Cutaneous manifestations of psoriatic arthritis and its dermoscopic findings

Abstract

A quick, inexpensive, non-invasive bolstering technique termed dermoscopy is being utilised to diagnose a number of inflammatory dermatoses and to evaluate nail fold vascular anomalies in a number of rheumatologic illnesses. Lesions with the most supporting evidence in this respect are psoriatic skin lesions since the combination of regularly distributed dotted vessels and widespread white scaling are a precise diagnostic findings. Furthermore, early nail psoriasis identification by dermoscopy, which is strongly connected to psoriatic arthritis, is advantageous as it makes certain dermoscopic manifestations, such as splinter haemorrhage, pitting, nail plate thickening and crumbling, distal onycholysis, leukonychia, oil spot sign, dilated hyponychial capillaries, and the pseudo-fiber sign, more visible. Thus, this review aims to emphasise the value of dermoscopy in the diagnosis of psoriasis and psoriatic arthritis (psA) in order to better discriminate PsA from other seronegative arthritis.
