Abstract

An 80-year-old man was diagnosed with a gastric cancer by an upper gastrointestinal endoscopy. Immunostaining of the biopsy specimen revealed a small cell carcinoma. Distal gastrectomy with D2 lymph node dissection was performed. Histopathological examination showed a gastric small cell carcinoma in conjunction with squamous cell carcinoma ; pTypeO-IIa+ IIc, 25 mm, pT2 (MP), ly3, v3, pN1, pStage II. A small cell carcinoma is difficult to diagnose preoperatively by usual biopsy. This case may suggest that immunostaning of the biopsy specimen could allow us to diagnose a small cell carcinoma of the stomach preoperatively.Gastroenterological Endoscopy
