Primary cutaneous cryptococcosis in a lung transplant recipient.
Cryptococcal skin lesions are found in 10 to 15% of patients with disseminated cryptococcosis. Primary skin inoculation by Cryptococcus neoformans is rare but has been reported. We report the first known case of primary cutaneous cryptococcosis in a lung transplant recipient. Our patient, a 57-year-old man, underwent left single-lung transplantation and presented with a nonhealing ulcer 50 months later. Skin histopathology and culture confirmed C. neoformans. Serum and cerebrospinal fluid cryptococcal antigen tests were negative. The lesion healed after treatment with fluconazole. To date, disseminated disease is not evident. Primary cutaneous cryptococcosis has been reported in kidney and liver recipients but not in lung transplantation recipients. Nonhealing ulcers in immunocompromised patients mandate aggressive diagnostic procedures. Differential diagnosis of these cutaneous lesions should consider fungi, including C. neoformans.
