Recurrent malignant schwannoma of the small bowel.

Primary malignant schwannoma of the small bowel is an extremely rare disease. Only 24 malignant schwannomas of the small bowel have been reported in the medical English literature. We report a primary malignant schwannoma of the distal ileum in a 53-year-old woman, who was admitted to the hospital because of abdominal pain. CT scan revealed a semisolid mass in the small intestine of the serosa. The tumour measuring 14 x 13 x 8 cm and 100 cm of the distal ileum were resected. We observed a recurrence after seventeen months and the recurrent tumour measured 6 x 2.5 x 1 cm was excised.
