both the phosphorylcholine and acetylcholine synthesis. FCH uptake is not specific of neoplastic cells because phospholipids are a structural constituent of the membrane of all cells. Thus, PET/CT with FCH show several areas of physiologic uptake. The skeleton concentrates only mild amounts of FCH, thus a diffuse faint uptake of the radiopharmaceutical is present at a PET/CT study. Herein we present the case of a patient in which PET/CT evidenced a sharply defined vertebral "cold" area of reduced FCH uptake corresponding to a vertebral hemangioma. PMID:27124683

    The aim of this study is to compare the effect of liver enucleation with resection of a giant hemangioma proximal to the hepatic portal vascular structures. From 2008 to 2014, 53 patients with giant hemangiomas proximal to the hepatic portal vascular structures underwent surgery in our hospital by the same surgical team. The indications for surgery included a tumor size greater than 8 cm, a middle size greater than 4 cm but with abdominal pain, a rapidly increased tumor size with uncertain malignancy, or tumor rupture. Thirty-two patients (60 %) had pain only, 15 (29 %) had pain with tumor growth, 5 patients (9 %) had an uncertain diagnosis, and 1 patient (2 %) had tumor rupture. Enucleation was performed in 31 patients and liver resection was performed in 22 patients. There were no significant differences in the size of the hemangioma (13.9 ± 3.1 vs 12.3 ± 5.5 cm; P > 0.05), preoperative liver function tests, hemoglobin levels, and platelet counts between the enucleation and resection groups. The mean intraoperative blood loss was significantly less in the enucleation group compared with the resection group (350.9 ± 89.8 vs 988 ± 91.7 mL; P < 0.01), and the enucleation group had a significantly shorter mean operative time (1.7 ± 0.4 vs 2.9 ± 0.9 h; P < 0.01) and significantly shorter duration of hospital stay (9.6 ± 4.2 vs 14.7 ± 3.7 days; P < 0.05). Five patients in the resection group and only 1 patient in the enucleation group had major postoperative complications. Compared to liver resection, enucleation is safer and faster for liver hemangiomas proximal to the hepatic portal vascular structures and is associated with fewer complications. PMID:27574349

    A woman was operated on for a nonepithelial malignant tumor of the left leg and subsequently, for an epithelial carcinoma of the right breast and a borderline malignant tumor of the right ovary. She also developed a giant cavernous hemangioma that caused disseminated intravascular coagulation syndrome, which necessitated a left trisegmentectomy of the liver. Her family history suggested a hereditary predisposition to diverse malignant neoplasms, and also to giant cavernous hemangioma of the liver. Immunological evaluation disclosed selective inhibition of natural killer cell activity. Hormonal and hereditary factors are discussed in relation to the development of multiple primary tumors and giant cavernous hemangioma of the liver. PMID:2724721

    ABSTRACT Avian leukosis virus subgroup J (ALV-J) is a simple retrovirus that can cause hemangiomas and myeloid tumors in chickens and is currently a major economic problem in Asia. Here we characterize ALV-J strain PDRC-59831, a newly studied U.S. isolate of ALV-J. Five-day-old chicken embryos were infected with this virus, and the chickens developed myeloid leukosis and hemangiomas within 2 months after hatching. To investigate the mechanism of pathogenesis, we employed high-throughput sequencing to analyze proviral integration sites in these tumors. We found expanded clones with integrations in the MET gene in two of the five hemangiomas studied. This integration locus was not seen in previous work characterizing ALV-J-induced myeloid leukosis. MET is a known proto-oncogene that acts through a diverse set of signaling pathways and is involved in many neoplasms. We show that tumors harboring MET integrations exhibit strong overexpression of MET mRNA. IMPORTANCE These data suggest that ALV-J induces oncogenesis by insertional mutagenesis, and integrations in the MET oncogene can drive the overexpression of MET and contribute to the development of hemangiomas.

    Reported herein is a renal anastomosing hemangioma which developed slowly in the past four years. A 25-year-old woman was found a mass localized in the upper portion four years ago, and only slow progression in the past four years. She underwent a laparoscopic partial nephrectomy of right kidney and diagnosed as anastomosing hemangioma. On histology the vascular components of the tumor had an anastomosing pattern without well-definite margins. Immunohistochemically, only endothelial markers (CD31, CD34) were expressed on the vascular components of tumor cells. Smooth muscle actin (SMA), cytokeratin (CK), EMA and S-100 and so on were all negative in the epithelioid tumor cells. The patient was alive at 16 months after operation, without any evidence recurrence or metastasis. Anastomosing hemangioma is an extremely rare vascular neoplasm; only 23 cases were previously described until now. Our report of anastomosing hemangioma arising from the kidney with slow progression will improve the knowledge of primary vascular tumors arising in the kidney. PMID:25973131

    Introduction Cavernous hemangioma of the skull is a rare pathological diagnosis, accounting for 0.2% of bone tumors and 7% of skull tumors. Usually calvarial bone cavernous hemangioma are associated with a benign clinical course and, despite their enlargement and subsequent erosion of the surrounding bone, the inner table of the skull remains intact and the lesion is completely extracranial. Presentation of a case The authors present the unique case of a huge left frontal bone cavernous malformation with intradural extension and brain compression determining a right hemiparesis. Discussion Calvarial cavernous hemangiomas are benign tumors. They arise from vessels in the diploic space and tend to involve the outer table of the skull with relative sparing of the inner table. More extensive involvement of the inner table and extradural space is very unusual and few cases are reported in literature. To the best of our knowledge, intradural invasion of calvarial hemangioma has not been previously reported. Conclusion Our case highlights the possibility of an aggressive course of this rare benign pathology. PMID:27061482

    Hemangioma is a common disease; however, intramuscular hemangioma (IH) presenting with a pathological fracture is extremely rare. The present study reports a case of a 46-year-old male patient that suffered from IH of the right thigh, presenting with a pathological femoral fracture. The patient was initially diagnosed with a traumatic femoral fracture, and routine open reduction and internal fixation were performed at a local hospital. However, 20 days subsequent to surgery, gradual swelling and soreness around the incision were observed. The incision eventually ruptured during squatting for bowel movement, which led to extensive blood loss. Based on computed tomography (CT) and deep femoral artery arteriography, IH presenting with a pathological femoral fracture was diagnosed. The patient underwent artery embolization, from which he recovered well. At the 6-month follow-up, the femoral fracture was revealed to have healed, and a CT scan demonstrated no evidence of recurrence; however, continuous observation using CT is required in order to determine the long-term outcome. To the best of our knowledge, this is the first case of a misdiagnosed pathological femoral fracture in a patient with IH reported in the English literature. PMID:27347124

    The aim of this study was to evaluate a patient with von Hippel-Lindau (VHL) syndrome and to discuss the clinical manifestations. A 25-year-old woman presented to our clinic with blurred vision for 2 months. Best corrected visual acuity in right eye was 20/50, and fundoscopic examination revealed juxtapapillary endophytic retinal capillary hemangioma. Examination findings on left eye were normal. On optical coherence tomography, exudation was prominent on macula. History revealed cerebellar operation because of cerebellar hemangioblastoma. On abdominal ultrasonography, liver hemangiomas and pancreatic cysts were seen, confirmed by abdominal computerized tomography (CT). Abdominal CT imaging also revealed nutcracker phenomenon. Transthoracic echocardiography showed atrial septal aneurysm without shunt. The patient refused ocular treatment. At 3-month control, ophthalmic findings were the same. To our knowledge, this is the first case of VHL disease reported to be associated with nutcracker phenomenon and atrial septal aneurysm. Systemic evaluation and regular follow-up should be recommended to subjects with VHL disease. PMID:23114531

    Several years ago, a field strain retrovirus, avian hemangioma virus (AHV), was isolated from hemangioma tumors in layer hens. Sequence analysis indicated that the AHV genome contains the three prototypic retroviral genes, gag, pol, and env, and is devoid of an oncogene. In cultured endothelial cells, however, AHV induced a significant cytopathic effect through a typical apoptotic cascade. We now demonstrate that AHV also induces cell proliferation and anchorage-independent growth of BSC-1 epithelial cells and NIH-3T3 fibroblasts. This was shown by measurements of (1) cell viability, (2) DNA synthesis, (3) flow cytometry analysis of the cell DNA content, and (4) clonogenic efficiency of the infected cells. Anchorage-independent cell growth was demonstrated by colony formation in soft agar. Moreover, the AHV env gene was cloned into a MuLV-based retroviral vector, and infection of NIH-3T3 cells with this vector induced cell proliferation as well as clonogenic growth. These results suggest that AHV, which is devoid of an oncogene, is a pleiotropic activator capable of inducing either apoptosis or cellular proliferation, depending on the infected cell type.

    This study aimed to investigate the proapoptotic effects and the mechanism of action of pingyangmycin (PY) on cavernous hemangioma. The rat spleen was used as a model of cavernous hemangioma. PY was injected into the spleen and the pathological changes were observed at different time-points. Apoptosis was detected using terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay and transmission electron microscopy (TEM). The expression levels of the apoptosis-related protein, caspase-3, were determined using immunohistochemistry and image analysis. Rats injected with normal saline were the control group. Injection of normal saline did not damage rat spleens. On days 2 and 5 following PY injection, the spleens exhibited slight swelling. On days 8 and 14, atrophic changes were observed and the splenic sinus endothelial cells were damaged. At various time-points following PY injection, the apoptotic cells were observed by TEM. The TUNEL assay showed that apoptosis occurred widely among the splenic sinus endothelial cells and other splenic cells. The apoptotic rate and caspase-3 expression levels increased with prolonged PY exposure. PY induced apoptosis of splenic sinus endothelial cells through the caspase-3 activation pathway, and resulted in endothelial cell necrosis and fibroblast hyperplasia. PMID:24396428

    We aim to provide an up-to-date summary of infantile hepatic hemangioma (IHH) and its misnomers and to dialectically present the differential diagnosis of these rare entities of the liver. Eligible peer-reviewed articles on hepatic infantile hemangiomas, published between 2000 and 2015, were reviewed for this study. IHH is the most common hepatic vascular tumor in children. Once a liver mass is identified in an infant, the differential diagnosis ranges from vascular malformations to benign and malignant tumors including mesenchymal hamartoma, hepatoblastoma, metastatic neuroblastoma, so careful physical examination, imaging studies, and, if indicated, tumor markers and biopsy, are of pivotal importance to ascertain the correct diagnosis. Despite the benign nature of IHHs, some of these lesions may demand medical and/or surgical intervention, especially for multiple and diffuse IHH. Complications can include hepatomegaly, hypothyroidism and cardiac failure. Therefore, a close follow-up is required until complete involution of the lesions. We propose an algorithm to guide the physicians towards the proper management of hepatic lesions. PMID:27610342

    Vascular lesions of the head and neck region in children constitute an interesting group of lesions that benefit immensely from imaging techniques. Imaging is essential for identification, characterization, and delineation of the extent of lesion and subsequent follow-up. Infantile hemangiomas, which are vascular tumors with a specific evolution pattern, constitute a large majority of these lesions. On the other hand, there are vascular malformations, which are anomalies of the vascular system, consisting of a range of vascular tissues associated with various flow patterns. When diagnosis is clinically evident, imaging should utilize non-radiation techniques and address the issues necessary for management. Timing and interpretation of imaging methods employed in assessing childhood vascular lesion should also take into consideration the natural history so that imaging is performed to address a specific question. This review highlights the typical appearance of a hemangioma and a group of vascular malformations of the head and neck. For descriptive purpose, an attempt has been made to group lesions into specific subsites, with each one having specific clinical significance. Cases included illustrate the spectrum of the disease ranging from classical form in young children to slightly differing manifestations of the disease in adolescents and adults. The illustrations also provide a novel way of presenting image data using volume-rendering techniques of 3D data. Multi-modality team interaction and management strategies of these complex lesions are also emphasized. PMID:25161800

    We aim to provide an up-to-date summary of infantile hepatic hemangioma (IHH) and its misnomers and to dialectically present the differential diagnosis of these rare entities of the liver. Eligible peer-reviewed articles on hepatic infantile hemangiomas, published between 2000 and 2015, were reviewed for this study. IHH is the most common hepatic vascular tumor in children. Once a liver mass is identified in an infant, the differential diagnosis ranges from vascular malformations to benign and malignant tumors including mesenchymal hamartoma, hepatoblastoma, metastatic neuroblastoma, so careful physical examination, imaging studies, and, if indicated, tumor markers and biopsy, are of pivotal importance to ascertain the correct diagnosis. Despite the benign nature of IHHs, some of these lesions may demand medical and/or surgical intervention, especially for multiple and diffuse IHH. Complications can include hepatomegaly, hypothyroidism and cardiac failure. Therefore, a close follow-up is required until complete involution of the lesions. We propose an algorithm to guide the physicians towards the proper management of hepatic lesions. PMID:27610342

    With the progress of multidisciplinary vascular anomaly treatment, the use of radiotherapy, cryotherapy, laser therapy and medical treatments, the corticosteroid, sclerotherapy, and many more, the role of surgery has been refined. Surgical treatment has historically been the mainstay of treatment and will maintain.A miniature tourniquet technique applied to the tongue was successfully utilized in reducing bleeding to a minimum during surgical resection of a massive cavernous hemangioma involving the tongue and lower lip without any postoperative complications.Comprehensions of the neurovascular anatomy of the tongue, vasculature, innervations, and muscles physiological functions are very important for selecting the right surgical approach.A 9-year-old girl presented with giant hemangioma resulting in severe protrusions of the anterior and lateral two-thirds of the tongue with an extensive anterior open bite jaw deformity and oral physiological dysfunctions as speech, mastication, and deglutition. Such a presentation is a unique surgical challenge due to the high risk of bleeding, tongue swelling, and airway compromise.Postsurgical results showed oral physiological function improvement and the elimination of interaction effects on anterior open bite.

    Introduction: Pulsed dye laser (PDL) is an important treatment for superficial infantile hemangioma, but few studies report on its cellular mechanism. The aim of this study was to evaluate alterations of serum vascular endothelial growth factor (VEGF) level in infantile hemangioma (IH) patients after laser treatment and effects of PDL irradiation on human umbilical vein endothelial cells (HUVECs) in vitro, as well as to explore the biomolecular mechanisms and ultrastructure changes of the PDL effect. Methods: 74 children with infant hemangioma including 45 patients in proliferating phase, 18 patients in involuting phase, 11 patients in involuted phase and 10 healthy children were engaged in this study. The plasma VEGF levels of children were measured with the enzymelinked immunosorbent assay (ELISA). 24 hours after, HUVECs cultured in vitro were irradiated with PDL, cell apoptosis, mRNA levels of VEGF, and changes of ultrastructure were evaluated using flow cytometry, real-time reverse transcriptase polymerase chain reaction (RT-PCR), and transmission electron microscopy, respectively. Results: The serum VEGF concentrations in children with proliferating hemangiomas were significantly higher than in patients with involuting / involved hemangiomas and healthy patients. After receiving 3 laser treatments, the plasma VEGF levels of IH patients in proliferating hemangiomas decreased significantly. PDL irradiation could down-regulate VEGF mRNA expression of HUVECs, and increase cell apoptosis rate. Conclusion: The present study demonstrates that PDL irradiation imparts apoptosis induction effects on HUVECs in vitro. Furthermore, our results suggest that vascular endothelial growth factor may be of particular importance in pathophysiology and PDL treatment of hemangiomas, also serum VEGF levels may be used as an aid in the follow up of IH. This provides valuable evidence of the PDL effect on infantile hemangioma. PMID:25653803

    Hemangiomas of the small bowel are rare benign tumors, that are dangerous since they may cause massive or occult gastrointestinal bleeding. We describe a case of a jejunum cavernous hemangioma detected by computed tomography (CT) and barium studies. An abdominal CT scan (with intravenous contrast agent) depicted a pronounced contrast enhanced lesion arising from the front wall of a loop of the proximal ileum. Enteroclysis revealed a small intramural nodular defect. PMID:17933282

  2. Baseline thrombocytopenia complicated by recurrent episodes of transient severe thrombocytopenia following infections in an adult woman with a non involuting congenital hemangioma – a case report

    PubMed Central

    2013-01-01

    Background Congenital hemangiomas are benign abnormal proliferation of blood vessels. Noninvoluting congenital hemangiomas are a rare variant which persist, and may become bigger. Hemangiomas are known to be associated with thrombocytopenia, microangiopathic hemolytic anemia and Kasabach-Merritt phenomenon. Kasabach-Merritt phenomenon is characterized by consumptive coagulopathy with microangiopathic haemolyic anemia and thrombocytopenia. Platelet sequestration in the hemangioma or increased destruction which may either be immune or non immune are also further contributors to thrombocytopenia. Case presentation A 45 year old female with a non involuting hemangioma and baseline thrombocytopenia was observed to develop repeated episodes of transient severe thrombocytopenia associated with a variety of infectious conditions. Laboratory investigations suggested a peripheral mechanism. Platelet counts always returned to baseline levels on resolution of the precipitating infection. Conclusion The authors report this phenomenon as the first reported case of baseline thrombocytopenia complicated by recurrent episodes of transient severe thrombocytopenia following infections associated with a non involuting congenital hemangioma. The observations made in this patient were unique and hitherto unreported in medical literature. Both peripheral sequestration and destructive consumption were considered likely. Consumptive mechanisms were likely to encompass either or both immune and non immune causes. Further studies are needed to establish the precise pathogenesis. PMID:23758712

Goldmann perimetry examination showed inferior suppression of the right visual field center. Funduscopic examination revealed normal coloring of the right optic disc. Imaging studies showed an apical oval tumor. The optic nerve was compressed by both the tumor and the superior rectus muscle/levator palpebrae superioris complex. The tumor was dissected from the surrounding tissues and completely extracted. Histopathologic examination confirmed a cavernous hemangioma. The patient underwent three cycles of postoperative steroid pulse therapy. One year after the surgery, her visual acuity and CFF improved to 1.0 and 32 Hz OD, respectively. Her right visual field was within the normal range. PMID:27099610

    We report here the case of an infant with multiple hepatic and cutaneous infantile hemangiomas (IHs) associated with deranged liver function who was treated successfully with low-dose propranolol. We also discuss our recent data that show that IH is a developmental anomaly of hemogenic endothelium derived from primitive mesoderm with a neural crest-cell phenotype. We previously presented evidence that this hemogenic endothelium is governed by the renin-angiotensin system, which we propose can account for both the action of propranolol and the process of spontaneous involution of IH. We further speculate on the possibility of using inhibitors of angiotensin-converting enzyme and that of angiotensin II receptor 2 as potential alternative therapies. PMID:21357335

    Pyogenic granuloma (PG), more accurately known as lobular capillary hemangioma, is a benign vascular tumor that usually occurs in the skin or oral mucosa. This lesion is rarely reported in the gastrointestinal tract but is known to bleed if not resected. We herein describe a case series with the clinical, endoscopic, and histologic findings of four cases of gastrointestinal PG at our institution. In addition, we provide a review of the literature and summation of all reported cases of PG specific to the gastrointestinal tract. Based on our experience, we suggest that the actual incidence of gastrointestinal PG may in fact be higher than reported because PG can be unrecognized or improperly diagnosed. It is important for the clinician to properly recognize this lesion as a source of anemia and its propensity to bleed during biopsy or resection. PMID:27403353

    2012-02-01

    Purpose: An evaluation of dose-response relationship and an attempt to define predictive factors. Methods and Materials: A total of 137 cases of painful vertebral hemangioma irradiations (101 patients). Fraction dose (fd) varied from 2 to 15 Gy (123 fractionated and 14 radiosurgical treatments), and total dose (TD) from 8 to 30 Gy (111 cases irradiated with fd of 2 GY to TD of 24 Gy). We evaluated pain relief, changes in analgesic requirements, and reossification. Results: Means of pain relief 1, 6, 12, and 18 months after radiotherapy (defined as a decrease of primary pain level expressed in percent) were 60.5%, 65.4%, 68.3%, and 78.4%, respectively. Proportion of patients with no need for analgesics and patients using tramadol were 39%, 40%, 44%, 57%, and 20%, 17%, 22%, and 11% in these times. The proportion of patients experiencing complete/partial pain relief changed from 36/48% 1 month, to 64/22% 1.5 years after radiotherapy. No impact of radiotherapy on reossification was found. The positive impact of fd and TD increase for analgesics uptake reduction and pain relief was found. An increase of the fd by 1 Gy results in 27% chance of analgesics uptake reduction and 3.8% reduction of pain, whereas 14% analgesics uptake reduction and 2.2% of pain reduction in case of the TD. The predictive factors improving results were found: female gender, older age, better performance states (the chance of the lower analgesic treatment decreases over 2.5 times in comparison to the higher Zubrod degree), bigger Hb concentration, shorter symptoms duration and lower analgesics uptake before radiotherapy. Conclusions: The obtained data support the efficacy of radiotherapy in improving pain secondary to vertebral hemangioma, with the degree of pain amelioration being related to increasing fd and TD. The positive predictive factors were defined: female gender, older age, better performance status, increased Hb concentration, shorter symptoms duration, and lower analgesics uptake

    Introduction The acronym PHACES describes the association of posterior fossa malformations, facial hemangiomas, arterial anomalies (cardiovascular or cerebrovascular), coarctation of the aorta and cardiac defects, eye abnormalities, and sternal or ventral defects. In this study we report on 6 patients affected by the PHACES syndrome and showing 34 intraoral hemangiomas (IH), treated by diode laser photocoagulation (DLP). Case presentation IH appeared as red-bluish soft masses, smooth or lobulated, from a few millimetre to several centimetres in size, covered by intact mucosa and blanching on pressure. IHs were treated by DLP with 320 μm fibres at a wavelength of 800 ± 10 nm. The diode laser techniques applied were: Transmucosal DLP (DLTP), a no-contact technique in which laser energy is delivered by a flexible optic quartz fiber, which is kept 2–3 mm apart from the lesion, and Intralesional DLP (DLIP), in which the fibre is introduced into the lesion through a transmucosal access. DLTP was used for 20 flat, superficial IHs and, after a variable number of laser sessions (average = 3) depending on the size of the lesion, 65% completely regressed, while in the remaining 35% shrinkage of the lesion was achieved with minor and few complications. The remaining 14 deep/multi-lobulated IHs were treated by DLIP, resulting in complete regression of 79% of them. Conclusions DLP techniques are an effective and minimally invasive procedure for IH in patients with PHACES, in consideration of the multiple lesions to treat, of the necessity of multiple interventions and the higher compliance of the patients.

    Hemangiomas are benign dysplasias or vascular tumors consisting of vascular spaces lined with endothelium. Nowadays, radiotherapy for vertebral hemangiomas (VHs) is widely accepted as primary treatment for painful lesions. Nevertheless, the role of surgery is still unclear. The purpose of this study is to propose a novel algorithm of treatment about VHs. This is a case report of an extensive VH and a review of the literature. A case of vertebral fracture during radiotherapy at a total dose of 30 Gy given in 10 fractions (treatment time 2 weeks) using a linear accelerator at 15 MV high-energy photons for extensive VH is reported. Using PubMed database, a review of the literature is done. The authors have no study funding sources. The authors have no conflicting financial interests. In the literature, good results in terms of pain and neurological deficits are reported. No cases of vertebral fractures are described. However, there is no consensus regarding the treatment for VHs. Radiotherapy is widely utilized in VHs determining pain. Surgery for VHs determining neurological deficit is also widely accepted. Perhaps, regarding the width of the lesion, no indications are given. We consider it important to make an evaluation before initiating the treatment for the risk of pathologic vertebral fracture, since in radiotherapy, there is no convention regarding structural changes determined in VHs. We propose a new algorithm of treatment. We recommend radiotherapy only for small lesions in which vertebral stability is not concerned. Kyphoplasty can be proposed for asymptomatic patients in which VHs are small and in patients affected by VHs determining pain without spinal canal invasion in which the VH is small. In patients affected by pain without spinal canal invasion but in which the VH is wide or presented with spinal canal invasion and in patients affected by neurological deficits, we propose surgery.

    Background Epidemiological studies evaluating treatments for infantile hemangiomas have produced inconsistent results. A meta-analysis of published data was conducted to investigate the effectiveness and safety of oral propranolol versus other treatments for infantile hemangiomas. Methods A meta-analysis was conducted based on literature (published from 1960 to December 1, 2014) found on the PubMed, EMBASE, and OVID search engines. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were estimated for the outcome measures. Heterogeneity, publication bias and subgroup analysis were performed. Results A total of 61 studies involving 5,130 participants met the inclusion criteria. Propranolol was found to be a more effective modality in treating IHs (ORs = 0.92; 95%CI, 0.89–0.95) and had fewer complications compared to the other treatments including systemic steroids (ORs = 0.68; 95% CI, 0.59–0.76); laser ablation (ORs = 0.55; 95% CI, 0.43–0.67); other beta-adrenergic blockers (ORs = 0.56; 95% CI, 0.50–0.61) and surgery (ORs = 0.55; 95% CI, 0.28–0.81). A subgroup analysis of propranolol showed that a dose of 2 mg/kg/day or more yielded better outcomes (ORs = 0.92; 95% CI, 0.88–0.95; ORs = 0.95; 95% CI, 0.89–1.00), and IHs that had not been previously treated had better responses to propranolol treatment (ORs = 0.95; 95% CI, 0.91–0.98). Conclusions The meta-analysis demonstrated that propranolol was more effective and safer than other therapies in treating IHs. It provides strong evidence for supporting the use of propranolol as a first-line therapy for IHs. PMID:26375455

    Intraosseous hemangiomas in the jaws are rare lesions and may lead to several complications. The authors present a case of a 12-year-old girl with a radiolucent periapical lesion between tooth 35 and 36 where nocturnal exsanguinating bleeding started to occur from periodontal sulcus during orthodontic treatment. Diagnosis of an intraosseous hemangioma in the mandible was based on positive needle aspiration for blood, computed tomography and arteriography. At first the family chose to only follow-up the lesion but episodes of nocturnal hemorrhage were becoming more frequent and a treatment was requested. Embolization and dental extraction were performed in order to treat the lesion. After a follow-up period of 17 years no more cases of hemorrhage occurred and lesion regressed. PMID:25307825

    Renal hemangioma is a relatively rare benign tumor with a wide range of clinical and radiological presentation, not easy to differentiate preoperatively from a renal cancer. Due to its benign nature complete surgical resection is the recommended therapy and is considered curative. A 73-year old male patient followed-up for a lung carcinoma and a chronic renal failure underwent a CT scan showing a 35-mm mass of the inferior pole of the left kidney. The patient underwent robot-assisted partial nephrectomy with left inferior pole selective warm ischemia. The outcome was favorable and no repercussions on the renal reserve were observed postoperatively. Histopathological characteristics of the surgical specimen were consistent with renal cavernous hemangioma. A robot-assisted operation allows the fine dissection required to carry out a bloodless nephron-sparing surgery without a complete warm ischemia. The use of robot could be noteworthy for nephron-sparing surgery in cases of concomitant chronic renal failure. PMID:26712254

    Infantile hemangiomas (IHs) are the most common benign vascular neoplasms of infancy and childhood. The majority do not need medical intervention. However, large ulcerated scalp IHs may lead to fatal bleeding as well as severe cosmetic disfigurement that indicate early surgical excision, inflicting substantial surgical risks, with short- and long-term morbidity.The TopClosure Tension-Relief System (TRS) is an innovative skin stretching and wound closure-secure system that facilitates primary closure of relatively large skin defects. This system has been shown as a substitute for skin grafts, flaps, or tissue expanders.We describe a case of a giant IH of the scalp usually requiring a complex surgical approach, which was immediately primarily closed applying the TRS.A 3-day-old female infant presented with a giant scalp hemangioma at birth that rapidly grew in the neonatal period with early signs of ulceration. The patient underwent surgical resection of the giant scalp hemangioma with immediate primary closure of the defect using the TRS. Surgical procedure and postoperative period were uneventful.Early surgical resections of IHs at infancy carry substantial surgical risks and morbidity. This is the first reported case of early resection of a scalp hemangioma in the neonatal period, with successful immediate primary closure by application of stress-relaxation technique through the TRS. The application of the TopClosure TRS in this age group has significant advantages. It reduces the complexity and length of surgery, reducing blood loss, eliminating donor site morbidity, improving wound aesthetics, and minimizing the need for future reconstructive procedures.

    Labeled red blood cells (RBCs) have already been proven useful in the detection and localization of many vascular abnormalities. One such abnormality is that of a cavernous hemangioma. Cavernous hemangiomas have a distinct circulation and have been found in many areas of the body. The ability to utilize this unique circulation is important to consider when choosing a diagnostic exam. This paper reports a case demonstrating the usefulness of labeled red blood cells for the detection and localization of cavernous hemangioma of the bone. A 31-yr-old female present with a history of persistent generalized headaches for many years. About 1 yr prior to the exam, she noticed that her headaches had become more localized to the right side of her head. Physical examination revealed a palpable lump developing on the right side of her head which was sensitive to the touch. The patient was then scheduled for a CT scan to be followed by both a bone scan and a /sup 99m/Tc blood-pool scan. A flow study using 15 mCi /sup 99m/Tc labeled RBCs was performed in the right lateral position at 1.5 sec/frame for 32 frames. Immediate blood-pool images 30-min, and 1-hr delayed images were recorded.

    Anastomosing hemangioma, a recently recognized benign vascular neoplasm originally described in the kidney, may be confused with well-differentiated angiosarcoma. Rare cases of anastomosing hemangiomas have been described in the liver and in nonrenal genitourinary sites. We report a series of 17 anastomosing hemangiomas occurring in unusual locations, in particular in the paravertebral soft tissues. The 17 tumors occurred in 10 male and 6 female patients, ranging in age from 2 to 85 years. One patient had bilateral, synchronous tumors involving the right paracaval and left para-aortic soft tissues. Thirteen (76%) cases involved the soft tissues near the vertebral column, including the paravertebral region (n=4), the psoas muscle (n=2), the costovertebral angle (n=2), para-aortic soft tissue (n=2), and the paracaval, parasacral, and retroperitoneal soft tissues (n=1 each). Other locations included the anterior mediastinum, uterine cornu, infundibular pelvic ligament, and upper arm (n=1 each). Imaging studies, available in 13 cases, were not felt to be diagnostic of a hemangioma. The tumors ranged from 1.5 to 7.5 cm (median, 3.6 cm) in size and were grossly well demarcated. All cases showed typical morphologic features of anastomosing hemangiomas, including a nonlobular architecture, an anastomosing proliferation of capillary-sized vessels with mild endothelial cell nuclear variability, scattered hobnailed endothelial cells, and small fibrin thrombi. Mitotic activity was rare or absent. Adipocytic metaplasia and extramedullary hematopoiesis were present in subsets of cases. When performed, immunohistochemical studies showed expression of endothelial markers (eg, CD31, CD34). In only 1 case did the submitting pathologist favor a diagnosis of anastomosing hemangioma; 4 cases were submitted specifically to exclude a well-differentiated angiosarcoma. Clinical follow-up available in 13 cases has not revealed any local recurrences or metastases. This series, the first

    Hemangiomas of the uterine cervix are rare with only about 55 cases reported in the literature. Increased awareness of this unusual cervical lesion can lead to early diagnosis and conservative therapeutic approaches. We present a series of four patients with cervical hemangioma with an extensive review of the existing literature on the subject. All four cervical hemangiomas were diagnosed incidentally in hysterectomy specimens performed for persistent menorrhagia or pain. The mean age at presentation was 34 years. The mean lesion size was 2.1cm and the dominant location was posterior cervix (3 cases). Immunohistochemistry for estrogen and progesterone receptors showed expression of both markers in endothelial cells and stroma, the latter marker showing a stronger and more diffuse pattern. No other significant uterine abnormality was identified in two cases. The vast majority of cervical hemangiomas reported are in reproductive age women. In addition, these lesions express hormone receptors, indicating that their growth is at least in part due to sex hormone stimulation. Although most lesions are symptomatic (mostly bleeding), the diagnosis is frequently unsuspected. Cervical hemangiomas are benign with no recurrences or adverse outcomes reported to date. Conservative treatments are usually successful, and spontaneous remission has been observed. This entity should be included in the differential diagnosis of patients with abnormal vaginal bleeding, particularly in patients of reproductive age with no other clinical and radiologic findings that would explain the symptoms.

In this study, we investigated the anti-angiogenic potential of SEMA3E and SEMA3F (SEMA3E&F) in infantile hemangioma (IH). IH is a common vascular tumor that involves both vasculogenesis and angiogenesis. Our lab has identified and isolated hemangioma stem cells (HemSC), glucose transporter 1 positive (GLUT1{sup +}) endothelial cells (designated as GLUT1{sup sel} cells) based on anti-GLUT1 magnetic beads selection and GLUT1-negative endothelial cells (named HemEC). We have shown that these types of cells play important roles in hemangiogenesis. We report here that SEMA3E inhibited HemEC migration and proliferation while SEMA3F was able to suppress the migration and proliferation in all three types of cells. Confocal microscopy showed that stress fibers in HemEC were reduced by SEMA3E&F and that stress fibers in HemSC were decreased by SEMA3F, which led to cytoskeletal collapse and loss of cell motility in both cell types. Additionally, SEMA3E&F were able to inhibit vascular endothelial growth factor (VEGF)-induced sprouts in all three types of cells. Further, SEMA3E&F reduced the level of p-VEGFR2 and its downstream p-ERK in HemEC. These results demonstrate that SEMA3E&F inhibit IH cell proliferation and suppress the angiogenic activities of migration and sprout formation. SEMA3E&F may have therapeutic potential to treat or prevent growth of highly proliferative IH. - Highlights: • SEMA3E&F reduce actin stress fibers and induce cytoskeletal collapse in HemEC. • SEMA3E&F inhibit angiogenic activities of HemEC. • SEMA3E&F can interrupt the VEGF-A-VEGFR2-ERK signaling pathway in HemEC. • Plexin D1 and NRP2 are induced during HemSC/GLUT1{sup sel}-to-EC differentiation.

    We report herein the case of a 28-year-old woman with a rectal cavernous hemangioma in whom recurrent rectal bleeding and marked anemia were interpreted as being caused by her coexisting internal hemorrhoids, resulting in a delay in the correct diagnosis for 1 year. Digital examination revealed a walnut-sized, wide-based, and elastic soft mass, 3 cm proximal from the anal verge, in addition to the internal hemorrhoids. Colonofiberscopy revealed a bluish submucosal lesion with superficial capillary dilatation at the same site. A transanal local resection was performed and the histological diagnosis of the tumor was cavernous hemangioma. The patient has been well without any recurrence of rectal bleeding for 2 years and 6 months since her operation. Thus, although rectal cavernous hemangioma is rare, a lack of awareness of this condition could lead to misdiagnosis as hemorrhoids and subsequent inappropriate therapy. PMID:7865962

    Ovarian hemangiomas are usually of the cavernous type, and are rarely encountered. A 73-year-old woman presented with lower abdominal discomfort. Subsequent physical examination depicted a palpable mass in the lower abdomen. Abdominopelvic computed tomography (CT) revealed a well-circumscribed mass with thin septa measuring 12.1 × 9.0 cm in the right ovary. Levels of the tumor markers cancer antigen (CA)-125 and CA 19-9 were within the normal range. At laparoscopy, the tumor was found to be confined to the right ovary and to have a smooth surface. The final histopathological result was ovarian cavernous hemangioma. Microscopically, the mass consisted of multiple, dilated, blood-filled vascular channels separated by loose connective tissue, and all were lined by a single layer of flattened endothelium. The authors present a case of ovarian cavernous hemangioma presenting as a large growing mass in a postmenopausal woman and review previously published literature. PMID:26793681

    Purpose: To investigate the potential utility of in-line phase-contrast imaging (ILPCI) technique with synchrotron radiation in detecting early hepatocellular carcinoma and cavernous hemangioma of live using in vitro model system. Methods: Without contrast agents, three typical early hepatocellular carcinoma specimens and three typical cavernous hemangioma of live specimens were imaged using ILPCI. To quantitatively discriminate early hepatocellular carcinoma tissues and cavernous hemangioma tissues, the projection images texture feature based on gray level co-occurrence matrix (GLCM) were extracted. The texture parameters of energy, inertia, entropy, correlation, sum average, sum entropy, difference average, difference entropy and inverse difference moment, were obtained respectively. Results: In the ILPCI planar images of early hepatocellular carcinoma specimens, vessel trees were clearly visualized on the micrometer scale. Obvious distortion deformation was presented, and the vessel mostly appeared as a ‘dry stick’. Liver textures appeared not regularly. In the ILPCI planar images of cavernous hemangioma of live specimens, typical vessels had not been found compared with the early hepatocellular carcinoma planar images. The planar images of cavernous hemangioma of live specimens clearly displayed the dilated hepatic sinusoids with the diameter of less than 100 microns, but all of them were overlapped with each other. The texture parameters of energy, inertia, entropy, correlation, sum average, sum entropy, and difference average, showed a statistically significant between the two types specimens image (P<0.01), except the texture parameters of difference entropy and inverse difference moment(P>0.01). Conclusion: The results indicate that there are obvious changes in morphological levels including vessel structures and liver textures. The study proves that this imaging technique has a potential value in evaluating early hepatocellular carcinoma and cavernous

    Background Cavernous hemangiomas are the most frequent neoplasms of the liver and in routine clinical practice they often need to be differentiated from malignant tumors and other benign focal lesions. The purpose of this study is to evaluate whether diagnostic accuracy of magnetic resonance imaging (MRI) of hepatic hemangiomas, showing atypical pattern on US, improves with the use of Gd-BOPTA in comparison with contrast-enhanced multi-phase computed tomography (CT). Methods 178 consecutive patients with ambiguous hepatic masses showing atypical hyperechoic pattern on grey-scale US, underwent unenhanced and contrast-enhanced multi-phase multi-detector CT and MR (1.5T) with the use of liver-specific contrast medium gadobenate dimeglumine (Gd-BOPTA). After intravenous contrast administration arterial (HAP), venous-portal (PVP), equilibrium phases (EP) both in CT and MR and additionally hepatobiliary phase (HBP) in MR were obtained. 398 lesions have been detected including 99 hemangiomas and 299 other lesions. Results In non-enhanced MDCT examination detection of hemangiomas was characterized by sensitivity of 76%, specificity of 90%, PPV of 71%, NPV of 92% and accuracy of 86%. Non-enhanced MR examination showed sensitivity of 98%, specificity of 99%, PPV of 99%, NPV of 99% and accuracy of 99%. After intravenous administration of contrast medium in MR the mentioned above parameters did not increase significantly. Conclusion Gd-BOPTA-enhanced MR in comparison with unenhanced MRI does not improve diagnostic accuracy in discriminating hemangiomas that show non-specific appearance in ultrasound examination. Unenhanced MR as a method of choice should directly follow US in course of diagnostic algorithm in differentiation of hemangiomas from other liver tumors. PMID:21504593

  6. Co-development of pyogenic granuloma and capillary hemangioma on the alveolar ridge associated with a dental implant: a case report

    2014-01-01

    Introduction The development of various benign oral mucosal lesions associated with dental implants, such as pyogenic granuloma or peripheral giant cell granuloma, has been rarely reported. However, the occurrence of vascular diseases, such as hemangioma, related to dental implants has not been explored in the literature. In this study, we report a case of co-development of pyogenic granuloma and capillary hemangioma on the alveolar ridge associated with a dental implant in a patient undergoing antithrombotic therapy. To the best of our knowledge, this is first case of hemangioma formation associated with a dental implant. Case presentation A 68-year-old Korean man was referred for intermittent bleeding and a dome-shaped overgrowing mass on his upper alveolar ridge. He underwent dental implantation 5 years ago, and was started on warfarin for cerebral infarction a year ago. He had experienced gum bleeding and gingival mass formation 6 months after warfarinization; then, his implant fixture was removed. However, his gingival mass has been gradually increasing. The gingival mass was surgically excised, and revealed the coexistence of pyogenic granuloma and capillary hemangioma in histological analysis of the specimen. The lesion has showed no recurrence for more than a year. Conclusions Regarding immunostaining features, the endothelial cell markers, CD34 and CD31, and the mesenchymal cell marker, vimentin, were strongly detected, but cell proliferation marker, Ki-67, was negatively expressed in the endothelial cells of the hemangioma portion. However, in the pyogenic granuloma portion, CD34 was almost negatively detected, whereas vimentin and Ki-67 were highly detected in the fibroblast-like tumor cells. According to these heterogeneous characteristics of the lesion, the patient was diagnosed with coexistence of pyogenic granuloma and capillary hemangioma associated with the dental implant on the attached gingiva. We recommend that patients with dental implants who

    Sclerosing cholangitis (SC) is a rarely reported morbidity secondary to transcatheter arterial chemoembolization (TACE) with bleomycin-iodinated oil (BIO) for liver cavernous hemangioma (LCH). This report retrospectively evaluated the diagnostic and therapeutic course of a patient with LDH who presented obstructive jaundice 6 years after TACE with BIO. Preoperative imaging identified a suspected malignant biliary stricture located at the convergence of the left and right hepatic ducts. Operative exploration demonstrated a full-thickness sclerosis of the hilar bile duct with right hepatic duct stricture and right lobe atrophy. Radical hepatic hilar resection with right-side hemihepatectomy and Roux-en-Y hepaticojejunostomy was performed because hilar cancer could not be excluded on frozen biopsy. Pathological results showed chronic pyogenic inflammation of the common and right hepatic ducts with SC in the portal area. Secondary SC is a long-term complication that may occur in LCH patients after TACE with BIO and must be differentiated from hilar malignancy. Hepatic duct plasty is a definitive but technically challenging treatment modality for secondary SC. PMID:25516686

    Hemangioma (HA) can be exposed to bisphenol A (BPA) through direct skin absorption. Although numerous studies indicated that BPA can trigger the progression of cancers, there is no study concerning the effects of BPA on development of HA. Our present study revealed that nanomolar BPA can significantly increase the in vitro migration and invasion of HA cells via induction of epithelial-mesenchymal transition (EMT), which was evidenced by the upregulation of vimentin and downregulation of E-cadherin. The BPA treatment also significantly increased the expression and nuclear localization of Snail and the key transcription factor of EMT, while it had no effect on the expression of other transcription factors such as Slug, Twist, or ZEB1. Silencing of Snail by small interfering RNAs attenuated BPA-induced downregulation of cadherin and upregulation of vimentin, suggesting that Snail is essential for BPA-induced EMT. Both estrogen receptor α (ERα) and G protein-coupled estrogen receptor (GPER) were expressed in HA cells; furthermore, BPA treatment can increase the expression of both ERα and GPER. However, only the inhibitor of ERα (ICI 182, 780), and not GPER (G15), can abolish BPA-induced upregulation of Snail. It suggested that ERα is involved in BPA-induced EMT of HA cells. Collectively, our data suggested that BPA can trigger the EMT of HA cells via ERα/Snail signals. It indicated that more attention should be paid to the skin exposure to BPA for HA patients.

    Epithelioid hemangioma (EH) is a benign neoplasm with distinctive vasoformative features, which occasionally shows increased cellularity, cytologic atypia, and/or loco-regional aggressive growth, resulting in challenging differential diagnosis from malignant vascular neoplasms. Based on two intra-osseous EH index cases with worrisome histologic features, such as the presence of necrosis, RNA sequencing was applied for possible fusion gene discovery and potential subclassification of a novel atypical EH subset. A ZFP36-FOSB fusion was detected in one case, while a WWTR1-FOSB chimeric transcript in the other, both were further validated by FISH and RT-PCR. These abnormalities were then screened by FISH in 44 EH from different locations with 7 additional EH revealing FOSB gene rearrangements, all except one being fused to ZFP36. Interestingly, 4/6 penile EH studied showed FOSB abnormalities. Although certain atypical histologic features were observed in the FOSB-rearranged EH, including solid growth, increased cellularity, mild to moderate nuclear pleomorphism, and necrosis in 3/9 cases, no overt sarcomatous areas were discerned to objectively separate the lesions from the fusion-negative EH. No patient has developed recurrence to date, but the follow-up was relatively limited and short to draw definitive conclusions regarding behavior. Although FOSB-rearranged EH do not show significant morphologic overlap with SERPINE1-FOSB fusion-positive pseudomyogenic hemangioendothelioma, FOSB oncogenic activation is emerging as an important event in these benign and intermediate groups of vascular tumors.

    Infantile hemangiomas (IH) complicated by ulceration, disfigurement, functional impairment or life-threatening conditions need early, safe and effective treatment. This study explores the impact of propranolol on complicated IH. We report our experience of 62 patients treated with oral propranolol for complicated IH. The effect of propranolol was assessed using a score on a visual analogue scale integrated with echo, magnetic resonance or endoscopic findings. The average age at the beginning of the treatment was seven months [standard deviation (SD)±8.9], with a median of four months (range 1-53 months). The average age at the end of the treatment was 15 months (SD±8.4), with a median of 13 months (range 7-59 months). The mean treatment length was eight months (SD±3.2). Oral propranolol was successful in 95.2% of the patients in reducing the volume, the intensity of color and the elevation of IH. Statistically significant improvement of IH volume was observed in the first two months of therapy (P≤0.001), and between the second month and the end of the treatment (P<0.05). No significant bradycardia or hypotension occurred. Severe hypoglycemia occurred in one patient. Mild adverse effects were observed in seven patients. Our study demonstrates that propranolol administered orally at 2 to 3 mg/kg/day has a rapid therapeutic effect leading to remarkable shortening of the natural course of IH and it is safe in the majority of patients.

    Background Lobular capillary hemangioma (LCH) is an acquired benign vascular tumor of unknown origin. It usually affects skin and mucous membranes of the oropharynx. It rarely involves the nasal cavity which most commonly manifests as epistaxis. To our knowledge, only fifteen pediatric intranasal LCH cases have been reported in the literature. None of these occurred in the inferior turbinate. We report two new pediatric cases of LCH, one of them on the inferior turbinate and the other one on the anterior nasal septum. Our principal aim was to highlight the importance of considering this lesion as a differential diagnosis for pediatric unilateral nasal obstruction and epistaxis. Methods Retrospective case series and review of current literature regarding the possible causes, diagnosis, and treatment of nasal LCH. Description of cases Two adolescents presented with symptoms of unilateral nasal obstruction and epistaxis. Plain and contrast enhanced computed tomography revealed a well-defined intensely enhancing lesion in both cases. Patients underwent transnasal endoscopic excision and bipolar electrocautery at the base of the tumor for hemostasis. Histopathological examination confirmed the diagnosis of LCH. Discussion Current epidemiological and pathophysiological data suggests that the development of LCH may be associated to previous nasal trauma or endocrine disorders. LCH should be considered in the differential diagnosis of all pediatric endonasal masses associated with unilateral epistaxis and nasal obstruction. Endoscopic total excision with bipolar electrocautery for hemostasis is an appropriate treatment. PMID:27144115

    Renal anastomosing hemangiomas (RAH) has been recently proposed as a new entity. In this article, we summarize the clinicopathologic features of this tumor. RAH usually develops on a background of end-stage renal disease. Macroscopically, tumors are well-defined and their cut surface shows mahogany brown spongy tissue with epicenter in the renal medulla. Tumors are usually small, but larger lesions are reported. On microscopic examination, the tumor consists of sinusoid-like vascular channels lined by cuboidal endothelial cells with occasional hobnail-like appearance of endothelial cells closely mimicking splenic sinusoids. Eosinophilic hyaline globules may be present in the cytoplasm of neoplastic endothelial cells. Extramedullary hematopoiesis containing erythroid precursor and megakaryocytes may be present in the vascular lumens. Immunohistochemically, endothelial cells are positive for CD31 and CD34, but negative for D2-40, GLUT-1 and HHV8. The surrounding stroma around endothelial cells demonstrates positivity for  smooth muscle action. To date, there are no studies on molecular genetic aspects of RAH. This tumor is indolent based on site and size of the lesion, partial or nephrectomy is sufficient as a therapeutic modality. PMID:27543862

    The purpose of this retrospective study was to evaluate feline primary conjunctival vascular tumors of endothelial origin. Eight cases (six hemangiomas, two hemangiosarcomas) from a collection of 3460 feline submissions between 1993 and 2004 were evaluated using routine hematoxylin and eosin (H&E). Signalment, location, size, duration, epithelial pigmentation, margins, adjuvant therapy, outdoor activity, and geographic location, comparing ultraviolet (UV) radiation levels by state, were recorded. Follow-up information was available for five cases. In this study, the average age was 10.6 years, with neutered males over-represented. The Domestic Short-haired cat was most commonly affected. The most common anatomic site was the nictitating membrane, with the left eye preferentially affected. The average size and duration, prior to presentation, was 7.5 mm and 4.4 months, respectively. Seven of eight cases were devoid of epithelial pigmentation in nonaffected areas and the majority of cases were from states with high annual UV-light exposure. Only cases of hemangiosarcoma underwent surgical re-excisions following incomplete excision; however, no further recurrences were reported. No cases evaluated had evidence of metastatic disease at the time of excision. Surgical excision alone may be curative. However, recurrence is possible. These tumors demonstrate similar predilection sites and involvement of nonpigmented epithelium, as is true in canine cases, which may relate to risk factors as well. PMID:16771757

    Infantile hemangioma (IH) is one of the most common benign vascular tumors in children. A variety of treatment methods have been documented for the management of IH over the past years, including pharmacotherapy via oral administration or injection of corticosteroids, vincristine, alpha interferon and bleomycin; laser therapy, radionuclide therapy, cryotherapy and excisional surgery. The therapeutic efficacy of each treatment modality is variable, while adverse effects or complications are common and sometimes serious. Since the serendipitous discovery of propranolol, a nonselective beta-adrenergic receptor blocker, being very efficacious in treating IH in 2008, oral propranolol has earned a role as a first-line medical therapy for complicated IH. However, the appropriate drug dosage, dosing regimen, time for initiation, optimal duration, monitoring for side effects remains controversial. To standardize the use of propranolol in treating IH, avoid overtreatment or under-treatment, as well as minimize complications, a Chinese experts consensus on the use of oral propranolol for treatment of IH has been approved and written by a multidisciplinary experts group based on an up-to-date literature review and repeated discussion.

    Purpose: The current study analyzes the potential role of radiotherapy (RT) in symptomatic vertebral hemangioma (SVH). Methods and Materials: Seven cooperating German institutions collected clinical information, treatment plans, and outcome data for all patients with SVH referred for local RT. Results: From 1969 to 2008, a total of 84 patients with 96 symptomatic lesions were irradiated for SVH. The primary indication for radiotherapy was pain (97.6%), and 28.6% of patients had additional neurological symptoms. RT was performed at a median total dose of 34 Gy, with a median single dose of 2.0 Gy. After receiving a median follow-up of 68 months, the overall patient response rate was 90.5%. Complete symptom remission occurred in 61.9% of patients, 28.6% of patients had partial pain relief, and 9.5% of patients had no pain relief. In 26.2% of patients, radiological signs of reossification were observed in long-term follow-up but not significantly correlated with pain relief. Most importantly, total doses of >=34 Gy resulted in significantly greater symptomatic relief and control rate than total doses of <34 Gy. Conclusions: This study consists of the largest database of cases reported so far using RT for SVH. RT is easy, safe, and effective for pain relief treatment for SVH. Total doses of at least 34 Gy give the best symptomatic response.

    Infantile hemangiomas (IH) are common vascular growths that occur in 5-10% of neonates and have the potential to cause disfiguring and even life-threatening complications. Currently, no objective tool exist to monitor either progression or treatment of IH. To address this unmet clinical need, we have developed a handheld wireless device (HWD) that uses diffuse optical spectroscopy for the assessment of IH. The system employs 4 wavelengths (l=780nm, 805nm, 850nm, and 905nm) and 6 source-detector pairs with distances between 0.6 and 20 mm. Placed on the skin surface, backreflection data is obtained and a multispectral evolution algorithm is used to determine total hemoglobin concentration and tissue oxygen saturation. First results of an ongoing pilot study involving 13 patients (average enrollment age = 25 months) suggest that an increase in hypoxic stress over time can lead to the proliferation of IH. Involuting IH lesions showed an increase in tissue oxygen saturation as well as a decrease in total hemoglobin.

    Over the past 27 years cavernous hemangioma of the liver has been diagnosed in 12 nonoperated patients and in 16 patients who had resection of the lesion at Strong Memorial Hospital. In almost all patients the diagnosis was suggested by an imaging procedure. In the 12 nonoperated patients the average size of the tumor was 4.7 cm (range: 3-8 cm). No problems related to the tumor occurred during the follow-up period. The average size of the resected lesion was 10 cm (range: 4-32 cm). The usual indication for resection was pain, mass, or a combination of these manifestations. Five lobectomies, five left lateral segmentectomies, two trisegmentectomies, two segmentectomies, and two enucleations were performed. There were no postoperative deaths. Review of the literature indicates that although rapid growth of the lesion occurred during pregnancy in one patient, the effects of pregnancy or contraceptive drugs on growth are inconsistent. Spontaneous rupture occurs infrequently, and the potential for rupture should not constitute an indication for resection, which should be performed selectively. Intraoperative blood loss may be appreciable, but a mortality rate near 0% has been reported in all institutional series. Images Figs. 2A-D. Figs. 3A-C. Figs. 3A-C. Figs. 4A and B. PMID:3555360

    The aim of the present study was to assess the efficacy and safety of topical timolol maleate combined with oral propranolol for parotid infantile hemangiomas. Between October 2012 and April 2014, propranolol was administered orally at a dose of 1.0–1.5 mg/kg/day to 22 infants with proliferating hemangiomas in the Department of Oral and Maxillofacial Surgery (Hospital of Stomatology, China Medical University, Shenyang, Liaoning, China). A small amount of 0.5% timolol maleate eye drop solution was topically applied with medical cotton swabs to the area of the lesion twice a day, every 12 h. The study group consisted of 9 males and 13 females, aged 2–9 months, with a median age of 4.7 months. The lesions were all located in the parotid region, and measured between 3.5×4×0.5 and 7×8×3 cm in volume. The planned duration of therapy was 6–8 months, or the two drugs were stopped when complete regression of the lesions was obtained. The therapeutic outcomes and safety were assessed by the change in the size and color of the tumor, and the presence of adverse effects throughout the course of treatment. The mean duration of therapy was 21.1 weeks and ranged from 3 to 8 months. Of the 22 patients, 16 demonstrated an excellent response, 6 showed a good response and 2 displayed a moderate response. No major collateral effects were observed. Overall, oral propranolol combined with topical timolol maleate may be used as the first-line therapeutic choice in the treatment of infantile parotid mixed hemangioma. PMID:27588127

    Introduction: Pure spinal epidural cavernous hemangiomas (PSECHs) are rare vascular lesions with about 100 cases reported. Herein, we present a case series of 7 PSECHs discussing their clinical presentation, radiological characteristics, surgical technique and intraoperative findings, pathological features, and functional outcome. Materials and Methods: We retrieved from the retrolective databases of the senior authors, patients with pathologically confirmed PSECH operated between January 2002 and November 2015. From their medical records, the patients’ sociodemographic, clinical, radiological, surgical, and histopathological data were retrieved and analyzed. Results: The mean age of the seven cases was 50.3 years. Four were females. All the five cases (71.4%) in the thoracic spine had myelopathy and the 2 (28.6%) lumbar cases had sciatica. Local pain was present in all the cases. All the lesions were isointense on T1-weighted images, hyperintense on T2-weighted images, and in five cases there was strong homogeneous enhancement. In six cases (85.7%), classical laminectomy was done; lesions resected in one piece in five cases. Total excision was achieved in all the cases. Lesions were thin-walled dilated blood vessels, lined with endothelium, and engorged with blood and with scanty loose fibrous stroma. The median follow-up was 12 months (range: 1–144 months). All patients gradually improved neurologically and achieved a good outcome with no recurrence at the last follow-up. Conclusion: PSECH although rare is increasing reported and ought to be included in the differential diagnosis of spinal epidural lesions. Early surgical treatment with total resection is recommended as would result in a good prognosis.

    AIM: To analyze the evolution in the management of airway infantile hemangioma (AIH) and to report the results from 3 pediatric tertiary care institutions. METHODS: A retrospective study of patients with diagnosis of AIH and treated in 3 pediatric tertiary care institutions from 1996 to 2014 was performed. RESULTS: Twenty-three patients with diagnosis of AIH were identified. Mean age at diagnosis was 6 mo (range, 1-27). Single therapy was indicated in 16 patients and 7 patients received combined therapy. Two therapeutic groups were identified: Group A included 14 patients who were treated with steroids, interferon, laser therapy and/or surgery; group B included 9 patients treated with oral propranolol. In group A, oral corticosteroids were used in 9 patients with a good response in 3 cases (no requiring other therapeutic option), the other patients required additional treatment options. Cushing syndrome was observed in 3 patients. One patient died of a fulminant sepsis. Open surgical excision and endoscopic therapy were performed in 11 patients (in 5 of them as a single treatment) with a response rate of 54.5%. Stridor persisted in 2 cases, and one patient died during the clinical course of bronchial aspiration. In group B, oral propranolol was used in 9 patients (in 8 of them as a single treatment) with a response rate of 100%, with an mean treatment duration of 7 mo (range, 5-10); complications were not observed. CONCLUSION: Our experience and the medical literature support the use of propranolol as a first line of treatment in AIH. PMID:26862508

    Splenic hamartoma is a rare tumor-like lesion composed of structurally disorganized red pulp elements. It has been hypothesized that two other splenic lesions, cord capillary hemangioma and myoid angioendothelioma, may fall within the spectrum of splenic hamartoma, simply representing morphological variants. In this study, we compared the vascular and stromal composition of cord capillary hemangioma and myoid angioendothelioma with those of classical hamartoma. In addition, we assessed the clonal vs polyclonal nature of the lesions in nine female cases by performing clonality analysis for X-chromosome inactivation at the human androgen receptor locus (HUMARA) on laser-assisted microdissected samples. In 15 of 17 cases, increased reticulin and/or collagen content was observed. The classical hamartoma cases showed a vasculature predominantly composed of CD8+ CD31+ CD34- splenic sinuses, whereas cases of cord capillary hemangioma and myoid angioendothelioma contained many CD8- CD31+ CD34+ cord capillaries, but very little CD8+ vasculature. All cases lacked expression of D2-40 and Epstein Barr virus-encoded RNA. All cases showed a proliferation index of ≤5% by Ki-67. Cases of classical hamartoma lacked significant perisinusoidal expression of collagen IV and low-affinity nerve growth factor receptor. Both markers were variably expressed in the other lesions. Increased CD163-positive histiocytes were found in four cases (three cord capillary hemangiomas and one myoid angioendothelioma). HUMARA analysis was informative in all nine tested cases, of which three cases showed a non-random X-chromosome inactivation pattern, indicating clonality. All three clonal cases were cord capillary hemangiomas. Our study has shown that in spite of considerable morphologic heterogeneity and overlapping features, classical hamartoma and cord capillary hemangioma and myoid angioendothelioma are different in terms of their vascular and stromal composition. Clonality analysis supports a

    The clinical efficacy and safety profile of propranolol 1% cream in treatment of superficial infantile hemangiomas (IHs) were determined in a preliminary randomized group of eight infants. Five boys and three girls, 3 to 12 months old, with an IHs superficial capillary type on the forehead, posterior side of the neck, forearm, abdomen, or posterior side of the trunk were examined at our outpatient clinic between 2011 and 2014. Topical propranolol was applied twice daily for 10 months with clinical evaluation and photographic documentation performed every 1 to 2 months. Size, texture, and color changes were monitored. Therapeutic efficacy was evaluated using the Archauer system: Grade I (bad) reduction in size < 25%, Grade II (medium) reduction between 26% and 50%, Grade III (good) reduction between 51% and 75%, and Grade IV (excellent) reduction > 75%. The majority of hemangiomas treated, 62.5%, achieved Grade IV. A Grade III outcome was noticed in one patient with an IH (12.5%) and Grade II in 25% of patients with IHs on the abdomen. The treatment was well tolerated without side effects, which indicates that topical application of 1% propranolol is a safe, effective, and cheap therapeutic option for treating superficial IHs.

    Purpose We aimed to evaluate the histologic and radiologic findings of vascular lesions after stereotactic radiosurgery (SRS) categorized as radiation-induced cavernous hemangioma (RICH). Materials and Methods Among 89 patients who underwent neurosurgery for cavernous hemangioma, eight RICHs from 7 patients and 10 de novo CHs from 10 patients were selected for histopathological and radiological comparison. Results Histologically, RICHs showed hematoma-like gross appearance. Microscopically, RICH exhibited a hematoma-like area accompanied by proliferation of thin-walled vasculature with fibrin deposits and infiltrating foamy macrophages. In contrast, CHs demonstrated localized malformed vasculature containing fresh and old clotted blood on gross examination. Typically, CHs consisted of thick, ectatic hyalinized vessels lined by endothelium under a light microscope. Magnetic resonance imaging of RICHs revealed some overlapping but distinct features with CHs, including enhancing cystic and solid components with absence or incomplete popcorn-like appearance and partial hemosiderin rims. Conclusion Together with histologic and radiologic findings, RICH may result from blood-filled space after tissue destruction by SRS, accompanied with radiation-induced reactive changes rather than vascular malformation. Thus, the term "RICH" would be inappropriate, because it is more likely to be an inactive organizing hematoma rather than proliferation of malformed vasculature. PMID:26446658

    This study aims to compare contrast enhanced ultrasound (CEUS) and contrast enhanced magnetic resonance imaging (CEMRI) for the detection and characterization of hepatic hemangiomas. Included in this retrospective study were 83 histopathologically confirmed lesions of hemangioma in 66 hospitalized patients who underwent both CEUS and CEMRI and received surgery. The enhancement patterns on CEUS and CEMRI in each lesion were compared and analyzed. In addition, data obtained by the two modalities were then compared with the pathological findings to determine their value in differential diagnosis of hepatic hemangiomas. CEUS diagnosed 78 lesions of hemangioma against 80 by CEMRI. There were no statistical significant differences in the diagnostic value between CEUS and CEMRI in terms of sensitivity (88.0% vs. 92.8%), specificity (99.0% vs. 99.4%), accuracy (97.3% vs. 98.4%), positive predictive value (93.6% vs. 96.3%), and negative predictive value (98.0% vs. 98.8%) (p > 0.05, all). In the arterial phase, the main enhancement pattern on both CEUS and CEMRI was peripheral nodular enhancement (73 vs. 76), but lesions with diffuse enhancement on CEUS outnumbered those on CEMRI (3 vs. 1) and lesions with circular enhancement on CEMRI outnumbered those on CEUS (3 vs. 2). In the portal venous phase and delayed phase, the main enhancement pattern was hyperechoic change on CEUS and hyperintense on CEMRI (66 vs. 65), some lesions presented isoechoic change (12 vs. 15). These results suggested CEUS, an equivalent to CEMRI, may have an added diagnostic value in hemangiomas. PMID:25971695

    Avian leukosis virus subgroup J (ALV-J) infection can cause tumors and immunosuppression. Since the precise mechanism of the innate immune response induced by ALV-J is unknown, we investigated the antiviral innate immune responses induced by ALV-J in chicks and chickens that had developed tumors. Spleen levels of interleukin-6 (IL-6), IL-10, IL-1β, and interferon-β (IFN-β) were not significantly different between the infected chick groups and the control groups from 1 day post hatch to 7 days post hatch. However, IL-6, IL-1β, and IFN-β protein levels in the three clinical samples with hemangiomas were dramatically increased compared to the healthy samples. In addition, the anti-inflammatory cytokine IL-10 increased sharply in two of three clinical samples. We also found a more than 20-fold up-regulation of ISG12-1 mRNA at 1 day post infection (d.p.i.) and a twofold up-regulation of ZC3HAV1 mRNA at 4 d.p.i. However, there were no statistical differences in ISG12-1 and ZC3HAV1 mRNA expression levels in the tumorigenesis phase. ALV-J infection induced a significant increase of Toll-like receptor 7 (TLR-7) at 1 d.p.i. and dramatically increased the mRNA levels of melanoma differentiation-associated gene 5 (MDA5) in the tumorigenesis phase. Moreover, the protein levels of interferon regulatory factor 1 (IRF-1) and signal transducer and activator of transcription 1 (STAT1) were decreased in chickens with tumors. These results suggest that ALV-J was primarily recognized by chicken TLR7 and MDA5 at early and late in vivo infection stages, respectively. ALV-J strain SCAU-HN06 did not induce any significant antiviral innate immune response in 1 week old chicks. However, interferon-stimulated genes were not induced normally during the late phase of ALV-J infection due to a reduction of IRF1 and STAT1 expression. PMID:27252695

    Epithelioid hemangioma (EH) is a unique benign vasoformative tumor composed of epithelioid endothelial cells. Although a small subset of EHs with atypical features harbor ZFP36-FOSB fusions, no additional genetic abnormalities have been found to date in the remaining cases. On the basis of a novel FOS-LMNA gene fusion identified by RNA sequencing in an index case of a skeletal EH with typical morphology, we sought to investigate the prevalence of FOS rearrangement in a large cohort of EHs. Thus 57 additional EH cases lacking FOSB rearrangements were studied for FOS gene abnormalities by fluorescence in situ hybridization, and results were correlated with morphologic appearance and clinical presentation. The EHs were subclassified as typical (n=25), cellular (n=21), and angiolymphoid hyperplasia with eosinophilia (ALHE) (n=12) variants. The ALHE was defined as an EH with a vascular "blow-out" pattern associated with a variable degree of inflammation. There were 17 (29%) cases bearing FOS gene rearrangements among 58 cases tested, including 12 male and 5 female patients, with a mean age of 42 years. Most FOS-rearranged EHs occurred in the bone (10) and soft tissue (6), whereas only 1 case was cutaneous. The predominant anatomic site was the extremity (12), followed by trunk (3), head and neck (1), and penis (1). The incidence of FOS rearrangement was significantly higher in bone (59%, P=0.006) and lower in head and neck (5%, P=0.009). Twelve of the FOS-rearranged cases were cellular EH (P=0.001) associated with moderate mitotic activity (2 to 5/10 HPF) and milder inflammatory background. All 12 ALHE cases lacked FOS gene abnormalities, suggesting different pathogenesis. In conclusion, FOS rearrangement was present in a third of EHs across different locations and histologic variants; however, it was more prevalent in cellular EH and intraosseous lesions, compared with those in skin, soft tissue, and head and neck. This genetic abnormality can be useful in challenging

    We report the case of a young female patient with a diffuse choroidal hemangioma (DCH) and glaucoma as part of Sturge-Weber syndrome (SWS) and symptomatic retinal detachment that was treated successfully with photodynamic therapy (PDT) and intravitreal bevacizumab (IVB). The patient was treated with a single session of PDT, a 689-nm laser was used to deliver 50J/cm(2) with a maximum spot size of 6400μm, for 166s. IVB was administered 3 days later. The exudative retinal detachment (ERD), macular edema and visual acuity improved one week after treatment. The patient was followed for 18 months with no recurrence of ERD, and her visual acuity was preserved. PDT followed by IVB may be an effective treatment option for visual deterioration due to ERD in patients with DCHs, as are found in SWS. PMID:25560419

    The vascular origin lesions of the liver (capillary hemangioma/infantile hemangioendothelioma) that present in infancy or early childhood often have a typical clinical picture of hepatomegaly and congestive heart failure. These lesions rarely present as asymptomatic hepatomegaly, simulating a primary hepatic malignancy. These lesions may also simulate a primary or secondary hepatic malignancy on cross-sectional imaging or angiography. Scintigraphic evaluations with technetium-99m-labeled red blood cells offers an accurate method of identification of these lesions, and allows differentiation from other common primary or secondary hepatic masses in infancy or childhood. This scintigraphic method may also be used to follow these patients after medical, radiation, or embolization therapy. Experience with seven patients with these tumors is reported and compared with eight children with other primary or secondary liver tumors also evaluated by this method.

    The aim of the study is the assessment of the value of SPECT (single photon emission computerized tomography) using 99mTc-labeled red blood cells in the detection of liver hemangioma, in comparison to planar imaging. With planar red blood cell scintigraphy, sensitivity of the method was 76%, specificity 98%, positive predictive value 98% and negative predictive value 79%. With SPECT, sensitivity of the method was 95%, specificity 98%, positive predictive value 98% and negative predictive value 94%. The smallest lesion detected by planar red blood cell scintigraphy was 1.2 cm, and with SPECT red blood cell scintigraphy 0.8 cm. The use of 99mTc-labeled red blood cells SPECT improved the sensitivity much more in smaller lesions (0.8 to 2 cm), than in bigger ones (2-5 cm). SPECT with radiolabeled red blood cells significantlyy improves the results of scintigraphic findings, especially in the small lesions. PMID:19245136

    A 60 year old symptom free female in whom a lesion in left adrenal gland was found by chance in a CT scan is presented. She also had increased serum and urine catecholamines levels. 123I-MIBG scintigraphy showed a non-physiological uptake in right adrenal gland that is still seen in the delayed image, with normal left gland. MRI confirmed the presence of a mass in the left adrenal gland suggestive of an adenoma and found a lesion in the right hepatic area at the level of the previously seen MIBG image. This lesion was labelled as a hemangioma and would explain the findings of the isotopic study with MIBG. It must be considered as a false positive for phaechromocytoma. The increased catecholamine serum and urine levels were due to drug interactions. PMID:15847786

    Background Adenoma of the retinal pigment epithelium (RPE) is a rare intraocular tumor that can simulate other pigmented tumors such as choroidal melanoma. We report a case of non-pigmented adenoma of the RPE initially diagnosed as choroidal hemangioma. Case report A 42-year-old woman presented to Kurume University Hospital in November 1992 with an orange-yellow tumor nasal to the optic disc in the left fundus. The tumor was 9.0 × 9.0 mm in diameter, 6.0 mm thick, and was characterized by high intensity on T1-weighted magnetic resonance imaging (MRI), low intensity on T2-weighted MRI, and enhancement on gadolinium MRI. Fluorescein angiography revealed early hypofluorescence and late hyperfluorescence of the tumor and retinal feeder vessels. By April 1996, exudate had developed around the tumor margins. The patient was treated with external beam radiation therapy (20 Gy) in July 1996, but the tumor did not diminish in size. Subsequently, she developed extensive loss of vision due to total retinal detachment. Accordingly, her left eye was enucleated in June 2005 because of severe ocular pain due to absolute glaucoma. Histopathological examination indicated that the tumor was contiguous with the normal surrounding RPE and was composed of cords and tubules of mostly non-pigmented spindle-shaped cells with round to oval nuclei and a small amount of cytoplasm containing melanin granules. The tumor cells were immunoreactive for vimentin, S-100 protein, and cytokeratin 18. The final diagnosis was adenoma of the RPE. Conclusion Adenoma of the retinal pigment epithelium may be associated with incompetent vessels leading to serous retinal detachment and extensive visual loss, and may exhibit clinical characteristics similar to choroidal hemangioma.

    Pulsed dye lasers (PDL) are the standard of care in the treatment of cutaneous vascular disorders such as the port-wine strains or hemangiomas of infancy. Nonetheless, there is still uncertainty regarding the specific laser parameters that are likely to yield optimal clinical outcomes. Using mathematical modeling, we explain and associate clinical outcomes with laser wavelength, radiant exposure, and pulse time and shape. The model's prediction that a continuous PDL pulse of 0.45 ms with a radiant exposure of 6 J/cm(2) is equivalent to delivering a 1.5-ms pulse consisting of three pulses with a radiant exposure of 12 J/cm(2) is in agreement with clinical studies. The model also suggests that for vascular malformations involving vessel diameters in the range of 150-500 microm, one should use a PDL at a wavelength of 595 nm with a radiant exposure of at least 12 J/cm(2) and pulse time of 1.5 ms, delivered in three pulses. Whereas it is calculated that malformations with vessels smaller than 50 microm will not respond to PDL in any clinical setting, an excellent response to PDL treatment at either a 585- or 595-nm wavelength can be expected for malformations with vessel diameters of 50-150 microm. Epidermal cooling is highly recommended for all settings to minimize pain and the risk of side effects. Finally, the model is used to generate a reference table that suggests specific PDL parameters for the treatment of various malformations and hemangiomas. The table cannot replace a clinician's experience with respect to which and how parameters should be changed, but provides a defined window of parameters that should be tried to improve clinical response.

    Objective To evaluate the efficacy and adverse effects of interferon-α2a in the treatment of alarming infantile hemangiomas in the head and neck region. Patients and methods From January 2009–December 2010, a subcutaneous injection of interferon-α2a was applied to eleven infants with giant multifocal or segmental hemangiomas at a dose of 3 million units/m2 per day. All patients did not respond to propranolol or corticosteroids. The age at initiation of interferon-α2a therapy ranged from 3 days to 8 months (median: 4 months). The duration of therapy ranged from 2–4.5 months (median: 3 months). Eight patients received medication for 3 months, one patient for 4.5 months, and two patients for 2 months. Results Nine patients had a reduction in tumor mass of 95%; two patients’ tumors decreased in size by 75%. The overall response rate was 100%. The main adverse effects included fever, diarrhea, and anorexia, which resolved after stopping the medication. No serious adverse effect was observed. Conclusion Short-term treatment with interferon-α2a can be used as a safe and effective treatment for alarming infantile hemangiomas that are resistant to propranolol or corticosteroids, and that endanger the proper functioning of the affected organ or the patient’s life.

    Purpose The purpose of this study was to report a case of Von Hippel-Lindau disease (VHL) with twin retinal capillary hemangiomas that was successfully treated by vitreous surgery for tractional retinal detachment following laser photocoagulation. Case A 44-year-old male presented at our university hospital after noticing decreased visual acuity in his right eye. The patient had previously undergone multiple operations for cerebellar, thoracic, and lumbar spine hemangioblastomas when he was approximately 19 years old. Upon initial examination, ocular findings revealed twin connected retinal capillary hemangiomas around the temporal upper area of the patient's right eye. The patient was subsequently diagnosed with VHL based on his medical history and current observations of the ocular fundus. Tractional retinal detachment had occurred as the result of the formation of proliferative membranes following laser photocoagulation. The patient underwent vitreous surgery to treat the tractional retinal detachment, resulting in a successful postoperative outcome. Conclusion The findings of this study show the possibility that proliferative changes and tractional retinal detachment can arise following photocoagulation for retinal capillary hemangiomas in patients with VHL.

    Spindle cell hemangioma (SCH) is a rare, benign vascular tumor of the dermis and subcutis. The lesions can be multifocal and are overrepresented in Maffucci syndrome, in which patients also have multiple enchondromas. Somatic mosaic R132C IDH1 hotspot mutations were recently identified in Maffucci syndrome. We evaluated the presence of mutations in solitary and multiple SCHs in patients without multiple enchondromas and tested a range of other vascular lesions that enter into the differential diagnosis. The R132C IDH1 mutation was identified by hydrolysis probes assay and confirmed by Sanger sequencing in 18 of 28 (64%) SCHs; of the 10 negative cases, 2 harbored a mutation in IDH2 (R172T and R172M) by Sanger sequencing. None of 154 other vascular malformations and tumors harbored an IDH1 R132C mutation, and R132H IDH1 mutations were absent in all 182 cases. All 16 SCHs examined by immunohistochemistry were negative for expression of HIF-1α. In conclusion, 20 of 28 (71%) SCHs harbored mutations in exon 4 of IDH1 or IDH2. Given that mutations were absent in 154 other vascular lesions, the mutation seems to be highly specific for SCH. The mutation does not induce expression of HIF-1α in SCH, and therefore the exact mechanism by which mutations in IDH1 or IDH2 lead to vascular tumorigenesis remains to be established. PMID:23485734

    Ollier disease and Maffucci syndrome are non-hereditary skeletal disorders characterized by multiple enchondromas (Ollier disease) combined with spindle cell hemangiomas (Maffucci syndrome). We report somatic heterozygous mutations in IDH1 (c.394C>T encoding an R132C substitution and c.395G>A encoding an R132H substitution) or IDH2 (c.516G>C encoding R172S) in 87% of enchondromas (benign cartilage tumors) and in 70% of spindle cell hemangiomas (benign vascular lesions). In total, 35 of 43 (81%) subjects with Ollier disease and 10 of 13 (77%) with Maffucci syndrome carried IDH1 (98%) or IDH2 (2%) mutations in their tumors. Fourteen of 16 subjects had identical mutations in separate lesions. Immunohistochemistry to detect mutant IDH1 R132H protein suggested intraneoplastic and somatic mosaicism. IDH1 mutations in cartilage tumors were associated with hypermethylation and downregulated expression of several genes. Mutations were also found in 40% of solitary central cartilaginous tumors and in four chondrosarcoma cell lines, which will enable functional studies to assess the role of IDH1 and IDH2 mutations in tumor formation.

    Voluminous vascular anomalies of the head and neck region are still treated with conventional surgery although Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser therapy is an effective treatment method. One hundred thirty give patients with voluminous hemangiomas and vascular malformations were treated with interstitial Nd:YAG laser therapy, partly complemented by a non-contact mode Nd:YAG laser light application. The vascular tumors had a diameter of more than 3 cm in two or all three dimensions. Treatment was carried out under ultrasound and manual control. Nearly 60% of the patients showed a complete clinical regression of the vascular tumor, a third of the patients had a partial regression and were satisfied with the treatment outcome. Four patients were treated unsuccessfully with the laser and three of them subsequently underwent conventional surgery. Only 10 patients showed cosmetic and functional deficits. These results on the interstitial Nd:YAG laser therapy of voluminous hemangiomas and vascular malformations in a large patient group demonstrated the high effectiveness of this novel and innovative therapy modality.

    Background: Infantile hemangioma (IH) is the most common tumor during infancy that usually appears as macular and gradually becomes a plaque or tumor. Approximately, 20% of all IH cases results in adverse effects and the Pulsed dye laser (PDL) 585 nm is a vascular laser leading to selective the micro vascular damage. Results of studies on non-selective B-blockers (e.g., timolol) indicate their effectiveness in preventing hemangioma growth. The aim of this study is a comparison of PDL plus timolol and PDL in the treatment of IH. Materials and Methods: This double-blind study was carried out on 30 infants (1-12 months old) and the patients were divided into two groups. Group A was treated with the four sessions PDL and the timolol gel 0.05% and Group B with PDL. Results: There were no differences in the mean age of patients for the diagnosis of hemangioma (Group A: 32.69 ± 24.64 days, Group B: 25.69 ± 21.16 days, P = 0.39) and the mean age at the start of the treatment (Group A: 148.125 ± 85.88 days, Group B: 146.25 ± 60.87 days, P = 0.94). There were a statistical difference in the mean of lesion size reduction (Group A: 17.62 ± 6.97 cm and Group B: 12 ± 5.71 cm, P = 0.018), mean percentage change in size mean (Group A: 71079 ± 23.41% and Group B: 54.59 ± 25.46%, P = 0.050) visual analog scale (Group A: 7.19 ± 1.51, Group B: 5.62 ± 1.78, P = 0.012) after treatment. There was no correlation between the time of beginning the treatment and the results (P = 0.857). Conclusions: Application of timolol with PDL is accompanied by the highest efficacy, cost benefits and the short time of treatment. PMID:26918239

    Cavernous angiomas originating in the internal auditory canal are very rare. In the available literature, only 65 cases of cavernomas in this location have been previously reported. We describe the case of a 22-year-old woman surgically treated for a cavernous hemangioma in the left internal auditory canal, mimicking on preoperative magnetic resonance imaging MRI an acoustic neuroma. Neurological symptoms were hypoacusia and dizziness. The cavernous angioma encased the seventh and, partially, the eighth cranial nerve complex. A "nearly total" removal was performed, leaving a thin residual of malformation adherent to the facial nerve. Postoperative period was uneventful; hearing was unchanged, but the patient had a moderate inferior left facial palsy (House-Brackmann grade II) slightly improved during the following weeks. On the basis of the observation of this uncommon case, we propose a revision of the literature and discuss clinical features, differential diagnosis, and treatment. PMID:26876892

    RNA-sequencing of a splenic hemangioma with the karyotype 45~47,XX,t(3;6)(q26;p21) showed that this translocation generated a chimeric TBL1XR1-HMGA1 gene. This is the first time that this tumor has been subjected to genetic analysis, but the finding of an acquired clonal chromosome abnormality in cells cultured from the lesion and the presence of the TBL1XR1-HMGA1 fusion in them strongly favor the conclusion that splenic hemangiomas are of a neoplastic nature. Genomic PCR confirmed the presence of the TBL1XR1-HMGA1 fusion gene, and RT-PCR together with Sanger sequencing verified the presence of the fusion transcripts. The molecular consequences of the t(3;6) would be substantial. The cells carrying the translocation would retain only one functional copy of the wild-type TBL1XR1 gene while the other, rearranged allele could produce a putative truncated form of TBL1XR1 protein containing the LiSH and F-box-like domains. In the TBL1XR1-HMGA1 fusion transcript, furthermore, untranslated exons of HMGA1 are replaced by the first 5 exons of the TBL1XR1 gene. The result is that the entire coding region of HMGA1 comes under the control of the TBL1XR1 promoter, bringing about dysregulation of HMGA1. This is reminiscent of similar pathogenetic mechanisms involving high mobility genes in benign connective tissue tumors such as lipomas and leiomyomas. PMID:26708416

    Clinical and histopathological features were investigated in 43 cases of oral lobular capillary hemangiomas (LCH) with a special reference to characteristics of the vascular elements. The lesions affected females more than males by a ratio of 1:1.5. Average age of the patients was 52.7 years. The lesions involved the gingiva (n = 15), the tongue (n = 13), the labial mucosa (n = 10) and other sites. The lesions appeared usually as a pedunculated mass with ulceration; size of the lesions was up to 15 mm. Histologically, a lobular area and an ulcerative area were distinguished. The density of vessels was about 1045/mm2 and 160/mm2 in the lobular and ulcerative areas, respectively. The average diameter of the vascular lumen was 9.1 5.6 mm (range: 2.8-42.0 mm) and 18.8 20.9 mm (range: 5.6-139.7 mm) in the lobular and ulcerative areas, respectively. In the lobular area, most of the vessels had an inner layer of endothelial cells showing positive reaction for von Willebrand factor (vWF) and CD34, as well as an outer layer of mesenchymal cells showing positive reaction for alpha-smooth muscle actin (ASMA). However, in the ulcerative area, there was a variety of types of vessels consisting of various proportions of both endothelial and ASMA-positive perivascular mesenchymal cells. These results indicate that most of the vascular elements in the lobular area resemble more pericapillary microvascular segments than they do capillaries. Thus, the authors propose the term 'lobular pericapillary hemangioma' to represent this type of lesion. PMID:12558863

    Purpose To determine the efficacy and safety of oral propranolol as a first-line treatment for superficially located infantile hemangioma (IH) and propose an assessment tool to measure treatment response. Methods Patients with superficial IH under 1 year of age were prospectively recruited between May 2012 and December 2013 at the Department of Pediatrics of Chungbuk National University Hospital. Propranolol was administered to 12 infants (median age, 3.8 months) while monitoring cardiovascular and adverse metabolic effects. If a patient showed no adverse events, the dosage was gradually increased up to 3 mg/kg/day and maintained for 1 year. We used our own scoring system to assess treatment response using parameters like change in color, and longest diameter, and thickness of the IH. Results Eleven out of 12 patients completed the protocol with consistent improvement of hemangiomas during therapy. Patients on propranolol showed a more than 50% involution in the first 3 months, with additional steady involution until 1 year. Patients with the highest scores at 1 month maintained their score and showed better responses until treatment termination. The patient with the lowest score at 1 month did not show any further regression and stopped propranolol treatment 4 months after initiation. In two children with recurrences after successful therapeutic regression, propranolol was effective after being reintroduced. Propranolol treatment was not interrupted in any patient due to adverse events. Conclusion Oral propranolol at 3 mg/kg/day showed a consistent, rapid, and therapeutic effect on superficial IHs without significant adverse events. PMID:26770224

    Cryotherapy is the application of varying extremes of cold temperatures to destroy abnormal tissue. The intent of this article is to describe a novel technique using percutaneous cryotherapy for treating a noninvoluting congenital craniofacial hemangioma (NICH). An 18-year-old woman with type 1 von Willebrand's disease, as well as a qualitative platelet aggregation disorder, presented with multiple recurrent episodes of oral bleeding from a NICH involving the right buccal space and maxillary tuberosity. The patient was initially treated with a combination of endovascular particulate embolization, percutaneous sclerotherapy, tissue cauterization, and laser therapy between the ages of 4 and 8 years of age. At 18 years of age, the patient presented with recurrent episodes of oral bleeding related to the NICH. Endovascular embolization was performed using particulate and a liquid embolic agent with limited success. Due to the refractory nature of this bleeding, the patient underwent successful lesion ablation using percutaneous cryotherapy. At 9-month follow-up, the patient is asymptomatic with no episodes of recurrent bleeding.

    Background: Cerebral cavernous malformations (CCMs) are angiographically occult vascular malformations of the central nervous system. As a result of hemorrhage and mass effect, patients may present with focal neurologic deficits, seizures, and other symptoms necessitating treatment. Once symptomatic, most often from hemorrhage, CCMs are treated with microsurgical resection. Orbital cavernous hemangiomas (OCHs) are similar but distinct vascular malformations that present within the orbital cavity. Even though CCMs and OCHs are both marked by dilated endothelial-lined vascular channels, they are infrequently seen in the same patient. Case Description: We provide a brief overview of the two related pathologies in the context of a patient presenting to our care with concomitant lesions, which were both resected in full without complication. Conclusion: This is the first known report that describes a case of concomitant CCM and OCH and explores the origins of two pathologies that are rarely encountered together in neurosurgical practice. Recognition of disparate symptomatologies is important for properly managing these patients. PMID:25071938

    Infantile hemangioma (IH) is the most common tumor of the pediatric age group, affecting up to 4% of newborns ranging from inconsequential blemishes, to highly aggressive tumors. Following well defined growth phases (proliferative, plateau involutional) IH usually regress into a fibro-fatty residuum. Despite the high prevalence of IH, little is known regarding the pathogenesis of disease. A reported six fold decrease in IGF2 expression (correlating with transformation of proliferative to involuted lesions) prompted us to study the IGF-2 axis further. We demonstrate that IGF2 expression in IH is strongly related to the expression of a cancer testes and suspected oncogene BORIS (paralog of CTCF), placing IH in the unique category of being the first known benign BORIS positive tumor. IGF2 expression was strongly and positively related to BORIS transcript expression. Furthermore, a stronger association was made when comparing BORIS levels against the expression of CTCF via either a percentage or difference between the two. A common C/T polymorphism at CTCF BS6 appeared to modify the correlation between CTCF/BORIS and IGF2 expression in a parent of origin specific manner. Moreover, these effects may have phenotypic consequences as tumor growth also correlates with the genotype at CTCF BS6. This may provide a framework for explaining the clinical variability seen in IH and suggests new insights regarding CTCF and BORIS related functionality in both normal and malignant states.

    Gankyrin (also called p28 or PSMD10) is an oncoprotein commonly overexpressed in hepatocellular carcinomas. It consists of 7 ankyrin repeats and interacts with multiple proteins including Rb, Cdk4, MDM2 and NF-κB. To assess the oncogenic activity in vivo, we produced transgenic mice that overexpress gankyrin specifically in the hepatocytes. Unexpectedly, 5 of 7 F2 transgenic mice overexpressing hepatitis B virus X protein (HBX) promoter-driven gankyrin, and one of 3 founder mice overexpressing serum amyloid P component (SAP) promoter-driven gankyrin developed hepatic vascular neoplasms (hemangioma/hemangiosarcomas) whereas none of the wild-type mice did. Endothelial overgrowth was more frequent in the livers of diethylnitrosamine-treated transgenic mice than wild-type mice. Mouse hepatoma Hepa1-6 cells overexpressing gankyrin formed tumors with more vascularity than parental Hepa1-6 cells in the transplanted mouse skin. We found that gankyrin binds to and sequester factor inhibiting hypoxia-inducible factor-1 (FIH-1), which results in decreased interaction between FIH-1 and hypoxia-inducible factor-1α (HIF-1α) and increased activity of HIF-1 to promote VEGF production. The effects of gankyrin were more prominent under 3% O2 than 1% or 20% O2 conditions. Thus, the present study clarified, at least partly, mechanisms of vascular tumorigenesis, and suggests that gankyrin might play a physiological role in hypoxic responses besides its roles as an oncoprotein.

    Twelve patients with the histologic diagnosis of soft-tissue hemangioma of the extremities (nine intramuscular, two subcutaneous, and one synovial) were evaluated in a retrospective study using plain film radiography (n = 12), angiography (n = 8), computed tomography (CT; n = 4), magnetic resonance imaging (MRI; n = 3), and ultrasonography (US; n = 2). In eight of nine intramuscular lesions, the plain film demonstration of phleboliths suggested the diagnosis, while the plain radiographs were normal in three. Angiograms showed the pathognomonic features of soft-tissue hemangioma in six patients. MRI was characteristic in all three patients: The lesion demonstrated intermediate signal intensity on T1-weighted spin echo images and extremely bright signal on T2-weighting. US showed a hypoechoic soft-tissue mass in one case and a mixed echo pattern in the other. In one case, a central echogenic focus with acoustic shadowing consistent with a calcified phlebolith was identified, and one lesion exhibited increased color flow and low resistance arterial Doppler signal. CT showed a nonspecific mass in one of four cases and a mass with phleboliths in three. If a deep hemangioma is suspected, we recommend initial imaging with plain radiography followed by MRI. US may be useful in confirming the presence of a mass in doubtful cases or if MRI is unavailable. CT offers no distinct advantage over the combined use of plain radiography and MRI. Although angiography demonstrated the pathognomonic features in all six deeply situated lesions, because of its invasiveness it should be reserved chiefly for those patients undergoing surgical resection.

    The aim of the present study was to investigate the clinical efficacy and safety of low-dose 90Sr-90Y therapy combined with the topical application of 0.5% timolol maleate solution for the treatment of superficial infantile hemangiomas (IHs). A total of 72 infants with hemangiomas were allocated at random into the observation group (17 cases aged ≤3 months, 20 cases aged >3 months) or the control group (15 cases aged ≤3 months, 20 cases aged >3 months). The observation group was treated with low-dose 90Sr-90Y combined with timolol, while the control group received an identical dose of 90Sr-90Y with physiological saline. Data were collected for statistical analysis, and treatment efficacy was compared between the two groups. In the observation group, 100% (37/37) of subjects exhibited an ‘excellent’ response to the treatment, while 94.1% (16/17) of patients aged ≤3 months and 85.0% (17/20) aged >3 months were classed as being cured. In the control group, the treatment was classed as ‘effective’ in 100% (35/35) of the subjects, while the excellent response rate was 86.7% (13/15) among the infants aged ≤3 months and 75.0% (15/20) among the infants aged >3 months. The ‘cure’ rates in the control group were 66.7% (10/15) and 60.0% (12/20) for the ≤3-month- and >3-month-old subjects, respectively. The excellent response and cure rates were notably higher in the observation group than those in the control group. Comparison between the two groups revealed a χ2 value of 13.90 (P<0.01) for excellent responses in subjects aged ≤3 months, while for patients aged >3 months the χ2 value was 28.57 (P<0.01). Analysis of the cure responses gave similar results [≤3 months, χ2=23.22 (P<0.01); >3 months, χ2=15.67 (P<0.01)]. At 3–4 months after the first course of treatment, the cure rate was 33.3% (11/33) in the observation group, which was significantly higher than the rate of 18.32% (4/22) in the control group (χ2=5.92, P<0.05).

    Hepatic sinusoid plays a vital role in human cavernous hemangioma of the liver (CHL), and its morphologic investigation facilitates the understanding of microcirculation mechanism and pathological change of CHL. However, precise anatomical view of the hepatic sinusoid has been limited by the resolution and contrast available from existing imaging techniques. While liver biopsy has traditionally been the reliable method for the assessment of hepatic sinusoids, the invasiveness and sampling error are its inherent limitations. In this study, imaging of CHL samples was performed using in-line phase-contrast imaging (ILPCI) technique with synchrotron radiation. ILPCI allowed clear visualization of soft tissues and revealed structural details that were invisible to conventional radiography. Combining the computed tomography (CT) technique, ILPCI-CT was used to acquire the high-resolution micro-CT images of CHL, and three dimensional (3D) microstructures of hepatic sinusoids were provided for the morphologic depiction and quantitative assessment. Our study demonstrated that ILPCI-CT could substantially improve the radiographic contrast of CHL tissues in vitro with no contrast agent. ILPCI-CT yielded high-resolution micro-CT image of CHL sample at the micron scale, corresponding to information on actual structures revealed at histological section. The 3D visualization provided an excellent view of the hepatic sinusoid. The accurate view of individual hepatic sinusoid was achieved. The valuable morphological parameters of hepatic sinusoids, such as thrombi, diameters, surface areas and volumes, were measured. These parameters were of great importance in the evaluation of CHL, and they provided quantitative descriptors that characterized anatomical properties and pathological features of hepatic sinusoids. The results highlight the high degree of sensitivity of the ILPCI-CT technique and demonstrate the feasibility of accurate visualization of hepatic sinusoids. Moreover

    Clonal endothelial progenitor cells (EPCs) have been implicated in the aberrant vascular growth that features infantile hemangioma (IH), the most common benign vascular tumor in childhood that may cause ulceration, bleeding, and/or permanent disfigurement. Endothelial colony-forming cells (ECFCs), truly endothelial EPCs endowed with clonal ability and capable of forming patent vessels in vivo, remodel their Ca(2+) toolkit in tumor-derived patients to acquire an adaptive advantage. Particularly, they upregulate the proangiogenic store-operated Ca(2+) entry (SOCE) pathway due to the overexpression of its underlying components, that is, stromal interaction molecule 1 (Stim1), Orai1, and transient receptor potential canonical 1 (TRPC1). The present work was undertaken to assess whether and how the Ca(2+) signalosome is altered in IH-ECFCs by employing Ca(2+) and nitric oxide (NO) imaging, real-time polymerase chain reaction, western blotting, and functional assays. IH-ECFCs display a lower intracellular Ca(2+) release in response to either pharmacological (i.e., cyclopiazonic acid) or physiological (i.e., ATP and vascular endothelial growth factor) stimulation. Conversely, Stim1, Orai1, and TRPC1 transcripts and proteins are normally expressed in these cells and mediate a constitutive SOCE, which is sensitive to BTP-2, La(3+), and Pyr6 and recharges the intracellular Ca(2+) pool. The resting SOCE in IH-ECFCs is also associated to an increase in their proliferation rate and the basal production of NO compared to normal cells. Likewise, the pharmacological blockade of SOCE and NO synthesis block IH-ECFC growth. Collectively, these data indicate that the constitutive SOCE activation enhances IH-ECFC proliferation by augmenting basal NO production and sheds novel light on the molecular mechanisms of IH.

    Background Infantile hemangiomas (IH) are common benign vascular tumors in children. Recognition and timely referral of high risk IH to specialized centers is important. This might be achieved by involving parents in the care for IH by means of an eHealth intervention. Objective The objective of our study was to evaluate parent compliance, acceptance, and usability of an open access, Web-based eHealth intervention (including e-learning and e-consult) designed to increase parents’ knowledge and (risk) evaluation of IH. Methods A cross-sectional study of parents who completed the eHealth intervention between October 2010 and November 2012 was carried out. All parents were sent a study questionnaire. Questions to evaluate compliance (to the advice given by a dermatologist during e-consultation) were asked. Acceptance and usability were evaluated by using the modified Technology Acceptance Model. Results A total of 224 parents completed the eHealth intervention and received the questionnaire, 135/224 parents responded (response rate was 60.3%). There were 128/135 questionnaires that were completed and included. A total of 110/128 (85.9%) parents were compliant to the advice of the dermatologist. There were 116.8/128 (91.3%) that perceived the eHealth intervention as useful and almost all parents (98.4%, 126/128) found the information in the e-learning clear. There were 29/128 (22.7%) that experienced technical problems. The majority of the parents (94.5%, 121/128) found the eHealth intervention reliable and most of them (98.4%, 126/128) would recommend the eHealth intervention to other parents. Noncompliant parents judged the eHealth intervention significantly less reliable compared to compliant parents (71%, 10/14 versus 97.3%, 107/110; P=.003). Conclusions Parents of children with an IH showed a high compliance (85.9%, 110/128) to the advice of the dermatologist given via our Web-based eHealth intervention. This high compliance might be positively influenced by the

    Background: Primary intraosseous cavernous hemangiomas (PICH) of the skull represent an infrequent bone tumor. Although some rare cases of PICHs located in the skull base have been published, to our concern only three cases have been reported in the English literature of PICHs arising within the clivus. Case Description: We present the case of a patient presenting an isolated abducens paresis due to a rare PICH of the clivus showing also an unusual destruction of the inner table as well as infiltration of the dura mater. Due to this uncommon infiltrative pattern of an otherwise expected intraosseous tumor, a cerebrospinal fluid (CSF)-fistula occurred while performing a transnasal biopsy. The patient recovered successfully without need of lumbar drainage or re-surgery. Additionally, intratumoral decompression was sufficient to relief the abducens paresis. Conclusions: Our case provides new and meaningful information about clinical features as well as growth pattern of these rare clival tumors. We also discuss the importance of knowing these peculiarities before surgery in order to plan the optimal operative management as well as to avoid complications while approaching PICHs localized in such a delicate cranial region.

    The widespread application of array comparative genomic hybridization (aCGH) has provided new insights into the clinical significance of copy number variations (CNVs) in the human genome. Many microdeletion syndromes have recently been linked to corresponding reciprocal microduplication syndromes related to CNVs in the same chromosomal regions. However, the extent of CNVs may not be restricted to only microduplications but may also include microtriplications or even quadruplications. 4q21 microdeletion syndrome is one of these recently described syndromes. The phenotype includes growth restriction, neonatal hypotonia, severe developmental delay, absent or delayed speech, and distinct facial features. The minimal critical deleted region, which is 1.3 Mb in size, contains the PRKG2, RASGEF1B, HNRNPD, HNRPDL, and ENOPH1 genes. Here, we report a 5.4-year-old girl with developmental delay, absence of speech, muscular hypertension, macrocephaly, a broad forehead, frontal bossing, relatively elongated extremities, a vascular malignant hemangioma in anamnesis, and elongated sigmoid colon. aCGH revealed a microtriplication at 4q21.21-q21.22 that was 1.61 Mb in size. This de novo microtriplication included nine genes (BMP3, PRKG2, RASGEF1B, HNRNPD, HNRPDL, ENOPH1, TMEM150C, LINC00575, and SCD5) and overlapped with the minimal critical region for 4q21 microdeletion syndrome. Some clinical features of the patient were similar to those of 4q21 microdeletion (macrocephaly, frontal bossing, developmental delay, absence of speech, and anxiety), whereas others were mirrored (elongated extremities and muscular hypertension). The first identified case of a de novo microtriplication at 4q21.21-q21.22 emphasizes the clinical significance of CNVs at 4q21 for patients with developmental delay and absence of speech. © 2016 Wiley Periodicals, Inc.

    Neoplastic lesions of the fallopian tube are rarely seen by surgical pathologists. Haemangioma of the fallopian tube is an extremely rare benign neoplasm. A 30-year-old lady with polymenorrhea and dysmenorrhea underwent hysterectomy and bilateral salpingo-oophorectomy. Her left fallopian tube showed a 2mm sized solid nodule in the wall. Histopathological examination revealed a well-defined vascular lesion in the left fallopian tube, consistent with capillary haemangioma. The vascular endothelium was highlighted by CD34 immunostaining. Our literature review has identified 10 cases of cavernous haemangioma of the fallopian tube. To the best of our knowledge, we report the first ever case of capillary haemangioma of the fallopian tube. This is also the smallest detected haemangioma in the fallopian tube. PMID:27190899

    The authors relate on a case of an isolated cavernous haemangioma of the body of the tongue characterized by considerable size. Such neoplasms, usually described within the more extensive chapter of the more common angiomatous lesion of the oral cavity, are relatively rare. The authors describe a personal case discussing the diagnostic spects of such lesion and emphasizing the importance of the arteriography of the carotid artery and the of the selective arteriography of the lingual arteries, especially in considering surgery. Biopsies are not recommended. After discussing the histopathological and clinical aspects of such lesions the Authors emphasize the therapeutic ones. Even though radiotherapy, cryotherapy, laser therapy, medical treatment, injection of sclerosing substances and the selective embolization, of the lingual artery seem to have some efficacy, the authors conclude that surgery in the therapy of choice in the isolated vascular lesions of the body of the tongue.

    A 14-year-girl presented with solitary exuberant warty plaque over her right great toe since the age of 4 years. Ten years ago, an excisional biopsy was performed by a surgeon, and a histopathological diagnosis of angiokeratoma was made. A wide local excision of the lesion followed by a plantar digital artery flap in a V-Y fashion adjacent and just proximal to the excision wound was performed. This procedure has not only led to complete growth removal, but also a well-preserved digit with an excellent color and contour match. PMID:21430831

    A rare neoplasm, termed ‘anastomosing hemangioma’ (AH), has been previously described in the genitourinary tract. To date, 29 cases of AH have been reported in the literature, and the case reported in the present study is, to the best of our knowledge, the first AH described in the urinary bladder. It is essential to distinguish AH from malignant vascular tumors due to the different treatments required and the prognosis. The patient in this case study was asymptomatic, with a neoplasm of ~1 cm within the right wall of the bladder. Pathologically, the lesion was predominantly composed of a structure comprising a small vascular cavity and irregularly fenestrated anastomosing vascular channels, with no clear atypia of the endothelial cells.

    A 20-day-old boy presented for evaluation of a blue nodule on the right shoulder that had been present since birth. The mother noted no changes in the size of the lesion since birth, and no bleeding or ulceration was noted. The patient's past medical history was unremarkable. He was a full-term baby born at 39 weeks gestation via a normal, spontaneous vaginal delivery. The pregnancy was uncomplicated. The mother had no history of maternal hypertension and had no history of chorionic villus sampling or amniocentesis. The patient was not taking any medications and had no known allergies. Physical exam revealed a well-developed, well-nourished male in no apparent distress. A full skin exam revealed a 1.8 cm × 2 cm discrete, blue-purple vascular nodule with coarse surface telangiectasias and a surrounding rim of pallor on the right shoulder. There was no bleeding or breakdown noted. There was no lymphadenopathy present. PMID:24549083

    Capillary Haemangioma is a benign vascular tumour characterized by proliferation of blood vessels that are primarily reported to be a developmental hamartomatous lesion of infancy and childhood. Pyogenic granuloma is a non-neoplastic benign lesion found in the oral cavity having a striking predilection for occurrence in the gingiva. The present case report is an atypical presentation of capillary haemangioma on gingiva which is considered to be extremely rare. The lesion in this case was clinically diagnosed as pyogenic granuloma but histopathologically as capillary haemangioma. These lesions present as a diagnostic dilemma to the clinician and can lead to serious complications if not carefully managed. PMID:26557632

    Laser therapy and in particular Nd:YAG laser therapy has become of increasing importance amongst the various methods of treating haemangiomas. Nd:YAG laser radiation penetrates deep into the tissue. To avoid undesirable results of treatment, certain treatment guidelines must be observed: to protect the tissue from serious heat damage, the Nd:YAG laser radiation should be applied exclusively with simultaneous tissue cooling. Depending on the location of the haemangioma, this is carried out with ice cubes (if possible, not containing air bubbles) or with an ice-cold Ringer solution. The depth of penetration of the laser radiation can be increased by tissue compression with a piece of ice or with a special glass disc. In very voluminous haemangiomas, the laser light is additionally applied via a bare fibre directly on to the vascular tissue. The laser power densities we use are between 500 and 3,000 watts/cm2. The power chosen depends on the tissue effect of the laser radiation. Blanching of the vascular tissue without carbonisation is aimed at. With consistent observance of the treatment guidelines specified, haemangiomas should be treated as early as possible with the Nd:YAG laser. The treatment principle of "wait and see" is often advocated, but we consider to be obsolete, since cosmetically and functionally unsatisfactory residual scars may remain even after complete haemangioma regression. Moreover, the progressive haemangiomas which often lead to complications cannot be distinguished from regressive haemangiomas. Last but not least, the child and the parents should be spared the (in some cases appreciable) psychological strain of a haemangioma. PMID:1388462

    Argon laser was applied in 172 patients with various vascular disorders and epidermal nevi. The best therapeutical results were obtained in facial telangiectasia and in cavernous hemangiomas, in which there was a complete or almost complete regression. In capillary facial hemangiomas in 49 patients (79%) clearing of 50% to 75% was obtained, and in epidermal nevi the full regression was in 4 (44%) of the cases, and 50% regression in 4 (44%). In telangiectasia of the lower limbs the results were not satisfactory. We stress that cavernous, and capillary hemangiomas, as well as facial telangiectasia are an indication for the argon laser therapy.

    Throughout the years, various classifications have evolved for the diagnosis of vascular anomalies. However, it remains difficult to classify a number of such lesions. Because all hemangiomas were previously considered to involute, if a lesion with imaging and clinical characteristics of hemangioma does not involute, then there is no subclass in which to classify such a lesion, as reported in one of our cases. The recent classification proposed by the International Society for the Study of Vascular Anomalies (ISSVA, 2014) has solved this problem by including non-involuting and partially involuting hemangioma in the classification. We present here five cases of vascular anomalies and discuss their diagnosis in accordance with the ISSVA (2014) classification. A non-involuting lesion should not always be diagnosed as a vascular malformation. A non-involuting lesion can be either a hemangioma or a vascular malformation depending upon its clinicopathologic and imaging characteristics. PMID:26125008

There was salmon stain in the nape in 61.7%, 15% in the forehead and in the superior eyelids 14.3%. The familiar antecedents of vascular nevus in brothers was of 4.76%, 5.71% in uncle, 2.98% in parents and 1.43% in grandparents. The evolution was not concluded because of desertion in almost the totality of patients, finalizing with only the 6.66%. Our findings are different from those published in the literature.

    Propranolol has recently emerged as an effective therapy for infantile hemangiomas causing regression. The β-adrenergic receptor (AR) antagonist is thought to cause vasoconstriction by its effect on nitric oxide, block angiogenesis by its effect on vascular endothelial growth factor (VEGF), and induce apoptosis. In a prior report, we identified expression of β2-AR (B2-AR) and its phosphorylated form (B2-ARP) in a case of infantile hemangioma that responded to propranolol treatment. We now explore the expression of βARs on a variety of vascular lesions utilizing a tissue microarray containing 141 lesions, including infantile hemangiomas, angiosarcomas, hemangiomas, hemangioendotheliomas, and various vascular malformations. The array was immunostained for B2-AR, B2-ARP, and β3-AR (B3-AR), and the results scored for the intensity of endothelial cell expression as negative, weak positive, or strong positive. All phases of infantile hemangiomas had strong expression of all three receptors, with the exception of only weak expression of B2-ARP in the proliferative phase infantile hemangioma. Strong expression of all three receptors was present in many hemangiomas, hemangioendotheliomas, and vascular malformations. Absent to weak expression of all three receptors was seen in glomus tumor, hobnail hemangioendothelioma, pyogenic granuloma, and reactive vascular proliferations. This is the first study to report β-AR expression in a variety of vascular lesions. Although immunohistochemical expression of the receptors does not necessarily indicate that similar pathways of responsiveness to β-blockade are present, it does raises the possibility that β-blockade could potentially affect apoptosis and decrease responsiveness to VEGF. Additional study is warranted, as therapeutic options are limited for some patients with these lesions. PMID:22743651

    Hemangiomas are the most common type of tumor in infants. As they are endothelial cell–derived neoplasias, their growth can be regulated by the autocrine-acting Tie2 ligand angiopoietin 2 (Ang2). Using an experimental model of human hemangiomas, in which polyoma middle T–transformed brain endothelial (bEnd) cells are grafted subcutaneously into nude mice, we compared hemangioma growth originating from bEnd cells derived from wild-type, Ang2+/–, and Ang2–/– mice. Surprisingly, Ang2-deficient bEnd cells formed endothelial tumors that grew rapidly and were devoid of the typical cavernous architecture of slow-growing Ang2-expressing hemangiomas, while Ang2+/– cells were greatly impaired in their in vivo growth. Gene array analysis identified a strong downregulation of NADPH oxidase 4 (Nox4) in Ang2+/– cells. Correspondingly, lentiviral silencing of Nox4 in an Ang2-sufficient bEnd cell line decreased Ang2 mRNA levels and greatly impaired hemangioma growth in vivo. Using a structure-based approach, we identified fulvenes as what we believe to be a novel class of Nox inhibitors. We therefore produced and began the initial characterization of fulvenes as potential Nox inhibitors, finding that fulvene-5 efficiently inhibited Nox activity in vitro and potently inhibited hemangioma growth in vivo. In conclusion, the present study establishes Nox4 as a critical regulator of hemangioma growth and identifies fulvenes as a potential class of candidate inhibitor to therapeutically interfere with Nox function.

    We have utilized {sup 111}In-labeled heterologous platelets to investigate the mechanism of thrombocytopenia in ten children. From the scintigraphic findings, platelet survival times, and clinical information, thrombocytopenia was ascribed to decreased production or to increased destruction. Two patients were found to have bone marrow production defects. Two patients with hemangiomas were studied. In one, the hemangioma was shown not to be the cause of thrombocytopenia. In the second, the hemangioma was proven the source of platelet destruction, but was much more extensive than clinically evident. In both, surgical manipulation of the hemangioma was avoided. Six additional patients had thrombocytopenia due to accelerated destruction. In four, the spleen was shown responsible. In two, however, the spleen was shown not to be responsible for the low platelet counts, and splenectomy was avoided. Thus, {sup 111}In-platelet scintigraphy and survival studies are valuable in the classification and management of childhood thrombocytopenia. We believe that this study should be performed, when possible, in any child with thrombocytopenia where the mechanism is unclear or the therapeutic intervention involves splenectomy or resection of a hemangioma.

    To determine the accuracy of blood-pool imaging in the diagnosis of hepatic hemangiomas, 39 patients with various focal hepatic lesions were studied. The diagnoses in these patients were made by biopsy, angiography, surgical exploration, or clinical stability for a minimum of 14 months. The diagnoses were: hemangiomas (13 patients), hepatoma (three), metastases (19), abscesses (two), and liver cysts (two). After modified in vivo labeling of red blood cells with 20 mCi (740 MBq) of 99mTc pertechnetate, an initial flow study and early (1-15 min) and delayed (1-2 hr) static images were obtained. Increased blood-pool activity with a discordant flow pattern was seen in 11 of 13 patients with hemangiomas. False-negative scans occurred in two hemangiomas with extensive fibrosis. Two of three hepatomas had increased blood-pool activity associated with increased flow in a pattern identical to the increased blood-pool activity. None of the metastatic, abscess, or cystic lesions had increased blood-pool activity at any time after injection. It is concluded that 99mTc red blood cell imaging can distinguish hemangiomas from other focal liver lesions.

    We describe four patients with intraosseous cavernous hemangiomas of the skull which were localized supraorbitally, parietally (two cases), and occipitally. The diameter ranged from 15 mm to 25 mm. They presented with slowly growing mass, tender to pressure, with spontaneous pain, and with freely mobile skin above the cavernoma sites. Magnetic resonance imaging (hyperintensity on T2 and isointensity with brain on T1) and CT (osteolytic lesion with erosion of the tabula externa) confirmed the plain skull films showing the honeycomb or sunburst appearance pattern. Resections and postoperative course were uneventful. In three of these cases there was coexistence with tumors (meningeoma, malignant lymphoma, and malignant melanoma); none of these constellations has been described before. Generally, cavernous hemangiomas of the skull are rare. There is one extensive review published by Barnes in 1984 regarding a period of 136 years with 123 intraosseous hemangiomas of the skull and 74 of the jaws. Unfortunately, the histological confirmation is not completely clear and some capillary hemangiomas are included. In a review of the literature since 1975, we found 103 histologically proven intraosseous cavernous hemangiomas of the skull (with our four cases included) and 22 of the jaws, which are shown in an overview with respect to their localization. The most frequent site was frontal, followed by temporal. PMID:11954766

  5. PHACE(S) syndrome.

    PHACE(S) syndrome is a neurocutaneous disorder of unknown etiology. The acronym refers to the commonest features of PHACE: posterior fossa malformations, large facial hemangiomas, cerebral arterial anomalies, cardiovascular anomalies, and eye anomalies. When ventral developmental defects such as sternal clefting or supraumbilical raphe occur, the PHACES acronym may be used. The hallmark feature of PHACE is the presence of one or more large facial infantile hemangiomas that occupy at least one facial segment. Infantile hemangiomas differ from the capillary malformation (port wine stain) of Sturge-Weber syndrome, and the arteriovenous malformation of Wyburn-Mason syndrome, distinguishing PHACE syndrome from other neurocutaneous disorders with red birthmarks. The true incidence of PHACE has not yet been established. Girls are more commonly affected than boys. Cerebral vascular anomalies are probably the most common extracutaneous feature. Given that several organ systems are involved, a multidisciplinary approach to disease surveillance and treatment is advised. PMID:26564079

    2002-01-01

    Blue rubber bleb nevus syndrome (BRBNS), an uncommon disorder characterized by cavernous hemangiomas, most often of the skin and gastrointestinal tract, is usually diagnosed during childhood and young adulthood. We made this diagnosis in an octogenarian referred to a geriatric medicine clinic because of concerns about his ability to live independently. Ataxia, dementia, focal neurologic signs, and bluish/purplish vascular nodules on his lips, buccal mucosa, tongue, chest, and neck were noted on physical examination. Magnetic resonance imaging (MRI) revealed an old left parietal infarction, multiple cavernous hemangiomas most densely concentrated in the subcortical structures and cerebellum, and areas of hemosiderin deposition. Skin biopsy findings were consistent with hemangioma. The physical examination, MRI, and skin biopsy made a diagnosis of BRBNS likely. The patient's ataxia, dementia, and other neurologic signs can be explained by previous hemorrhage from the vascular malformations in his brain. Blue rubber bleb nevus syndrome is an uncommon cause of a relatively common geriatric syndrome presentation. PMID:11936246

    Intramuscular hemangiomas are unique vascular tumors which are benign in nature, most commonly occurring in the trunk and extremities. When present in head and neck, they most frequently involve the masseter and trapezius muscles, accounting for less than 1% of all hemangiomas. Most of these lesions present with pain and discomfort and some patients may demonstrate progressive enlargement. Due to their infrequency, deep location, and unfamiliar presentation, these lesions are seldom correctly diagnosed clinically. Our report is a clinically misdiagnosed case of a painful soft tissue mass in the right side masseteric region of a 23-year-old female patient, confirmed as intramuscular hemangioma based on imaging studies and histopathologic examination, treated by surgical excision which had no recurrence after a 3-year followup.

    We were able to detect hemihypertrophy of a fetus in a routine prenatal ultrasound examination. The presence of hemangiomas and varicose veins in the hypertrophied left lower extremity at birth enabled us to diagnose the Klippel-Trenaunay-Weber syndrome. The possibility of a congenital arteriovenous fistula causing the constellation of findings was ruled out by a nuclear flow study and a thorough physical examination. A computerized tomographic scan revealed that the hemangiomas were superficial in the hypertrophied left lower extremity and did not interrupt the deep muscle bundles. PMID:6315966

    Clinical history, physical examination, evolution and imaging findings (Colour Doppler sonography, MRI if available) are of pivotal importance in the diagnostic pathway of an infantile vascular anomaly. Histopathology with specific stains and markers is contributive in difficult cases. Differentiation between vascular tumors (hemangioma) and vascular malformations is now well known and integrated into the ISSVA classification. We report here a 6-months-old boy, who presented with a localized cutaneous and expansive vascular birthmark in the left cheek and developed bleedings at the age of 18 months. Diagnostic features of a hemangioma were not evident, and the final diagnosis of a venous malformation was confirmed by histopathology. PMID:25985453

    A case of pericardial cavernous hemangioma is presented. A 62-year-old man had a chest pain and was referred to our hospital because of an abnormal shadow in the mediastinum. Chest computed tomography showed a hypervascular tumor of 2.0 cm in size at the left side of pulmonary artery. Magnetic resonance imaging findings suggested the mucinous part of the tumor, suggesting liposarcoma, thymoma, and neurinoma etc. At surgery, the tumor was found to be in the pericardial cavity. After pericardotomy, the tumor was resected. The diagnosis of the tumor was cavernous hemangioma. There was no evidence of recurrence 2 years after the operation. PMID:27075295

    Maffucci syndrome is a congenital, non-hereditary mesodermal dysplasia manifested by multiple enchondromas and hemangiomas. It is associated with diverse secondary musculoskeletal deformities, which is exceedingly rare. We report a case of hemangiomas and enchondromas localized in the unilateral limb in a patient with Maffucci syndrome. Treatment consists of orthopedic and surgical intervention to minimize deformities and for cosmetic purpose. Careful surveillance for malignant degeneration of both skeletal and non-skeletal tumors, especially in the brain and abdomen, is essential. PMID:23592908

    A wide variety of space occupying lesions may be encountered in the orbit. CT and MR imaging frequently help confirm the presence of a mass and define its extent. Characteristic imaging features may help distinguish among lesions that have overlapping clinical presentations. This review focuses on some of the common orbital masses. Common vascular lesions that are reviewed include: capillary (infantile) hemangioma, cavernous hemangioma (solitary encapsulated venous-lymphatic malformation), and lymphangioma (venous-lymphatic malformation). Benign tumors that are reviewed include: optic nerve sheath meningioma, schwannoma, and neurofibroma. Malignancies that are reviewed include: lymphoma, metastasis, rhabdomyosarcoma, and optic glioma. Key imaging features that guide radiological diagnosis are discussed and illustrated. PMID:23961022

    The purpose of this study was to apply a novel method of multiscale echo texture analysis for distinguishing benign (hemangiomas) from malignant (hepatocellular carcinomas (HCCs) and metastases) focal liver lesions in B-mode ultrasound images. In this method, regions of interest (ROIs) extracted from within the lesions were decomposed into subimages by wavelet packets. Multiscale texture features that quantify homogeneity of the echogenicity were calculated from these subimages and were combined by an artificial neural network (ANN). A subset of the multiscale features was selected that yielded the highest performance in the classification of lesions measured by the area under the receiver operating characteristic curve (Az). In an analysis of 193 ROIs consisting of 50 hemangiomas, 87 hepatocellular carcinomas and 56 metastases, the multiscale features yielded a high Az value of 0.92 in distinguishing benign from malignant lesions, 0.93 in distinguishing hemangiomas from HCCs and 0.94 in distinguishing hemangiomas from metastases. Our new multiscale texture analysis method can effectively differentiate malignant from benign lesions, and thus has the potential to increase the accuracy of diagnosis of focal liver lesions in ultrasound images.

    This paper focuses on the improvement of the diagnostic accuracy of focal liver lesions by quantifying the key features of cysts, hemangiomas, and malignant lesions on ultrasound images. The focal liver lesions were divided into 29 cysts, 37 hemangiomas, and 33 malignancies. A total of 42 hybrid textural features that composed of 5 first order statistics, 18 gray level co-occurrence matrices, 18 Law's, and echogenicity were extracted. A total of 29 key features that were selected by principal component analysis were used as a set of inputs for a feed-forward neural network. For each lesion, the performance of the diagnosis was evaluated by using the positive predictive value, negative predictive value, sensitivity, specificity, and accuracy. The results of the experiment indicate that the proposed method exhibits great performance, a high diagnosis accuracy of over 96% among all focal liver lesion groups (cyst vs. hemangioma, cyst vs. malignant, and hemangioma vs. malignant) on ultrasound images. The accuracy was slightly increased when echogenicity was included in the optimal feature set. These results indicate that it is possible for the proposed method to be applied clinically.

    Abstract We used intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) to explore the possibility of preoperative diagnosis of soft tissue tumors (STTs). This prospective study enrolled 23 patients. Conventional MRI and IVIM examinations were performed on a 3.0T MR imager. Eight (35%) hemangiomas, 11 (47%) benign soft tissue tumors excluding hemangiomas (BSTTEHs) and 4 soft tissue sarcomas (STSs) were assessed. The mean tumor size was about 1652.36 ± 233.66 mm2. Ten b values (0–800 s/mm2) were used to evaluate diffusion and perfusion characteristics of IVIM. IVIM parameters (ADCstandard, ADCslow, ADCfast, and f) of STTs were measured and evaluated for differentiating hemangiomas, BSTTEHs, and STSs. ADCslow and ADCfast value were different for hemangiomas, BSTTEHs, and STSs separately (P < 0.001, P < 0.001, and P = 0.001). ADCslow, cut-off value smaller than 0.93 × 10–3 mm2/s, was the best parameter to differ STSs (0.689 ± 0.173 × 10−3 mm2/s) from hemangiomas (0.933 ± 0.237 × 10−3 mm2/s) and BSTTEHs (1.156 ± 0.120 × 10−3 mm2/s) (P = 0.001). ADCslow (0.93 × 10−3 mm2/s hemangiomas from BSTTs. There were significant difference among hemangiomas, BSTTEHs, and STSs (P = 0.014, P = 0.036, P < 0.001). The ADCstandard, ADCfast, and f value were different (P < 0.05) for STSs (1.009 ± 0.177 × 10−3 mm2/s, 15.700 ± 1.992 × 10−3 mm2/s, 0.503 ± 0.068), hemangiomas (1.505 ± 0.226 × 10−3 mm2/s, 11.675 ± 0.456 × 10−3 mm2/s, 0.682 ± 0.060), and BSTTEHs (1.555 ± 0.176 × 10−3 mm2/s, 11.727 ± 0.686 × 10−3 mm2/s, 0.675 ± 0.054).

    The enchondromatoses, Ollier's disease and Maffucci syndrome, are non-heritable developmental disorders characterized by multiple enchondromas (Olllier's) in association with hemangiomas (Maffucci). Glial neoplasms are reported in both disorders but a pathogenic mechanism underlying this association has not been identified. We report a case of anaplastic astrocytoma in a 23 year old man with Maffucci syndrome whose tumor carried a substitution mutation of arginine for cysteine at position 132 (R132C) of the isocitrate dehydrogenase 1 (IDH1) protein. This mutation, commonly found in Maffucci-associated enchondromas and hemangiomas, was not detected on routine immunohistochemical (IHC) analysis of the astrocytoma using the R132H mutation-specific antibody, commonly applied in clinical laboratories. The R132C mutation was detected by polymerase chain reaction (PCR) and subsequently confirmed using a SNaPshot assay. Because somatic mosaic IDH mutations are associated with enchondromas and hemangiomas in Maffucci syndrome, we looked for the R132C mutation in a hemangioma, peripheral blood mononuclear cells (PBMNC) and histologically normal brain surrounding the tumor from this patient. The mutation was present in the hemangioma, absent in PBMNC, and present in 2% of alleles in ‘normal’ brain. The low level in surrounding brain tissue is consistent with tumor cell infiltration, not mosaicism, as a S173T p53 mutation in the tumor showed similar results. Using IHC, we further demonstrated that the mutant IDH1 protein in this glioma functions as an oncometabolite. Two repressive histone trimethylation marks were strongly positive in the tumor, supporting a role for 2-hydroxyglutarate in the inhibition of histone demethylation. Together, these data demonstrate that an IDH1 mutation common in enchodromatoses underlies the association of glial tumors reported in both Ollier's disease and Maffucci syndrome.

    Serum ferritin concentration increases in dogs in association with various diseases. In this study, we measured serum ferritin levels in dogs with splenic masses, using a sandwich ELISA assay. Eleven dogs with hemangiosarcoma (HSA), six with hematoma, 1 with hemangioma and 3 with lymphoma were enrolled. All dogs with HSA had serum ferritin concentrations above the normal limit (1,357 ng/ml, mean + 2× standard deviation of normal). Increased serum ferritin concentrations have also been observed in few cases of hematoma, hemangioma and lymphoma. Therefore, hyperferritinemia is not specific for splenic HSA, but may have clinical usefulness as a sensitive test for the disease. Further evaluation of serum ferritin concentrations in dogs with splenic HSA is needed. PMID:23803459

    In this study, a case of a right ventricular myxoma and a case of a right ventricular hemangioma are used to demonstrate the ability of live three-dimensional transesophageal echocardiography (3DTEE) to assess the site of tumor attachment. Because 3DTEE has the ability to visualize desired structures in multiple planes, we defined the attached portion of the tumors and measured the en face view dimensions. In addition, the improved ability of 3DTEE to evaluate tissue characteristics allowed differentiation of the heterogeneous myxoma and highly vascular hemangioma. On the contrary, because two-dimensional (2D) TEE only allows structures to be viewed in a 2D plane, the attachment site can be located but complete delineation and measurement of area is not possible. As surgical options become less invasive, accurate attachment site location and size will become more important to ensure complete excision. PMID:21929586

    Propranolol and timolol are nonselective ß-adrenergic antagonists that induce peripheral vasoconstriction and affect angiogenic cytokines. Oral and topical ß-blocker therapy has become the de facto first-line treatment for complicated infantile hemangiomas because of its superior efficacy and tolerability. Pyogenic granulomas or lobular capillary hemangiomas are common acquired vascular tumors accounting for 0.5% of all skin nodules in children. Although they are benign vascular proliferations, treatment is often sought because of recurrent episodes of bleeding and for cosmetic considerations. Numerous treatment options are available, but recurrence rates are high. Noninvasive methods of treatment are being sought, particularly for young children. Herein we report a series of seven cases of cutaneous and mucosal pyogenic granulomas treated successfully using oral or topical ß-blockers. PMID:24138457

    Pyogenic granuloma, also named lobular capillary hemangioma, is a common proliferative vascular lesion known as a benign condition despite its rapid growth. It may appear in any cutaneous or mucosal surface but is usually restricted to the oral cavity. It is characterized by a friable mulberry-like lesion that can be sessile or pedunculated. Bleeding is usually its first clinical manifestation. Locations on respiratory, digestive and genital tracts are uncommon and sporadic. We describe the occurrence of an intravaginal pyogenic granuloma in a peripubertal girl with recurrent vaginal bleeding. This is the first reported case of a genital tract lobular capillary hemangioma in pediatric age to our knowledge. Therefore, we suggest this entity in the differential diagnosis of an unclear peripubertal vaginal bleeding. PMID:25324441

    In this study, we propose a computer-aided classification scheme of liver tumor in 3D ultrasound by using a combination of deformable model segmentation and support vector machine. For segmentation of tumors in 3D ultrasound images, a novel segmentation model was used which combined edge, region, and contour smoothness energies. Then four features were extracted from the segmented tumor including tumor edge, roundness, contrast, and internal texture. We used a support vector machine for the classification of features. The performance of the developed method was evaluated with a dataset of 79 cases including 20 cysts, 20 hemangiomas, and 39 hepatocellular carcinomas, as determined by the radiologist's visual scoring. Evaluation of the results showed that our proposed method produced tumor boundaries that were equal to or better than acceptable in 89.8% of cases, and achieved 93.7% accuracy in classification of cyst and hemangioma.

    Four-hundred-eighty Mongolian gerbils, Meriones unguiculatus [Uclp:(MON)], most of which were experimentally infected with filarial worms, were examined for spontaneous lesions. Previously unrecognized lesions included cutaneous squamous cell carcinoma, duodenal adenocarcinoma, malignant blue nevus, hepatic choleangiocarcinoma, malignant hemangiopericytoma of the uterus, ovarian teratoma, chronic interstitial nephritis, renal cortical retention cysts, splenic hemangiomas, and various histologic abnormalities of the lung. Previously reported lesions also seen in the present study were a malignant melanoma, adrenal cortical adenoma or carcinoma, uterine leiomyoma, sebaceous gland adenoma, hepatic lymphangioma, and renal hemangioma. Hymenolepis diminuta (Cestoda) and Tyrophagus castellani (Acarina) were accidentally recovered from experimental animals. Tritichomonas caviae and a species of Entamoeba were the most common intestinal protozoa.

    Fluid-fluid levels in bone tumors have been described in aneurysmal bone cysts and other cystic tumors of bones and soft tissue tumors. We experienced three bone tumors (simple bone cyst, bone metastasis, and osteosarcoma) and three soft tissue tumors (fibrosarcoma, two cases of cavernous hemangioma) that showed fluid-fluid levels on MR, and investigated their cause. Causes included blood in the cystic spaces, hemorrhage in the tumor, the telangiectatic component of the osteosarcoma, and the cavernous component of the hemangioma. No specific diagnosis could be made based on the finding of fluid-fluid levels. We conclude that fluid-fluid levels on MR are rather nonspecific findings in bone and soft tissue tumors and that the diagnosis should be made on the basis of other radiological and clinical findings.

    The incidence of mesenteric lymph node vascular tumors can vary in rats, and appropriate assessment of potential risk of tumorigenicity is needed when the incidence is higher in treated groups than in a control group. In a 2-year rat carcinogenicity study of luseogliflozin, a selective sodium-dependent glucose co-transporter 2 inhibitor for the treatment of type 2 diabetes mellitus, there was a slight but statistically significant increase in the total number of hemangiomas and hemangiosarcomas in the mesenteric lymph nodes in males at a high-dose. As part of the risk assessment for luseogliflozin, its effect on the vascular proliferation potential in the mesenteric lymph nodes was examined in a rat carcinogenicity study by performing an image analysis using specimens with double immunohistochemical staining for PCNA and CD34 in control and high-dose males. In addition, immunohistochemical staining for VEGF was performed to detect enhanced angiogenesis. In the high-dose males that did not have a hemangioma/hemangiosarcoma, neither an increased number of PCNA/CD34-positive cells nor changes in the expression pattern of VEGF was observed. On the other hand, in the high-dose males that had a hemangioma/hemangiosarcoma, the number of PCNA-positive cells was increased in the tumor areas, and the number in the hemangioma/hemangiosarcoma was approximately one-half of that in the hemangiosarcoma in the control male. In conclusion, no potential change leading to vascular proliferation/tumors was detected in the mesenteric lymph nodes of high-dose males receiving luseogliflozin. PMID:27182112

    The authors reviewed their experience with computerized tomography (CT) of the abdomen in 212 patients with histologically documented liver neoplasms seen during a 30-month period. The CT findings in cavernous hemangioma and focal nodular hyperplasia were specific, and permitted accurate diagnosis of this lesion before biopsy. The CT appearance of all other lesions was variable. CT is useful in providing an accurate evaluation of the intrahepatic and extrahepatic extent of the neoplasm.

    Sturge-Weber syndrome has been included in the group of phakomatoses that is characterized by hamartomas involving the brain, skin, and eyes. The characteristic facial port-wine stain, involving the first branch of the trigeminal nerve and the embryonic vasculature distribution in this area, leads to several ocular complications of the anterior segment and can involve the eyelids and conjunctiva. The posterior segment of the eyes is also affected with diffuse choroidal hemangiomas. However, the most frequent ocular comorbidity is glaucoma with a prevalence rate ranging from 30%-70%. Glaucoma is related to anterior chamber malformations, high episcleral venous pressure (EVP), and changes in ocular hemodynamics. Glaucoma can be diagnosed at birth, but the disease can also develop during childhood and in adults. The management of glaucoma in Sturge-Weber syndrome patients is particularly challenging because of early onset, frequently associated severe visual field impairment at the time of diagnosis, and unresponsiveness to standard treatment. Several surgical approaches have been proposed, but long-term prognosis for both intraocular pressure control and visual function remains unsatisfactory in these patients. Choroidal hemangiomas may also lead to visual impairment thorough exudative retinal detachment and macular edema. Treatment of exudative hemangioma complications is aimed at destructing the tumor or decreasing tumor leakage. PMID:27257371

    Surgical intervention consisting of lateral orbitotomy, the indication of which is extremely wide for orbital tumor surgery, has been applied in cases of large, retrobulbar cavernous hemangioma. However, no method exists involving displacement of the tumor from the crowded orbital contents, with the exception of tumor traction toward the outer side. The impact of traction force on the fragile hemangioma is extremely traumatic and dangerous. The authors examined how a tumor might be "displaced" in the absence of traction force effect, into an appropriate cavity neighboring the orbit. The maxillary sinus may afford the most suitable space to shift the laterally situated orbital tumor. Thus, the osteotomy level was extended to the lateral half of the inferior orbital floor and orbital rim in order to displace the tumor through an "escape window" of sufficient size between the orbit and maxilla. This report describes the treatment of two cases with long histories of progressive proptosis associated with retrobulbar large cavernous hemangiomas. This novel procedure resulted in a successful outcome. The current approach and management, which involves displacement of the tumor into the maxillary sinus through the orbital floor escape window, is a novel procedure for orbital tumor surgery.

    Infantile hemangioendothelioma is the most common symptomatic vascular liver tumor of infancy. It is considered a benign tumor; however, aggressive behavior is occasionally seen microscopically, and rarely distant metastases have been reported. The exact incidence of infantile hemangioendothelioma is difficult to determine because often it has been either misdiagnosed or mislabeled as cavernous hemangioma in the literature. Cavernous hemangioma is the most common primary liver tumor in older age groups but is rarely found in infants as a clinically significant tumor. Levick and Rubie were the first to recognize an association between hemangioendothelioma of the liver and congestive heart failure, and there were subsequent reports substantiating this association. However, it is our impression and the finding of others that congestive heart failure is distinctly less common than abdominal mass or hepatomegaly as the presenting sign in infantile hemangioendothelioma. Congestive heart failure is rarely a feature of cavernous hemangioma. Because of the errors in terminology and questions regarding clinical presentation, a radiologic-pathologic-clinical correlation study of infantile hemangioendothelioma and review of the literature was undertaken.

    PHACE syndrome is a neurocutaneous disorder characterized by large cervicofacial infantile hemangiomas and associated anomalies: posterior fossa brain malformation, hemangioma, arterial cerebrovascular anomalies, coarctation of the aorta and cardiac defects, and eye/endocrine abnormalities of the brain. When ventral developmental defects (sternal clefting or supraumbilical raphe) are present the condition is termed PHACE. In this report, we describe three PHACE cases that presented unique features (affecting one of the organ systems described for this syndrome) that have not been described previously. In the first case, a definitive PHACE association, the patient presented with an ipsilateral mesenteric lymphatic malformation, at the age of 14 years. In the second case, an anomaly of the posterior segment of the eye, not mentioned before in PHACE literature, a retinoblastoma, has been described. Specific chemotherapy avoided enucleation. And, in the third case, the child presented with an unusual midline frontal bone cleft, corresponding to Tessier 14 cleft. Two patients' hemangiomas responded well to propranolol therapy. The first one was followed and treated in the pre-propranolol era and had a moderate response to corticoids and interferon. PMID:26221546

    Abstract To analyze the clinical characteristics and treatment outcomes of vascular anomalies, and determine which therapy is safe and effective. The data of vascular anomalies pediatric patients who arrived at Beijing children's Hospital from January 2001 to December 2014 were analyzed retrospectively, including the influence of gender, age, clinical manifestation, diagnosis, treatment options, and outcomes. As to infantile hemangiomas, the outcomes of different treatments and their adverse reactions were compared. As to spider angioma and cutaneous capillary malformation, the treatment effect of 595 nm pulsed dye laser (PDL) is analyzed. A total number of 6459 cases of vascular anomalies were reclassified according to the 2014 ISSVA classification system. Among them, the gender ratio is 1:1.69, head-and-neck involved is 53.3%, the onset age within the first month is 72.4%, the age of initial encounter that younger than 6 months is 60.1%. The most common anomalies were infantile hemangiomas (42.6%), congenital hemangiomas (14.1%), and capillary malformations (29.9%). In treating infantile hemangiomas, laser shows the lowest adverse reactions rate significantly. Propranolol shows a higher improvement rate than laser, glucocorticoids, glucocorticoids plus laser, and shows no significant difference with propranolol plus laser both in improvement rate and adverse reactions rate. The total improvement rate of 595 nm PDL is 89.8% in treating spider angioma and 46.7% in treating cutaneous capillary malformation. The improvement rate and excellent rate of laser in treating cutaneous capillary malformation are growing synchronously by increasing the treatment times, and shows no significant difference among different parts of lesion that located in a body. Vascular anomalies possess a female predominance, and are mostly occurred in faces. Definite diagnosis is very important before treatment. In treating infantile hemangioma, propranolol is recommended as the first

    Background Kasabach-Merritt syndrome (KMS) is characterized by giant hemangiomas and severe thrombocytopenia, which may result in life-threatening multi-organ hemorrhage. This study evaluated the clinical characteristics, treatments, and outcomes in neonates with KMS, in order to find out the optimal therapy. Methods The clinical data of 17 patients treated for KMS in the Department of Neonates, Guangzhou Women and Children’s Medical Center, Guangzhou Medical University, China from January 2007 to January 2012 were retrospectively analyzed. Results The patients were 13 males and 4 females, aged 17 hours to 28 days at admission. Four patients had visceral hemangiomas and 13 had cutaneous hemangiomas. All had thrombocytopenia and coagulation disorders. Intravenous steroid therapy was initially effective in 6 patients (of which 3 relapsed) and ineffective in 11. The 11 patients with a poor response to steroids and the 3 who relapsed underwent arterial embolization therapy, which was effective in 9 patients (of which 1 relapsed), ineffective in 4, and discontinued before completion in 1. Subsequently, four patients in whom arterial embolization therapy was ineffective and one with relapse were treated with vincristine. This was effective in four patients, and the other died of disseminated intravascular coagulation. Steroid therapy was effective in 35.3% of patients, but the relapse rate was 50%. Arterial embolization was effective in 64.3% of patients and vincristine was effective in 80%. Conclusions In patients with neonatal KMS, steroid therapy has a low rate of effectiveness and high rate of relapse. Arterial embolization has a good rate of effectiveness. Combined steroid and embolization therapy should be considered for first-line treatment of neonatal KMS. If this approach is ineffective, vincristine may be useful. PMID:24920221

    Angiosarcoma (AS) is a rare malignant vascular tumor, whereas epithelioid hemangioendothelioma (EHE) is a vascular tumor of low-grade malignancy. CD30 is a member of the tumor necrosis factor receptor superfamily, member 8 (TNFRSF8). Although the expression of CD30 is most commonly associated with lymphoid malignancies or germ cell tumors, occasional ASs have been reported as CD30 positive. However, there are limited data to evaluate its role definitively in malignant vascular tumors. In this study, we evaluated 91 ASs, 30 EHEs from various sites, and 25 Kaposi sarcomas. Overall, CD30 was expressed in 31/91 cases (34%) of AS, in 7/30 cases (30%) of EHE, but in none of the Kaposi sarcomas. CD30 was expressed in a membranous staining pattern and positivity in tumor cells varied from focal to diffuse. The positive ASs included vasoformative more differentiated tumors and also solid, undifferentiated, lymphoma-like examples, one of which was classified as lymphoma before the era of immunohistochemistry. The CD30 expression was seen in >50% of tumor cells in a majority of ASs but only in 7% of EHEs. None of the 55 ASs studied were immunohistochemically positive for TIA-1 or Granzyme B, antigens used as more specific markers for anaplastic large-cell lymphoma. Compared with AS, normal vascular endothelia of capillaries and muscular vessels showed variable positivity. Among hemangiomas, cavernous and spindle cell hemangiomas showed most frequent endothelial CD30 positivity, whereas in most other hemangiomas, CD30 positivity was scant. In conclusion, CD30 expression occurs in a significant subset of ASs and EHEs and needs to be included in the differential diagnosis with other CD30-positive malignancies to avoid a diagnostic pitfall. It remains to be determined whether patients with strongly CD30-positive ASs could be candidates for targeted therapy using the recently introduced CD30 antibody drug conjugates. PMID:24805132

    AIM To identify the association of the T cell receptor (TCR) signaling with the development of benign lymphoepithelial lesions (BLEL) of the lacrimal gland. METHODS We collected affected lacrimal gland tissues from 9 patients who underwent dacryoadenectomy in the Capital Medical University Beijing Tongren Hospital Eye Center between August 2010 and March 2013 and were confirmed to have lacrimal gland BLEL by histopathological analysis. Tumor tissues from 9 patients with orbital cavernous hemangioma were also collected and used as control. Whole genome gene expression microarray was used to compare gene expression profiles of affected lacrimal gland tissues from patients with lacrimal gland BLEL to those from of orbital cavernous hemangiomas. Differential expression of TCR pathway genes between these tissues was confirmed by polymerase chain reaction (PCR) and immunohistochemistry. RESULTS Microarray analysis showed that in lacrimal glands with BLEL, 32 signaling pathways were enriched in the upregulated genes, while 25 signaling pathways were enriched in the downregulated genes. In-depth analysis of the microarray data showed that the expression of 27 genes of the TCR signaling pathway increased significantly. To verify the differential expression of three of these genes, CD3, CD4, and interleukin (IL)-10, reverse transcription-PCR (RT-PCR) and immunohistochemistry assays were performed. RT-PCR analysis showed that CD3 and CD4 were expressed in the lacrimal glands with BLEL, but IL-10 was not expressed. Immunohistochemistry confirmed that CD3 and CD4 proteins were also present, but IL-10 protein was not. CD3, CD4, or IL-10 expression was not found in the orbital cavernous hemangiomas with either RT-PCR or immunohistochemistry. CONCLUSION TCR signaling pathway might be involved in the pathogenesis of lacrimal gland BLEL. PMID:26309862

    Focal liver lesions (FLL) have been a common reason for consultation faced by gastroenterologists and hepatologists. The increasing and widespread use of imaging studies has led to an increase in detection of incidental FLL. It is important to consider not only malignant liver lesions, but also benign solid and cystic liver lesions such as hemangioma, focal nodular hyperplasia, hepatocellular adenoma, and hepatic cysts, in the differential diagnosis. In this ACG practice guideline, the authors provide an evidence-based approach to the diagnosis and management of FLL. PMID:25135008

    Vascular lesions of the scrotum are uncommon; the most common among them are varicocele lesions. The other vascular lesions that may involve the scrotum are hemangioma, lymphangioma, and arteriovenous malformations, which are exceedingly rare. The imaging modalities useful in the diagnosis and management of scrotal vascular lesions are grayscale sonography, color Doppler sonography, magnetic resonance imaging, magnetic resonance angiography, and digital subtraction angiography. We present two cases of scrotal vascular lesions involving the extratesticular scrotal soft tissues. Patients presented with bleeding and were treated by radiological interventional technique. We emphasize the importance of superselective catheterization and distal embolization.

Lesions studied included abscesses, cavernous hemangioma/hemangioendothelioma, adenoma of glycogen storage disease, choledochal cysts, focal nodular hyperplasia, cystic hepatoblastoma, and hamartoma. An intergrated imaging protocol involving ultrasound, computed tomography, and scintigraphy proved to be more helpful than any one modality in establishing the benign or malignant nature of a hepatic neoplasm and the type of tumor, which is of particular importance when surgical exploration and/or biopsy is contraindicated.

    A prototype low-cost RGB imaging system consisting of a commercial RGB CMOS sensor, RGB light-emitting diode ring light illuminator, and a set of polarizers was designed and tested for mapping the skin erythema index, in order to monitor skin recovery after phototherapy of vascular lesions, such as hemangiomas and telangiectasias. The contrast of erythema index (CEI) was proposed as a parameter for quantitative characterization of vascular lesions. Skin recovery was characterized as a decrease of the CEI value relative to the value before the treatment. This approach was clinically validated by examining 31 vascular lesions before and after phototherapy. PMID:24362928

    Radiofrequency ablation (RFA) is a well-established treatment modality in the treatment of early hepatocellular carcinoma (HCC) [1]. Safe trajectory of the RFA probe is crucial in decreasing collateral tissue damage and unwarranted probe transgression. As a percutaneous technique, however, the trajectory of the needle is sometimes constrained by the available imaging plane. The presence of a hemangioma beside an HCC is uncommon but poses the question of safety related to probe transgression. We hereby describe a case of transhemangioma ablation of a dome HCC.

    Nasal encephalocele are rare congenital anomalies; these benign masses may be confused with nasal dermoids, hemangiomas, nasal gliomas and anterior skull base masses. These lesions have concomitant defects in the anterior cranial fossa thus this potential communication can cause recurrent episodes of meningitis and/or difficulty in breathing and cosmetic anomalies. We bring a case of a 6-year-old child who presented to the clinic with multiple episodes of meningitis which was associated with nasal discharge. The imaging studies and nasal fluid analysis confirmed it as cerebrospinal fluid; subsequently imaging findings concluded it as frontonasal encephalocele which was later resected and patient showed improvement.

Current treatment modalities to reduce these lesions include topical and/or intralesional steroids, laser therapy, surgical resection, and endovascular therapy. However, each method has limitations owing to recurrence, comorbidities, toxicity, or lesion location. Photodynamic therapy, antiangiogenic therapy, and evolving methods of sclerotherapy are promising areas of development that may mitigate limitations of current treatments and offer exciting options for patients and their physicians.

    Sturge-Weber syndrome (SWS) is a congenital, sporadically occurring, neurocutaneous syndrome that presents classically with port-wine stain, leptomeningeal angiomas, and glaucoma. The systemic implications of SWS are vast and involve not only ophthalmic manifestations but also dermatologic, neurologic, and oral manifestations. Neuroimaging, in particular, plays an important role in the diagnosis and management of this disease. Recent discoveries have been made regarding the genetic pathogenesis of SWS. In addition, recent advances have been made in the management of the 2 most common ophthalmic manifestations of SWS: diffuse choroidal hemangioma and glaucoma. Despite these new contributions to the field, many challenges still remain. The management of diffuse choroidal hemangioma is wide ranging and includes photodynamic therapy, brachytherapy, radiotherapy, and antivascular endothelial growth factor injections, but all have had limited or varied success. Although there have been recent advances in knowledge and technique, the management of glaucoma is extremely complex, given the high surgical risks for complications and a poor response rate to medical therapy. Further studies are critical to maximize our knowledge of this difficult disease. PMID:26107979

    We report a case of an intraventricular angiomatous meningioma arising in a 3-year-old boy diagnosed with Sturge-Weber syndrome (SWS) who presented with intractable epilepsy and right-sided hemiparesis. He underwent surgical resection of the epileptogenic focus. Histologic sections showed the typical findings of SWS accompanied by adjacent mild focal cortical dysplasia (International League Against Epilepsy Type Ib pattern; Palmini et al. Type IA). A small intraventricular mass, which was incidentally noted on imaging studies, was also excised. The mass showed a prominent venous vasculature with intermixed meningothelial cells, consistent with an angiomatous meningioma World Health Organization Grade I. SWS is a rare, sporadically occurring disorder marked by a port wine stain (hemangioma of the skin) arising in the distribution of the trigeminal nerve accompanied by an angiomatous proliferation in the leptomeninges. The underlying cortex often shows prominent dystrophic mineralization and gliosis. Patients often present with seizures and may require surgical resection when seizures prove to be pharmacoresistant. Meningiomas in SWS are a rare occurrence (only one known previously reported case) and angiomatous meningioma in SWS has never been described. The literature is briefly reviewed and the pathogenesis of hemangiomas in SWS and its implication in angiomatous meningioma is discussed. PMID:25766367

    This report describes the histopathology of two hundred and fifty-three mesenchymal tumors of the urinary bladder in cattle grazing on lands rich in bracken fern. Approximately 80% were hemangiomas and angiosarcomas. Hemangioma (capillary, cavernous, and large vessels) was the most frequent mesenchymal tumor and was more common than angiosarcoma. Although the appearance of endothelial cells can vary remarkably, epithelioid angiosarcomas, often containing multinucleated cells, were the most frequent malignant vascular tumors. Hemangiopericytoma and tumors of muscle and soft connective tissue origin, alone and/or in association with tumor-like lesions, were less frequently seen. Furthermore, forty-five cases of intravascular papillary endothelial hyperplasia (IPEH), a lesion not previously reported in the urinary bladder of cattle, were also described. Bovine papillomavirus type-2 DNA was amplified in tumor samples. Forty vascular tumors were investigated by dual-labeling immunofluorescence, and, for the first time, a coexpression of E5 and platelet-derived growth factor β receptor (PDGFβR) was shown to occur. The results show that the BPV-2 E5 oncoprotein binds to the activated form of the PDGFβ receptor thus playing an important role in mesenchymal as well as epithelial carcinogenesis of the urinary bladder. Furthermore, these findings demonstrate that BPV-2 infects both epithelial and mesenchymal cells. PMID:23862156

    Imaging of hepatocellular carcinoma (HCC) is complicated because the tumor has a varied radiologic appearance and frequently coexists with cirrhotic regenerative and dysplastic nodules. In cirrhotic patients, any dominant solid nodule that is not clearly a hemangioma should be considered a HCC until proven otherwise, especially if the lesion is hypervascular, of high T2 signal intensity, or demonstrates venous invasion. Biopsy of HCC in cirrhosis is risky and surveillance is often preferable. The doubling time of HCC is 1 to 12 months, and a nodule that is stable over 4 months is very unlikely to be a HCC. However, stable nodules cannot be dismissed, since livers containing dysplastic nodules are at high risk to develop HCC. In noncirrhotic patients, any solid mass that is not clearly a hemangioma or focal nodular hyperplasia is potentially a HCC, and biopsy may be required. Venous invasion by tumor should be distinguished from bland thrombus. Imaging detection of nodal metastases is limited by the frequent finding of benign reactive lymphadenopathy in cirrhosis. Resection is the preferred treatment for HCC, but is contraindicated in the presence of tumors in both lobes, major venous invasion, invasion of adjacent organs other than the gallbladder, tumor rupture, nodal metastases, or distant metastases.

    Pyogenic granuloma is one of the diseases sometimes seen in otorhinolaryngology clinics. The clinical features of this disease are understood to be that the lesion is located in the oral cavity in the majority of cases that its causative agent is usually discovered and that it most likely grows as a malignant tumor. However, the entity of pathological diagnosis has not been established. Thirty-one cases of oral pyogenic granuloma, including 16 males and 15 females, are reported in this paper. The granuloma was located most frequently at the tongue, followed, in order, by the gingiva, buccal mucosa, hard palate, lip and oral floor. The period between the patient's first visit to our clinic and the onset of his/her complaint was variable. It was relatively shorter in those cases with the lesion at the gingiva or tongue as compared to other locations. The size of the lesion was smaller than 10 x 10 mm. We classified the pathological features into three patterns; granuloma type, hemangioma type, and intermediate type. Many cases of lesions located at the back of the tongue, buccal mucosa, or hard palate were of the hemangioma type, while many cases of lesions located at the top of the tongue, gingiva, or oral floor were of the granuloma type. We have the impression that pyogenic granuloma could be one of the purulent changes associated with benign oral tumors. PMID:1779270

    To present our recent experience with intralesional bleomycin (IBI) in nonmelanoma extraocular tumors, and present previous experience on periocular capillary hemangiomas and orbital lymphangiomas in a tertiary referral hospital. This was a retrospective descriptive study of patients with eyelid and extraocular malignancies where conventional therapies failed, or surgery was contraindicated or refused and were offered IBI as an alternate therapy. All patients were recruited from the Oculoplastics Clinic at Tygerberg Academic Hospital, Cape Town, South Africa. A solution containing 1 international unit of bleomycin per milliliter saline was injected intralesionally together with 2% lignocaine in a ratio of 4:1. The injected volume was calculated to be equivalent to the estimated volume of the lesion. A multipuncture technique with a 29-gauge needle was used. Patients requiring retreatment were injected every 4–8 weeks until satisfactory clinical endpoints were achieved. Our previous experience with IBI in extensive capillary hemangiomas and orbital lymphangiomas is reviewed. Cases are presented to illustrate that IBI induced significant regression and reduction in tumor size and marked clinical improvement of the eyelid and orbital basal cell carcinomas, Kaposi sarcoma, and mycosis fungoides. The improvements obviated the need for further surgical intervention in most cases. Based on clinical experience we propose that IBI should be considered a treatment modality in select cases of the malignant eyelid and ophthalmic vascular tumors where the conventional standard of care is not possible. IBI is a reasonable alternative or adjunct to consider in such cases. PMID:26692709

    Infantile hepatic hemangioendothelioma (IHH) is rare which can regress spontaneously. Arteriovenous shunts within hemangiomas, however, may result in pulmonary artery hypertension (PAH) and congestive heart failure (CHF).The authors report 2 young infants suffering from multifocal IHH associated with CHF were both treated with glucocorticoid and transcatheter arterial embolization (TAE), but had different outcomes. The PAH decreased immediately and the symptoms of CHF were alleviated after TAE for both of them. For the Tibetan infant, the development was normal with tumor regression by follow-up. For the Han ethnic neonate, PAH increased again in the seventh day with progressive cardiovascular insufficiency. Ultrasound showed a persisting perfusion caused by collateralization around occluded main feeders. Furthermore, a pulmonary infection occurred and ventilation was performed. As a result, the infant died from multiorgan failure caused by CHF and infection.TAE is a treatment of reducing shunting for hemangiomas. Fistula recanalization in multifocal IHH, however, might be an important risk factor affecting the outcome of TAE. TAE should be further evaluated with special attention to anatomy of feeding and draining vessels, and cardiopulmonary conditions. In addition, the patients were susceptible to secondary pulmonary infection because of lung congestion. As well, the infant from the high altitude area showed better adaptability to hypoxia.

    This study was devoted to tumor differentiation in liver MR T1-weighted imaging with superparamagnetic iron oxide (SPIO). Twenty-one patients with 40 liver lesions were studied at 1.5 T. Before and at least 45 minutes after SPIO administration, turbo-field-echo (TFE) T1-weighted, TFE T1 x T2*-weighted (MXT), and fat-suppressed turbo-spin-echo T2-weighted images were acquired. A quantitative analysis was performed blindly. On TFE T1-weighted images, the signal enhancement was -33% +/- 12 for the liver, -24% +/- 2 for adenomas and focal nodular hyperplasia, +60% +/- 33 for the hemangiomas; metastases and cyst enhancement were not significant. After SPIO on TFE T1-weighted images, the hemangioma-to-liver signal ratio (149% +/- 18) was definitely higher than the mean metastasis-to-liver signal ratio (90% +/- 16). This T1-related differentiation ability lacked dramatically on TFE MXT images and, in one case, was reduced on post-SPIO TFE T1-weighted images by a long imaging delay after SPIO administration (2 hours).

    Background. Pyogenic granuloma is a reactive tumor-like lesion commonly affecting the oral cavity. These lesions usually appear as localized solitary nodule with a sessile or pedunculated base and colour varying from red, purplish, or pink, depending on the vascularity of the lesion. Pyogenic granuloma shows predilection for gingiva and is usually slow growing, but at times it shows rapid growth. The natural course of this lesion can be categorized into three distinct phases, namely, (i) cellular phase, (ii) capillary phase/vascular phase, and (iii) involutionary phase. Histopathologically, pyogenic granuloma is classified into lobular capillary hemangioma (LCH) and non-lobular capillary hemangioma (non-LCH). Case Presentation. In this series, four cases (varied age groups and both genders) of pyogenic granuloma showing varying histopathological presentation in relation to its clinical course have been described. The lesion in its early phase reveals diffuse endothelial cells, with few budding into capillaries. Among the capillary phase, the LCH type shows numerous blood vessels organized into lobular aggregates whereas the non-LCH type does not show any such organization and resembles granulation tissue. The involutionary phase shows healing of the lesion and is characterized by extensive fibrosis in the connective tissue. Conclusion. In conclusion, knowledge of the various histopathological presentation of this lesion is necessary for proper identification. PMID:27382492

    Vascular tumors are among the most common neoplasms in infants and children; 5%-10% of newborns present with or develop lesions within the first 3 months of life. Most are benign infantile hemangiomas that typically regress by 5 years of age; other vascular tumors include congenital tufted angiomas (TAs), kaposiform hemangioendotheliomas (KHEs), and childhood lobular capillary hemangiomas (LCHs). Some of these lesions can become locally invasive and unresponsive to pharmacologic intervention, leading to significant complications. Recent investigation has revealed that activating mutations in HRAS, KRAS, NRAS, GNAQ, and GNA11 can cause certain types of rare childhood vascular tumors, and we have now identified causal recurrent somatic activating mutations in GNA14 by whole-exome and targeted sequencing. We found somatic activating GNA14 c.614A>T (p.Gln205Leu) mutations in one KHE, one TA, and one LCH and a GNA11 c.547C>T (p.Arg183Cys) mutation in two LCH lesions. We examined mutation pathobiology via expression of mutant GNA14 or GNA11 in primary human endothelial cells and melanocytes. GNA14 and GNA11 mutations induced changes in cellular morphology and rendered cells growth-factor independent by upregulating the MAPK pathway. Our findings identify GNA14 mutations as a cause of childhood vascular tumors, offer insight into mechanisms of oncogenic transformation by mutations affecting Gaq family members, and identify potential targets for therapeutic intervention.

    Evaluation of a liver nodule detected with ultrasound includes the recovery of a detailed medical history, a physical exam, appropriate contrast imaging examinations and, in selected cases, histopathology. In this setting, identification of liver disease accompanying a liver nodule helps distinction between benign nodules and metastatic malignant nodules from primary liver cancer, as recommended by scientific liver societies. Diagnostic algorithms for a liver nodule in patients with liver disease involve contrast CT scan, magnetic resonance imaging or contrast enhanced ultrasounds to show the typical neoplastic pattern of early arterial hyperenhancement wash-in followed by hypoenhancement in the late portal phase wash out. The flow charts developed by western societies utilize the discriminant criterion of tumor size i.e. the radiological diagnosis being endorsed in a nodule equal or greater than 1 cm whereas eastern societies rely on the recognition of a typical vascular pattern of the node, independently of size. Differential diagnosis should be obtained to differentiate liver related nodules like regenerative macronodules (more than 20% of the cases) and the less frequent intrahepatic cholangiocarcinoma (~2% of the cases) from liver disease unrelated nodules like hemangioma (~4%), neuroendocrine metastatic nodules (~1%) and focal nodular hyperplasia. In patients without liver disease, the most common liver nodules in the liver are hemangioma (~1.5%), focal nodular hyperplasia (0.03%) and hepatocellular adenoma (up to 0.004% in long term users of oral contraceptives). Optimization of management of patients with a liver nodule requires establishment of a multidisciplinary clinic. PMID:25864209

    The acronym PHACE has been used to denote a constellation of abnormalities: posterior fossa anomalies, facial hemangiomas, arterial anomalies, cardiac anomalies, and eye abnormalities. Approximately 30% of patients with large facial hemangiomas have PHACE syndrome, with the vast majority having intracranial arteriopathy. Few reports characterize neurological deterioration from this intracranial arteriopathy, and even fewer report successful treatment thereof. The authors report on a case of a child with PHACE syndrome who presented with an ischemic stroke from a progressive intracranial arteriopathy and describe her successful treatment with bilateral pial synangiosis. An 8-month old girl diagnosed with PHACE syndrome was found to have bilateral internal carotid artery stenosis. Although initially asymptomatic, a few months after diagnosis she suffered a right frontal and parietal stroke. MRI and cerebral angiography investigations demonstrated progressive intracranial arterial stenosis and occlusion. The patient then underwent indirect cerebral revascularization surgery. At 2-year follow-up, she exhibited clinical improvement with persistent speech and motor developmental delay. Follow-up MRI and cerebral angiography showed no new ischemic events and robust extensive vascular collateralization from surgery. PHACE syndrome is an uncommon disease, and affected patients often have cerebral arteriopathy. Although the underlying natural history of cerebral arteriopathy in PHACE remains unclear, cerebral revascularization may represent a potential therapy for symptomatic patients. PMID:26405843

    Ranging behind hemangiomas, focal nodular hyperplasias (FNH) are the second most common benign solid liver lesions. Women between the age of 20 and 50 years are predominantly affected. In rare cases FNH may occur in children. Etiologically, an arteriovenous vascular malformation of the liver is discussed, which causes pseudotumorous growth of the surrounding liver parenchyma. Morphological features such as the presence of a radial vascular architecture and feeding arteries within a central scar are characteristic for the presence of FNH. Imaging techniques which enable the depiction of the arterial blood supply with a characteristic centrifugal filling pattern, the contrast enhancement in the early arterial phase, the absence of calcifications and of a tumour capsule and the typical enhancement of the central scar, are of particular importance. Knowledge of these features is important in order to differentiate FNH from other hypervascular focal liver lesions with tendency of scar formation, such as hepatic adenomas, giant hemangiomas, hepatocellular and fibrolamellar carcinomas, and metastases. Diagnosis and differential diagnosis of FNH will be enabled by a combined modality approach consisting of (Doppler) sonography and triphasic CT. To confirm the diagnosis of FNH, dynamic MRI is advisable. Because of the invasiveness of angiography as well as the limited sensitivity and spatial resolution of the various scintigraphic methods, these modalities no longer play a role in the diagnostic work-up of FNH. Lesions lacking typical features diagnostic for FNH remain subjects for biopsy and histological examination. PMID:11079084

    Therapeutic targeting of the beta-adrenergic receptors has recently shown remarkable efficacy in the treatment of benign vascular tumors such as infantile hemangiomas. As infantile hemangiomas are reported to express high levels of beta adrenergic receptors, we examined the expression of these receptors on more aggressive vascular tumors such as hemangioendotheliomas and angiosarcomas, revealing beta 1, 2, and 3 receptors were indeed present and therefore aggressive vascular tumors may similarly show increased susceptibility to the inhibitory effects of beta blockade. Using a panel of hemangioendothelioma and angiosarcoma cell lines, we demonstrate that beta adrenergic inhibition blocks cell proliferation and induces apoptosis in a dose dependent manner. Beta blockade is selective for vascular tumor cells over normal endothelial cells and synergistically effective when combined with standard chemotherapeutic or cytotoxic agents. We demonstrate that inhibition of beta adrenergic signaling induces large scale changes in the global gene expression patterns of vascular tumors, including alterations in the expression of established cell cycle and apoptotic regulators. Using in vivo tumor models we demonstrate that beta blockade shows remarkable efficacy as a single agent in reducing the growth of angiosarcoma tumors. In summary, these experiments demonstrate the selective cytotoxicity and tumor suppressive ability of beta adrenergic inhibition on malignant vascular tumors and have laid the groundwork for a promising treatment of angiosarcomas in humans.

    Objective: To optimize the delay time before the initiation of arterial phase scan in the detection of focal liver lesions in contrast enhanced 5 phase liver CT using the bolus tracking technique. Patients and Methods: Delay - the interval between threshold enhancement of 100 hounsfield unit (HU) in the abdominal aorta and commencement of the first arterial phase scan. Using a 16 slice CT scanner, a plain CT of the liver was done followed by an intravenous bolus of 120 ml nonionic iodinated contrast media (370 mg I/ml) at the rate of 4 mL/s. The second phase scan started immediately after the first phase scan. The portal venous and delay phases were obtained at a fixed delay of 60 s and 90 s from the beginning of contrast injection. Contrast enhancement index (CEI) and subjective visual conspicuity scores for each lesion were compared among the three groups. Results: 84 lesions (11 hepatocellular carcinomas, 17 hemangiomas, 39 other hypervascular lesions and 45 cysts) were evaluated. CEI for hepatocellular carcinomas appears to be higher during the first arterial phase in the 6 seconds delay group. No significant difference in CEI and mean conspicuity scores among the three groups for hemangioma, other hypervascular lesions and cysts. Conclusion: The conspicuity of hepatocellular carcinomas appeared better during the early arterial phase using a bolus tracking technique with a scan delay of 6 seconds from the 100 HU threshold in the abdominal aorta.

    Propranolol, a beta 1 (ADBR1) and beta 2 (ADBR2) adrenergic receptor blocker, accelerates regression of proliferating infantile hemangiomas (IH-P) while not affecting non-involuting congenital hemangiomas (NICH) and nonproliferating IH (IH-NP). To determine the expression of ADBRs in vascular tumors, immunofluorescent staining and confocal microscopy were employed to determine the in situ cellular distribution of ADBRs in formalin-fixed paraffin-embedded tissue sections of IH-P, IH-NP, and NICH. In situ cellular proliferation, indexed by Ki-67 expression, distinguished IH-P (n = 3) from both IH-NP (n = 3) and NICH (n = 2). In IH-P, IH-NP, and NICH tumor sections, both ADBR1 and ADBR2 were co-localized in both endothelial cells (ECs; GLUT1(+) in IH; CD31+ in NICH) and pericytes (smooth muscle actin). We tentatively conclude that either EC and/or pericytes in IH-P could be target(s) of propranolol. Cell proliferation, but not absence of either class of ADBR, distinguished the propranolol responsive IH-P from the nonresponsive IH-NP and NICH. PMID:24009211

    In the past ten years, 28 patients with primary tumors of the liver have been treated. There were 11 benign tumors, including four hamartomas, three patients with focal nodular hyperplasia, and two each with congenital cysts and hemangioma. Hamartomas and masses of focal nodular hyperplasia should be excised when possible, but both are benign lesions; therefore life threatening excisions at the porta hepatis should be avoided. Cysts are often resectable, but when occupying all lobes of the liver, they can be successfully managed by marsupialization into the free peritoneal cavity. If resectable, hemangiomas should be removed; when occupying most of the liver as they often do, patients may be subject to platelet trapping or to cardiac failure. In some instances these lesions have been controlled by steroids, radiation therapy or hepatic artery ligation. Of 17 malignant tumors seen, 12 proved to be hepatoblastomas. Nine of the 12 patients underwent liver resection, of whom four are cured, (33%). There were three children with hepatocellular carcinomas and two with embryonal rhabdomyosarcoma. One child from each of these groups is cured by surgical excision. At present the only known cures in children with primary malignant liver neoplasms have been achieved by operative removal.

    The exact nature of juvenile nasopharyngeal angiofibroma (JNA) is still in dispute. In recent years, the main controversy of its nature has focused on hemangioma and vascular malformation. In this study, the immunolocalization of vascular endothelial growth factor (VEGF), VEGF receptor-1/fms-like tyrosine kinase-1 (VEGFR-1/Flt-1), VEGF receptor-2/fetal liver kinase-1 (VEGFR-2/Flk-1), proliferating cell nuclear antigen (PCNA), and CD34 was investigated in 28 cases of JNA and 20 cases of orbital cavernous hemangiomas (OCH). The immunostaining levels of VEGF, Flt-1, and Flk-1 were higher and more frequent in vascular endothelial cells of JNA than those of OCH (p<0.05). The average microvessel density (MVD) marked by CD34 in JNA was (49.3 ± 9.1)/HPF (high power field), which was higher than OCH (29.1 ± 6.7)/HPF (p<0.05). Immunoreactivity of PCNA was localized in both endothelial and stromal cell components of JNA, but was predominantly seen in the stromal cells. However, no PCNA immunoreactivity was identified in any of the stromal and endothelial cells in cases of OCH. The immunostaining levels of CD34, VEGF, Flt-1, Flk-1, and PCNA in JNA were higher than those in OCH. These data support the view that JNA has biological characteristics of an angiogenic histogenetic tumor. In the future, anti-angiogenic therapy may represent a novel treatment strategy for JNA.

    There are six major steps in the management of patients with neuroendocrine tumors (NETs) (carcinoids and pancreatic endocrine tumors). One of the steps that is increasing in its importance is the need to assess primary tumor location and tumor extent in these patients. Without such information, it is not possible to adequately manage these patients. Conventional imaging studies (CT scan, MRI, ultrasound, angiography), functional localization studies measuring hormonal gradients, endoscopic ultrasound, and most recently, somatostatin receptor scintigraphy (SRS) with [125I-DTPA-DPhe1]-octreotide have all been advocated to localize NETs in different studies. Whereas it is now established that for all NETs, except insulinomas, SRS has the greatest sensitivity, it remains unclear whether this increased sensitivity translates into increased clinical usefulness. It, therefore, remains unclear based on fiscal and clinical considerations what should be the recommended algorithm for the use of the different localization methods. To address this issue, we have recently performed two prospective studies on patients with gastrinomas. In this paper, the methods and results of each are summarized and based on these results, an algorithm for localization studies in NETs is proposed. One study assessed the role of SRS in management in 122 patients and shows that the use of SRS changed management in 47 percent of patients according to six different criteria when the patients were stratified according to their principal management problem. Determining whether liver metastases were present is one of the major goals of tumor localization studies and is frequently a source of confusion because of the difficulty in distinguishing small NETs liver metastases from hemangiomas. In the second study, the ability of SRS and other tumor localization methods to distinguish these two possibilities was assessed in 15 patients with small hemangiomas and 15 patients with small hepatic metastases

    A consecutive series of 50 patients (28 males and 22 females) who underwent hepatic magnetic resonance imaging (MRI) from August to December 2011 were enrolled in this study. The appropriate parameters for abdominal MRI scans were determined by comparing the images (TE = 90 and 128 msec) produced using the half-Fourier acquisition single-shot turbo spin-echo (HASTE) technique at different signal acquisition times. The patients consisted of 15 normal patients, 25 patients with a hepatoma and 10 patients with a hemangioma. The TE in a single patient was set to either 90 msec or 128 msec. This was followed by measurements using the four normal rendering methods of the biliary tract system and the background signal intensity using the maximal signal intensity techniques in the liver, spleen, pancreas, gallbladder, fat, muscles and hemangioma. The signal-to-noise and the contrast-to-noise ratios were obtained. The image quality was assessed subjectively, and the results were compared. The signal-to-noise and the contrast-to-noise ratios were significantly higher at TE = 128 msec than at TE = 90 when diseases of the liver, spleen, pancreas, gallbladder, and fat and muscles, hepatocellular carcinomas and hemangiomas, and rendering the hepatobiliary tract system based on the maximum signal intensity technique were involved (p < 0.05). In addition, the presence of artifacts, the image clarity and the overall image quality were excellent at TE = 128 msec (p < 0.05). In abdominal MRI, the breath-hold half-Fourier acquisition single-shot turbo spin-echo (HASTE) was found to be effective in illustrating the abdominal organs for TE = 128 msec. Overall, the image quality at TE = 128 msec was better than that at TE = 90 msec due to the improved signal-to-noise (SNR) and contrast-to-noise (CNR) ratios. Overall, the HASTE technique for abdominal MRI based on a high-magnetic field (3.0 T) at a TE of 128 msec can provide useful data.

    Summary Background The aim of this study is to describe the technique and to evaluate the results of whole-body magnetic resonance imaging in an asymptomatic population. Material/Methods Between March 2009 and December 2011, 118 consecutive subjects undergoing thorough medical check-up were prospectively included in the study. MRI was performed with a 205-cm moving table, parallel imaging and automatic image composing software. Results In 83 subjects (70%), 103 benign lesions were detected. Two malignant (adrenal and renal carcinoma) lesions and one precancerous (pancreatic mucinous carcinoma) lesion were detected. The most common lesions were renal cysts, liver hemangiomas, liver cysts, thyroid nodules, and uterine leiomyomas. Conclusions WB-MRI is able to cover area from head to toes in one diagnostic work-up, and besides the anatomic regions evaluated by conventional radiological modalities, i.e. brain parenchyma, bones and extremities, can be evaluated in one examination.

    Forty-four patients with intraocular disease were studied by computed tomography (CT); in 19 cases malignant uveal melanoma was considered the likely diagnosis. CT proved to be accurate in determining the location and size of uveal melanomas, demonstrating scleral invasion, and differentiating melanoma from choroidal detachment or angioma, toxocariasis, and senile macular degeneration. On CT, uveal melanomas appeared as hyperdense lesions with slight to moderate contrast enhancement. Tumors thinner than 2 mm could not be seen. Using dynamic CT, the authors noted moderate peak amplitude, normal or delayed tissue transit time, and persistently elevated washout phase (downslope), indicating increased permeability as the result of an impaired tumor blood barrier. Histological types of uveal melanoma could not be differentiated on the basis of circulatory patterns. Dynamic CT may be useful in distinguishing uveal melanoma from choroidal hemangioma or hematoma.

    The smaller anatomy and limited access to instrumentation pose a challenge to the pediatric airway surgeon. The enhanced precision and ability to photocoagulate tissue while operating with the laser enhances the surgeon"s ability to successfully treat unique pediatric conditions such subglottic hemangiomas, congenital cysts, respiratory papillomatosis, and laryngeal or tracheal stenosis. Due to its shallow tissue penetration and thermal effect, the carbon dioxide (CO2) laser is generally considered the laser of choice for pediatric airway applications. The potential for increased scarring and damage to underlying tissue caused by the greater penetration depth and thermal effect of the Nd:YAG and KTP lasers preclude their use in this population. In this review, we will describe the specific advantages of using lasers in airway surgery, the current technology and where the current technology is deficient.

    From the tumor register of the Institute of Pathology of Jena all soft tissue tumors of the head and neck collected between 1959 and 1984 were retrieved and reclassified. 562 out of 646 tumors (87%) were benign. Three quarter of these growths could be diagnosed as nerve sheath tumors (schwannomas and neurofibromas), hemangiomas, fibrohistiocytic tumors and lipomas. 84 tumors were malignant (13%). As the most frequent subtypes we found fibrohistiocytic sarcomas (malignant fibrous histiocytomas and atypical fibroxanthomas), muscularly differentiated sarcomas (rhabdo- and leiomyosarcomas) and unclassified sarcomas. The age and sex distribution as well as the localization and histologic peculiarities were analysed and compared with findings reported in the literature. The significance of knowing such data for diagnostic and differential diagnostic considerations is stressed and exemplified. PMID:3592924

    This first clinical prospective study was conducted to use of technetium-99m immunoglobulin G ((99m)Tc-IgG) as compared with autologous (99m)Tc-red blood cells (RBC) in gated blood pool ventriculography. We studied 12 patients who referred to us for a possible diagnosis of liver hemangioma or infection. Six patients underwent gated planar blood pool (GPBP) acquisition using (99m)Tc-RBC and 6 GPBP acquisition using (99m)Tc-IgG. The use of (99m)Tc-IgG in cardiac blood pool studies provided comparable images to (99m)Tc-RBC. In conclusion, (99m)Tc-IgG, which is readily available and needs only a single injection, may be an attractive alternative to (99m)Tc-RBC for the estimation of various cardiac function parameters like left ventricular function.

    Because of the different step programs concerning the preoperative diagnostic and the onset of therapy for the various types of congenital vascular disorders (CVD) a clear classification is important. One has to discern the vascular malformations, including the port wine stain, from the real hemangiomas which are vascular tumors. As former classification, mostly based on histological findings, showed little evidence to a clinical step program, we developed a descriptive classification which allows an early differentiation between the two groups of CVD. In most cases this can be done by a precise medical history of the onset and development of the disorder, a close look to the clinical signs and by Duplex-Ultrasound and MRI-diagnostic. With this protocol and the case adapted use of different lasers and laser techniques we have not seen any severe complications as skin necrosis or nerve lesions.

    Spinal paragangliomas are very rare neuroendocrine tumors often presenting with low back pain and radicular symptoms; once resected, they often show benign clinical outcomes. Radiographically spinal paragangliomas mimic more commonly described tumors, such as ependymomas, schwannomas, meningiomas, and even hemangiomas, but a “salt and pepper” appearance related to a serpiginous vascular structure is instructive. Indeed, the rarity of this tumor makes the diagnosis rather challenging radiographically. Graded as a WHO Grade I tumor, they are slow-growing with low proliferation indices. Gross total resection is the mainstay of operative treatment but is often limited by tumor adherence to functional nerves. Here, we present a case of this rare tumor and its management, including a review of the pathology and literature related to this tumor. PMID:26623209

    Vascular lesions in childhood are comprised of vascular tumors and vascular malformations. Vascular tumors encompass neoplasms of the vascular system, of which infantile hemangiomas (IHs) are the most common. Vascular malformations, on the other hand, consist of lesions due to anomalous development of the vascular system, including the capillary, venous, arterial, and lymphatic systems. Capillary malformations represent the most frequent type of vascular malformation. IHs and vascular malformations tend to follow relatively predictable growth patterns in that IHs grow then involute during early childhood, whereas vascular malformations tend to exhibit little change. Both vascular tumors and vascular malformations can demonstrate a wide range of severity and potential associated complications necessitating specialist intervention when appropriate. Evaluation and treatment of the most common types of vascular lesions are discussed in this article. [Pediatr Ann. 2016;45(8):e299-e305.]. PMID:27517358

    Some of the more recent advances and newer concepts about certain dermatological conditions are presented. Untoward reactions to drugs, whether to systemic or topical agents, are discussed in detail; emphasis is placed on their frequency and on the diversity of clinical findings. In the management of certain skin tumours (hemangiomas and melanocytic nevi) it is essential that the natural history of the lesion be considered. It is generally agreed that the answer to the problem of staphylococcal infection of the skin will be found in the host rather than the staphylococcus. Keratoacanthoma is a pseudocarcinoma of unknown etiology and sometimes gives rise to considerable difficulty in diagnosis. Diffuse alopecia in women is now a common dermatological problem, the cause of which is unknown. The hair loss associated with it is not permanent. ImagesFig. 1 PMID:13964259

    The association of persistent embryonic arteries and the absence of 1 carotid or vertebral arteries with facial or neck hemangioma or vascular malformation have been frequently described. The abnormalities can involve major or minor vessels. Of 22 patients of our series with this neurocutaneous syndrome, 20 had the origin of both anterior cerebral arteries from the same internal carotid artery. Thirteen patients showed absence or hypoplasia of 1 carotid artery and 10 of 1 vertebral artery; 10 showed persistence of the trigeminal artery; 3 had persistent proatlantal artery; 6 showed the absence of the posterior communicating artery; and 4 had hypoplastic posterior cerebral artery. Other less frequent abnormalities were found in 7 patients. Intellectual level of most patients was either borderline or below normal. Abnormalities in the vascularization and perfusion of the frontal lobes may contribute to the borderline or lower mental level of these patients. PMID:19808986

    RGB (red-green-blue) technique for mapping skin chromophores by smartphones is proposed and studied. Three smartphones of different manufacturers were tested on skin phantoms and in vivo on benign skin lesions using a specially designed light source for illumination. Hemoglobin and melanin indices obtained by these smartphones showed differences in both tests. In vitro tests showed an increment of hemoglobin and melanin indices with the concentration of chromophores in phantoms. In vivo tests indicated higher hemoglobin index in hemangiomas than in nevi and healthy skin, and nevi showed higher melanin index compared to the healthy skin. Smartphones that allow switching off the automatic camera settings provided useful data, while those with “embedded” automatic settings appear to be useless for distant skin chromophore mapping.

    2012-07-01

    Hemorrhagic splenic masses diagnosed as hemangioma or hemangiosarcoma were reviewed. Lymphoid hyperplasia was present in none of the hemangiosarcoma cases and in 27% of the hematoma cases. Siderotic nodules in the capsule or trabeculae were present in 25% of hemangiosarcoma cases and in 36% of hematoma cases. Hemoabdomen was noted in the clinical history of 54% of hemangiosarcoma cases and in 22% of hematoma cases. The average age (10.3 and 9.6 years, respectively), sex ratios (slightly more males), and most common breeds (Labrador Retriever, Golden Retriever, and German Shepherd Dog) were similar for the hemangiosarcoma and hematoma cases. Since lymphoid hyperplasia is much more common in cases of hematoma, the presence of this feature lends support to a diagnosis of hematoma rather than hemangiosarcoma. Signalment, history of hemoabdomen, and presence of siderotic nodules do not point to one diagnosis over the other. PMID:22621950

A retrospective study was conducted and the database of pathology reports from the Surgical Pathology Service of the Department of Pathology and Toxicology, School of Veterinary Medicine, University of Pennsylvania from 1986 to 2010 was searched for canine neoplastic scrotal and non-scrotal cutaneous lesions. Neoplastic lesions were evaluated based on diagnosis, breed, age, and number and location of tumors (scrotal versus non-scrotal cutaneous). Mast cell tumor, melanocytoma, malignant melanoma, vascular hamartoma, hemangiosarcoma, hemangioma, and cutaneous histiocytoma were the most common tumor types identified on the canine scrotum. Breed predispositions and mean age at diagnosis were identified for each tumor type and should be considered when planning surgical excision of a canine scrotal tumor. PMID:24381341

The expression of Tspan-1, Jab1 and p27 was detected in HCC tissues, the tissues around cancer (76 cases), and the normal tissues around the liver hemangiomas (10 cases). The overexpression of Tspan-1 and Jab1 was found in HCC tissues, positively correlated with clinical stage and negatively correlated with survival rate. The expression of p27 was found inversely linked to which of Tspan-1 and Jab1. In conclusion, the expression of Tspan-1, Jab1 and p27 is significantly associated with development of HCC. Overexpression of Tspan-1 and Jab1 suggests poor prognosis but overexpression of p27 may expect good prognosis for patients with HCC. PMID:20890423

    Bacillary angiomatosis is a rather frequent infectious pathology appearing mainly in the skin but can also affect the liver, spleen, heart, bones, lungs, muscles, central nervous system and other organs. The localization of the lesion in the oral cavity is rather rare, as it is evident in the literature. Bacillary angiomatosis can be clinically similar to the Kaposi's sarcoma and histologically confused with angiosarcoma, epitheloid hemangioma and pyogenic granuloma. A case of bacillary angiomatosis of the oral cavity in an immuno-competent patient is described. The high tendency to relapse, the capability in migration and to involve several localizations at the same time have induced the authors to deepen the research to exclude the possibility that it could be a Kaposi's sarcoma or a pyogenic granuloma and to get to an accurate diagnosis in order to resolve the disease.

    Medical ultrasound image edge detection is an important component in increasing the number of application of segmentation, and hence it has been subject of many studies in the literature. In this study, we have classified the liver ultrasound images (US) combining Canny and Sobel edge detectors with fractal analysis in order to provide an indicator about of the US images roughness. We intend to provide a classification rule of the focal liver lesions as: cirrhotic liver, liver hemangioma and healthy liver. For edges detection the Canny and Sobel operators were used. Fractal analyses have been applied for texture analysis and classification of focal liver lesions according to fractal dimension (FD) determined by using the Box Counting method. To assess the performance and accuracy rate of the proposed method the contrast-to-noise (CNR) is analyzed.

    2011-01-01

    Infantile hemangioma (IH), a benign vascular tumor, is the most common tumor of infancy, with an incidence of 5%–10% at the end of the first year. The tumor displays a distinctive life cycle consisting of a proliferating phase, occurring in the first months of life, followed by an involuting phase. Thus, IH represents a unique model of postnatal vasculogenesis, angiogenesis, and vessel regression. Traditionally, corticosteroids were the drug of choice when treatment of IH was indicated. In recent years, beta-blockers, most specifically propranolol, have serendipitously been shown to be an effective pharmacological treatment. This article will focus on the mechanism of action of these two drugs, the old and the new treatments, in slowing the growth and accelerating involution of IH. PMID:22229118

    AIM: To compare the roles of capsule endoscopy (CE) and double-balloon enteroscopy (DBE) in the diagnosis of obscure small bowel diseases. METHODS: From June 2009 to December 2014, 88 patients were included in this study; the patients had undergone gastroscopy, colonoscopy, radiological small intestinal barium meal, abdominal computed tomography or magnetic resonance imaging scan and mesenteric angiography, but their diagnoses were still unclear. The patients with gastrointestinal obstructions, fistulas, strictures, or cardiac pacemakers, as well as pregnant women, and individuals who could not accept the capsule-retention or capsule-removal surgery were excluded. Patients with heart, lung and other vital organ failure diseases were also excluded. Everyone involved in this study had undergone CE and DBE. The results were divided into: (1) the definite diagnosis (the diagnosis was confirmed at least by one of the biopsy, surgery, pathology or the drug treatment effects with follow-up for at least 3 mo); (2) the possible diagnosis (a possible diagnosis was suggested by CE or DBE, but not confirmed by the biopsy, surgery or follow-up drug treatment effects); and (3) the unclear diagnosis (no exact causes were provided by CE and DBE for the disease). The detection rate and the diagnostic yield of the two methods were compared. The difference in the etiologies between CE and DBE was estimated, and the different possible etiologies caused by the age groups were also investigated. RESULTS: CE exhibited a better trend than DBE for diagnosing scattered small ulcers (P = 0.242, Fisher’s test), and small vascular malformations (χ2 = 1.810, P = 0.179, Pearson χ2 test), but with no significant differences, possible due to few cases. However, DBE was better than CE for larger tumors (P = 0.018, Fisher’s test) and for diverticular lesions with bleeding ulcers (P = 0.005, Fisher’s test).

    Vascular lesions may be categorized as proliferative tumors, such as hemangiomas, or nonproliferative malformations that include capillary, lymphatic, venous, arterial, or mixed lesions. Lymphatic malformations are benign localized congenital malformations of the lymphatic system. They may be microcystic or macrocystic lesions or a combination of both. The lesions may also be uniseptate or multiseptate, and are more commonly located in the head and neck or axillary region. Prenatal diagnosis is based on ultrasound and magnetic resonance imaging. Postnatal management largely depends on the size and location of the lesion. This is the first case report of prenatally diagnosed extensive subcutaneous macrocystic venous lymphatic malformation involving the fetal thorax, back, pelvis, and lower extremities. Prenatal course and postnatal management are described. This report will aid other specialists in the field of prenatal diagnosis and postnatal surgery in the evaluation and management of these patients. PMID:26199796

    2013-01-01

    Endothelial cell (EC)-derived neoplasias range from benign hemangioma to aggressive metastatic angiosarcoma, which responds poorly to current treatments and has a very high mortality rate. The development of treatments that are more effective for these disorders will be expedited by insight into the processes that promote abnormal proliferation and malignant transformation of human ECs. The study of primary endothelial malignancy has been limited by the rarity of the disease; however, there is potential for carefully characterized EC lines and animal models to play a central role in the discovery, development and testing of molecular targeted therapies for vascular neoplasias. This review describes molecular alterations that have been identified in EC-derived neoplasias, as well as the processes that underpin the immortalization and tumorigenic conversion of ECs. Human EC lines, established through the introduction of defined genetic elements or by culture of primary tumor tissue, are catalogued and discussed in relation to their relevance as models of vascular neoplasia.

    Fluid-fluid levels have commonly been reported to occur in aneurysmal bone cysts but have also been seen in telangiectatic osteosarcoma, chondroblastoma, and giant cell tumor of bone. The authors reviewed their experience with nine bone and three soft-tissue tumors that showed fluid-fluid levels on computed tomographic or magnetic resonance images. The bone tumors included fibrous dysplasia, simple bone cyst, recurrent malignant fibrous histiocytoma of bone, two classical osteosarcomas, and four aneurysmal bone cysts. The soft-tissue tumors included soft-tissue hemangioma and two synovial sarcomas. Except for aneurysmal bone cysts, these types of tumors have not been reported to be associated with fluid-fluid levels. Radiologic-pathologic correlation was available in seven patients; in all seven, the fluid-fluid levels indicated prior hemorrhage. The authors conclude that the presence of fluid-fluid levels in bone or soft-tissue tumors cannot be considered diagnostic of any particular tumor. PMID:2160676

    The differential diagnosis of a buccal soft tissue mass containing calcified bodies includes a phlebolith associated with a vascular lesion, such as a hemangioma with a calcified intravascular thrombus, and diseases such as sialolithiasis, traumatic myositis ossificans, calcified acne lesion, neoplasm, and calcified lymph nodes, including tuberculosis. The appearance of the calcified bodies on plain radiographs may help to differentiate these entities. Computed tomography, magnetic resonance imaging, and ultrasonography are also useful for differentiating the soft tissue lesions. We report a 17-year-old girl with a small mass containing a calcified body in the anterior portion of the masseter muscle. The mass was resected surgically and evaluated histologically, confirming the diagnosis of phlebolith. We also discuss the differential diagnosis of a buccal soft tissue mass containing calcifications and suggest that the immunolocalization of CD31 at capillaries in the mass may help to diagnose as a phlebolith.

    We report a case of a 46 year old female patient with nasal hemangiopericytoma. She complained of left nasal congestion, pus snot for 10 years, sometimes with left nasal bleeding. Physical examination: in the left nasal tract saw red soft neoplasm, roughness surface, easy bleeding when touched. Sinus CT shows: bilateral maxillary sinus, ethmoid sinus, sphenoid sinus and the left posterior nasal cavity lesions, considering inflammation with the formation of polyps, tumor not excluded. The left nasal cavity neoplasm biopsy shows: hemangioma of left nasal cavity. After admission in general anesthesia, we do transnasal endoscopic sinus openning operation and the left nasal cavity neoplasm resection. Postoperative pathological examination shows: the left nasal cavity hemangiopericytoma. Immunohistochemical showed: Vimentin(+), Smooth muscle actin(+), Desmin(-), endothelial cells CD31(-) and CD34(-). No postoperative radiotherapy or chemotherapy, no tumor recurrence. After one year of follow-up, the contact was lost. PMID:26281069

    While pediatric orbital tumors are most often managed in tertiary care centers, clinicians should be aware of the signs of intraocular and orbital neoplasms. In the pediatric population, a delay in diagnosis of orbital and intraocular lesions, even if benign, can lead to vision loss and deformity. Intraocular lesions reviewed are retinoblastoma, medulloepithelioma, and retinal astrocytic hamartoma. Orbital neoplasms reviewed are rhabdomyosarcoma, neuroblastoma metastases, optic pathway glioma, plexiform neurofibroma, leukemia, lymphoprolipherative disease, orbital inflammatory syndrome, dermoid and epidermoid inclusion cysts, and Langerhans' cell histiocytosis. Vascular lesions reviewed are infantile hemangioma and venous lymphatic malformation. In conjunction with clinical examination, high-resolution ophthalmic imaging and radiologic imaging play an important role in making a diagnosis and differentiating between benign and likely malignant processes. The radiologic imaging characteristics of these lesions will be discussed to facilitate prompt diagnosis and treatment. The current treatment modalities and management of tumors will also be reviewed. PMID:23577029

    The computed tomographic scans (CT) of 84 patients with untreated soft-tissue neoplasms were studied, 75 with primary and nine with secondary lesions. Each scan was evaluated using several criteria: homogeneity and density, presence and type of calcification, presence of bony destruction, involvement of multiple muscle groups, definition of adjacent fat, border definition, and vessel or nerve involvement. CT demonstrated the lesion in all 84 patients and showed excellent anatomic detail in 64 of the 75 patients with primary neoplasms. The CT findings were characteristic enough to suggest the histology of the neoplasm in only 13 lesions (nine lipomas, three hemangiomas, one neurofibroma). No malignant neoplasm had CT characteristics specific enough to differentiate it from any other malignant tumor. However, malignant neoplasms could be differentiated from benign neoplasms in 88% of the cases.

    Theoretical and experimental analysis of the efficiency of application of 2 micrometers pulsed holmium laser for cosmetic and plastic surgery and dermatology is carried out. Preliminary experiments were carried out on rats. Solid state 2 micrometers pulsed laser was allowed to operate in free running mode with pulse energy up to 1.5 J and pulse repetition rate up to 5 Hz. To deliver emission to the object a flexible quartz fiber without further focusing of 2.5 m in length and 400 micrometers of the core diameter was used. The effect of the different power density emission on the skin was studied. The second stage was the study of the influence of 2 micrometers emission on human skin. The results of the removal of hemangioma, papilloma, telangiectasia, nevus, nevus acantholytic, xanthelasma palpebral, verruca, chloasma, pigmental spots, tattoos, etc. are presented. Precision, simplicity, efficiency, and the high cosmetic effect of these operations is noted.

    Vascular skin lesions comprise a wide and heterogeneous group of malformations and tumors that can be correctly diagnosed based on natural history and physical examination. However, considering the high incidence of such lesions, a great number of them can be misdiagnosed. In addition, it is not so rare that an aggressive amelanotic melanoma can be misdiagnosed as a vascular lesion. In this regard, dermoscopy and confocal laser microscopy examination can play a central role in increasing the specificity of the diagnosis of such lesions. In fact, the superiority of these tools over clinical examination has encouraged dermatologists to adopt these devices for routine clinical practice, with a progressive spread of their use. In this review, we will go through the dermoscopic and the confocal laser microscopy of diagnosis of most frequent vascular lesions (i.e., hemangiomas angiokeratoma, pyogenic granuloma, angiosarcoma) taking into particular consideration the differential diagnosis with amelanotic melanoma.

    This text covers all aspects of radiation therapy for treatment of pediatric cancer. The book describes the proper use of irradiation in each of the malignancies of childhood, including tumors that are rarely encountered in adult practice. These include acute leukemia; supratentorial brain tumors; tumors of the posterior fossa of the brain and spinal canal; retinoblastoma and optic nerve glioma; neuroblastoma; Hodgkin's disease; malignant lymphoma; Ewing's sarcoma; osteosarcoma; rhabdomyosarcoma; Desmoid tumor; Wilms' tumor; liver and biliary tumors; germ cell and stromal cell tumors of the gonads; endocrine, aerodigestive tract, and breast tumors; Langerhans' cell histiocytosis; and skin cancer and hemangiomas. For each type of malignancy, the authors describe the epidemiology, common presenting signs and symptoms, staging, and proper diagnostic workup. Particular attention is given to the indications for radiation therapy and the planning of a course of radiotherapy, including the optimal radiation dose, field size, and technique.

    Primary tumors of spine are rare accounting for less than 5% of new bone tumors diagnosed every year. These tumors may exhibit characteristic imaging features that can help in early diagnosis and improved prognosis. Plasmacytoma/multiple myeloma and lymphoproliferative tumors are the most common malignant primary spinal tumors. Hemangioma is the most common benign tumor of the spine. Computed tomography is useful to assess tumor matrix and osseous change. Magnetic resonance is useful to study associated soft tissue extension, marrow infiltration, and intraspinal extension. Confusing one tumor with the other based on only imaging findings is not uncommon. However, radiologic manifestations of these tumors need to be correlated with the age, sex, location, and presentation to arrive at a close clinical diagnosis. PMID:27413280
