The change of the skin that affects its appearance, color, or texture is called a skin rash.

On the basis of extremely broad spectrum of the causes which bring the skin rashes on, the evaluation of a rash becomes too difficult. It requires a complete and brief history of the patient. However, some of the important symptoms which are commonly found involve:
