Metastatic Small Cell Carcinoma of the Stomach

Abstract

Primary gastric small cell carcinoma (GSCC) is an extremely rare type of small cell carcinoma. Its aggressive nature with early widespread metastasis and late detection gives it a poor prognosis with overall survival of <12 months. GSCC is a type of neuroendocrine tumor, and because of its histopathological similarity to small cell lung carcinoma (SCLC), treatment regimen of GSCC includes the same chemotherapy agents as SCLC. We report a case of a 57-year-old man who presented with signs of partial gastrointestinal obstruction and was found to have a primary stage IV GSCC with metastasis to the liver.
