Papular elastorrhexis. report of five cases.

Papular elastorrhexis is a rare disorder that occurs predominantly during adolescence. We report 5 patients with asymptomatic white, nonfollicular, firm papules scattered over the trunk and extremities. Histologically, the papules demonstrate focal areas of collagen homogenization with decreased and fragmented elastic fibers. The clinical differential diagnosis includes papular acne scars, dermatofibrosis lenticularis disseminata (Buschke-Ollendorff syndrome), cutaneous collagenoma and nevus anelasticus, but histology clearly separates papular elastorrhexis from the other entities.
