["Tufted angioma". A benign vascular tumor to differentiate with Kaposi sarcoma].
Among recently characterized vascular tumors, tufted angioma or angioblastoma is a benign acquired slowly progressive cutaneous tumor, which most commonly arises in the neck and upper trunk in children and young adults. This case report emphasizes the clinical and histological features of tufted angioma. Light microscopic examination reveals numerous lobules of closely packed capillaries scattered throughout the dermis. Vascular lumina are difficult to define. There are no atypical cells. Familiarity with tufted angioma should prevent this lesion from being misdiagnosed as malignant vascular tumor arising in young persons, especially Kaposi's sarcoma.
