Abstract
BACKGROUND
Mucosa-associated lymphoid tissue (MALT) lymphoma, a type of non-Hodgkin lymphoma, originates in the mucosal lining of body organs and internal cavities, including the nose, mouth, lungs, and digestive tract. The lymphoma develops when the body produces abnormal B lymphocytes. These lymphomas develop at the edge of the lymphoid tissue, called the marginal zone, and, hence, are classified as a type of marginal zone lymphomas. They are the most common type of marginal zone lymphomas although their occurrence is rare. To date, no previous cases of MALT lymphoma in the buccal fat pad have been reported.
CASE SUMMARY
We report the case of a patient who presented with a mass on the frontal cheek. Magnetic resonance imaging revealed a tumor in the buccal fat pad, and histopathological and immunohistochemical findings confirmed the diagnosis of MALT lymphoma. The patient had a history of Helicobacter pylori and hepatitis C virus infection, suggesting an association between these infective agents and MALT lymphoma.
CONCLUSION
Consideration of MALT lymphoma is essential in the differential diagnosis of frontal cheek masses.
Core Tip: Mucosa-associated lymphoid tissue (MALT) lymphoma mostly originates from the stomach, although it can originate from other mucosal-lined organs and internal cavities as well. Many cases have suggested a strong association between a history of Helicobacter pylori (H. pylori) infection and the development of gastric MALT lymphoma. In the present study, a patient with a history of H. pylori infection developed a buccal fat pad mass. Upon investigation, it was determined to be a case of extragastric MALT lymphoma. Hence, the role of H. pylori infection in the development of extragastric MALT lymphoma should be considered.
