A Rapidly Growing Gastric Squamous Cell Carcinoma Presenting as a Subepithelial Tumor

Abstract

Squamous cell carcinoma (SCC) of the stomach is a very rare disease, comprising less than 1% of all stomach cancers. Primary SCC of the stomach was first reported in 1895, and about 100 cases have been reported worldwide since then. Although there are several theories regarding its pathogenesis in the stomach, the process of development of SCC remains unclear. The prognosis of SCC of the stomach is poor compared to adenocarcinoma because it is often diagnosed at late stages and is more prone to lymphovascular invasion. We report a case of rapidly growing SCC of the stomach presenting as a subepithelial tumor on the cardia during screening endoscopy.
