Abstract
We describe herein the case of a 73-year-old woman who developed a giant leiomyosarcoma in the remnant stomach 4 years after undergoing a distal gastrectomy for gastric carcinoma. Abdominal ultrasonography and computed tomography revealed a huge tumor, 22 cm in maximum diameter, in the left hypochondrial region. Selective abdominal angiography showed a hypervascular tumor fed by the branches of the splenic artery and left inferior phrenic artery. The tumor arose from the posterior wall of the remnant stomach, and demonstrated marked extragastric growth and direct invasion of the pancreas, transverse colon, and diaphragm on the left side. Total resection of the remnant stomach with en bloc resection of these adjacent organs was subsequently carried out. We reviewed the Japanese literature on this extremely rare tumor and evaluated its clinical profile. In comparison with leiomyosarcoma of the unresected stomach, that of the remnant stomach more frequently showed endogastric-type growth and was accompanied by ulceration of the gastric mucosa. The prognosis of patients with leiomyosarcoma of the remnant stomach appears to be gratly affected by the presence of liver metastases and the tumor diameter, similar to that of patients with leiomyosarcoma of the unresected stomach.
