Kaposi sarcoma (KS) is a human herpesvirus-8-associated lymphoangioproliferative neoplasm. Both human and viral interleukin-6 (IL-6) proteins seem to drive much of the clinical manifestations of KS, which provides a new target for intervention by using IL-6-neutralizing antibodies. We describe the clinical course of a patient in whom tocilizumab, a monoclonal anti-IL-6 receptor antibody approved for rheumatoid arthritis (RA) treatment, was effective not only in inducing RA remission but was also safe for KS.
