Atopic and Seborrheic Dermatitis
Which are the symptoms?
Atopic dermatitis is very itchy, as opposed to seborrheic dermatitis. In both dermatitis, erythematous patches are present, with typical localizations. Seborrheic dermatitis has typical localizations.
How is it diagnosed?
The diagnosis of seborrheic dermatitis and atopic dermatitis is primarily clinical. Atopic dermatitis is more itchy and spares the center of the face. Among infants, atopic dermatitis predominantly affects face, forehead, central face area, and large folds, and always resolves by the sixth month. Among adults, atopic dermatitis affects folds of arms and legs, neck and sometimes face. Sometimes pyogenic complications due to staffilococcus aureus are frequent, with formation of pustules and purulent serum exudation.
Seborrheic dermatitis affects young adults, but also children. Among adults, atopic dermatitis affects folds of arms and legs, neck and sometimes face. Sometimes pyogenic complications due to staffilococcus aureus are frequent, with pustules formation and purulent serum exudation.Seborrheic dermatitis affects young adults, but also children. Seborrheic dermatitis is a scarcely itchy disease, influenced by stress and seasonality, with a chronic-recurrent course. It develops in areas rich in sebaceous glands, giving rise to seborrheic dermatitis of the face characterized by erythematous and desquamative lesions with clear-cut margins. The most affected sites of the face are the forehead and the border of the hairline, sometimes the pinnae and the sternal region.
Histopathologic examination is not necessary. Increased IGE levels and IGE-specific antibodies are markers of atopic status with purely biological significance.
How is it treated?
UVB narrow-band phototherapy can be used. Medical treatments include topical steroids, calcineurin inhibitors and emollients. As systemic, steroids, cyclosporine, biologics.
