    Abstract:
    In patients with hematological malignancies invasive mycoses occur frequently. In this retrospective study autopsy and histopathology material of 171 patients with hematological malignancy who had died between 1994 and 1996 at the 1st Department of Internal Medicine (Hematology), St. László Hospital, Budapest was analysed. In cases with invasive fungal infection post mortem results were compared to clinical and microbiological data. Through the three years' period an invasive mycosis could be confirmed in 33 patients by autopsy. Aspergillosis occurred in 21, candidiasis in 11, other fungal infections in 2 cases, a double infection was seen in 1 patient. The incidence was 19.2% (in invasive candidiasis: 6.4%, in aspergillosis 12.2%). Invasive aspergillosis most frequently was seen in the lung (71%), while candidiasis occurred mainly in the intestinal tract (42%). Cultures for mycology were collected from the autopsy material of 9 patients, of which 8 gave positive results. A previous fungal colonisation results was confirmed in 23 patients, but based on colonisation conclusions rarely could be driven concerning the species causing invasive infection. Sensitivity of Aspergillus antigen and antibody tests was 45 and 50%, respectively. Predisposing factors for invasive aspergillosis and candidiasis were similar, except for duration of neutropenia (24 vs. 12 days, p < 0.004). The antifungal drug most frequently used was amphotericin B. We observed a persisting infection in invasive pulmonary aspergillosis and chronic disseminated candidiasis in spite of the administration of a cumulative dosis of 1-2 g. Most frequently Aspergillus infections--primarily that of the lung--can be seen. Presence of invasive mycoses can usually be confirmed in vivo, but an early diagnosis still remains unsolved.
