Doctor's Notes on Rash Causes, Symptoms, Signs, Treatment, and Cure

A rash is a general, nonspecific term that describes any visible skin outbreak. Rashes have many different signs and symptoms; the signs and symptoms may be described as flat (macular), raised or bumpy (papular), raised and sheet-like (plaque), a mixture of flat and raised (maculopapular), small bumps with pus (pustular), acneiform (small or large pimples), small clear blisters (vesicular), scarlet, red or pink color, petechial (tiny pinpoint red), silvery white scales (psoriasis), annular or bullseye (circular with central clearing), eczematous (dry, scaly, rough, thick and possibly discolored) and/or excoriated (areas of scratched skin that may appear with any skin rash that is itchy).

Causes of rashes are usually categorized into two groups; infectious and non-infectious. Causes of infectious rashes are due to large number of infectious agents; for example, fungal, bacterial, viral and parasitic organisms. Non-infectious causes of rashes include drug allergies, contact dermatitis, eczema, allergic dermatitis, irritant dermatitis from chemicals, food allergies and some medical disorders.
