A RARE CASE OF GENITAL POROKERATOSIS

Abstract

Porokeratosis is a keratinization disorder of unknownetiology. It is characterized by well defined annular plaques with central scarring or pigmentation and raised keratotic border. Disseminated superficial actinic porokeratosis, linear porokeratosis, porokeratosispalmaris et plantaris ,punctateporokeratosis are different clinical variants. Keratotic border is microscopically characterized by a column of parakeratotic cells invaginating the epidermis known as cornoid lamella which is a characteristic finding. Porokeratosis localized to the genital region is very rare. These lesions are mostly asymptomatic but there can be occasional pruritus. It mostly occurs on the scrotum followed by penis however adjoining areas like thighs, buttocks, natal cleft can also be involved. There are very few reports in Indian literature of porokeratsis limited to the genital region.
