Rash: Introduction

A rash is an abnormal condition and reaction of the skin. A rash can be a symptom of a wide variety of mild to serious diseases, disorders and conditions. A rash can result from infection, irritation, inflammation, allergy, insect bites and other abnormal conditions.

A rash can occur in any age group or population. A rash can indicate a mild condition, such as a fungal infection called ringworm or contact dermatitis. A rash can also be the result of a moderate condition, disorder or disease, such as an allergy, chicken pox, hives or a parasitic infection of the skin called scabies. A rash can also occur in some serious, even life-threatening conditions, such as in meningitis or severe allergic reactions that include anaphylaxis and allergic purpura.

Depending on the cause, a rash can be short-term and disappear quickly, such as when a rash occurs due to shaving or a waxing treatment to remove body hair. A rash can also occur in sudden episodes, such as a rash that happens when a person is exposed to an allergen that causes a rash or to certain plants, such as poison ivy. A rash can also occur over a relatively long period of time, such as when a rash is due to chicken pox or chronic eczema.

A rash can be the result of a wide variety of other conditions. These include methamphetamine abuse, stress, anxiety, and skin conditions, such as pityriasis rosea, acne, dermatitis, eczema and psoriasis. A rash can also be due to parasitic infections, such as public lice, head lice, and fungal infections, such as jock itch and athlete's foot. A rash can be due to infectious diseases, such as rubella, meningitis, Lyme disease and measles.

The appearance and symptoms of rashes vary greatly depending on the underlying cause. A rash can occur by itself or in conjunction with other symptoms, which vary depending on the underlying disease, disorder or condition. Other symptoms can include fever, runny nose, red eyes, cough and sneezing. Complications of a rash can occur from excessive scratching. The underlying disorder, disease or condition can also cause complications. For more details about symptoms and complications, see symptoms of a rash.

Diagnosing a rash and its root cause begin with taking a thorough personal and family medical history, including symptoms and exposure to common allergens and infectious diseases, and completing a physical examination.

If an allergy is suspected to be the cause of a rash, diagnostic testing may include skin patch testing. In a skin patch test, small amounts of common allergens are applied methodically to the skin to determine what substances are triggering an allergic response. A blood test called a radioallergosorbent test (RAST) may also be done to help identify the substances that are causing an allergy. For suspected food allergies, a patient may also be asked to keep a log to record the types of foods that trigger an allergic reaction that includes a rash.

Making a diagnosis also includes performing a variety of other tests to help to determine other potential underlying diseases, conditions or disorders, such as meningitis and other infectious diseases. Diagnosis may also include a complete blood count, a blood test which can help to determine if an infectious process is present. A lumbar puncture may be done if meningitis is suspected.

A diagnosis of a rash and its underlying cause can easily be delayed or missed because a rash may be mild or intermittent and for other reasons. For information on misdiagnosis, refer to misdiagnosis of a rash.

Treatment of a rash involves diagnosing and treating the underlying disease, disorder or condition that is causing it. Some conditions can be easily and successfully treated and cured, while others may require more intensive treatment. For more information on treatment, refer to treatment of a rash....more »

Diagnostic tests for Rash:

Various tests are used in the diagnosis of Rash. Some of these are listed below :

  • Skin examination
  • Physical examination
    • Note characteristics of skin rash - e.g. macular, papular, pustular, vesicular, bullous, scaly, ulcers - will help determine the cause of the rash (e.g. a macular or papular rash may suggest eczema, contact dermatitis, exfoliative dermatitis, pityriasis rosea or a drug reaction; a pustular rash may suggest staphylococcus, scabies or a fungal skin infection; a vesicular or bullous rash may suggest chicken pox, dermatitis herpetiformis, contact dermatitis, pemphigus, bullous impetigo or nummular eczema; a scaly rash may suggest ichthyosis, psoriasis, lichen planus, fungal skin infection, exfoliative dermatitis or a drug eruption; an ulcerative rash may suggest a basal cell carcinoma).
    • Note distribution of the skin affected - e.g. focal or diffuse (e.g. focal rash may suggest fungal skin infection, scabies, contact dermatitis, skin tumor, nummular eczema or impetigo; diffuse rash may suggest psoriasis, lichen planus, eczema, drug eruptions, dermatitis herpetiformis, pemphigus, pityriasis rosea or tinea versicolor.
    • What areas of the body does it primarily involve - e.g. extremities, face, trunk? - will help determine the cause (e.g. extremities may suggest atopic dermatitis, tinea, psoriasis or insect bites; typical lower leg rashes include keratitis pilaris, erythema nodosum, nummular dermatitis, stress dermatitis, necrobiosis lipoidica; typical rashes on the front of the knees include psoriasis and dermatitis herpetiformis).
