Primary squamous cell carcinoma (SCC) may originate elsewhere in the body, including the head, neck, lung, bronchus, cervix uteri, esophagus and cardia, and metastasize to the stomach. In the present report, a case is presented of an SCC, which arose from an unknown primary site and metastasized to the stomach of a 59-year-old male. The tumor was located in the interspace between the liver and the stomach. It involved the placenta percreta, lamina muscularis and submucosa, however, had already metastasized to a regional lymph node at the time of surgery. No SCC was observed in other organs on physical examination, which included positron emission tomography-computed tomography. In the follow-up period, there was no evidence of additional malignant tumors in the patient; therefore, the origin of the tumor was speculative. To the best of our knowledge, this is the first case report regarding a tumor of this type.
原发性鳞状细胞癌（SCC）可能起源于身体的其他部位，包括头部、颈部、肺、支气管、子宫颈、食管和贲门，并转移至胃。在本报告中，呈现了一例SCC病例，该病例起源于未知的原发部位并转移至一名59岁男性的胃。肿瘤位于肝脏和胃之间的间隙。它累及穿透性胎盘、肌层和黏膜下层，然而，在手术时已转移至区域淋巴结。体格检查（包括正电子发射断层扫描 - 计算机断层扫描）未在其他器官发现SCC。在随访期间，患者没有额外恶性肿瘤的证据；因此，肿瘤的起源具有推测性。据我们所知，这是关于此类肿瘤的首例病例报告。
