Introduction

What is chest rash?

Rash is a symptom that causes the affected area of skin to turn red and blotchy, and to swell. A rash may cause spots that are bumpy, scaly, flaky, or filled with pus. Rashes can vary in location, pattern and extent and may occur in any area of the body. A chest rash can have a variety of causes, and it may indicate something occurring around the chest itself or suggest a systemic (body-wide) condition.

Contact dermatitis (skin inflammation) is caused by an adverse reaction to something that touches the skin, including chemicals found in detergent, soap or a fragrance. For example, you may develop a rash on your chest when you wear a shirt that was washed with a particular detergent or treated with a chemical. Metal, such as a necklace rubbing against your chest, can also cause chest rash. Other forms of contact dermatitis include exposure to certain plants, such as poison oak or ivy, an animal bite, or an insect sting. Lyme disease is caused by tick bite, which can first appear as a circle with a bull’s-eye pattern, then progress to a rash.

Allergies to food and medications are potentially serious sources of rash. Peanuts, shellfish, strawberries and avocados are just some of the foods that can trigger allergic reactions. These foods may cause mild reactions; however; in some cases, reactions could develop into potentially life-threatening conditions characterized by vomiting, difficulty breathing, or swelling. Allergic purpura is a serious, often life-threatening allergic reaction that can cause a chest rash but can also affect the joints, gastrointestinal tract, and kidneys.

Rashes may also be associated with in skin conditions, such as eczema, psoriasis and impetigo. Some of these are chronic skin conditions that may flare up for a time, then resolve. Other causes of rash include autoimmune disorders that occur when the body is attacked by its own immune system, which normally serves to protect it from foreign invaders (antigens). Many viruses that occur during flu season, or those associated with childhood diseases, can produce rash.

Rashes can be caused by an allergic reaction to food, medications, lotions or detergents. These reactions can range from mild to potentially life threatening, especially if swelling and constriction of breathing occurs, which could indicate anaphylaxis. Seek immediate medical care (call 911) if a rash is accompanied by any of the following symptoms, including swelling of the face, swelling and constriction of the throat, difficulty breathing, fainting, change in level of consciousness or alertness, pale skin, or purple rash.

Seek prompt medical care if a rash is persistent and causes you concern.

Causes

What causes chest rash?

  • Cosmetics, dyes or detergents
  • Industrial chemicals, such as those found in elastic, latex and rubber
  • Metallic substances such as jewelry
  • Poison ivy or oak

Other allergic causes of chest rash include:

  • Eczema (skin disorder causing scaly or blistering rashes that may be caused by allergy)
  • Insect bite allergy such as a bee sting

Infectious causes of chest rash

Chest rash can also be caused by infections including:

  • Eczema (skin disorder causing scaly or blistering rashes that may be caused by infection)
  • Impetigo
  • Meningitis (infection or inflammation of the sac around the brain and spinal cord)
  • Pityriasis rosea (rash resembling the shape of a pine tree)
  • Pyoderma gangrenosum (gangrene)
  • Rocky Mountain spotted fever

Autoimmune causes of chest rash

Chest rash can also be caused by autoimmune disorders including:

  • Kawasaki disease (rare, serious pediatric disorder characterized by inflammation of blood vessels, high fever, rash, and mucous membrane changes)
  • Psoriasis
  • Systemic lupus erythematosus (disorder in which the body attacks its own healthy cells and tissues)

Questions for diagnosing the cause of chest rash

To diagnose your condition, your doctor or licensed health care practitioner will ask you several questions related to your rash including:

  • When did the rash begin?
  • Are you breastfeeding?
  • Are you taking any medications?
  • Do you have allergies?
  • Does the rash cause any itching or scaling
  • Do you feel otherwise healthy?
  • Have you tried any new products recently, such as soaps, perfumes or sprays?
  • Have you spent a lot of time outdoors lately?

What are the potential complications of chest rash?

Because chest rash may be due to serious diseases, failure to seek treatment can result in serious complications and permanent damage. For example, infectious diseases, such as mumps or measles, can lead to rare but serious complications, including miscarriage, hearing loss, and serious brain infections, such as encephalitis or meningitis.

Once the underlying cause of your rash is diagnosed, it is important for you to follow the treatment plan that you and your health care professional design specifically for you to reduce the risk of potential complications including:

  • Cognitive difficulties
  • Meningitis (infection or inflammation of the sac around the brain and spinal cord)
  • Paralysis
  • Permanent hearing loss
  • Secondary infections, which may develop from scratching and related skin trauma
