Study Notes
Chromoblastomycosis Features
- Distinguishing feature upon histologic examination is the presence of sclerotic bodies.
- Sclerotic bodies are typically brown in color.
Conidiation and Species
- Potato Dextrose Agar is used to enhance conidiation in Fonsecaea spp.
- Primary mode of conidiation in Rhinocladiella type is through conidiophores producing conidia.
Etiologic Agents
- The Trichophyton species complex is NOT listed as an etiologic agent of Chromoblastomycosis.
Subcutaneous Mycoses
- Main cause of subcutaneous mycoses involving the skin is the inoculation of certain fungi.
- Subcutaneous mycoses are usually acquired through traumatic implantation of the pathogens.
Affected Body Parts
- Commonly affects the extremities, particularly hands and feet.
Phaeohypomycosis Characteristics
- Phaeohypomycosis is characterized by darkly pigmented fungi.
- Phaeohypomycotic cysts are noted for their unique appearance, often showing a brown-black pigmentation.
Common Features of Subcutaneous Mycoses
- Both Actinomycotic (bacterial) and Eumycotic (fungal) subcutaneous mycoses share similarities, including local tissue involvement and difficult-to-treat infections.
