The rare coexistence of gastric and esophagus squamous cell carcinoma: a case report.

Squamous cell carcinoma (SCC) of the stomach is a rare entity with fewer than 100 cases of primary SCC reported in the literature, while esophageal SCC is prevalent and more common. However, a synchronous squamous cell carcinoma found in the esophagus and stomach remains very uncommon. We present the case of a 64-year-old with a history of dysphagia who had an endoscopy that showed an impassable stenosis of the middle esophagus, with histopathology in favor of an esophagus squamous cell carcinoma.
