Abstract

Leiomyosarcomas of the stomach are unusual tumors, accounting for 1% to 3% of all malignant tumors and 17% to 20% of all smooth muscle tumors of the stomach. It is difficult to diagnosis these tumors preoperatively because of its vague symptoms and signs or producing symptoms only late. Despite their rarity and difficulty in diagnosis, thier diagnosis is important due to more favorable prognosis aasociated with these tumors than that of gastric carcinoma. Recently, endoscopy is being used with increasing frequency, but because these are submucosal lesions the diagnosis of thease tumors cannot be easily made through the endoscope. We experienced a case of relatively full-brown leiomyosarcoma in gastric fundus. Endoscopy showed 6x6cm sized, definite margined, protruding mass on gastric fundus, with central deep ulceration coated with blood clots. The mucosa overlying the mass was intact, smoothly effaced and the bridging fold was also visible. Postoperative ultrasound showed large protruding mixed echogenic solid mass with contral deep excavation due to ulcer, and intact serosa, so suggestive of endogastric tumor. We believed endoscopy combined with endoscopic ultrasound is probably useful method in early diagnosis of gastric submucosal tumors, especially exogastric type or early small tumors
