By Gary M. White, MD Porokeratotic eccrine ostial and dermal duct nevus

Linear lesion on the side of the foot of a teenager.

The porokeratotic eccrine ostial and dermal duct nevus (PEODDN) is a rare nevoid condition characterized by asymptomatic grouped papules and plaques, often linear, of keratotic papules and comedone-like pits.


Surgical excision may be considered for small and localized lesions in appropriate anatomical locations. CO2 laser was found to be effective in a few cases.
