Smooth muscle hamartomas are sub-divided into congenital or acquired; the latter is a rare entity with less than 20 cases being reported in the English literature. Most often asymptomatic, acquired smooth muscle hamartomas follow an indolent course. Treatment in the form of surgical excision can be utilized for symptomatic or cosmetic purposes. Here, we report the first case of an acquired smooth muscle hamartomas of the shin which also uniquely presented with hidrosis. This case highlights the varied clinical spectrum of acquired smooth muscle hamartomas.
