Abstract:
A case of congenital pilar and smooth muscle nevus (CPSMN) is reported. CPSMN is a distinct clinical and histologic entity characterized by prominent vellus hairs accompanying a proliferation of smooth muscle within the reticular dermis. Plaquelike elevation and mild hyperpigmentation are variable features of this unusual organoid nevus.
