Background: The incidence of Kaposi's sarcoma (KS) in Sudanese renal transplant recipients is not known.
Methods: We retrospectively assessed the prevalence of KS in 30 Sudanese renal transplant recipients followed for 16 years.
Results: Four patients (13.3%) developed KS within 4-36 months after transplantation. All patients were HIV negative.
Conclusions: The incidence of KS in Sudanese renal transplant recipients is very high, supporting the theory of racial or geographic factors in its genesis.
