Summary:Mucosa-associated lymphoid tissue (MALT) lymphoma is a subtype of non-Hodgkin lymphoma, often affecting the parotid glands in Sjögren syndrome (SS). MALT lymphoma is an indolent disease frequently located in mucosal or nonmucosal extranodal sites. A 63-year-old woman complained of a nodular growth near her ear. Upon palpation, a nodular mass was observed in proximity to the anterior lobe of the left parotid gland. She reported dry mouth feeling lasting 2 years, hoarseness, dryness of the eyes and vaginal mucosa, tiredness, and body pain. Parotid ultrasonography and magnetic resonance imaging, minor salivary gland biopsy, and ophthalmologic evaluation were obtained. After 2 inconclusive ultrasound-guided needle biopsies, the lesion was removed by partial parotidectomy. Immunohistochemical analysis showed B-cell MALT lymphoma in the parotid gland, associated with SS. The patient was referred to a hematology oncologic center for evaluation and follow-up was established every 6 months.
