Localized scratch dermatitis

Also called neurodermatitis. A chronic, itchy inflammation of the skin that is more
common between ages 30 and 50, and usually affects more women than men.
It's a result of chronic scratching of a skin area, which causes itching. This sets
off more scratching, leading to a vicious circle called the itch-scratch cycle. The
exact cause is unknown. Psychological factors could play a role.

The condition can happen anywhere on the skin, including the anus. Symptoms may include:

Effective treatment usually includes stopping of scratching or rubbing. Other treatment
may include:

Nummular dermatitis

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

Dry skin
Always see your healthcare provider for a diagnosis.
