Lichen striatus associated with psoriasis vulgaris treated with oral acitretin.

Lichen striatus (LS) is an uncommon dermatosis of unknown etiology that presents as a continuous or interrupted linear band of pink, tan, red or skin-colored papules in a blaschkoid distribution. The lesions are generally solitary and unilateral, but unusual extensive cases with multiple and bilateral lesions have been also described. Albeit LS is typically an asymptomatic and self-limited dermatosis, it may cause a significant psychological distress in some patients, thus requiring an appropriate therapy. Topical steroid is the most commonly used treatment but it is not always effective. We report a case of LS unresponsive to topical steroid therapy associated with psoriasis vulgaris successfully treated with oral acitretin

Plaque-Type Psoriasis Treated with Calcipotriene Plus Betamethasone Dipropionate Aerosol Foam: A Prospective Study on Clinical and Dermoscopic Predictor Factors in Response Achievement and Retention

Introduction: Little information on possible local factors that can influence the achievement and retention of response of plaque-type psoriasis to calcipotriene plus betamethasone dipropionate aerosol foam is available. The aim of this study was to assess possible correlations between baseline clinical/dermoscopic features of psoriatic plaques and therapeutic response, and between residual dermoscopic findings in clinically improved/healed lesions and post-treatment relapse. Methods: For each target lesion, we calculated the local psoriasis severity index and assessed dermoscopic findings at baseline and at the end of a 4-week treatment, correlating the therapeutic outcome with the initial clinical and dermoscopic features. The lesions were also followed for a 4-week post-treatment period, and possible associations between relapse and (1) baseline clinical/dermoscopic features and (2) dermoscopic findings detected at the end of the treatment were assessed. Results: A total of 105 lesions from 35 patients were included in the analysis. After 4\ua0weeks of therapy, 13 lesions showed no/limited improvement, while partial and optimal response were observed in 51 and 41 plaques, respectively. Poor outcomes were correlated with both legs localization\ua0and degree of lesion infiltration at baseline. Similarly, presence of globular vessels at baseline dermoscopy was more commonly associated with no/limited response and lesions on the legs, particularly those showing resistance to treatment. A correlation was also found between dotted vessels on the baseline dermoscopic examination and good outcomes (partial/optimal response). After a 4-week post-treatment follow-up, 58.7% of the lesions achieving improvement at the end of the therapy showed relapse, with a correlation between recurrence and vessel persistence\ua0on dermoscopy at the end of the therapy. Conclusion: Clinical response of plaque-type psoriasis to calcipotriol/betamethasone dipropionate spray foam may be adversely affected by the degree of infiltration of lesions at baseline and by legs\ua0localization, and the presence of globular vessels at the baseline dermoscopic assessment is related to poor outcomes. A significant post-treatment relapse rate was observed, and persistence of vascular changes on dermoscopy seems to play a role in promoting disease recurrence

Dermoscopy for venereologists: an update on patterns of tumors, inflammatory and infectious diseases of the genitalia, and tips for differential diagnosis

Introduction: Dermoscopy is an integrative part of clinical dermatologic examination. For clinicians mainly dealing with genital dermatoses and other venereal diseases, the differential diagnosis includes a broad spectrum of neoplastic, inflammatory, and infectious entities. Dermoscopy might have a valuable role to enhance the clinical differential diagnosis and help avoid some biopsies done for diagnostic purposes. Although the dermoscopic patterns of most tumors and inflammatory diseases of the trunk/face have been described, their manifestations on genital areas are less elucidated. We aimed to provide a succinct summary of existing data on dermoscopy of dermatologic diseases on genital areas. Methods: A literature search was performed on PubMed using the terms dermoscopy OR dermatoscopy OR videodermoscopy OR video dermoscopy AND genital. All studies reporting on dermoscopic findings of at least one case of a dermatologic disease on genital areas were included in the review. Unless otherwise indicated, 710 was the magnification used in the reported studies. The main outcome was to describe the dermoscopic feature of each disease. Results: A total of 31 articles were identified and analyzed. They included single case reports and case series. The described entities were categorized into anatomical variants, vascular and lymphatic lesions, tumors, inflammatory disorders, and infectious conditions. Conclusion: In diseases of the genital area, dermoscopic findings can be highly diagnostic and might establish a confident diagnosis. Limitation is that most of the criteria are based on case series, and few of them have been validated

Dermoscopic and Clinical Response Predictor Factors in Nonsegmental Vitiligo Treated with Narrowband Ultraviolet B Phototherapy: A Prospective Observational Study

Introduction: Few data on possible local factors that can influence the achievement of response in nonsegmental vitiligo (NSV) treated with narrowband ultraviolet B (Nb-UVB) phototherapy are available. Our objective is to evaluate possible correlations between therapeutic outcomes and dermoscopic and local (lesional) clinical findings of vitiligous lesions undergoing Nb-UVB phototherapy to find positive and/or negative response predictor factors to such treatment. Methods: For each target patch, we calculated the extension area using a computer-aided method and assessed dermoscopic and local (lesional) clinical findings at baseline. After 30 phototherapy sessions (twice weekly), surface area of the lesions was reevaluated to assess clinical improvement, correlating the therapeutic outcome with initial clinical and dermoscopic features. Results: A total of 70 lesions were finally included in the study. At the end of therapy, 18 patches (25.7%) achieved improvement, and the presence of perifollicular pigmentation on baseline dermoscopic examination was found to be associated with a 12-fold higher probability of having a positive therapeutic outcome. Similarly, face localization was also correlated with clinical amelioration, with a sevenfold higher probability for improvement. No association (p > 0.05) between therapeutic outcomes (either good or poor) and other dermoscopic or local clinical variables (including leukotrichia) was observed. Conclusions: Therapeutic response of vitiligo to Nb-UVB phototherapy may be positively affected by local features of the lesions, i.e., face localization and presence of perifollicular pigmentation on baseline dermoscopic examination, which might be considered as positive response predictor factors to optimize treatment of vitiligo

Knuckle pads mimic early psoriatic arthritis

Knuckle pads or Garrod\u2019s nodes are a rare, non-inflammatory condition. They consist of benign, well-circumscribed fibro-adipose tissue over the small joints of hands and feet. Knuckle pads may be under-diagnosed and mistaken for early arthritis. The rheumatologist should perform an accurate differential diagnosis in which he can be helped by ultrasound and by other colleagues, such as the dermatologist. Ultrasound is considered useful in the assessment of the thickening of the subcutaneous tissue, located usually on the extensor site of proximal interphalangeal and metacarpophalangeal hand joints. Dermoscopy may play a role in detecting epidermal and dermal changes. We hereby report the case of a female patient with knuckle pads mimicking psoriatic arthritis

Autologous micrografts and methotrexate in plantar erosive lichen planus: healing and pain control. A case report

Erosive lichen planus is an uncommon variant of lichen planus. We report a case of long-standing and refractory plantar ELPs causing disabling and opiate-resistant pain treated with 'classic' meshed skin graft combined with RigeneraVR micrografts. After approximately 9 months follow-up, no clinical recurrence or pain were observed. Erosive lichen planus (ELP) is an uncommon variant of lichen planus, involving oral cavity and genitalia and, less often plantar areas, where it usually presents with chronic erosions of the soles, along with intense, disabling pain and progressive loss of toenails. An abnormal immune cellular response (CD8+ lymphocytes and macrophages) and the consequent altered production of multiple mediators (interleukin-12, interferon-gamma, tumor necrosis factor-alpha, RANTES and MMP-9), seem to play a crucial role in the pathogenesis, although the etiology remains uncertain. From a histological point of view, ELP shows keratinocyte apoptosis, intense inflammatory response and basal epithelial keratinocytes TNF-alpha overexpression. Several therapies have been proposed, with variable and controversial results. While topical corticosteroids and topical calcineurin inhibitors are the treatments of choice for localized forms, short pulses of systemic glucocorticoids, phototherapy, and systemic immunosuppressants are recommended for generalized cases. Surgery has been reported as a possible therapeutic option in refractory and stable cases with localized lesions, either alone or with cyclosporine. Herein, we report a case of longstanding and refractory plantar ELPS causing disabling and opiate-resistant pain treated with 'classic' meshed skin graft combined with RigeneraVR micrografts
