LINFOMAS PRIMARIOS EN EL SISTEMA NERVIOSO CENTRAL. CARACTERÍSTICAS CLÍNICO PATOLÓGICAS EN 10 PACIENTES VENEZOLANOS

SUMMARY We reviewed the clinic and pathological characteristics In 10 Venezuelan patients with primary central nervous system lymphomas. Eight were females and two males, with ages between 6 and 76 years (median of 45.6). The frontal lobes and the cerebellum were the most frequent sites of presentation; with space occupying lesions in the tomographic and angiographic studies. Histologically, all the cases were diffuse non-Hodgkin lymphomas, with a predominance of the ones with the large cells. We analyzed the immunophenotypical and genotypic findings which allow its identification and differentiation.
