What kind of doctor is needed to diagnose plaque psoriasis?

A board-certified dermatologist or rheumatologist is the best doctor to see to diagnose and treat your plaque psoriasis, but many other doctors can recognize it. Primary care physicians, like family or internal medicine doctors, can certainly recognize plaque psoriasis, and are knowledgeable and experienced enough to recommend effective self-treatment for mild cases. In more moderate or severe cases, these doctors may opt to refer you to a dermatologist, or rheumatologist though, since it’s their specialty after all.
