Psoriatic arthritis: A permanent new challenge for dermatologists (Review).

Considering that most of the patients (>2/3) are diagnosed with psoriasis in the cutaneous form long before the joint damage occurs and, in these conditions, a significant proportion of them is found in the dermatologist's initial records, a question must be asked: when is it necessary to send these patients to a rheumatology consultation? The recognition of psoriatic arthritis in patients with vulgar psoriasis and the dermatologist's ability to differentiate it from other arthritis, offers the opportunity to improve patient prognosis by prompt intervention and close collaboration with the rheumatologist. Diagnosis of early psoriatic arthropathy should be considered when a patient with psoriasis or family history of psoriasis has peripheral inflammatory arthritis (oligoarthritis or distal interphalangeal joints damage), enthesitis, dactylitis, spinal pain of inflammatory type. Given that patients with psoriasis are included in the dermatologists' medical records, it is very important to recognize psoriatic arthritis in patients with cutaneous psoriasis, to differentiate it from other possible arthritis, thus having the possibility to improve patient prognosis by prompt intervention and through collaboration with the rheumatologist.
