Abstract

Porokeratotic eccrine ostial and dermal duct nevus (PEODDN) is a rare benign eccrine nevoid hamartoma with only a few cases reported till date. It is characterized by asymptomatic or mildly pruritic pitted comedone-like papules on palms or soles and keratotic papules and plaques in a linear pattern on the extremities, usually present in childhood. We present here three interesting cases of the same. Diagnosis was confirmed by histopathology which showed parakeratotic columns overlying mature eccrine sweat glands in dermis and dyskeratotic cells of lower epidermis.
