Gastric metastases. An endoscopic series of ten cases

We report a series of ten cases of the clinical, endoscopic and pathological features of gastric metastases. Patients were six women and four men between 54 and 88 years old, with gastric metastases from breast carcinoma (4), lung carcinoma (4) and melanoma (2). Patients underwent an upper gastrointestinal endoscopy for epigastralgia (2), hematemesis (2), dysphagia (1) and anemia (5). On endoscopy, tumors appeared as nodules with a central ulceration (5), an ulceration (4) or simulating linitis plastica (1). Metastases were located in the cardia (2), fundus (5) and antrum (3). Primary tumors had been diagnosed between one day and 20 years before upper endoscopy. Eight patients had multivisceral metastases. The microscopic features of the gastric metastases resembled a primary gastric cancer in eight cases. Thanks to clinical data, the pathologist confirmed the diagnosis of gastric metastases on immunohistochemistry. Nine patients died in the eight-month follow-up period. Gastric metastases are rare, occur at a late stage of the neoplastic disease, and have a poor prognosis. Diagnosis of gastric metastases is difficult because they simulate primary gastric cancer on endoscopy and on microscopic examination. A correct diagnosis is based on good communication between gastroenterologists and pathologists.
