BACKGROUND: The incidence of Kaposi's sarcoma (KS) in patients transplanted at the Organ Transplant Center of Catholic University in Rome appears to have increased in recent years. OBJECTIVE: To describe the clinical characteristics of KS in a group of transplant recipients. METHODS: Over 8 years, a total of 302 renal-transplant recipients were followed. When KS was suspected, histology and staging procedures were performed. RESULTS: Ten cases of KS have been diagnosed (8 males, 2 females; age 46.4 +/- 9.4 years); 4 of them were on triple therapy. All the patients were HIV-1 seronegative. The onset of KS occurred 3 months to 4 years after transplantation (21.1 +/- 17.6 months). The disease was limited to the skin in 6 cases and involved internal organs in the remaining 4. Four patients experienced complete remission of the disease following reduction of the immunosuppressive therapy. CONCLUSION: The high incidence of KS in this population (2.98%), as compared to that reported in other transplant patient groups, suggests that, besides viral infection, genetic predisposition may play a pathogenetic role. However, immunosuppression is the leading factor in transplant patients.
