Dermoscopy of nail fold and elbow in the differential diagnosis of early psoriatic arthritis sine psoriasis and early rheumatoid arthritis

Abstract: Differentiation between psoriatic arthritis (PsA) sine psoriasis and rheumatoid arthritis (RA) may be a challenge, especially in the early stages, hence the need for new instrumental markers to assist their diagnosis. In this study, we investigated possible dermoscopic differences in vascular appearance of nail fold and elbow (a classic site of repeated trauma) in these two conditions. Fifteen patients with PsA sine psoriasis, 12 patients with RA and 12 controls were included in the study. Regarding the nail f… Show more

“…However, sometimes it is extremely difficult to distinguish PsA (especially if it is sine psoriasis) from rheumatoid arthritis (RA). Dermoscopy may be a useful supportive tool for differentiating early PsA from RA [23]. …”

“…Errichetti et al have highlighted the usefulness of nail fold and elbow dermoscopy to differentiate early PsA sine psoriasis from early RA in terms of typical vascular findings such as dotted vessels [41]. Cross-linked and tortuous capillaries representing microvascular changes have been observed in a number of studies in patients with psoriasis [11,16,18,40].…”
