Scanning electron microscopic observation of the parasitic forms of Fonsecaea pedrosoi in a human skin lesion.

Abstract:

:The parasitic form of Fonsecaea pedrosoi in the superficial hyperkeratotic layer of the skin, in a patient with chromoblastomycosis, was observed by a scanning electron microscope using some technical improvements. The fungus elements were comprised of branched septate hyphae with spherical cells and sclerotic cells. It was observed that the sclerotic cells, divided into two or three parts, formed a germ tube.
