Pseudoxanthoma elasticum with periumbilical perforation in a nullipara

Pseudoxanthoma elasticum (PXE) is an inherited multisystem disorder that primarily affects the skin and is characterized by progressive calcification and degeneration of the elastic fibers. PXE has recently been found to be caused by mutations in the ATP-binding cassette transporter C6 (ABCC6) or the multidrug resistance-associated protein 6 (MRP6) genes. Perforating PXE is a rare presentation that is usually seen in the periumbilical area in obese multiparous black women; it has distinct clinical and histopathological features and there may or may not be systemic manifestations. We report an unusual case of PXE in a nulliparous woman, with perforation in the periumbilical area and without any systemic involvement.
