    (2024) Cabo, Horacio; Salerni, Gabriel; Sabban, Emilia Cohen; Garlatti, Agustin Bollea; Orendain, Nicole; Rodriguez-Saa, Sonia; Bakos, Renato Marchiori; Pozzobon, Flavia Carolina; Gonzalez, Virginia M.; Peralta, Rosario; Navarrete-Dechent, Cristian; Peirano, Dominga; Perez-Fernandez, Elia; Puig, Susana
    Introduction: Studies focused on dermoscopic aspects of pigmented Bowen disease (pBD) in Latin American population are scarce and limited to only case reports or small series. Objectives: To report dermoscopic findings in a large series of 147 pBD diagnosed in Ibero-Latin American population. Methods: We conducted a multicentric, retrospective study on 147 histologically proven pBD under the auspices of the Dermoscopy Chapter of the Ibero-Latin American College of Dermatology. Results: The study population consisted of 77 females (52%) and 70 males (48%) with a mean age of 68.6 years. 70.1% of patients had skin phototype 3, 15.6% to skin phototype 2, and 14.3% to skin phototype 4. On clinical examination, near 60% of pBD were flat, 70% presented with scales, and 90% were asymmetric. Under dermoscopy, structureless hypopigmented areas, dots brown and pink color were the most frequently observed. Regarding specific dermoscopic clues to pBD, the most prevalent were structureless hypopigmented areas, vessels arranged in linear fashion at the periphery, and pigmented lines or pigmented dots distributed in a linear fashion. Clustered, coiled, and dotted vessels were observed in 55.8%, 45.6%, and 45.6% of the cases, respectively. Conclusions: We report a large series of cases of pBD in Latin American patients, with most patients being skin phototype 3 and 4. Distinctively in our study, the pigmented structures and the clues derived from the presence of melanin were much more frequent than in previous reports in fair skin.

    Dermoscopy in Selected Latin American Countries: A Preliminary Look into Current Trends and Future Opportunities Among Dermatology Residency Programs
    (2023) Perez, Mariana; Williams, Natalie M.; Avila, Alejandra M.; Bakos, Renato; Bittencourt, Flavia; Carlos-Ortega, Blanca; Garzona, Laura; Larre-Borges, Alejandra; Naverrete-Dechent, Cristian; Pinos, Victor; Salerni, Gabriel; Shum-Tien, Jackie; Jaimes, Natalia
    Introduction: Skin cancer remains a global public health burden. Dermoscopy is a useful technique that aids in early detection and increases diagnostic accuracy with adequate training. However, dermoscopy is not uniformly taught to residents worldwide. Dermoscopy training in Latin American dermatology residency programs has not been explored. Objectives: To assess current dermoscopy training among dermatology residency programs in Latin America (eg training modalities, preferred/most effective modalities per residents, diseases/pathologies taught). Methods: Cross-sectional survey distributed via e-mail between March and May 2021. Chief residents from Argentina, Brazil, Colombia, Costa Rica, Chile, Ecuador, Guatemala, Mexico, Panama, and Uruguay were invited to participate. Results: 81 chief residents completed the questionnaire (81/126, 64.2%). Seventy-two percent of programs had an established dermoscopy curriculum, with dedicated hours of training varying greatly by program. Institutions commonly utilized sessions with "unknown" dermoscopy images and direct teaching by experts in the clinical setting as supplements to lectures, also described by residents as most effective. The most commonly taught methods included pattern analysis (74.1%), the two-step algorithm (61.7%), and the ABCD rule (59.3%). Almost all respondents reported desiring additional training during residency and believe that dermoscopy training should be a requirement to graduate from residency. Conclusions: This study highlights a preliminary look into current landscape in dermoscopy training among selected Latin American dermatology residency programs, demonstrating room for improvement and standardization in dermoscopic education and training. Our results serve as a baseline reference and provide valuable information to guide future educational initiatives incorporating successful teaching strategies (eg. spaced education/repetition, flipped classroom model) used in dermatology and other fields.
