다국어 초록 (Multilingual Abstract)

Microvenular hemangioma is a relatively rare, acquired, and slow-growing benign vascular lesion that usually arises as a small, reddish papule or plaque in young to middle-aged individuals. It commonly occurs on the arms, trunk, or legs. Histologically, it consists of irregular branching capillaries and venules involving the full thickness of the dermis. Herein, a 29-year-old woman presented for 2 years with an asymptomatic 1x1cm erythematous papule on the chin. Histological examination showed vascular proliferation of thin-walled blood vessels throughout the dermis. The vascular lumina were often collapsed but conspicuous. The endothelial cells are mostly flattened or slightly plump. Many flattened endothelial cells show immunoreactivity for CD31. There was noobvious nuclear atypia. We report this case of microvenular hemangioma developing on the chin, an unusual location.
