Hereditary haemorrhagic telangiectasia (HHT) is a familial, autosomal, dominant, multi-system, vascular, dysplasia. Besides repetitive epistaxis, cutaneous eruptive macules and nodules lead to recurring bleeding and cosmetic problems. We report on a pilot study of four cases of HHT in which cutaneous lesions were treated with a pulsed neodymium:yttrium-aluminum-garnet (Nd:YAG) laser ...

Cerebral cavernous malformation are congenital vascular abnormalities that have been reported in 0.4% of the population; they represent 5-13% of all cerebrovascular malformations. Onset of cerebral cavernous malformations may be associated with seizures, intracranial hemorrhages, focal neurological deficit or migraine-type headaches. Some patients may require surgical intervention due to hemorrhage. ...

Vascular malformations or even hemangiomas need therapeutic intervention if they start to cause clinical symptoms or personal discomfort. Different therapeutic modalities, including cryotherapy, corticosteroids, laser therapy, sclerotherapy, surgery, and/or embolization, can be performed successfully. Sclerotherapy with monoethanolamine is a relatively simple and effective method to treat low flow vascular lesions. ...

BACKGROUND: Most cutaneous hemangiomas involute spontaneously. However, the lesion existing on the face poses a cosmetic problem while waiting for involution. CASE REPORTS: Three hemangioma cases were treated by repeated local injection of 5% ethanolamine oleate solution. The lesions flattened and markedly reduced in size as shown by clinical and ...

Management of unresolved hemangiomas and venous malformations is a real challenging problem because of their grotesque nature and aesthetic considerations. In our study we have used percutaneous injection of N-butyl cyanoacrylate (NBCA) in such lesions to make these lesions amenable to easy excision. When the NBCA comes in contact with ...

Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder characterized by skin tumours derived from peripheral nerves. It is a clinically diagnosed disorder of a mainly cosmetic concern. There are different excision modalities for treatment of cutaneous neurofibromas; however, none is considered to be universally accepted treatment. This study was ...

Lobular capillary hemangioma (pyogenic granuloma) is a common vascular proliferation that typically occurs in the superficial dermis, although rarely a subcutaneous form has been reported. Although these lesions are considered benign, localized recurrence after excision and satellite spread of the lesions are known phenomena. A case of lobular capillary hemangioma ...

A 3-month-old girl presented to the Department of Pediatric Surgery because of a strangled inguinal hernia. The exploration using an inguinal approach showed a blue-reddish, moderately firm, circumscribed subcutaneous mass. Pathologic examination of the resected tissue confirmed the diagnosis of capillary hemangioma. To the authors' knowledge, this is the first ...

An increasing number of studies suggest a vascular contribution to Alzheimer's disease (AD). One major question these findings raise is whether vascular disease enhances the formation of AD-like lesions, or whether vascular disease just adds to clinical severity. We examined this question in a fully characterized autopsy sample based on ...

CONTEXT: Vascular tumors comprise a minor subgroup of tumors arising in the breast and represent variants of hemangiomas and angiosarcomas. Diagnostic challenges may arise when differentiating hemangiomas from types I and II angiosarcomas. Ki-67 expression has been used as an adjunct to distinguish between benign and malignant lesions exhibiting histologic ...

Hemangiomas are tumors of vascular origin comprising approximately 7% of all benign tumors. Intramuscular hemangioma is a rare condition and hemangiomas of the head and neck make up less than 15% of intramuscular hemangiomas. Temporalis muscle is an uncommon location for intramuscular hemangioma and seldom reported in the literature. Radiological ...

Venous malformation (VM) is the most common congenital vascular malformation (CVM), which usually presents as a single lesion in the majority of cases. It also presents as a mixed lesion combined with other CVMs (e.g. lymphatic malformation and arteriovenous malformation [AVM]). Therefore, the diagnosis of VM should include an appropriate ...

Tufted angioma is a rare cutaneous angiomatous proliferation named because of its characteristic histologic pattern of grouped dermal capillary tufts. Lesions usually begin in infancy or early childhood but rarely are congenital. Clinical manifestations are dull red coalescent papules and plaques, most commonly located on the neck, shoulders, and upper ...

Mixed type dementia (MD) refers to a combination of Alzheimer disease (AD) and vascular encephalopathy (VE) and other dementia disorders, but the distinction between these diseases is difficult. For the diagnosis of MD, the clinical/neuroimaging criteria of probable AD plus vascular cognitive impairment (VCI) as separate entities are used. Both ...

Cavernous malformations are benign vascular lesions of the central nervous system that lack intervening normal brain parenchyma. They can be seen almost anywhere that normal vasculature is available. Lesions are raspberry-like, thin-walled vascular sinusoids without smooth muscles containing hemosiderin deposits. Cerebral cavernous malformations are characterized by small bleedings. Their size ...

Benign vascular lesions include various forms whose classification has created some controversies in the literature. The observation of two rare cases of vascular bulge of the external ear canal prompted us to analyze the essential features of these lesions. One case was observed during an episode of otitis media, the ...

BACKGROUND: Ocular vascular hamartomas may present as isolated lesions or as part of a multisystemic congenital syndrome known as vascular phakomatoses. These syndromes are characterized by ocular, cerebral, and cutaneous lesions. Although each of these lesions manifests distinct characteristics, there may be overlapping characteristics and manifestations attributable to a common ...

Epithelioid hemangioendothelioma is an extremely rare vascular bone tumor with a slow growth and poor prognosis. The term was designed to describe neoplasms that had an appearance in between hemangiomas and sarcomas. Various synonyms for epithelioid hemangioendothelioma are used clinically: low grade anaplastic angiosarcoma, cellular hemangioma, histiocytoid hemangioma and angioendothelioma. ...
