Abstract
A Case of repeated massive bleeding from leiomyoblastoma of the stomach is reported. A 60-year-old man was referred to our hospital because of massive bleeding from submucosal tumor of the stomach. Endoscopically hen's egg sized gastric submucosal tumor was found in the lesser curvature of the antrum and bleeding was found from small holes in the tumor.
We performed partial gastrectomy. A 12×6×5cm size tumor exsisted in the lesser curvature of the antrum and developed exogastric space. Lymphonode swelling and remote metastasis was not found. The tumor was solid combined with partially blood-clot change and had septa. Histologically it was made up of round or polygonal cells. The each nucleus was surrounded by eosinophilic cytoplasma and by a peripheral clear halo.
It is generally accepted the majority of leiomyoblastomas have a benign clinical course. The clinical and pathophysiological characteristics including 160 cases reported in Japan were reviewed.
