Abstract

Cutaneous hamartomas are a group of heterogenous benign skin conditions demonstrating epithelial and mesenchymal components in varying proportions. Folliculosebaceous (cystic) hamartomas comprise a distinct group of uncommon cutaneous tumor-like malformations. Histologically, these lesions demonstrate varying proportions of adnexal and stromal tissues. We review the literature on folliculosebaceous hamartoma and report a case with smooth muscle as its only stromal component.
