Fungal Human Pathogens: Mycosis Categories

The idea
Cutaneous and systemic mycoses classify by depth of invasion; opportunistic instead names infections striking a weakened host.
In practice
Athlete's foot is cutaneous; histoplasmosis, entering the lungs, is systemic; candidiasis is opportunistic and can itself turn systemic.
Where people slip
Opportunistic classifies by host condition, not depth, and cuts across cutaneous and systemic — an opportunistic mycosis can itself be systemic.
