As the cause of rashes varies, it is important to have any rash appearing on your body examined by our dermatologist at Piedmont Plastic Surgery & Dermatology. A professional evaluation will serve to ensure the rash isn’t caused by a more serious skin or body health issue.

What is a Rash?

A rash is an irritation of the skin characterized by a change in skin texture that includes redness, itching, irritation, and inflammation. While some rashes will develop suddenly, others develop slowly over the course of several days.

What causes Rashes to Form?

There are many types of rashes, and each type has its own unique cause.

  • Contact dermatitis is the result of coming into contact with a skin irritant producing an itchy or painful rash.
  • Eczema is a blanket term used to describe a range of skin issues that produce patches of skin which is dry, scaly, red, and itchy.
  • Granuloma annularae is a degenerative skin condition in which small red bumps form ring-like patterns over the surface of the skin. It is most often found on the hands and feet.
  • Pityriasis rosea begins with what is known as a “herald patch,” a patch on the skin which can vary in size from less than one inch to four inches in diameter that is scaly and raised. This patch is followed by a series of smaller bumps which can appear to be, scaly, raised, and itchy.
  • Lichen planus is a condition that can appear on the skin, nails, hair, and mucous membranes producing flat, itchy bumps with a purplish hue.

How are Rashes Treated?

Most rashes clear up relatively quickly on their own. Others, however, need treatment from a skilled dermatologist. Typical treatment methods include moisturizers, lotions, corticosteroid creams, antihistamines, or soothing baths to help alleviate symptoms.
