A rare case of gastric cancer coexisted with a primary malignant lymphoma of the stomach is reported.
An 83-year-old woman was referred to the hospital because of a gastric cancer in the antrum at another hospital. She visited complaining of abdominal pain. After admission, endoscopic examination revealed a Borrmann-2 like lesion in the lesser curvature of the antrum. She underwent distal gastrectomy. In the resected specimen, the Borrmann-2 like lesion with a early gastric carcinoma type III like lesion in the antrum was found. Histopathologically, the Borrmann-2 like lesion was poorly differentiated adenocarcinoma with the invasion depth of sm, and the type III like lesion which was posterior wall of the carcinoma showed proliferation of atypical lymphocytes. On immunohistochemical stains, the atypical lymphocytes were positive for L-26 which was antibody for B-cells.
We should not only focus on the main lesion, but also observe another lesion in the endoscopic examination.
