Nevus Comedonicus on Scalp: An Unusual Presentation.

Nevus comedonicus (NC) is a rare developmental anomaly of follicular infundibulum plugged with keratinous material that resembles comedo-like lesions. Frequently affected sites are face, neck, trunk, and upper arm. Few cases have been described on palms, soles, scalp, and genitalia. We hereby report a rare case of NC on scalp in a 14-year-old boy.
