Wegener's granulomatosis presenting as pyoderma gangrenosum

Abstract

We report three cases of Wegener's granulomatosis presenting with cutaneous ulceration resembling pyoderma gangrenosum. Wegener's granulomatosis classically affects the upper and lower respiratory tracts and the kidneys. Skin involvement occurs in up to 50% of patients. Increased awareness that cutaneous involvement can take the form of pyoderma gangrenosum and that it can be a presenting sign may lead to more rapid diagnosis of Wegener's granulomatosis.
