 A 73-year-old man underwent UGI(upper gastrointestinal)endoscopy during follow-up for gastric ESD(endoscopic submucosal dissection). The results revealed a light reddish, depressed 6-mm-diameter lesion on the lesser curvature of the upper gastric body.

 Histological examination of the biopsy specimen revealed a tubular adenocarcinoma in the membrane ; immunostaining revealed the small variant cells between the crypts to be positive for chromogranin A and synaptophysin. Thus, the diagnosis was an endocrine carcinoma of the stomach. The clinical diagnosis was early gastric cancer(type 0-IIc with the depth of invasion estimated as M), and thus, the patient underwent ESD. The final pathological diagnosis was an endocrine carcinoma with a tubular adenocarcinoma, 6×4mm extension, type 0-IIc, pT1b2(pSM2 600μm), ly(+), v(−), HM0, and VM0. Additional surgical resection was performed, and no tumor or lymph node metastasis was observed.
