Abstract

A papilloma is a benign epithelial lesion characterized by finger-like projections of tissue lined by an overgrowth of squamous cells and a core of connective tissue. We report a case of squamous papilloma on the cardia in a 52-year-old asymptomatic female. Endoscopy showed a 1-cm sized is polyp with hyperemic change originating from the cardia adjacent to the esophagogastric junction, the biopsy of which suggested a diagnosis of squamous papilloma. Endoscopic mucosal resection was performed to obtain a definite diagnosis and the polyp was completely removed. The histological result was compatible with squamous papilloma, and its surrounding tissues showed foveolar epithelium, which suggested a stomach origin. This is the first report of endoscopic resection of a gastric squamous papilloma. Squamous papilloma should be considered in the differential diagnosis of a gastric polyp, especially one in the cardia. As the prognostic value of a squamous papilloma is not well known, we recommend endoscopic resection to treat a gastric squamous papilloma, when possible.
