Skin conditions associated with arthritis
What other dermatologic conditions have been associated with arthritis? What musculoskeletal manifestations are typically associated with these?
Palmoplantar pustulosis, acne conglobata, acne fulminans, psoriatic onychopachydermoperiostitis, and hidradenitis suppurativa. Note that acne vulgaris is not included. These typically are associated with anterior chest wall pain and swelling, involving the sternoclavicular, manubriosternal, and sternocostal joints. Chronic cervical and lumbar pain as well as pain at the symphysis pubis is common. Less often, oligoarticular or monoarticular peripheral arthritis can occur. Wrists, PIPs, elbows, acromioclavicular joints, and metatarsophalangeal joints are the most commonly involved.
