Abstract
Mucosa-associated lymphoid tissue (MALT) lymphoma in the head and neck region, such as in the salivaly glands, thyroid gland and orbit, is relatively rare. We herein report a 66-year-old female case of MALT lymphoma arising from the bilateral superficial parotid glands. An MRI scan demonstrated well- defined lobulated masses in the bilateral superficial parotid glands. A left superficial parotidectomy was performed. The pathologis and immunohistochemical findings were consistent with MALT lymphoma. After surgery, radiotherapy was administered to the bilateral parotid glands at a total dose of 46Gy. In addition to the radiotherapy, one cycle of Cyclophosphamide, Pirarubicin, Vincristine and Methyl- prednisolone chemotherapy was performed. There has been no evidence of recurrence up to now. The prognosis of localized MALT lymphoma is usually favorable if the tumor can be treated with surgery and or radiotherapy. However, such cases require a careful follow-up.
