A Case of Reactive Perforation Collagenosis

Reactive perforating collagenosis is a unique cutaneous disorder characterized clinically by recurrent, umbilicated, crusted papules arising in response to minor trauma. This disorder belongs to a group of dermatologic conditions that have been classified as "transepidermal elimination" syndrome.
