Morphological and immunohistological study of testicular lymphomas.
We have studied normal testis, seminomas and malignant lymphomas of the testis using routine stains and a panel of antibodies directed against lymphoid and basement membrane antigens. The results show that normal testis contains, at most, a minor population of T-lymphocytes: seminomas contain mixed T- and B-cell populations with a predominance of B-lymphocytes; and most primary lymphomas are B-cell tumours of large centroblastic type. Solid testicular lymphomas presenting secondarily to acute lymphoblastic leukaemias showed intact seminiferous tubular basement membranes with predominantly interstitial lymphomatous infiltrates, whereas the tubules in primary cases were over-run by lymphoma cells and basement membranes were disrupted.
