Disseminated Cryptococcosis Involving Skin and Lung in an Immunocompromised Patient After Kidney Transplantation: A Case Report

Cryptococcus neoformans can cause detrimental cryptococcosis and other severe complications, especially in immunocompromised populations. Disseminated cryptococcosis in organ transplantation patients is extremely rare and often involves lungs, brains, skin, nails, and other organs. In this paper, we report a rare disseminated cryptococcosis case involving skin and lung that presented with recurrent dark brown abscesses and nodules in an immunocompromised female after kidney transplantation. The K-Set detection result of Cryptococcus capsular polysaccharide in serum is positive. The identification of pus culture by Autof MS 1000 indicates that the patient was infected with Cryptococcus neoformans var. grubii. In addition to treatment using liposomal amphotericin B, fluorocytosine, and fluconazole, local extraction of pus and simultaneous injection of liposomal amphotericin B into skin lesions were performed. This comprehensive treatment method proved effective, as the patient recovered from fever and skin symptoms. The innovative treatment may contribute to helping more disseminated cryptococcosis patients.
