Arterioportal shunting, when associated with hemangioma, is usually small, peripherally located, and without hemodynamic significance. Proximal arterioportal shunting occurring in hemangioma has rarely been reported. Herein we report a patient with renal cell carcinoma who simultaneously was found to have a hyperdynamic hemangioma in the liver. The imaging features were ...

Prefrontal cortex (PFC) is a large area of the brain and its neonatal lesion with ibotenic or kainic acid is used to study the early abnormalities in neurodevelopment that lead to behavioral changes linked to schizophrenia. However, these exitotoxic drugs produce a large and asymmetric damage in the PFC. We ...

We present a previously undescribed, intravenously occurring papillary hemangioma of the lip in a 10-year-old girl. Maze-like anastomosing capillary loops were found within the numerous, dilated veins widely distributed in the submucosa. These peculiar endovascular papillae of bland endothelial cells plugged the lumens and bore a striking resemblance to the ...

PURPOSE: This study was designed to examine whether hepatic hemangioma can be differentiated from cyst by use of single-shot fast spin echo (SSFSE) sequence without contrast material. METHODS: SSFSE images with a short TE (90 msec) and a long TE (600-700 msec) were obtained in 30 patients with cyst (n= ...

Tufted angioma is a rare, benign, vascular tumor, characterized histologically by tufts of capillary-sized vessels in the dermis. Five patients were diagnosed over a 10-year period. All developed the lesions within the first year of life. Four were Chinese and one was Indian. There was no sex predilection. All the ...

A 59-year-old man with an enlarged left chest wall mass that had been followed up for 3 years underwent surgical resection. The mass was pathologically diagnosed as cavernous hemangioma of the rib. This is the fourth case of this rare disease to be reported. However, it suggests that hemangioma of ...

In 1989 Wilson Jones and Orkin first described tufted angioma, which has the unifying histologic feature of circumscribed angiomatous tufts and lobules within the dermis. Tufted angioma may take unusual forms clinically. We describe five children less than 3 years of age with tufted angiomas, demonstrating the variability of the ...

BACKGROUND: In recent years, many new cutaneous vascular proliferations have been described. This is partly due to the current epidemic of AIDS, which has forced dermatopathologists to establish the diagnosis of the earliest patch-stage lesions of AIDS-related Kaposi's sarcoma and some of the recently described cutaneous vascular proliferations that may ...

A 7-year-old Filipino girl presented to the dermatology clinic with a slowly enlarging plaque on the inner aspect of her upper left arm. Although she had this lesion since birth, it had gradually enlarged and become indurated and slightly painful. The histopathologic examination showed a vascular proliferation within the dermis, ...

Lymphatic malformations (LMs) are uncommon congenital lesions that may occur throughout the body, although the head and neck region is the most common site. Most LMs are seen at birth. However, they may present in adolescence or adulthood, mainly as a result of trauma or infection. We report the case ...

BACKGROUND: Angiofibromas are uncommon vascular tumors with a strong predilection for the nasopharynx of adolescent males. Although they are slow growing and histologically benign, they have the potential to cause significant morbidity with laryngeal involvement. METHODS: We describe the clinical characteristics, histopathologic findings, differential diagnosis, preoperative evaluation, and management of ...

Mulliken and Glowacki categorized vascular anomalies as either hemangiomas or malformations, with the former being the most common tumor of infancy. Despite distinct clinical, radiologic, and histologic findings, the two major types of vascular lesions are often confused. This complicates both patient care and interpretation of the medical literature. A ...

Benign neonatal hemangiomatosis (BNH) is a condition of multiple neonatal strawberry hemangiomas limited to the skin. Characteristically, a rapid proliferative growth phase is followed by a prolonged involutional phase. Regression of cutaneous lesions usually starts in the fourth month, but variations until complete involution are high for individial lesions. Disseminated ...

Although hemangiomas are the most common benign tumors in infancy, scrotal hemangiomas are extremely rare and comprise less than 1% of all hemangiomas. Scrotal hemangiomas that extend into adjacent areas of the perineum, thigh, or anterior abdominal wall may occasionally be seen. Ultrasound is recommended as part of the preoperative ...

INTRODUCTION: Extra-axial cavernous hemangiomas or angiomas [(hem)angiomas] are relatively rare lesions. They usually arise in relation to the dura mater intracranially or at the spinal level. Most of these lesions have been described in the middle cranial fossa at level of the cavernous sinus. Controversy still exists regarding the exact ...

A rare case of a mid brain venous angioma with obstructive hydrocephalus is described. A dilated draining vein from the lesion in the aqueduct as the cause of the hydrocephalus is highlighted, and interesting features of the pathology of venous angiomas and associated cavernous hemangioma are described. The management of ...

A 3-month-old male infant was found to have a protruding mass with irregular contour at the root of his nose since birth. The mass protruded more when he cried. It was diagnosed and treated as a hemangioma by laser surgery in another hospital. However, the lesion recurred 1 week later. ...

Cutis marmorata telangiectatica congenita and vascular twin naevi are rare vascular anomalies in which focal acantholytic dyskeratosis is usually not observed. We describe a 44-year-old-man who presented for evaluation of skin lesions that had been present since birth. Physical examination revealed anaemic macules adjacent to a naevus telangiectaticus on the ...

There is controversy over the histogenesis of Kaposi's sarcoma (KS) from lymphatic or blood vessel endothelium. D2-40 is a novel monoclonal antibody to an Mr 40,000 O-linked sialoglycoprotein that reacts with a fixation-resistant epitope on lymphatic endothelium. We sought to establish the selectivity of D2-40 for lymphatic endothelium in normal ...

The authors present an unusual case of massive enlargement of the right lower extremity that was treated as lymphedema secondary to filarial infection. A multiple-method approach beginning with scintigraphy led to the diagnosis of massive hemangioma with probable associated lymphatic proliferation. Abnormal local proliferation of vascular and lymphatic tissue is ...

Diffuse neonatal hemangiomatosis (DNH) is a rare disorder that first presents with multiple cutaneous and visceral hemangiomas during the neonatal period and has a high mortality rate. The authors report a long-term survivor of DNH who presented with multiple visceral hemangiomas without cutaneous lesions. Vascular endothelial growth factor (VEGF) may ...

Several types of cutaneous vascular proliferations have been described in areas of irradiated skin, including both benign lesions, such as benign lymphangiomatous papules, atypical vascular lesions, or benign lymphangioendothelioma, and malignant neoplasms such as high-grade angiosarcomas. This report describes the clinicopathologic features of 15 cases of different types of benign ...

Capillary hemangiomas are benign, vascular lesions of skin and mucous membranes that often occur in infancy and childhood. Capillary hemangiomas are most commonly found in the head and neck region. Capillary hemangiomas that occur in adults and on the lower extremities are uncommon. A clinical case involving surgical treatment of ...

The relative importance of vascular and Alzheimer's disease (AD) lesions, their interaction in the development of cognitive impairment and the very existence of mixed dementia induced by the potentiation of both mechanisms remain controversial. The aim of this study was to assess whether the patients with infarcts and lacunes have ...

Surgical treatment of brainstem lesions has been encouraged after the development of magnetic resonance imaging. However, direct approaches to intra-axial lesions in the brainstem still carry a high risk of morbidity because the neuronal structures can be injured along the entry routes. We present two patients whose pontine cavernous angiomas ...

Glomangiomas are characterized by cavernous vascular channels surrounded by glomus cells. Multiple glomangiomas, although usually painless, can be a few centimetres in size and appear as blue phlebectatic lesions. Surgical excision of multiple glomangiomas can lead to scarring and recurrences. Laser treatment using vascular lasers and CO2 lasers has been ...

We report 10 patients with lesions consistent with the clinical entity of rapidly involuting congenital hemangioma (RICH). These are congenital vascular tumors bearing some resemblance to infantile hemangiomas, but with important clinical differences. The lesions in our patients were firm, red or purple plaques or tumors, sometimes with surface telangiectasia ...

Cavernomas are well circumscribed lesions formed by sinusoidal vascular channels. They tend to slowly expand in size and carry a 0.7% to 1.1% annual risk of hemorrhage. Only 10% to 30% of intracranial cavernomas are located in the posterior fossa. When located in the brainstem they can cause recurrent hemorrhages ...

Vascular dementia (VaD) incorporates different vascular mechanisms and changes in the brain, and has different causes and clinical manifestations. Current criteria for VaD select an aetiologically and clinically heterogeneous group and this definitional heterogeneity has affected clinical trial results. Focus on a more homogeneous group, such as that with subcortical ...

Arteriovenous haemangioma is a benign tumor which in ear, nose and throat practice is generally found in the soft tissues of the oral cavity. Bone involvement is very uncommon. These lesions typically manifest themselves in infancy, with a tendency towards spontaneous resolution. The management options comprise simple observation, embolization or ...

Laser treatment of pigmented lesions can be a rewarding experience when appropriate lesions are treated. Accurate diagnosis of pigmented lesions is needed before treatment. In some lesions, adjuvant topical therapy is greatly beneficial, and for others it may be the only option. The treatment of melanocytic nevi is controversial but ...

We experienced a female patient with a giant arteriovenous fistula in her lumbar region, which was successfully managed by a combination of selective embolization and a subsequent total excision. Embolization of the giant arteriovenous malformation resulted in an immediate decrease in the cardiac output and an increase in systemic vascular ...

BACKGROUND: Infantile hemangiomas are common tumors, distinctive for their perinatal presentation, rapid growth during the first year of life, and subsequent involution-and for their expression of a unique immunophenotype shared by placental microvessels. Occasional "hemangiomas" differ from the classic form in presenting fully formed at birth, then following a static ...

BACKGROUND: A case of a solitary, thoracic, extradural, extraforaminal cavernous haemangioma causing a chronic neuralgia syndrome is presented. In the spectrum of spinal axis cavernous malformations, extradural lesions are exceedingly rare. A purely extraforaminal, paraspinal cavernous haemangioma has never been previously reported. METHOD: A 56-year-old woman suffered from a chronic ...

Hemangiomas and VMs are potentially complicated lesions that are often misdiagnosed and treated under the presumption that if left untreated, they will go away on their own. A well thought out multidisciplinary team put together to determine the most appropriate diagnosis of a lesion and to formulate and insititute a ...

Many topical agents and physical modalities have been used throughout the years to give the face a more youthful appearance. The goal has always been to effectively and consistently rejuvenate the face while minimizing the time of recovery and risk for complications. Because each person is unique, there is no ...

Current histologic and immunophenotypic criteria useful in the pathological diagnosis of benign vascular tumors and anomalies of childhood, with emphasis on infantile hemangiomas and vascular and lymphatic malformations, have been described and correlated with clinical presentation. The authors have emphasized recent advances in research that portend an emerging revolution in ...

BACKGROUND: Multiple eccrine hidrocystomas are benign cystic lesions that pose a significant treatment challenge due to their facial location and tendency to scar after traditional surgical and other destructive modalities. METHODS: A 585nm pulsed dye laser was used at fluences ranging 7.0 J/cm2 to 7.5 J/cm2 at 6- to 8-week ...

STUDY DESIGN: A retrospective analysis of a large single institution pediatric intramedullary tumor database. The database was searched for all pediatric intramedullary cavernous malformations. OBJECTIVES: To review the authors' experience with three pediatric intramedullary cavernous malformations, review the previous literature, and discuss the surgical management for these rare lesions. SUMMARY ...

Hemangioma rarely presents as an isolated middle ear lesion. Because congenital hemangiomas usually regress spontaneously, surgical excision is not always necessary. However, a hemangioma in the middle ear can be complicated by infection and hearing impairment. We present 2 cases to show contrasting management strategies, both with successful outcomes. Two ...

Vascular tumors are common in infancy, affecting as many as 10% of children. These lesions often follow a benign course, with an initial proliferative phase followed by spontaneous involution, and require no therapy. Others manifest explosive early growth and Kasabach-Merritt phenomenon, requiring therapeutic intervention. Occasionally, some bulky tumors threaten life ...

PURPOSE: To quantify the risk of misdiagnosis of focal hepatic lesions manifesting at ultrasonography (US) as typical hemangiomas in a population at high risk for hepatocellular carcinoma (HCC) and to identify the most effective approach to their diagnostic evaluation. MATERIALS AND METHODS: A total of 1,982 patients with newly diagnosed ...

It has been hypothesized that vascular injury may be an important mechanism of cryosurgical destruction in addition to direct cellular destruction. In this study we report correlation of tissue and vascular injury after cryosurgery to the temperature history during cryosurgery in an in vivo microvascular preparation. The dorsal skin flap ...

Brainstem vascular malformations can sometimes simulate other conditions such as multiple sclerosis and pontine glioma. We report a case of brainstem cavernous angioma for which clinical course and radiologic appearance were suggestive of a pontine glioma. The diagnosis was uncertain until the clinical and radiologic evolution made it clear that ...

PURPOSE: The Jefferson classification has been used to localize cavernous sinus lesions. However, this classification occasionally showed dissociation between identified localization and clinical findings. We investigated the clinical applicability of the newly proposed Ishikawa classification based on serial topographic sections of human cavernous sinus and the clinical findings. METHODS: In ...

BACKGROUND: Cerebral cavernomas are rare vascular anomalies and their expansile growth has been considered to be mainly due to recurrent hemorrhages. They are not generally reported to show aggressive behavior. CASE DESCRIPTION: A 27-year-old male presented with headache, visual disturbances, and a 17-year history of seizures. He was known to ...

A 49-year-old female presented with a mass at the genu of corpus callosum manifesting as vertiginous sensation persisting for a couple of months. The preoperative diagnosis based on neuroimaging was astrocytic tumor, probably an oligodendroglioma. The mass was totally excised through a left interhemispheric approach without postoperative neurological deficits. Histological ...

The abnormal patterns of cerebral convolutions range from severe to small anomalies restricted to tertiary gyri and sulci. Lesions within Glial-Pial barrier were found in examined cases with cortical developmental abnormalities. Anomalies and impaired function of vessels penetrating the cortex from meningeal plexus coexisted often with Glial-Pial barrier lesions. We ...

A seven-year-old entire male Old English sheepdog was presented with a well circumscribed, completely alopecic area on the top of its head, located where a rubber band had been used for several years. A punch biopsy was taken from the centre of the lesion and histological examination revealed cell-poor, interface ...

The authors studied a rare, congenital, cutaneous vascular anomaly that grows proportionately with the child and does not regress. A total of 53 patients were compiled from three vascular anomaly centers. These patients' lesions were analyzed for presentation, physical findings, radiologic and histopathologic characteristics, natural history, and outcome after resection. ...
