Pyoderma Gangrenosum-associated Granulomatosis with Polyangitis: A Case Report and Literature Review.

Granulomatosis with polyangitis, formerly known as Wegener's granulomatosis, is a multi-system vasculitis that has a variable clinical presentation. Although uncommon, cutaneous symptoms can be the initial presenting symptom of granulomatosis with polyangitis. We present an unusual case of pyoderma gangrenosum followed by a diagnosis of granulomatosis with polyangitis. We also provide a review of current literature on therapeutic options.
