title: A case of small cell carcinoma of the stomach.
abstract: A case of small cell carcinoma of the stomach is reported. A 53-year-old male was referred to our hospital for elective surgery for gastric cancer. Pre-operative examinations revealed no metastases. Gastrectomy was performed curatively, and there were no gross findings of metastases. Histologically, the tumor was composed of intermediate-sized cells with hyper-chromatic nuclei and scanty cytoplasm. These cells were argyrophilic and positive for chromogranin A. A small portion of the tumor consisted of conventional adenocarcinoma (signet ring cell carcinoma and tubular adenocarcinoma). No lymph node metastasis was observed microscopically. However, 7 months after the operation, splenic and hepatic metastases were detected, and the patient died very soon thereafter. Small cell carcinoma of the stomach is a very rare disease. In literature, only 15 cases have been cured surgically. Among them, only one case had been diagnosed as small cell carcinoma before the operation, which suggests the difficulty of pre-operative diagnosis. The prognosis of this disease is very poor compared with the common type of gastric carcinoma. Considering the poor prognosis of this particular disease, adjuvant chemotherapy might be mandatory in all cases even if surgically curative resection is performed.
