Solid-organ transplant recipients are at higher risk of developing Kaposi sarcoma, which is a multicentric vascular neoplasm of lymphatic endothelium-derived cells. Reducing doses of immunosuppressive drugs and switching from calcineurin inhibitors to the mammalian target of rapamycin inhibitor rapamycin have been suggested as an effective first-line treatment modality in most patients. Herein, we report a 64-year-old renal transplant recipient who developed multiple cutaneous and visceral Kaposi sarcoma lesions 2 months after transplant. The patient showed no improvement, with progression of the disease until month 15 of the suggested therapy of rapamycin.
