Dermatology Vancouver - A skin rash is defined as a change of the skin which affects its color, appearance or texture.

Normally, rashes could cause the skin to change color. The causes and treatments for rashes vary considerably depending on the diagnosis. The diagnosis is formed by considering a variety of factors such as the rashes' overall appearance, what the individual's occupation is, what the person may have been exposed to, other indications and the family history. The diagnosis can in fact confirm any number of health issues.
The rash may help to indicate certain associated symptoms and signs that are common to particular diseases.

The appearance of the rash, like for example, is it fine and sandpaper as found with scarlet fever, is it purpuric, that is normal for vasculitis and meningococcal disease? Does the rash consist of circular lesions with a central depression, which is typical of molluscum contagiosum and small pox? Or is the rash consisting of plaques with silver scales that is commonly seen with psoriasis?
What is the distribution of the rash? Like for instance with chicken pox, the vesicles normally follow the hollows of the body; hence, they are most prominent in the hollows of both shoulder blades as well as along the depression of the spine on the back. The rash presented with scarlet fever becomes confluent and forms bright red lines in the skin creases of the armpits, groins and neck. These lines are called Pastia's lines.

Normally, it is good advice not to scratch the rash. This is due to the scratching causing a spread of the rash. It could be tempting to softly rub the affected area in order to provide temporary relief but it is better to avoid contact with the affected parts completely.
