In patients with clinical disease, the organism is found in both the yeast (spore) stage and the filamentous (hyphal) form. Factors that lead to the conversion of the saprophytic yeast to the parasitic, mycelial morphologic form include a genetic predisposition; warm, humid environments; immunosuppression; malnutrition; pregnancy; and Cushing disease. Human peptide cathelicidin LL-37 plays a role in skin defense against this organism.
Additional Skin Conditions (Hyperpigmented macules and patches mimicking tinea versicolor) The patches may be yellow or brownish, or sometimes red or pink.
