BRESSAN, Aline Lopes et al. Periumbilical and periareolar perforating pseudoxanthoma elasticum. An. Bras. Dermatol. [online]. 2010, vol.85, n.5, pp. 705-707. ISSN 0365-0596. http://dx.doi.org/10.1590/S0365-05962010000500018.
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.
