Abstract
-
Smooth muscle hamartoma is a benign hamartomatous condition, presenting clinically as a skin-colored or hyperpigmented patch or plaque and histologically as dermal smooth muscle hyperplasia. It is thought that Becker's nevus and smooth muscle hamartoma are distinct entities at either end of a spectrum. It can either be congenital or acquired We herein report a case of acquired smooth muscle hamartoma with follicular spotted appearance. We consider it as a rare clinical variant of smooth muscle hamartoma, which is clearly different from Becker's nevus.
