A 84-year-old woman was referred to our hospital to find out the cause of weight loss. A computed tomography showed multiple enlarged lymph nodes, the mass near by the lesser curvature of the stomach and the mass of right hepatic robe. We couldn't identify the primary cancer. The mass near by the gastric lesser curvature was suspected to be an enlarged metastatic lymph node, and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed for pathological diagnosis. Based on clinicopathological and immunohistochemical features of the tumor, it was diagnosed with high-grade serous carcinoma, and estimated ovarian origin. In women, we should consider the possibility of the gynecological tumors as a differentiation of cancer of unknown primary origin. EUS-FNA is useful for making histological diagnosis.
