Overview
Diagnostic Criteria
Diagnosis for phycomycosis is through a biopsy or culture, although an ELISA test has been developed for Pythium insidiosum in animals.[1] As swabs of tissue or discharge are generally unreliable, the diagnosis of mucormycosis tends to be established by a biopsy specimen of the involved tissue. Computerised imaging techniques such as MRIs, CT scans and X-rays may be useful in the diagnosis of specific areas.
Diagnosis for basidiobolomycosis is by laboratory culture of the organism, usually from pieces of tissue taken from the patient. It grows easily on most media, but risks being discarded as irrelevant or being reported as a contaminant because laboratory staff are unfamiliar with it.
Diagnosis is often difficult because basidiobolomycosis is a rare disease and therefore often not recognised. The lesions often look like tumours rather than infection, so often no sample is sent for microbiology, however, the histopathology is characteristic: the Splendore-Hoeppli phenomenon describes the presence of fungal hyphae (which may exist only as ghosts on the slide) surrounded by eosinophilic material.
