Papular angioplasia is a benign vascular tumor characterized by asymptomatic red papules on scalp or face. A 65-year-old woman had a dome shaped red papule on her forehead for 10 years. Histopathologic findings of the lesion showed vascular proliferations composed of atypical endothelial cells, some of which were protruded into vascular lumina or arranged in two to three layers. Fibroblast-like or histiocyte-like cells were scattered around the vessels in the dermis. Both endothelial cells and fibroblast-like or histiocyte-like cells were stained with anti-factor VIII-related antigen antibody. (Ajou Med J 1999; 4(1): 69-71)
