[Pseudolymphoma in patients with primary Sjogren's syndrome].

: Sjogren's syndrome is an inflammatory autoimmune disease affecting primarily the exocrine glands. In the abscence of other autoimmune diseases it is classified as primary Sjogren's syndrome. Patients with primary syndrome have about 40 times higher relative risk of developing lymphoma then normal population, which offers a possibility to study malignant transformation's mechanisms in these patients. In the study we report a case of a woman with pseudolymphoma. The clinical diagnose used to be based on symptoms of proliferate disease, quetionnable histological evaluation and good response to steroids. Nowadays, applying advanced molecular techniques make it possible to diagnose lymphoma in labial salivary biopsy much earlier. It allows recognizing an incipient lymphoma in a group of patients with primary Sjogren's syndrome. Therefore so-called pseudolymphoma can usually be diagnosed as either benign or malignant lymphoproliferative lesions.
