Yeast thrives in warm moist areas created by skin folds. Pendulous breasts in older women predispose. Red plaques appear, increasing in size. Satellite pustules appear beyond plaque edge.

Candida infections of the axillae occur in the obese, especially in warm humid weather. The red plaques with satellite pustules occur just as they do under the breasts and on groin.

Maceration causes pustules to rupture and skin to scale. Painful fissures may develop at the base of the skin fold.
