This case report describes the presentation, workup, and management of a 73-year-old patient with multifocal extranodal mucosa-associated lymphoid tissue (MALT) lymphoma. The MALT lymphoma was identified through a process that began with routine fecal immunochemical testing, which is recommended in BC for screening averagerisk patients for colorectal cancer. The fecal immunochemical test (FIT) used for screening requires the patient to submit a stool sample collected at home using a simple kit. The sample is then analyzed for the presence of blood. However, because bleeding can occur with benign pathologies such as hemorrhoids, inflammatory bowel disease, and vascular lesions, further investigation is required when certain pathologies are found on colonoscopy done in the colon screening program. In this case, investigation included esophagograstroduodenoscopy and CT imaging. The results from all investigations eventually led to the detection of a rare gastric cancer. Despite the patient being from a part of the world with high rates of endemic Helicobacter pylori, the MALT lymphoma identified was not associated with H. pylori and was probably related to a systemic inflammatory disorder.
