title: Periumbilical and periareolar perforating pseudoxanthoma elasticum.
abstract: The periumbilical perforating pseudoxanthoma elasticum or perforating calcific elastosis is a rare disorder and its pathogenesis is associated with the alteration of elastic fibers, which may probably result from trauma. We present the case of a 70-year-old woman with long-time blackish maculas and keratotic surface papules on the periareolar and periumbilical regions. The histopathological examination revealed altered elastic fibers, replete with calcium and formation of a path in the dermis with elastic fibers degraded in their interior, confirming the clinical diagnosis.
