A mycetoma is a tumorlike mass caused by several species of fungi that enter the body through wounds. This condition typically appears as a lump on the feet or legs beneath the skin, with a tract to the surface that drains granular material. The granules are white, yellow, or black, depending on the type of fungus involved. The condition resembles a chronic abscess that resists healing, despite prolonged treatment with antibiotics.
Treatment: Complete surgical removal is the treatment of choice. This is not always possible. Some of the newer antifungal drugs (such as ketoconazole and itraconazole) show promise in treating difficult cases. Treatment must be continued for at least two months beyond apparent cure.
