Primary lymphoma of mucosa associated lymphoid tissue (MALT) in the parotid gland.
Malignant lymphoma of the parotid gland is a rare condition. In a series of 365 malignant lymphomas of the head and neck seven cases (1.9%) presented with a stage I/II MALT lymphoma of the parotid gland, originating from Mucosa Associated Lymphoid Tissue (MALT) and exhibiting the histological criteria of a centrocyte-like cell proliferation, surrounding reactive B-cell follicles. There were six men and one woman with a mean age of 50.1 years. In four patients the parotid mass was present for more than one year. Complete remission was obtained by radiotherapy (40 Gy). Prognosis for this group was found to be favourable with a follow-up ranging from 1.5 to 10 years.
