WebMD states that seborrheic dermatitis presents as a red rash with yellow scaling on the scalp, eyebrows, around the nose and behind the ears. The rash may have oily, waxy scales. In children, it is called cradle cap. Stasis dermatitis can cause scaling and swelling in the lower extremities. The rash can present as ulcerated sores or open skin around the ankles or inner legs. Atopic dermatitis (eczema) presents as incredibly itchy patches of red, dry skin. Mayo Clinic states that atopic dermatitis tends to occur behind the knees, elbows and front of the neck. If the rash is overly scratched, it weeps and crusts over.
WebMD explains that most forms of dermatitis respond well to over-the-counter treatments, but if the rash does not disappear, then a doctor should be consulted. Dermatitis that begins oozing yellow liquid is a sign of an infection and should be treated with antibiotics.Learn more about Skin Conditions
