Erythromelanosis follicularis faciei et colli: case reports of bilateral lesions in 2 females.

Erythromelanosis follicularis faciei et colli (EFFC) is a rare disorder of unknown etiology characterized by the clinical triad of well-demarcated erythema, hyperpigmentation, and follicular plugging on the face. For many years, it was thought to be a disease occurring in males with ethnical cutaneous pigmentation. There are less than 50 cases reported in the literature, most of which are males. We describe bilateral EFFC in 2 females.
