Extramammary Paget disease (EMPD) is a rare skin tumor that manifests as poorly delimited lesions located mainly in genital area. Prognosis correlates with thickness and dermal invasion. The gold standard for diagnosis is the histopathological study of a biopsy. However, this technique is invasive and only shows a small area of the tumor. A good correlation has been reported between ultrasounds (US) and histopathologic finding. Moreover, a US examination has the advantages of wide availability, noninvasiveness, low cost, ease of use, and real‐time scanning. We review the ultrasound signs described for this disease.

Background: Moderate-to-severe atopic dermatitis (AD) can be difficult to manage in paediatric patients, with few licensed treatments in this age group. Dupilumab is approved for AD in children older than 6 months., Objectives: To assess the effectiveness and safety of dupilumab in a real-life cohort of paediatric AD patients in Spain., Methods: A multicentre, retrospective real-life study on the effectiveness and safety of dupilumab in patients aged 2 to 18 years old with moderate-to-severe AD was conducted. Demographic and clinical characteristics were analysed, and effectiveness (EASI, IGA, DLQI, NRS itch), safety, and drug survival measures were assessed. A comparison of our results with other real-world outcomes and with clinical trials was made., Results: Data from 243 patients from 19 centres was collected, with a mean follow-up of 85 weeks. Dupilumab exhibited significant effectiveness, with marked reductions in severity scores from week 4. By week 16, 79.4% of patients reached EASI75 and 40.5% reached EASI90. Mean percentage reduction in EASI was 79.7%. Increasing improvements were observed until week 52, with 85.8% and 49.6% achieving EASI75 and EASI90, respectively. Forty-three patients developed adverse events (AE) (43/243, 17.7%), being the most frequent ocular surface diseases (20/243, 8.2%), injection site reactions (8/243, 3.3%) and facial redness (7/243, 2.9%). Drug survival was high (96.9% and 93.1% after 1 and 2 years of follow-up, respectively), with only 19 (19/243, 7.8%) patients interrupting treatment: 7 (7/243, 2.9%) due to AE, 2 (2/243, 0.82%) due to secondary failure, 5 (5/243, 2.1%) were lost to follow-up and 5 (5/243, 2.1%) entered remission and stopped treatment., Conclusion: Real-life use of dupilumab in paediatric AD showcased sustained effectiveness, high drug survival, and acceptable safety profiles. Longer-term studies are crucial for AE surveillance and how to manage disease remission., (© The Author(s) 2024.
