What skin condition is often linked to arthritis?

Psoriasis is frequently associated with arthritis, particularly a form known as psoriatic arthritis. This condition typically presents with both skin lesions and joint inflammation, making it a unique manifestation that connects dermatological and rheumatological symptoms. The skin lesions of psoriasis are characterized by red, raised patches covered with silvery-white scales. These lesions often find their starting point on the elbows, knees, or scalp, but can occur anywhere on the body.

The connection between psoriasis and arthritis stems from underlying immune system dysfunction, which causes inflammation in both the skin and the joints. Individuals with psoriasis are at a heightened risk of developing psoriatic arthritis, with estimates suggesting that around 30% of individuals with psoriasis will experience arthritis-like symptoms at some point in their lives. Recognizing this relationship is critical for timely diagnosis and treatment, allowing for better management of both the skin and joint manifestations of the disease.
