A case of malignant lymphoma diagnosed with spontaneous tumor perforation

Abstract

We report a rare case of primary gastric lymphoma with spontaneous perforation. A 67-year-old woman was admitted to our hospital with a complaint of abdominal pain. Abdominal computed tomography revealed free air and ascites around the stomach. We conducted an emergency surgery and found a 10 mm perforation in the lesser curvature of the lower portion of the stomach. In addition, a hard mass was attached to the perforated area. We thought this was a gastric tumor and performed distal subtotal gastrectomy. The resected tumor measured 8.5 × 6.0 mm in size. Pathohistological diagnosis was malignant lymphoma of diffuse large B-cell type. The patient was administered adjuvant chemotherapy (CHOP) after the operation. The patient showed good recovery with no signs of recurrence.
