title: [Management of mycetoma in West-Africa].
abstract: Mycetoma is still endemic in the northern areas of West-Africa. This infection is more common in males, rural inhabitants, between 20 and 40 years of age. Mycetoma is generally easy to identify on clinical presentation, it is a chronic subcutaneous inflammatory tumor with discharging sinuses. The commonest affected site is the foot (70%), leg, knee, thigh, hand and arm are the most frequent extrapodal localizations. Diagnosis must be confirmed by the presence of grains at direct and histological examinations. It is indispensable to distinguish actinomycetoma (caused by aerobic bacteria) and eumycetoma (caused by fungi) as their treatments are different. The main etiological agents in West-Africa: Streptomyces somaliensis, Actinomadura pelletieri, Actinomadura madurae (actinomycetes), Madurella mycetomatis and Leptosphaeria sp (fungi) can be identified in most cases by histological examination of the grain. In the West Sahelian belt actinomycetoma is more frequent than eumycetoma except in Mauritania. When a mycetoma is diagnosed it is fundamental to determine as precisely as possible the extent of the lesion. Bone involvement is the major complication and must be systematically investigated by radiology. Mycetoma has characteristic ultrasonographic features, ultrasonographic technique appears to be very useful in medical centers where no mycological tests can be done. Ultrasonography is also an accurate technique to delimit the extent of the process. Computed tomography is also sensitive to assess the extent of mycetoma in soft tissues and can detect early bone involvement but is more onerous than ultrasonography. Ketoconazole or itraconazole in combination with surgery is recommended for eumycetoma patients. Actinomycetoma responds to antibacterial agents, different therapeutic schemes can be proposed and depend on the etiological agent.
