Primary Squamous Cell Carcinoma of Stomach: A Rare Presentation

Abstract

Primary gastric squamous cell carcinoma is a very rare presentation. Its pathogenesis is obscure, and the treatment strategy is largely unknown and controversial. We report a case of primary squamous cell carcinoma of the stomach with liver metastases in a 66-year-old man. The patient presented with a 2-month history of abdominal pain, vomiting, hematemesis, and weight loss. Endoscopic examination revealed large ulceroproliferative growth in body of stomach. Integrated PET CT (positron emission tomography computed tomography) scan revealed metabolically active nodular wall thickening involving body of stomach with liver metastases. Multiple biopsies of the lesions revealed squamous cell carcinoma of the stomach. The patient was started on palliative chemotherapy and is presently in partial response to treatment. He is tolerating treatment with no major side effects.
