[Primary non-Hodgkin lymphoma of the parotid gland: Revision of 8 cases]

The manifestation of non-Hodgkin lymphoma as a primary parotid tumour account for 5% of all tumours at this location. We present 8 patients diagnosed and treated for parotid non-Hodgkin lymphoma in our hospital between 1996 and 2003. Of the cases, 62% were women who had an indurated mass for almost 4 months. A fine needle aspiration and computed tomography were performed on all patients. The immunohistochemical study provided us with the definitive diagnosis. Biopsy was done in all cases. The treatment was chemotherapy in 75% cases and surgery in 25%. The objective was to analyse the clinical and pathological patterns, plus the different treatment modalities and prognoses, which characterise this type of pathology based on the analysis of our patients and compared with those reported in the literature.
