Abstract

Primary lymphomas of the salivary glands are rare. It is estimated that they constitute no more than 5% of all lymphomas in different locations. The most common subtype developing in parotid glands is marginal zone B-cell mucosa associated lymphoid tissue type lymphoma (MALT) that belongs to a group of low-grade tumours. There are many factors associated with the incidence of that proliferative process: environmental and infectious agents as well as immune deficiency states. We describe a case of primary non-Hodgkin's lymphoma of the parotid gland arising in the background of previously undiagnosed and untreated Sjögren's syndrome in a 52-year-old woman. The article concerns a short review of the literature regarding etiology, symptoms, treatment and survival prognosis in that rare disease as well. MALT lymphomas should always be considered in the differential diagnosis of the tumors and swelling of the parotid gland area. A special, regular monitoring should include all patients with Sjögren's syndrome as those with the proven greater risk of developing that proliferative disease. The role of the laryngologist in the case of MALT-type lymphoma of the parotid gland should focus on a diagnosis and possible tumor cytoreduction with maximal saving of the facial nerve. The essential treatment of this pathology is one of the oncologists and haematologists.
