Abstract

An 86-year-old woman visited our hospital with the chief complaint of vomiting. Upper gastrointestinal endoscopic examination showed the giant ulcer confinement tumor-type lesion in the greater curvature of the lower body and fornix in the stomach, and showed a he low elevated flat-type lesion in the lesser curvature of the middle body in the stomach. Histological examination by endoscopy revealed poorly-differentiated adenocarcinoma from the lesion of the lesser curvature of the middle body in the stomach. Samples from the greater curvature of the lower body and fornix in the stomach were assessed to be necrotic tissue. Endoscopic examination and pathological examination indicated multiple advanced gastric cancer and early gastric cancer. The patient underwent a total gastrectomy. The resected tumors were assessed to be type 0-I + IIc in the lesser curvature of the middle body and type 2 in the greater curvature of the lower body and fornix. Histological results indicated signet-ring cell carcinoma of type 0-IIa + IIc and malignant lymphoma of type 2. Although malignant lymphoma could not have been diagnosed before the operation, we encountered a very rare case of the coexistence of early adenocarcinoma and malignant lymphoma in the stomach.
