Psoriasis is what kind of disease
Many people who have psoriasis also have serious health conditions such as diabetes, heart disease, and depression. Psoriatic arthritis has many of the same symptoms as other types of arthritis, so a rheumatologist (arthritis doctor) is often the best doctor to diagnose it.atches are typically found on the elbows, knees, scalp, lower back, face, palms, and soles of feet, but can affect other places (fingernails, toenails, and mouth). The most common type of psoriasis is called plaque psoriasis.
