    Kaposi Sarcoma of the Ureter After Liver Transplant: Case Report and Literature Review
    (Başkent Üniversitesi, 2012-02) Chen, Yu; He, Xiao-shun; Qiu, Shao-peng; Zhao, Liang
    Kaposi sarcoma after an organ transplant is rare and infrequently involves internal organs. There are 2 reported cases in the English literature of Kaposi sarcoma originating from the transplant ureter after kidney transplant. We report a case of Kaposi sarcoma that occurred in the native ureter of the liver transplant recipient. Initially, the patient refused any further investigation and management and 2 years subsequent, had to undergo a left radical nephroureterectomy owing to the loss of renal function and distending pain. He recovered very well and no recurrence was detected at 47 months’ follow-up. To our knowledge, it is the first report in English. We review the literature on this topic and explore the therapeutic principles and histologic features of this sarcoma.

    Mucormycosis Extending From the Surgical Wound to the Transplanted Kidney: Case Report and Literature Review
    (Başkent Üniversitesi, 2012-08) Zhao, Liang; Liu, Long-shan; Chen, Yu; Wang, Wenwei; Tu, Xiang-an; Zhang, Ling; Wang, Chang-xi
    Mucormycosis is an opportunistic, life-threatening infection in organ transplant recipients. We report a case of surgical wound mucormycosis that extended to a transplanted kidney. The patient was a 59-year-old man who underwent a donation-after-cardiac-death kidney transplant 10 years after receiving a liver transplant. On day 10 after the kidney transplant, he presented with cutaneous and subcutaneous tissues necrotizing at his right lower abdominal surgical wound. The necrotic tissue biopsy and laboratory culture showed different causes, while a polymerase chain reaction quickly identified the causative fungus at the species level. Although the combination therapy consisted of immunosuppressant withdrawal, intravenous Liposome AmB, and aggressive surgical debridement; unfortunately, the cutaneous mucormycosis invaded his transplanted kidney, and the patient was given a graft nephrectomy and subsequent hemodialysis. We review the literature and conclude that mucormycosis in organ transplant recipients is a rare and extremely severe complication. Polymerase chain reaction provides a rapid and accurate diagnostic technique for species identification. Early effective antifungal therapy combined with aggressive surgical intervention and judicious withdrawal of immunosuppressants appears to be indispensable for a favorable outcome.
