A woman in her 50s with a history of Crohn disease (CD) was referred for evaluation of painful perianal skin growths. The growths had been present for 1 year. Physical examination revealed a tender perianal plaque with a papular, cobblestone-like surface (Figure, A). She was taking no medications and had not had active gastrointestinal symptoms of CD in several years. A biopsy specimen from the perianal plaque was obtained (Figure, B and C).
