We report a case of leiomyoblastoma of the jejunum in a 43-year-old man, who complained of melena, light abdominal pain, and an abdominal mass. He had experienced massive melena 2 times, 6 and 10 years ago. The mass was 17×13cm in size and X-ray examination showed a filling defect existing at the jejunum 4cm distal from the Treitz's ligament. Endoscopy confirmed its location and angiography showed hepatic metastasis. An operation was successfully performed. The resected specimen showed a necrotic polypoid tumor measuring 15.0×12.5×11.0cm, and partial perforation to the omentum.
Microscopic examination confirmed that the tumor was leiomyoblastoma. Leiomyoblastoma of the intestine is so rare compared to that of the stomach, as far as we could review, that only 27 oases including this case had been reported in Japan.
