Solitary Benign Ulcer of the Colon in Childhood

An 8-year-old Negro girl presented with rectal bleeding and abdominal pain. On barium enema examination, a lesion with the appearance of an ulcer crater was identified in the descending colon. Follow-up studies over a four-month period showed complete healing. Similar lesions in adults are usually diagnosed at surgery because of perforation. The etiology of this lesion is unknown.
