title: Eruptive collagenomas.
abstract: A 24-year-old woman presented with hypopigmented papules of the abdomen that had been present for four years without a family history of similar cutaneous findings or associated medical problems. Histopathologic features confirmed the diagnosis of a connective-tissue nevus that was composed of collagen. Eruptive collagenomas are a rare form of acquired collagenomas, which are characterized by the sudden appearance of asymptomatic papules and nodules on the lower trunk and extremities; the lesions are composed of haphazardly arranged collagen fibers. The pathogenesis is unknown, lesions are persistent, and therapeutic options have not been reported.
