Abstract

Porokeratosis are disorders of keratinization, characterized histologically by a parakeratotic column, the cornoid lamellae, and clinically by a distinct peripheral ridge. Porokeratosis usually occurs on the trunk or extremities, and facial lesions are rare. Follicular involvement, identified by follicular localization of cornoid lamellae, is uncommon and described only in association with disseminated superficial actinic porokeratosis (DSAP) and porokeratosis Mibelli (PM). A 34-Year-old woman is presented with asymptomatic 1 cm plaque lesion with hyperkeratotic ridge and depressed center on her nose since three years. Histopathological examination of a biopsy revealed cornoid lamellae confined exclusively to the follicle.
