a chronic fungal disease of man that affects the skin and is mainly prevalent in areas of the world with a hot climate. The causative agent is a fungus of the genus Hormodendron that grows on plants and in the soil. Infection occurs when the fungus penetrates injured skin; as a rule, the skin of the legs is affected. Reddish nodules and then deep inflammatory infiltrates covered with crusts and wartlike growths appear at the site of penetration. When the growths slough off, ulcerations with a seropurulent discharge are exposed.
Chromomycosis persists for years and gradually spreads to adjacent areas of the skin; other organs and systems are rarely affected. The disease is treated with amphotericin B or iodine preparations, or by surgical means. Chromomycosis may be prevented by applying a disinfectant to injured skin.
