| Disease Introduction Mechanism | Chromoblastomycosis is a human chronic subcutaneous infection, beginning after inoculation trauma, caused by several dematiaceous fungi. These fungi are found in the soil and in decomposing plant matter. It occurs world- wide, but is more frequently observed in tropical countries such as Brazil. This mycosis is caused by several species of dematiaceus hyphomycetes: Fonsecaea pedrosoi, Phialophora verrucosa, Cladophialophora carrionni, and Rinocladiella aquaspersa. Clinically, chromoblasto- mycosis is characterized by the slow development of polymorphic skin lesions (nodules, verrucas, plaques and scar tissue). Inside the host, infectious propagules adhere to epithelial cells and differentiate into sclerotic forms, which effectively resist destruction by host effector cells and allow the establishment of chronic disease. The disease is usually insidious and the lesions increase slowly but progressively, not responding to the usual treatments and quite often reappearing. |
