Several fungi can cause eumycetoma, [5] including: Madurella mycetomatis, Madurella grisea, Curvularia lunata, Scedosporium species, Acremonium and Fusarium species. [2] Diagnosis is by biopsy, visualising the fungi under the microscope and culture. [5] Medical imaging may reveal extent of bone involvement. [4]
Most eumycetoma is caused by M. mycetomatis, whereas most actinomycetoma is caused by N. brasiliensis, S. somaliensis, A. madurae, and Actinomadura pelletieri. [1] People who develop mycetoma likely have a weakened immune system. [1] It can take between 3 months to 50 years from the time of infection to first seeking healthcare advice. [1]

Subcutaneous types include eumycetoma and chromoblastomycosis, which generally affect tissues in and beneath the skin. [1] [7] Systemic fungal infections are more serious and include cryptococcosis, histoplasmosis, pneumocystis pneumonia, aspergillosis and mucormycosis. [3] Signs and symptoms range widely. [3]
Mycetoma is a broad term which includes actinomycetoma and eumycetoma under it. However, eumycetoma is caused by fungal infection in contrast to actinomycetoma that is caused by mostly anaerobic bacteria.
In the United States, P. boydii is the most common causal agent of eumycetoma, and tends to be more common in men than in women, particularly in the 20- to 45-year-old age group. [10] In the United States, the incidence of infection by S. apiospermum between 1993 and 1998 was 0.82 per 100,000 patient-inpatient days; this figure increased to 1. ...
Colonies of Madurella grisea are slow growing, dark, leathery, and folded with radial grooves and with a light brown to greyish surface mycelium. With age, colonies become dark- to reddish-brown and acquire a brownish-black reverse.
An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration ...
