Winer's dilated pore
A hair structure anomaly that appears as an enlarged solitary comedo, most commonly on the face, predominantly on the upper lip, cheek, or forehead of a middle-aged person. The lesion can also be found on the trunk, most commonly the back. The pore is a tumor of the intraepidermal follicle and infundibulum of a pilosebaceous apparatus. The skin surrounding the pore appears to be unchanged, with no inflammation or induration.
