A usually benign skin disease most commonly occurring on the face, around the eyelids and on the scalp. The lesions form firm, flesh-coloured, translucent papules with slight surface telangiectasia; small lesions may coalesce to form a solid sheet tumor. They usually appear near puberty and become stationary after enlarging for several years. Regression and, rarely, malignant degeneration may occur. Etiology unknown. A familial disease transmitted as an autosomal dominant trait. The small scalp lesions have been called Ancell-Spiegler's tumours, the lesions affecting especially nasolabial area Brooke-Fordyce trichoepitheliomas.
