Arterial occlusion mimicking vasculitis in a patient with incontinentia pigmenti

A large number of diseases can mimic a vasculitis. The diagnosis can be challenging due to the similarity with several diseases that have a different pathogenesis. As reported in the literature, incontinentia pigmenti (IP), a rare genetic disorder, can present vascular alterations on eye, brain and lung. We report a case of peripheral arterial disease in a patient with IP, suggesting further vascular localizations of the disease.
