BACKGROUND AND PURPOSE The aim of this study was to establish the MR imaging characteristics of choroidal hemangioma and to compare them with those of uveal melanoma. METHODS Among 41 patients examined at 1.5 T (4-cm surface coil, T1-weighted and fast spin-echo T2-weighted sequences), 25 had uveal melanoma and 16 had circumscribed choroidal hemangioma. After i.v. bolus injection of gadopentet...

Atypical hemangioma (including sclerosing and/or hyalinizing hemangioma) of the liver is a rare variant of hepatic hemangioma, which is the most common benign hepatic tumor. Atypical hemangioma can be indistinguishable from malignancy, primary, or metastatic, based on imaging characteristics. We describe a case of a 70-year-old man with weight loss, occasional bloody stool, change in caliber of...

Submit Manuscript | http://medcraveonline.com it may present itself (Proteus in Greek means polymorph), being an extremely rare disease: about 200 cases have been described worldwide, with about 120 being alive [3]. Characterized by pigmented verrucous nevus and thickening of the skin, lipomas, hemangiomas, hemihypertrophy, gigantism of the extremities (hands and feet), visceral abnormalities a...

Oral verrucous carcinoma (VC) is a rare locally invasive tumor. The histopathological diagnosis of verrucous carcinoma should be accompanied with careful identification of tumors with a greater chance to become frank cancers. A comprehensive Google and PubMed search was carried out using “oral, verrucous carcinoma and immunohistochemistry” as the key searching terms. All the articles till date ...

Hepatic hemangioma is the most common benign tumor of the liver. Most such hemangiomas are small, asymptomatic, and have an excellent prognosis. Giant hepatic hemangioma has been reported in the literature, but the exophytic and pedunculated forms of hepatic hemangioma are rare. A 56-year-old woman was referred to our hospital under the suspicion of having a gastric submucosal tumor. Abdominal ...

BACKGROUND Vascular tumors of the kidney are rare tumors that are usually diagnosed and confirmed by histopathological examination due to the difficulty in definitive diagnosis by clinical and radiological examination. Anastomosing hemangioma is a rare variant of capillary hemangioma that mimics angiosarcoma. CASE REPORT Here, we present a case of a 55-year-old female with a history of partial ...

Hemangioma of the rib is a rare benign tumor that is often difficult to distinguish from malignant bone tumors. Rib hemangioma often shows bony disruption with a slight cortical disruption, extraosseous lesion, and expanded bone on computed tomography (CT). We report the case of a 68-year-old man with atypical rib hemangioma with a slight cortical disruption and no expanded bone. The tumor show...

Incontinentia pigmenti is a rare X-linked genodermatosis that affects mainly female neonates. Skin manifestations are the most common and occur in four quite distinct phases. A female infant presented vesiculobullous lesions on trunk and limbs, and a verrucous lesion on the right palm. Biopsy revealed eosinophil exocytosis and pigment incontinence, confirming the clinical hypothesis. Although u...
