Digital mucous cysts (DMC) are common benign myxoid cysts typically located on the fingers and toes. Recently, dermoscopic patterns of DMC were reported. However, only a small number of cases were described in the published work; therefore, information on this topic is scarce in the published work. We investigated dermoscopic patterns of histopathologically diagnosed DMC. In total, 23 cases were enrolled in this study. Polarized dermoscopy revealed vascular patterns in 13 cases (56.5%), with arborizing vascular patterns, dotted vessels, linear vessels and polymorphous vessels in eight (34.8%), three (13.0%), one (4.3%) and one (4.3%) case, respectively. Red-purple lacunas, ulceration, nail dystrophy and white shiny structures were detected in five (21.7%), two (8.7%), seven (30.4%) and six cases (26.1%), respectively. We report the largest case series regarding dermoscopic features of DMC to date. Dermoscopy can be used as a helpful adjuvant and non-invasive tool in the diagnosis of DMC.

Psoriasis is a chronic recurrent inflammatory skin disease with prevalence of 1–3%. Nail psoriasis affects 10–90% of patients with plaque psoriasis.The aim of the article is to review the literature for the correlation between nail psoriasis and psoriatic arthritis (PsA) to provide rheumatologists a short review on features of nail psoriasis, methods of their assessment and possible clinical repercussions.The PubMed database was searched using the key words ‘nail psoriasis’ and ‘psoriatic arthritis’. Psoriasis involving the nail matrix shows up as changes such as pitting, Beau lines, leukonychia, red spots in the lunula, or nail plate crumbling. Nail bed psoriasis manifests as onycholysis, oil drops (or salmon patches), dyschromia, splinter hemorrhages, or subungual hyperkeratosis. Nail psoriasis and psoriatic lesions in the gluteal cleft and on the scalp usually accompany PsA, especially in adult men.

“…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].…”

Objective: The objective of this study is to evaluate the link between nail fold vessel resistive index (NVRI) measured by ultrasound (US) and capillary loops diameters measured using nailfold videocapillarascopy (NVC), and to assess the morphological appearance of the nail bed in patients with psoriatic nail disease (PND) as compared with healthy controls (HCs).Material and methods: This study was conducted in patients with PND and HCs. General demographic data were collected and clinical assessments were performed for all subjects. The nail plate thickness (NPT) was measured on gray scale using US. The NVRI was measured using color Doppler (CD) US. The measurements of the apical, arterial, venous limb diameters and morpho-structural changes (tortuous, cross-linked capillaries) were assessed using NVC.Results: Thirty-four patients with PND and 15 HCs were enrolled in this study. The two groups were matched for age and body mass index (BMI). Patients with PND had higher NPT and NVRI in comparison with HCs [(20 (17-23) vs 14 (14-15), p<0.001), (0.55 (0.51-0.61) vs 0.43 (0.38-0.49), p<0.001), respectively]. A higher proportion of patients with PND had tortuous capillaries than HCs (62% and 20% respectively, p=0.005). The mean NVRI was higher in patients with PND who had tortuous capillaries than patients who did not have tortuous capillaries (0.58 (0.7) and 0.52 (0.09), respectively p=0.033).Conclusion: Microvascular changes can be detected easily using non-invasive methods such as US and NVC. These methods can provide an objective data to better assess PND.
