Abstract
We report a very rare case of small cell carcinoma of the stomach. A 73-year-old man, complaining of an epigastric mass, was admitted to our hospital for close examination. An Endoscopic approach revealed a Borrmann type 3 tumor at the antrum of the stomach, subsequently partial gastrectomy was performed with following findings (P0H0N4 (+) S3, in Stage IV, and non-curative B resection. Histological final diagnosis was small cell carcinoma of the stomach with findings of intermed., IFN-γ, ly3, v1, n4 (+), aw+ and ow-. Although the immunochemotherapy was attempted to, abdominal wall invasion from the rapidly growing residual carcinoma of the duodenal stump, obstructive jaundice and liver metastases were found two after months operation. Twenty cases of small cell carcinoma of the stomach which can be categorized into the ectopic hormone-producing tumors, have been reported in Japan. The prognosis of this disease is very poor resulting from rapidly developing metastases and invasion in an early phase of the disease.
