Abstract

Gastric adenocarcinoma with enteroblastic differentiation (GAED) is rare and its clinicopathological characteristics are not well documented. However, reports indicate that it exhibits more aggressive characteristics, including lymph node metastasis or liver metastasis, than a conventional gastric adenocarcinoma. Herein, we report a case of GAED with rapid recurrence and disease progression. A 55-year-old male, diagnosed with gastric cancer (GC), demonstrated initial endoscopic findings suggestive of advanced GC. He underwent curative resection since there was no evidence of lymph node or distant metastases. The disease was reported as an early GC that was confined to the submucosal layer, without evidence of lymph node metastasis in the final pathological results. However, six months after surgery, multiple hepatic metastases were found during abdominal computed tomography; the pathological results were consistent with metastasis from the GC. Immunohistochemistry of the primary carcinoma pathological specimens showed positive results for alpha-fetoprotein and sal-like protein 4, suggesting enteroblastic differentiation, which is thought to be associated with rapid recurrence and disease progression.
