Abstract

Transepidermal elimination is a spontaneously-developed phenomenon in certain skin disorders, in which altered connective tissue or foreign material is expelled via the epidermis to the exterior. We report a case of a 60-year-old man with a 1x1 cm sized, black-colored nodule, showing transepidermal elimination, on the right shin. Histological examination revealed a pigmented, epidermal cyst, containing deposition of pigment in its wall and cavity. To the best of our knowledge, no pigmented epidermal cysts have been reported in korea to date.
