Abstract

Mucosa-associated lymphoid tissue (MALT) lymphoma has specific clinical and pathologic features. The most common site MALT lymphomas is the stomach; however, it can also occur in other organs, such as the salivary glands. MALT lymphoma is rare, but its prognosis is good. A 32-year-old man visited Konyang university hospital with parotid mass. Superficial partial parotidectomy was performed to exclude lymphoid neoplasms. IgH gene rearrangement analysis of the surgical specimen led to the diagnosis of MALT lymphoma. The patient underwent esophagogastroduodenoscopy, positron emission tomography-computed tomography, and whole-body bone scan. Regional or distant metastasis was not observed on staging workup. The patient underwent postoperative radiation therapy, there has been no recurrence of MALT lymphoma to date. Here, we report this rare case of parotid MALT lymphoma that was treated with surgery and postoperative radiation therapy.
