Pustular Pyoderma Gangrenosum Associated with Ulcerative Colitis / 대한피부과학회지

Pyoderma gangrenosum (PG) is a rare and painful skin disease, frequently associated with underlying systemic conditions, such as inflammatory bowel disease or hematological malignancy. PG is generally classified into 4 types: classic (ulcerative), bullous, pustular, and vegetative. Pustular PG is an uncommon variant of PG that the pustules do not progress to form ulcers. We report a case of pustular PG, which was successfully treated with infliximab and topical tacrolimus, in a 28 year-old Korean man with ulcerative colitis.
