Post-transplantation cutaneous and renal Aspergillus infection.

ABSTRACT

A renal transplant recipient aged 68 years experienced multiple complications after an initial good graft function from a deceased donor transplant. Late in the first week, the patient was oliguric with hematuria; the graft failed in week 2 after the development of a hematoma from a rupture of a renal artery aneurysm. He had a recurrent bleed from the internal iliac graft site and subsequently developed painful dark patches on his leg, distal to where the transplant had been. Histology from the explanted graft and skin biopsies demonstrated Aspergillus flavus; this was also grown in the culture of the external iliac artery tissue. Systemic aspergillosis is rare but well recognized, especially in the immunocompromised. Presentations include mycotic aneurysms and secondary cutaneous aspergillosis from hematogenous spread. Diagnosis requires confirmation by histology or direct culture, but a high ß-glucan concentration and positive galactomannan antigen can suggest invasive fungal infection in the early stages of the disease. Cases should be managed with systemic antifungals and involvement of local microbiology services; unfortunately, the prognosis is poor.
