Primary MALT Lymphoma of the Parotid Gland.

Only 1-2% of salivary gland tumors are malignant lymphomas, and malignant lymphomas are rare among the parotid tumors. A 58-year-old female complained of anteroauricular swelling. Flowcytometric examination of the biopsy specimen revealed MALT (mucosa-associated lymphoid tissue) lymphoma. Superficial parotidectomy and upper neck dissection were performed, and involvement of one superficial cervical lymph node was found. After the operation, subcutaneous swelling of the forearm was excised, which was revealed to be associated with the lymphoma. We performed three courses of CHOP therapy after the operation. Eight months post operatively, no recurrence has been detected.
