A Case of Polypoid Sinusoidal Hemangioma

Abstract

Sinusoidal hemangioma is a rare variant of deep hemangioma. Clinically it develops in adults, predominantly females, and presents as a painless, bluish, solitary, deep dermal or subcutaneous nodule. Histologically they are characterized by a well-circumscribed lobulated architecture composed of dilated interconnecting, thin-walled vascular channels that frequently show a pseudopapillary pattern and a back-to-back arrangement with scanty intervening stroma. We report an unusual case of sinusoidal hemangioma, which showed polypoid growth on the trunk of a 39-year-old male.
