Overview

An established criteria exists which can help in diagnosing mucormycosis. The criteria is provided by the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group. It is based on microscopic findings, clinical criteria and characteristics of the fungus.

Diagnostic Criteria[1][2]

Mucormycosis may be diagnosed using the definitions and criteria provided by the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group. It classifies invasive fungal infection as:

  • Proven invasive fungal disease except endemic mycosis
  • Probable invasive fungal disease except endemic mycosis
  • Criteria for diagnosis of endemic mycosis

Criteria for proven invasive fungal disease except for endemic mycoses

Analysis and specimen Molds Yeasts
Microscopic analysis Histopathologic, cytopathologic, or direct microscopic examination of a specimen obtained by needle aspiration or biopsy, in which hyphae or melanized yeast-like forms are seen accompanied by evidence of associated tissue damage Histopathologic, cytopathologic, or direct microscopic examination of a specimen obtained by needle aspiration or biopsy from a normally sterile site (other than mucous membranes) showing yeast cells—for example, Cryptococcus species indicated by encapsulated budding yeasts or Candida species showing pseudohyphae or true hyphae
Sterile material Recovery of a mold or “black yeast” by culture of a specimen obtained by a sterile procedure from a normally sterile and clinically or radiologically abnormal site consistent with an infectious disease process, excluding bronchoalveolar lavage fluid, a cranial sinus cavity specimen, and urine Recovery of a yeast by culture of a sample obtained by a sterile procedure (including a freshly placed [<24 h ago] drain) from a normally sterile site showing a clinical or radiological abnormality consistent with an infectious disease process
Blood Blood culture that yields a mold (e.g., Fusarium species) in the context of a compatible infectious disease process Blood culture that yields yeast (e.g., Cryptococcus or Candida species) or yeast-like fungi (e.g., Trichosporon species)
Serological analysis: CSF Not applicable Cryptococcal antigen in CSF indicates disseminated cryptococcosis

Criteria for probable invasive fungal disease except for endemic mycoses

Host factors:

  • Recent history of neutropenia (<0.5 × 109 neutrophils/L [<500 neutrophils/mm3] for >10 days) temporally related to the onset of fungal disease.

Clinical criteria

  • Imaging showing sinusitis plus at least 1 of the following 3 signs:
  1. Acute localized pain (including pain radiating to the eye).
  2. Nasal ulcer with black eschar.
  3. Extension from the paranasal sinus across bony barriers, including into the orbit.
  • 1 of the following 2 signs:
  1. Focal lesions on imaging.
  2. Meningeal enhancement on MRI or CT.
  1. Small, target-like abscesses (bull's-eye lesions) in liver or spleen.
  2. Progressive retinal exudates on ophthalmologic examination.

Mycological criteria

  1. Presence of fungal elements indicating a mold.
  2. Recovery by culture of a mold (e.g., Aspergillus, Fusarium, Zygomycetes, or Scedosporium species).

Invasive fungal disease other than cryptococcosis and zygomycoses.

    • β-d-glucan detected in serum

Criteria for proven endemic mycosis

  • In a host with an illness consistent with an endemic mycosis, 1 of the following:
  1. Recovery in culture from a specimen obtained from the affected site or from blood.
  2. Histopathologic or direct microscopic demonstration of appropriate morphologic forms with a truly distinctive appearance characteristic of dimorphic fungi, such as Coccidioides species spherules, Blastomyces dermatitidis thick-walled broad-based budding yeasts, Paracoccidioides brasiliensis multiple budding yeast cells, and, in the case of histoplasmosis, the presence of characteristic intracellular yeast forms in a phagocyte in a peripheral blood smear or in tissue macrophages.

Probable endemic mycosis
