Seborrheic Dermatitis
Key Points
In adults, seborrheic dermatitis causes dandruff and sometimes scaling on the scalp, around the eyebrows, nasolabial folds, nose, external auditory canal, behind the ears, and on the sternum. Seborrheic dermatitis can cause a thick, yellow, crusted scalp lesion in newborns or thick, scaly scalp plaques in older children and adults. Treatments include topical antifungals; antifungal, keratolytic, and tar shampoos; and topical corticosteroids.
