Forty-one patients with primary Kaposis' sarcoma (KS) have been evaluated clinically, histologically and immunologically at the time of diagnosis. There was no correlation between histological and immunological features. Moreover, the disease did not appear to be related to particular HLA phenotypes. The T4/T8 ratio was augmented. Leu 7+ cells were also significantly increased. The last 15 patients who received chemotherapy were recently reevaluated after treatment and an increase in B lymphocytes was observed. We also observed that spindle-shaped cells (SSC), which appear later in the histopathological course of the disease, disappear first during chemotherapy, concomitantly with the increase in B cells. We conclude that the course of the disease appears to be controlled by the host's immune response, though there is no clear correlation between histological and immunological evolution. Several immunological features differentiating it from AIDS associated KS have been found.
