Abstract:
A subepidermal calcified nodule occurred on the face of a 15-year-old Negro boy. Histological examination revealed its apparent origin in mature and immature hair follicles. Previous reports suggest that subepidermal calcified nodules may arise in nevi or in sweat glands. An additional finding in this case was transepidermal elimination of calcium.
