Pyoderma gangrenosum (PG) is an uncommon & noninfectious neutrophilic dermatosis commonly associated with underlying systemic disease in more than 50% of cases. About 20-30% of cases are commenced and aggravated by minor trauma or surgery, a phenomenon named pathergy. PG is associated with many systemic diseases, but association with Takayasu's arteritis (TA) / pulseless disease, which is chronic inflammatory and stenotic disease of large sized arteries is less common. These conditions responded well with systemic corticosteroids. The association of PG with TA has been less reported in the literature so far.
