Fungal Infections of The Skin

A mycotic infection of man or animals caused by a number of hyaline (non-dematiaceous) hyphomycetes where the tissue morphology of the causative organism.

These are fast growing, terrestrial, largely saprobic fungi with non-motile cells; cosmopolitan (~867 species). Hyphae coenocytic and mostly.

Primary cutaneous and subcutaneous infections usually the result of a "barrier break" or traumatic implantation of fungal elements. Lesions vary considerably.

Presentation transcript:

A mycotic infection of humans and lower animals caused by a number of dematiaceous (brown-pigmented) fungi where the tissue morphology of the causative organism is mycelial. This separates it from other clinical types of disease involving brown-pigmented fungi where the tissue morphology of the organism is a grain (mycotic mycetoma) or sclerotic body (chromoblastomycosis). Clinical forms of the disease range from localized superficial infections of the stratum corneum (tinea nigra) to subcutaneous cysts (phaeomycotic cyst) to invasion of the brain. Distribution: World-wide. Aetiological Agents: Various dematiaceous hyphomycetes especially Cladophialophora bantiana, Curvularia sp., Bipolaris sp. and Exophiala jeanselmei. Phaeohyphomycosis
