We reported a case of gastric leiomyoblastoma which grow in size during 2 years and 7 months and was diagnosed before resection.
A 26-year-old female, complaining of tarry stool and dizziness, visited our hospital in June 1989. The upper GI series and endoscopic examination revealed a submucosal tumor, 35×30 mm in size, on the posterior wall of middle gastric body. Although we could not diagnosed by biopsy, the tumor was suspected of malignancy and we recommended the patient resection of tumor, but she rejected.
In April 1992, the tumor enlarged 45×40 mm in size and formed an ulceration on the surface of tumor. By endoscopic biopsy and color Doppler-endoscopic ultrasonography (CD-EUS) guide tunnel biopsy from the ulcerated area of tumor we diagnosed the tumor as leiomyoblastoma of the stomach. Subtotal gastrectomy and lymphnode resection were performed. No metastasis to liver or dissemination to peritoneum were found, but a single lymphnode metastasis was observed.
CD-EUS guide tunnel biopsy is a useful method in diagnosis of the submucosal tumor of stomach, because we can obtain tumor tissues safely and certainly without bleeding or perforation. We consider that radical operation is necessary to gastric leiomyoblastoma, since it has a malignant potential and occasionally metastasize.
