Because of a lack of specific biologic tests, precisely defining psoriatic arthritis remains difficult. The disorder most commonly exists as a seronegative oligoarthritis found in patients with psoriasis. Distal joint involvement and arthritis mutilans are less common but characteristic differentiating features. Although psoriatic arthritis was originally thought to be relatively mild, as many as 40% of patients may develop erosive and deforming arthritis. How much do you know about this condition? Test your knowledge with this short quiz.
