1.3-CLINICAL CLASSIFICATION Flashcards
CLINICAL CLASSIFICATION OF FUNGI
✓ Superficial mycoses
✓ Subcutaneous mycoses
✓ Systemic mycoses
✓ Opportunistic mycoses
Fungal infections that involve the hair, skin, or nails
SUPERFICIAL OR CUTANEOUS MYCOSES
SUPERFICIAL OR CUTANEOUS MYCOSES
Fungi in this category include the
dermatophytes
dermatophytes infect
keratinized tissues
Confined to the subcutaneous tissue
SUBCUTANEOUS MYCOSES
Examples of subcutaneous infections include
chromoblastomycosis, mycetoma, and
phaeohyphomycotic cysts (Wangiella or Exophiala dermatitidis)
Primarily involve the lungs but also may become widely
disseminated and involve any organ system
SYSTEMIC MYCOSES
Systemic fungal infections include the genera
Blastomyces, Coccidioides, Histoplasma, and
Paracoccidioides
may also be considered a part of SYSTEMIC MYCOSES
P. marneffei
MOT SYSTEMIC MYCOSES
INHALATION
The infections these organisms cause occur primarily in
patients with some type of compromise of the immune
system.
OPPORTUNISTIC MYCOSES
Most commonly encountered genera in this opportunistic group are
Aspergillus, Candida, and Cryptococcus
Also Zygomycetes
Superficial Mycosis
Pityriasis versicolor
Tinea nigra
