Uncommon assotiation of pyoderma gangrenosum and pemphigus vulgaris: a case report and diagnostic challenge

Abstract

Pyoderma gangrenosum (PG) is a rare, non-infectious neutrophilic dermatosis that typically presents as painful skin ulcers, most commonly affecting middle-aged women. While its exact pathogenesis remains unclear, it is often associated with systemic diseases. We see reports about idiopathic cases and drug-induced variants, too. However, PG associated with autoimmune blistering disorders such as pemphigus vulgaris is a highly uncommon phenomenon and has not been pre-viously recorded.
