Leiomyoblastoma, which shows caracteristic pathological features among myogenic tumors, is observed in the uterus as in the whole area of the gastroistestinal tract including the stomach. We recently experienced a case of leiomyoblastoma of the duodenum and here discuss the case with reference to 12 cases previously reported in Japan. A 14-year-old girl with a chief complaint of vomiting was referred to our hospital for further evaluation of an abdominal mass. Upper gastrointestinal X-ray showed a giant tumor on the third portion of the duodenum. A metastatic tumor was recognized in the liver on CT-scan. Duodenectomy was performed. Histology of resected specimen showed Leiomyoblastoma. In the Japanese literature Leiomyoblastoma of the duodemum is rare and has had a greater tendency to be malignant than leiomyoblastoma of the stomach. In our case, the tumor originated in the duodenum and metastatic tumor was observed in the liver. Therefore we considered she should be kept under close medical observation.
