Dermatitis is a group of dermatology conditions that cause skin inflammation. There are many different types of dermatitis, which may be caused by infections, allergies or irritating materials. Your dermatologist can diagnose which type of dermatitis you have so you can begin the proper treatment.

Atopic Dermatitis (Eczema)

This skin condition is characterized by redness, blisters, itchiness, and thick or scaly skin. Symptoms often appear in childhood, and they can continue into adulthood. Atopic dermatitis is hereditary, so if a close family member has it, you or your child is more likely to develop it.

Contact Dermatitis

Subcategories of this condition include irritant contact dermatitis and allergic contact dermatitis. When sensitive skin comes in contact with irritating substances or allergens, it may become swollen, dry, cracked, itchy or blistered. Reactions may occur in response to detergent, soap, metal in inexpensive jewelry or zippers, hair dye, cosmetics, adhesives, and more.

Dyshidrotic Eczema

Also called pompholyx or vesicular eczema, dyshidrotic eczema is characterized by itchy, fluid-filled blisters on the fingers and palms of the hands, as well as the toes and soles of the feet. Outbreaks are often triggered by allergies, stress, wet hands and feet, or coming in contact with irritants in the environment.

Hand Eczema

This type of dermatitis is caused by a combination of genetics and irritating substances. Symptoms include redness, itching, dryness, blistering and cracking of the skin on your hands.


Also known as lichen simplex chronicus, this type of dermatitis typically affects the skin at the nape of the neck, shoulders, scalp, wrists, back of the hands, ankles or feet. The skin may become discolored, thick and scaly when rubbed or scratched.

Nummular Eczema

Skin affected by nummular eczema may develop dry, scaly, coin-sized spots on the skin. Triggers include insect bites, dry skin and inflammatory conditions.

Seborrheic Dermatitis

This type of eczema causes red, itchy rashes to appear on oily parts of the body, including the scalp, nose, eyelids, chest and upper back. Causes include genetics, hormones and microorganisms that live on the skin.

Follicular Eczema

This condition affects hair follicles and is most often found in people with dark skin. Follicular eczema causes small red bumps and itching to develop on the arms, back and upper thighs. Outbreaks can be triggered by stress, poor diet, allergies or changes in the weather.

Dermatitis Herpetiformis

The extremely itchy rash resulting from this condition most often develops on the elbows, knees, buttocks and back. Dermatitis herpetiformis is strongly associated with celiac disease. As a result, people with this condition are often instructed to eliminate gluten from their diet.

Perioral Dermatitis

This common skin problem affects young women and on occasion, men and children. It’s characterized by mild bumps, peeling, itching and burning around the mouth.
