Skin Rash: Pictures, Causes, Types, and Treatments
src: www.healthline.com

A rash is a change in human skin that affects color, appearance, or texture.

The rash can be localized in one part of the body, or affecting all the skin. Rashes can cause skin to change color, itch, become warm, wavy, cracked, dry, cracked or blistered, swollen, and may feel pain. The cause, and therefore the treatment for the rash, varies greatly. Diagnosis should consider such things as the appearance of rashes, other symptoms, what patients may experience, work, and events in family members. The rash may last 5 to 20 days, the diagnosis can confirm a number of conditions. The presence of a rash may help diagnosis; related signs and symptoms are diagnostic of certain diseases. For example, the rash on measles is an erythematous, morbilliform, maculopapular rash that begins a few days after the fever begins. The classic starts at the head, and spreads down.

Diagnostic approach

The cause of the rash is very much, which can make rash evaluation very difficult. Accurate evaluation by the provider can only be done in a comprehensive historical context (What medications are the patients using? What is the patient's job? Where the patient is located?) And a complete physical examination.

Matters that need to be considered in the examination include:

  • Appearance: for example. , purpura (typical of vasculitis and meningococcal disease), fine and like emulsions (typical of dengue fever); circular lesions with typical central depression of molluscum contagiosum (and in the past, smallpox); plaque with silver scales typical of psoriasis.
  • Distribution: for example. , a red rash becomes confluent and forms a bright red line in the skin folds of the neck, armpits and groin (Pastia line); chickenpox vesicles seem to follow the body hollows (they are more prominent along the spine depression in the back and in the second hollow of the shoulder blades); very few rashes affecting the palms and soles of the feet (secondary syphilis, rickettsia or spotted fever, guttate psoriasis, hand, foot and mouth disease, keratoderma blennorrhagicum);
  • Symmetry: e.g. , herpes zoster usually affects only one side of the body and does not cross the midline.

The outboard test can be ordered, for diagnostic purposes.

Treatment

Treatment differs according to what is diagnosed by the patient's rash. Common rashes can easily be overcome by using steroid topical creams (such as hydrocortisone) or non-steroidal treatments. Many medications are available at the counter in the United States.

The problem with topical steroid creams is hydrocortisone; is their inability to penetrate the skin through absorption and is therefore ineffective in clearing the affected area, thus making hydrocortisone almost completely ineffective at all except the lightest of cases.
