Case report. Pathohistological findings in a clinical case of disseminated infection with Fusarium oxysporum.

Abstract:

:Despite appropriate antimicrobial and antifungal therapy (amphotericin B), a disseminated infection with Fusarium oxysporum in a 75-year-old immunocompromised patient (acute myeloid leukaemia, minimal leucocyte count of 0.5 giga l-1) led rapidly to death. A similarly fatal course of an F. oxysporum infection has been reported in several cases. Fusarium oxysporum could be isolated shortly before death from blood cultures and from a swab taken from skin efflorescences. An autopsy revealed histopathologically typical fungal infiltrates in the mucosa of the pharynx, epiglottis, trachea, and oesophagus and in the parenchyma of the spleen, the lung and both kidneys. Because of the high risk of a fatal outcome of this infection, the clinician should aim at maximum diagnostic enforcement. We propose both analysis of blood cultures and immediate skin biopsy--with PAS-staining--of suspicious dermal efflorescences for microscopic examination. The treatment of choice is discussed controversially but a beneficial effect has been reported from granulocyte transfusion, subcutaneous administration of GM-CSF and concomitant treatment with amphotericin B.
