Abstract

Primary gastric squamous cell carcinoma (PGSCC) is an extremely rare cause of gastric malignancy. We present a 66-year-old man with a past medical history of stage I left palpebral marginal zone lymphoma status post radiation. The patient was complaining of a two-year history of bloating and early satiety. An upper endoscopy was performed, showing a 2.5 cm polypoid lesion at proximal corpus; however, the cardia and esophagus were normal. Biopsies were positive for gastric squamous cell carcinoma. He underwent partial gastrectomy and was referred to oncology for treatment. In 2011, the Japanese Gastric Cancer Association proposed diagnostic criteria for the diagnosis of PGSCC. The clinical presentation of this malignancy does not differentiate from that of other types of gastric tumors. We report this case to highlight squamous cell carcinoma as a cause of primary gastric cancer. Gastroenterologists should be aware of this entity to facilitate prompt referral to specialized centers, where surgical resection can be done.
