ASYNCHRONOUS BILATERAL NON-HODGKINS-LYMPHOMA OF THE TESTIS - REPORT OF 3 CASES

According t o the Working Formulation, all cases were classified as large cell imm unoblastic lymphomas, and immunohistochemical studies demonstrated a T -cell phenotype in 1 patient and a B-cell phenotype in 2 patients. Rel apse to the contralateral testis occurred after a mean interval of 6 m onths. The negative prognostic impact of these neoplasms is confirmed in the present series, since 2 patients died of disease 7 and 9 months after diagnosis and 1 patient had a laterocervical and Waldeyer's rin g recurrence after 1 year.
