their families. It has been reported since 1840. Noteworthy, the diagnosis of mycetoma in non-endemic or low endemic areas as Europe and North Africa is challenging. Physicians in these areas are usually unfamiliar with the disease-specific manifestations and need to exercise extra vigilance regarding those patients who are at high risk of contracting mycetoma infections. Recent evidence suggests that Egypt, which borders sub-Saharan Africa, is a low-endemic country. Additionally, recent evidence suggests that Pakistan, which borders India, is a moderate-endemic country. Unlike bacterial acute hematogenous osteomyelitis and septic arthritis, misdiagnosed or delayed diagnosis of mycetoma osteomyelitis can result in amputation or radical resection. The disease is listed by the

Affected people will experience massive swelling and hardening of the area, in addition to skin rupture and the formation of sinus tracts that discharge pus and grains filled with organisms. In many instances, the underlying bone is affected. Some people with mycetoma will not experience pain or discomfort, while others will report itching and/or pain. 255:. Since the bacterial form and the fungal form of mycetoma infection of the foot share similar clinical and radiological features, diagnosis can be a challenge. Magnetic resonance imaging is a very valuable diagnostic tool. However, its results should be closely correlated with the clinical, laboratory and pathological findings. 843: 162:
While most cases of mycetoma 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

Mycetoma is endemic in some regions of the tropics and subtropics. India, sub-Saharan Africa as Sudan, and Mexico are most affected. Pakistan is probably a moderate-endemic country. Sporadic cases have been reported across some North African countries. Egypt is probably a low-endemic country.
