ABSTRACT

BACKGROUND

Nevi are visible, circumscribed, long-lasting lesions of the skin reflecting genetic mosaicism.[1] Porokeratotic Eccrine Ostial and Dermal Ductal Nevus (PEODDN) is believed to be a congenital hamartoma of possible eccrine origin with no malignant potential.[2] It is a rare variant of porokeratosis having characteristic feature of cornoid lamella on histopathology. It is a disorder of keratinisation involving the intraepidermal eccrine duct (acrosyringium) and is characterised by eccrine hamartoma and cornoid lamella in pathology.[3] It is usually localised at the single extremity, while wider systematised distribution has been documented rarely. Till now, a few cases have been reported. Here, we are reporting 2 cases of this rare entity with one having childhood origin and other having adult onset.
