Unravelling the enigma: A rare case of primary gastric squamous cell carcinoma with aggressive metastasis

This report details a rare case of squamous cell carcinoma (SCC) in the stomach, a condition accounting for only a fraction of gastric carcinomas. A 46-year-old male patient with dysphagia, abdominal pain, and haematemesis was diagnosed with primary gastric SCC displaying aggressive metastasis, an exceptionally low-incidence condition affecting mainly males in their sixth decade of life. Primary gastric SCC, though clinically similar to adenocarcinoma, involves a bleaker prognosis, lacking standardized treatment protocols. Histopathology and imaging confirmed the diagnosis, highlighting the challenges in managing advanced cases. Palliative chemotherapy showed partial remission but led to severe neuropathy. The case underscores the urgent need for research to understand the pathogenesis, effective management, and therapeutic targets for primary gastric SCC, emphasizing its scarcity and poor prognosis in medical literature. Increased clinical awareness and ongoing research are crucial for improving outcomes in such rare presentations.
