Adenocarcinoma of the jejunum in an 18-year-old patient: a case report.

The clinical history and surgical findings of an adenocarcinoma of the jejunum in an 18-year-old black man are recorded. The world literature on this subject has been reviewed, revealing a total of six cases of adenocarcinoma of the jejunum and ileum in patients under 20 years of age. This seventh case is recorded for its rarity and the findings which should alert the clinician: cramping abdominal pain, weight loss, and occult blood in the stool.
