Dematiaceous fungi - phaeohyphomycosis and chromomycosis unknown 13

Описание: Ants and earthworms aren’t the only things in the soil.

Phaeohyphomycosis is a term used to describe a large and diverse group of pigmented molds /fungal infections in the skin. These organisms have hyphae and yeast forms. Chromomycosis lack hyphae forms. Culture is necessary for speciation.

In general, the localized forms are found in individuals with an intact immune system while systemic infections are in immunocompromised. The appearance of the lesions can range from nodules to cystic and occasionally wart or squamous cell carcinoma-like.

The organisms are found in wood, soil, and vegetation and are typically introduced into the skin by a splinter or other traumatic inoculation.

Characteristic microscopic findings:

1. Cavity or cyst surrounded by mixed inflammation with giant cells, histiocytes, and neutrophils.
2. Brown filamentous, thick-walled hyphae and yeasts with bubbly cytoplasm.
3. Differs from chromomycosis which are round spherical organisms that undergo internal septation
