Basics
Description
Chronic, superficial, recurrent inflammatory skin disorder affecting sebum-rich, hairy regions of the body, especially the scalp, eyebrows, and face and to lesser extent, chest, and back
Epidemiology
Incidence
Prevalence
Etiology and Pathophysiology
- Skin surface yeast such as Malassezia may be a contributing factor (3).
- Genetic and environmental factors: Flares are common with stress/illness.
- Parallels increased sebaceous gland activity in infancy and adolescence or as a result of some acnegenic drugs.
- Seborrheic dermatitis is more common in immunosuppressed patients, suggesting that immune mechanisms are implicated in the pathogenesis of the disease, although the mechanisms are not well defined (3).
Genetics
Positive family history; no genetic markers have been identified to date.
Risk Factors
- Immunosuppressed conditions such as AIDS, lymphoma, organ transplantation (2),(4)
- Parkinson disease, epilepsy, traumatic brain, and spinal cord injury (4)
- Emotional stress (2)
- Obesity (2)
- Oily skin (2)
- Acne (2)
- Medications may cause flares/induce seborrheic dermatitis: buspirone, chlorpromazine, cimetidine, ethionamide, griseofulvin, haloperidol, interferon-α, methyldopa, psoralen, IL-2 (2)
General Prevention
