    Introduction: Melanoma of the lentigo maligna (LM) type is challenging. There is lack of consensus on the optimal diagnosis, treatment, and follow-up.

    Dermoscopy aids in melanoma detection; however, agreement on dermoscopic features, including those of high clinical relevance, remains poor. In this study, we attempted to evaluate agreement among experts on exemplar images not only for the presence of melanocytic-specific features but also for spatial localization. This was a cross-sectional, multicenter, observational study. Dermoscopy images exhibiting at least 1 of 31 melanocytic-specific features were submitted by 25 world experts as exemplars. Using a web-based platform that allows for image markup of specific contrast-defined regions (superpixels), 20 expert readers annotated 248 dermoscopic images in collections of 62 images. Each collection was reviewed by five independent readers. A total of 4,507 feature observations were performed. Good-to-excellent agreement was found for 14 of 31 features (45.2%), with eight achieving excellent agreement (Gwet's AC >0.75) and seven of them being melanomaspecific features. These features were peppering/granularity (0.91), shiny white streaks (0.89), typical pigment network (0.83), blotch irregular (0.82), negative network (0.81), irregular globules (0.78), dotted vessels (0.77), and blue-whitish veil (0.76). By utilizing an exemplar dataset, a good-to-excellent agreement was found for 14 features that have previously been shown useful in discriminating nevi from melanoma. All images are public (www.isic-archive.com) and can be used for education, scientific communication, and machine learning experiments.

    Lentigo maligna and lentigo maligna melanoma in patients younger than 50 years: a multicentre international clinical-dermoscopic study
    (2024) Longo, Caterina; Sticchi, Alberto; Curti, Alex; Kaleci, Shaniko; Moscarella, Elvira; Argenziano, Giuseppe; Thomas, Luc; Guitera, Pascale; Huang, Chen; Tiodorovic, Danica; Apalla, Zoe; Peris, Ketty; del Regno, Laura; Guida, Stefania; Lallas, Aimilios; Kittler, Harald; Pellacani, Giovanni; Navarrete-Dechent, Cristian
    Background Lentigo maligna/lentigo maligna melanoma (LM/LMM) is usually diagnosed in older patients, when lesions are larger. However, it is important to detect it at an earlier stage to minimize the area for surgical procedure.

    Use of game-based learning strategies for dermatology and dermoscopy education: a cross-sectional survey of members of the International Dermoscopy Society
    (2024) Donoso, Francisca; Peirano, Dominga; Aguero, Rosario; Longo, Caterina; Apalla, Zoe; Lallas, Aimilios; Jaimes, Natalia; Navarrete-Dechent, Cristian
    Background Dermoscopy is a valuable tool in the diagnosis of various skin conditions. It increases sensitivity and specificity in skin cancer diagnosis, as well as in infectious, inflammatory and hair diseases. However, mastering the intricacies of dermoscopy can be challenging. In this context, innovative educational methods are sought, including game-based learning (GBL) strategies. Objectives To describe current perceptions, knowledge and use of GBL strategies in dermoscopy education, and identify strengths and challenges to enhance their use. Methods A web-based cross-sectional survey with 25 questions was distributed to members of the International Dermoscopy Society between October 2022 and April 2023. Responses were collected and analysed using frequency analysis and graphical representation. Results In total, 801 responses were received. Of these, 46.6% of respondents were unfamiliar with gamification and serious games. Among those acquainted with these concepts, 56.3% reported using GBL strategies for education. Younger participants were more likely to use GBL strategies (P = 0.02). Participants familiar with GBL believed it enhanced medical education (78.5%) but should not entirely replace traditional teaching methods (96.0%). For dermoscopy education specifically, 22.1% of respondents had used GBL strategies, with Kahoot! (35.5%) and YOUdermoscopy (24.1%) being the most commonly used platforms. Respondents found gaming strategies to be fun (95.5%), motivating (91.0%) and valuable for e-learning (94.4%). Conclusions Results from this survey demonstrate a favourable perception of GBL strategies in dermatology education, including dermoscopy. While there are ongoing challenges in validation, GBL strategies are promising and valuable tools that can aid the learning and teaching experience. Addressing implementation barriers and validating existing games could optimize the impact of GBL on dermatology education.
