    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.

    Fingers often suffer trauma and the clinician is continuously faced with the difficult task of clarifying the distinction between a hemangioma and a traumatic lesion. This study was undertaken to examine ten cases in which a small skin mass located on a finger had been diagnosed preoperatively as hemangioma. Our results showed that seven masses were confirmed pathologically as hemangioma (five cavernous hemangiomas and two capillary hemangiomas), two as traumatic thrombosis and one varix. The clinical manifestations of the two cases of traumatic thrombosis were related to those of hemangioma. In the varix, endothelial proliferation was observed in the area of the thrombosis. This phenomenon is called "intravascular papillary endothelial hyperplasia", and can confuse the differential diagnosis between a vascular neoplasm and a traumatic thrombosis. Our findings demonstrate that since the traumatic lesions were firmer than the hemangiomas, hardness on physical examination may be a helpful indicator in the differential diagnosis of a hemangioma and a traumatic lesion.

    Though hemangiomas of the bone are quite common, calvarial (skull) cavernous hemangiomas are relatively rare pathologies. Calvarial hemangiomas are usually small and asymptomatic. However, they may occasionally grow in size to achieve large sizes and can present as a palpable swelling. We present a child with massive temporo-parieto-occipital calvarial cavernous hemangioma, who was managed with a multimodal approach with excellent cosmetic and neurologic outcome. PMID:25878743

  10. Papillary hemangiomas and glomeruloid hemangiomas are distinct clinicopathological entities.

    2010-02-01

    The author reviews and compares the clinicopathological features of papillary hemangiomas and glomeruloid hemangiomas, 2 rare, cutaneous intravascular capillary-type vascular lesions with overlapping morphological details. Immunostaining for collagen IV highlighted discriminating features in these lesions. Thin basement membranes and glomeruloid architecture are typical of glomeruloid hemangiomas, whereas papillae with thick mantles of a basement membrane- like matrix enveloping pericytes are prominent in papillary hemangiomas. Thus, collagen IV staining patterns provide further evidence that papillary and glomeruloid hemangiomas represent distinct histopathological entities. This additional technique should allow pathologists to readily distinguish between the lesions and make a proper diagnosis. What is important is that glomeruloid hemangiomas-often presenting in a spectrum of multiple cutaneous vascular lesions, including cherry hemangiomas-are a hallmark of POEMS (acronym for polyneuropathy, oganomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) syndrome and/or multicentric Castleman's disease, whereas papillary hemangiomas clinically present as innocent solitary cutaneous hemangiomas in otherwise healthy individuals.

    Capillary hemangioma (capillary lobular hemangioma) and cavernous hemangioma (venous malformation) are relatively common oral tumors/malformations and are characterized by increased numbers of normal and abnormal blood vessels. However, the causes of these lesions are not well understood. CD105 (endoglin) is predominantly expressed in proliferating blood endothelial cells (ECs). We analyzed expressions of CD105, CD34, von Willebrand factor, Ki-67, cyclooxygenase-2 (COX-2), and vascular endothelial growth factor (VEGF)-A in 31 capillary hemangiomas and 34 cavernous hemangiomas. Staining scores were calculated as the product of the proportion score and intensity score. Morphologically normal oral mucosa specimens (n = 10) were simultaneously evaluated as normal controls. As compared with cavernous hemangiomas and normal controls, capillary hemangiomas had higher staining scores for CD105, VEGF-A, and COX-2. The Ki-67 labeling index was significantly higher in capillary hemangiomas than in cavernous hemangiomas and normal controls (P < 0.01). These findings suggest that the biological characteristics of capillary and cavernous hemangiomas are quite different. The ECs of capillary hemangiomas actively proliferated and were generally regulated by VEGF-A. In contrast, the ECs of cavernous hemangiomas lacked proliferative activity. These results suggest that angiogenesis and vasodilatation of pre-existing blood vessels are important in the development of capillary hemangioma and cavernous hemangioma, respectively.

    We describe a case of cardiac cavernous hemangioma with coexisting pulmonary cavernous hemangiomas and hepatic hemangioma. A 35-year-old woman who had previously received a living donor liver transplant to cure giant hepatic hemangioma was seen because of chest pain. A cardiac neoplasm and multiple pulmonary nodules were detected. The tumor was surgically removed, and biopsy specimens were taken from the lung nodules. Histopathologic examination confirmed that both lesions were cavernous hemangiomas. The patient was discharged without adverse events postoperatively. Cardiac hemangioma is an extremely rare entity; the present case is unique for its multiorgan involvement. Suspicion of this entity should be aroused if the imaging manifestation suggests a vascular nature.

    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.

    We describe for the first time a rare coexistence of a cardiac cavernous hemangioma with multiple pulmonary cavernous hemangiomas. Computed tomography revealed bilateral pulmonary nodules, left pleural effusion, and pericardial effusion. Positron emission tomography showed a pericardial neoplasm. Pathologically, multiple large dilated vascular spaces, lined by a single layer of endothelial cells and filled with blood, were revealed in both the cardiac tumor and the pulmonary nodules. Immunohistochemical examination of the lining cells showed positivity for CD31, FLI1, FVIII, and CD34. Taken together, these findings led to the diagnosis of cardiac cavernous hemangioma and multiple pulmonary cavernous hemangiomas.

    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

Glomeruloid hemangioma appears specific to polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes syndrome (POEMS), and is usually, but not always, related to Castleman's disease. We herein report two cases with glomeruloid hemangioma, without any features of the POEMS syndrome. Glomeruloid hemangioma requires a high index of suspicion for diagnosis. It could rarely present as a solitary finding, without any evidence of an underlying POEMS syndrome. PMID:23716835

    Multiple cutaneous infantile hemangiomas have been associated with hepatic hemangiomas. Screening of infants with five or more cutaneous infantile hemangiomas with abdominal ultrasound is often recommended. The aim of this study was to determine the frequency with which hepatic hemangiomas occur in infants with five or more cutaneous infantile hemangiomas compared to those with one to four cutaneous infantile hemangiomas and to characterize the clinical features of these hepatic hemangiomas. A multicenter prospective study of children with cutaneous infantile hemangiomas was conducted at pediatric dermatology clinics at Hemangioma Investigator Groups sites in the United States, Canada, and Spain between October 2005 and December 2008. Data were collected, and abdominal ultrasonography was performed on infants younger than 6 months old with five or more cutaneous infantile hemangiomas and those with one to four cutaneous infantile hemangiomas. Twenty-four (16%) of the 151 infants with five or more cutaneous infantile hemangiomas had hepatic hemangiomas identified on abdominal ultrasound, versus none of the infants with fewer than five (p = 0.003). Two of the 24 infants with hepatic hemangiomas received treatment specifically for their hepatic hemangiomas. Infants with five or more cutaneous infantile hemangiomas have a statistically significantly greater frequency of hepatic hemangiomas than those with fewer than 5. These findings support the recommendation of five or more cutaneous infantile hemangiomas as a threshold for screening infants younger than 6 months old for hepatic hemangiomas but also demonstrate that the large majority of these infants with hepatic hemangiomas do not require treatment.

  20. Signaling mechanisms in infantile hemangioma

    2010-01-01

    Purpose of review Infantile hemangioma is a common vascular tumor with a unique lifecycle: rapid growth in infancy, followed by a period of involution, leading to complete regression. This review summarizes recent studies of molecular mechanisms of hemangioma formation and places new findings and hypotheses in the context of past accomplishments. Recent findings The new work identifies a novel signaling pathway for vascular growth factor and extracellular matrix regulation in vascular endothelial cells and provides a basis for novel therapeutic strategies. In hemangioma-derived endothelial cells defects in a vascular endothelial growth factor receptor/integrin complex reduce the expression of a vascular endothelial growth factor decoy receptor. As a consequence, hemangioma endothelial cells exhibit constitutive vascular endothelial growth factor signaling. Germ-line mutations in components of the growth factor receptor/integrin complex in some hemangioma patients, and somatic mutations in a phosphatase in sporadic hemangioma specimens, raise the possibility that hemangioma formation involves a combination of germline risk factor mutations and somatic mutations, similar to what recent studies have shown is the case for venous malformations. Summary Alterations in pathways that negatively control vascular endothelial growth factor signaling in vascular endothelial cells are responsible for the formation and rapid growth of infantile hemangiomas.

    Primary thyroid hemangiomas are extremely rare, and only a few cases have been previously reported. Primary hemangiomas are developmental anomalies resulting from the inability of the angioblastic mesenchyme to form canals. Thyroid hemangiomas are generally considered difficult to diagnose preoperatively because of their low incidence and nonspecific imaging findings. Here we report 2 cases of thyroid hemangiomas that were diagnosed correctly on preoperative sonography. Our cases showed similar sonographic findings, such as well-circumscribed hypoechoic lesions with internal channel-like linear lines, and bloody content was aspirated during fine-needle aspirations. Our report shows that thyroid hemangiomas can be diagnosed correctly by sonography with or without confirmation of bloody content in the lesions by fine-needle aspiration.

    Intraosseous hemangioma is a benign vascular neoplasm, which is mostly seen in vertebrae, maxillofacial bones, and long bones. Intraosseous hemangioma is rarely seen on jaw bones compared to other skeletal bones and usually occurs in the cavernous form. Capillary intraosseous hemangioma of jaws is an uncommon form of intraosseous hemangioma and has not been thoroughly described so far. In this study, a case of capillary intraosseous hemangioma of the mandible was presented with relevant literature review.

    Benign masses arising from facial bones have been reported several times in the literature. Hemangiomas are one of the uncommon benign tumors. In this study, the authors aimed to present a rare patient of zygomatic intraosseos hemangioma and their management. A 40-year-old woman with a mass in her left lateral cantus admitted to our clinic. Preoperative computed tomography and magnetic resonance imaging revealed an osseos mass in her left zygoma. The authors conclude that it should be kept in mind that although they are very rare benign tumors, intraosseos hemangiomas can cause facial masses. Meticulous radiologic examination can give important clues for differential diagnosis before the surgery.

    Hemangioma is the clinical term for a benign vascular neoplasm due to proliferation of the endothelial lining of blood vessels. Their most frequent location is the body skin and oral mucosa. One of the treatment modalities for hemangiomas is intralesional injection of sclerosing agents which cause the damage of blood vessels followed by their obliteration. The objective of the study was to describe the facility of application and evaluate the efficiency of sclerotherapy with aethoxysklerol 1%. Method. The case presented with intraoral submucosal hemangioma of the cheek was treated by intralesional injection of aethoxysklerol 3% diluted in water for injections at a 4 : 1 ratio (0.75%) at the first appointment and 3 : 1 (1%) at the second appointment. The effect of sclerotherapy was evaluated on the following visits in time intervals of two weeks. Results. The hemangioma disappeared without complications after the second injection of aethoxysklerol 1%. The successful results of the study were comparable to the data of literature with variations according to the used sclerosant agent, its concentration, the number of injections, and the intervals between each session. Conclusion. Since sclerotherapy is a very effective, inexpensive, and easy-to-apply treatment, it should be the treatment of choice, especially for intraoral superficial hemangiomas. PMID:27994889

    Symptomatic vertebral hemangiomas during pregnancy are rare, as only 27 cases have been reported in the literature since 1948. However, symptomatic vertebral hemangiomas can be responsible for spinal cord compression, in which case they constitute a medical emergency, which raises management difficulties in the context of pregnancy. Pregnancy is a known factor responsible for deterioration of these vascular tumors. In this paper, the authors report 2 clinical cases of symptomatic vertebral hemangiomas during pregnancy, including 1 case of spontaneous fracture that has never been previously reported in the literature. The authors then present a brief review of the literature to discuss emergency management of this condition. The first case was a 28-year-old woman at 35 weeks of gestation, who presented with paraparesis. Spinal cord MRI demonstrated a vertebral hemangioma invading the body and posterior arch of T-3 with posterior epidural extension. Laminectomy and vertebroplasty were performed after cesarean section, allowing neurological recovery. The second case involved a 35-year-old woman who presented with spontaneous fracture of T-7 at 36 weeks of gestation, revealing a vertebral hemangioma with no neurological deficit, but it was responsible for pain and local instability. Treatment consisted of postpartum posterior interbody fusion. With a clinical and radiological follow-up of 2 years, no complications and no modification of the hemangiomas were observed. A review of the literature reveals discordant management of these rare cases, which is why the treatment course must be decided by a multidisciplinary team as a function of fetal gestational age and maternal neurological features.

    2014-01-01

    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 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.

    Today vertebral hemangioma is not completely understood entity, neither its pathogenesis nor optimal treatment is determined. Nowadays in majority of clinics in this country ineffective radiotherapy remains the first-line treatment. We analyzed results of treatment of 205 patients (286 lesions) with aggressive hemangiomas operated in Department of Neurosurgery of Military Medical Academy and Department of Nuclear Medicine of of Russian Scientific Center of Radiological and Surgical Technologies (Saint-Petersburg, Russia) since 1999 till 2009. Percutaneus vertebroplasty was performed in 167 lesions, radiotherapy was applied in 119 aggressive hemangiomas. Vertebroplasty is more effective for treatment of aggressive hemangiomas in comparison with radiotherapy. Signs of hemangiomas aggression, indications for surgery, and tactics of management were determined. Use of percutaneous vertebroplasty for treatment of aggressive hemangiomas resulted in fast recovery of the patients. This procedure is minimally invasive, it reduces hospital stay and duration of recovery.

    Vertebral hemangiomas are common lesions and usually considered benign. A rare subset of them, however, are characterized by extra-osseous extension, bone expansion, disturbance of blood flow, and occasionally compression fractures and thereby referred to as aggressive hemangiomas. We present a case of a 67-year-old woman with progressive paraplegia and an infiltrative mass of T4 vertebra causing mass effect on the spinal cord. Multiple conventional imaging modalities were utilized to suggest the diagnosis of aggressive hemangioma. Final pathologic diagnosis after decompressive surgery confirmed the diagnosis of an osseous hemangioma.

    POEMS syndrome is a paraneoplastic manifestation associated with hematopoietic disorders such as multiple myeloma and Castleman disease. POEMS is an acronym for the main clinical features of the syndrome, namely, Polyneuropathy, Organomegaly, Endocrinopathy, M protein, and Skin abnormalities. Glomeruloid hemangiomas are considered to be a specific clinical marker of POEMS syndrome. However, while they are not pathognomonic, their presence should raise suspicion of this syndrome or alert clinicians to its possible future development, as these lesions can appear years before the onset of the syndrome. We report the cases of 2 women with plasma cell dyscrasias and sudden onset of lesions with a vascular appearance and histologic findings consistent with glomeruloid hemangioma. Recognition of this vascular tumor is important for the early diagnosis of POEMS syndrome.

Preoperative diagnosis of maxillary sinus hemangioma is important since these lesions can frequently cause a large amount of hemorrhage during surgery.

    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.

    We retrospectively studied 31 patients with painful bone (15 patients) and soft-tissue (16 patients) hemangiomas treated with 39 embolizations using N-2-butyl cyanoacrylate from 2003 to 2010. The mean tumor size before embolization was 6 cm for bone and 7 cm for soft-tissue hemangiomas. The technique of embolization was the same for bone and soft-tissue lesions. Preoperative embolization was done in six patients, while the remaining patients had embolization as only treatment. The mean follow-up was 47 months (11-89 months). The clinical and imaging effect of treatment was evaluated at follow-up with a pain score scale, tumor size, and ossification. In four patients, embolization was not feasible because of the inability to catheterize and low blood flow of the feeding vessels. Nine patients with bone and 10 with soft-tissue hemangiomas experienced complete pain relief. Four patients with bone and four with soft-tissue hemangiomas experienced recurrence of pain and were treated with repeat embolization. Re-recurrences were not observed in any of the patients with soft-tissue hemangiomas until the period of this study. Ossification and tumor size reduction were higher for bone hemangiomas. Embolization-related complications were more common for soft-tissue hemangiomas.

    A 13-month-old Standardbred Colt had a recurrent hemangioma at the level of the coronary band. Multiple excisions had led to a nonhealing skin and hoof defect. Using 14 MV electrons, a total dose of 36 Gy was administered, given as six fractions of 6 Gy twice a week. Wound healing by second intention was achieved over the next 4 months and the colt began race training 6 months after the end of therapy. Twenty months later the colt is sound and there is no evidence of tumor recurrence.

    The authors describe the case of a 48-year-old man found to have the first reported intramedullary spinal cord spindle cell hemangioma. Previous research indicates that spindle cell hemangiomas are rarely found in the spine. Only 3 previous cases exist, all in the intradural, extramedullary space. In the present case, gross-total resection of the tumor was possible with no loss of function from baseline. This report presents the successful resection of the first reported intramedullary spindle cell hemangioma and reports 4-month follow-up, demonstrating the biological behavior of this rare tumor.

    Two patients with extra-axial cavernous hemangioma who presented with headache and oculovisual disturbances were investigated with computed tomography and magnetic resonance imaging. The lesions masqueraded as basal meningioma, but this diagnosis was not supported by magnetic resonance spectroscopy in one patient. Cerebral angiography with embolization was indicated in one patient, but embolization was not justified in the other. Both patients underwent a pterional craniotomy. The lesions were extradural and highly vascular, necessitating excessive transfusion in one patient in whom gross total resection was achieved, and precluding satisfactory removal in the other. There was no mortality. Transient ophthalmoplegia, the only complication in one patient, was due to surgical manipulation of the cavernous sinus; it resolved progressively over 3 months. Extra-axial skull base cavernous hemangiomas are distinct entities with clinical and radiological characteristics that differ from those of intraparenchymal cavernous malformations. They can mimic meningiomas or pituitary tumors. In some cases, magnetic resonance spectroscopy may narrow the differential diagnoses. Surgical resection remains the treatment of choice, facilitated by preoperative embolization to reduce intraoperative bleeding and by the application of the principles of skull base surgery. Fractionated radiotherapy is an alternative in partial or difficult resections and in high-risk and elderly patients. ImagesFigure 1Figure 2Figure 3Figure 4 PMID:17167631

    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.

    Cutaneous hemangioma is a benign vascular tumor of infancy with an initial proliferating period that appears between 1 to 2 weeks of life, extends during 18 months to 2 years of life, and then slowly regresses during several years until it disappears completely. They are characterized by endothelial cell proliferation followed by diminishing hyperplasia and progressive fibrosis. Vascular malformations are present at birth, grow commensurately with the child, and are characterized histologically by a normal rate of endothelial cell turnover, flat endothelium, thin (normal) basal membrane and normal mast cells. These cutaneous anomalies are commonly associated with cerebellar malformations, main cerebral arteries anomalies, congenital cardiac anomalies and/or coarctation of the aorta and persistence of embryonic arteries. Cutaneous hemangiomas can be associated with intracranial or extracranial hemangiomas that regress at the same time as the cutaneous hemangiomas. Cutaneous hemangiomas may show different types of color. Cutaneous red-to-purple hemangiomas are uncommon and their bright-red color is evident from the first weeks of life and remains unaltered until the hemangioma disappears. The intracranial angiographic studies in our series of more than 50 cases with facial hemangioma showed that patients with red-to-purple hemangiomas are commonly associated with localized leptomeningeal hemangiomas either in the ipsilateral or contralateral side. These leptomingeal hemangiomas were visualized only by MR enhanced with gadolinium. Involution of the cutaneous and leptomeningeal hemangiomas seems to occur simultaneously as in other types of external and internal hemangiomas.

    Abstract Rationale: Urethral hemangiomas commonly occur in men or elderly women. We presented a rare case of urethral hemangioma in a prepubertal female patient. Patients concerns: An 8-year-old girl had the complaints of bloody staining of clothing, a foul perineal odor, and urethral pain. She was brought to our genitourinary outpatient department for survey and a single, 1-cm compressible reddish nodule at the 10-2 o’clock position in the distal urethra was found. Diagnoses: Urethral hemangioma in a prepubertal girl was diagnosed after excision of the urethral nodule. Interventions: Excision with 8 “stay” sutures in the protruding urethral mucosa was performed. Outcomes: Normal micturition without symptom recurrence was noted at the 3-month follow-up. Lessons: Urethral hemangioma is also found in prepubertal female patient. Increased physician awareness and early recognition of a urethral hemangioma can avoid unnecessary examinations and patient anxiety. The procedure of excision with 8 “stay” sutures in the protruding urethral mucosa facilitates mobilization from the distal urethra and provides a good surgical view of abnormal proliferative blood vessels. Therefore, the lesion can be removed as clean as possible. PMID:28353601

    PHACE is an acronym to describe the association of posterior fossa brain malformations, hemangiomas, arterial anomalies, coarctation of the aorta, cardiac defects, and eye abnormalities. More than 200 cases have been reported. The present report presents the cases of two female infants with PHACE syndrome, both of whom had additional congenital defects of subependymal gray matter heterotopia, craniofacial arterial anomalies, and pituitary dysfunction. One had an extensive segmental facial hemangioma with ipsilateral intracranial hemangiomas. The other had multiple cutaneous hemangiomas, but no segmental facial hemangioma. These two cases suggest a further expansion of the spectrum of PHACE to include other forms of disordered cerebral development and endocrine dysfunction.

    Nine patients with cavernous hemangioma of the liver were examined by nuclear magnetic resonance imaging (MRI) with a 0.5 T superconductive magnet. Spin-echo technique was used with varying time to echo (TE) and repetition times (TR). Results were compared with /sup 99m/Tc red blood cell (RBC) scintigraphy, computed tomography (CT), echography, and arteriography. Four illustrated cases are reported. It was possible to establish a pattern for MRI characteristics of cavernous hemangiomas; rounded or smooth lobulated shape, marked increase in T1 and T2 values as compared with normal liver values. It is concluded that, although more experience is necessary to compare the specificity with that of ultrasound and CT, MRI proved to be very sensitive for the diagnosis of liver hemangioma, especially in the case of small ones which may be missed by /sup 99m/Tc-labeled RBC scintigraphy.

    We report a case of right ventricular hemangioma which is extremely rare. It was situated on the anterior wall of the right ventricle and protruded into the out flow tract. Aortography revealed that the main feeding artery was the conus brunch. Operation was done under cardiopulmonary bypass. The tumor was situated between LAD and RCA and resected incompletely, because of the fear that complete removal would occlude blood flow of both LAD and RCA. Histological examination disclosed intramuscular hemangioma. The postoperative course was uneventful. To our knowledge, this is the second resected case in the Japanese literature and the eighth case in the world literature.

    Tc-99m labeled red blood cell scintigraphy is a valuable, noninvasive technique for differentiating hepatic hemangioma from other lesions by demonstrating a 'perfusion blood pool mismatch.' The characteristic finding on dynamic CT scan of peripheral and subsequent central enhancement is not usually seen on Tc-99m RBC angiography, probably due to rapid mixing and dilution of the radionuclide and low resolution of the gamma camera. A case of multiple hepatic hemangioma is presented in which Tc-99m RBC dynamic angiography demonstrated peripheral enhancement with subsequent central filling. In addition, delayed static images showed more hepatic lesions.

    Hemangioma is the most common benign tumor of the liver. An accurate diagnosis of such tumor is essential for proper management of patients with hepatic cavernous hemangioma (HCH). Noninvasive diagnosis of HCH can be made using sequential Tc-99m RBC scintigraphy by demonstrating a perfusion-blood pool mismatch. In addition, a case of HCH was observed which demonstrated peripheral enhancement with subsequent central enhancement on a sequential Tc-99m RBC blood pool scintigraphy. It is felt that this scintigraphic finding is pathognomonic for HCH.

    Infantile hemangioma is a vascular neoplasm and is one of the most common tumors diagnosed in young children. Although most hemangiomas are harmless and involute spontaneously, some show severe progression, leading to serious complications, such as high output cardiac failure, ulcerations, compression of the trachea or deprivation amblyopia, depending on their size and localization. However, the pathogenesis and cause of hemangioma are largely unknown to date. The goal of this study was to identify markers that could predict hemangiomas with aggressive growth and severe progression that would benefit from early intervention. By using a PCR-based screening approach, we first confirmed that previously known markers of hemangioma, namely FGF2 and GLUT1, are highly expressed in hemangioma. Nevertheless, these genes did not show any differential expression between severely progressing tumors and mild tumors. However, transcriptional upregulation of several Hedgehog signaling components, comprising the ligand Sonic Hedgehog (SHH),the transcription factor GLI2 and its target gene FOXA2 were detected in extremely aggressive hemangioma specimens during the proliferation phase. Notably, GLI2 was even overexpressed in involuting hemangiomas if they showed an aggressive growth pattern. In conclusion, our data suggest that overexpression of the Hedgehog components SHH, GLI2 and FOXA2 might be used as markers of an aggressive hemangioma that would benefit from too early intervention, while FGF2 and GLUT1 are more general markers of hemangiomas.

    Tc99m labeled red blood cell blood flow and delayed static blood pool imaging is widely accepted as a reliable, accurate method for the diagnosis of hepatic hemangiomata. The purpose of this study is to assess the relative value of SPECT blood pool imaging in the evaluation of hepatic hemangionata. A total of 68 patients, including 21 patients with proven hepatic cavernous hemangiomas, were studied using both planar and SPECT imaging techniques. All patients underwent multi-phase evaluation which included a hepatic flow study, immediate planar images of the liver, followed by a 360/sup 0/ tomographic (SPECT) study and subsequent 60 minute delayed static planar hepatic blood pool images. All 21 patients with proven hepatic hemangiomas had a positive SPECT exam and 17 of the 21 (81%) patients had a positive planar exam. In the 21 patients, there were a total of 36 hemangiomas ranging in size from .7 cm to 13 cm. The SPECT imaging technique correctly identified all 36 lesions (100%) where as planar imaging detected 25 of the 36 lesions (69.4%). In all the remaining patients (10-normal, 17-metastatic disease, 12-hepatocellular disease, 6-hepatoma, 2-liver cysts), both the planar and SPECT imaging techniques were interpreted as showing no evidence of focal sequestration of red blood cells. SPECT hepatic blood pool imaging represents an improvement in the evaluation of hepatic hemangioma as a result of a reduction in imaging time (less than thirty minutes), improved spatial resolution and greater overall accuracy.

    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.

    Conservative surgical strategies are appropriate for most symptomatic hemangiomas causing cord compression without instability or deformity. Even so, complete intralesional spondylectomy following embolization of aggressive vertebral hemangiomas with circumferential vertebral involvement can be safely accomplished. Such a spondylectomy can also prevent recurrence of hemangiomas. Transarterial embolization without decompression is an effective treatment for painful intraosseous hemangiomas. Vertebroplasty is useful for improving pain symptoms, especially when vertebral body compression fracture has occurred in patients without neurological deficit, but is less effective in providing long-term pain relief.

    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

    Infantile hemangiomas can be associated with congenital anomalies such as PHACE syndrome with facial hemangiomas and genitourinary and spinal anomalies in the setting of lower body hemangiomas. We describe five infants in whom segmental hemangiomas involving the upper torso and extremities with absent or small facial hemangiomas were associated with structural anomalies similar to those reported with PHACE syndrome, including three with structural arterial anomalies of the subclavian arteries, three with aortic arch anomalies (right sided or narrowed arch), two with congenital heart disease (atrial septal defect and ventricular septal defect; tetralogy of Fallot), one with a retinal scar, and one with a sternal defect (scar). Two of five had small facial hemangiomas of the lower lip, but none had large segmental hemangiomas of the face. Three of five would have met diagnostic criteria for PHACE but lacked a facial hemangioma of 5 cm in diameter or greater. Patients with segmental arm and thorax hemangiomas may have associated structural abnormalities with overlapping features of PHACE, suggesting that a similar syndrome can occur in this clinical setting.

    Infantile hepatic hemangioma is the third most frequent liver tumor in children and the most common below 6 months of age. Therapeutic options depend on clinical manifestations and should be tailored on an individual patient basis. We present the case of a 4 year old boy with neonatal diagnosis of large vascularized liver tumor with imagiological criteria of infantile hepatic hemangioma. We highlight the occurrence of heart failure and Kasabach-Merrit syndrome (thrombocytopenia, anemia) that have spontaneously regressed. During follow up, sequential imaging (ultrasound with Doppler, magnetic resonance imaging, dynamic contrast enhancement computed tomography) confirmed the hypothesis of IHH, allowing vascular mapping of the lesion. From the first year on, we observed a favorable course with progressive tumor regression. In the present case, a conservative approach has been maintained, but the best therapeutic option remains unclear. We highlight the specific features of this case, discussing the most cost-effective approach.

    Pulmonary sclerosing hemangioma (PSH) is an uncommon benign tumor that presents as a solitary asymptomatic and slow-growing nodule. It occurs in both young and old persons; peak incidence is in the fifth decade. Both sexes are affected by this tumor, but women more frequently than men. On histological examination, PSH shows prominent sclerotization and vascularization of the tissue. Recent studies conclude that PSH derives from type II pneumocytes, but the potential for progression and histogenesis remains controversial. We report a case of pulmonary sclerosing hemangioma in a 61-year-old woman with a neoplastic node 1 cm in diameter. The karyotype was 46,XX,t(8;18),der(14;15),+14 in all the cells analyzed. PTEN (10q23) and IgH (14q32) probes were analyzed in interphase nuclei and paraffin-embedded tissues of tumor cells. These chromosome abnormalities could provide information about the relationship of genetic changes to the biological properties of sclerosing hemangioma tumors.

    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.

    Hemangiomas are common benign vascular tumors of infancy characterized by a proliferative growth phase followed by very slow inevitable regression (involutive phase) between one to ten years of age, about 60% to 70% of the lesions are found in the head and neck region. There are many treatment modalities reported in the literature for head and neck hemangiomas, including wait and see policy, drug therapy, sclerotherapy (steroids, bleomycin), cryotherapy, isotope radiotherapy, laser therapy, and surgical therapy. There still exist many controversies over the optimal treatment options for individual patient. Based on our clinical experience on 250 cases and literature review, a rational treatment regime for head and neck hemangioma was proposed in this study: (1) As it is not possible to predict, whether a hemangioma will remain small and unproblematic or grow into a very large lesion, early therapy is the only way out of this dilemma. A white or pink macule, a port-wine stain-like lesion initially appearing in the children can be effectively and easily removed by laser, thus preventing a growth in the size in the early stage. (2) The term of "wait and see" should be substituted by "close observation", and this approach should only be reserved for hemangiomas which are without visible growth or in the involutive phase. (3) Systematic drug therapy (steroids, interferon alpha-2a ) should be considered for large hemangioma, multiple hemangiomas, life-threatening hemangiomas and hemangiomas with complications such as ulceration, infection, bleeding, dysfunction, etc. Congestive heart failure, consumptive coagulopathy, and thrombocytopenia are also urgent indications for the institution of corticoid therapy. (4) Growing hemangioma can be treated effectively by systematic drug therapy, sclerotherapy, laser therapy or combined therapy. The argon laser (514 nm in wavelength, 0.5 mm in depth) is useful in the treatment of superficial telangiectasias and small, flat cutaneous

    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.

    A 78-year-old euthyroid patient presented for evaluation of a symptomatic, slowly growing neck mass. Ultrasound scan revealed a multinodular goiter and a hypoechoic nodule of the right thyroid lobe. Total thyroidectomy was performed and the lesion was completely excised. Definite diagnosis was obtained after histological examination of the surgical specimen. Cavernous hemangiomas of the thyroid gland are infrequent lesions which may escape diagnosis preoperatively. An effort should be made not to rupture these lesions in order to ensure a bloodless procedure.

    Abstract 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

    Abstract Rationale: Lobular capillary hemangioma (LCH) of the tracheobronchial tree is a rare benign tumor, whose characteristics and treatments remain relatively unknown. Patient concerns: A 39-year-old man with hemoptysis caused by neoplasm in the bronchus intermedius was admitted to our hospital. Diagnoses: The patient was diagnosed with LCH. Interventions: The lesions were removed with biopsy forceps, and cryotherapy was performed. Outcomes: After follow up for more than 2 years, no recurrence was found. Lessons: Airway LCH can be treated by excisional biopsy, cryotherapy, APC, laser, radiotherapy, and surgery. Cryotherapy is worthy of recommendation. PMID:27902613

    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

    Over the past decade, the treatment of infantile hemangiomas has undergone dramatic breakthroughs. This review critically evaluates the latest literature that supports the myriad treatment options for infantile hemangiomas. It chronicles the fading role of steroid therapy and evolution of propranolol use as the major treatment modality. Although propranolol is helping this disease become more of a medical disease and less of a surgical dilemma, the report also reveals a continued search to find nonsystemic treatment options. In summary, this is an evidence-based medicine review for the treatment of infantile hemangiomas.

    Cavernous hemangiomas are the most common benign tumors of the liver, which are now seen more often thanks to common use of newer imaging techniques. A review of the literature on cavernous hemangiomas of the liver, including the author's experience with 14 cases, provides data as a touchstone for discussion of the incidence, etiology, symptoms, pathology, diagnosis including ultrasound, radionuclide imaging, computed tomography and angiography, management including resection, hepatic artery ligation, radiation and corticosteroid, and the natural history of these lesions. The author concludes that surgical resection of cavernous hemangiomas should be undertaken with due concern for the relation between the severity of symptoms and the operative risks involved.

    The authors reexamined the files of seven patients dealt with for intramuscular hemangioma of forearm. It concerns five women and two men, between 16 and 39 years old. The average time of consultation was 13 months. The clinical signs were dominated by the development of a generally painless soft mass over the anterior compartment of the forearm and/or the elbow. Two patients presented nervous lesions signs of the ulnar or median nerves. The feeder pedicle was the ulnar artery in five cases and radial artery in two cases. The excision was incomplete in two cases because of the invasion of the ulnar nerve by the hemangioma. With four years average follow-up, the five patients having undergone a complete excision do not present a recurrence and the hand function is excellent. The authors insist on the interest of a preoperative diagnosis with the IRM, which permits to envisage surgical difficulties due to the proximity of vascular and nervous pedicles.

    Dumbbell-shaped spinal extradural cavernous hemangioma is rare. The differential diagnosis of dumbbell-shaped spinal tumors based on magnetic resonance imaging includes schwannoma and lymphoma. Here, we report a dumbbell-shaped spinal extradural cavernous hemangioma with intrathoracic growth on T2-3 in a 64-year-old man complaining of right side infrascapular area back pain with no neurologic deficit. The cavernous hemangioma was resected through combined video-assisted thoracoscopy and laminectomy without a fusion procedure. The patient had tolerable operative wound pain with no neurologic deficit after surgery. Based on magnetic resonance imaging findings and a review of the literature, we discuss cavernous hemangioma among the differential diagnosis of paravertebral dumbbell-shaped spinal tumors and the importance of complete resection.

    Congenital hemangioma is a benign tumor caused by dysfunction in embryogenesis and vasculogenesis, which progresses during fetal life to manifest as fully developed at birth. Although hemangiomas are the most common tumor of infancy, rapidly involuting congenital hemangioma has not been described in spondylocostal dysostosis. I report the novel association of congenital hemangioma and spondylocostal dysostosis in a Mexican newborn female patient with neural tube defects. Given the embryological relationship between skin and nervous system, I surmise that this association is not coincidental. I also propose that these morphologic alterations be incorporated to the spondylocostal dysostosis phenotype and specifically looked for in other affected children, in order to provide appropriate medical management and genetic counseling.

    Intramedullary masses are a dilemma due to the limited access for a nonsurgical biopsy, thus, accurate imaging characterization is crucial. Magnetic resonance imaging findings of two confirmed canine thoracic intramedullary hemangiomas are described. A capillary hemangioma was of mixed intensity but predominantly T2-hyperintense and mildly T1-hyperintense to spinal cord with strong contrast enhancement. A cavernous hemangioma had a target-like appearance in both T1-weighted (T1w) and T2-weighted (T2w) images. In T2w images there was a small isointense center surrounded by a relatively large hyperintense area. In T1w images, there was a large isointense centre with a relatively small hyperintense periphery. Such characteristics should prioritize hemangioma as a consideration in a progressive myelopathy due to an intramedullary mass.

    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.

    We present two cases of infants with a similar constellation of clinical findings: retro-orbital infantile hemangioma (IH), internal carotid artery (ICA) arteriopathy, and intracranial IH. In both cases, intracranial vascular anomalies and hemangiomas were found incidentally during evaluation of unilateral proptosis. Neither infant had evidence of cutaneous segmental IH of the face or neck, which might have provided a clue to the diagnosis of PHACE syndrome or of intracranial hemangiomas. In one case, intracranial involvement was particularly extensive and function threatening, with mass effect on the brain parenchyma. These cases serve to highlight the fact that clinical findings of proptosis, globe deviation, and strabismus should prompt immediate imaging to confirm the presence of orbital IHs and to exclude other diagnoses. Moreover, based on our cases and the embryologic origin of the orbit as a unique developmental unit, patients with confirmed retro-orbital IHs should undergo evaluation for anomalies associated with PHACE syndrome. Patients with orbital IHs and an additional major criterion for PHACE syndrome should be considered to have definite, and not just possible, PHACE syndrome.

    Thirty-four human "cherry" dermal hemangiomas were studied by electron microscopy, immunohistochemistry, and cell culture to assess the neoplastic nature of these lesions. Electron microscopy of nine hemangiomas revealed a pronounced thickening of the basement membrane (0.6 to 14 micron) in 93% of the total 158 vascular structures examined within the lesions. This increase was caused mainly by multiple layers of basal lamina, which were irregular in outline and frequently associated with pericytes. Basement membrane changes were present both in the periphery of the hemangiomas, as well as in the center of the lesions. Immature vessels could not be identified and mitoses were absent in all endothelial cells. Using an immunohistochemical marker (Ki67) specific for proliferating cells in G2 and S phases, positive staining was not found in the endothelial cells lining the hemangiomatous vessels, whereas basal epidermal keratinocytes in the same preparations and cultured microvascular endothelial cells expressed the antigen. Endothelial cells of nine hemangiomas did not stain with an activation-related antibody (E12) specific for endothelial cells. When endothelial cells from 14 hemangiomas were isolated and cultured under conditions that support the growth of normal human skin microvascular endothelial cells, the cells of hemangiomatous origin failed to grow. We conclude that the adult hemangiomas may not be true neoplasms, but a tissue overgrowth composed of mature vessels resembling dermal venules, lined by endothelial cells with virtually no turnover.

    Infantile hemangiomas are tumors commonly seen in children. Few authors have reported infantile hemangiomas affecting the CNS, and there are no prior reports detailing spontaneous resolution of a histologically proven juvenile hemangioma within a dorsal root ganglion. The authors report the case of a newborn boy with a large cutaneous hemangioma in the midline of his back. Spinal MR images were obtained to rule out associated spinal cord tethering, and an intradural spinal lesion was unexpectedly discovered. Biopsy revealed an intradural infantile hemangioma within the dorsal root ganglion, and, based on this diagnosis, no resection was performed. Sixteen months following the biopsy, the cutaneous hemangioma had become involuted and the intradural hemangioma had completely resolved. The behavior of the intradural component in this case follows the natural history of many cutaneous infantile hemangiomas.

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.

    Cavernous hemangiomas of the liver are sufficiently common that they will often be incidentally discovered during hepatic imaging by ultrasound, computed tomography, or radiocolloid scintigraphy. The differentiation of these benign tumors from primary or metastatic hepatic malignancy is mandatory, but often it is not possible on the study in which the lesion was originally detected. There are several routes by which to arrive at the correct diagnosis, but the optimum study or sequence of studies may elude the physician caring for the patient. Knowledge of the imaging options, and the strengths and weaknesses of each of these options, will facilitate a rapid diagnosis and ensure proper treatment, with maximum patient safety and minimum expenditure of resources. This article examines these radiological options.

    Vascular malformations and hemangiomas are common in children, but gastric hemangioma is extremely rare with less than 15 reported cases in the pediatric age group. Gastric hemangioma accounts for only 0.05% of all gastrointestinal neoplasms, and intra-abdominal hemangiomas are rarely found outside of the liver. We present a unique case of gastric hemangioma, and multiple hemangiomas were detected in a single scan by 99mTc-labeled RBC blood pool imaging. This case also depicts the incremental role of SPECT/CT over planar acquisition for detecting multiple hemangiomas, especially for those lesions located adjacent to physiological blood pool activity.

    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

    Intraosseous hemangiomas are uncommon intrabony lesions, representing approximately 0.5 to 1% of all intraosseous tumors. Their description varies from "benign vasoformative neoplasms" to true hamartomatous proliferations of endothelial cells forming a vascular network with intermixed fibrous connective tissue stroma. These commonly present as a firm, painless swelling. Intraosseous hemangiomas present more commonly in females than in males and most likely occur in the fourth decade of life. The most common etiology of intraosseous hemangioma is believed to be prior trauma to the area. They have a tendency to bleed briskly upon removal or biopsy, making preoperative detection of the vascular nature of the lesion of significant importance. There are four variants: (1) capillary type, (2) cavernous type, (3) mixed variant, and (4) scirrhous type. Generally most common in the vertebral skeleton, they can also present in the calvarium and facial bones. In the head, the most common site is the parietal bone, followed by the mandible, and then malar and zygomatic regions. Intraosseous hemangiomas of the zygoma are rare entities with the first case reported in 1950 by Schoenfield. In this article, we review 49 case reports of intraosseous hemangioma of the zygoma, and also present a new case treated with excision followed by polyether-ether ketone implant placement for primary reconstruction.

    The purpose of this research was to evaluate the immunohistochemical expression of the vascular endothelial growth factor (VEGF-C1) and measuring the angiogenic activity by the staining for von Willebrand factor (vWF) and CD31 in oral pyogenic granulomas and hemangiomas. The results showed that there was no statistically significant difference in the angiogenesis index between the lesions evaluated. The average microvessel density determined for MVC (microvessel count) using CD31 was 60.64 for hemangiomas and 59.64 for pyogenic granulomas, while angiogenic index determined using vWF was 64.24 and 62.20 in these lesions. The results showed that the cells highlighted by staining for vWF were more uniform than in those stained for CD31. There was no statistically significant difference between the lesions for the number of cells highlighted by staining for VEGF-C1. However, the mean number of cells highlighted in pyogenic granuloma specimens was higher (153.23) when compared to oral hemangioma specimens (115.17). The VEGF-positive cells were endothelial cells and fibroblasts in hemangiomas and macrophages and fibroblasts in pyogenic granulomas. These results effort the role of the angiogenic factors in the etiopathogenesis of the hemangiomas and pyogenic granulomas, however, it showed that microvessel quantification is not useful in the differential diagnosis of these lesions.

    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.

    Lower gastrointestinal hemorrhage accounts for approximately 20% of gastrointestinal hemorrhage. The most common causes of lower gastrointestinal hemorrhage in adults are diverticular disease, inflammatory bowel disease, benign anorectal diseases, intestinal neoplasias, coagulopathies and arterio-venous malformations. Hemangiomas of gastrointestinal tract are rare. Mesenteric hemangiomas are also extremely rare. We present a 25-year-old female who was admitted to the emergency room with recurrent lower gastrointestinal bleeding. An intraluminal bleeding mass inside the small intestinal segment was detected during explorative laparotomy as the cause of the recurrent lower gastrointestinal bleeding. After partial resection of small bowel segment, the histopathologic examination revealed a cavernous hemagioma of mesenteric origin. Although rare, gastrointestinal hemangioma should be thought in differential diagnosis as a cause of recurrent lower gastrointestinal bleeding. PMID:19178725

    The CO2 laser has been used by our group as a secure and efficient tool for the treatment of symptomatic oral cavity hemangiomas which can be responsible for disturbance for swallowing, phonation and in hygienic, besides discomfort and bleeding to patients. During the last four years, twelve patients with symptomatic oral cavity hemangioma were treated at the Laser Unit of our University. The treatment consisted in the application of CO2 laser at medium to low intensity according to characteristics and location of the lesions. For hemangiomas located at sites of easy surgical access such as anterior 1/3 of the tongue, lips, bucal vestibule we use 10 to 37 J/mm2 over the surface of the lesion. When the hemangioma was located at difficult surgical access sites, such as, tonsils, posterior 1/3 of tongue, or at pharyngeal wall we used 3.0 to 4.0 J/mm2 encircling the whole hemangioma. This causes reduction in the size of the lesion throughout sclerosis of nutrition vessels. After this initial procedure we applied 0.8 to 1.0 J/mm2 over the whole extent of the lesion. For both procedures we observed no significant bleeding or inflammatory reaction. The patients referred minimal post-operative discomfort with good cicatricial evolution. The evident reduction in the vascularization and size could be confirmed by photographic documentation. The good results described above, with disappearance of symptoms lead to the conclusion that CO2 laser is an efficient and secure method of treatment for symptomatic hemangioma of the oral cavity.

    Giant hepatic hemangioma is a benign liver condition that may be treated using surgery. We studied the digital subtraction angiographic (DSA) characteristics of giant hepatic hemangioma, and the effectiveness of transcatheter arterial embolization (TAE) alone for its treatment. This was a retrospective study of 27 patients diagnosed with giant hepatic hemangioma and treated with TAE alone (using lipiodol mixed with pingyangmycin) at the Division of Hepatobiliary and Pancreatic Surgery, First Affiliated Hospital, Zhejiang University, between January 2010 and March 2013. The feeding arteries were identified using DSA. All patients were followed up for between three weeks and 12 months. Changes in tumor diameter and symptoms were observed. The 27 patients included had giant hepatic hemangiomas ranging from 5.3 to 24.5 cm (mean, 11.24±5.08 cm) in the right (n = 13), left (n = 1) or both (n = 13) lobes. Preoperative hepatic angiography showed multiple abnormal vascular lakes in the early phase, known as the “early leaving but late returning, hanging nut on a twig” sign. On the day after TAE, hepatic transaminase levels were increased (ALT: 22.69±17.95 to 94.88±210.32 U/L; ALT: 24.00±12.37 to 99.70±211.54 U/L; both P<0.05), but not total bilirubin. Six patients complained of abdominal pain, and 12 experienced transient fever. In the months after TAE, tumor size decreased (baseline: 11.24±5.08; 3 months: 8.95±4.33; 6 months: 7.60±3.90 cm; P<0.05), and the patients’ condition improved. These results indicated that TAE was effective and safe for treating giant hepatic hemangioma. TAE may be a useful alternative to surgery for the treatment of hepatic hemangioma. PMID:26287964

    There is no definitive conclusion regarding the optimal timing for terminating propranolol treatment for infantile hemangioma (IH). A total of 149 patients who underwent detailed color Doppler ultrasound examination were included in this study. The characteristics and propranolol treatment of all patients were summarized and analyzed. Patients were divided into two groups according to the lesion regression rate. Among the 149 patients, 38 were assigned to the complete regression group, and 111 were assigned to the partial regression group. The age at which propranolol treatment started, duration of follow-up after treatment discontinuation and rate of adverse events were not significantly different between the two groups. The duration of oral propranolol treatment was shorter in the complete regression group. The age at which propranolol was terminated was younger in the complete regression group, and this group had a lower recurrence rate. Propranolol is safe and effective for the treatment of IHs that require intervention, but it should be stopped at an appropriate time, which is determined primarily by the lesion regression rate after propranolol treatment. Ultrasound is helpful in determining when to stop propranolol for IH.

    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.

    Abstract Introduction: Intramuscular hemangioma (IMH) is a rare congenital soft tissue tumor. Here, we report a case of IMH patient who had undergone several surgeries and other treatments that were all ineffective before he visited us. Clinical Findings: This IMH patient was a 16-yearold male who was born with a tumor of unknown size in his right hand and forearm. On physical examination, the tumor and skin flap complex was seen with a size of 14 cm_12 cm in his right hand, and the multiple postoperative scars were shown on his right hand and forearm. The patient was not able to raise his right shoulder, and the ranges of motion of his right elbow, wrist, and finger were almost zero degrees. Interventions: Considering that the tumor had been surgically excised for several times and the multiple recurrences had affected adversely his daily life, an amputation of his right hand, forearm, and the part of his right arm was performed. Diagnoses: The pathological examination confirmed the diagnosis of IMH. Outcomes: After the amputation surgery, the patient gained a functional recovery and the tumor did not recur during the 2 years after the surgery. Conclusion: A treatment of choice should be personalized according to an IMH patient's overall situation. For an IMH patient like our case with a history of multiple tumor recurrences, we suggest that an amputation surgery should be performed as early as possible to avoid the repeated, but ineffective surgical excisions and the unnecessary sufferings.

    The surgical removal of retrobulbar hemangioma is described in a mature fantail goldfish (Carassius auratus) with a 6-week history of a swollen right eye. The fish was anesthetized using alfaxalnone at a concentration in the water of 5 mg/L to facilitate fine-needle aspiration and surgical removal of the eye. The fish was treated with enrofloxacin 5 mg intraperitoneally and recovered with major buoyancy deficits that corrected 20 minutes after treatment with methadone at a dose of 0.4 mg intramuscularly. Histologic examination of the excised tissue demonstrated that the tumor was a compact hemangioma.

    Primary intraosseous cavernous hemangiomas (PICHs) are rare tumors, and there are no previous reports of cases with a tumor at the anterior clinoid process. We report a case of a PICH at the anterior clinoid process in a 66-year-old female presenting with headaches and visual impairment. CT and MR imaging showed a mass in the anterior clinoid process. The lesion showed hyperintensity on T1- and T2-weighted imaging, and gadolinium was homogenously enhanced. The lesion was removed surgically, and histologically confirmed as a cavernous hemangioma. Preoperative examinations could not provide a definitive diagnosis. A brief clinical and radiological review of the literature is presented.

    Three cases of symptomatic cavernous hemangioma of the liver are reported. All three patients have normal angiograms. A review of the literature shows that the diagnosis of hemangioma may be made noninvasively with a high degree of accuracy. Technetium Tc 99m-labeled red blood cell scanning is very specific, while dynamic computed tomography may be more sensitive for small lesions. A combination of the two modalities makes the diagnosis in greater than 90% of cases. Magnetic resonance imaging is also sensitive and specific. Angiography, as shown in these cases, may not only be questionably indicated, but may be misleading. The treatment for symptomatic lesions is resection, and secondary alternatives are discussed.

    Infantile hemangioma (IH) is the most common benign vascular tumour affecting children. Most infantile hemangiomas are self-limiting, but some require specific treatment. Propranolol has been proposed for the treatment of infantile hemangiomas. The aim of this study is to explore the mechanism of action of propranolol for the treatment of infantile hemangiomas and to demonstrate its safety and efficacy through a review of the literature. The non cardioselective bêta-blocker propranolol has been used in a pediatric setting for 40 years and, since 2008, has a new indication. A clearly significant improvement has been observed in the condition of children with complicated IH (10%) treated with propranolol. This new indication has been widely described in the international literature. Various explanations have been put forward for the mechanism of action including a vasoconstrictor, antiangiogenic and apoptotic effect of propranolol on the different cells making up an IH. Overall tolerance is good and the efficacy markedly superior to that of any other treatments used for this purpose. In conclusion, with its good tolerance profile and superior efficacy versus all the other available therapies, propranolol can be considered to be a first-line treatment for complicated IH.

    Intraosseous vascular lesions are rare conditions. They are most commonly seen in the vertebral column and skull; nevertheless, the mandible is a quite rare location. In this report, we present a case of intraosseous cavernous hemangioma in the mandible and discuss the clinical and radiological features. A 28-year-old male patient attended to our clinic with a complaint of painless swelling of mandible. Clinical evaluation revealed a bone-hard, smooth-surfaced, immobile mass in the left mandibular lingual area. The patient was evaluated with panoramic and occlusal radiography and computed tomography. The lesion surgically excised and pathological examination revealed an intraosseous cavernous hemangioma. Follow-up imaging 1 year later with cone beam computed tomography revealed recurrence of the lesion. The conclusion of this paper; when a bone hard, well-shaped mass was seen in the mandible, the possibility of intraosseous hemangioma must be remembered and before surgical procedure detailed radiographic evaluation should be performed.

    Cellular hemangioma is a subtype of hemangioma that is associated with cellular immaturity and the potential for recurrence. Intracranial location of these lesions is extremely rare, and definitive treatment often requires radical neurosurgical resection. The authors report a case of a 12-year-old boy with a subtemporal cellular hemangioma. He underwent gross-total resection of the tumor, but within 1.5 months the tumor recurred, necessitating a second resection. Because of its proximity to vascular structures, only subtotal resection was possible. Repeat MRI 1 month after the second surgery showed significant tumor recurrence. Given the tumor's demonstrated capacity for recurrence and its proximity to the vein of Labbé and sigmoid sinus, further resection was not indicated. In an effort to limit radiation therapy for this young patient, treatment with bevacizumab and temozolomide was chosen and achieved a complete response that has proven durable for 36 months after cessation of therapy. This is the first report of the successful use of chemotherapy to treat an intracranial hemangioma, a rare condition with limited therapeutic options.

    Intramedullary spinal cord cavernous hemangiomas (angiomas) are occult vascular malformations characterized by rare lesions consisting of closely packed capillary-like vessels. In general, patients with this disease become symptomatic because of hemorrhage leads to progressive neurological deficits. Therefore, surgical tumor resection should be considered for symptomatic patients should be considered a surgical tumor resection.

    Pulmonary sclerosing hemangioma is an uncommon benign tumor of the lung; however, on rare occasions it can arise from the pulmonary hilar region. Herein, we report a 53-year-old female patient who presented with a round opacity in the right upper lung field on a radiograph. Chest computed tomography scanning revealed a 3.1 cm mass in the right pulmonary hilum. Thoracoscopic tumor excision was subsequently performed. On pathohistologic study, the tumor was well defined and composed of round stromal cells and surface cells arranged in a papillary, sclerotic, solid, and hemorrhagic pattern. In immunochemical study, the round cells were positive for thyroid transcription factor-1 (TTF-1) and epithelial membrane antigen (EMA) and negative for cytokeratin. The surface cells were positive for TTF-1, EMA, and cytokeratin. Therefore, a final diagnosis of sclerosing hemangioma was confirmed. In conclusion, pulmonary sclerosing hemangioma is uncommon and rare in the pulmonary hilar region. CT scanning is useful to determine its benignity, although imaging features are not specific for a definite differential diagnosis from other pulmonary tumors. Therefore, tissue diagnosis is usually necessary, and pulmonary sclerosing hemangioma should be listed in the differential diagnoses of pulmonary hilar tumors. PMID:27761142

    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.

    Abstract Background: Umbilical cord hemangioma is very rare and may not be detected prenatally. However, it should be considered in differential diagnosis with other umbilical masses because it can cause significant morbidity. Methods: We report the case of a newborn referred with suspected omphalitis and umbilical hernia. Results: Physical examination showed an irreducible umbilical tumor, the size of olive, with dubious secretion. The initial suspected diagnosis was urachal or omphalomesenteric duct remnants. Abdominal ultrasound and magnetic resonance imaging showed an umbilical and a mesenteric mass. Tumor markers were negative. A definitive diagnosis of umbilical cord and intestinal hemangioma was established after surgical excision and histologic examination of the umbilical mass. Propranolol was prescribed due to the extent of the intestinal lesion. Conclusion: This report highlights the diagnostic challenges of hemangiomas in unusual locations. Apart from the rarity of these tumors, few tests are available to guide diagnosis, and surgery and histologic examination are generally required for a definitive diagnosis. Finally, it is essential to rule out associated malformations and hemangiomas in other locations. PMID:27759656

    We present a young asymptomatic woman with splenomegaly and a large isolated splenic mass demonstrated by ultrasonography, /sup 99m/Tc sulfur colloid, and gallium scintigraphy studies. Computerized tomography (CT) and three-phase 99mTc-labeled red blood cell imaging suggested a malignant lesion. Repeated sonographically guided fine needle aspiration (FNA) obtained only blood, suggesting the possible vascular nature of the tumor. Splenectomy established the diagnosis of splenic hemangioma (SH) with marked sclerotic changes. We conclude from this case that (1) the sclerotic and cystic changes in the SH and the abdominal lymphadenopathy could explain why the three-phase red blood cell and CT scanning, respectively, suggested that the lesion was malignant rather than benign; (2) guided FNA of a splenic mass suspected to be hemangioma may be an additional safe and useful diagnostic procedure. Multiple aspirations yielding blood alone suggest hemangioma and may prevent an unnecessary operation. To the best of our knowledge, this is the first reported case in the literature of FNA of splenic hemangioma.

    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.

    The incidence of vertebral hemangiomas as the most common benign spinal neoplasms has been differently reported from 10 to 27% based on autopsy series, plain X-rays and MRI reviews. In this study, we reviewed consecutive 782 standard spinal MRI with axial and sagital T1 weighted and T2 weighted images looking for hemangiomas. In this study, the incidence of hemangioma was 26.9%, more common in females (30%) than males (23%), in older age group and in lumbar spine. Most hemangiomas (65%) were less than 10 mm in diameter. Multiple hemangiomas were seen in 33% of cases. The results of this study are similar to another Mediterranean study reported based on MRI findings, but differ from other reports using X-ray or autopsy as diagnostic tool, suggesting the influence of either the race or the sensitivity of the diagnostic tool on the incidence of vertebral hemangioma.

    Vertebral body hemangiomas are benign lesions and account for 4% of all spinal tumors. The most common histological type is cavernous hemangioma. These tumors generally locate in the vertebral body as a solitary lesion. Multiple lesions are seen in approximately 25-30% of vertebral hemangiomas. Mostly they are asymptomatic and incidentally found with radiological studies. Symptomatic vertebral hemangiomas are rare and represent < 1% of all hemangiomas; however, if untreated, they may cause local or radicular pain and neurological deficits ranging from myeloradiculopathy to paralysis. In this case we aim to present preoperative and postoperative Computed Tomography findings of a cavernous hemangioma that caused sudden motor deficit and was localised to the thoracic vertebra corpus and posterior elements.

    Hemangioma of infancy is the most common neoplasm of childhood. While hemangiomas are classic examples of angiogenesis, the angiogenic factors responsible for hemangiomas are not fully understood. Previously, we demonstrated that malignant endothelial tumors arise in the setting of autocrine loops involving vascular endothelial growth factor (VEGF) and its major mitogenic receptor vascular endothelial growth factor receptor 2. Hemangiomas of infancy differ from malignant endothelial tumors in that they usually regress, or can be induced to regress by pharmacologic means, suggesting that angiogenesis in hemangiomas differs fundamentally from that of malignant endothelial tumors. Here, we demonstrate constitutive activation of the endothelial tie-2 receptor in human hemangioma of infancy and, using a murine model of hemangioma, bEnd.3 cells; we show that bEnd.3 hemangiomas produce both angiopoietin-2 (ang-2) and its receptor, tie-2, in vivo. We also demonstrate that inhibition of tie-2 signaling with a soluble tie-2 receptor decreases bEnd.3 hemangioma growth in vivo. The efficacy of tie-2 blockade suggests that either tie-2 activation or ang-2 may be required for in vivo growth. To address this issue, we used tie-2-deficient bEnd.3 hemangioma cells, which, surprisingly, were fully proficient in in vivo growth. Previous studies from our laboratory and others have implicated reactive oxygen-generating nox enzymes in the angiogenic switch, so we examined the effect of nox inhibitors on ang-2 production in vitro and on bEnd.3 tumor growth in vivo. We then inhibited ang-2 production pharmacologically using novel inhibitors of nox enzymes and found that this treatment nearly abolished bEnd.3 hemangioma growth in vivo. Signal-transduction blockade targeting ang-2 production may be useful in the treatment of human hemangiomas in vivo.

    Capillary hemangiomas are frequently encountered superficially in the cutaneous, subcutaneous, or mucosal tissues during the childhood and early adulthood, but the occurrence of spinal intradural capillary hemangioma is relatively rare. Herein, we report a case with capillary hemangioma of the thoracic spine. MR and PET/CT features of this lesion are presented, and awareness of this entity may help differentiate it from other spinal intradural tumors.

    Hemangiomas are customarily described as low-grade vascular tumors most often located in the head and neck, but on rare occasions occurring in the intradural space of the spine. The different subtypes of hemangiomas can be distinguished histologically as capillary, cavernous, or mixed types. We describe a rare case of a mixed capillary-cavernous extramedullary intradural hemangioma of the thoracic spinal cord, mimicking meningioma radiologically.

    Tracheal hemangioma is a rare benign vascular tumor in adults. We reported a case of massive hemoptysis caused by a cavernous hemangioma in a 75-year-old man. 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

    Retroperitoneal hemangiomas are very rare. This paper presents the case of a 71-year-old female patient with giant cavernous hemangioma of the retroperitoneum who underwent surgical treatment for abdominal pain and left lower limb edema. Interventional staged treatment with percutaneous transcatheter arterial embolization prior to surgery was considered. Radical resection of the tumor was performed, which caused the symptoms to abate. Additionally a literature review of cases involving cavernous hemangioma in the retroperitoneal space is presented. No description of retroperitoneal cavernous hemangioma originating from the bowel was found in the analyzed reports. PMID:28096841

    Anastomosing hemangioma of the kidney is a very rare neoplasm, currently 19 cases have been reported in the literature. First described in 2009, histopathologically anastomosing hemangioma is similar to aggressive angiosarcoma. No long-term follow-up data of anastomosing hemangioma have been described yet. Here, we present the case of a healthy 56-year-old man diagnosed in 2002 with a 7 × 5-cm anastomosing hemangioma mimicking an aggressive renal angiosarcoma. The patient underwent nephrectomy and has been followed up disease free for 13 years.

    Capillary hemangiomas of the tracheobronchial tree are extremely rare in adults, with hemoptysis being one of the most serious forms of presentation. An operation has been the treatment of choice, although it does involve high rates of morbidity and mortality, especially in emergency situations such as massive hemoptysis, which has led to the search for other therapeutic alternatives. There is no experience with embolization by interventional radiology when the hemoptysis is tracheal in origin, caused partly because the infrequency of this pathology; however, the foundations for it have been laid with the development of embolization for bronchopulmonary pathology. We report a case of a tracheal capillary hemangioma in a 66-year-old woman diagnosed with idiopathic thrombopenic purpura, which began as a massive hemoptysis and was treated successfully with embolization by interventional radiology. There has been no recurrence of the bleeding after 1 year's follow-up, and the patient's control fibrobronchoscopy is normal.

    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.

    Congenital vascular tumors of the skin have been described in people and a few animals, but unlike infantile hemangiomas in children, spontaneous regression has not been described in animals. A 2-day-old male Belgian Blue cross calf was presented for multiple congenital cutaneous masses that were soft, alopecic, and hyperemic; the calf had no other apparent abnormalities. Two weeks later, one mass had regressed. Surgical excision of one of the remaining masses was performed; histopathologic and immunohistochemical findings were considered diagnostic for epithelioid hemangioma. Eight months following initial presentation, all the masses had regressed spontaneously. This constitutes the first account in the veterinary literature of spontaneous regression in a congenital vascular tumor.

    Capillary hemangiomas are benign vascular neoplasms rarely involving the spinal cord, where their usual location is extramedullary. A 59-year-old man presented with a 7-month history of progressive numbness which began in the left lower extremity and progressed across the lower back, right flank, trunk and into the right lower extremity with associated pressure and pain in his lower back. On magnetic resonance imaging, there was an avidly-enhancing thoracic intradural lesion that contained an extramedullary intradural component posteriorly, with an apparent intramedullary component anteriorly. Laminectomy of T7 - 8 was performed, and intradural exploration revealed a highly vascular-appearing tumor below the arachnoid, which was not completely dissected because it was densely adherent to the spinal cord. The pathological diagnosis was lobular capillary hemangioma with extra- and intramedullary components. We suggest this lesion should be considered in the differential diagnosis of spinal cord tumors with an intramedullary component.

    Purpose: In this study we report a percutaneous technique to achieve sclerosis of vertebral hemangioma and decompression of the spinal cord and nerve roots. Methods: Under CT guidance the affected vertebral body is punctured by a biopsy needle and sclerosant is injected directly into the tumor. In the case of large paravertebral extension, additional injection is given in the paravertebral soft tissue component to induce shrinkage of the whole tumor mass and release of the compressed spinal cord. Results: Using this technique we treated five patients in whom vertebral hemangioma gave rise to neurologic symptoms.In three patients, sclerotherapy was the only treatment given. In the other two patients, sclerotherapy was preceded by transcatheter embolization. Neither decompressive surgery, radiation therapy nor stabilization was required with this technique. Conclusion: Our experience with CT-guided intraosseous sclerotherapy has proved highly satisfactory.

    Objective To compare computed tomography (CT) and magnetic resonance imaging (MRI) findings between two histological types of nasal hemangiomas (cavernous hemangioma and capillary or lobular capillary hemangioma). Materials and Methods CT (n = 20; six pre-contrast; 20 post-enhancement) and MRI (n = 7) images from 23 patients (16 men and seven women; mean age, 43 years; range, 13-73 years) with a pathologically diagnosed nasal cavity hemangioma (17 capillary and lobular capillary hemangiomas and six cavernous hemangiomas) were reviewed, focusing on lesion location, size, origin, contour, enhancement pattern, attenuation or signal intensity (SI), and bony changes. Results The 17 capillary and lobular hemangiomas averaged 13 mm (range, 4-37 mm) in size, and most (n = 13) were round. Fourteen capillary hemangiomas had marked or moderate early phase enhancement on CT, which dissipated during the delayed phase. Four capillary hemangiomas on MRI showed marked enhancement. Bony changes were usually not seen on CT or MRI (seen on five cases, 29.4%). Half of the lesions (2/4) had low SI on T1-weighted MRI images and heterogeneously high SI with signal voids on T2-weighted images. The six cavernous hemangiomas were larger than the capillary type (mean, 20.5 mm; range, 10-39 mm) and most had lobulating contours (n = 4), with characteristic enhancement patterns (three centripetal and three multifocal nodular), bony remodeling (n = 4, 66.7%), and mild to moderate heterogeneous enhancement during the early and delayed phases. Conclusion CT and MRI findings are different between the two histological types of nasal hemangiomas, particularly in the enhancement pattern and size, which can assist in preoperative diagnosis and planning of surgical tumor excision.

    Vascular anomalies are a heterogeneous group of congenital blood vessel disorders more typically referred to as birthmarks. Subcategorized into vascular tumors and malformations, each anomaly is characterized by specific morphology, pathophysiology, clinical behavior, and management approach. Hemangiomas are the most common vascular tumor. Lymphatic, capillary, venous, and arteriovenous malformations make up the majority of vascular malformations. This paper reviews current theory and practice in the etiology, diagnosis, and treatment of these more common vascular anomalies. PMID:22611412

    Background: Cavernomas are benign lesions that most commonly occur intra-parenchymally, but occasionally they have been described as arising from the dura mater. Extra-axial cavernous angiomas (or hemangiomas) account for 0.4–2% of all intracranial vascular malformations, and they usually occur in the middle cranial fossa, associated with the cavernous sinus. Other possible localizations (e.g. tentorium, convexity, anterior cranial fossa, cerebellopontine angle, Meckel's cave, sella turcica and internal auditory meatus) are rare, and they account only for 0.2–0.5%. Case Description: We report a case of a 30-year-old female presenting with a 2 years history of headache unresponsive to drug therapy. The magnetic resonance imaging showed a dural-based lesion in the left frontal region; the lesion size was: 1.5 cm × 3.5 cm. The appearance suggested a convexity meningioma. A left frontal craniotomy was performed, and the histopathological diagnosis deposed for a cavernous hemangioma of the dura mater. The follow-up at 1-year was good without any neurologic deficit. Conclusions: Dural-based cavernous hemangiomas of the convexity are uncommon lesions. Up to now, only 13 cases have been described in the literature. The authors have discussed clinical aspects, radiological features, surgical treatment, and operative findings. PMID:26421218

    Infantile hemangiomas (IHs) are the most common benign tumor of infancy, characterized by a natural history of early proliferation in the first months of life to eventual involution during childhood, often with residual fibrofatty tissue. Once involution has been achieved, IHs do not typically recur. We present two cases of exogenous growth hormone therapy resulting in the recurrence of IHs in late childhood, supported by radiological, immunohistochemical, in vitro, and in vivo evidence.

    Objectives The aim of this study was to evaluate the technical and clinical outcomes of using laparoscopic radiofrequency (RF) ablation for treating large subcapsular hepatic hemangiomas. Methods We retrospectively reviewed our sequential experience of treating 124 large subcapsular hepatic hemangiomas in 121 patients with laparoscopic RF ablation. Results The mean diameter of the 124 hemangiomas was 9.1 ± 3.2 cm (5.0–16.0 cm). RF ablation was performed successfully in all patients. There were 55 complications related to the ablation in 26 patients, including 5 of 69 (7.3%) patients with hemangioma <10 cm and 21 of 52 (40.4%) patients with hemangiomas ≥10 cm (P < 0.001). No injuries to abdominal viscera occurred in all the 121 patients. According to the Dindo–Clavien classification, all the complications were minor in 26 patients (Grade I). Out of 124 hepatic hemangiomas, 118 (95.2%) were completely ablated, including 70 of 72 (97.2%) lesions < 10 cm and 48 of 52 (92.3%) lesions ≥ 10 cm (P = 0.236). Conclusion Laparoscopic RF ablation therapy is a safe, feasible and effective procedure for large subcapsular hepatic hemangiomas, even in the hepatic hemangiomas ≥ 10 cm. Its use avoids thermal injury to the abdominal viscera. PMID:26901132

    Propranolol was first used in 2008 to treat hemangioma; its efficacy and safety have since changed the classical treatment indications. Infantile hepatic hemangioma presents as a spectrum of clinical conditions varying from simple asymptomatic lesions to lethal complications. Tufted hemangioma and Kaposiform hemangioendothelioma are congenital vascular tumors that lead to Kasabach-Merritt syndrome. Hemangiomas, like pure arteriovenous malformations, can cause hyperdynamic heart failure, and diffuse nodular-type hemangiomas can present with hypothyroidism. Respiratory problems and hepatic failure can be associated with diffuse nodular-type liver hemangiomas. There is a spectrum of approaches to management, varying from "watchful waiting" to liver transplant. In the age of propranolol, there has been a prominent change in the infantile hepatic hemangioma treatment algorithm. Our suggestion is early treatment with 3 mg/kg/day propranolol plus 1.0 to1.5 mg/kg/day prednisolone in all patients. This protocol is the most effective strategy for type 3 infantile hepatic hemangioma. Approximately one-third of patients with abdominal compartment syndrome in the era before propranolol treatment required liver transplant; this new treatment obviates transplant for many of these patients.

    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

    Vertebral hemangiomas are benign lesions and are often asymptomatic. Most vertebral hemangiomas that cause cord compression and neurological symptoms are located in the thoracic spine and involve a single vertebra. The authors report the rare case of lumbar hemangiomas in a 60-year-old woman presenting with severe back pain and rapidly progressive neurological signs attributable to 2 noncontiguous lesions. After embolization of the feeding arteries, no improvement was noted. Thus, the authors performed open surgery using a combination of posterior decompression, intraoperative kyphoplasty, and segmental fixation. The patient experienced relief from back and leg pain immediately after surgery. At 3 months postoperatively, her symptoms and neurological deficits had improved completely. To the authors' knowledge, this is the first description of 2 noncontiguous extensive lumbar hemangiomas presenting with neurological symptoms managed by such combined treatment. The combined management seems to be an effective method for treating symptomatic vertebral hemangiomas.

    Three-phase 99mTc red blood cell scintigraphy is an established technique for distinguishing hemangiomas from other focal liver lesions. The most widely recognized feature is the perfusion to blood-pool mismatch characterized by decreased or normal arterial perfusion, with lesion activity which progressively increases over 1-2 hr. Although increased arterial vascularity of hemangiomas has been described, such cases either involved small portions of the lesion only or occurred in lesions not conclusively proven to be hemangiomas. We report a case of an angiography proven hemangioma with increased arterial vascularity involving a significant portion of the lesion as well as intense early blood-pool activity similar to that seen on delayed imaging. This case emphasizes the diverse appearance of hepatic hemangiomas using 99mTc blood cell scintigraphy.

    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 procedure

    In previous studies, the expression and the role of proangiogenic factors in infantile hemangiomas have been well studied. However, the role of angiogenic inhibitors has been revealed rarely. The expression of PEDF, as the strongest and safe endogenous inhibitor, is still unrecognized until the current study. In order to investigate the expression and significance of the pigment epithelium-derived factor (PEDF) in the proliferating and regressing phases of infantile hemangiomas, the expression of PEDF, VEGF, Ki-67, and CD34 protein in hemangioma tissues was examined with immunohistochemical polymer HRP method in 42 cases during the proliferative phase, 40 cases during the regressing phase, and 11 cases of non-involuting congenital hemangiomas (NICHs). Meanwhile, the mRNA expression of these factors was detected with quantitative realtime RT-PCR. We found the protein and mRNA expression of PEDF in regressing phase was significantly higher than those in proliferative phase and NICHs (P < 0.001), while the protein and mRNA expression of VEGF were much lower (P < 0.001). The microvessel density (MVD), Ki-67 changes, and the expression of PEDF and VEGF were found significantly correlated. These results indicated that the reduction of VEGF and increase in PEDF are causative to the evolution of infantile hemangioma. PEDF may play a key role in the spontaneous regression of infantile hemangioma and may become an important potential therapeutic agent for infantile hemangioma.

    The aim of this study was to assess quantitatively the Kupffer-phase enhancement patterns of hepatic hemangiomas in contrast-enhanced ultrasound (CEUS) with Sonazoid. A total of 46 patients with 46 hepatic hemangiomas (17.1 ± 6.2 mm in diameter, 34 typical type and 12 high-flow type) underwent CEUS in the Kupffer phase. The lesion-to-liver contrast ratio in the Kupffer phase was quantitatively assessed for both types of hemangioma. Most of the hepatic hemangiomas, whether or not they were the high-flow type, were iso- to hypo-echoic relative to the surrounding liver parenchyma. The contrast ratio was -5.33 ± 6.70 dB for the high-flow hemangiomas and -4.54 ± 6.28 dB for the typical hemangiomas. There was no significant difference in contrast ratio between the two types of lesions (p = 0.73). All of the hemangiomas, whether of typical or high-flow type, are iso- to hypo-echoic relative to the surrounding liver parenchyma on Kupffer-phase imaging.

    Although cavernous hemangiomas occur frequently in the intracranial structures, they are rare in the spine. Most of spinal hemangiomas are vertebral origin and "pure" epidural hemangiomas not originating from the vertebral bone are very rare. Our spinal hemangioma case is extremely rare because of its "pure" epidural involvement and intralesional hemorrhage. A 64-year-old man presented with progressive paraparesis from two months ago. His motor weakness was rated as grade 4/5 in bilateral lower extremities. He also complained of decreased sensation below the T4 sensory dermatome, which continuously progressed to the higher dermatome level. Magnetic resonance imaging demonstrated thoracic spinal tumor at T3-T4 level. The tumor was located epidural space compressing thoracic spinal cord ventrally. The tumor was not involved with the thoracic vertebral bone. We performed T3-5 laminectomy and removed the tumor completely. The tumor was not infiltrating into intradural space or vertebral bone. The histopathologic study confirmed the epidural tumor as cavernous hemangioma. Postoperatively, his weakness improved gradually. Four months later, his paraparesis recovered completely. Here, we present a case of pure spinal epidural cavernous hemangioma, which has intralesional hemorrhage. We believe cavernous hemangioma should be included in the differential diagnosis of the spinal epidural tumors.

    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.

    Infra-red diode laser with wavelength 1060 nm was used for combined treatment of 163 children aged from 21 days to 13 years with 221 hemangiomas. For interstitial coagulation a power of 1.8-2 W and a power density of 5-90 J/cm3 were used in continuous mode. For distant coagulation pulse mode was applied with pulse/pause duration 30-50/200-250 ms, average power 1.3-2 W, and power density 65-450 J/cm2. 197 (89.1 %) hemangiomas were capillary, 7 (3.2 %) cavernous, and 17 (7.7 %) combined (combination of capillary and cavernous hemangiomas). The area of hemangiomas ranged from 6 mm2 to 48 cm2. For the majority (193, 87.3 %) of hemangiomas one session of photocoagulation was enough to achieve a good cosmetic effect. However, 28 (12.7 %) hemangiomas were treated repeatedly, 11 (5%) of them needed 4-7 sessions. In 8 children with cavernous and combined hemangiomas both distant and interstitial laser coagulation were used. In all, good or excellent results were obtained in 96,3 % of the patients. In 6 (3.7%) patients with extensive combined hematomas the considerable improvement was achieved.

    Cavernous hemangioma is the most common orbital tumor in adult. There is lot of literatures for clinicopathological features of this tumor. These tumors had been studied for the model of angiogenesis in many of the experimental setups. We present a case of 34-year-old male with this tumor in the left eye with computerized tomography evidence. Postsurgical laboratory findings gave interesting evidence of tumor angiogenesis with tumor endothelial cells and sprouting of the small vessels endothelial cells. Podosome rosette could be conceptualized from the characteristic patterns seen in the tumor. PMID:27905347

    A 10-year-old Chinese female diagnosed with an asymptomatic giant cardiac cavernous hemangioma was reported. The patient originally tended to observation because this unusual cardiac tumoral mass was discovered incidentally during routine health examination of transthoracic echocardiography. Over 5 years of follow-up, the mass had enlarged obviously, and the patient visited our outpatient clinic and was prone to excision. Subsequently, a total resection surgery of the tumor was performed, and the tumor was found to be located on the left atrioventricular groove with complete packing membrane. The patient was discharged on postoperative day 4 and remains asymptomatic on last follow-up.

    Combigan (Allergan, Irvine, CA) is an ophthalmic solution that combines 0.2% brimonidine, a selective α-2 adrenergic agonist, with 0.5% timolol, a nonselective β-adrenergic antagonist. It is approved for the reduction of intraocular pressure in patients with glaucoma or ocular hypertension. There have been recent reports of successful treatment of superficial infantile hemangiomas (IHs) using Combigan topically. We report the case of a 2-month-old girl who developed life-threatening brimonidine toxicity requiring intubation and mechanical ventilation secondary to central nervous system depression and apnea after topical application to an ulcerated IH.

    Vertebral hemangiomas (VHs) are common lesions in the adult population. They are usually asymptomatic and found incidentally on radiological imaging. New-onset back pain followed by subacute progression of thoracal myelopathy is the most common presentation in patients with neurological deficit. Differential diagnoses would include metastasis, multiple myeloma, lymphoma, Paget disease, osseous tumors such as Ewing sarcoma or hemangioblastoma and blood dyscrasia. We present a 41 year-old-male patient with thoracal VH causing myelopathy that completely improved after rehabilitation program with embolization and vertebroplasty procedures.

    Hemangioma of the thyroid gland is an extremely rare condition. We report a case of a primary cavernous hemangioma in the left lobe of the thyroid gland in an 84-year-old woman. Ultrasound examination of the lesion showed an inhomogeneous and hypoechoic nodule that was well demarcated from the rest of the left lobe and hypovascular on color Doppler ultrasound. Ultrasound-guided fine-needle aspiration was performed. The cytologic differential diagnosis included an anaplastic carcinoma of the thyroid gland. After hemithyroidectomy, the final diagnosis was a benign hemangioma of the thyroid gland.

    Cavernous hemangiomas are the most common benign tumors of the liver. Although their clinical course is usually uncomplicated, an accurate diagnosis may be important to exclude conditions that need treatment, (or to avoid an unnecessarily risky percutaneous biopsy). Although blood pool scintigraphy using planar gamma camera imaging is a reliable examination for the diagnosis of liver hemangiomas, it may fail to depict small, deeply seated lesions, and hence miss the diagnosis. Two cases are reported in which SPECT demonstrated delayed pooling in small, deep, space-occupying lesions, which were poorly seen on planar images, and therefore made a cavernous hemangioma the most likely diagnosis.

    Propranolol is becoming the treatment of choice for complicated infantile hemangioma. We report here data on peripheral blood flow, O2-saturation, electrocardiographic PR-interval, left ventricular function, blood pressure and heart rate that were assessed before and during treatment for ≥4 weeks with propranolol 2 mg/kg of body weight daily in 67 infants <12 months of age in normal sinus rhythm and with structurally normal hearts. Management with propranolol was well tolerated in all and did not modify peripheral blood flow, O2-saturation, electrocardiographic PR-interval and left ventricular fractional shortening or ejection fraction. Absolute blood pressure levels were similar without and with propranolol. However, age-adjusted centile levels for both systolic and diastolic levels were significantly lower while on propranolol. The heart rate was significantly lower both when expressed as absolute value and when expressed as age-adjusted centile on treatment with propranolol. In conclusion, propranolol 2 mg/kg of body weight daily causes a statistically though not clinically relevant decrease in blood pressure and heart rate in cardially healthy infants affected by infantile hemangioma. Temporary discontinuation during acute febrile illnesses and during diarrheal diseases should be considered to prevent excessive hypotension.

    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.

    Hemangiomas are benign tumors originating in the vascular tissues of skin, mucosa, muscles, glands, and bones. Although these tumors are common lesions of the head and neck, they rarely occur in the nasal cavity and paranasal sinuses. Cavernous haemangioma of the lateral wall of the nasopharynx has not previously been reported. We examined the clinical, radiological and therapeutic management of cavernous haemangioma of nasopharynx starting from a clinical case of a 26-year-old woman with a history of recurrent and conspicuous epistaxis and left-sided nasal associated severe obstruction. Nasopharynx examination, by flexible endoscopy, showed a cystic mass borne by the left side wall of the nasopharynx, in contact with the soft palate, covered by intact and regular mucosa. Contrast-enhanced computed tomography (CT) scan, confirmed these findings and showed contextual lamellar calcifications and inhomogeneous enhancement. The nasal endoscopic approach (FESS), under general anesthesia, allowed removal of the mass, without complications, after careful hemostasis of arterial branches. It was possible to establish the precise site of origin of the tumor only during the surgical procedure. Histopathological study showed mucosa with extensive vascular proliferation, with framework of lacunar/cavernous haemangioma, also present at lamellar bone tissue level. An unusual site and an unspecific clinical appearance can make diagnosis and treatment of a cavernous hemangioma of the nasopharynx difficult. The nasal endoscopic technique proved to be reliable in terms of adequate exposure and visualization of the lesion, control of bleeding, and complete removal of the mass. PMID:28352748

    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.

    Vertebral hemangiomas are the most common tumours of the vertebral column. Generally, these tumours are asymptomatic but some patients complain of back pain and develop neurologic symptoms due to extraosseous extension. Vertebral hemangiomas can extend extradurally causing neurological impairment as a result of compression of the spinal cord and nerve roots. Vertebral hemangiomas may be multiple and detectable as a component of the Klippel-Trenaunay-Weber syndrome. Although this syndrome consists of deep venous thrombosis, lymphatic anomalies, cutaneous capillary malformations, and hypertrophy of soft tissue and bone on extremities, its clinical presentation may be very variable. We present a unique case of vertebral hemangioma causing spinal cord compression due to the extradural extension that also had deep venous thrombosis, hematuria, hypophyseal cyst and ventricle asymmetry, diagnosed as the Klippel-Trenaunay-Weber syndrome.

    AIM: To compare safety and therapeutic efficacy of laparoscopic radiofrequency (RF) ablation vs computed tomography (CT)-guided RF ablation for large hepatic hemangiomas abutting the diaphragm. METHODS: We retrospectively reviewed our sequential experience of treating 51 large hepatic hemangiomas abutting the diaphragm in 51 patients by CT-guided or laparoscopic RF ablation due to either the presence of symptoms and/or the enlargement of hemangioma. Altogether, 24 hemangiomas were ablated via a CT-guided percutaneous approach (CT-guided ablation group), and 27 hemangiomas were treated via a laparoscopic approach (laparoscopic ablation group). RESULTS: The mean diameter of the 51 hemangiomas was 9.6 ± 1.8 cm (range, 6.0-12.0 cm). There was no difference in the diameter of hemangiomas between the two groups (P > 0.05). RF ablation was performed successfully in all patients. There was no difference in ablation times between groups (P > 0.05). There were 23 thoracic complications in 17 patients: 15 (62.5%, 15/24) in the CT-guided ablation group and 2 (7.4%, 2/27) in the laparoscopic ablation group (P < 0.05). According to the Dindo-Clavien classification, two complications (pleural effusion and diaphragmatic rupture grade III) were major in two patients. All others were minor (grade I). Both major complications occurred in the CT-guided ablation group. The minor complications were treated successfully with conservative measures, and the two major complications underwent treatment by chest tube drainage and thoracoscopic surgery, respectively. Complete ablation was achieved in 91.7% (22/24) and 96.3% (26/27) in the CT-guided and the laparoscopic ablation groups, respectively (P > 0.05). CONCLUSION: Laparoscopic RF ablation therapy should be used as the first-line treatment option for large hepatic hemangiomas abutting the diaphragm. It avoids thermal injury to the diaphragm and reduces thoracic complications. PMID:26019459

    The case of a Japanese woman with glomeruloid hemangioma, an initial marker for POEMS syndrome, is reported. Her cutaneous lesions were multiple and consisted of glomeruloid hemangiomas, cherry-type capillary hemangiomas, and a mixture of both. The specimens of glomeruloid hemangiomas were studied by paraffin section immunohistochemistry with a large panel of antibodies and electron microscopy, respectively. The lesions, whose size ranged from minute foci to large nodules, were composed of anastomosing vascular channels resembling renal glomeruli and had irregular lumina, often featuring capillaries and sinusoid-like spaces. The vascular channels were lined by a single layer of endothelial cells, which showed two types of cells. The capillary-type endothelium possessed large vesicular nuclei with open chromatin and large amount of cytoplasm. The sinusoidal endothelium possessed small basal nuclei with dense chromatin as well as scant amount of cytoplasm. The former cells had a characteristic CD31+/CD34+/UEA I+/CD68- phenotype. Some of these cells ultrastructurally showed intracytoplasmic lumen formation. The latter cells had a characteristic CD31+/CD34-/UEA I-/CD68+ phenotype. The present study shows that glomeruloid hemangioma has unique morphologic and immunologic features that differ from the traditional hemangiomas as well as littoral cell angioma of the spleen.

    Hepatic metastases of neuroendocrine tumors are known to mimic hemangiomas on nonenhanced SE MR sequences. The usefulness of MR examination with gadolinium injection to identify lesions was prospectively evaluated. Nine patients with multiple liver metastases of gastrinomas were compared with six patients showing multiple liver hemangiomas. Patients underwent unenhanced T2-weighted SE, T1-weighted SE, and FLASH sequences, followed by enhanced sequential FLASH sequences and a 5 min delayed T1-weighted SE sequence. On T2-weighted SE sequence, all hemangiomas displayed the same typical morphology as a sharply defined, homogeneous, high signal intensity lesion, but this pattern was also observed for some or all of the lesions in seven of nine patients with gastrinoma metastases. Dynamic FLASH sequences were accurate for lesions larger than 2 cm, hemangiomas displaying a nodular peripheral enhancement with centripetal filling in, and metastases displaying either an initial homogeneous or a regular peripheral enhancement. Precise assessment of lesions smaller than 2 cm remained equivocal. Delayed T1-weighted SE sequence (performed at least 5 min after Gd-chelate injection) was the most accurate technique to identify metastases by showing hypo-or isointensity signal, whereas all hemangiomas were hyperintense. Postcontrast delayed T1-weighted sequence is the primary technique to differentiate equivocal cases of hemangiomas from metastases of gastrinoma. 25 refs., 3 figs., 2 tabs.

    Spinal hemangiomas can be categorized into three different groups based on location. Vertebral body (VB) hemangiomas are frequent incidental findings on magnetic resonance (MR) imaging. There is a subdivision of these with spinal epidural extension that have been reported in the literature. Spinal hemangiomas can also be epidural without VB involvement; these are extremely rare with few reported cases in the thoracic epidural spinal column. The diagnosis and imaging characteristics as well as the surgical tools used in gross-total resection of spinal epidural hemangioma are not well understood. The authors present a detailed characterization of a spinal epidural hemangioma in a 30-year-old woman who presented with complaints of gradual onset of low-back pain that worsened over 1 year. The MR imaging findings indicated a large L2-S1 epidural spinal mass causing thecal sac compression. The patient underwent an L2-S1 laminectomy, and a vascular extradural mass was noted on the posterior aspect of the dura mater. Preoperative spinal angiography as well as intraoperative angiography was performed. Total resection of the tumor was achieved using intraoperative embolization with sodium tetradecyl sulfate and microscopic dissection. The postoperative MR imaging findings and clinical outcome were excellent. The findings and use of sodium tetradecyl sulfate in gross-total resection are discussed. The authors also review treatment modalities and demonstrate the utility and effectiveness of intraoperative sodium tetradecyl sulfate in grosstotal resection of large difficult spinal epidural hemangiomas.

    Cavernous hemangiomas occur frequently in the intracranial structures but they are rare in the spine, with an incidence of 0.22 cases/million/year, which account for 5 - 12% of the spinal vascular lesions, 51% of which are extradural. Most of the epidural hemangiomas are secondary extensions from the vertebral lesions. The spinal cavernous hemangiomas which do not involve the vertebrae are referred to as "pure" types. The pure epidural hemangiomas are rare, which account for only 4% of all the epidural lesions. A case of a Pure spinal epidural cavernous hemangioma in a 50 year old male, with the clinical picture of a slowly progressive compressive myelopathy, has been presented here. The imaging studies showed a well-defined, enhancing epidural lesion at the T7 - T8 level, with dorsal cordedema and myelomalacic changes. A radiological diagnosis of a meningioma was considered. Histopathologically, the lesion was diagnosed as a hemangioma. The patient improved dramatically after the excision of the lesion.

    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.

    We report a rare finding of the coexistence of splenic hemangioma and progressive vascular malformation of the left lower extremity in a child. The lesion on the left calf was described as a vascular malformation in computed tomography and magnetic resonance. At the age of one year, the abdominal Doppler ultrasound was normal. The examination was repeated at the age of six years due to recurrent pain in the left hypochondrium and revealed giant multiple splenic hemangiomas. The girl underwent splenectomy at the age of 14 years. Histological findings demonstrated multiple cavernous hemangiomas. We present our case report regarding the diagnosis of spleen hemangioma and indications for surgical management in children.

    Accuracy and limitations of computed tomography (CT) and sonography in the detection and diagnosis of cavernous hemangioma of the liver were analyzed in 39 cases. In 35 of 38 lesions examined by CT before and after bolus contrast enhancement, findings were dense contrast enhancement spreading in all directions on subsequent scans and/or density (other than capsule or septa) higher than normal hepatic parenchyma after 2 min. Lesions smaller than 1 cm were not detected. Misregistration in sequential scane prevented diagnosis of three of nine lesions smaller than 2 cm. Sonography revealed various patterns of mass, but in the smaller lesions, an extremely hyperechoic pattern was dominant. The contributions of CT and sonography depend on the size of the lesions.

    Summary Infantile hemangiomas are the most common benign tumors of infancy and childhood with a reported incidence of 4% to 10% in infants. We report of a 9 year-old male child with a history of progressively increasing swelling over the right eyebrow region. The lesion was present since childhood; however, it increased in in size over the previous 3–4 months. The CT scan showed scalloping over the right supra-orbital ridge with an intact bone. The child underwent total excision of the lesion. A characteristic scalloping seen on imaging (depression in the outer or inner table of the skull) can help differentiate lesions of extracranial and intracranial origins. PMID:28144385

    Recently, anti-vascular endothelial growth factor (anti-VEGF) agents have been described in the literature as a valid treatment option for symptomatic liver hemangiomas, but only limited evidence supports this notion. The purpose of this study was to elucidate whether or not the administration of anti-VEGF agents can reliably achieve a size reduction in liver hemangiomas. We examined patients with incidental hemangiomas who received anti-angiogenic agents for the treatment of other malignancies. Our study population consisted of 17 colorectal cancer patients and one lung cancer patient carrying 21 hemangiomas who received bevacizumab, and seven renal cell carcinoma patients carrying nine hepatic hemangiomas who received sunitinib. We have measured the liver hemangioma volume on both the pre-treatment and post-treatment computed tomography images and then calculated the volume alteration rates. No statistically significant difference (P = 0.365) in the volume of the liver hemangiomas was observed before (1.1-168.8 cm(3); mean ± SD 19.8 ± 39.7 cm(3)) or after (1.2-163.6 cm(3); 19.3 ± 38.0 cm(3)) bevacizumab treatment. The volume reduction rate ranged from -35.0 to 11.2 % (mean ± SD -1.3 ± 10.8 %). The sunitinib treatment group also showed no statistically significant difference (P = 0.889) in hemangioma volume before (1.2-6.5 cm(3); 3.0 ± 1.8 cm(3)) or after (1.2-6.0 cm(3); 3.0-1.7 cm(3)) treatment. The volume reduction rate ranged from -13.3 to 7.7 % (median: mean ± SD -2.5 ± 6.6 %). We did not observe liver hemangioma shrinkage after bevacizumab or sunitinib treatment. Our data do not support the application of anti-VEGF agents for the treatment of hepatic hemangiomas.

    Aim. Cavernous hemangioma-like Kaposi sarcoma is a rare morphologic type of Kaposi sarcoma. So far there are no cases in the literature defining the histological features of this morphologic spectrum in detail. In this study we presented two classical-type cutaneous Kaposi sarcoma cases with histologic findings resembling cavernous hemangioma in company with clinical and histopathological data. Cases. One hundred and eighty-five classical-type cutaneous Kaposi sarcoma lesions in 79 patients were assessed retrospectively in terms of histopathological features. Findings of two cases showing features of cavernous hemangioma-like Kaposi sarcoma whose clinical data could be accessed were presented in accompany with the literature data. Both cases were detected to have bluish-purple, protruded, irregularly bordered cutaneous lesions. Histopathological examination revealed a lesion formed by cavernous hemangioma-like vascular structures organized in a lobular pattern that became dilated and filled with blood. Typical histological findings of early-stage KS, consisting of mononuclear inflammation, extravasated erythrocytes, and a few immature vascular structures in superficial dermis, were observed. All cases were serologically HIV-1 negative. A positive reaction with HHV-8, CD31, CD34, and D2-40 monoclonal antibodies was identified at both cavernous hemangioma-like areas and in immature vascular structures. Results. Cavernous hemangioma-like Kaposi sarcoma is a rare Kaposi sarcoma variant presenting with diagnostic challenges, that may be confused with hemangioma. As characteristic morphological features may not be observed in every case, it is important for diagnostic purposes to show immunohistochemical HHV-8 positivity in this variant.

    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

    Introduction Hemangiomas are vascular malformations, with slow blood flow, that can occur in any part on the body. They are more common in women and, predominantly, are isolated lesions. The malformation does not spontaneously regress. Subcutaneous hemangioma is a rare variant with an aggressive growth pattern that sometimes recurs after excision. Objective Case report of a subcutaneous cavernous hemangioma in the nasal dorsum treated with endoscopic rhinoplasty. Case Report A 27-year-old woman had a fibroelastic tumor mass in the midline of the nasal dorsum, which was pulsatile; she had obstruction and nasal congestion with associated rhinorrhea, with evolution and worsening over the previous 2 years. Computed tomography showed a tumor demarcated in the nasal dorsum without evidence of intracranial communication. Endoscopic rhinoplasty with septoplasty and associated paranasal sinus sinusectomy was performed without arteriography embolization, sclerotherapy, or laser. Pathologic diagnosis showed cavernous hemangioma. Postoperative follow-up shows no recurrence at 3 years. Discussion This case presented with atypical features, thus making the diagnosis a challenge. Imaging studies were required to confirm the vascular nature of the tumor. Excisional biopsy is the procedure of choice for pathologic examination. Subcutaneous hemangiomas never involute and always need treatment. The surgical approach is exceptional because there was no preoperative diagnosis. In addition, the closed technique provided best aesthetic results in this case. Conclusion Endoscopic rhinoplasty is suitable for nasal dorsum tumor resection and has superior aesthetic result to open techniques. PMID:25992093

    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.

    Hemangiomas, localized tumors of blood vessels, appear in approximately 10-12% of Caucasian infants. These lesions are characterized by a rapid proliferation of capillaries for the first year (proliferating phase), followed by slow, inevitable, regression of the tumor over the ensuing 1-5 yr (involuting phase), and continual improvement until 6-12 yr of age (involuted phase). To delineate the clinically observed growth phases of hemangiomas at a cellular level, we undertook an immunohistochemical analysis using nine independent markers. The proliferating phase was defined by high expression of proliferating cell nuclear antigen, type IV collagenase, and vascular endothelial growth factor. Elevated expression of the tissue inhibitor of metalloproteinase, TIMP 1, an inhibitor of new blood vessel formation, was observed exclusively in the involuting phase. High expression of basic fibroblast growth factor (bFGF) and urokinase was present in the proliferating and involuting phases. There was coexpression of bFGF and endothelial phenotypic markers CD31 and von Willebrand factor in the proliferating phase. These results provide an objective basis for staging hemangiomas and may be used to evaluate pharmacological agents, such as corticosteroids and interferon alfa-2a, which accelerate regression of hemangiomas. By contrast, vascular malformations do not express proliferating cell nuclear antigen, vascular endothelial growth factor, bFGF, type IV collagenase, and urokinase. These data demonstrate immunohistochemical differences between proliferating hemangiomas and vascular malformations which reflect the biological distinctions between these vascular lesions.

    Purpose: To investigate the efficacy and safety of oral propranolol in the management of periorbital infantile hemangioma in four subjects. Materials and Methods: Consecutive patients who presented with periorbital capillary hemangioma with vision-threatening lesions were prospectively enrolled in this study between January 2009 and October 2010. All subjects underwent treatment with 2 mg/kg/day oral propranolol. All subjects underwent ocular, systemic, and radiologic evaluations before treatment and at periodic intervals after starting therapy. Side effects from therapy were also evaluated. Results: Four subjects, between 3 months and 19 months of age, with periorbital hemangioma were enrolled in this study. Two subjects had been previously treated with oral corticosteroids with unsatisfactory response. All subjects had severe ptosis, with the potential for deprivation amblyopia. Three subjects had orbital involvement. After hospital admission, oral propranolol was initiated in all subjects under monitoring by a pediatric cardiologist. Subsequent therapy was performed with periodic out-patient monitoring. All subjects had excellent response to treatment, with regression of periorbital and orbital hemangioma. There were no side effects from therapy. Conclusions: Oral propranolol for periorbital hemangioma was effective in all the four subjects. Oral propranolol may be appropriate for patients who are nonresponsive to intralesional or systemic steroids. In patients with significant orbital involvement and lesions causing vision-threatening complications, oral propranolol can be the primary therapy. PMID:22224018

    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.

    The clinical features, radiologic investigation, and treatment of 20 infants with hepatic hemangiomas are presented. Palpable abdominal mass (n = 18) and cardiac failure (n = 11) were the common presenting features. Nine patients had hyperconsumptive coagulopathy. Seven patients had other hemangiomas. Ultrasound (n = 15) showed the number and distribution of the hemangiomas within the liver. Hypoechoic and hyperechoic elements were present in addition to prominent vascular channels and diminished caliber of the distal aorta. Radionuclide sulfur colloid (n = 12) and labeled red blood cell (n = 7) studies showed the distribution and vascularity of the hemangiomas. Computed tomography (n = 8) revealed central hypointensity with marked peripheral enhancement after contrast. Arteriography now performed only as a prelude to therapeutic embolization demonstrated hypervascularity in each patient, contrast pooling in six and early draining veins in five. Magnetic resonance scanning (n = 3) showed decreased signal intensity on T1 images and high intensity signal on T2. In two patients, there was resolution or improvement of the hemangiomas without therapy. Four patients had surgery (lobectomy (2), trisegmentectomy (1), and surgical evacuation of a central hematoma (1)). Steroids and radiation were given to seven patients, and one patient also required therapeutic embolization. Steroids were the initial therapy in five patients, one of whom later required therapeutic embolization and another cyclophosphamide. Two patients were treated initially with radiation therapy, one of whom also needed emergency hepatic artery ligation. Seventeen of the 20 patients are alive and well from 6 months to 14 years after diagnosis.

    BACKGROUND Despite being the most common tumor of the spine, vertebral hemangioma is rarely symptomatic in adults. In fact, only 0.9-1.2% of all vertebral hemangiomas may be symptomatic. When hemangiomas occur in the thoracic vertebrae, they are more likely to be symptomatic due to the narrow vertebral canal dimensions that mandate more aggressive management prior to the onset of severe neurological sequelae. CASE REPORT An 18-year-old male presented to the emergency room with a one-month history of mild to moderate mid-thoracic back pain, radiating to both lower limbs. It was associated with both lower limb weakness and decreased sensation. There was no history of bowel or bladder incontinence. Neurological examination revealed lower limb weakness with power 3/5, exaggerated deep tendon reflexes, bilateral sustained clonus, impaired sensation below the umbilicus, spasticity, and a positive Babinski sign. A CT scan showed a diffuse body lesion at the 8th thoracic vertebra with coarse trabeculations, corduroy appearance, or jail-bar sign. The patient underwent decompression and fixation. Biopsy of permanent samples showed proliferation of blood vessels with dilated spaces and no malignant cells, consistent with hemangioma. Postoperatively, spasticity improved, and the patient regained normal power. CONCLUSIONS Symptomatic vertebral hemangiomas are rare but should be considered as a differential diagnosis. They can present with severe neurological symptoms. When managed appropriately, patients regain full motor and sensory function. Decompression resulted in quick relief of symptoms, which was followed by an extensive rehabilitation program.

    Vertebral hemangiomas are benign vascular lesions of the vertebral column; only 0.9-1.2% of all vertebral hemangiomas cause spinal cord compression. We report a 34-year-old female who was admitted to the neurosurgery clinic with a history of back pain, poor quality of life and easy fatigability for 1.5 years. Her medical history revealed a fall from a height of 2 meters 1.5 years ago. Neurology examination revealed bilateral hypoesthesia below the T8 level and hyperactive deep tendon reflexes in her left leg. Computed tomography scan of the thoracic spine showed T8 vertebral hemangioma, and magnetic resonance imaging showed a T8 hemangioma compressing the spinal cord. Surgical intervention was planned and T8 total laminectomy was performed. The tumor extending into the anterior spinal cord was resected, and T8 vertebroplasty with short segment posterior stabilization and fusion was performed. We aimed to present a new treatment approach for symptomatic vertebral hemangiomas and reviewed the relevant literature.

    We report the case of 2 infants born with a lumbar dermal sinus tract and an overlying angiomatous skin lesion referred to our pediatric neurosurgery service for evaluation of a tethered cord. Both infants were born with a lumbar dimple and were found to have a large cutaneous hemangioma without neurologic symptoms. An MRI of the lumbar spine revealed an isointense mass in the dorsal epidural at L(4) with an adjacent mass effect and extension into the overlying soft tissues. The spinal cord also appeared to be tethered with a fatty filum terminale. We performed a lumbar laminectomy and laminoplasty to remove the mass and to release the tethered cord. Pathologic examination confirmed the diagnosis of capillary hemangioma. Several case reports describe spinal capillary hemangiomas in adults, but only one found in the literature describes a case in an infant. We provide a review of the literature of spinal capillary hemangiomas and support the practice of evaluating infants with cutaneous lumbosacral hemangiomas for underlying spinal cord abnormalities.

    Introduction Hemangioma is a relatively common benign proliferation of blood vessels that primarily develops during childhood. Two main forms of hemangioma recognized: capillary and cavernous. The capillary form presents as a flat area consisting of numerous small capillaries. Cavernous hemangioma appears as an elevated lesion of a deep red color, and consists of large dilated sinuses filled with blood. The purpose of the study was to report the case of a capillary hemangioma in a patient and to describe the successful treatment of this case. Case presentation The patient was a 19-year-old female who presented herself to the Atatürk University, Faculty of Dentistry, Department of Periodontology, with the complaint of bleeding and slowly enlarging mass on the upper right molar region. The lesion was diagnosed as capillary hemangioma after clinical examination and biopsy. Treatment consisted of scaling, root planning and surgical excision. Four months after surgery healing was occurred and two years later area of the lesion appeared completely normal as clinically. Conclusions The surface is highly keratinized and no further growth was evidenced during the two year of follow-up. Early detection and biopsy is necessary to determine the clinical behavior of the tumor and potential dentoalveolar complications. PMID:20181211

    Primary tracheal tumors are rare in adults, and careful airway management is required during anesthesia for affected patients. We report the case of a patient with tracheal hemangiomas undergoing nontracheal operation. A 61-year-old woman was scheduled for a lung operation. During preoperative examination, hemangiomas were detected on the tracheal mucosa. As she was asymptomatic and the degree of airway stenosis was small, treatment was not required for the hemangiomas, and left upper lobectomy for lung cancer was scheduled. After induction of general anesthesia, a regular tracheal tube was inserted under fiberoptic bronchoscopy, with care taken to prevent damage to the hemangiomas. An endobronchial blocker was inserted for one-lung ventilation. The operation was performed uneventfully, and the tracheal tube was replaced postoperatively with a laryngeal mask airway while the patient was under deep anesthesia and neuromuscular blockade. The mask was removed after confirming lack of bleeding from the hemangiomas. No hypoxia or other complications occurred during or after the operation.

    Capillary hemangiomas, the most common vascular tumors of the sinonasal region, are benign endothelial neoplasms, typically growing in an easily recognized lobular pattern. Some sinonasal capillary hemangiomas may show atypical features, such as high cellularity or mitotic activity, and represent more challenging diagnoses. Over the past several years we have seen in consultation a number of examples of sinonasal capillary hemangiomas displaying very striking stromal myxoid change and hyalinization, features that have received scant attention in the past. Available slides from 16 sinonasal capillary hemangiomas previously coded as showing such changes were retrieved from our archives. Submitting diagnoses included "query angiofibroma, rule out malignancy" (N=4), "vascular polyp, rule out malignancy" (N=3), "query malignant vascular tumor" (N=4), "sinonasal hemangiopericytoma" (N=1), and "benign vascular tumor" (N=1). Available radiographic studies often showed worrisome features. Grossly, the tumors ranged from 1.1 to 6.0 cm and appeared as ulcerated, vascular-appearing polyps. Microscopically, the tumors showed striking stromal myxoid change and/or hyalinization, which largely obscured the underlying lobular capillary arrangement. Within this myxohyaline matrix, a florid capillary proliferation was present, frequently with nonatypical mitotic activity. In some instances a branching, "hemangiopericytoma-like" vascular pattern was present in areas. The overall cellularity was low to moderate, and endothelial atypia or hyperchromatism was absent. Ulceration and thrombosis were frequently present. Immunostains to CD31, CD34, and SMA highlighted areas of lobular growth pattern inapparent on the routinely stained slides. Four tested cases were negative for androgen receptors and β-catenin. Follow-up from 12 patients revealed no local recurrences or metastases. Awareness of that sinonasal capillary hemangioma may show these unusual stromal changes, and the use of

    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.

    Propranolol, as a non-selective blocker of the β-adrenergic receptor (AR), is utilised as the first-line treatment for infantile hemangiomas. However, the underlying mechanism remains poorly understood. The present study was designed to investigate the molecular basis of propranolol on the regression of infantile hemangiomas using a proliferating infantile hemangioma-derived endothelial cell line. In infantile hemangioma patients, we found that propranolol significantly decreased the expression levels of the hypoxia inducible factor (HIF)-1α in serum and urine, as well as in hemangioma tissues. In vitro analysis revealed that propranolol reduces the expression of HIF-1α in hemangioma cells in a dose- and time-dependent manner, mainly by acting on β2-AR. Interestingly, it was observed that overexpression of HIF-1α apparently abrogated the inhibitory effects of propranolol on vascular endothelial growth factor (VEGF) expression and cell growth. Our data further demonstrated that propranolol inhibited the signal transducer and activator of transcription 3 (STAT3), a critical oncogenic signaling molecule, and the anti-apoptotic protein Bcl-2. Additionally, overexpression of HIF-1α significantly reversed the inhibitory effects of propranolol on STAT3 signaling. In a mouse xenograft hemangioma model, overexpression of HIF-1α significantly attenuated the therapeutic effects of propranolol and inhibited propranolol-induced hemangioma cell apoptosis. Moreover, the protein levels of VEGF, phosphorylated STAT3, total STAT3 and Bcl-2 were significantly upregulated by HIF-1α overexpression in propranolol-treated nude mice bearing hemangiomas. Collectively, our data provide evidence that propranolol may regress infantile hemangiomas by suppressing VEGF and STAT3 signaling pathways in an HIF-1α-dependent manner.

    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.

    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

    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.

    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

  2. Sinusoidal hemangioma of the breast: diagnostic evaluation management and literature review

    2017-01-01

    Vascular tumors of the breast are rare and may pose a diagnostic challenge. Breast hemangioma is a very rare benign vascular neoplasm accounting for 0.4% of all breast tumors. It is most commonly detected as an incidental microscopic finding in biopsy specimens obtained for unrelated reasons. We describe here a very rare case of a sinusoidal breast hemangioma in a postmenopausal patient who presented with a palpable breast mass. A complete surgical resection was performed because the tumor exhibited atypical imaging features. We conclude that although in carefully selected cases of breast hemangioma a conservative management with follow up imaging is a reasonable option, in cases with atypical imaging or pathological characteristics a complete surgical resection of the vascular tumor is mandatory in order to exclude the possibility of an underlying angiosarcoma.

    This study investigated factors associated with social isolation in parents of children with hemangiomas. Eighty-one parents completed questionnaires assessing their emotional distress, social isolation, and coping styles. To explore the relationships between these variables, a path analysis was used to test a model in which clinical characteristics of hemangiomas and parents' coping strategies do not have direct effects on their social isolation but indirect effects via their emotional distress. Bootstrapping was used to assess indirect effects. Time since onset and lesional complications had positive direct effects on parents' social isolation. Lesional visibility and emotion-focused coping had negative indirect effects on parents' social isolation via their emotional distress, while problem-focused coping showed a positive indirect effect. These findings may have implications for clinicians managing parents of children with hemangiomas.

    A study was performed to evaluate and compare the sensitivity of magnetic resonance imaging (MRI) and radionuclide blood-pool scanning in the detection of hepatic hemangiomas. All patients had known hemangiomas which were first detected on either ultrasound or computed tomography. Sixteen patients with a total of 23 lesions were investigated. Eleven patients had both MRI and blood-pool scans performed. In the group studied by both modalities, 18 lesions were detected ranging in size from 1 to 11 cm. All lesions were detected by both techniques. However, two of the 18 lesions had an atypical appearance on MRI. Our experience to date indicates that the anatomic location and specific diagnosis of hemangiomas can be made with a high degree of certainty when both MRI and blood-pool scanning techniques are utilized.

    We describe a rare case of vertebra (intraosseous) hemangioma with bilateral and symmetrical epidural extension causing cord compression in a 24-year-old woman. The epidural component was isointense to cord on both T1 and T2 sequences, and enhanced markedly and homogenously following gadolinium administration. The gradual in onset and progressive nature with the typical enhancing pattern lead the neurosurgeon to the more common diagnosis of spinal meningioma. Epidural extension of vertebral hemangiomas causing cord compression is rarely reported. Review of literatures reveal that cases that have been reported are of unilateral extension into epidural space and of cavernous type. This is the first case report of capillary vertebral (intraossous) hemangioma with bilateral extension through both intervetebral foramen into the epidural space causing myelopathy.

    Infantile hemangioma (IH) is the most common tumor of infancy. Its cellular origin and biological signals for uncontrolled growth are poorly understood, and specific pharmacological treatment is unavailable. To understand the process of hemangioma-genesis we characterized the progenitor hemangioma-derived stem cell (HemSC) and its lineage and non-lineage derivatives. For this purpose we performed a high-throughput (HT) phenotypic and gene expression analysis of HemSCs, and analyzed HemSC-derived tumorspheres. We found that IH is characterized by high expression of genes involved in vasculogenesis, angiogenesis, tumorigenesis and associated signaling pathways. These results show that IH derives from a dysregulated stem cell that remains in an immature, arrested stage of development. The potential biomarkers we identified can afford the development of diagnostic tools and precision-medicine therapies to “rewire” or redirect cellular transitions at an early stage, such as signaling pathways or immune response modifiers.

    Hepatic cavernous hemangiomas are benign tumors of the liver that are often an incidental finding. They are usually asymptomatic but may cause symptoms when traumatized, may bleed spontaneously, or may produce pain by virtue of their large size and mass effect. A retrospective analysis of the clinical presentation, liver function tests, and diagnostic imaging procedures in 20 patients with hepatic hemangiomas is presented and the literature is reviewed. The 20 patients had 27 mass lesions as seen on liver scintigraphy, computed tomography, or sonography. Technetium-99m-labeled red blood cell flow studies and blood pool scintigrams showed delayed filling of the mass lesions, diagnostic of hemangiomas. This finding was not encountered in any other type of lesion. A new diagnostic algorithm is proposed in which flood-flow and blood-pool scintigraphy play a more prominent role in the diagnostic workup.

    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

    Patient: Male, 18 Final Diagnosis: Hemangioma Symptoms: Pain • weaknes of lower limbs Medication: — Clinical Procedure: Decompression and fixation Specialty: Neurosurgery Objective: Unusual clinical course Background: Despite being the most common tumor of the spine, vertebral hemangioma is rarely symptomatic in adults. In fact, only 0.9–1.2% of all vertebral hemangiomas may be symptomatic. When hemangiomas occur in the thoracic vertebrae, they are more likely to be symptomatic due to the narrow vertebral canal dimensions that mandate more aggressive management prior to the onset of severe neurological sequelae. Case Report: An 18-year-old male presented to the emergency room with a one-month history of mild to moderate midthoracic back pain, radiating to both lower limbs. It was associated with both lower limb weakness and decreased sensation. There was no history of bowel or bladder incontinence. Neurological examination revealed lower limb weakness with power 3/5, exaggerated deep tendon reflexes, bilateral sustained clonus, impaired sensation below the umbilicus, spasticity, and a positive Babinski sign. A CT scan showed a diffuse body lesion at the 8th thoracic vertebra with coarse trabeculations, corduroy appearance, or jail-bar sign. The patient underwent decompression and fixation. Biopsy of permanent samples showed proliferation of blood vessels with dilated spaces and no malignant cells, consistent with hemangioma. Postoperatively, spasticity improved, and the patient regained normal power. Conclusions: Symptomatic vertebral hemangiomas are rare but should be considered as a differential diagnosis. They can present with severe neurological symptoms. When managed appropriately, patients regain full motor and sensory function. Decompression resulted in quick relief of symptoms, which was followed by an extensive rehabilitation program. PMID:27795545

    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.

    Cavernous sinus hemangioma (CSH) is a rare extra-axial vascular neoplasm that accounts for 2% to 3% of all cavernous sinus tumors. Their location, propensity for profuse bleeding during surgery, and relationship to complex neurovascular structures are factors which present difficulty in excising these lesions. The authors describe their experience of 22 patients with CSH over 14 years at a tertiary care center. Patients were managed with microsurgical resection using a purely extradural transcavernous approach (13 patients) and with Gamma Knife radiosurgery (GKRS; Elekta AB, Stockholm, Sweden) (nine patients). Retrospective data analysis found headache and visual impairment were the most common presenting complaints, followed by facial hypesthesia and diplopia. All but one patient had complete tumor excision in the surgical series. Transient ophthalmoparesis (complete resolution in 6-8 weeks) was the most common surgical complication. In the GKRS group, marked tumor shrinkage (>50% tumor volume reduction) was achieved in two patients, slight shrinkage in five and no change in two patients, with symptom improvement in the majority of patients. To our knowledge, we describe one of the largest series of CSH managed at a single center. Although microsurgical resection using an extradural transcavernous approach is considered the treatment of choice in CSH and allows complete excision with minimal mortality and long-term morbidity, GKRS is an additional tool for treating residual symptomatic lesions or in patients with associated comorbidities making surgical resection unsuitable.

    Mast cell count (MCC) in 45 dogs with cutaneous hemangioma (HA, n = 12), hemangiosarcoma (HSA, n = 12), mammary adenoma (AD, n = 9) and mammary adenocarcinoma (AC, n = 12) was made using Toluidine blue stained sections. Antibodies against endothelial cell markers, Factor VIII and VEGF were used to visualize and determine the hot spot micro-vessel density (MVD). Total MCC and MCC along the invasive edges were significantly higher (p < 0.001) in canine mammary AC than in AD. The total MCC did not significantly differ (p > 0.05), in HSAs (8.6 +/- 3.3) than in HAs (5.5 +/- 2.8). There is a positive correlation (r = 0.14) between the hot spot MCC and MVD in mammary AC, although not significant (p = 0.3172), indicating that mast cells are associated with angiogenesis in canine mammary AC. This study suggests that mast cells may play an important role in neovascularization of canine cutaneous vascular and mammary neoplasms. Detailed studies encompassing correlation of MCC and MVD with clinical outcomes and prognosis in these neoplasms are recommended.

    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.

    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

    Generalized enchondromatosis is a newly delineated type of enchondromatosis. Radiographically there are multiple enchondromata in almost all metaphyses of the long and short tubular bones and the lesions are in almost the same stage of development with mild platyspondyly and skull deformity. The pelvic changes are characteristic and, together with the metaphyseal changes of the long and short tubular bones, are probably diagnostic of this disorder. The present case demonstrates advanced radiographic features of this disorder associated with unusual soft tissue calcifications and hemangiomas. The presence of hemangiomas in our case as well as three cases in the literature suggests this feature is more than a coincidence.

    A case report is presented of a woman with a tumor mass in the nasopharynx. Early and delayed scintigraphy with Technetium 99m-labeled RBCs showed a large area of increased uptake which was later shown to be a hemangioma by contrast angiography. The perfusion-blood pool mismatch observed in hemangiomas is characteristic of these lesions and has not been described in any other abnormalities. The Tc-RBC using both early and delayed scintigraphy is a simple, noninvasive method for assessing the vascular characteristics of these tumors. (JMT)

Case Report: Here, we present a case of a 55-year-old female with a history of partial nephrectomy due to clear cell renal cell carcinoma three years earlier, who presented with a contralateral anastomosing capillary hemangioma.

It has a sinusoidal growth pattern which resembles splenic parenchyma. It mimics malignant neoplasms, thus, clinical and radiological examination are not enough for accurate diagnosis. In this paper, we discuss the most crucial differential diagnoses and the pitfalls in diagnosing this rare variant of hemangioma. Furthermore, we present a literature review of all cases reported in the English-language literature. PMID:28286335

    The utility of Tc-99m RBC imaging in the diagnosis of hepatic cavernous hemangiomas has been established. Of the 25 patients with various focal hepatic lesions evaluated, 16 were diagnosed as having hemangiomas: eight proven by surgery, two proven by angiography, and six proven by maintaining a stable clinical course ranging from 6 to 12 months with normal follow-up liver function tests. Although fourteen of these were detected by planar imaging, two were detected by SPECT only. Two patients with large hemangiomas had false-negative scans, whereas the remaining seven patients had other liver lesions.

    OBJECTIVE Cavernous sinus hemangiomas (CSHs) are rare vascular tumors. A direct microsurgical approach usually results in massive hemorrhage and incomplete tumor resection. Although stereotactic radiosurgery (SRS) has emerged as a therapeutic alternative to microsurgery, outcome studies are few. Authors of the present study evaluated the role of SRS for CSH. METHODS An international multicenter study was conducted to review outcome data in 31 patients with CSH. Eleven patients had initial microsurgery before SRS, and the other 20 patients (64.5%) underwent Gamma Knife SRS as the primary management for their CSH. Median age at the time of radiosurgery was 47 years, and 77.4% of patients had cranial nerve dysfunction before SRS. Patients received a median tumor margin dose of 12.6 Gy (range 12-19 Gy) at a median isodose of 55%. RESULTS Tumor regression was confirmed by imaging in all 31 patients, and all patients had greater than 50% reduction in tumor volume at 6 months post-SRS. No patient had delayed tumor growth, new cranial neuropathy, visual function deterioration, adverse radiation effects, or hypopituitarism after SRS. Twenty-four patients had presented with cranial nerve disorders before SRS, and 6 (25%) of them had gradual improvement. Four (66.7%) of the 6 patients with orbital symptoms had symptomatic relief at the last follow-up. CONCLUSIONS Stereotactic radiosurgery was effective in reducing the volume of CSH and attaining long-term tumor control in all patients at a median of 40 months. The authors' experience suggests that SRS is a reasonable primary and adjuvant treatment modality for patients in whom a CSH is diagnosed.

    We report three new cases of patients with Sturge-Weber Syndrome and symptomatic retinal detachments from diffuse choroidal hemangiomas successfully treated with photodynamic therapy (PDT) and review medical literature on the available treatment options for choroidal hemangiomas. All patients were treated with a single session of PDT with verteporfin infused at a concentration of 6 mg/m(2) and treated for 83 seconds with 689-nm Zeiss laser that was delivered with total energy level of 50 J/cm(2) with an intensity of 600 mW/cm(2). The exudative retinal detachment (RD) and macular edema completely resolved in all cases by 1-4 months after PDT treatment. Visual acuity improved in all three cases with diminished tumor size in the areas of treatment. One case was followed for 5 months, another for 2 years, and the third case for 6 years, with no recurrence of exudative RD. PDT is an effective treatment option for visual deterioration from exudative retinal detachment in patients with diffuse choroidal hemangiomas.

    A 49-year-old woman developed a dark brown nodular mass in the lower eyelid. The lesion had grown fast for 2 months and then had remained stable in size. Excisional biopsy was performed. Histopathological examination of an excisional biopsy specimen pointed to proliferative vessels lined by increased endothelial cells without nuclear atypism. The nodular mass evaluated as a capillary hemangioma. PMID:25370407

    A 52-year-old man with a 9-year history of hepatic hemangioma was treated with the anti-diabetic drug metformin, resulting in complete remission of the tumor. In 2006, a hemangioma with diameter of 20 × 25 mm was detected incidentally in the liver. The results of imaging studies including ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) were all compatible with that of hepatic hemangioma. The patient consequently underwent imaging annually from 2006 to 2015. The tumor size increased slightly, to 30 × 35 mm in 2012; however, the general tumor characteristics in imaging were not changed. Beginning May 2012, metformin (750 mg/day) was administered because of an increase in blood sugar and hemoglobin A1c levels. After the start of metformin treatment, the tumor size on US gradually decreased. Finally, in October 2015, the tumor was no longer detected. Dynamic CT study also demonstrated markedly reduced tumor size, with a decrease of 2-3 mm in diameter. These results indicate that metformin treatment strongly suppressed cell proliferation in liver hemangioma. The anti-angiogenic effect of metformin was indicated as a possible cause of the reduction in tumor size.

  8. Normalisation of asymmetric astigmatism after intralesional steroid injection for upper eye lid hemangioma in childhood.

    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.

    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.

    This case report presents a 66-year-old woman with multiple vertebral hemangiomas causing spinal cord compression at different levels with a long symptom-free interval between episodes of compression. She presented with back pain and progressive weakness and numbness in her lower limbs for 3 months. Ten years earlier, she had had a symptomatic T4 vertebral hemangioma operated successfully, and had made a full recovery. Magnetic resonance imaging (MRI) of the thoracic and lumbar spine revealed multiple thoracic and lumbar vertebral hemangiomas. Extraosseous extension of a hemangioma at T9 was causing spinal cord compression. Selective embolization was performed preoperatively, and cord decompression was achieved via anterior T9 corpectomy. The patient's neurological status improved rapidly after surgery. After a course of radiotherapy, she was neurologically intact and could walk independently. One year later, MRI showed complete resolution of the cord edema at T9, and showed regression of the high signal intensity that had been observed at unoperated levels. These findings indicated diminished vascularity and reduced aggression of the tumor.

    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.

    Hemangioma is a benign vascular tumor, which may occur in any bone of the body. The most common locations are the spine and craniofacial bone; however, occurrence is extremely rare in the scapula. The current study presented the case of a 58-year-old female, with scapula hemangioma in the left shoulder who presented with joint ache that had lasted for ~1 year. The main clinical manifestations included local tenderness, an osseous lump and limited shoulder movement with a little pain, which was alleviated by rest. Roentgenogram, computed tomography and magnetic resonance imaging of the left acromion revealed a mass along the inner surface of the scapula of the left shoulder with polycystic expansion and bone destruction. The results of computed tomography and magnetic resonance imaging indicated a pure primary tumor and the lesion was subsequently resected. Notably, the postoperative pathological diagnosis was capillary hemangioma. The aim of the present study was to analyze the clinical and imaging features of scapula hemangioma, which must be considered for the differential diagnosis of scapula tumors. In the present case, no recurrence was identified by X-ray examination 1 year after surgery. The long-term efficacy of surgical treatment requires continuous observation of the patient.

    Infantile hemangiomas are the most common vascular tumors in childhood. In view of its proven effectiveness in such cases, propranolol is the drug of choice. We present the case of a male infant who started treatment with propranolol shortly after birth due to heart disease. After 7 months, when the patient had suffered various respiratory exacerbations, this treatment was suspended. One week later, multiple skin lesions (ie, multifocal infantile hemangiomas) began to appear, with no extracutaneous involvement. It was decided to resume treatment with propranolol, although at lower doses than before, and the skin lesions improved rapidly, with some disappearing completely. Treatment was definitively withdrawn at age 16 months, with only slight recurrence of the lesions. The case described is of multifocal infantile hemangiomas without extracutaneous involvement appearing beyond the neonatal period after treatment with propranolol beginning in the first days of life. The details of the case support the hypothesis that this drug is not only therapeutic but also plays a prophylactic role against infantile hemangiomas. In turn, this supports the recent proposal that this drug may be useful in preventing the growth and spread of tumors with high angiogenic potential. It is postulated that the inhibition of β-adrenergic receptors is associated with multiple intracellular processes related to the progression and metastasis of different tumors.

    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

    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.

    Pharmacological therapies for infantile hemangiomas were considered effective only during the proliferative phases. Recently reported beneficial effects of propranolol may extend beyond the proliferative phase of infantile hemangiomas. The purpose of the study was to assess the effect of oral propranolol therapy for infantile hemangiomas beyond the proliferative phase of these lesions. Members of the Society for Pediatric Dermatology were invited to participate in a multicenter retrospective study. Only children with infantile hemangiomas with documented cessation of lesions' growth or those older than 12 months of age were eligible for the study. Clinical and demographic information and digital photographs before, at the start, and following the treatment were collected. Scaled panels of photographs were distributed among preselected experienced pediatric dermatologists. Visual analog scale was used to assess photographs for each case. Paired t-test was used for statistical analyses. Data on 49 eligible patients from eight pediatric dermatology centers was collected. Seven cases were excluded because of insufficient photographic documentation. The age of the patients at the start of propranolol therapy ranged 7 to 120 months (mean 28 mos, median 22 mos). The duration of propranolol therapy ranged 1 to 8 months (mean 3.6 mos). The mean visual analog scale score before the treatment was 6.8 ± 2.15, and mean reduction in the visual analog scale score at the assessment was 2.6 ± 1.74 (p < 0.001). The rate of visual analog scale reduction was 0.4 per month before the start of the therapy, while this rate was accelerated to 0.9 per months following the therapy (p < 0.001). No significant side effects were reported. We conclude that propranolol is effective in infantile hemangiomas, including post-proliferative phase, and should be considered as the first-line therapy in that setting.

    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.

    Cavernous hemangioma is the most common benign tumour of the liver and is found quite commonly during abdominal ultrasonography performed for other diseases. It is often asymptomatic and undergoes enlargement in fewer than 10% of cases. Spontaneous rupture of a giant hepatic hemangioma (diameter > 4 cm) with hemoperitoneum occurs very rarely. Only 32 cases have been reported in a recent review of the medical literature, with an operative mortality of more than 35%. We describe a new case of a giant subcapsular hemangioma localised in hepatic segments II and III in an 84-year-old woman, which ruptured spontaneously into the abdominal cavity and presented with hemoperitoneum and hypovolaemic shock. The hemangioma was diagnosed preoperatively by spiral CAT and treated successfully with emergency hepatic bisegmentectomy.

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. They characterize the coordinate distributions of phase shifts in the points of laser images of histological sections of hemangioma, hemangioma blood smears and blood plasma with vascular system pathologies. The diagnostic criteria of hemangioma nascency are determined.

    During the performance of high-resolution real-time abdominal sonography, small echogenic hepatic masses are frequently discovered. A second imaging test to confirm the suspected diagnosis of hemangioma is often required. Planar labeled red-cell imaging will often not detect hemangiomas smaller than 3 cm. We studied 14 patients with labeled red-cell scintigraphy and single-photon emission CT (SPECT). Six hemangiomas were diagnosed by SPECT that would have been missed by planar imaging alone. All six were smaller than 2.5 cm. With the addition of SPECT, labeled red-cell scintigraphy has specificity and sensitivity that make it at least as reliable as dynamic CT for the noninvasive diagnosis of hepatic cavernous hemangioma.

    Infantile hemangiomas are the most common infantile benign vascular tumor. While most infantile hemangiomas proliferate then involute, some may persist and require treatment for reasons including risk of disfigurement or functional impairment. Treatments currently include observation, pharmacological therapy, laser, cryosurgery, surgery and radiotherapy. Although pharmacological therapy is a well accepted treatment option, limited studies have evaluated the efficacy of different drug therapies. In this study, we compare different pharmacological modalities in the management of infantile hemangiomas. The study included 853 infants with proliferative infantile hemangiomas who were treated with topical timolol, oral propranolol, intralesional pingyangmycin, or intravenous vincristine from 2009 to 2012. Treatment stratification was based on clinical severity of the tumor. Response to the treatment was clinically evaluated and graded as: excellent, good, poor, or no response. Response to pharmacological therapies was excellent in almost all infantile hemangiomas. In addition, patients younger than 8 months responded highly to pharmacological treatment (89.1%), while patients older than 8 months were less responsive to treatment (36.3%). There were no instances of life-threatening complications. Overall, these findings support the efficacy of timolol, propranolol, pingyangmycin and vincristine in the treatment of infantile hemangiomas, especially in the youngest patient cohort (8 months or younger).

    Infantile hemangiomas are characterized by rapid capillary growth during the first year of life followed by involution during early childhood. The natural history of these lesions creates a unique opportunity to study the changes in gene expression that occur in the vessels of these tumors as they proliferate and regress. Here we use laser capture microdissection and genome-wide transcriptional profiling of vessels from proliferating and involuting hemangiomas to identify differentially expressed genes. Relative to normal placental vessels, proliferating hemangiomas were characterized by increased expression of genes involved in endothelial-pericyte interactions, such as angiopoietin-2 (ANGPT2), jagged-1 (JAG1), and notch-4 (NOTCH4), as well as genes involved in neural and vascular patterning, such as neuropilin-2 (NETO2), a plexin domain containing receptor (plexinC1), and an ephrin receptor (EPHB3). Insulin-like growth factor binding protein-3 (IGFBP3) was down-regulated in proliferating hemangiomas. Involuting hemangiomas were characterized by the expression of chronic inflammatory mediators, such as the chemokine, stromal cell-derived factor-1 (SDF-1), and factors that may attenuate the angiogenic response, such as a member of the Down syndrome critical region (DSCR) family. The identification of genes differentially expressed in proliferating and involuting hemangiomas in vivo will contribute to our understanding of this vascular lesion, which remains a leading cause of morbidity in newborn children.

    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.

    Targetoid hemosiderotic hemangioma (THH) or hobnail hemangioma (HH) is a benign vascular lesion that presents with the classical clinical presentation of a ring-shaped tumor having a targetoid appearance, with a central purple-brown papule surrounded by a thin pale area and an ecchymotic ring on the outside. Dermoscopic features and patterns of HH have been documented and have proven to be sufficient to establish a clinical diagnosis in many cases. We present a facial lesion in which both the clinical presentation and dermoscopy were atypical. The presence of arborizing vessels in the dermoscopic pattern, never before described for this lesion, led us to the diagnosis of basocellular carcinoma (BCC). We also report the changes in this pattern experienced over 12 months of progression and their correlation with the histopathologic findings. PMID:28243494

    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

    BACKGROUND Retroperitoneal bleeding as a consequence of non-traumatic kidney or allograft rupture is well known, but there are no reports on hemorrhagia from a native kidney after allogeneic renal transplantation. Therefore, we present the first such case to be published and highlight the possibility of this complication after renal transplantation. CASE REPORT We report the case of a 28-year-old male patient who developed early post-transplant hemorrhagia from a ruptured native kidney. The patient underwent left-sided nephrectomy. Histopathological examination revealed ruptured hemangioma of the patient's native left kidney. The further postoperative period was not complicated. The patient was discharged on the 18th postoperative day, with good transplant function. CONCLUSIONS Transplantologists should be aware of the fact that in patients with uncontrolled blood pressure, native kidney hemangioma may rupture in the early post-transplant period, and it can be a life-threating and difficult to diagnose complication.

    Type and timing of treatment for symptomatic hemangiomas in pregnant females are challenging due to fetus survival and conflicts in neurological recovery. In this article, we report a 40-year-old female patient at pregnancy week 23 with a complicated hemangioma at T1 level. Physical examination revealed an incomplete spastic paraplegia. Patient did not accept any surgery due to child's death risk. Patient was started corticoid treatment and no more weight bearing was allowed. At the 28th week of pregnancy, the patient underwent cesarean section immediately followed by selective arterial embolization, decompression, fixation, and radiotherapy. At two-year follow-up, the patient was pain free, without any signs of local recurrence and with complete neurological recovery. A multidisciplinary approach is mandatory to save the life of the fetus without damaging the spinal cord functions of the mother.

    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.

    Results of application of low invasive laser technology (developed by authors: Proc. 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.

    Infantile hemangiomas (IH) are common tumors for which there is no validated disease-specific instrument to measure the quality of life in infants and their parents/caregivers during the critical first months of life. This study prospectively developed and validated a quality-of-life instrument for patients with IH and their parents/caregivers and correlated demographic and clinical features to the effects on the quality of life. A total of 220 parents/caregivers completed the 35-item Infantile Hemangioma Quality-of-Life (IH-QoL) instrument and provided demographic information. The dimensionality of the items was evaluated using factor analysis, with results suggesting four factors: child physical symptoms, child social interactions, parent emotional functioning, and parent psychosocial functioning. Each factor fit the Rasch measurement model with acceptable fit index (mean square <1.4) and demonstrated excellent internal consistency, with alpha ranging from 0.76 to 0.88. The final instrument consists of four scales with a total of 29 items. Content validity was verified by analyzing parents' responses to an open-ended question. Test-retest reliability at a 48-hour interval was supported by a total IH-QoL intraclass correlation coefficient of 0.84. Certain clinical characteristics of hemangioma, including those located on the head and neck, in the proliferative stage, and requiring treatment, are associated with a greater impact on QoL.

    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.

    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 histologically distinctive cutaneous hemangioma occurring in two patients with biopsy-proven multicentric Castleman's disease associated with POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein, skin changes) syndrome are reported. The lesions were multiple, and appeared as red to purple papules over the trunk and proximal limbs. Microscopically, ecstatic dermal vascular spaces were seen filled with aggregates of capillaries, resulting in structures reminiscent of renal glomeruli. Interspersed between the blood-filled capillary loops were plump "stromal" cells possessing clear vacuoles and periodic acid-schiff-positive eosinophilic globules. These cells had the immunohistochemical profile of endothelial cells (positivity for factor VIII-related antigen, and negativity for leukocyte common antigen, macrophage marker, and muscle-specific actin), and probably represented immature elements that had accumulated immunoglobulins and other proteinaceous material from the circulation. Because vascular lesions may appear before the full-blown POEMS syndrome develops, we suggest careful evaluation and follow-up of all patients presenting with glomeruloid hemangioma or cherry-type capillary hemangioma with focal glomeruloid features for potential development of this syndrome.

    When a cryogen spurt is applied to the skin surface for tens of milliseconds, cooling remains localized in the epidermis, leaving the temperature of deeper hemangioma vessels unchanged. The objective of this study was to compare the efficacy and safety of noncooled laser treatment (NC-LT) vs. cryogen spray cooling plus laser treatment (CSC-LT) for cutaneous hemangiomas in a large series of patients. A retrospective review was conducted of 164 patients treated with the pulsed dye laser (lambda = 585 nm; taurho = 450 microsec) over an 8-year period. Eighty-two patients received NC-LT using light doses of 5.5 to 8 J per square centimeter. Subsequently, 82 patients received CSC-LT using light doses of 9 to 10 J per square centimeter. The primary efficacy measure was quantitative assessment of improvements in lesional volume, texture, and color. Safety was evaluated for each treatment group by monitoring for adverse effects. Based on chi-squared analysis, there were clinical and significant differences in the number of treatments (p = 0.001), and improvement in volume (p = 0.008) and texture (p = 0.001) of the CSC-LT group compared with the NC-LT group. Permanent adverse effects were not observed in either group. In conclusion, CSC permitted the use of higher incident light doses for treatment of cutaneous hemangiomas, resulting in fewer treatments required and better improvement in lesional volume and texture.

    T1-weighted and T2-weighted pulse sequences were employed for MR imaging of hepatic metastatic tumors (98 patients), hemangiomas (24 patients), and cysts (seven patients); a 0.6-T superconducting magnet was used. In a retrospective study, signal intensity and morphology were used to establish criteria for differentiating metastases from hemangiomas and cysts. The signal intensity of the lesion alone failed to be an etiologic discriminator because over 96% of all masses had a signal intensity less than that of liver on T1-weighted sequences, and at least 90% had a signal intensity greater than that of liver on T2-weighted sequences. Morphologic features depicted on T2-weighted images were more specific than those depicted on T1-weighted images in differential diagnosis. Amorphous, target, and halo signs and a change in morphology were present only in metastatic disease, with a frequency of 45%, 27%, 13%, and 12%, respectively. Two other morphologic patterns--doughnut and lightbulb signs--were found to have overlapping causes. Overall, at least one of the specific signs was observed in 92% of patients with metastatic disease. These data suggest that T2-weighted pulse sequences are essential for discriminating between hepatic metastases and hepatic hemangiomas and cysts. MR imaging is a promising technique for distinguishing these lesions.

    Cavernous hemangiomas are one of the most common benign tumors of the orbit in adults. We report a case of a longstanding retrobulbar hemangioma that was removed successfully through a temporal transconjunctival approach combined with lateral canthotomy. A 45-year-old female patient, with a 15-year history of slowly progressive proptosis and decreased visual acuity of the left eye, had a corrected visual acuity of finger count at 50 cm OS, compared with 1.0 OD. Exophthalmometry by the Nagle's method measured 15 mm OD by 26 mm OS. Magnetic resonance imaging (MRI) revealed a well-encapsulated retrobulbar main mass, 2.3 x 3.0 x 3.7 cm in size along with multiple small satellite nodules that were displacing the optic nerve and globe superiorly. The tumors were removed through a superotemporal transconjunctival approach combined with lateral canthotomy. Pathological examination revealed an intraorbital cavernous hemangioma. The patient was free of visible scars, proptosis and any other noticeable complications at her last follow-up, 6 months after surgery.

    Preoperative embolization and excision used to be standard therapy amongst a wide range of other more or less successful methods for the treatment of voluminous hemangiomas. Nowadays a combination of argon, tunable dye, copper vapor and Nd:YAG laser therapy achieves better cosmetic and functional results. Due to its limited penetration depth percutaneous laser therapy can only be utilized for superficial vascular malformations. Interstitial laser therapy, as performed with the Nd:YAG laser, allows treatment of voluminous hemangiomas in their full extent. The localization of these vascular lesions is evaluated by high resolution ultrasound with a new anular array scanner which ensures the precise intraoperative placement of the laser light fiber in the target tissue. Modified new light applicators improve the interstitial thermotherapy of hemangiomas. The tip design of the scattering-dome fiber allows diffuse circumferential irradiation with larger defined coagulation volume and minimized carbonization. Continuous intraoperative sonographic monitoring lowers the risk of damaging adjacent intact anatomical structures, helps to reach all tumor areas an to estimate the effect of the applied laser light caused by changes of sonomorphology. The postoperative outcome is evaluated by B-mode sonography and the new technique of ultrasound color angiography.

    A 14-year-old spayed female domestic short-haired cat was presented for evaluation of a mass in the right eye. Ophthalmic examination revealed a blind right eye and presence of two distinct masses: a pink and a red-to-brown mass, the latter occupying most of the cornea and part of the conjunctiva. Exenteration was performed under general anesthesia, and the ocular tissues were processed routinely for histopathology. Upon microscopic examination, a malignant epithelial neoplasm and a benign vascular neoplasm were present in the cornea. The conjunctiva and the third eyelid were also affected. Upon immunohistochemistry, the epithelial tumor was positive for cytokeratin and negative for vimentin and the endothelial tumor was negative for cytokeratin and positive for vimentin. A diagnosis of squamous cell carcinoma (SCC) and hemangioma was made. The SCC was affecting the cornea, bulbar conjunctiva (lateral and inferior) and the base of the third eyelid, whereas the hemangioma was affecting the cornea and medial limbus. To the authors' knowledge, this is the first report of concomitant SCC and hemangioma affecting the ocular surface in a cat.

    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.

    Thirty-seven patients with 69 suspected hemangiomas found by means of computed tomography (CT) and/or ultrasound were studied with both 0.5-T magnetic resonance (MR) imaging and single photon emission CT (SPECT) with technetium-99m-labeled red blood cells. Using a criterion of perfusion-blood pool mismatch, SPECT readers diagnosed 50 of 64 hemangiomas and all five nonhemangiomas (sensitivity, 78% (95% confidence interval, 0.664 - 0.864); accuracy, 80% (0.69 - 0.877)). Qualitative analysis of lesion signal intensity on T2-weighted spin-echo MR images allowed readers to diagnose 58 of 64 hemangiomas and four of five nonhemangiomas (sensitivity, 91% (0.814 - 0.96); accuracy, 90% (0.807 - 0.951)). Because of the significantly higher cost of MR imaging and its inability to categorically differentiate hemangiomas from hypervascular metastases, the authors consider SPECT to be the method of choice for diagnosing hepatic hemangiomas. MR imaging should be reserved for the diagnosis of lesions smaller than 2.0 cm and for those 2.5 cm and smaller adjacent to the heart or major hepatic vessels; in such cases MR imaging was found superior to SPECT.

    Background Lobular capillary hemangioma is a rare benign tumor, most frequently located in the head or neck region, the nasal cavity being uncommonly affected. Its etiopathogenesis is not fully established, although traumatic and hormonal factors have been implied. Case Description A 50-year-old female patient underwent an uneventful endoscopic transsphenoidal removal of a pituitary cystic macroadenoma at our institution. Nasal packing was used in postoperative hemostasis. Histopathology was compatible with a gonadotrophin-producing adenoma. One month after the surgery, the patient presented with frequent episodes of epistaxis and a progressively growing nasal mass, which was removed endoscopically. Its pathological examination confirmed a lobular capillary hemangioma. Conclusions The authors present a clinical case combining two possible predisposing factors to the development of a nasal lobular capillary hemangioma: local traumatic injury through surgery and postoperative nasal packing and hormonal influence. This lesion is a rare complication of endoscopic transsphenoidal resections of pituitary adenomas.

    Intraosseous hemangioma is a rare bone tumor accounting for 0.7%–1.0% of all bone tumors. In the skull, frontal bone is the commonly involved bone. An 8-year-old female presented to our outpatient department with complaints of pain and swelling over forehead for 4 months. X-ray revealed a lytic expansile lesion involving frontal bone with sunburst pattern of bony spicules radiating to periphery of the lesion. Magnetic resonance imaging revealed the presence of a well-circumscribed lesion with both intra as well as extracranial components. Histopathology revealed a vascular tumor consisting of both small (capillary) and large (cavernous) sized vessels. A diagnosis of mixed type of hemangioma of the frontal bone was given. Recognition of hemangioma on radiology and confirmation by histopathology is essential for proper management as it might be confused clinically with other locally aggressive/malignant lesions.

    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.

    Fourteen patients with hepatic hemangiomas were evaluated by Tc-99m colloid scintigraphy and Tc-99m RBC angiography, including flow studies and early and delayed static studies. On colloid scintigraphy, the liver appeared enlarged, with single or multiple focal defects. During the flow and early static Tc-99m RBC studies, the lesions showed poor perfusion and were filled only partially or not at all. Delayed Tc-99m RBC studies demonstrated the whole extent of the lesion and all the lesions when multiple hemangiomas were present. A flow study showing decreased perfusion and a late blood-pool study showing increased local blood volume appear characteristic of hemangiomas. Liver biopsy should not be attempted in such cases.

    Fourteen patients with hepatic hemangiomas were evaluated by Tc-99m colloid scintigraphy and Tc-99m RBC angiography, including flow studies and early and delayed static studies. On colloid scintigraphy, the liver appeared enlarged, with single or multiple focal defects. During the flow and early static Tc-99m RBC studies, the lesions showed poor perfusion and were filled only partially or not at all. Delayed Tc-99m RBC studies demonstrated the whole extent of the lesion and all the lesions when multiple hemangiomas were present. A flow study showing decreased perfusion and a late blood-pool study showing increased local blood volume appear characteristic of hemangiomas. Liver biopsy should not be attempted in such cases.

    Background Lobular capillary hemangioma is a rare benign tumor, most frequently located in the head or neck region, the nasal cavity being uncommonly affected. Its etiopathogenesis is not fully established, although traumatic and hormonal factors have been implied. Case Description A 50-year-old female patient underwent an uneventful endoscopic transsphenoidal removal of a pituitary cystic macroadenoma at our institution. Nasal packing was used in postoperative hemostasis. Histopathology was compatible with a gonadotrophin-producing adenoma. One month after the surgery, the patient presented with frequent episodes of epistaxis and a progressively growing nasal mass, which was removed endoscopically. Its pathological examination confirmed a lobular capillary hemangioma. Conclusions The authors present a clinical case combining two possible predisposing factors to the development of a nasal lobular capillary hemangioma: local traumatic injury through surgery and postoperative nasal packing and hormonal influence. This lesion is a rare complication of endoscopic transsphenoidal resections of pituitary adenomas. PMID:28326242

    Propranolol, a nonselective blocker of β-adrenergic receptors, has become the first-line treatment for complicated infantile hemangiomas. Therefore, its use in the pediatric population has expanded in recent years. In adults, β-blockers have been reported to be the most common causative agents for drug-induced psoriasis. In infants treated with propranolol for infantile hemangioma, the onset of psoriasiform diaper rash has not yet been reported. Here, to the best of our knowledge, we report the first case of psoriasiform diaper rash possibly induced by oral propranolol in an 18-month-old girl with no family history of psoriasis.

    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.

    The aim was to compare high-resolution computed tomography (HRCT) and thin-section magnetic resonance imaging (MRI) findings of facial nerve hemangioma. The HRCT and MRI characteristics of 17 facial nerve hemangiomas diagnosed between 2006 and 2013 were retrospectively analyzed. All patients included in the study suffered from a space-occupying lesion of soft tissues at the geniculate ganglion fossa. Affected nerve was compared for size and shape with the contralateral unaffected nerve. HRCT showed irregular expansion and broadening of the facial nerve canal, damage of the bone wall and destruction of adjacent bone, with "point"-like or "needle"-like calcifications in 14 cases. The average CT value was 320.9 ± 141.8 Hu. Fourteen patients had a widened labyrinthine segment; 6/17 had a tympanic segment widening; 2/17 had a greater superficial petrosal nerve canal involvement, and 2/17 had an affected internal auditory canal (IAC) segment. On MRI, all lesions were significantly enhanced due to high blood supply. Using 2D FSE T2WI, the lesion detection rate was 82.4 % (14/17). 3D fast imaging employing steady-state acquisition (3D FIESTA) revealed the lesions in all patients. HRCT showed that the average number of involved segments in the facial nerve canal was 2.41, while MRI revealed an average of 2.70 segments (P < 0.05). HRCT and MR findings of facial nerve hemangioma were typical, revealing irregular masses growing along the facial nerve canal, with calcifications and rich blood supply. Thin-section enhanced MRI was more accurate in lesion detection and assessment compared with HRCT.

    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

    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

    Vascular tumors and disorders, like angiomatosis, are rarely described in cetacean species. A retrospective histological study was carried out on lung samples from 35 common dolphins (Delphinus delphis) stranded in the Canary Islands coasts looking for morphological vascular changes and likely related causes. Twenty-five out of thirty-five (71%) common dolphins showed focal or multifocal angiomatosis-like lesions. A high association between this type of vascular proliferation and parasitic infestation was observed. In addition, a single pulmonary cavernous hemangioma not previously reported in common dolphins is presented.

    Epithelioid hemangioma (EH) is an uncommon benign vascular lesion, also known as angioblastic lymphoid (or angiolymphoid) hyperplasia with eosinophilia, characterized by an unclear etiopathogenesis. It usually affects young to middle-aged adults and develops in the head and neck region, as painless cutaneous or subcutaneous reddish papules or nodules. Large vessels involvement is extremely rare, and to date only two cases affecting the brachial artery have been cited in literature.

    This report describes a case of successful percutaneous direct-puncture ethanol embolization, followed by vertebroplasty, of an aggressive vertebral hemangioma (VH) involving two adjacent thoracic vertebral levels. In this case, the 78-year-old male patient presented with a 6-month history of progressive paraparesis due to spinal cord compression by a T8-T9 VH with an extensive epidural component. Follow-up demonstrated epidural component shrinkage with complete regression of symptoms at 3 months. This case suggests that exclusive percutaneous treatment may be considered for symptomatic VH even when two adjacent vertebral levels are affected.

    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. With no objective tool to monitor IH, a handheld wireless device (HWD) that uses diffuse optical spectroscopy has been developed for use in assessment of IH by measurements in absolute oxygenated and deoxygenated hemoglobin concentration as well as scattering in tissue. Reconstructions of these variables can be computed using a multispectral evolution algorithm. We validated the new system by experimental studies using phantom experiments and a clinical study is under way to assess the utility of DOI for IH.

    Background Senile hemangioma, so-called cherry angioma, is known as the most common vascular anomalies specifically seen in the aged skin. The pathogenesis of its abnormal angiogenesis is still unclear. Methodology/Principal Findings In this study, we found that senile hemangioma consisted of clusters of proliferated small vascular channels in upper dermis, indicating that this tumor is categorized as a vascular tumor. We then investigated the mechanism of endothelial proliferation in senile hemangioma, focusing on microRNA (miRNA). miRNA PCR array analysis revealed the mir-424 level in senile hemangioma was lower than in other vascular anomalies. Protein expression of MEK1 and cyclin E1, the predicted target genes of mir-424, was increased in senile hemangioma compared to normal skin or other anomalies, but their mRNA levels were not. The inhibition of mir-424 in normal human dermal microvascular ECs (HDMECs) using specific inhibitor in vitro resulted in the increase of protein expression of MEK1 or cyclin E1, while mRNA levels were not affected by the inhibitor. Specific inhibitor of mir-424 also induced the cell proliferation of HDMECs significantly, while the cell number was decreased by the transfection of siRNA for MEK1 or cyclin E1. Conclusions/Significance Taken together, decreased mir-424 expression and increased levels of MEK1 or cyclin E1 in senile hemangioma may cause abnormal cell proliferation in the tumor. Senile hemangioma may be the good model for cutaneous angiogenesis. Investigation of senile hemangioma and the regulatory mechanisms of angiogenesis by miRNA in the aged skin may lead to new treatments using miRNA by the transfection into senile hemangioma.

    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

    Parkinson's disease (PD) is a severe neurodegenerative disorder caused by progressive loss of dopaminergic neurons in the substantia nigra pars compacta of the midbrain. The molecular mechanism of PD pathogenesis is unclear. Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are a common genetic cause of familial and sporadic PD. However, studies on LRRK2 mutant mice revealed no visible dopaminergic neuronal loss in the midbrain. While surveying a LRRK2 knockout mouse strain, we found that old animals developed age-dependent hepatic vascular growths similar to cavernous hemangiomas. In livers of these hemangioma-positive LRRK2 knockout mice, we detected an increased expression of the HIF-2α protein and significant reactivation of the expression of the HIF-2α target gene erythropoietin (EPO), a finding consistent with a role of the HIF-2α pathway in blood vessel vascularization. We also found that the kidney EPO expression was reduced to 20% of the wild-type level in 18-month-old LRRK2 knockout mice. Unexpectedly, this reduction was restored to wild-type levels when the knockout mice were 22 months to 23 months old, implying a feedback mechanism regulating kidney EPO expression. Our findings reveal a novel function of LRRK2 in regulating EPO expression and imply a potentially novel relationship between PD genes and hematopoiesis. PMID:27872856

    Capillary hemangiomas are benign tumors found in the skin and soft tissues in younger people. They occur in the central nervous system only rarely, and intradural occurrence is extremely rare. We report here a 60-year-old man presenting with thoracic girdle pain and progressive gait disturbance. Magnetic resonance images of the thoracic spine showed a 12 × 8 × 20 mm, well-defined intradural mass at the T2 level, compressing the spinal cord laterally. Relative to the spinal cord, the mass was hypo- to isointense on T1-weighted images and relatively hyperintense on T2-weighted images, with strong enhancement on contrast-enhanced T1-weighted images. The patient underwent T1-2 hemilaminectomy with resection of the intradural extramedullary tumor, which showed characteristics of a capillary hemangioma on histologic examination. The patient's symptoms improved following the surgery and no clinical or radiological evidence of recurrence was noted at the 2-year follow-up. We present this case with a review of the literature, highlighting features for differential diagnosis. PMID:25045565

    Endothelial glucose transporter 1 (GLUT1) is a definitive and diagnostic marker for infantile hemangioma (IH), a vascular tumor of infancy. To date, GLUT1-positive endothelial cells in IH have not been quantified nor directly isolated and studied. We isolated GLUT1-positive and GLUT1-negative endothelial cells from IH specimens and characterized their proliferation, differentiation and response to propranolol, a first-line therapy for IH, and to rapamycin, an mTOR pathway inhibitor used to treat an increasingly wide array of proliferative disorders. Although freshly isolated GLUT1-positive cells, selected using anti-GLUT1 magnetic beads, expressed endothelial markers CD31, VE-Cadherin and VEGFR2, they converted to a mesenchymal phenotype after three weeks in culture. In contrast, GLUT1-negative endothelial cells exhibited a stable endothelial phenotype in vitro. GLUT1-selected cells were clonogenic when plated as single cells and could be induced to re-differentiate into endothelial cells, or into pericyte/smooth muscle cells or into adipocytes, indicating a stem cell-like phenotype. These data demonstrate that, although they appear and function in the tumor as bona fide endothelial cells, the GLUT1-positive endothelial cells display properties of facultative stem cells. Pretreatment with rapamycin for 4 days significantly slowed proliferation of GLUT1-selected cells, whereas propranolol pretreatment had no effect. These results reveal for the first time the facultative nature of GLUT1-positive endothelial cells in infantile hemangioma. PMID:25187207

    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

    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

    An 11-year-old male child presented with a mass on the nasal aspect of the right eye that has been there for the last 2 years. Extraocular movements were decreased in the right eye on levoversion, levoelevation, and levodepression. Local examination revealed a bluish mass with irregular surface and ill-defined margins located in the medial rectus muscle. The mass was 10 × 20 mm in size, firm, nodular, nontender, nonpulsatile, noncompressible, and nonreducible. MRI of the orbit revealed a well-defined mass of approximately 23 × 13 mm along the medial rectus (MR) muscle. It was hyperintense on T2W images with very minimal contrast enhancement. A provisional diagnosis of hemangioma or lymphangioma with intralesional haemorrhage was made. During surgical excision, the mass was found to be encapsulated by MR fibres. The MR fibres were separated, and the mass measuring 20 × 8 × 6.5 mm was removed and sent for histopathology. The histopathological examination revealed an intramuscular cavernous hemangioma.

    Vascular maxillo-facial malformations, common pathologies in children, represent 7% of all benign tumors. They are divided into vascular malformations and hemangiomas. In the 70s-80s radiotherapy was the most applied technique, but because of its misuse or overdose, it could lead to relevant and hard consequences for the impact on the salivar glands, periodontium and growing maxillo-facial nuclei. The authors describe the case of a 38-year-old man, who, during infancy, was submitted to radiotherapy for a hemangioma to his chin and cheek. He was under observation for an agressive periodontitis, followed by a serious facial asimmetry, located in his irradiated side. They describe the therapy and the results obtained, underlying the particular difficulties detected in operating on tissues hardly and often irreversibly injured by radiotherapy. On the basis of this clinical case and of the most up-dated knowledge, therapeutical alternatives such as embolization, cryotherapy, cortisonic systemic and intralesional therapy, the use of interferon gamma 2 and the use of the most recent laser, are analyzed, and advantages and disadvantages and the most appropriate indications are underlined.

    Pulmonary sclerosing hemangioma (PSH) is a relatively rare benign tumor. However, as it occurs only rarely, the natural course of the tumor is not well understood. In the present study, a case is presented of a 35-year-old woman who underwent intermittent fevers for more than one year. This case highlighted fever as a rare symptom of PSH. Fever is possibly one of the symptoms of PSH, although it is less likely to occur. Another symptom of the patient was that the tumor grew quickly in two months. The lesion was diagnosed as multiple sclerosing hemangioma of the lung (i.e., PSH), in which papillary, solid and sclerotic patterns appeared. Immunohistochemical evaluation of the lesion revealed positive staining for thyroid transcription factor 1 (TTF1), epithelial membrane antigen (EMA), pancytokeratin (PCK) and cytoskeleton 7 (CK7). In the present case study, the biological activity of PSH was identified to be aggressive. A review of the literature was performed in order to comment further on the clinical and pathological features of this rare disease. PMID:28357098

    Infantile hemangioma, a common benign tumor of infancy, grows quickly in the first year of life, and then regresses slowly to fibrofatty tissue in childhood. The accumulation of fibrofatty tissue in hemangioma involution indicates adipogenesis during this period. Perivascular cells (PCs) from multiple organs display multi-lineage differentiation, including adipogenesis. So we supposed that PCs in hemangioma may contribute to the adipogenesis in the involution. In this study, PDGFR-β (+) PCs was isolated from hemangioma tissue (hemangioma-derived perivascular cells, Hem-PCs) by fluorescence-activated cell sorter. In vitro, Hem-PCs showed fibroblast-like morphology. Immunofluorescence staining and flow cytometry showed Hem-PCs expressed MSCs markers CD105, CD90, CD29 and vimentin, pericyte markers α-SMA and PDGFR-β, stem cell marker CD133, and the adipogenic transcription factor PPAR-γ, but not hematopoietic/endothelial markers CD45, CD34, CD31, and flt-1. In vitro inductions confirmed multi-lineage differentiation of Hem-PCs, especially strong adipogenic potential. Then a murine model was established to observe in vivo differentiation of Hem-PCs by subcutaneous injection of cells/Matrigel compound into nude mice. The results showed Hem-PCs differentiated into adipocytes in vivo. To the best of our knowledge, this is the first study reporting the isolation of multipotential PDGFR-β (+) PCs from hemangioma, and observing their adipogenic differentiation in vivo. PCs may be the cellular basis of adipogenesis in hemangioma involution, and may be the target cells of adipogenic induction to promote hemangioma involution.

    A low power, argon-pumped tunable dye laser was used to deliver yellow light of 577 nm. Individual blood vessels within port-wine stain hemangiomas were treated with a 0.1-mm beam of light using 8 X magnification. This technique permits excellent resolution of facial and nuchal port-wine stain hemangiomas in adults without the adverse complications of textural change, permanent pigmentation abnormality, or hypertrophic scarring.

    Hemangiomas are vascular tumors composed of blood vessels, frequently localized in the skin and subcutaneous muscles; their localization in the heart is exceptional. The most common localizations are the lateral walls of the left ventricle, the anterior wall, and the septum. Mostly, these tumors grow intracavitarily, rarely intramurally. We describe a singular case of left ventricular intramural hemangioma, detected and diagnosed using newer magnetic resonance imaging (MRI) modalities, confirmed by histopathological results, and treated successfully by surgery.

    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

    The successful treatment of vascular anomalies depends on profound knowledge of the biologic behavior of vascular lesions and their correct classification. On the base of the clinical course Mulliken and Glowacki developed a biologic classification that was accepted as official classification by the ISSVA (International Society for the Study of Vascular Anomalies). Based on an extended literature research, this manuscript will give an overview of different internationally accepted treatment concepts. Even if a wait-and-see strategy can be recommended in many cases of uneventful hemangiomas in infants the proliferative growth of such lesions requires an adequate treatment indication. Vascular malformations that persist lifelong require treatment in the majority of the cases, especially when clinical symptoms occur. Based on individual parameters such as the diameter, location or growth behavior, different therapeutic options as cryotherapy, corticosteroids, laser therapy, sclerotherapy, surgical intervention and/or embolisation can be performed successfully. None of those treatment concepts, however, represents the only treatment method of choice.

    A 59-year-old woman had a 1-year history of right vision loss. Her visual acuity was then 0.01 OD, and the critical flicker frequency (CFF) was 8 Hz OD. 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

    A 26-year-old woman (G2P1A1) presented with a 5-week history of multiple red marks on her body after a therapeutic abortion. A physical examination found 15 palpable red marks on her head, neck, chest, arms and legs. Proliferating endothelial cells, which expressed CD31, CD34, von Willebrand factor, but not Glut-1 and merosin, were observed in the lesional area by histopathological analyses. Histocompatibility antigen typing of 2 lesions was identical to a sample from peripheral blood. Accelerated regression was observed in 2 lesions treated by intralesional injection of betamethasone, while spontaneous regression was observed within 9 months in the remaining lesions without any treatment. Rapid growth, spontaneous regression and histological analyses in this case support the diagnosis of 'infantile hemangioma-like vascular lesion'.

    Ga-PSMA PET/CT was performed in a 68-year-old man to evaluate recurrent prostate cancer due to elevated serum prostate-specific antigen level. Images showed a focal uptake in the prostatic gland, suggesting local relapse, and an intense uptake in the 12th thoracic vertebra, with no morphological abnormalities in CT slices. In order to confirm extraprostatic disease and before radiotherapy planning, a full-spine MRI was performed, resulting with the morphological pattern of a vertebral hemangioma. Hystological analysis confirmed the local relapse in the prostate. No radiotherapy treatment was given to the vertebra, and after 1 year of follow-up without systemic treatment, prostate-specific antigen is still undetectable.

    Vertebral hemangiomas (VHs) are frequently asymptomatic lesions found incidentally during investigations for other spinal problems. Symptomatic VHs are less common, and there are few reports of compressive VHs in the literature. VHs with aggressive behavior present with low signal intensity on T1-weighted and high signal intensity on T2-weighted MRI. We present a case series of four patients with compressive VH, all of whom were neurologically compromised. Each of the four patients underwent preoperative arterial embolization followed by surgical treatment of their VHs. All patients recovered normal motor function after surgery. At follow-up (average 53 months), one patient had a recurrent tumor requiring reoperation and radiotherapy. Although it is rare, aggressive VH can be a devastating condition. Total surgical resection or subtotal resection with radiotherapy may be warranted.

    Between 1930 and 1959, more than 10,000 infants were treated at Radiumhemmet, Stockholm, with radium ({sup 226}Ra) needles and/or tubes for hemangioma of the skin. Absorbed dose to the brain, eye lenses, parotid glands, thyroid gland, breast enlarge, lungs, stomach, intestine, ovaries, testicles and bone marrow were calculated for each individual. The mean absorbed dose to the different organs ranged from 0.06 to 0.48 Gy. The highest absorbed dose was given to the breast (maximum 47.7 Gy). There was a wide dose range for each organ which was due mainly to differences in the distance between the applicator and the organ. The absorbed dose to all organs decreased on average by 32% during the study period. This was due to a 25% decrease in the treatment time and a change in the distribution of the treatment sites. 17 refs., 4 figs., 4 tabs.

    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. 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 HemSC in vitro and the vasculogenic and homing properties of HemSC in 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 i.v. delivery were significantly decreased in α6-integrin siRNA-transfected HemSC. In 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 antihemangioma therapy.

    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

    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

    Primary chest wall tumors occur infrequently; in particular, cavernous hemangioma of the chest wall is an extremely rare disease. We report a case of child with cavernous hemangioma of the chest wall, which was successfully resected. Obvious enlargement of the tumor and the appearance of pain were observed during a 2-year follow-up. In the present case, transcutaneous ultrasonography showed the appearance and disappearance of the mass. This was considered to be caused by the transfer of contents between the shallow and deep parts of the tumor. This may have resulted from serratus anterior muscle movement between the two-layered tumor. Transcutaneous ultrasonography, as well as magnetic resonance imaging, was therefore extremely effective for preoperative diagnosis. Transcutaneous ultrasonography is easily performed, even in children, such as in the present case. Because of its simplicity and usefulness, transcutaneous ultrasonography may be considered as the first-line imaging modality for diagnosis.

    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.

    We present a case of adult polispleny syndrome accompanied by cleft spleen containing a cavernous hemangioma and an aberrant right subclavian artery. Patients with polysplenic syndrome are usually lost in childhood and rarely reach adulthood. The most frequently accompanying vascular abnormality is an interrupted inferior vena cava with azygous-hemiazygous continuation. Arterial vascular anomalies are rather rare, and there are several reports in the medical literature where cases of childhood polyspleny syndrome are accompanied by pulmonary arteriovenous fistulas or a main hepatic artery originating from the superior mesenteric artery. The case presented here seems to be the first report of adult polysplenic syndrome with an aberrant subclavian artery and a splenic cavernous hemangioma. The possible congenital vascular anomalies which eventually could accompany adult polysplenic syndrome cases are clinically important for the approach to the patient and planning of eventual vascular interventions.

    A case of intractable hiccup developed by cavernous hemangioma in the medulla oblongata is reported. There have been only five previously reported cases of medullary cavernoma that triggered intractable hiccup. The patient was a 28-year-old man who was presented with intractable hiccup for 15 days. It developed suddenly, then aggravated progressively and did not respond to any types of medication. On magnetic resonance images, a well-demarcated and non-enhancing mass with hemorrhagic changes was noted in the left medulla oblongata. Intraoperative findings showed that the lesion was fully embedded within the brain stem and pathology confirmed the diagnosis of cavernous hemangioma. The hiccup resolved completely after the operation. Based on the presumption that the medullary cavernoma may trigger intractable hiccup by displacing or compression the hiccup arc of the dorsolateral medulla, surgical excision can eliminate the symptoms, even in the case totally buried in brainstem.

    The clinical objective in laser treatment of hemangiomas is to photocoagulate the dilated cutaneous blood vessels, while at the same time minimizing nonspecific thermal injury to the overlying epidermis. We present an in-vivo experimental procedure, using a chicken comb animal model, and an infrared feedback system to deliver repetitive cryogen spurts during continuous Nd:YAG laser irradiation. Gross and histologic observations are consistent with calculated thicknesses of protected and damaged tissues, and demonstrate the feasibility of inducing spatially selective photocoagulation when using cryogen spray cooling in conjunction with laser irradiation. Experimental observation of epidermal protection in the chicken comb model suggests selective photocoagulation of subsurface targeted blood vessels for successful treatment of hemangiomas can be achieved by repetitive applications of a cryogen spurt during continuous Nd:YAG laser irradiation.

    This paper presents a newly developed dermatological laser (with a central wavelength 975 nm) for application in therapies requiring deep penetration of tissue, e.g., cutaneous (dermal) neurofibroma (von Recklinghausen disease) and hemangiomas. This laser can work either in pulses or continues wave mode. Laser radiation is transmitted toward the application region by optical fiber with a diameter of 0.6 mm. The compact design of the laser facilitates its transport and increases the comfort of use.

    Abstract 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.

    Sixty-six cases of hemangioma were treated with CO2 laser alone (22 cases as a control group), or CO2 laser supplemented with He-Ne laser (44 cases of the treated group). Optimum power dosage was first sought on normal volunteers. Arteriolar vasculature and lymphatics were blocked 3 - 5 times with procaine hydrochloride (5:1) to minimize local blood congestion. Results show that the healing rate of the treated group was significantly higher than that of the control group (X3 equals 3.92, P < 0.05). Eleven cases (50%) were complicated with exudation in the control as compared with 3 cases (6.8%) in the treated group (P < 0.01). Of the 18 cases completely cured in the control group, the number of treatments averaged at 11.4 times, while of the 39 cases completely cured in the treated group, the average number of treatments was 5.9 times, which is also statistically significant (P < 0.01). It is considered that CO2 laser supplemented with He-Ne laser is superior than CO2 laser alone for the treatment of hemangioma. Furthermore, it is also proposed that the supplement of copper and Chinese herbal medicines may prevent the incidence of recurrence. Laser was used for the treatment of hemangioma in our country during the 1980s. In foreign literature, there were several reports using Nd:YAG and copper vapor laser for the treatment of agniomasimplex and nevus flammeus. Ar+ laser agglomeration was commonly used for the treatment of angioma conjunctive in our country, but the use of CO2 laser for the treatment of angioma epiderma is not well documented. We wish to report the use of CO2 laser supplemented with He-Ne laser for the treatment of hemangioma in our hospital from April 1988 to December 1989.

    Infant hemangioma (IH) is the most common tumor in infants, which affects 5-10% of white children. It is a tumor of vascular origin that appears in the first months of life. The indication for the treatment of the IH is not approved in the datasheet of the product, however it has been used in the infant hemangioma by topical administration as an alternative to oral propranolol, avoiding the main problems of the oral route (bradycardia and hypotension). The objective of this work is to study the physical and chemical (HPLC stability indicating method) stability of a 0.5% timolol gel for topical application during 60 days (considering the stability limit as 90% of initial concentration of timolol maleate). The gel was prepared with a polyacrylic acid derivative and the physical stability of the system was studied by visual control, rheological and mechanical characterization. The studied formulation guarantees the correct dose administering and stability after 60 days stored at 25 ± 2 °C and light protected (tube of aluminum). We have developed an easy topical gel for the treatment of infant hemangioma with physical and chemical stability higher than those provided by the majority of hospitals.

    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.

    The field of extracranial vascular anomalies is considered as special focus of pediatric otolaryngology and it has shown a rapid development during the last years. The reason for this interest is finally also due to the global acceptance of the classification introduced by the ISSVA (International Society for the Study of Vascular Anomalies). Hemangiomas are the most frequently observed vascular tumors. Today the systemic propranolol therapy is mostly used for therapy of hemangiomas requiring treatment. Increasingly, the topical application of beta blocker is discussed while the benefit in the head and neck seems to be limited. Vascular malformations are classified according to the morphology of the affected part of the vascular system in arterial, venous, arterio-venous, lymphatic, capillary, and combined vascular malformations. Conventional surgery, sclerosing therapy, and laser treatment are invasive options for the treatment of lymphatic malformations. The options for the treatment of venous malformations could be significantly improved during the last years. In this context, the use of Nd:YAG laser, the conservative treatment of the localized disseminated intravascular coagulation with low-molecular weight heparin, the re-discovery of bleomycin as effective sclerosing agent, and the improvement of alcohol-based embolization agents must be mentioned. Today the treatment with dye laser is the preferred therapy for capillary malformations and it is superior to other therapeutic options as for example photodynamic therapy. Arterio-venous malformations as representatives for high-flow lesions are the high-risk lesions.

    Class 3 semaphorins were discovered as a family of axon guidance molecules, but are now known to be involved in diverse biologic processes. 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.

    Cavernous hemangiomas of the gastrointestinal tract are extremely rare. In particular, the diagnosis of small bowel hemangiomas is very difficult in children. A 13-year-old boy presented at the outpatient clinic with dizziness and fatigue. The patient was previously diagnosed with iron-deficiency anemia at 3 years of age and had been treated with iron supplements continuously and pure red cell transfusion intermittently. Laboratory tests indicated that the patient currently had iron-deficiency anemia. There was no evidence of gross bleeding, such as hematemesis or bloody stool. Laboratory findings indicated no bleeding tendency. Gastroduodenoscopy and colonoscopy results were negative. To obtain a definitive diagnosis, the patient underwent capsule endoscopy. A purplish stalked mass was found in the jejunum, and the mass was excised successfully. We report of a 13-year-old boy who presented with severe and recurrent iron-deficiency anemia caused by a cavernous hemangioma in the small bowel without symptoms of gastrointestinal bleeding.

    Hemangioma of the small intestine is rare, and the preoperative diagnosis of it is difficult. We report a patient with gastrointestinal bleeding for whom Tc-99m-labeled red blood cell scintigraphy was useful in diagnosing cavernous hemangioma of the small intestine. A 25-year-old man was referred to our hospital for recurrent iron deficiency anemia. Because of the patient's severe anemia, imaging was performed to locate the bleeding lesion in the gastrointestinal tract. Scintigraphy with Tc-99m-labeled red blood cells revealed pooling indicating a tumor and extravasation of blood from the tumor. Scintigraphy with Tc-99m pertechnetate revealed no abnormal accumulation. Partial resection of the small intestine was done, and cavernous hemangioma of the small intestine was diagnosed by using the specimen of resected tissue.

    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

    Pulmonary sclerosing hemangioma (PSH) is a benign tumor with two cell populations (epithelial and stromal cells), for which genomic profiles remain unknown. We conducted exome sequencing of 44 PSHs and identified recurrent somatic mutations of AKT1 (43.2%) and β-catenin (4.5%). We used a second subset of 24 PSHs to confirm the high frequency of AKT1 mutations (overall 31/68, 45.6%; p.E17K, 33.8%) and recurrent β-catenin mutations (overall 3 of 68, 4.4%). Of the PSHs without AKT1 mutations, two exhibited AKT1 copy gain. AKT1 mutations existed in both epithelial and stromal cells. In two separate PSHs from one patient, we observed two different AKT1 mutations, indicating they were not disseminated but independent arising tumors. Because the AKT1 mutations were not found to co-occur with β-catenin mutations (or any other known driver alterations) in any of the PSHs studied, we speculate that this may be the single-most common driver alteration to develop PSHs. Our study revealed genomic differences between PSHs and lung adenocarcinomas, including a high rate of AKT1 mutation in PSHs. These genomic features of PSH identified in the present study provide clues to understanding the biology of PSH and for differential genomic diagnosis of lung tumors. PMID:27601661

    Endothelial glucose transporter 1 (GLUT1) is a definitive and diagnostic marker for infantile hemangioma (IH), a vascular tumor of infancy. To date, GLUT1-positive endothelial cells in IH have not been quantified nor directly isolated and studied. We isolated GLUT1-positive and GLUT1-negative endothelial cells from IH specimens and characterized their proliferation, differentiation, and response to propranolol, a first-line therapy for IH, and to rapamycin, an mTOR pathway inhibitor used to treat an increasingly wide array of proliferative disorders. Although freshly isolated GLUT1-positive cells, selected using anti-GLUT1 magnetic beads, expressed endothelial markers CD31, VE-Cadherin, and vascular endothelial growth factor receptor 2, they converted to a mesenchymal phenotype after 3 weeks in culture. In contrast, GLUT1-negative endothelial cells exhibited a stable endothelial phenotype in vitro. GLUT1-selected cells were clonogenic when plated as single cells and could be induced to redifferentiate into endothelial cells, or into pericytes/smooth muscle cells or into adipocytes, indicating a stem cell-like phenotype. These data demonstrate that, although they appear and function in the tumor as bona fide endothelial cells, the GLUT1-positive endothelial cells display properties of facultative stem cells. Pretreatment with rapamycin for 4 days significantly slowed proliferation of GLUT1-selected cells, whereas propranolol pretreatment had no effect. These results reveal for the first time the facultative nature of GLUT1-positive endothelial cells in IH.

    2013-01-01

    Background Pulmonary sclerosing hemangioma (SH) is an uncommon tumor. The aim of this study was to identify the origin of pulmonary SH and summarize its clinicopathologic features. Methods Data of 26 cases of pulmonary SH were collected and reviewed, including their clinical symptoms, chest radiological examinations, treatments, and pathological findings. Results Female patients of pulmonary SH were markedly frequent (n=23, 88.46%). Solitary mass or nodule in the lung fields was the most common manifestation (n=24, 92.31%), especially in the right middle lobe (n=9, 34.62%). There were two kinds of tumor cells: lining cells and round cells. All tumors contained a mixture of papillary, solid, sclerotic, and hemorrhagic patterns. Immunohistochemistry with a variable number of antibodies was performed for some cases. All of the detected specimens revealed strong reaction of lining cells with epithelial markers, such as thyroid transcription factor-1 (TTF-1), epithelial membrane antigen (EMA), cytokeratin (CK), pancytokeratin (PCK), and cytokeratin 7 (CK-7), while round cells were positive with TTF-1 and EMA. Until the end of last contact, none of the patients died or suffered from the recurrence of the disease after surgical treatment. Conclusions Pulmonary SH is a unique neoplasm of the lung with a characteristic solitary mass or nodule. Pulmonary epithelium might be the primary origin of the tumor cells. PMID:23587094

    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 hemangioma (IH) is the most common vascular tumor of infancy, and it uniquely regresses in response to oral propranolol. MicroRNAs (miRNAs) have emerged as key regulators of vascular development and are dysregulated in many disease processes, but the role of miRNAs in IH growth has not been investigated. We report expression of C19MC, a primate-specific megacluster of miRNAs expressed in placenta with rare expression in postnatal tissues, in glucose transporter 1–expressing (GLUT-1–expressing) IH endothelial cells and in the plasma of children with IH. Tissue or circulating C19MC miRNAs were not detectable in patients having 9 other types of vascular anomalies or unaffected children, identifying C19MC miRNAs as the first circulating biomarkers of IH. Levels of circulating C19MC miRNAs correlated with IH tumor size and propranolol treatment response, and IH tissue from children treated with propranolol or from children with partially involuted tumors contained lower levels of C19MC miRNAs than untreated, proliferative tumors, implicating C19MC miRNAs as potential drivers of IH pathogenesis. Detection of C19MC miRNAs in the circulation of infants with IH may provide a specific and noninvasive means of IH diagnosis and identification of candidates for propranolol therapy as well as a means to monitor treatment response.

    During the last 5 years, many studies have shown the efficacy of propranolol as first-line treatment for infantile hemangiomas (IHs), but not much has been written about the role of propranolol beyond the proliferation phase of IH (>1 year). Our aim was to assess propranolol efficacy and safety in the treatment of patients older than 1 year. A retrospective study of patients older than 1 year diagnosed with IH and treated in our vascular anomalies clinic between 2009 and 2013 was performed. Eighteen patients older than 1 year with a diagnosis of IH (15 girls, 3 boys) were identified. The mean age at the time of initiation of treatment was 25.7 months (range 13-72 mos). Single lesions were observed in 13 patients and multiple lesions in 5. Fifteen patients had focal lesions and three had segmental. The median duration of treatment with oral propranolol was 11.8 months (range 2-33 mos). Complete response was observed in 72.2% of the patients and partial response in 27.8%. Recurrence was observed in three patients 4.7 months after completion of therapy (range 0.3-8 mos). These patients required further therapy with propranolol for 6 more months. Bradycardia was documented in two patients and night terrors in one patient, which led to discontinuation of treatment. In our experience, propranolol may be useful in the treatment of IHs beyond the proliferation phase (>1 year old), but more studies are needed to support this observation.

    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.

    Children with a large vascular tumor and associated Kasabach-Merritt coagulopathy respond inconsistently to therapy and have a high mortality rate. For this reason, we undertook a retrospective study of 21 such patients, and focused on clinical, radiographic, and histopathologic features. The male to female ratio was 1:1.6. Tumor was noted at birth in 50 percent of patients; the remainder appeared throughout infancy. The location was cervicofacial (n = 2), shoulder/upper limb (n = 4), trunk including retroperitoneum (n = 11), and lower limb (n = 4). These tumors grew rapidly to large size and were characterized by cutaneous purpura, edema, and an advancing ecchymotic margin. In contrast to common hemangioma, magnetic resonance imaging showed diffuse enhancement with ill-defined margins, cutaneous thickening, stranding of subcutaneous fat, hemosiderin deposits, and small feeding and draining vessels. All tumors were Kaposiform hemangioendothelioma (KHE); none were infantile hemangioma. Light microscopy showed irregular lobules or sheets of poorly formed, small vascular channels infiltrating and entrapping normal tissues. Characteristic features included spindle-shaped endothelial cells, diminished pericytes and mast cells, microthrombi, and hemosiderin deposits. Wide endothelial intercellular gaps and incomplete basement membranes were seen by electron microscopy. Dilated, hyperplastic, lymphaticoid channels were prominent in one tumor. KHE in 14 infants was treated with interferon alpha-2a: 6 had accelerated regression; 2 had stabilization of growth; and 6 evidenced no response. The mortality rate was 24 percent (5 of 21); this included three infants with retroperitoneal KHE. Kasabach-Merritt phenomenon does not occur with common hemangioma. Rather it is associated with the more aggressive KHE and rarely with other vascular neoplasms. Variable response to current pharmacologic therapy underscores our inadequate knowledge of the pathogenesis of thrombocytopenia in

    The newly developed pulsed/cw dermatological laser (with wavelengths 975 nm) is applied for therapies requiring deep penetration of tissue e.g. cutaneous (dermal) neurofibroma (Recklinghausen disease) or hemangiomas. As the selected eight patients had been treated previously using pulsed a Nd:YAG laser a comparison of these therapies was possible. The results of cutaneous neurofibroma therapy using diode laser show an improvement compared with the case of Ho:YAG and Nd:YAG laser therapies - however this should be checked for a larger number of patients.

    The patient was a 72-year-old man who had a history of hepatic cyst, which had, however, not been followed up. It was noted that he had internal hemorrhage in the hepatic cyst as well as a contrast-enhanced tumorous lesion in the cystic wall. Further detailed examination could not rule out hepatic cystadenocarcinoma or cystadenoma, so a right hepatic lobectomy was performed. The lesion was histopathologically diagnosed as non-malignant cyst with angiogenesis simulating cavernous hemangioma and intra-cystic hemorrhage. Although this disease is difficult to diagnose, its diagnosis is not impossible as long as the disease is kept in mind.

    A primary intraosseous cavernous hemangioma located at the sphenoid bone with extensive involvement of the orbital roof and the lateral wall of the orbit is very rare. A 48-year-old woman presented with progressive right exophthalmos and diplopia. CT showed a bony mass lesion in the right sphenoid bone extending to the orbital bone. MRI showed an abnormal lesion in the sphenoid bone, which was heterogeneously enhanced with gadolinium. All of the abnormal bone was surgically removed, and histological examination confirmed a cavernous angioma. We also present a brief clinical and radiological review of seven previously reported cases.

    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

    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. PMID:27630480

    The cancer incidence was studied in 18,030 patients (33% males, 67% females) with skin hemangioma who were admitted to Radiumhemmet, Karolinska Hospital, Stockholm, Sweden, 1920-1959. Radium-226 sources were used in 12,821 patients, x-ray therapy was used in 2,515 patients, and no radiotherapy was given to 2,694 patients. Cancer incidence in the cohort was searched by record linkage with the Swedish Cancer Register for the period 1958-1982. The median age was 6 months for the treated patients and 8 months for the patients not receiving radiotherapy. In the group treated with radium-226 or orthovoltage x rays (greater than or equal to 100-kV peak), 224 cancers were observed (relative risk (RR) = 1.18; 95% confidence interval (CI) = 1.03-1.35). In patients given contact x rays, 10 cancers were observed (RR = 0.71; 95% CI = 0.34-1.30). In patients not treated with ionizing radiation, 34 cancers were observed (RR = 0.93; 95% CI = 0.64-1.29). In patients treated with radium-226 or orthovoltage x rays, an RR of 1.65 was observed for breast cancer (95% CI = 1.26-2.13) and an RR of 2.73 was found for soft tissue tumors (95% CI = 1.18-5.38). Patients with brain tumors, thyroid cancers, and bone tumors had received radiotherapy close to the tumor site more often than expected. For patients with breast cancer, no such difference was found. For cancers of the breast and thyroid, the RR was higher in patients given more than one treatment.

    It is unclear whether the process of spontaneous and chemically induced hemangiosarcoma and hemangioma formation in mice involves the transformation of differentiated endothelial cells (ECs) or recruitment of multipotential bone marrow-derived hematopoietic stem cells or endothelial progenitor cells (EPCs), which show some degree of endothelial differentiation. In the present study, immunohistochemical staining for hematopoietic stem cell markers (CD45 and CD34), EC markers (vascular endothelial growth factor receptor 2 [VEGFR2], CD31, and factor VIII-related antigen), and a myeloid lineage marker (CD14) was employed to better define the origin of hemangiosarcomas and hemangiomas in mice. Staining was negative for CD45, factor VIII-related antigen, and CD14 and positive for CD34, VEGFR2, and CD31, indicating that mouse hemangiosarcomas and hemangiomas are composed of cells derived from EPCs expressing CD34, VEGFR2, and CD31 but not factor VIII-related antigen. The lack of CD45 expression suggests that mouse vascular tumors may arise from EPCs that are at a stage later than hematopoietic stem cells. Since factor VIII-related antigen expression is known to occur later than CD31 expression in EPCs, our observations may indicate that these tumor cells are arrested at a stage prior to complete differentiation.  In addition, myeloid lineage cells do not appear to contribute to hemangiosarcoma and hemangioma formation in mice.

    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.

  6. Gene expression analysis reveals marked differences in the transcriptome of infantile hemangioma endothelial cells compared to normal dermal microvascular endothelial cells

    Background Infantile hemangiomas are benign vascular tumors primarily found on the skin in 10% of the pediatric population. The etiology of this disease is largely unknown and while large scale genomic studies have examined the transcriptomes of infantile hemangioma tumors as a whole, no study to date has compared the global gene expression profiles of pure infantile hemangioma endothelial cells (HEMECs) to that of normal human dermal microvascular endothelial cells (HDMVECs). Methods To shed light on the molecular differences between these normal and aberrant dermal endothelial cell types, we performed whole genome microarray analysis on purified cultures of HEMECs and HDMVECs. We then utilized qPCR and immunohistochemistry to confirm our microarray results. Results Our array analysis identified 125 genes whose expression was upregulated and 104 genes whose expression was downregulated by greater than two fold in HEMECs compared to HDMVECs. Bioinformatics analysis revealed three major classifications of gene functions that were altered in HEMECs including cell adhesion, cell cycle, and arachidonic acid production. Several of these genes have been reported to be critical regulators and/or mutated in cancer, vascular tumors, and vascular malformations. We confirmed the expression of a subset of these differentially expressed genes (ANGPT2, ANTXR1, SMARCE1, RGS5, CTAG2, LTBP2, CLDN11, and KISS1) using qPCR and utilized immunohistochemistry on a panel of paraffin embedded infantile hemangioma tumor tissues to demonstrate that the cancer/testis antigen CTAG2 is highly abundant in vessel-dense proliferating infantile hemangiomas and with significantly reduced levels during tumor involution as vascular density decreases. Conclusion Our data reveal that the transcriptome of HEMECs is reflective of a pro-proliferative cell type with altered adhesive characteristics. Moveover, HEMECs show altered expression of many genes that are important in the progression and prognosis

    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

    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 main goal of our study was the evaluation of treatment efficiency of two types of ablative laser-CO2 and Er:YAG (or ERB) treatment. 183 patients (Er:YAG—105 patients, CO2—78 patients) were analyzed to compare the curative effects and adverse events, such as loss of pigment and appearance of scars caused by these two lasers. The results of the study showed the slightly better effectiveness of Er:YAG laser radiation in comparison with CO2 laser in the case of treatment of small hemangiomas up to 3 mm in diameter. In the Er:YAG laser application the curative effect was in 99%, hypo-pigmentation occurred in 18%, and scars in 70% of all treatments. In the CO2 laser application the curative effect was in 97%, hypo-pigmentation in 52%, and scars in 77% from all treatments.

    Introduction Scalp congenital hemangiomas (CHs) are rare vascular malformations among infants; they can be associated with an array of complications, including cardiac and cosmetic issues. Here, we report the endovascular treatment of a premature infant with a suspected large right parietal scalp hemangioma and associated high-output cardiac failure. Case description A two-day-old female premature infant (29 weeks gestational age; 1330 g birth weight) was referred by the neonatologists to our department for consultation and potential treatment of a large right parietal CH causing abrupt hypotension and high-output cardiac failure. Doppler ultrasound imaging at bedside revealed areas of arterial-venous shunting from the scalp and the presence of a superior sagittal sinus waveform, consistent with intracranial venous drainage. To alleviate cardiac dysfunction secondary to this lesion, trans-arterial embolization via n-butyl cyanoacrylate (nBCA) glue and deployment of detachable coils was performed via umbilical artery to occlude the right superficial temporal and occipital artery branches supplying the CH. Following treatment, the infant continued to require ventilator management, vasopressor support, and correction of coagulopathy, but by post-operative day two, her condition improved remarkably and the mass size began decreasing. The patient was discharged after a relatively uncomplicated subsequent 2½-month course in the neonatal intensive care unit. Conclusion Endovascular therapy proved effective and safe in treating cardiac failure associated with scalp CH, despite potential complications associated with neuro-interventional surgery in premature infants. Appropriate consideration in this patient population should be given to factors including blood loss, contrast use, radiation exposure, operative time, and possible intra-/post-operative complications.

    The paper describes a clinical case of a female patient with severe obstructive sleep apnea syndrome in the presence of congenital hemangioma of the face, soft palate, and tongue concurrent with paroxysmal atrial fibrillation and atrial flutter, paroxysmal supraventricular tachycardia, and sinoatrial block (maximally up to 3.9 sec). Continuous positive airway pressure therapy could reduce the number of paroxysms of atrial fibrillation and atrial flutter, supraventricular tachycardia and eliminate sinoatrial block.

    Cavernous hemangiomas (cavernomas) of the spinal cord are rare congenital malformations that comprise less than 5% of all intramedullary lesions. Despite this rarity, we describe the third case of central neuropathic itch associated with intramedullary cavernoma. Since fewer than 10 cases of central spinal itch from all causes have been published, this concurrence suggests the possibility of a specific association. A middle-aged man developed chronic disabling neuropathic itch and pain affecting his left shoulder and arm after frank hemorrhage of a midcervical cavernoma. We hypothesize that the relatively rostro-dorsal location of his lesion increased its likelihood of causing itch as well as pain. The microscopic pathology of cavernomas, specifically their gliotic rim containing hemosiderin-laden phagocytes, fosters ectopic firing of nearby neurons and makes cranial cavernomas highly epileptogenic. We hypothesize that these pathological features predispose cavernomas to cause central itch if they are located near, but spare, the central itch projection neurons in lamina I of the dorsal horn. Quisqualate injections into the deeper layers (neck) of the dorsal horns of rats produce pathologically similar lesions. Such rats develop unilateral dermatomal hyperalgesia and self-injurious scratching and biting (autotomy). Although this pathological grooming is currently interpreted as a response to chronic pain, we propose that it more likely models scratching provoked by central neuropathic itch, as seen in our patient and others. Study of quisqualate-injected rats may provide leads towards new treatments for neuropathic itch.

    OBJECTIVE Symptomatic vertebral hemangiomas (SVHs) are a very rare pathology that can present with persistent pain or neurological deficits that warrant surgical intervention. Given the relative rarity and difficulty in assessment, the authors sought to present a dedicated series of SVHs treated using stereotactic radiosurgery (SRS) to provide insight into clinical decision making. METHODS A retrospective review of a single institution's experience with hypofractionated radiosurgery for SVH from 2004 to 2011 was conducted to determine the clinical and radiographic outcomes following SRS treatment. The authors report and analyze the treatment course of 5 patients with 7 lesions, 2 of which were treated primarily by SRS. RESULTS Of the 5 patients studied, 4 presented with a chief complaint of pain refractory to conservative measures. Three patients reported dysesthesias, and 2 reported upper-extremity weakness. Following radiosurgery, 4 of 5 patients exhibited improvement in their primary symptoms (3 for pain and 1 for weakness), achieving a clinical response after a mean period of 1 year. In 2 cases there was 20%-40% reduction in lesion size in the most responsive dimension as noted on images. All treatments were well tolerated. CONCLUSIONS SRS for SVH is a safe and feasible treatment strategy, comparable to prior radiotherapy studies, and in select cases may successfully confer delayed decompressive effects. Additional investigation will determine future patient selection and how conformal SRS treatment can best be administered.

    In a poorly equipped tropical setting, limb amputation is often considered as the only therapeutic solution for malignant tumors or large benign tumors. However it can be avoided by bone replacement using an avascular autologous fibular graft. This method was used in a young girl from Tchad presenting a giant cavernous hemangioma of the humerus. This technique allowed salvage of the extremity but resulted inevitably in radial paralysis. The time needed for bone healing was normal. This technique required minimum facilities and was perfectly biocompatible. It can be used in tropical settings where allograft techniques and prosthetic replacement are not available.

    Protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway plays a crucial role in the tumorigenesis and progression of multiple tumors, and has been shown to be important therapeutic targets for cancer. The present study aimed to explore the role and molecular mechanisms of AKT/mTOR pathway in human hemangioma (HA). Twenty-five cases of human HA tissues were collected. The expression of AKT, mTOR and proliferating cell nuclear antigen (PCNA) proteins was evaluated using semi-quantitative immunohistochemistry in biopsy samples in different phases of HA. AKT/mTOR pathway was blocked by recombinant small hairpin RNA adenovirus vector rAd5-AKT+mTOR (rAd5-Am), used for infecting proliferating phase HA-derived endothelial cells (HDEC). The expression of AKT, mTOR and PCNA was detected by Real-time PCR and Western blot assays. Cell proliferative activities were determined by MTT assay, and cell cycle distribution and apoptosis were analyzed by flow cytometry. As a consequence, the expression of AKT, mTOR and PCNA was significantly increased in proliferative phase HA, while that was decreased in involutive phase. Combined blockade of AKT/mTOR pathway by rAd5-Am diminished cell proliferative activities, and induced cell apoptosis and cycle arrest with the decreased expression of AKT, mTOR and PCNA in proliferative phase HDEC. In conclusion, the activity of AKT/mTOR pathway was increased in proliferative phase HA, while it was decreased in involutive phase. Combined blockade of AKT/mTOR pathway might suppress cell proliferation via down-regulation of PCNA expression, and induce apoptosis and cycle arrest in proliferative phase HDEC, suggesting that AKT/mTOR pathway might represent the important therapeutic targets for human HA.

    Purpose: To study the frequency and angiographic findings of arteriovenous shunts (AVS) associated with adult cavernous hemangiomas of the liver (CHL) on hepatic artery digital subtraction angiography (DSA) and optimize the imaging technique of DSA to improve its diagnostic efficacy.Methods: We retrospectively analyzed 43 intraarterial DSA procedures performed on 30 adults with CHL. Of the 30 patients 22 were found to have an AVS. Transcatheter arterial embolization with Lipiodol (L-TAE) was performed on 21 of these and radiographs were taken immediately after embolization to observe the distribution of the injected iodized oil. The results were compared with those of the AVS found on DSA images.Results: AVS were identified by DSA in 22 (73.3%) of 30 patients. All AVS were located in the peritumoral liver tissue and had a parallel track appearance, or early filling of small draining veins during the arterial phase of DSA. Radiographs taken immediately after L-TAE in 21 of the 22 cases with AVS showed iodized oil filling a few portal branches or draining veins as a result of incompletely occluded shunts in 11 patients. In 10 patients there was complete occlusion and no filling of any vein, or only the originating end of draining veins filled with iodized oil. No evidence of AVS was found in the other eight patients in this series, and in six of these the DSA was not considered diagnostic.Conclusion: The present study indicates that AVS are frequently seen in adults with CHL. DSA with high-quality images is helpful in identifying small AVS of CHL. The formation of an AVS in CHL may be closely related to the pathological changes in the peritumoral liver tissue.

    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.

    The effect of topical propranolol gel on the levels of plasma renin, angiotensin II (ATII) and vascular endothelial growth factor (VEGF) in superficial infantile hemangiomas (IHs) was investigated. Thirty-three consecutive children with superficial IHs were observed pre-treatment, 1 and 3 months after application of topical propranolol gel for the levels of plasma renin, ATII and VEGF in Department of General Surgery of Dongfang Hospital from February 2013 to February 2014. The plasma results of IHs were compared with those of 30 healthy infants of the same age from out-patient department. The clinical efficiency of topical propranolol gel at 1st, and 3rd month after application was 45%, and 82% respectively. The levels of plasma renin, ATII and VEGF in patients pre-treatment were higher than those in healthy infants (565.86 ± 49.66 vs. 18.19 ± 3.56, 3.20 ± 0.39 vs 0.30 ± 0.03, and 362.16 ± 27.29 vs. 85.63 ± 8.14, P < 0.05). The concentrations of VEGF and renin at 1st and 3rd month after treatment were decreased obviously as compared with those pre-treatment (271.51 ± 18.59 vs. 362.16 ± 27.29, and 405.18 ± 42.52 vs. 565.86 ± 49.66 P < 0.05; 240.80 ± 19.89 vs. 362.16 ± 27.29, and 325.90 ± 35.78 vs. 565.86 ± 49.66, P < 0.05, respectively), but the levels of plasma ATII declined slightly (2.96 ± 0.37 vs. 3.20 ± 0.39, and 2.47 ± 0.27 vs. 3.20 ± 0.39, P > 0.05). It was indicated that the increased renin, ATII and VEGF might play a role in the onset or development of IHs. Propranolol gel may suppress the proliferation of IHs by reducing VEGF.

    Background Multiple endocrine neoplasia type 1 (MEN1) is a rare inherited disorder characterized by the simultaneous occurrence of endocrine tumors in target tissues (mainly the pituitary, endocrine pancreas, and parathyroid glands). MEN1 is caused by mutations in the MEN1 gene, which functions as a tumor suppressor and consists of one untranslated exon and nine exons encoding the menin protein. This condition is usually suspected when we encounter patients diagnosed with tumors in multiple endocrine organs, as mentioned above. Methods A 65-year-old woman who underwent surgery for a pancreatic tumor (serous cystadenoma) 5 years previously was referred to our hospital due to neurologic symptoms of diplopia and left ptosis. Brain magnetic resonance imaging revealed a 3.4-cm lesion originating from the cavernous sinus wall and extending into the sellar region. It was thought to be a nonfunctioning tumor from the results of the combined pituitary function test. Incidentally, we found that she also had a pancreatic tumor, indicating the necessity of genetic analysis for MEN1. Results Genomic analysis using peripheral leukocytes revealed a heterozygous c.1621G>A mutation in the MEN1 gene that was previously reported to be either a pathogenic mutation or a simple polymorphism. We pursued a stereotactic approach to the pituitary lesion, and microscopic findings of the tumor revealed it to be an intrasellar cavernous hemangioma, a rare finding in the sellar region and even rarer in relation to oculomotor palsy. The patient recovered well from surgery, but refused further evaluation for the pancreatic lesion. Conclusion There is great emphasis placed on genetic testing in the diagnosis of MEN1, but herein we report a case where it did not assist in diagnosis, hence, further discussion on the role of genetic testing in this disease is needed. Also, in cases of pituitary tumor with cranial nerve palsy, despite its low prevalence, intrasellar cavernous hemangioma could be

    Approximately 10% of infantile hemangiomas (IHs) are the most common vascular tumors affecting children and are characterized by rapid growth, and can have destructive, disfiguring and even life-threatening consequences. Currently, propranolol is considered to be a safe and effective treatment option for problematic proliferating IHs. Recent studies have also revealed that microRNAs (miRNAs or miRs) play important roles in the regulation of angiogenesis. In this study, XPTS‑1 cells were used as a hemangioma-derived endothelial cell line constructed in our laboratory. Through a series of experiments, we discovered that miR‑382 is a novel miRNA associated with IHs, which was overexpressed in XPTS‑1 cells and was conversely downregulated by treatment with propranolol. In addition, we found that miR‑382 contributes to the progression of IHs. Our results revealed that propranolol inhibited XPTS‑1 cell migration and proliferation, and promoted apoptosis, and these effects were reversed by the restoration of miR‑382 expression by transfection of the cells with an miR‑382 overexpression vector. Further experiments revealed that the above-mentioned effects were associated with the phosphatase and tensin homolog (PTEN)-mediated AKT/mammalian target of rapamycin (mTOR) signaling pathway. The expression of PTEN was upregulated, while that of p-AKT, p-mTOR and p-p70S6K was downregulated by propranolol; these effects were partly reversed by the overexpression of miR‑382. On the whole, our study identified that the downregulation of miR‑382 by propranolol inhibits the progression of IHs via the PTEN-mediated AKT/mTOR pathway.

    Background Since beta blockers became the preferred treatment for infantile hemangiomas (IH), the number of patients eligible for treatment is increasing. Currently treatment of IH with beta blockers is mainly reserved for expert centers, where wait times are lengthening. This demonstrated the need for development of a more efficient and accessible way of providing care for children needing treatment for IH. An eHealth intervention, Hemangioma Treatment Plan (HTP), was developed to treat IH in regional hospitals with online support from an academic doctor. Objective Our goal was to evaluate the feasibility of the eHealth intervention by determining its use, acceptance, and usability. By evaluating the feasibility, usage can be predicted and points for improvement can be defined, thereby facilitating implementation of the intervention. Methods Parents of children with an IH, presenting between October 2012 and November 2013 at the tertiary expert Center for Congenital Vascular Anomalies Utrecht, requiring treatment with a beta blocker, were asked to participate in the digital HTP. Both parents and regional doctors were sent a study questionnaire. Acceptance and usability of the HTP were evaluated by using the modified Technology Acceptance Model. Results A total of 31 parents and 22 regional doctors participated in the eHealth intervention and received the questionnaire, and 25 parents and 15 doctors responded (response rates respectively 81% and 68%). A majority of the parents (96%, 24/25) and the regional doctors (87%, 13/15) considered the eHealth intervention useful in the care for IH. Most parents (76%, 19/25) and over half of the regional doctors (53%, 8/15) found the HTP easy to use. Technical problems using the HTP were reported by 28% (7/25) of the parents and 73% (11/15) of the doctors. The majority of parents (92%, 23/25) felt positive about usage of the HTP during treatment of their child. All regional doctors (100%, 15/15) felt positive about transition

    Purpose: To evaluate the therapeutic effect and safety of pingyangmycin-lipiodol emulsion (PLE) intra-arterial embolization for treating gigantic cavernous hemangioma of the liver (CHL).Methods: Three hospitals (Nanfang Hospital, Inner Mongolia Autonomous Region's Hospital and Huai He Hospital) participated in the study during 1997-2001. A total of 98 patients with CHL were embolized with PLE via the hepatic artery. The therapeutic effects including changes in tumor diameter, symptomatic improvement and occurrence of complications were evaluated for a period of 12 months after the procedure.Results: The tumor diameters decreased significantly from 9.7 {+-} 2.3 cm to 5.6 {+-} 1.6 cm 6 months after the treatment (P < 0.01), and then to 3.0 {+-} 1.2 cm at 12 months (P < 0.01). Transient impairment of liver function was found in 77 cases after embolization, 69 cases of which returned to normal in 2 weeks, and the other eight cases of which recovered 1 month later. The clinical symptoms were significantly relieved in all 53 symptomatic patients. Persistent pain in the hepatic region was found in two cases, and these two patients resorted to surgery eventually.Conclusion: Intra-arterial PLE embolization proves to be effective and safe in treating patients with CHL.

    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.

    AIM: To compare and analyze the contrast enhancement appearance of small hemangioma (SHHE) and small hepatocellular carcinoma (SHCC) with helical multi-phase CT scanning so as to determine their roles and pitfalls in the differential diagnosis of SHHE and SHCC. METHODS: The pre and postcontrast CT scanning of the liver in 73 cases (38 SHHE, 35 SHCC) were carried out. The first phase scan of the entire liver began at 30s after the injection of contrast medium, the second and third phases began at 70s, and 4 min respectively. The contrast enhancement patterns and characteristics of all lesions were observed and compared. RESULTS: In SHHE, 64.29% (27/42) had typical manifestations in two-phase dynamic scanning, such as peripheral dramatic high-density enhancement of the lesions with progressive opacification from the periphery toward the center, 30.95% (13/42) were hyperdense in both phases and 4.76% (2/42) were hypodense in both phases. In the third phase scanning, 96.67% (28/30) of SHHE were hyperdense and isodense. In SHCC 59.52% (25/42) presented typical appearances, such as hyperdense in the first phase and hypodense in the second phase, 23.81% (10/42) were hyperdense in the first phase and isodense in the second phase with 4.76% (2/42) of hypodense in both phases. In the third phase scanning, 85.71% (24/28) of SHCC were hypodense. CONCLUSION: According to the contrast enhancement patterns of SHHE and SHCC in the two-phase or multi-phase scanning by helical CT, diagnosis can be established in the majority of lesions, while some atypical cases needed MRI for further investigation.

    Tuberous sclerosis (TSC) is a autosomal dominant genetic disorder caused by mutations in either TSC1 or TSC2, and characterized by benign hamartoma growth. We developed a murine model of Tsc1 disease by gene targeting. Tsc1 null embryos die at mid-gestation from a failure of liver development. Tsc1 heterozygotes develop kidney cystadenomas and liver hemangiomas at high frequency, but the incidence of kidney tumors is somewhat lower than in Tsc2 heterozygote mice. Liver hemangiomas were more common, more severe and caused higher mortality in female than in male Tsc1 heterozygotes. Tsc1 null embryo fibroblast lines have persistent phosphorylation of the p70S6K (S6K) and its substrate S6, that is sensitive to treatment with rapamycin, indicating constitutive activation of the mTOR-S6K pathway due to loss of the Tsc1 protein, hamartin. Hyperphosphorylation of S6 is also seen in kidney tumors in the heterozygote mice, suggesting that inhibition of this pathway may have benefit in control of TSC hamartomas.

    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

    Цель — выявить возможности оптической когерентной томографии (ОКТ) в уточненной диагностике гемангиомы хориоидеи (ГХ). Материал и методы. Обследованы 27 больных (22 женщины, 5 мужчин) с монолатеральной ГХ. Возраст на момент постановки диагноза составлял 30—76 лет (в среднем 53,7±5,29 года). Толщина опухолевого узла варьировала в пределах 0,9—5,3 мм (2,17±0,41 мм; медиана 1,9 мм), диаметр основания — 2,64—13,86 мм (медиана 7,7 мм). Результаты. Оценивая ОКТ-симптоматику ГХ, можно сказать, что нарушение архитектоники сетчатки, в том числе ее кистозная дистрофия, возникают при проминенции опухоли более 1,8 мм, а отек сетчатки — чаще при ее бо́льшей толщине. Следует отметить, что появившиеся морфофункциональные изменения в сетчатке при ГХ прогрессируют крайне медленно. При исследовании аутофлюоресценции опухоль была представлена участком обширной гипоаутофлюоресценции различной интенсивности. Локальный фиброз, гиперплазия и атрофия ретинального пигментного эпителия (PПЭ) также представлены зонами гипоаутофлюоресценции. Участки гипераутофлюоресценции соответствовали зонам скопления липофусцина. Вокруг самого узла опухоли в двух случаях наблюдали обширные зоны умеренной гипераутофлюоресценции за счет наличия свежей субретинальной жидкости с повреждением фоторецепторного слоя; точечные участки гипоаутофлюоресценции в этих зонах, по данным ОКТ, соответствовали участкам атрофии РПЭ. Заключение. Офтальмоскопическая картина ГХ представляет определенные трудности в уточненной диагностике. Наряду с получившей широкое распространение флюоресцентной ангиографией, современные методы диагностики, такие как спектральная ОКТ (в том числе в режиме углубленного сканирования с выявлением хориоидальных признаков), а также исследование аутофлюоресценции в режиме MultiColor позволяют уточнить диагноз гемангиомы.

    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.

    Oral cavernous haemangiomas are common lesions which may require treatment due to episodes of bleeding when bitten or deformity particularly when involving the lips and/or cheeks. Surgery can be hazardous due to haemorrhage while cryosurgery tends to be tedious for large lesions and be accompanied by major oedema. Sclerosants produce hard bulky masses. Embolization is seldom helpful due to lack of arterial feeders. The Nd:YAG laser is proving a useful modality in the oro-facial region and appeared worth investigating for these lesions in a laboratory animal model, by thermography and in the clinical situation.

    Vascular lesions of the maxillofacial area are even more challenging than in other different body district, because of the high aesthetic and functional relevance of this area for the sense organs presence like eye, brain, tongue, ear and nose. For these reasons, we propose an accurate classification based on hemodynamic and histologic aspects usefulthat is for diagnostic and therapeutic planning. A female, 60 years old patient came to our observation showing a vascular lesion of the lower left lip, and complaining for aesthetical and functional impairment. To confirm the diagnosis of vascular malformation and to detect lesion flow rate or other possible localization, a Tc red blood cell scintigraphy was carried out. Result was a venous low flow lesion; hence, sclerotherapy by a 3% Polidocanol solution (Atossisclerol) followed by surgery was planned. The aim of this work was to propose a diagnostic and therapeutic scheme with an integration of ISSVA and a flow rate classifications for a three-step planning based on 1) the biological findings in an early age at the lesion discover with a pharmacological treatment; 2) Hemodynamic study of the lesions at growing age followed by sclerotherapy or embolization; 3) Imaging study of these lesions for patients candidate to surgery when after step 1 and step 2 diagnostic and therapeutic planning results were incompletely successful.

    Sommario INTRODUZIONE: La malattia di Niemann-Pick (NPD) tipo A e B è una patologia da accumulo di lipidi. Il tipo A è un disordine fatale dell'infanzia. Il tipo B è una forma non-neuronopatica ossevata sia nei bambini che negli adulti con possibile riscontro di epatomegalia e/o splenomegalia (nodulare) durante un esame ecografico. Il tipo C dipende da un difetto nel trasporto del colesterolo. METODI: Una donna di 21 anni si è presentata al Pronto Soccorso con febbre, faringodinia e dolore al quadrante addominale superiore sinistro. Gli esami ematochimici hanno evidenziato anemia, piastrinopenia, aumento delle AST, ALT, GGT, FA, LDH trigliceridi, colesterolo totale, e ridotto HDL. La PCR per CMV ed EBV era negativa. La radiografia del torace era negativa. L'ecografia transaddominale ha rilevato splenomegalia (>22 cm long axis) con una lesione ipoecogena irregolare subcapsulare al polo superiore compatibile con infarto splenico e la presenza di multiple lesioni nodulari iperecogene con diametro da 1 cm fino a 5. RISULTATI: È stata quindi eseguita una ecografia con mezzo di contrasto con SonoVue (Bracco) che ha confermato la presenza di un infarto splenico. Le lesioni nodulari mostravano un enhancement in fase arteriosa con wash out in fase parenchimatosa tardiva. La F-FDG-PET ha mostrato un uptake nodulare splenico. Nel sospetto di un processo linfoproliferativo è stata eseguita una splenectomia. La diagnosi è stata di NPD tipo B con infarto splenico e le lesioni nodulari sono risulate essere emangiomi. DISCUSSIONE: Concludendo, la CEUS ha confermato la diagnosi e l'estenzione dell'infarto splenico, ma l'enhancement nodulare atipico supportato dalle immagini F-FDG-PET è stato fuorviante, suggerendo l'ipotesi di lesioni linfomatose.

    Hemangiomas of the skull base are rare neoplasms and are easily misdiagnosed as acoustic neuromas when occurring in the internal auditory canal. Among these tumors, ossifying hemangiomas are characterized histologically be newly formed bone tissue within their substance. We describe a 26-year old female patient who presented with left-sided sensorineural hearing loss and tinnitus. T2-weighted magnetic resonance imaging demonstrated a bright space-occupying lesion of the internal auditory canal with extension to the geniculate ganglion. Bony erosions of the internal auditory canal were proved by high-resolution computed tomography. A hemangioma was suspected preoperatively and was resected via a middle cranial fossa approach. Histologically, new bone formations were found in a cavernous hemangioma. In general, radiologic findings can suggest a hemangioma of the internal auditory canal and help to differentiate it from acoustic neuroma. Based on the histological findings of intratumoral bone formation, the hemangioma in our patient was classified as an ossifying hemangioma. However, reactive bone formation at the borders of a tumor in the internal auditory canal can also be mistaken as new intratumoral bone formation.

    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.

    This case involves a possible complication of excessive bleeding or rupture of hemangiomas. Problems and anesthetic management of the patient are discussed. A 35-year-old man with Sturge-Weber syndrome was to undergo teeth extraction and gingivectomy. Hemangiomas covered his face and the inside of the oral cavity. We used intravenous conscious sedation with propofol and N2O-O2 to reduce the patient's emotional stress. It was previously determined that stress caused marked expansion of this patient's hemangiomas. Periodontal ligament injection was chosen as the local anesthesia technique. Teeth were extracted without excessive bleeding or rupture of hemangiomas, but the planned gingivectomies were cancelled. Deep sedation requiring airway manipulation should be avoided because there are possible difficulties in airway maintenance. Because this was an outpatient procedure, propofol was selected as the sedative agent primarily because of its rapid onset and equally rapid recovery. Periodontal ligament injection with 2% lidocaine containing 1: 80,000 epinephrine was chosen for local anesthesia. Gingivectomy was cancelled because hemostasis was challenging. As part of preoperative preparation, equipment for prompt intubation was available in case of rupture of the hemangiomas. The typically seen elevation of blood pressure was suppressed under propofol sedation so that expansion of the hemangiomas and significant intraoperative bleeding was prevented. Periodontal ligament injection as a local anesthetic also prevented bleeding from the injection site.

    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 /sup 99m/Tc 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. None of the metastatic, abscess, or cystic lesions had increased blood-pool activity at any time after injection. It is concluded that /sup 99m/Tc red blood cell imaging can distinguish hemangiomas from other focal liver lesions.

It is concluded that 99mTc red blood cell imaging can distinguish hemangiomas from other focal liver lesions.

    The appearance of focal hepatic lesions on /sup 99m/Tc-sulfur colloid images is nonspecific. As it is important to distinguish hemangiomas from other lesions prior to biopsy, a prospective study was performed using /sup 99m/Tc-labeled red blood cells. Dynamic perfusion and delayed blood-pool images (1-2 hours) were obtained and lesion activity categorized as increased, equal, or decreased compared with the liver. Of 21 patients studied, 9 (43%) had one or more hepatic hemangiomas, and 8 of these 9 patients (89%) demonstrated increased blood-pool activity. The 12 nonhemangiomatous lesions consisted of 7 metastatic tumors, 2 hepatomas, 1 cirrhotic nodule, and 2 hepatic cysts. None of these 12 patients had increased activity on delayed blood-pool images. Early dynamic images of hepatic hemangiomas demonstrated variable activity (vascularity) and were not useful in differentiating hemangiomas from other lesions. Sensitivity was 89% and specificity 100%. Although liver enzymes are usually normal with hepatic hemangiomas, they may also be normal in metastatic disease. The authors recommend that delayed blood-pool imaging be performed prior to biopsy, particularly in patients without a known primary tumor or those with normal liver enzyme levels.

    The accuracy of Tc-99m RBC studies of the liver to diagnose cavernous hemangiomas has been previously reported. The authors have reviewed 82 of these studies performed in the last four years to determine the prevalence of this benign lesion when it is suspected. Studies were performed in patients with focal solid abnormalities of the liver if the patient had no known primary or if there were no definitive clinical or laboratory findings to support the diagnosis of metastatic disease. Blood flow, immediate blood pool and one hour delayed blood pool images were obtained in all patients. The combination of decreased or normal blood flow and markedly increased blood pool is pathognomonic for patients having cavernous hemangiomas. Seventeen percent (14/82) of patients were found to have cavernous hemangiomas of the liver. The remaining patients had metastatic disease (38), abscess (6), hepatomas (6), and miscellaneous diagnosis (11). All patients diagnosed as having cavernous hemangioma have been followed for at least one year. Seven of the remaining patients were lost to medical follow-up. In the series no false positive or false negative results have been obtained; however, false negative cases are anticipated for small or thrombosed hemangiomas. RBC liver studies should be encouraged since 1) the diagnostic yield is high; 2) it is the diagnostic procedure of choice; 3) biopsy of these lesions can be catastrophic; and 4) therapy and prognosis is greatly altered if the liver lesions are proven to be benign.

    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.

    PHACES syndrome is a spectrum of anomalies, P, posterior fossa anomalies as Dandy-Walker malformation; H, hemangioma; A, arterial lesions of the head and neck (the most commonly detected include dysplasia, aberrant origin or course, hypoplasia, and absence or agenesis); C, cardiac abnormalities as aortic coarctation; E, abnormalities of the eye and S, sternal defect, that may be present in up to 2% of children with facial hemangiomas and 20% of children with segmental facial hemangiomas. The constellation of PHACES syndrome symptoms may vary significantly between different patients. Major and minor criteria for PHACES syndrome have been recently described in order to improve their classification and management. We report the case of a newborn with PHACES syndrome, who had additional congenital defects including ectopia cordis as the most severe form of midline defect. Although the list and variety of published cardiac malformations in PHACES syndrome are extensive, ectopia cordis has not been previously reported.

    Red blood cells labeled with 99mTc constitute a suitable intravascular agent for imaging of vascular abnormalities. Hemangiomas are characterized by low perfusion and a high blood pool. This ''perfusion blood-pool mismatch,'' not encountered in other lesions, may help in the specific diagnosis of this tumor. This is particularly so in cavernous hemangiomas of the liver where three-phase 99mTc-labeled red blood cell scintigraphy should precede liver biopsy. Red cell scintigraphy also is useful for establishing the vascular nature of hemangiomas of the head and neck and the skin and for diagnosis of venous occlusion. Heat-damaged red blood cells provide a specific spleen imaging agent. This should be used when patients with suspected splenic pathology have equivocal colloid scintigraphy.

    Rivulus marmoratus were exposed to 0, 10, 21, 45, 95, or 200 mg/liter diethylnitrosamine (DEN) for 6 weeks and examined 12 weeks after the end of exposure. Fatty change, hepatocellular glycogenosis, multiple basophilic foci, enlarged and distorted cells with or without an enlarged nucleus, and hyaline bodies and cytological alterations observed after exposure to DEN. Hemangiomas, cholangiomas, biliary cystadenomas, and glandular, trabecular and anaplastic hepatocellular carcinomas were observed at the 18th week. Only those fish exposed to 95 mg/liter DEN had cavernous hemangiomas and peliosis-like lesions, which could be a preneoplastic lesion preceding cavernous hemangiomas. Adenomatous hyperplasia of thyroid and granulomas were other chronic reactions caused by DEN toxicosis.

    Two-hundred-ninety-six patients with various vascular lesions of the face have been treated with argon laser LAK-1 in the Department of Dermatology Warsaw Medical Academy since April 1992. The diagnosis of the treated lesions was port-wine stains, multiple telangiectasiae and small, most often induced by trauma hemangioma cavernosum of the lip. Best results were achieved in the patients with small hemangiomas cavernosum of the lip and multiple telangiectasiae on the face. Cure rate in this group was 100%. In 112 port-wine stain cases fading of 50 - 75% comparing with the adjacent skin was achieved. With stress, the argon laser therapy is a method of choice for the treatment of hemangioma cavernosum, port-wine stains and multiple teleagiectasiae of the face.

    To create awareness of the benign lesions from which osteosarcoma may arise. Osteosarcoma is a rare tumour of bone the etiology of which is poorly understood, but it may arise from benign lesions. Malignant transformation in hemangiomas, in the absence of prior radiation, is exceedingly rare and the resulting neoplasm is usually an angiosarcoma. We report the case of a 30-year-old woman where investigation for thigh pain revealed a distal femoral hemangioma. She represented with pain and mass 18 years later, leading to a confirmed diagnosis of osteosarcoma at the same site. Osteosarcomas may arise from a variety of benign lesions. In this article we report the case of a histologically confirmed hemangioma which subsequently underwent malignant change into an osteosarcoma.

    Vascular anomalies are divided in two major categories: tumours (such as infantile hemangiomas) and malformations. Hemangiomas are common benign neoplasms that undergo a proliferative phase followed by stabilization and eventual spontaneous involution, whereas vascular malformations are rare structural anomalies representing morphogenetic errors of developing blood vessels and lymphatics. It is important to properly diagnose vascular anomalies early in childhood because of their distinct differences in morbidity, prognosis and need for a multidisciplinary management. We discuss a number of characteristic clinical features as clues for early diagnosis and identification of associated syndromes.

    Vascular tumors of the kidney are distinctly rare, and to date no large series have been reported. We analyzed a series of primary vascular tumors of the kidney to further delineate their clinicopathologic features and identify organ-specific morphologic features, if present. Twenty-five renal cases previously coded as "arteriovenous malformation," "hemangioma," and "angiosarcoma" were retrieved from the archives of 4 collaborating institutions and were reevaluated histologically. Tumors were classified according to the 2002 World Health Organization classification of tumors of soft tissue and bone. There were 18 males and 7 females (M:F=2.6:1) ranging from 21 to 95 years (mean 56.7 y). Lesions ranged from "microscopic" to 30 cm (mean 6.0 cm) and were tan-brown, cystic, and hemorrhagic. On re-review, cases were classified as arteriovenous malformation (n=3), capillary hemangioma (n=14), and angiosarcoma (n=8). Arteriovenous malformations were identical to their somatic soft tissue counterparts. Renal capillary hemangiomas often lacked a well-formed lobular pattern and 5 cases showed a "sieve-like" arrangement reminiscent of splenic sinusoids, a pattern previously noted by others (anastomosing hemangioma). All hemangiomas were noninfiltrative and lacked cytologic atypia and mitotic activity. GLUT-1, D2-40, and CD8 were performed in 3 anastomosing hemangiomas and were all negative. Angiosarcomas were diffusely infiltrative with extensive parenchymal destruction; all showed at least small areas of conventional vasoformative growth, but were frequently dominated by spindled and epithelioid histology. All cases were positive for some combination of vascular tumor-associated markers (CD31, CD34, and FLI-1). Cytokeratin expression was absent in all angiosarcomas. Follow-up was available for 15 cases: all patients with arteriovenous malformation and hemangioma with follow-up were disease free after complete excision; 4 cases of angiosarcoma died of the disease at 1, 1, 6

    OBJECTIVE Cavernous hemangiomas are benign congenital vascular abnormalities. Intracerebral cavernous hemangiomas have an appreciable risk of spontaneous hemorrhage. Little is known as to whether head trauma increases the risk of bleeding for these lesions. In this study, the authors present a case series of 3 patients with posttraumatic nonspontaneous hemorrhage of intracerebral cavernous malformations (CMs). For the first time, to the authors' knowledge, they propose that trauma might constitute a risk factor for acute hemorrhage in intracerebral cavernomas. METHODS The authors reviewed the charts of all patients with a new diagnosis of intracerebral cavernoma at their pediatric hospital between 2010 and 2014. Patients with a history of head trauma prior to presentation were subsequently studied to identify features common to these posttraumatic, hemorrhage-prone lesions. RESULTS A history of head trauma was identified in 3 of 19 cases. These 3 patients presented with seizures and/or headaches and were found to have acute hemorrhage within a cavernous hemangioma. None of these patients had any history of abnormal neurological symptoms. All 3 abnormal vascular lesions had associated developmental venous anomalies (DVAs). The 3 patients underwent resection of their respective vascular abnormalities, and the diagnosis of cavernous hemangioma was confirmed with postsurgical tissue pathology. All 3 patients had complete resolution of symptoms following complete excision of their lesions. CONCLUSIONS Trauma may represent a risk factor for acute hemorrhage in patients with CMs. The presence of associated DVAs may represent a risk factor for posttraumatic hemorrhage of cavernomas. Excision should be considered in such cases, if feasible.

    Individuals with PHACE syndrome (posterior fossa malformations, hemangiomas, arterial anomalies, cardiac defects, eye abnormalities, sternal cleft, and supraumbilical raphe syndrome) have reported dental abnormalities to their healthcare providers and in online forums, but dental involvement has not been comprehensively studied. A study was conducted at the third PHACE Family Conference, held in Milwaukee, Wisconsin, in July 2012. A pediatric dentist examined subjects at enrollment. Eighteen subjects were enrolled. The median age was 4.2 years (range 9 mos-9 yrs; 14 girls, 4 boys). Eleven of 18 patients had intraoral hemangiomas and five of these (50%) had hypomature enamel hypoplasia. None of the seven patients without intraoral hemangiomas had enamel hypoplasia. No other dental abnormalities were seen. Enamel hypoplasia may be a feature of PHACE syndrome when an intraoral hemangioma is present. Enamel hypoplasia increases the risk of caries, and clinicians should refer children with PHACE syndrome to a pediatric dentist by 1 year of age.

    Winging of the scapula due to benign lesion of ventral surface of scapula is one of the rare cause and difficult to diagnose in first place. We present two unusual cases of pseudo winging of scapula due to benign lesions of scapula. First case was of 23 year old male with solitary osteochondroma of ventral surface of scapula. Second was 38 year old female with hemangioma involving subscapular muscles. Both the patients presented to us with dull aching pain over right scapular and shoulder region of 6 months duration with gradually increasing pseudo-winging of scapula. On examination there was mild tenderness over superomedial border of scapula with scapular snapping5 or 'clunk' on hyper abduction of shoulder. Further radiographic evaluation of right scapular region revealed solitary osteochondroma of ventral surface of right scapula in first case whereas MRI revealed hemangioma of subscapular muscles in second case. Hemangioma was initially treated by weekly injecting sclerosing agent (Inj. Polidocanol) locally for 4 weeks. Both lesions were later treated by excision and subsequent follow up revealed disappearance of pain and winging of scapula. Conclusion Winging of the scapula due to solitary osteochondroma and subscapular hemangioma of the scapula may present with an initial diagnostic difficulty but appropriate knowledge of literature and diagnostic acumen can give excellent results.

    During the period of January 1984 - July 1993, we have treated 611 children with more than 2000 lesions of congenital vascular disorders (CVD) such as hemangiomas and vascular malformations. This number does not include the patients with port wine stains, which also have been treated by means of laser. Most of the CVD patients (n equals 467) presented hemangiomas of the face, the anogenital region, and the extremities, some were located in the trachea or mouth or in the urogenital tract. All of these hemangiomas were growing prior to intervention or showed complications such as bleeding, ulceration, superinfection, or obstruction. Nearly a quarter (n equals 144) of the patients presented vascular malformations, either of singular vessel type involvement or of mixed vascular genesis (venous, arterio- venous, veno-lymphatic or lymphatic) with various complications like tracheal obstruction or recurrent thrombophlebitis. According to our step program, which is based on a clinical classification, the hemangiomas were treated as early as possible, while the vascular malformations were only treated with laser when no other therapeutic technique (embolization, resection) was suitable. All patients were referred for laser treatment from other centers. The lasers used were Nd:YAG and Argon lasers with transcutaneous application with or without continuous ice-cube surface cooling or interstitial laser application. The treatments were performed either on in- or outpatient basis according to age, localization and with good to excellent results in most cases and a complication rate of less than 2%.

    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.

    Intrahepatic tumors in asymptomatic patients are seen with increasing frequency. Treatment is dependent of the histology; while follicular nodular hyperplasia (FNH) and hemangiomas need no further treatment, all other tumors should be resected. In a prospective study we investigated the usefulness of two-stage scintigraphy (TSS) for the differentiation. The cholescintigraphy was started with a perfusion study, followed by a scan in the parenchymal phase and in the excretion phase. There is a typical scintigraphic pattern for FNH (hyperperfusion, normal parenchymal uptake delayed excretion) and hemangioma (hypoperfusion, no uptake), while all other tumors may have a mixed pattern. Therefore a blood pool is added to look for a hemangioma, if there is no typical pattern for FNH in the cholescintigraphy. The TSS classified correct 21 of 23 patients with FNH, 17 of 18 with hemangiomas, all 3 with adenoma and 36 of 37 with primary malignant intrahepatic tumors. The TSS is more accurate than CT or sonography, safe and inexpensive and therefore the method of first choice in the differentiation of intrahepatic tumors.

    Blue rubber bleb nevus syndrome (BRBNS) is a rare clinical entity characterized by multiple venous malformations (hemangiomas) of the skin and gastrointestinal tract. These hemangiomas usually cause episodes of occult gastrointestinal bleeding leading to iron deficiency anemia, and also carry a significant potential for serious hemorrhage. The 99mechnetium (99mTc)-labeled red blood cell scintigraphy has traditionally been utilized in the localization of occult bleeding sites in patients with suspected vascular malformations, angiodysplasia, and Meckel’s diverticulum. We report the incremental value of 99mTc-labeled red blood cell hybrid single-photon emission computed tomography-computed tomography (SPECT-CT) over planar scintigraphy alone in a 12-year-old female patient with BRBNS.

    Background Maffucci syndrome, a congenital mesodermal dysplasia characterized by multiple enchondromas and hemangiomas, was first described in 1881, and 200 cases have been reported in the literature since then. Its etiology is unknown, there is no predilection for race or sex, and the development of lesions usually occurs in puberty. The risk of sarcomatous transformation is about 25%. Case presentation The initial investigation of the case reported here focused on the diagnosis and treatment of malignancy, and the first diagnostic hypothesis was thrombosed hemangioma. After histopathologic confirmation of soft tissue sarcoma, examinations were performed to stage the tumor and enchondromas were found in ribs. The final diagnosis was Maffucci syndrome with malignant transformation. Conclusion Treatment should aim at symptom relief and early detection of malignancies; no therapy is indicated for asymptomatic patients. As in the case reported here, bone or soft tissue lesions that grow or become painful should be biopsied. PMID:19144147

    Trisomy 13 mosaicism is a rare genetic disorder affecting a small minority of all trisomy 13 cases. It occurs when two cell populations that are karyotypically different are present in the same individual and are derived from a single zygote. As a rule, the phenotype is mitigated to a less dysmorphic appearance and longer survival, making genetic counseling a difficult task. Capillary hemangiomas are a common feature of full trisomy 13, seen in 27-56% of all cases. We report on an 18-months-old girl with extensive cutaneous anomalies, mild dysmorphic features, and slight psychomotor delay, without structural defects and provide an up-to-date review of all cases of trisomy 13 mosaicism with skin involvement. To our knowledge, this is the second clinical report of a patient with trisomy 13 mosaicism with hemangiomas and port wine stains, but no structural defects. © 2015 Wiley Periodicals, Inc.

    The Kasabach-Merritt syndrome is characterized by thrombocytopenia and localized coagulopathy associated with a hemangioma. Most techniques applied to eradicate the tumor or accelerate its involution (surgery, radiation therapy, embolization) are invasive and require transfusion of large amounts of blood products. In some cases, medical treatment is the only alternative. Efficacy of steroids and antifibronolytic agents has already been described, but even this approach is associated with the administration of blood products. We report two cases of infants with Kasabach-Merritt syndrome associated with cardiac and hepatic hemangiomas. At admission, both had signs of cardiac failure. They were successfully treated with prednisone and epsilon-aminocaproic acid (EACA). Blood products were not required once the diagnosis was made. These observations have important implications for the management of patients with Kasabach-Merritt syndrome because they show that even in severe cases blood transfusions can be avoided by the use of prednisone and EACA.

    Oculoectodermal syndrome is a rare disease characterized by the association of aplasia cutis congenita, epibulbar dermoids, and other abnormalities. This report describes the twentieth case of the disease. We report a 4-year-old female child who presented with the classical features of the syndrome: aplasia cutis congenita and epibulbar dermoids. Our case expands the clinical spectrum of the disease to include: diffuse hyperpigmentation (some following the Blaschko´s lines); hypopigmented skin areas on the trunk; arachnoid cyst on the right fronto-parietal border; rounded left side of the hippocampus; and dermoid cyst underlying the bulb-medullary transition. Our patient also reported infantile hemangioma on the right wrist and verrucous hemangioma on the left leg, the latter not previously described in the literature.

    Klippel-Trenaunay syndrome (KTS) is a rare congenital disease, and extensive cutaneous hemangiomas and abnormal venous vessels are characteristic. In our case, to manage her pregnancy with KTS, whole-body MRA was performed before delivery. A 29-year-old woman was referred at 28 weeks because of prominent vulvovaginal varicosities due to KTS. At 35 weeks, hypertrophy and multiple venous varicosities of her leg as well as massive vulvovaginal varicosities became prominent with a normal coagulation profile. Systematic MRAs revealed hemangiomas and varicosities in the right leg, the lower abdomen, and the pubic region, while no obvious AVM was detected around the bronchial tube and spine. We decided to deliver her baby by cesarean section at 37 weeks under general anesthesia, and a healthy baby was delivered. No blood transfusion was required. Prophylaxis against thrombosis was performed after the operation. She was discharged with her baby. Her vulvovaginal varicosities shrunk considerably one month later. PMID:22567516

    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.

    Venous malformation (VM) is the most common type of congenital vascular malformation (CVM). They are present at birth and are often symptomatic, causing morbidity and pain. VMs can be challenging to diagnose and are often confused with hemangioma in terminology as well as with imaging. An accurate clinical history and cross-sectional imaging are critical for diagnosis and for devising management.

    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

    Vascular anomalies included hemangiomas and vascular malformations (VMs). VMs are mediated by mutations in the endothelial cell-specific receptor tyrosine kinase Tie2 (TEK),which is essential for angiogenesis and vascular stabilization. We identified five types of Tie2 mutations in 80 patients with soft tissue or spinal VMs by PCR including the previously detected missense mutations 2690A>G (Y897C), 2740C>T (L914F), 2743C>T (R915C), and two nonsense mutations 2763G>A, 2688C>T, we identified Tie2 mutation in primary spinal VMs for the first time. Tie2 mutations were found to be absent in 33 patients with hemangiomas and DNA samples of VMs. In addition, we showed that Tie2 mRNA expression in spinal VMs was similar to soft tissue VMs, but obviously lower than infant hemangiomas (P<0.01). This study provides new insights into spinal VMs, the association of Tie2 and vascular anomalies needs to be further discussed.

    Rhabdomyomatous mesenchymal hamartoma (RMH) is a rare congenital malformation involving the dermis and subcutaneous tissue, of which there were 62 reported cases through 2014. We report RMH in two neonates presenting as a sacral skin tag. In both cases, magnetic resonance imaging (MRI) of the spine showed evidence of spinal dysraphism, including a lipomyelomeningocele and a tethered cord. Surgical repair of the defects was performed. Histopathologic examination of the skin tags showed a haphazard arrangement of mature skeletal muscle fibers and adnexal elements, consistent with RMH. The second patient also had a hemangioma on the sacrum and was diagnosed with LUMBAR (lower body hemangioma and other cutaneous defects, urogenital anomalies/ulceration, myelopathy, bony deformities, anorectal/arterial anomalies, and renal anomalies) syndrome, an association between cutaneous infantile hemangiomas of the lower body and regional congenital anomalies. The apparent association of paraspinal RMH with spinal dysraphism suggests that aberrant migration of mesodermally derived tissues (including skeletal muscle fibers) during neural tube development may be responsible for the pathologic findings in the skin. Additional study of patients with spinal dysraphism and congenital cutaneous lesions may further support this hypothesis.

    Kaposiform hemangioendothelioma (KHE) and tufted angioma (TA) are rare tumors mainly occurring in early childhood. Our recent results showed that ectopic overexpression of human Prox1 gene, a lymphatic endothelial nuclear transcription factor, promoted an aggressive behavior in 2 murine models of KHE. This dramatic Prox1-induced phenotype prompted us to investigate immunohistochemical staining pattern of Prox1, podoplanin (D2-40), LYVE-1, and Prox1/CD34 as well as double immunofluorescent staining pattern of LYVE-1/CD31 in KHE and TA, compared with other pediatric vascular tumors. For this purpose, we examined 75 vascular lesions: KHE (n=18), TA (n=13), infantile hemangioma (n=13), pyogenic granuloma (n=18), and granulation tissue (n=13). Overall, KHE and TA shared an identical endothelial immunophenotype: the neoplastic spindle cells were Prox1, podoplanin, LYVE-1, CD31, and CD34, whereas endothelial cells within glomeruloid foci were Prox1, podoplanin, LYVE-1, CD31, and CD34. The lesional cells of all infantile hemangiomas and pyogenic granulomas were negative for Prox1 in the presence of positive internal control. These findings provide immunophenotypic evidence to support a preexisting notion that KHE and TA are closely related, if not identical. Overall, our results show, for the first time, that Prox1 is an immunohistochemical biomarker helpful in confirming the diagnosis of KHE/TA and in distinguishing it from infantile hemangioma and pyogenic granuloma.

    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.

    Magnetic resonance imaging (MRI) of the liver has demonstrated to be quite sensitive in showing Hepatic Hemangioma as high intensity lesions in T2 weighted imaging sequence. Hepatic Hemangioma is a non-malignant tumor and has relative high occurrence rate among the general population. It is of importance to differentiate this benign abnormality from other high intensity malignant lesions, such as hepatoma, adenocarcinoma, or metastasis. The objective of our study was to investigate the feasibility of applying neural network to assist in the differentiation of the liver MRI lesions. Thirty-seven liver MRI studies were collected, this including twenty-three cases of hepatic hemangioma and fourteen cases of malignant tumors. all cases were clinically proven with the diagnosed pathological condition and verified by biopsy. Four quantitative features, adopted from published literatures and used clinically on a routine basis, were measured from MRI images. In this study, a multilayer and two layer backpropagation networks were used for performance comparison. By attempting various training methods, the accuracy of the two layer network had been improved from 74% to 83% by selecting the proper boundary set based on the euclidean distance for each data set in both classes when training the network.

    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

    Rationale. Infantile Hemangiomas (IH) are the most frequent tumors of vascular origin, and the differential diagnosis from vascular malformations is difficult to establish. Specific types of IH due to the location, dimensions and fast evolution, can determine important functional and esthetic sequels. To avoid these unfortunate consequences it is necessary to establish the exact appropriate moment to begin the treatment and decide which the most adequate therapeutic procedure is. Objective. Based on clinical data collected by a serial clinical observations correlated with imaging data, and processed by a computer-aided diagnosis system (CAD), the study intended to develop a treatment algorithm to accurately predict the best final results, from the esthetical and functional point of view, for a certain type of lesion. Methods and Results. The preliminary database was composed of 75 patients divided into 4 groups according to the treatment management they received: medical therapy, sclerotherapy, surgical excision and no treatment. The serial clinical observation was performed each month and all the data was processed by using CAD. Discussions. The project goal was to create a software that incorporated advanced methods to accurately measure the specific IH lesions, integrated medical information, statistical methods and computational methods to correlate this information with that obtained from the processing of images. Based on these correlations, a prediction mechanism of the evolution of hemangioma, which helped determine the best method of therapeutic intervention to minimize further complications, was established.

    GLUT-1, an erythrocyte-type glucose transporter protein expressed in juvenile hemangiomas, has recently been shown to be a sensitive marker of perineurial cells and their tumors in a small number of cases. However, GLUT-1 expression has not been systematically examined in other mesenchymal neoplasms. Prompted by a recent report of GLUT-1 expression in epithelioid sarcoma, a tumor not generally felt to show perineurial differentiation, we examined GLUT-1 expression in a wide variety of mesenchymal tumors. Sections from 247 mesenchymal tumors of a variety of histologic subtypes were retrieved from our archives and immunostained for GLUT-1 using heat-induced epitope retrieval and the DAKO ADVANCE detection system (DAKO, Carpinteria, CA). Scoring was as follows: negative (<5% of cells), 1+ (5%-25% of cells), 2+ (25%-50% of cells), and 3+ (>50% of cells). All benign nerve sheath tumors showed a peripheral rim of positive normal perineurial cells, with 2 neurofibromas and 3 schwannomas showing more extensive staining. Three of 4 perineuriomas showed strong GLUT-1 expression. All juvenile hemangiomas were GLUT-1 positive. GLUT-1 expression was also seen in a wide variety of benign and malignant mesenchymal tumors. However, GLUT-1 expression was absent in nonjuvenile hemangioma endothelial tumors and in almost all low-grade lesions that enter the histologic differential diagnosis of perineurial tumors, including low-grade fibromyxoid sarcoma, dermatofibrosarcoma protuberans, and myxofibrosarcoma. We conclude that GLUT-1 expression in mesenchymal tumors is by no means specific for perineurial differentiation, but may instead represent upregulation of this protein within hypoxic zones, secondary to upstream activation of proteins such as hypoxia-inducible factor 1-alpha.

    PHACE syndrome represents the association of large infantile hemangiomas of the head and neck with brain, cerebrovascular, cardiac, ocular, and ventral/midline defects. Cardiac and cerebrovascular anomalies are the most common extracutaneous features of PHACE, and they also constitute the greatest source of potential morbidity. Congenital heart disease in PHACE is incompletely described, and this study was conducted to better characterize its features. This study of the International PHACE Syndrome Registry represents the largest central review of clinical, radiology, and pathology data for cardiovascular anomalies in PHACE patients to date. 62/150 (41%) subjects had intracardiac, aortic arch, or brachiocephalic vessel anomalies. Aberrant origin of a subclavian artery was the most common cardiovascular anomaly (present in 31/150 (21%) of subjects). Coarctation was the second most common anomaly, identified in 28/150 (19%), and can be missed clinically in PHACE patients because of the frequent association of arch obstruction with aberrant subclavian origin. 23/62 (37%) subjects with cardiovascular anomalies required procedural intervention. A higher percentage of hemangiomas were located on the left side of the head/neck in patients with coarctation (46% vs. 39%); however, hemangioma distribution did not predict the presence of cardiovascular anomalies overall. In conclusion, PHACE is associated with a high risk of congenital heart disease. Cardiac and aortic arch imaging with detailed assessment of arch patency and brachiocephalic origins is essential for any patient suspected of having PHACE. Longitudinal investigation is needed to determine the long-term outcomes of cardiovascular anomalies in PHACE. PMID:24079520

    PHACE is a rare congenital neurocutaneous syndrome where posterior fossa malformations, hemangiomas, cerebrovascular anomalies, aortic arch anomalies, cardiac defects, and eye abnormalities are variably associated. We describe the prenatal detection and the postnatal course of a child with PHACE syndrome with a unique type of aortic arch anomaly consisting of proximal interruption of the aortic arch and persistence of the fifth aortic arch. The fifth aortic arch represented in this case a vital systemic-to-systemic connection between the ascending aorta and the transverse portion of the aortic arch allowing adequate forward flow through the aortic arch without surgical treatment.

A 20-year-old, 45 kg healthy female with a sphere shaped pendunculated hemangioma in the popliteal fossa of her left lower limb was applied with arterial tourniquet after exsanguination. The procedure was performed under general anesthesia. Soon after exsanguination and tourniquet inflation, the patient developed pulmonary edema which subsided after deflating the tourniquet. The clinical evolution, treatment and pathophysiology of this complication are described.

Case presentation We present the case of a Congolese female infant born with bilateral cleft lip and palate, hypotelorism, microcephaly, and capillary hemangioma on her face. She presented with a large sacrococcygeal mass (15.0 cm ×12.0 cm ×5.0 cm) with a cystic consistency and a positive transillumination. Conclusion This observation suggests that overexpression of certain genes on chromosome 13 may lead to tumor formation from remnant cells of Hensen’s node. PMID:26715863

    The diagnostic value of magnet resonance imaging for the diagnosis of pathological abdominal conditions has been limited sofar because of artefacts due to movement susceptibility. The current indications comprise: liver: differential diagnosis of metastases, cysts and hemangiomas, identification of small metastases, demonstration of malignant vascular invasion, evaluation of hemochromatosis; kidneys: evaluation of transplant rejection, analysis of complex cysts, demonstration of malignant tumoral invasion. The application of magnetic resonance will be greatly extended by the introduction of rapid image sequences and the application of specific contrast media.

    Various types of tumor can occur in the subungual space, including glomus tumors, subungual exostosis, hemangioma, epidermal cysts, and malignant tumors. While fibromatosis can occur at various sites throughout the body, it is very rarely seen in the toe. Here, we are the first to report a case of superficial fibromatosis mimicking a glomus tumor in the subungual space of the second toe. The presentation of this condition shows the possibility of encountering uncommon superficial fibromatosis in the distal phalanx of the toe, and suggests that superficial fibromatosis should be included in the differential diagnosis of a glomus tumor in the toe.

    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.

    Dermatologists encounter a wide range of cutaneous vascular lesions, including infantile hemangiomas, port-wine stain birthmarks, arteriovenous malformations, venous malformations, Kaposi sarcomas, angiosarcomas, and angiofibromas. 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.

They typically appear as round-to-oval, bright, red, dome-shaped papules and pinpoint macules measuring up to several millimeters in diameter. The histopathologic findings of a cherry angioma are consistent with a true capillary hemangioma, which is formed by numerous, newly developed capillaries with narrow lumens and prominent endothelial cells arranged in a lobular fashion in the papillary dermis.

    We report a case of a cystic abdominal mass on ultrasound which presented a diagnostic dilemma at 32 weeks gestation. A presumptive antenatal diagnosis of a subcapsular liver hematoma (SCH) was made based on the location and ultrasound appearance similar to SCH seen in pediatric and adult patients. Sequential evaluation of the mass showed an evolving ultrasound appearance which reinforced our initial impression of a subcapsular hematoma of the fetal liver. Postnatal ultrasound confirmed the resolving SCH as well as a previously undetected echo bright lesion characteristic of an infantile focal hemangioma directly adjacent to the resolving SCH. A review of the literature is provided.

    The appearance of subcapsular liver hematoma after a laparoscopic cholecystectomy (LC) is an infrequent complication and seldom studied. Some cases have been connected to ketorolac given during surgery and after surgery. Other described causes are : hemangiomas or small iatrogenic lesions that could be aggravated by administration of ketorolac. Coagulation dysfunction like circulating heparin as seen in hemathological diseases is cause of bleeding after aggressive procedures. We describe two cases of subcapsular liver hematoma after LC, both of them have been given intravenous ketorolac and one of them had multiple myeloma. We discuss the causes and treatment of it.

    A 26-year-old man underwent arterial switch surgery for transposition of the great arteries in infancy. During a routine evaluation, a nodule was detected in the left lower lobe on chest computed tomography. The tumor had enlarged at follow-up and he underwent surgical resection. Because of past cardiac surgery, the pericardium was defective; therefore, the heart was exposed to the pleural cavity and severe adhesions surrounding the left lung. We had to encircle the left main pulmonary artery to perform enucleation safely. The tumor was diagnosed as a pulmonary sclerosing hemangioma using permanent pathology results. PMID:26385193

    The authors have encountered benign liver masses as frequently as malignant lesions in children with hepatomegaly. 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.

    We propose a method for quantification of liver tumors using statistical characteristics of ultrasonic RF signals. Parameters of K distribution show the characteristics of a soft tissue. The proposed method of chi-square test(CST) can estimate the most appropriate parameters of K distribution, which are fitted to an observed amplitude distribution. Method of moment(MOM), method combining maximum likelihood and MOM(ML/MOM), and CST are compared on simulated RF signals. The CST is applied to RF signals of liver tumors including 38 hepatocellular carcinomas(malignancy) and 12 hepatic hemangiomas(benignancy). The accuracy of discriminant analysis are 78% and 50% for malignancy and benignancy, respectively.

    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.

    From NCBI Gene: Vascular endothelial growth factor (VEGF) is a major growth factor for endothelial cells. This gene encodes one of the two receptors of the VEGF. This receptor, known as kinase insert domain receptor, is a type III receptor tyrosine kinase. It functions as the main mediator of VEGF-induced endothelial proliferation, survival, migration, tubular morphogenesis and sprouting. The signalling and trafficking of this receptor are regulated by multiple factors, including Rab GTPase, P2Y purine nucleotide receptor, integrin alphaVbeta3, T-cell protein tyrosine phosphatase, etc.. Mutations of this gene are implicated in infantile capillary hemangiomas. [provided by RefSeq, May 2009

    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.

    In a consecutive medicolegal necropsy series benign hepatic tumours and tumour like conditions occurred in 52% of the 95 men aged 35-69 years. The incidence increased with age, mainly due to small bile duct tumours (n = 26; mean age 56.7 years; p less than 0.01; mean size 1.3 mm). The next most common tumours were cavernous hemangiomas (n = 19; mean age 53.9 years; mean size 5.2 mm) that were not related to age. Focal nodular hyperplasia (n = 3; mean size 8.0 mm) tended to occur in a younger age group (mean age 40.3 years; p less than 0.001). Multiple bile duct tumours were present in 46% and hemangiomas in 50% of the men studied. Liver cell adenoma, nodular regenerative hyperplasia, and peliosis hepatis were incidental findings (one case of each). Nodular regenerative hyperplasia was associated with the consumption of alcohol and a total dose of 21.5 g of testosterone. These results indicate that benign hepatic tumours and tumour like conditions are not rare in men but may remain undetected because of their small size. Images PMID:3950039

    The Fps/Fes tyrosine kinase has been implicated in the regulation of hematopoiesis and inflammation. Mice expressing an activated variant of Fps/Fes (MFps) encoded by a gain-of-function mutant transgenic fps/fes allele (fps(MF)) exhibited hematological phenotypes, which suggested that Fps/Fes can direct hematopoietic lineage output. These mice also displayed marked hypervascularity and multifocal-hemangiomas which implicated this kinase in the regulation of angiogenesis. Here we explored the potential involvement of Fps/Fes in the regulation of hemostasis through effects on blood cells and the vascular endothelium. Hematological parameters of fps(MF) mice were characterized by peripheral blood analysis, histology, and transmission electron microscopy. Hemostasis parameters and platelet functions were assessed by flow cytometry and measurements of activated partial thromboplastin time, prothrombin time, thrombin clot time, platelet aggregation, bleeding times and in vitro fibrinolytic assays. Hematological and morphological analyses showed that fps(MF) mice displayed mild thrombocytopenia, anemia, red cell abnormalities and numerous hemostatic defects, including hypofibrinogenemia, hyper-fibrinolysis, impaired whole blood aggregation and a mild bleeding diathesis. fps(MF) mice displayed a complex array of hemostatic perturbations which are reminiscent of hemostatic disorders such as disseminated intravascular coagulation (DIC) and of hemangioma-associated pathologies such as Kasabach-Merritt phenomenon (KMS). These studies suggest that Fps/Fes influences both angiogenic and hemostatic function through regulatory effects on the endothelium.

    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.

    From June 1st, 1989 to May 31st, 1990, 16,987 consecutive newborns were examined at the No. 48 Gynecological Pediatric Hospital of the IMSS National Medical Center, looking for external congenital malformations including esophageal atresias, anorectal malformations and congenital hip luxations, all easily detected during a routine exploration. Each deformed newborn assigned two control patients the following two newborn babies showing no birth defects. 308 deformed newborns were detected, an incidence of 1.81%. Among the most frequent defects were midline flat hemangiomas, polyotia, Down syndrome, congenital hip luxation and myelomeningocele. The only significant statistical difference found with respect to the control group was a greater family history of defects in the case group (P less than 0.0001). When comparing our results with those from other studies, including a study done locally 15 years ago, we found differences among specific malformations: congenital hip malformation, polydactylia, foot deformities, flat hemangiomas, nevus and polyotias. Yet, the overall frequency of defects found was similar.

    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.

    The hemangioma is a benign tumour located mostly in the region of head and neck. It can appear at any age but especially it is diagnosed among children. The disease can be successfully treated with surgery, criotherapy, propranolol or endovascular procedures. The rare case of the 59-year-old, male patient with huge heamangioma of the pharynx was shown in this paper. The patient was mildly symptomatic - he neglected difficulty with swallowing or breathing and there was no pain. The only one complaint was experiencing a worsened hearing in the left ear. The patient was referred to the laryngologist with acute pharyngitis and with the suspicion of peritonsillar abscess. In the ENT examination apart from acute tonsillitis, the tumour of pharynx was diagnosed. Diagnostic puncture of the tumour showed blood. Ambulatory treatment with antibiotics was administered. The inflammation of pharynx was cured but the tumour remained. In the ENT department the patient underwent diagnostic process including CT of the head, angioCT of carotid arteries and consultation of vascular surgeon. The diagnosis was established and patient was referred for endovascular treatment. The outcome of the embolization of hemangioma resulted in reducing the tumour size and decreasing patient's symptoms. The epidemiology, diagnostic problems and therapy were described.

    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.

    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

    Breast cancer incidence rates after radiation exposure in eight large cohorts are described and compared. The nature of the exposures varies appreciably, ranging from a single or a small number of high-dose-rate exposures (Japanese atomic bomb survivors, U.S. acute post-partum mastitis patients, Swedish benign breast disease patients, and U.S. infants with thymic enlargement) to highly fractionated high-dose-rate exposures (two U.S. tuberculosis cohorts) and protracted low-dose-rate exposure (two Swedish skin hemangioma cohorts). There were 1,502 breast cancers among 77,527 women (about 35,000 of whom were exposed) with 1.8 million woman-years of follow-up. The excess risk depends linearly on dose with a downturn at high doses. No simple unified summary model adequately describes the excess risks in all groups. Excess risks for the thymus, tuberculosis, and atomic bomb survivor cohorts have similar temporal patterns, depending on attained age for relative risk models and on both attained age and age at exposure for excess rate models. Excess rates were similar in these cohorts, whereas, related in part to the low breast cancer background rates for Japanese women, the excess relative risk per unit dose in the bomb survivors was four times that in the tuberculosis or thymus cohorts. Excess rates were higher for the mastitis and benign breast disease cohorts. The hemangioma cohorts showed lower excess risks suggesting ameliorating dose-rate effects for protracted low-dose-rate exposures. For comparable ages at exposure (approximately 0.5 years), the excess risk in the hemangioma cohorts was about one-seventh that in the thymus cohort, whose members received acute high-dose-rate exposures. The results support the linearity of the radiation dose response for breast cancer, highlight the importance of age and age at exposure on the risks, and suggest a similarity in risks for acute and fractionated high-dose-rate exposures with much smaller effects from low

    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.

    The term "ranula" is used to describe a diffuse swelling in the floor of the mouth caused by either a mucous extravasation or, less commonly, a mucous retention cyst derived from the major sublingual or submandibular salivary glands. The most common presentation of ranula is a painless, slow-growing, soft, and movable mass located in the floor of the mouth. Ranula may be simple or plunging. Simple ranula often present as masses in the floor of the mouth, limited to the mucous membranes. Diving ranulas extend through the facial plans, usually posterior to the mylohyoid muscle into the neck, and present as cervical masses. Thyroglossal duct cyst, branchial cleft cyst, cystic hygroma, submandibular sialadenitis, intramuscular hemangioma, cystic or neoplastic thyroid disease might be included in differential diagnosis. A variety of surgical procedures have been quoted in the literature ranging from marsupialization, excision of the ranula, sclerotherapy, and excision of the sublingual gland. The recurrence rate varies according to the procedure performed.

    Postpartum hemorrhage is an obstetrical emergency that represents the leading cause of maternal mortality. Severe hemorrhagic complications that could appear postpartum are the abdomino-pelvic hematomas, which result from the rupture of the pelvic vessels. We reported a very rare case of puerperal retroperitoneal subserosal hematoma of sigmoid colon following vaginal delivery, which was successfully managed by conservative methods. As far as we know, there are only a few case reports of intramural hematoma of sigmoid colon in literature, having other etiologies than vaginal delivery trauma. The particularities of the case consisted in the association of hemangiomas and the low risk thrombophilia. Diagnosis was based on the clinical exam and the paraclinical founding. Laparotomy is generally considered the last choice, in life threatening cases with hemodynamic instability, compression signs, and presence of contrast leakage on noninvasive imaging methods, but avoiding colonic resection after dissection represented the true challenge of the case.

    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.

    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.

    Vascular anomalies such as hemangiomas or vascular malformations can produce negative esthetic effects in the maxillofacial region. These negative effects are the main complaints of patients. The clinical therapeutic efficacy of cryotherapy and sclerotherapy in the treatment of these lesions was evaluated in 10 patients who were clinically diagnosed with vascular lesions. Lesions were submitted to either cryotherapy or sclerotherapy, and follow-up showed that cryotherapy and sclerotherapy both were clinically effective in treating oral vascular lesions. Cryotherapy is an easy to perform method that requires only 1 session, but the high cost of the equipment is a limiting factor. Sclerotherapy is a noninvasive treatment widely accepted by patients, but more than 1 session is required.

    Although clinical trials for new drugs are often limited in children because of safety concerns or restrictions, new therapies or novel strategies with old drugs have recently expanded dermatologic armamentarium for pediatric patients. Oral propranolol is currently the first choice in the treatment of alarming infantile hemangiomas. In atopic dermatitis, proactive strategy with topical calcineurin inhibitors can safely prevent disease exacerbation. Tacrolimus, in particular, is also useful for the treatment of vitiligo occurring in sensitive areas such as the eyelids. Among biologic drugs, use of etanercept is safe and efficient in children and adolescents with moderate-to-severe plaque psoriasis. Engineered tissues with special antimicrobial properties (silver-coated fabrics or engineered silk) are now used to treat eczema and fungal diseases in children. In athlete's foot, the use of 5-finger socks can also be helpful.
