Pyoderma gangrenosum (PG) is a rare inflammatory and ulcerative skin disease of unknown etiology characterized by neutrophilic infiltration of the dermis, mainly affecting the lower extremities. Bullous PG is a rare variant of this disease, usually associated with hematologic disorders. Here, we report a case of pathergy-positive bullous PG with subungual involvement associated with ulcerative colitis.
