• Smooth muscle hamartoma (SMH) is a benign hamartomatous condition that consists of a dermal proliferation of smooth muscle cells. We hereby report a case of multiple, acquired smooth muscle hamartomas on scalp. A 25-year old male had a 6-year history of multiple, asymptomatic, hyperpigmented plaques on scalp which have been progressively increasing in number and size. Histopathological examination revealed large thick walled blood vessels, in addition to the haphazardly arranged discrete smooth muscle bundles in the reticular dermis. This case of smooth muscle hamartoma is unusual in being acquired, having multiple lesions, involving scalp, and having thick walled blood vessels apart from arrector pili muscle bundles. It emphasizes on the wide spectrum of clinical and histopathological variations that may be associated with acquired smooth muscle hamartoma. This article is protected by copyright.
