Chromoblastomycosis.

Chromoblastomycosis is a chronic, subcutaneous mycosis, characterized by verrucous nodular lesions, usually involving the legs and mainly caused by Fonsecaea, Phialophora, and Cladophialophora spp. The characteristic finding on direct examination or biopsy specimen is the presence of fumagoid cells or Medlar bodies. Chromoblastomycosis can be refractory to medical treatment. Therapeutic options include oral itraconazole, terbinafine, or 5-fluocytosine, alone or combined with surgery or cryosurgery.
