A case of reactive perforating collagenosis accompanied by scabies and diabetes

Reactive perforating collagenosis (RPC) is characterized by hyperkeratotic papules and histopathologically transepidermal elimination of structural altered collagen fibers. It is often associated with diabetes mellitus and renal failure. Superficial skin trauma is thought to play a role in triggering the disease. In this article, we present a rare case of a 59-year-old woman with complaint of itching and scabs for 2 months. The patient diagnosed with scabies and RPC treated with 5% permethrin. After scabies treatment, the symptoms and clinical findings of RPC were successfully checked.
