Background
Extra-mammary Paget’s disease is a rare form of intraepithelial adenocarcinoma with a variable pattern of invasion, sometimes associated with distant malignancy. Vulvar Paget’s disease ...(VPD) represents 1% of all vulvar cancers. Standard treatment is surgical excision, however, the recurrence rate is high and surgery leads to anatomical, functional, and sexual morbidity. Some case series suggest efficacy of photodynamic (PDT) as treatment for this indication.
Objectives
Our aim was to assess the efficacy and tolerance of PDT in women suffering from VPD.
Materials & Methods
A retrospective study was conducted on all patients suffering from VPD, treated with PDT at six hospitals in France. Clinical data, histopathological reports at diagnosis, therapeutic history, PDT schedule, tolerance, and clinical response were reported.
Results
Thirteen women were included, with a mean age of 70.1 years. Ten women had an
in situ
disease, two had <1-mm dermal involvement, and one had adnexal involvement. All PDT courses were carried out using the same light source and photosensitizing agent. Complete response was achieved in two patients (15%) and partial response in five patients (38%). Five patients (38%) had stable disease and one (7%) had progressive disease. Ten of the 13 patients underwent pain evaluation; in six cases (60%), pain was described as moderate to intense.
Conclusion
PDT appears to be a therapeutic option for patients with VPD, with a response rate similar to that of other therapies usually recommended, such as surgery and imiquimod. There is a need to harmonise PDT procedures and pain assessment.

Merkel cell carcinoma (MCC) is frequently caused by the Merkel cell polyomavirus (MCPyV). Characteristic for these virus-positive (VP) MCC is MCPyV integration into the host genome and truncation of ...the viral oncogene Large T antigen (LT), with full-length LT expression considered as incompatible with MCC growth. Genetic analysis of a VP-MCC/trichoblastoma combined tumour demonstrated that virus-driven MCC can arise from an epithelial cell. Here we describe two further cases of VP-MCC combined with an adnexal tumour, i.e. one trichoblastoma and one poroma.
Whole-genome sequencing of MCC/trichoblastoma again provided evidence of a trichoblastoma-derived MCC. Although an MCC-typical LT-truncating mutation was detected, we could not determine an integration site and we additionally detected a wildtype sequence encoding full-length LT. Similarly, Sanger sequencing of the combined MCC/poroma revealed coding sequences for both truncated and full-length LT. Moreover, in situ RNA hybridization demonstrated expression of a late region mRNA encoding the viral capsid protein VP1 in both combined as well as in a few cases of pure MCC.
The data presented here suggest the presence of wildtype MCPyV genomes and VP1 transcription in a subset of MCC.

Nailfold capillaroscopy is recommended to diagnose primary or secondary Raynaud's phenomenon (RP). Capillaroscopy is normal in primary RP, which is the most frequent. Screening for RP capillary ...anomalies with nailfold dermoscopy has been promising.
To determine whether normal nailfold dermoscopy-based on the absence of five criteria that define a sclerodermic pattern-is able to predict normal capillaroscopy with good positive-predictive value (PPV).
Prospective, 2-phase (monocentre and multicentre) study on patients at first consultation for RP undergoing nailfold video capillaroscopy (NVC) and nailfold dermoscopy by two different 'blinded' trained observers, respectively, a vascular specialist and a dermatologist, not familiar with capillaroscopy. The five criteria noted were as follows: disorganization, megacapillaries, low capillary density, avascular areas and haemorrhages.
Based on 105 patients, the dermoscopy PPV for a normal NVC was 100% (p = 0.015), with 37.9% sensitivity, when no criterion was observed. Excluding haemorrhages, the PPV remained 100% (p < 0.0001), with sensitivity rising to 73.7% and 100% specificity.
Normal nailfold dermoscopy with the absence of four easy-to-observe criteria predicts normal NVC with an excellent PPV.

Background: In 2016, Nivolumab (N) and Pembrolizumab (P) have been registred for first line ECOG PS 0-1 adult patients with non-resecable or metastatic melanoma. The Brittany and ...Pays de la Loire Cancer Observatory has collected data on their real-life indications, current management, safety, efficacy and medico-economics Methods: All non opposing adult patients (pts) with advanced cutaneous melanoma who initiated a treatment with N (3 mg/kg q2w) or P (2 mg/kg q3w) in 2016 and 2017 were included. Minimum follow-up for survival was 12 months. Sex, age, mutation profile, lines of treatment, toxicities, response rate, survival and treatment cost have been collected. Results: 149 pts were treated by N and 201 pts by P with a median age of respectively 68 21-88 and 69 years 28-96. Of the 350 patients, 34% were at least 75 years and around 30% presented a BRAF mutation. The median duration of treatment was 4.9 months 0-34.6 for N and 4.2 0-35.8 for P (Not Significant NS). 65% of pts were treated in 1
st
line for N and 69% for P. 24% of the pts were treated in 2
nd
line for both treatments. 81% of the pts had a baseline PS of 0 or 1. All lines combined (first line for wt BRAF and first or second line for m BRAF melanoma), clinical benefit was 53% for N and 47% for P. Median OS was respectively 21.7 m for N and 22.8 m for P (NS). mPFS were respectively 6.4 m and 4.6 m (NS). 18% of pts presented grade III/IV toxicities with N and 17% with P. wt BRAF pts showed more grade III/IV toxicities than m BRAF pts (p = 0.046). For N, pts with grade III/IV toxicities showed better PFS (p = 0.051) and OS (p = 0.064). For both cohorts, PS ≥2, BRAF status and treatment line identified subgroup of pts with worsened PFS and OS 55% (24/44) of pts who stopped N or P because of death had a baseline PS of 0-1 showing PS alone is not sufficient to predict survival. Aggressive diseases (high metastasis rate, cerebro-meningeal metastasis, high tumor growth rate with any previous treatment) appear to be the worse candidates for immunotherapy. N and P courses during the 2 years costed 6.6 and 9.7 millions of euros respectively with approximatively 84% or 79% of this cost for N and P clinically benefitting pts. Conclusions: Immunotherapy in real-life setting in cutaneous advanced melanomas confirms literature’s data regarding clinical benefit, survival rate and safety profile and suggests to think about a composite predictive biomarker including BRAF status, ECOG PS, toxicity and treatment line.
This study aims at reporting 11 cases of carpal tunnel syndrome (CTS) occurring in patients on immunotherapy. The increasing use of immune checkpoint inhibitors in oncodermatology is associated with ...the appearance of immunologic adverse effects linked to nonspecific stimulation of the immune system. CTS has not been reported in this context. A retrospective multicenter review was performed on CTSs occurring on immunotherapy and confirmed with electroneuromyography. Data were collated from patients' files. Most of the time, CTS was severe, bilateral, with a motor deficit and confirmed axonal damage on electroneuromyography. In 4 cases, it was associated with rheumatological adverse effects (arthralgia/inflammatory synovitis). The most effective treatment appeared to be general corticosteroid therapy, even at low doses (<15 mg/d), or surgery. An imputability of the CTS of these patients to immunotherapy was considered due to the unusual intensity of the symptoms and the absence of other predisposing factors (diabetes and dysthyroidism well-controlled). Its combination with other immunologic adverse effects and the efficacy of general corticosteroid therapy suggests an immunologic origin. CTS is probably an immunologic adverse effect of immunotherapy. It is often severe or misleading in presentation and affects quality of life. The recognition of this adverse effect should make it possible to provide patients with appropriate care.
Objective
To determine whether a single session of botulinum toxin type A (BTA) injections into both hands more effectively decreases the frequency of systemic sclerosis–associated Raynaud's ...phenomenon (SSc‐RP) episodes than placebo.
Methods
This multicenter, randomized, double‐blind, placebo‐controlled, parallel‐group phase III trial in patients with SSc‐RP assessed the effect of 50‐unit BTA or placebo injections into the palms of both hands around each neurovascular bundle during 1 session in winter. The primary end point was the between‐group difference in the median change in the number of RP episodes from baseline (day 0) to 4 weeks postinjection. Values between the groups were compared with the Wilcoxon rank‐sum test.
Results
The intent‐to‐treat analysis included 46 BTA‐treated patients and 44 placebo recipients. At 4 weeks after assigned treatment injections, the median number of daily RP episodes decreased comparably in the BTA and placebo groups (median change –1 episode/day interquartile range (IQR) –1.5, 0 episodes/day and –1 episode/day IQR –2.5, 0 episodes/day, respectively) (P = 0.77 versus placebo). Moreover, change in Raynaud's Condition Score, quality of life assessed by Health Assessment Questionnaire disability index, and hand function assessed by shortened Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and Cochin Hand Function Scale from baseline to follow‐up weeks 4, 12, and 24 did not differ significantly between groups. The BTA group experienced transient hand muscle weakness significantly more frequently (P = 0.003).
Conclusion
Neither the primary nor secondary end points were reached, and our results do not support any beneficial effect of palmar BTA injections to treat SSc‐RP.

Psoriasis (Pso) and psoriatic arthritis (PsA) frequently have a negative impact on patients' sexual health. We have developed a specific questionnaire assessing the impact of Pso and PsA on patient ...perception of sexuality: the QualipsoSex Questionnaire (QSQ). The aim of the present study was to further validate this questionnaire by checking its psychometric properties including validity, reliability, and responsiveness.A cross sectional observational study with a longitudinal component for responsiveness and test-retest reliability was performed in 12 centers in France including 7 dermatologists and 5 rheumatologists. Psychometric properties were examined according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) check-list.At baseline, 114 patients had Pso and 35 patients had PsA including 17 peripheral arthritis, 4 axial disease, 13 patients with both axial disease and peripheral arthritis and one patient with an undifferentiated phenotype. The mean Pso Area and Severity Index score was 12.5. Genital organs were involved in 44.7% of Pso cases. Internal consistency, construct validity, and reliability were good with Cronbach's α coefficient, measure of sampling adequacy and intraclass correlation coefficient respectively at 0.87, 0.84, and 0.93. The QSQ also demonstrated acceptable sensitivity to change.The QSQ has demonstrated good psychometric properties fulfilling the validation process relative to the recommendations of the COSMIN check list. The QSQ is simple to score and may hopefully be valuable in clinical practice and in clinical trials.
Background
Some studies have shown that a high neutrophil/lymphocyte ratio (NLR) ≥4 before initiating ipilimumab treatment is an independent prognostic indicator of poor survival in patients with ...metastatic melanoma (MM).
Objectives
To determine whether the NLR before starting BRAF inhibitor (BRAFi) treatment in patients with (MM) is associated with progression-free survival (PFS).
Materials & methods
This retrospective study included 49 patients consecutively receiving BRAFi for MM between July 2012 and December 2014. Cox proportional hazards regression was used to analyse the relationship between NLR and other factors, such as lactate dehydrogenase (LDH), performance status, BRAFi as firstor second-line therapy, and corticosteroid intake with PFS. The NLR before starting BRAFi was significantly associated with PFS based on univariate analysis and multivariate analysis adjusted for potential confounding factors, such as LDH activity, ulceration, performance status, first-line therapy, and corticosteroid intake. A high NLR (continuous variable) was associated with short PFS (HR: 1.35; 95% CI: 1.07-1.70;
p
= 0.01), and NLR ≥4 was associated with shorter PFS (HR: 3.24; 95% CI: 1.30-8.12;
p
= 0.01). Corticosteroid intake was not associated with short PFS based on multivariate analysis.
Conclusion
An NLR > 4, before starting BRAFi treatment, is an independent prognostic indicator of poor progression-free survival.

Anti-interleukin-17 agents have recently been developed for the treatment of psoriasis. This study evaluated the tolerance and effectiveness of anti-interleukin-17 agents for psoriasis in elderly ...patients in daily practice. A multicentre, retrospective study was performed, involving psoriatic patients aged ≥65 years who had received an anti-interleukin-17 agent, including secukinumab, ixekizumab or brodalumab. A total of 114 patients were included: 72 received secukinumab, 35 ixekizumab, and 7 brodalumab. Treatment was stopped in 32 patients (28.9%), because of relapses in 14 patients (41.2%), primary failures in 11 patients (32.4%), or adverse events in 7 patients (20.6%). The 3 most frequently reported adverse events were injection site reactions (n = 4), oral candidiasis (n = 3), and influenza-like illness (n = 3). Regarding effectiveness, 80 patients (70%) reached a Physician Global Assessment score of 0/1, 6 months after treatment initiation. In conclusion, anti-interleukin-17 therapy appears to be an effective and safe therapeutic option for psoriasis treatment in patients aged ≥ 65 years.
