Hormographiella aspergillata: an emerging mould in acute leukaemia patients?

P>We describe three invasive mould infections due to Hormographiella aspergillata occurring within 1 year in patients undergoing treatment for acute leukaemia. All patients presented with pulmonary infiltrates; one patient additionally had cerebral and ocular involvement. Diagnostic procedures included bronchoalveolar lavage in all, and video-assisted thoracoscopic surgery in two patients. Susceptibility testing was performed by E-test and detected low minimal inhibitory concentrations for voriconazole and amphotericin B. All patients received systemic antifungal therapy; however, all of them died. Despite this cluster of three cases of an unusual mould infection, no hospital source was detected.
