“…Gomez-Quispe et al reported a higher incidence of incontinentia pigmenti (scattered brown discoloration and blue-gray dots) on dermoscopy of active scalp DLE [ 32 ]. Ankad et al stated that blue-gray dots/globules can be seen in the inactive period [ 44 ], while another study emphasized that blue-gray dots/globules can be seen in both active and inactive DLE [ 34 ]. Zychowska et al found that white scales, blue-gray dots/globules, and peripheral pigmentation were more common in DLE lesions present for more than 12 months [ 25 ].…”

Introduction: Dermoscopic findings are used to diagnose and evaluate disease activity in patients with cutaneous lupus erythematosus (CLE). Objectives: This study aimed to characterize the dermoscopic features of discoid LE (DLE) and LE tumidus (LET) by lesion duration and CLE Disease Area and Severity Index (CLASI) scores and to examine the dermoscopic findings of lesions in different locations in DLE patients. Methods: Dermoscopic findings (follicular features, perifollicular surface, interfollicular features, and vessel pattern) were assessed and lesion duration (≤12 and >12 months) and CLASI scores (grouped as mild or moderate) were calculated. DLE lesion locations were categorized as, non-scalp, scalp and lip. Results: Forty-eight dermoscopic images from 35 DLE and 4 LET patients were analyzed. The most common dermoscopic findings in non-scalp DLE were follicular keratotic plugs (82.8%) and white scales (69%). In scalp DLE (n=9), the most common findings were absent follicular openings (77.8%), white structureless areas (77.8%), and perifollicular scaling (66.7%). All LET patients had pink-white background and linear vessels. Follicular plugs, peripheral pigmentation, and polymorphous vessels were lower in patients with mild CLASI activity than moderate activity (P = 0.036, 0.039, and 0.019, respectively). Fibrotic white dots, honeycomb pigment pattern, and blue-gray dots/globules were lower in those with mild CLASI damage scores than moderate damage (P = 0.010, 0.010, and 0.020, respectively). Peripheral pigmentation was more common in patients with lesion duration ≤12 months, while blue-gray dots/globules were more common with lesion durations >12 months. Conclusions: Certain dermoscopic features may facilitate the differential diagnosis of DLE and LET.

More than meets the naked eye: an unusual psoriatic arthritis mimicry and the important role of dermoscopic examination

et al. 2021

Background Psoriatic arthritis (PsA) can manifest in various forms. This includes mimicry of other diseases. We describe an unusual mimicry of PsA. Case presentation We report a case of a middle-aged lady who presented with severe pain and morning stiffness over the small joints of the left hand for 3 months and painless deformity of the affected joints 1 year before. She was under treatment for pruritic rash over her ankles and knees for the past 1 year as well. Physical examination revealed a fixed flexion deformity, swelling and tenderness of the left ring and little fingers’ distal interphalangeal (DIP) joints. Left hand radiograph showed sclerotic joint margin, narrowed joint space and marginal osteophytes of the affected DIP joints. Dermoscopic examination showed red- violaceous, flat-topped papules and plaques with minimal scales on both ankles; hyperpigmented scaly plaques over both knees and vertical fingernail ridges. Serum autoimmune screening and inflammatory markers were unremarkable. Left ankle skin biopsy showed features consistent of psoriasis. PsA was diagnosed. Weekly titrated oral methotrexate and topical steroid were started. The patient showed significant improvement after 1 month of treatment. Conclusion PsA is a great mimicker. Dermoscopy is an accessible and valuable tool to assess skin lesions in greater detail. Clinicians should be aware of coexisting diseases or misdiagnosis when patients do not respond to treatment.
