Localized scratch dermatitis
A chronic, itchy inflammation of the skin that usually affects more women than men, and more Asians and American Indians than other races.
It is a result of chronic scratching of a skin area, which causes itching. This triggers more scratching, leading to a vicious circle called the itch-scratch cycle. The exact cause is unknown. Psychologic factors could play a role.
The condition can happen anywhere on the skin, including the anus. Symptoms may include:
Dryness and scaling
Dark areas from rubbing
Effective treatment usually includes stopping of scratching or rubbing. Other treatment may include:
Antihistamines or topical medicines to control itching
Over-the-counter moisturizing creams
A chronic rash that most commonly affects middle-aged people and is more common in the winter. It can last for months.
The cause is unknown. But it may be related to having dry skin or taking certain medicines.
With this condition there are round spots with small blisters, scabs, or scales. This condition can happen anywhere on the body. But it usually appears on the back of the arms and legs, and on the buttocks. Other symptoms may include:
Itchy areas of pimples
Always see your healthcare provider for a diagnosis.
Treatment depends on the individual person, as 1 treatment approach is not effective for everyone with this condition. Treatment may include:
Ultraviolet light therapy
Protecting skin from injury
A red, bumpy rash around the mouth and chin that usually affects women between the ages of 20 and 60.
The cause is unknown. But it may be related to the use of topical steroids in certain cases.

Treatment may include:
Isotretinoin (acne medicine)
Topical metronidazole or clindamycin or sodium sulfacetamide
A chronic inflammation of the lower legs caused by poor circulation. This leads to pooling of blood and fluid under the skin. The condition tends to affect people with varicose veins and swelling (edema). It is most often seen in the ankles and can spread up to the knees.

Red and scaly skin that is irritated
The goal of treatment is to reduce the pooling of blood in the veins in the legs. Treatment may include:
Raising (elevating) the legs
Wearing prescription compression stockings to prevent fluid buildup
Applying cool compresses
Keeping the skin clean to prevent infection
Antibiotics (if infection occurs)
Zinc oxide dressings
Skin grafts (if the skin develops large ulcers)
