ABSTRACT

Non-Hodgkin lymphoma is the most common primary testicular neoplasm of older men but is rare in young men. The vast majority of primary testicular lymphomas (PTL) are intermediate- to high-grade lymphomas. Objective: to describe the clinical, morphologic, and immunophenotypic characteristics of PTL seen in a referral center. Material and Methods: we reviewed the cases of PTL seen from 1986 to 1999. We obtained data of laboratory tests, clinical course, treatment, and immunohistochemical studies. Results: 10 patients with diagnosis of PTL were identified. Median age was 62.3 years (range 42-81 years), and nine patients underwent orchiectomy as initial therapeutic procedure. Other treatment modalities after diagnosis included combination chemotherapy (60%) and combination radiotherapy (20%). Histologically, testes showed diffuse dense infiltration of large lymphoma cells. All cases were classified as diffuse large cell lymphoma according to REAL classification. Eight cases were studied with use of paraffinsection immunoperoxidase, 7/8 tumors were B-lineage lymphomas, and one was a T-lineage lymphoma.
