Acquired Agminated Acral Angioma: A Novel Vascular Lesion

Arch Dermatol. 2005;141(5):646-647. doi:10.1001/archderm.141.5.646

Vascular lesions are classified based on clinical, histologic, and immunohistochemical findings. Classification is often difficult because of overlapping features. We report a case of a clinically distinct angioma, with the findings of histologic and immunohistochemical studies supporting its vascular origin. The term we propose for this lesion is acquired agminated acral angioma.

A 30-year-old woman presented with an asymptomatic lesion that had been present on her right leg for at least 20 years. Although the lesion had been stable for years, it had recently begun to appear more raised. There was no history of trauma to the leg prior to development of the lesion. The patient was otherwise healthy. Physical examination demonstrated a 5.0×3.0-cm plaque consisting of agminated, discrete, red papules and macules (Figure 1).
