Multiple Gastric Metastases from Ovarian Carcinoma Diagnosed by Endoscopic Ultrasound with Fine Needle Aspiration

Abstract

Metastasis to the stomach from nongastric tumors is a rare event. We present a case of ovarian cancer metastasis to the gastric wall that presented as multiple subepithelial gastric lesions. A 55-year-old female with known stage III b serous ovarian cancer was admitted to the hospital with melena and anemia. A 1.5 to 2 cm subepithelial mass with superficial overlying erosion in the antrum was seen in Esophagogastroduodenoscopy (EGD). Initial endoscopic mucosal biopsies were normal. An Endoscopic Ultrasound (EUS) was performed, which revealed two subepithelial lesions with the typical appearance of a gastrointestinal stromal tumor. Fine needle aspiration (FNA) of both masses revealed papillary adenocarcinoma from an ovarian papillary serous adenocarcinoma. This is the first reported case of multiple gastric metastatic lesions from ovarian cancer diagnosed by EUS FNA.
