How can I tell if my rash is psoriasis?

Psoriasis is not to be confused with the dry, scaly skin that many people develop in the wintertime. Psoriasis can be located anywhere on the body, although it is commonly located on the elbows, knees, scalp, and belly button and may also affect the nails. These characteristic locations, as well as the red scaly plaques, are highly suggestive of psoriasis. The psoriasis rash of red and scaling skin can be dime sized in area to several inches in diameter. A family history of psoriasis points to the possibility of psoriasis. Because of its characteristic patterns, psoriasis can usually be diagnosed by a physician without a biopsy.

Dr. Lowell Goldsmith and Dr. Jeff Bernhard contributed their expertise on behalf of VisualDx for the above information.
