Abstract
In terms of the literature, leiomyoma of the stomach with a diameter of more than 15 cm is designated as giant leiomyosarcoma. This disease is relatively rare. There were less than 100 cases including this case in the Japanese literature as far as we could review. Here such as case is described with a review of the literature. An 81-year-old man was admitted because of a left lateral abdominal tumor. On admission, an elastic-soft and infant's head-sized tumor ranging from the left lateral to upper abdomen was palpated. Abdominal CT and abdominal ultrasonography revealed a giant tumor with a diameter of 20 cm ranging from the upper to left lateral abdomen. Gastric endoscopy, enema, and abdominal angiography were added, but failed to offer preoperative definite diagnosis. On laparotomy the giant tumor was found only to connect with the middle part of the body of stomach. A diagnosis of submucosal tumor arising at the stomach was made. Subtotal gastrectomy with complete resection of the tumor was carried out. Resected tumor was 3, 100 g, 18×19×19 cm in size, and was diagnosed as gastric leiomyosarcoma histologically. There has been no recurrence up to now, 11 months after the operation.
