Periumbilical perforating pseudoxanthoma elasticum is an acquired disorder of the elastic tissue found most frequently in multiparous women. A case of this condition is reported for a 74 year-old woman (G10, P10) showing yellow, reticulated plaque with erithematous and keratotic papules. Histology shows reticular dermis with irregular basophilic conjunctive fibers, as well as epidermal hyperplasia and elastic fibers elimination through keratotic channels.
