Dermatitis is a skin inflammation characterized by red, dry and itchy skin. If the condition gets severe, it could also lead to painful cracks, crusty scales, and fluid filled blisters. There are many types of dermatitis and the diagnosis is done based on the category of dermatitis affecting the skin. The symptoms, as well as the treatment of these different types of dermatitis, are fairly similar.
Eczema is a condition in which the affected person experiences a dry, red and itchy area on the skin caused due to inflammation. Although it is most common in children, people of any age can get affected too. Eczema also goes by the name atopic dermatitis and the treatment can include anything from oral medications to steroid creams to light therapy depending on the severity of the condition.
Erythema is a skin inflammation on the fatty layer of the skin. On spreading of the legs, they give the skin a red appearance along with pain and tender lumps. The lumps could vary in size from one to five centimeters. They usually affect the front part of the legs. Erythema is a self-limited skin condition and even if no treatment is taken, it can clear off by itself within a period of 3 to 6 weeks. After healing, it may leave behind a bruised appearance over the area where the fatty layers had been destroyed. This, however, fades with time.
Folliculitis is a condition in which the hair follicles get inflamed. This could develop in any part of the body that has hair, but is most common in the beard area, arms, buttocks, backs, and legs.
