Tinea or Pityriasis?

Fungi <--> Tinea
But "tinea" generally reserved to describe circinate lesions => 'ring worm'
- in particular, those caused by a dermatophyte

So, tinea => dermatophyte
Generally followed by the region it affects e.g. tinea pedis (foot); tinea corporis (trunk) etc.


Candida albicans and Malassezia furfur
- are yeast-like and not dermatophytes

Candida --> candidiasis
Mallassezia furfur --> pityriasis versicolor (misnomer = tinea versicolor)


Important reason for understanding this

• Tinea, including onychomycosis (nails)
• responds to terbinafine (e.g. Lamisil) and griseofulvin (e.g. Grisovin)
  &
  responds to the "azoles"
• Candidiasis and pityriasis versicolor
• do not respond to terbinafine or griseofulvin
  but
  respond to the "azoles"

So 

• Tinea                                      --> terbinafine or griseofulvin or an azole
• Candidiasis                          --> an azole
• Pityriasis versicolor             --> an azole
