Abstract:
Porokeratotic eccrine ostial and dermal duct nevus (PEODDN) is a rare, benign congenital hamartoma involving the eccrine sweat duct. Histologically, the distinctive feature of PEODDN is the existence of keratinous plugs that represent cornoid lamellae overlying dilated infundibula of eccrine ducts. Lesions are typically asymptomatic papules or plaques that are located on the distal extremities, including palms, fingers and soles. We report a case of a 7-year old girl with PEODDN who exhibited lesions on the left knee and the perianal region.
