Summary

Mucosa-associated lymphoid tissue (MALT) is vital for host immunological surveillance against pathogens. MALT lymphoma, also known as extranodal marginal zone B cell lymphoma, is a non-Hodgkin’s lymphoma subtype that predominantly arises in the gastrointestinal tract. Chronic Helicobacter pylori (H. pylori) infection is a common cause of gastric MALT lymphoma, although other infections are reported in association with extragastric MALT lymphomas. To our knowledge, here we report the first case of synchronous MALT lymphomas of the colon and stomach in the presence of Strongyloides stercoralis and H. pylori infections that resolved after eradication of both organisms.
