[A Case of Perforated Gastric MALT Lymphoma with Total Gastrectomy].

A 62-year-old man presented with complaints of acute abdominal pain. Abdominal enhanced CT showed free air in the abdominal cavity, a thickened stomach wall accompanied by deep ulcer, and enlarged lymph nodes around the stomach. Emergent surgery was conducted, and a perforation in the upper part of the stomach was found. Total gastrectomy was performed. On pathological examination, a mucosa-associated lymphoid tissue lymphoma was diagnosed. Histologic examination revealed the absence of Helicobacter pylori in the gastric mucosa. After the operation, adjuvant chemotherapy was not administered. However, he has been well for 11 months without any recurrence. Gastric MALT lymphoma with spontaneous perforation is considered extremely rare. A brief review of the literature is presented.
