Primary squamous cell carcinoma of the stomach in a seventeen-year-old boy.

Primary squamous cell carcinoma (SCC) of the stomach is extremely rare and thought to arise from ectopic squamous epithelium, which in turn could either result from the squamous metaplasia of the gastric mucosa or be congenital in origin. We report herein a case of SCC of the stomach in a 17-year-old male, who died 1 year after undergoing a gastrectomy. To our knowledge, this is the youngest case of primary SCC of the stomach reported in the literature. Further speculative possibilities of the development of primary gastric SCC are discussed following the presentation of this case.
