Psoriasis is a chronic skin condition characterized by a higher rate of reproduction. It is not contagious and its morphology is often raised and has silvery scales. Common areas of involvement are the scalp, knees, elbows, hands and feet.
A normal skin cell cycle is about one month, in psoriasis this cycle is shortened to three to four days to mature and move to the surface. Instead of falling off, the cells pile up and form the lesions. Plaque psoriasis is the most common but other variants are guttate, pustular, and inverse psoriasis.
Treatment options include topical therapies, NBUVB phototherapy, oral systemic therapies such as methotrexate and Otezla as well as biologic therapy. All of these treatment options are available at Sand Dermatology.
