What Is Pruritic Skin?

Pruritic skin is a symptom of a primary disease that may involve only the skin or a systemic disorder with other features and is characterized by chronic itching.

Q: What part of skin is affected by itchiness?

A: Itching may arise from any layer of skin, depending on the cause.

In the image to the right, the outermost protective surface layer, or stratum cornem, is shown as a thin tan line. It is the top dead layer of the epidermis that normally sloughs off as new cells move up to replace it. The epidermis is shown as a dark pink layer. It is composed of five layers of keratinocytes that flatten as they move upward.

The pink layer under the epidermis is the dermis, or true skin, which is composed of collagen and elastin tissue. It contains oil glands that lubricate skin, sweat glands, blood vessels, nerve endings, lymphatics, and hair follicles. Under the dermis is subcutaneous tissue containing fat cells here colored yellow on the bottom of the image.
