Seborrheic dermatitis is a papulosquamous disorder patterned on the sebum-rich areas of the scalp, face, and trunk.
In addition to sebum, this dermatitis is linked to Malassezia,
immunologic abnormalities, and activation of complement.
Its severity ranges from mild dandruff to exfoliative erythroderma.
Pharmacologic agents that may be used include the following:
Topical corticosteroids (discouraged except for short-term use and at risk for tachyphylaxis when used as monotherapy)
For skin involvement, ketoconazole, naftifine, or ciclopirox creams and gels alternatively, calcineurin inhibitors.
For acute flares, class IV or lower corticosteroid creams, lotions, or solutions.
For severe or unresponsive lesions, systemic fluconazole.
