ABSTRACT

We describe the case of a 21-year-old man with an 8-year history of porokeratotic eccrine ostial and dermal duct naevus (PEODDN) of late onset. The patient had pruritic, keratotic papules on the dorsal surface of his left hand, bilaterally on his palms and multiple yellowish lesions on the plantar surface of his feet. On histopathological examination cornoid lamella-like parakeratotic columns above eccrine sweat ducts were observed. The acrosyringium was also dilated. The lesions were refractory to treatment with salicylic acid in petrolatum and acitretin for 2 months. This entity should be taken into consideration in the differential diagnosis of linear keratotic cutaneous eruptions.
