“…Although there was no systematic dermoscopic description of ILVEN, cobblestone pattern, cerebriform pattern and a large brown circle corresponding to exophytic epidermal structures have been described as developing primarily in ILVEN. 5 This is the first comparative dermoscopic study of the two clinically similar dermatoses with a distinct etiology. In our study, the significant dermoscopic feature of LS was gray granular pigmentation, whereas that of ILVEN was cerebriform pattern.…”

Dermoscopy of linear dermatosis along Blaschko's line in childhood: Lichen striatus versus inflammatory linear verrucous epidermal nevusDear Editor, Lichen striatus (LS) and inflammatory linear verrucous epidermal nevus (ILVEN), linear dermatosis along Blaschko's line, may mimic clinically; however, LS is a self-limited disease as compared with persistent ILVEN. 1-3 The differential diagnosis of these two entities, especially in early childhood, could be a diagnostic challenge, thus requiring histopathological analysis via skin biopsy. Our study was intended to determine the diagnostic usefulness of simple, non-invasive dermoscopy for differentiating between LS and ILVEN of children.We retrospectively reviewed dermoscopic features of 29 clinically indistinguishable linear skin eruptions that were histopathologically confirmed as LS and ILVEN. Dermoscopic examination was performed with a hand-held polarized-light dermoscope equipped with a digital camera (Dermlite Foto II Pro [3Gen, Houston, TX, USA] and Canon EOS 50D [Canon, Tokyo, Japan]). Statistical analysis was performed using SPSS *P < 0.05 between lichen striatus and epidermal nevus. ILVEN, inflammatory linear verrucous epidermal nevus; SD, standard deviation. e355

Background/Objectives Lichen striatus is a unilateral inflammatory dermatosis that rarely affects the nail unit. When the inflammation involves the nail unit, classic lichenoid nail changes are easily detectable, more often limited to only one portion of the nail. Usually the nail dystrophy coexists with periungual skin papules following Blaschko's lines, but it could also be an isolated feature. Because a nail unit biopsy presents difficulties in execution, especially in a child, the aim of our study has been to describe the nail unit dermoscopy features of lichen striatus hoping to provide a valid aid to clinicians in the diagnosing this rare disorder. Methods We reviewed the images of five pediatric patients with a clinical diagnosis of lichen striatus. Data about sex, age, localization, predisposing/triggering factors, and associated disorders are reported. Results The diagnosis of lichen striatus can be challenging as there are clinically overlapping features with related dermatoses. A common diagnostic pitfall occurs with inflammatory linear verrucous epidermal nevus and lichen planus. Involvement of only one part of the nail plate with linear longitudinal fissuring, ridging, and distal splitting, especially if seen with perionychial skin lesions, is characteristic of lichen striatus. Conclusions Nail lichen striatus is rare, and there is sparse published literature on it. When the changes in lichen striatus are limited to the nail, the diagnosis may easily be missed. We therefore believe that dermoscopy is an important diagnostic maneuver, which should be integrated into the evaluation of patients with potential lichen striatus, and in particular is helpful for clinicians unwilling or unable to perform a nail unit biopsy.

“…Dermoscopic features of many benign and malignant growths as well as many kinds of epidermal nevi like nevus sebaceous [5,6], hair follicle nevi [7], and nevus comedonicus [8] have been well described. However, the dermoscopic aspect of VEN has been the subject of only one original study in which Carbotti et al [2] analyzed 8 patients with VEN. Here, we identified clinical and dermoscopic features of 20 cases of VEN.…”

Background and Aim: Verrucous epidermal nevi are cutaneous hamartomas having many clinical variants. Dermoscopic features of verrucous epidermal nevus have rarely been investigated. We aimed to identify dermoscopic findings of the entity which will facilitate the diagnostic process by reducing the use of invasive diagnostic methods. Material and Methods: The study included the patients with histopathologically approved verrucous epidermal nevus. Clinical, dermoscopic and histopathological features of the patients were retrospectively reviewed and the findings identified were recorded. Dermoscopic examination was performed with a polarized-light handheld dermoscope with 10-fold magnification. Results: The most common dermoscopic features were thick brown circles, thick brown branched lines and terminal hairs. The most common vessel pattern was dotted vessels. Branched thick brown lines, brown globules, brown dots forming lines, serpiginous brown dots, white and brown exophytic papillary structures, fine scale, thick adherent scale and cerebriform structures were the other findings. Conclusion: We observed many vascular and non-vascular dermoscopic findings which have not been described previously for the entity. Dermoscopic examination of the verrucous epidermal nevi may lead more reliable clinical interpretation and thus it may reduce the need for histopathological investigation.
