Fatal primary cutaneous aspergillosis in a bone marrow transplant recipient: nosocomial acquisition in a laminar-air flow room

Abstract

A case of primary cutaneous aspergillosis occurring in an allogeneic bone marrow transplant recipient in a laminar airflow room is reported. The patient developed grade III graft-versus-host-disease and epidermolysis. Although the patient had remained in his laminar airflow room from the graft onward, he subsequently developed primary cutaneous aspergillosis. The aspergillosis became invasive and the patient died. The patient was probably contaminated by air containing conidia when he left the sterile room for endoscopy, and the fluidized bed used may have contributed to the local development of the disease. This nosocomial aspergillosis stresses the necessity of performing invasive procedures under laminar airflow protection to prevent Aspergillus contamination in immunocompromised hosts at risk for aspergillosis.
