Tinea is the term for fungal and yeast infections. Various forms of tinea occur. Tinea versicolor affects the chest and back of sweaty/athletic young adults and can look like faint pink-white patches that leave behind temporary white discoloration, especially on dark-skinned individuals. Tinea capitis is a scalp infection, almost exclusively in children. Fungal infections of the rest of the body tend to occur in damp folds of skin (between toes, under breasts, around the groin); cool, loose cotton clothing, good aeration, and drying powder can help prevent them.
