A stercoraceous ulcer of the colon in neglected Hirschsprung's disease.

A large, nonspecific, chronic ulcer was found in the sigmoid colon of a 13-year-old child with neglected, undiagnosed Hirschsprung's disease (HD). There is no known association between HD and colonic ulcers, suggesting that the ulcer was a true stercoraceous ulcer of the colon and not an intrinsic defect of the aganglionotic bowel.
