Abstract

|
Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is a low- grade B-cell lymphoma that typically follows an indolent clinical course. It occurs in a variety of mucosal linings extranodal tissue, most commonly in the stomach. Other commonly involved sites include other parts of the gastrointestinal tract, thyroid, salivary gland, lung, lacrimal gland, synovium, dura mater, breast, skin, and eyes. It occurs very rarely in the buccal mucosa. A 50-year-old man came to the clinic while presenting a 5-month history of right- sided buccal mass. The incisional biopsy did not confirm the diagnosis of the lesion. He underwent complete excision of buccal mass for the diagnosis and treatment. The final pathology confirmed MALT lymphoma immunohistochemically. After surgery, he received radiotherapy with 30.6 Gy. There is no recurrence for 8 months after treatment. Herein we report a rare case of buccal MALT lymphoma with a review of the literature.
