Antibiotics may be the only treatment needed if a follow-up biopsy shows that the infection has cleared and there is no evidence of lymphoma. Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT), also known as MALT lymphoma, arises from malignant transformation of B cells from the marginal zone of MALT ().The gastrointestinal tract is the most common site of involvement in MALT lymphoma, with the stomach being the most common primary site (2, 3). Gastric MALT lymphoma is a rare type of non-Hodgkin lymphoma that is characterized by the slow multiplication of B lymphocytes, a type of immune cell, in the stomach lining.

Patients present with abdominal pain, dyspepsia, and, rarely, gastric outlet obstruction. MALT lymphomas arise at a wide range of different extranodal sites, with the highest frequency in the stomach, followed by lung, ocular adnexa, and thyroid, and with a low . Mucosa-associated lymphoid tissue (MALT) lymphoma is categorized as indolent or low-grade B-cell lymphoma; however, high-grade histologic transformation can occur. MALT lymphoma clinical manifestation and endoscopic appearance Gastric MALT lymphoma is often an indolent, multifocal disease and because of that, it has a high rate of relapse after surgical excision. It can cause abdominal pain, diarrhea, gastrointestinal tract bleeding, and swollen stomach.
