Seborrheic Dermatitis in Adults
Seborrheic Dermatitis presents as moist, transparent to yellow, greasy scaling papules among red patches and plaques. Seborrheic Dermatitis usually favors areas where the concentration of sebaceous glands is maximal such as the scalp margins, central face and presternal areas, Characteristic locations are the eyebrows, the base of eyelashes, nasolabial folds and paranasal skin, and external ear canals. Scale adherent to the eyelashes and lid margins with variable amounts of erythema is characteristic of seborrheic blepharitis. Flexural skin may be similarly involved including the postauricular, inguinal, and inframammary folds as well as the anogenital area.
Adults tends to have a chronic course with remissions and exacerbations. Flares are precipitated by stress, fatigue, and seasonal climate change.
