Abstract
Seborrheic dermatitis is a common chronic-recurrent inflammatory
disorder that most commonly affects adults; however, a more transient
infantile form also occurs. The definitive cause of seborrheic dermatitis
is unknown. However, proliferation of Malassezia species has been
described as a contributing factor. The disorder commonly affects the
scalp, face, and periauricular region, with the central chest, axillae, and
genital region also involved in some cases. Pruritus is not always
present and is relatively common, especially with scalp disease. A
variety of treatments are available including topical corticosteroids,
topical antifungal agents, topical calcineurin inhibitors, and more
recently, a nonsteroidal device cream.
Cont
The reported prevalence of SD in the overall adult population
ranges from 1 to 5 percent, and the disorder can affect any
