Successful Treatment of Conjunctival Kaposi Sarcoma in a Human Immunodeficiency Virus-Negative Kidney Transplant Recipient: A Case Report.

Kaposi sarcoma (KS) is the most common tumor in patients with human immunodeficiency virus (HIV), and its frequency is increasing after organ transplantation in HIV-negative patients. A 28-year-old woman had preemptive kidney transplantation from her 48-year-old mother. In the postoperative ninth month, an exophytic mass was found in the upper medial conjunctiva of the right eye. The lesion was excised under local anesthesia, and cryotherapy was applied to the surgical area. The biopsy result was reported as KS. Treatment with tacrolimus was switched to everolimus (EVO), but EVO was discontinued because of pneumonitis. The patient was followed without any recurrences after the excision of the conjunctival lesion. No local or systemic recurrence was observed in the 14th month after surgical excision and local cryotherapy. Local treatment and the reduction of immunosuppressive therapy may be effective in the treatment of conjunctival KS.
