We report a case of primary squamous cell carcinoma in a gastric remnant. A 70-year-old man undergoing surgery for early gastric cancer on December 2002 was found to have signet-ring cell carcinoma, m, n1. Endoscopic examination, on January 2004 showed an elevated lesion-like SMT in the greater curvature of the gastric remnant, diagnosed as squamous cell carcinoma from a biopsied specimen. The patient had no other lesions in the lung, head, neck, or esophagus. We conducted total gastrectomy with splenectomy. Histopathologically, the tumor was diagnosed as moderately differentiated squamous cell carcinoma, mp, INFβ, ly0, v0, n0, without any adenocarcinoma component. No continuity was seen between the tumor and esophageal mucosa. From these findings, the tumor, yielding a definitive diagnosis of primary squamous cell carcinoma arising in the gastric remnant. The patient was discharged 21 days postoperatively and remains recurrence-free as of this writing. Primary squamous cell carcinoma of the stomach is rare and, including our case, 41 cases of primary squamous cell carcinoma of the stomach have been reported in the Japanese literature. Our case is, to our knowledge, the first case reported arising from a gastric remnant.
