Abstract
Renal transplant recipients who received immunosuporessive agent are in high risk of development Kaposi's sarcoma. In Korea a few report of Kaposi's sarcoma has been pubilshed but any report of intrathoracic Kaposi's sarcoma provedn by open lung biopsy has not been pulbilshed until now. We report a case of intrathoracic Kaposi's sarcoma developed in a 25 year old Korean man, who had been operated renal transplantation due to end stage renal disease and received cyclosporine and prednisolone as immunosuppessive agent, without any other organ involvment and was proven by open lung biopsy. Although discontinuation of immunosuppressive agent, temporary symptomatic and radilolgic improvement were observed, he died 11 days later after open lung biopsy because of intractable resiratory failure.
