title: Reactive Perforating Collagenosis.
abstract: TWO brothers aged 9 and 7 years had asymptomatic, umbilicated papules on their extremities, buttocks and hair-lin , since infancy. The lesions would heal spontaneously with atrophic scarring, but new lesions would keep appearing especially after trauma. Koebner phenomenon was observed on several body sites. Histopathology including Van-Geison's stain confirmed the lesions to be reactive perforating collagenosis. There was no evidence of diabetes, renal or heapatic disease.
