PG - 269-274 LID - 10.11406/rinketsu.59.269 [doi] AB - A 73-year-old man with left parotid gland swelling over 2 months was referred to our hospital in March 201X. Purpura on the lower legs had been recurrent for >20 years. Biopsy of the parotid gland demonstrated diffuse infiltration of abnormal lymphocytes that were negative for CD10 and positive for CD19, CD20, and kappa-chain. The Ki-67 positivity was <10%; lymphoepithelial lesions were observed. The patient was diagnosed with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). Chromosome analysis revealed t (X;14) (p11.2;q32), and fluorescence in situ hybridization (FISH) of metaphase spreads showed three signals of the immunoglobulin heavy chain (IGH) gene on the derivative chromosomes X and 14, besides the normal chromosome 14. CT findings of parotid glands were suggestive of Sjogren syndrome, and biopsy of the purpura on the leg demonstrated leukocytoclastic vasculitis. In the literature, only seven patients with lymphoma and t (X;14) translocation have been reported. Of these, five patients had MALT lymphoma, one had nodal marginal zone lymphoma, and one had diffuse large B-cell lymphoma. In all patients, lymphoma evolved from previous autoimmune diseases. It is suggested that MALT lymphoma with the t (X;14) translocation forms a new entity of lymphoma.
