Kaposi's sarcoma in renal transplant patients: experience at the Cruces Hospital in Bilbao.

Background: Kaposi's sarcoma (KS) in renal transplant recipients (RTRs) probably arises from a complex interplay of multiple factors.

Objective: In order to analyze the prevalence of KS in patients transplanted at the Cruces Hospital in Bilbao, together with their clinical features, treatment, and etiologic factors, we performed a study using the registry of RTRs in our center.

Methods: The records of 1,230 kidney transplant patients at the Cruces Hospital between 1979 and 1998 were reviewed.
