Abstract:
BACKGROUND: Reactive perforating collagenosis is one of the perforating disorders that are characterized by transepidermal elimination of dermal materials. It can be associated with systemic disease such as chronic renal disease and/or diabetes mellitus. OBJECTIVE: We wanted to investigate the clinical and histopathological features of reactive perforating collagenosis. METHODS: We reviewed the medical records, clinical photographs and histopathologic slides of 14 cases of reactive perforating collagenosis that were seen in our department. RESULTS: The most common clinical features were flesh-colored, dome-shaped papules with a keratinous plug. Residual scarring was seen from the previously healed lesions. Half of the patients had skin lesions on the whole body except the face, palm and sole. Most of the patients (79%) had at least one systemic disease. Chronic renal failure (21%) and diabetes mellitus (29%) were the most commonly associated conditions. The other associated conditions were hypertension, acute pyelonephritis, non-small cell lung cancer, herpes zoster, transplantation and non-Hodgkin lymphoma. Three of the cases (21%) were otherwise healthy. Most patients benefited from topical steroid and oral antihistamine when their disease was regressing. CONCLUSION: This study demonstrated the clinicopathologic features of reactive perforating collagenosis. It is frequently associated with diabetes mellitus and chronic renal failure, but this may also develop in patients with other systemic disorders, and also in those patients who are without any medical problems.
