•Solid organ transplantation is a well-recognized risk factor for aspergillosis.•Diagnosis is often challenging, especially in the comorbid patient.•Voriconazole is the first-line antifungal agent.•Prompt therapy and removal of infected tissue where possible are essential.•The prognosis for invasive Aspergillus is extremely poor. 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 β-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.
