GASTRIC COLLISION TUMOUR PRIMARY GASTRIC ADENOCARCINOMA AND PRIMARY GASTRIC EXTRANODAL MARGINAL ZONE (MALT) LYMPHOMA

We report a case of a 61 year old male with a gastric collision tumor consisting of a primary gastric adenocarcinoma and a primary gastric extranodal marginal zone (MALT) lymphoma. The association of adenocarcinoma with a MALT lymphoma synchronously has been reported extensively however a collision tumour is extremely rare with no case reports from India. These cases are difficult to diagnose preoperatively and pathological identification of the dual components is often the only method of diagnosis.
