Dermatitis is a skin condition that results in an irritation of the skin. Blisters and itchy red rashes are some of the common issues that occur with Dermatitis.
There are three main types of Dermatitis; atopic dermatitis, contact dermatitis, and seborrheic dermatitis. These three types can also be classified as eczema.
Atopic dermatitis involves a reoccurrence of an inflamed rash that is usually caused by an overreaction of the immune system. This dermatitis is usually hereditary and can usually be found on the skin of the neck, knees, and elbows. The rashes that are attributed to atopic dermatitis tend to be inconsistent and usually fade and then can reappear again. Atopic dermatitis rashes are characterized by dry, scaly patches of skin that are red and quite itchy.
The second most common type of dermatitis is contact dermatitis. Contact dermatitis occurs as a result of the skin coming in contact with an irritating substance, or object. More commonly this can be considered an allergic reaction. It can occur anywhere on the skin and appears as a rash that is red and covered in several small bumps. There is also a chance that swelling and blisters may occur, depending on the severity of the substance that the skin had come in contact with.
The third most common form of dermatitis is Seborrheic Dermatitis. In children, it is commonly known as cradle cap, but it can also clear up within a few months. A majority of the time it is an issue that occurs on, or around, the scalp, but can appear in other areas such as the nose and the upper back. Areas that have been affected by seborrheic dermatitis tend to be red, oily and itchy. Since this condition normally involves fungal microorganisms, certain antifungal medications can help to alleviate symptoms.
It is important to remember that all types of dermatitis occur on the skin.
