Chromoblastomycosis is a subcutaneous infection caused by a number of different fungi such as Cladophialophora carrionii and
Fonsecaea pedrosoi; a less common cause is Phialophora dermatitidis. The infection starts in the subcutaneous tissue or dermis and this is followed by progressive enlargement of cutaneous plaques that are usually either verrucose or plaque-like with central scarring. The organisms can be found in skin scrapings or biopsies as small pigmented cells often divided by a cross wall.
