Erythromelanosis follicularis faciei et colli. A case report.

The thirteenth case of erythromelanosis follicularis o the face and neck is reported and attention is called to this entity. Characteristically, it affects males in adolescence or young adulthood. It begins symmetrically on the preauricular cheeks and imperceptibly spreads onto the temples and lateral aspects of the neck. It presents an irregularly marginated, red-brown pigmentation with fine telangiectasia, small, pale, slightly scaly, follicular papules, and patchy alopecia of vellus hair. The histologic features, although nondiagnostic, correlate well with the clinical features. The possible relationship to keratosis pilaris rouge is discussed.
