[Reactive Perforating Collagenosis in Hemodialysis Patients]

Chronic Kidney Disease associated Pruritus (CKD-aP) in hemodialysis affects approximately 38% of our patients. It is not associated with any dermatological lesion other than the common scratching lesions, a consequence of the symptom itself. The causes associated with itching have been studied in various treatments. However, there is a relatively rare condition that involves 10% of hemodialysis patients, known as reactive perforating collagenosis. This is a pathological condition secondary to chronic hemodialysis therapy, where widespread itching develops, associated with a peculiar reactive dermatosis with perforation of the dermis and development of dermal-epidermal continuity solutions with extrusion of matrix components dermal. In this work we report our experience with a diagnosed case of this condition.
