Any type of rash or inflammation of the skin is often referred to as dermatitis. Many types of dermatitis are also known as eczema.
There are three main types of dermatitis rashes. They are seborrheic dermatitis, acne rosacea, and intertrigo.
Seborrheic dermatitis can be recognized by the small reddish yellow scaling and slightly raised patches in the skin area that is usually oily. This can be noticed in the scalp, around the ears, the eyebrows and eyelids, somewhere on the face, and the chest. When it forms on the scalp, it is the most common cause for dandruff. Seborrheic dermatitis can be caused by stress.. People with Parkinsonism can get it after certain types of drug therapy.
Acne rosacea usually begins sometime during middle age. This type of skin problem is recognized because it often appears over the nose and cheeks. It is red and slightly raised. As this condition progresses, the reddened areas become thick and spots of infection develop. Eventually this type of rash can expand over the entire nose, the cheeks and the lids. It is sometimes caused by overuse of corticosteroid creams used for the treatment of other skin problems. Treatment for this type of skin problem is the use of an antibiotic drug known as tetracycline. This drug may suppress rosacea but it is not a cure.
Intertrigo is a rash or an inflammation that occurs in the folds of the skin such as the fold that forms when you fold your arms (armpits) or the fold that forms in the back of the knees when you bend your knees Intertrigo can also occur under the breasts and between the toes and fingers. This type of rash can occur anytime there is moisture or heat in these areas. Intertrigo is common in obese people.
The best treatment for intertrigo is to lose weight, keep affected areas as clean and as dry as possible, and apply a corticosteroid or antifungal cream.
It is important to consult your doctor in the following instances:
If there is a new skin rash that is spreading; especially if it is near the eyes
If fever or chills develop
If medication is not effective in controlling the skin rash
If there are flare-ups, don’t wait to call the doctor. Call immediately.
