<unk>  is a chronic infection in the skin caused by either bacteria (actinomycetoma) or fungi (eumycetoma), typically resulting in a triad of painless firm skin lumps, the formation of weeping sinuses, and a discharge that contains grains. 80% occur in feet. Most eumycetoma is caused by M.<unk> tis, whereas most actinomycetoma is caused by N. brasiliensis, S. somaliensis, A. madurae and Actinomadura pelletieri. People who develop<unk>  likely have a weakened immune system. It can take between 3 months to 50 years from time of infection to first seeking healthcare advice. Diagnosis requires ultrasound and fine needle aspiration. While most cases of<unk>  occur in Sudan, Venezuela, Mexico, and India, its true prevalence and incidence are not well-known. It appears most frequently in people living in rural areas, particularly in farmers and shepherds, who are often men between 20 and 40 years earning the primary incomes for their families. It has been reported since 1840. The disease is listed by the World Health Organization (WHO) as a neglected tropical disease.
