Exuberant squamous metaplasia of the gastric mucosa in a patient with gastric adenocarcinoma

BACKGROUND: The presence of squamous epithelium in the stomach is only occasionally encountered and is associated with prolonged mucosal injury. Squamous metaplasia in patients with cancer is relatively rare and only four cases have been reported in the stomach, all of which have been associated wit...

description BACKGROUND: The presence of squamous epithelium in the stomach is only occasionally encountered and is associated with prolonged mucosal injury. Squamous metaplasia in patients with cancer is relatively rare and only four cases have been reported in the stomach, all of which have been associated with squamous cell carcinomas. We present the first case of exuberant squamous metaplasia in a patient with gastric adenocarcinoma of the cardia. CASE PRESENTATION: A 56-year-old woman presented with epigastric pain and weight loss. Endoscopy showed an irregular depressed hyperemic lesion covered with a whitish plaque on the cardia. A total gastrectomy was performed and the tumor in the subcardia was found to extend up to the proximal stomach with diffuse squamous metaplasia in the surface of the tumor and proximal gastric mucosa in contiguity with the esophageal squamous epithelium. It is believed that the squamous extension from the esophagus to the proximal stomach and the gastric adenocarcinoma occurred at the same time. CONCLUSIONS: Synchronous squamous metaplasia and underlying adenocarcinoma in the stomach is extremely rare. Recognition of this entity would be beneficial for clinicians to avoid unnecessary treatment.
