Gastric leiomyosarcoma growing outside the stomach wall was histologically diagnosed in a 64-year-old woman by means of a variety of examinations. The patient's chief complaint was a painless abdominal mass. Laparotomy revealed a 13.5×12.5×10.5 cm pedunculated tumor from the greater curvature to outside the stomach wall. No lymphatic metastasis was found, and wedge resection was performed. In the sixth postoperative year the patient noticed a mass in the left hypochondrium and returned to the hospital for examination. Similar examinations were conducted. Laparotomy was performed for recurrent gastric leiomyosarcoma in the greater omentum and mesocolon. The tumor had a diameter of 7 cm and was located next to the mesocolon. The tumor and the mesocolic anterior sheath were extirpated. Histopathologically, the gastric leiomyosarcoma was similar to that of the primary lesion. The suspected cause of recurrence was puncture aspiration, rather than tumor cell remnants in the local resected area or the detached area.
