Plaque Psoriasis Diagnosis and Treatment

See Psoriasis, When to Seek Medical Care for information about when to see your doctor about plaque psoriasis. Psoriasis is typically diagnosed after the doctor or health care practitioner does a physical exam. The doctor generally can tell if it is psoriasis just by observing the patches on the skin. The typical appearance of psoriasis is noted in Psoriasis, Symptoms.
 
Skin biopsies can confirm the diagnosis of plaque psoriasis. However, they are usually used to evaluate unusual cases or to rule out other conditions when the diagnosis isn't certain.
