ABSTRACT
Alopecia areata is an autoimmune form of non-scarring hair loss. It is usually characterized by limited areas of hair loss. However, the disease may progress to complete scalp and body hair loss (alopecia totalis, alopecia universalis). In patients with alopecia areata hair loss significantly impacts the quality of life. Children and adolescents with alopecia areata often experience bullying, including physical aggression. The disease severity evaluation tools used in clinical practice are: the Severity of Alopecia Tool (SALT) score and the Alopecia Areata Scale (AAS). A SALT score equal to or greater than 20 constitutes a commonly accepted indication for systemic therapy in alopecia areata. When using the AAS, moderate to severe alopecia areata should be considered a medical indication for systemic treatment. Currently, the only two EMA-approved medications for alopecia areata are baricitinib (JAK 1/2 inhibitor) for adults and ritlecitinib (JAK 3/TEC inhibitor) for individuals aged 12 and older. Both are EMA-approved for patients with severe alopecia areata. Other systemic medications used off-label in alopecia areata include glucocorticosteroids, cyclosporine, methotrexate and azathioprine. Oral minoxidil is considered an adjuvant therapy with limited data confirming its possible efficacy. This consensus statement is to outline a systemic treatment algorithm for alopecia areata, indications for systemic treatment, available therapeutic options, their efficacy and safety, as well as the duration of the therapy.

The introduction of immune checkpoint inhibitors (ICIs) opened a new era in oncologic therapy. The favourable profile of ICIs in terms of efficacy and safety can be overshadowed by the development of immune-related adverse events (irAEs). Dermatologic irAEs (dirAEs) appear in about 40% of patients undergoing immunotherapy and mainly include maculopapular, psoriasiform, lichenoid and eczematous rashes, auto-immune bullous disorders, pigmentary disorders, pruritus, oral mucosal lesions, hair and nail changes, as well as a few rare and potentially life-threatening toxicities. The EADV task force Dermatology for Cancer Patients merged the clinical experience of the so-far published data, incorporated the quantitative and qualitative characteristics of each specific dirAEs, and released dermatology-derived, phenotype-specific treatment recommendations for cutaneous toxicities (including levels of evidence and grades of recommendation). The basic principle of management is that the interventions should be tailored to serve the equilibrium between patients' relief from the symptoms and signs of skin toxicity and the preservation of an unimpeded oncologic treatment.

BACKGROUND: Squamous cell carcinoma of the lip accounts for 20% of all oral carcinomas. Its diagnosis may be challenging because it clinically resembles actinic cheilitis and inflammatory lesions of the lips. OBJECTIVES: To determine clinical and dermatoscopic predictors of squamous cell carcinoma of the lip vs. other lip lesions. METHODS: Multicentre retrospective morphological study, including histologically confirmed cases of squamous cell carcinoma of the lip and controls consisting of actinic cheilitis and inflammatory lesions of the lips. Clinical and dermatoscopic images were evaluated for the presence of predefined criteria. Crude and adjusted odds ratios and corresponding 95% confidence intervals were calculated by univariate and multivariate logistic regression respectively. RESULTS: A total of 177 lip lesions were evaluated, 107 (60.5%) were squamous cell carcinomas and 70 (39.5%) were controls. The most frequent dermatoscopic criteria of lip squamous cell carcinoma were scales (100%), white halos (87.3%) and ulceration (79.4%). The majority of squamous cell carcinomas displayed polymorphic vessels (60.8%), with linear (68.6%) and hairpin (67.6%) being the most frequent types. Multivariate logistic regression analysis showed that clinical predictors of lip squamous cell carcinoma were exophytic appearance and clinical hyperkeratosis, with 43-fold and 6-fold higher probability respectively. White clods and ulceration in dermoscopy presented a 6-fold and 4-fold increased risk for squamous cell carcinoma respectively. CONCLUSIONS: A scaly lesion with exophytic growth, dermatoscopically displaying white clods, ulceration and linear and hairpin vessels is very likely a squamous cell carcinoma of the lip.

BACKGROUND: Real-world data in patients with moderate psoriasis treated with apremilast is limited. OBJECTIVES: To evaluate the effectiveness and safety of apremilast in bio-naïve patients with moderate psoriasis in real-world clinical settings. METHODS: This was a 52-week multicenter, observational, prospective study of adult outpatients with moderate psoriasis {[10% < body surface area < 20% or 10 < psoriasis area severity index (PASI) < 20] and 10 < dermatology quality of life index (DLQI) < 20} initiated on apremilast ≤7 days before enrollment. Missing data were imputed using the last observation carried forward method. RESULTS: A total of 287 eligible patients (median age: 54.2 years; median psoriasis duration: 9.8 years) were consecutively enrolled. At baseline, the median DLQI and PASI scores were 12.0 and 11.8, respectively. The 52-week DLQI ≤ 5 and PASI75 response rates were 68.3% and 61.0%. At 52 weeks, 70.8% and 72.7% of the patients shifted from moderate/severe/very severe to clear/minimal scalp and palmoplantar psoriasis involvement, respectively; the pruritus severity state improved in 67.2%. The 52-week Kaplan-Meier estimated drug continuation rate was 85.3%. The adverse drug reaction rate was 19.9%. CONCLUSIONS: Apremilast is a safe and effective treatment for bio-naïve patients with moderate psoriasis and specific psoriasis manifestations.

BACKGROUND: Apremilast is an oral phosphodiesterase-4 inhibitor indicated for patients with moderate-to-severe chronic plaque psoriasis and active psoriatic arthritis. OBJECTIVES: To examine the effectiveness of apremilast on Dermatology Life Quality Index (DLQI), Psoriasis Area and Severity Index (PASI) and nail, scalp and palmoplantar involvement, when administered prior to biologics. METHODS: This 52-week real-world study included biologic-naive adults with moderate psoriasis (psoriasis-involved body surface area 10% to <20%, or PASI 10 to <20 and DLQI 10 to <20). Apremilast was initiated ≤7 days before enrolment. Data from the first 100 eligible patients who completed 24 weeks (W24) of observation (or were prematurely withdrawn) are presented in this interim analysis using the last-observation-carried-forward imputation method. RESULTS: Eligible patients (mean age: 49.9 years; 71.0% males; median disease duration: 8.0 years) were consecutively enrolled between April and October 2017, by 18 dermatology specialists practising in hospital outpatient settings in Greece. Baseline DLQI (median: 12.0) and PASI (median: 11.7) scores improved (P < 0.001) at all postbaseline timepoints (Weeks 6, 16 and 24; W24 median decreases: 9.0 and 9.4 points respectively). At W24, DLQI ≤5, DLQI 0 or 1, and PASI-75 response rates were 63.0%, 25.0% and 48.0% respectively. The Nail Psoriasis Severity Index score in patients with baseline nail involvement (n = 57) decreased at all postbaseline timepoints (P < 0.001; W24 median decrease: 20.0 points). At W24, 50.0% and 51.7% of patients with baseline scalp (n = 76) and palmoplantar (n = 29) involvement respectively achieved postbaseline Physician's Global Assessment (PGA) score of 0 or 1 if baseline score was ≥3, or 0 if baseline score was 1 or 2. The adverse drug reaction rate was 21.0% (serious: 2.0%). CONCLUSIONS: These interim results indicate that through 24 weeks, apremilast improved quality of life and reduced disease severity in biologic-naive patients with moderate plaque psoriasis, while demonstrating safety consistent with the known safety profile.

BACKGROUND: Over the last few years, several articles on dermoscopy of non-neoplastic dermatoses have been published, yet there is poor consistency in the terminology among different studies. OBJECTIVES: We aimed to standardize the dermoscopic terminology and identify basic parameters to evaluate in non-neoplastic dermatoses through an expert consensus. METHODS: The modified Delphi method was followed, with two phases: (i) identification of a list of possible items based on a systematic literature review and (ii) selection of parameters by a panel of experts through a three-step iterative procedure (blinded e-mail interaction in rounds 1 and 3 and a face-to-face meeting in round 2). Initial panellists were recruited via e-mail from all over the world based on their expertise on dermoscopy of non-neoplastic dermatoses. RESULTS: Twenty-four international experts took part in all rounds of the consensus and 13 further international participants were also involved in round 2. Five standardized basic parameters were identified: (i) vessels (including morphology and distribution); (ii) scales (including colour and distribution); (iii) follicular findings; (iv) 'other structures' (including colour and morphology); and (v) 'specific clues'. For each of them, possible variables were selected, with a total of 31 different subitems reaching agreement at the end of the consensus (all of the 29 proposed initially plus two more added in the course of the consensus procedure). CONCLUSIONS: This expert consensus provides a set of standardized basic dermoscopic parameters to follow when evaluating inflammatory, infiltrative and infectious dermatoses. This tool, if adopted by clinicians and researchers in this field, is likely to enhance the reproducibility and comparability of existing and future research findings and uniformly expand the universal knowledge on dermoscopy in general dermatology. What's already known about this topic? Over the last few years, several papers have been published attempting to describe the dermoscopic features of non-neoplastic dermatoses, yet there is poor consistency in the terminology among different studies. What does this study add? The present expert consensus provides a set of standardized basic dermoscopic parameters to follow when evaluating inflammatory, infiltrative and infectious dermatoses. This consensus should enhance the reproducibility and comparability of existing and future research findings and uniformly expand the universal knowledge on dermoscopy in general dermatology.

BACKGROUND: Topical methyl aminolevulinate photodynamic therapy (MAL-PDT) with 3 h incubation is recommended as a field directed treatment. Skin pretreatment with ablative CO2 fractional laser (AFXL) prior to MAL-PDT enhances drug penetration and could minimize incubation time. OBJECTIVES: To evaluate and compare the safety and the preventive effect in the development of new non-melanocytic skin cancers (NMSCs) of AFXL-assisted MAL-PDT with 1-h incubation with that of conventional MAL-PDT in patients with clinical and histological signs of field cancerization. METHODS: Forty-two patients with two mirror cancerized areas of face or scalp were randomized to field treatment with 1-h incubation AFXL-assisted PDT or conventional PDT (CPDT). All patients underwent two treatment sessions 1 week apart. Irradiation was performed using a red light-emitting diode lamp at 37 J/cm2 . Patients were followed up at 3, 6, 9 and 12 months for the evaluation of development of new NMSCs lesions. RESULTS: All patients completed the study. There was no statistically significant difference with respect to the total number of new actinic keratoses at any point of follow-up as well as to the mean time of occurrence of new lesions between treatment fields. Both treatment regimens were safe and well tolerated. CONCLUSION: Ablative CO2 fractional laser pretreatment may be considered as an option for reducing photosensitizer occlusion time while providing the same preventative efficacy as CPDT in patients with field-cancerized skin.

BACKGROUND: Mammary Paget's disease (MPD) is a rare intraepidermal adenocarcinoma of the nipple-areola complex, associated with an underlying breast cancer in approximately 90% of cases. Delayed diagnosis of MPD is common. Its dermoscopic features have been ill defined in the literature. OBJECTIVES: To determine the clinical and dermoscopic features of MPD versus other dermatologic entities that involve nipple and areola. METHODS: Members of the IDS were invited to submit any case of histologically confirmed MPD, as well as other benign and malignant dermatoses that involve the nipple and areola complex. A standardized evaluation of the dermoscopic images was performed and the results were statistically analyzed. RESULTS: Sixty-five lesions were included in the study, 22 (33.8%) of them MPD and 43 (66.2%) controls. The most frequent dermoscopic criteria of MPD were white scales (86.4%) and pink structureless areas (81.8%), followed by dotted vessels (72.7%), erosion/ulceration (68.2%) and white shiny lines (63.6%). The multivariate analysis showed that white scales and pink structureless areas were significant predictors of MPD, posing a 68-fold and a 31-fold probability of MPD, respectively. Split of the population into pigmented and non-pigmented lesions showed that in pigmented MPD, pink structureless areas, white lines and grey granules and dots are positive predictors of the disease. Among non-pigmented lesions, pink structureless areas, white lines, erosion/ulceration and white scales served as predictors of MPD. CONCLUSIONS: The most frequent profile of an individual with MPD is an elderly female with unilateral, asymptomatic, erythematous plaque of the nipple, dermoscopically displaying pink structureless areas, fine white scales, dotted and a few short linear vessels. In case of pigmentation we may also observe brown structureless areas and pigmented granules. LIMITATIONS: Small sample size, retrospective design.

BACKGROUND: The dermoscopic features of superficial basal cell carcinoma (sBCC) and Bowen's disease (BD) have been extensively investigated, and dermoscopy was shown to significantly improve their recognition. However, incorrectly diagnosed cases still exist, with a considerable number of sBCCs dermoscopically interpreted as BD. Our aim was to investigate the dermoscopic variability in sBCC and BD on different anatomic sites, to identify potent dermoscopic predictors for each diagnosis and to investigate the potential source of the inaccurate clinico-dermoscopic diagnosis of some sBCCs. METHODS: Dermoscopic images of histopathologically diagnosed sBCC and BD were evaluated by three independent investigators for the presence of predefined criteria. Subsequently, three independent investigators with expertise in dermoscopy classified the tumours as sBCC or BD based on the dermoscopic image. Diagnostic accuracy scores were calculated and crude and adjusted odds ratios, and 95% confidence intervals were calculated by univariate and conditional multivariate logistic regression, respectively. RESULTS: A total of 283 lesions were included in the study (194 sBCCs and 89 BD). The main dermoscopic predictors of BD were dotted vessels (7.5-fold) and glomerular vessels (12.7-fold). The presence of leaf-like areas/spoke-wheel areas/concentric structures (OR = 0.027) and arborizing vessels (OR = 0.065) has predicted sBCC. Multivariate risk factors for sBCC misclassification were the location on lower extremities (OR = 5.5), the presence of dotted vessels (OR = 59.5) and the presence of large ulceration (OR = 6.4). In contrast, the presence of brown-coloured pigmentation was a protective predictor for misdiagnosis (OR = 0.007). Finally, a subgroup analysis of lesions located on lower extremities revealed two additional potent predictors of sBCC: superficial fine telangiectasia (SFT) and whity shiny blotches/strands. CONCLUSIONS: Dotted and glomerular vessels are strong predictors of BD. When located on the lower extremities, sBCC may also display dotted vessels, rendering its recognition problematic. On the latter anatomic site, clinicians should consider SFT and whity shiny blotches/strands as additional sBCC predictors.

BACKGROUND: Acquired naevi often present in childhood and increase in number and size during early and middle life. As naevi represent potential mimickers of melanoma, the knowledge of their epidemiologic and morphologic characteristics is essential. OBJECTIVE: In this study, we intend to determine the prevalence of dermoscopic patterns of naevi, as well their association with environmental and constitutional factors. METHODS: Cross-sectional data derived from a population-based cohort of children and adolescents aged 6-18 years, from 12 different schools in Thessaloniki, Greece. For each participant, a consent form and a questionnaire were completed, which included data on age, sex, phototype, sun sensitivity, sun exposure, sunscreen use and previous sunburn history. All naevi, their body distribution, and their dermoscopic patterns were recorded. RESULTS: Two thousand and five hundred and five (2505) subjects were enrolled into the study (47.8% males and 52.2% females). The mean number of MN counted in a single person was 29.11 (SD = ±23.863). TNC increased continuously with higher age. Males were found to have a significantly increased number on the trunk (11.7 ± 11.2 and 10.0 ± 8.7, respectively, P < 0.001) and face and neck (6.2 ± 5.3 and 5.1 ± 4.3, respectively, P < 0.001) while females on the upper (10.3 ± 10.1 and 9.3 ± 9.4, respectively, P = 0.008) and lower extremities (2.8 ± 3.4 and 2.5 ± 3.2, respectively, P = 0.008). Globular pattern was the most frequent dominant pattern in lower age groups, and its percentage fell as age increased. On the contrary, the reticular pattern was more often documented in individuals in adolescence. CONCLUSION: This first study of MN in our young population aims to be the basis of further investigation for the MM preventive policy of our state.

Dermoscopy has been documented to increase the diagnostic accuracy of clinicians evaluating skin tumours, improving their ability to detect skin cancer and better recognize benign moles. However, dermoscopically 'false-positive' and 'false-negative' tumours do exist. False-positive diagnosis usually leads to unnecessary excisions. False-negative diagnosis is much more dangerous, as it might result in overlooking a cancer, with severe undesirable consequences for the patient and the physician. Therefore, management strategies should mainly focus on addressing the risk of dermoscopically false-negative tumours. The most frequent benign tumours that might acquire dermatoscopic characteristics suggestive of malignancy are seborrhoeic keratosis (SK), including solar lentigo, melanoacanthoma, irritated, clonal and regressive SK, angioma (mainly thrombosed angioma and angiokeratoma), dermatofibroma, benign adnexal tumours and naevi (Clark, Spitz, recurrent, combined, sclerosing). The most useful clues to recognize these tumours are the following: solar lentigo - broad network; melanoacanthoma - sharp border; irritated SK - regularly distributed white perivascular halos; clonal SK - classic SK criteria; regressive SK - remnants of SK; targetoid haemosiderotic haemangioma - dark centre and reddish periphery; thrombosed angioma - sharp demarcation; angiokeratoma - dark lacunae; atypical dermatofibromas - palpation; follicular tumours - white colour; sebaceous tumours - yellow colour; Clark naevi - clinical context; Spitz/Reed naevi - age; combined naevi - blue central area; recurrent naevi - pigmentation within the scar; sclerosing naevi - age and location on the upper back; blue naevi - history. Malignant tumours that might mimic benign ones and escape detection are melanoma (in situ, nevoid, spitzoid, verrucous, regressive, amelanotic), squamous cell carcinoma (mainly well-differentiated variants) and rarely basal cell carcinoma (non-pigmented variants). The most useful clues to recognize the peculiar melanoma subtypes are as follows: melanoma in situ - irregular hyperpigmented areas; nevoid melanoma - history of growth; spitzoid melanoma - age; verrucous melanoma - blue-black sign; regressive melanoma - peppering or scar-like depigmentation; amelanotic melanoma - pink colour, linear irregular vessels, dotted vessels. In this article, we summarized the most frequent dermoscopic variations of common skin tumours that are often misinterpreted, aiming to assist clinicians to reduce the number of false diagnoses.

Spitzoid lesions represent a challenging and controversial group of tumours, in terms of clinical recognition, biological behaviour and management strategies. Although Spitz naevi are considered benign tumours, their clinical and dermoscopic morphological overlap with spitzoid melanoma renders the management of spitzoid lesions particularly difficult. The controversy deepens because of the existence of tumours that cannot be safely histopathologically diagnosed as naevi or melanomas (atypical Spitz tumours). The dual objective of the present study was to provide an updated classification on dermoscopy of Spitz naevi, and management recommendations of spitzoid-looking lesions based on a consensus among experts in the field. After a detailed search of the literature for eligible studies, a data synthesis was performed from 15 studies on dermoscopy of Spitz naevi. Dermoscopically, Spitz naevi are typified by three main patterns: starburst pattern (51%), a pattern of regularly distributed dotted vessels (19%) and globular pattern with reticular depigmentation (17%). A consensus-based algorithm for the management of spitzoid lesions is proposed. According to it, dermoscopically asymmetric lesions with spitzoid features (both flat/raised and nodular) should be excised to rule out melanoma. Dermoscopically symmetric spitzoid nodules should also be excised or closely monitored, irrespective of age, to rule out atypical Spitz tumours. Dermoscopically symmetric, flat spitzoid lesions should be managed according to the age of the patient. Finally, the histopathological diagnosis of atypical Spitz tumour should warrant wide excision but not a sentinel lymph-node biopsy.

BACKGROUND: Individuals with medical history of non-melanoma skin cancers (NMSCs) usually develop multiple and/or recurrent malignant lesions around the site of the primary neoplasm. The latter represents the clinical expression of the 'field cancerization' theory; supporting the presence of multiple malignant clones of dysplastic keratinocytes over the entire epithelium that potentially can progress into clinical lesions. Taking into consideration that the burden of NMSCs on public health and health-care cost is high, adequate control of recurrences and management of field change is challenging. OBJECTIVES: To compare the safety and efficacy of daylight photodynamic therapy (DL-PDT) vs. conventional photodynamic therapy (C-PDT) in the prevention of occurrence of new NMSCs in patients with clinical and histological signs of actinic field damage. METHODS: Twenty-six patients, with personal history of NMSCs on the face or scalp and actinic keratosis (AK) on the same fields, were randomized for DL-PDT on one side and C-PDT on the other. For a 12-month period, individuals were clinically evaluated for development of new NMSCs. RESULTS: The total number of new AKs and the mean time of their development did not significantly differ between the treated sides. Local adverse events were more intense with C-PDT, and patients' preference was more for DL-PDT compared to C-PDT. CONCLUSIONS: The current findings suggest equal preventive potential of DL-PDT vs. C-PDT against the formation of new NMSCs in patients exhibiting actinic field damage.

BACKGROUND: The scalp is a frequent and difficult-to-treat localization of psoriasis. Little evidence exists regarding the use of biologic agents in recalcitrant cases of scalp psoriasis that are resistant to other treatment options. OBJECTIVES: To evaluate and compare the efficacy of currently available biologic agents (infliximab, etanercept, adalimumab, ustekinumab) in the treatment of scalp symptoms in patients suffering from moderate to severe plaque psoriasis. MATERIALS AND METHODS: This retrospective cohort study consisted of a review of the database of all psoriasis patients who suffered from scalp symptoms and received biologic treatment between January 2012 and December 2014. The patients were divided into four groups based on the drug administered. Scalp psoriasis severity was assessed by the Psoriasis Scalp Severity Index (PSSI) at baseline and at weeks 4, 12, 24 and 48. Psoriasis severity was evaluated with the Psoriasis Area and Severity Index (PASI) at the same time points. RESULTS: In total, 145 patients were enroled in the study (infliximab n = 35, etanercept n = 30, adalimumab n = 39, ustekinumab n = 41). At week 4, the infliximab group achieved a 74% mean decrease in the PSSI (ΔPSSI), followed by mean decreases of 61.7%, 53.1% and 53.7% in the ustekinumab, etanercept and adalimumab groups respectively. The differences in the ΔPSSI were lower at week 48: ustekinumab 94.9%, infliximab 94.3%, etanercept 83.1% and adalimumab 89.0%. The PASI score improved sufficiently in all treatment groups. Infliximab and ustekinumab exhibited greater efficacy at weeks 4 and 12. This difference was not as prominent as that revealed by the PSSI. At week 48, the differences in the ΔPASI were barely statistically significant (P = 0.048). CONCLUSIONS: All four biologic agents yielded significant improvement in both scalp and skin lesions. Ustekinumab and infliximab exhibited the greatest efficacy, which was clinically meaningful from the early stages of the study. Adalimumab and etanercept followed, yielding satisfactory improvement rates.

BACKGROUND: Ultraviolet radiation plays an important role in the pathogenesis of non-melanoma skin cancer. Outdoor workers, including farmers, experience higher exposure levels compared to the general population. Available literature data suggest that occupational ultraviolet exposure represents an independent risk factor for squamous cell carcinoma; whereas for basal cell carcinoma (BCC) this association still remains unclarified. OBJECTIVES: To analyse the epidemiological, clinical and histological data of patients diagnosed with BCC, and correlate them with outdoor occupation in farmers. METHODS: Individuals with histologically diagnosed BCCs, between September 2013 and September 2015, were included in the study. Their medical data, including epidemiological, clinical and histological characteristics, were recorded and analysed in conjunction with the occupation. Farmers were identified based on their specific public health insurance. RESULTS: Three hundred and forty patients, with 542 BCCs were included in the study. One hundred and twenty (35.3%) were farmers. Mean age of farmers was lower than non-farmers (66.0 ± 9.1 years vs. 75 ± 6.6 years, Mann-Whitney U-test, P < 0.001). Farmers had a sixfold higher probability for exhibiting photodamaged skin (OR = 6.02, 95% CI: 3.66-9.90, P < 0.001). Farmer workers were more likely to exhibit infiltrative or morpheaform BCC, but less likely to develop superficial BCC. CONCLUSION: Our results indicate a higher risk of earlier development of more aggressive histological subtypes of BCCs in farmers. Photodamage was also more common in this group. Primary and secondary prevention strategies focusing on outdoor workers, including farmers, are mandatory.
