Pyoderma gangrenosum (PG) is rare, chronic, painful ulcerative skin disorder frequently associated with various systemic diseases. Clinical presentation in PG is generally classified into 4 types including ulcerative, bullous, pustular, and vegetative. The ulcerative type of PG is associated with inflammatory bowel disease such as ulcerative colitis, Crohn's disease, arthritis, and monoclonal gammanopathy. On the other hand the bullous type of PG is known to be associated with lymphoproliferative disorders. However it is rare for both types of bullous and ulcerative PG to occur simultaneously in the same patient. We report a rare case of PG showing bullous and ulcerative types that developed simultaneously on a 44-year-old Korean female patient with ulcerative colitis.
