Overview & Considerations
When diagnosing rashes, your physician must first determine what types of lesions appear within the eruption. Rashes may be formed from macules, patches, papules, plaques, nodules, pustules, bullae, or vesicles. Based upon the type of lesion within your rash, the history of your rash, and the location of your rash, your doctor will be able to arrive at possible causes.
In many cases, vesicles break easily and release their fluid onto the skin. When this fluid dries, yellow crusts may remain on the skin surface. Be sure to let your physician know if vesicles were present before you arrived at the office.
