General Information. Psoriasis is a skin disorder that causes skin cells to multiply up to 10 times faster than normal. This makes the skin build up into bumpy red patches covered with white scales. They can grow anywhere, but most appear on the scalp, elbows, knees, and lower back.  Dr. Liana Abramova and her staff specialize in the diagnosis of psoriasis and will help you understand and manage the condition effectively.  Call Dermatology of Virginia in Fairfax at (703) 828-7128 and schedule your appointment today
