This chronic fungal infection of the skin usually appears on the lower extremities after a minor puncture wound. After years, the lesions may become large wart-like masses, and lymphatic stasis may ensue. [CCDM, p. 117-8] The five type of lesions described are nodular, tumorous, verrucous, plaque, and cicatricial. Secondary lesions may be spread by scratching or, rarely, by dissemination through lymphatic vessels. [ID, p. 2260] The most common fungal agents are Fonsecaea pedrosoi, Cladophialophora carrionii, and Phialophora verrucosa. Response to treatment with anti-fungal drugs may be frustrating. Barefooted, outdoor laborers are commonly affected. The lesion progresses from a papule, to a red or purplish plaque, to a scaly or verrucous plaque, and finally to a verrucous nodule.
