Psoriatic arthritis (PsA) is a seronegative spondyloarthropathy characterized by peripheral arthritis, enthesis, spondylitis, and psoriasis. Lymphedema arises from the slowing of lymphatic flow because of inflammatory or noninflammatory diseases such as tumors, infections, bursitis, rheumatoid arthritis, and polymyalgia rheumatica. It is commonly encountered in one or more regions of distal extremities. Lymphedema is a rare complication of PsA, and it is commonly seen asymmetrically and in lower extremities. We aimed to report a case, who followed-up with diagnosis with PsA and with complaints of upper extremity swelling and bilateral upper extremity lymphedema diagnosed as a result of the review.
