M07.0: Distal interphalangeal psoriatic arthropathy

Distal interphalangeal psoriatic arthropathy (M07.0) is a medical condition characterized by the combination of psoriasis and arthritis, affecting the distal interphalangeal joints, which are the small joints at the tips of the fingers or toes. Psoriasis is an autoimmune skin disease that speeds up the life cycle of skin cells, causing them to build up quickly on the surface of the skin. The resultant inflammatory process may extend to the joints, especially those of the fingers and toes, in what is known as psoriatic arthritis. Patients with this condition might experience symptoms like joint pain and swelling, stiffness, and difficulties in movement, along with psoriasis symptoms like red patches of skin covered with thick silvery scales. The exact cause is unknown, though it is thought to involve genetic, immune system, and environmental factors. The disease progression can vary greatly from patient to patient, and there may be cycles of flare-ups and remission. It can affect anyone of any age but is most commonly diagnosed between the ages of 30 and 50.
