Abstract
We report a case of leiomyoblastoma of the mesocolon, together with a brief review of the literature. A 79-year-old female was admitted to the hospital because of an abdominal mass. Abdominal CT scanning revealed a giant tumor with septums in the upper abdomen. Abdominal angiography showed a tumor shadow fed by the middle colic artery with an early venous filling. Under a diagnosis of primary tumor arising in the transverse mesocolon, operation was performed. During operation a tumor, 15×15×12cm in size and 1, 430g in weight, was found in the transverse mesocolon, and the tumor was removed with partial resection of the mesocolon and omentum. Historogical diagnosis was leiomyoblastoma of the transverse mesocolon. She has been doing well for 3 years and 6 months after the operation without any metastasis or recurrence.
