    Consenso de terminología en microscopia confocal de reflectancia en español mediante método Delphi
    (2023) Abarzúa, Alvaro; Banuls, J.; Cabo, H.; Carrera, C.; Gamo, R.; González, S.; Jaimes, N.; Navarrete Dechent, Cristián Patricio; Perez Anker J.; Roldan Marín, R.; Segura, S.; Yelamos, O.; Puig, S.; Malvehy, J.
    La terminología usada para describir los diferentes hallazgos en la microscopía confocal de reflectancia (MCR), tanto en lesiones melanocíticas, como en no melanocíticas se ha consensuado en inglés. En el presente trabajo, se proponen los términos en español que mejor interpretan estos conceptos ya descritos para la MCR, mediante el consenso de expertos de distintas nacionalidades de habla hispana y utilizando el método DELPHI para el acuerdo final. Se obtuvieron 52 términos en total, de los cuales 28 fueron para lesiones melanocíticas y 24 para lesiones no melanocíticas. El uso de la nomenclatura propuesta permitirá una homogeneización y mejor entendimiento de las estructuras; una descripción más estandarizada en los registros clínicos y una mejor interpretación de estos informes por otros dermatólogos.

    Dermoscopy of porokeratosis: results from a multicentre study of the International Dermoscopy Society
    (2021) Zaar, O.; Polesie, S.; Navarrete-Dechent, C.; Errichetti, E.; Akay, B. N.; Jaimes, J.; Cabo, H.; Sabban, E. Cohen; Paoli, J.
    Background The diagnosis of porokeratosis can be challenging, and knowledge about its dermoscopic features is limited. Objectives To describe the dermoscopic features of porokeratosis of Mibelli and disseminated superficial actinic porokeratosis (DSAP) and the frequency of these features in a larger case series. The interobserver concordance was also assessed. Methods In this retrospective cohort study, members of the International Dermoscopy Society contributed macroscopic and dermoscopic images of histopathologically verified cases of porokeratosis of Mibelli or DSAP. Three observers independently reviewed the collected images to identify the presence of predefined dermoscopic features. Following this, a consensus meeting was held to agree upon which dermoscopic features were present in each lesion. Results In total, 78 clinical and dermoscopic images of porokeratoses were collected. The most common dermoscopic feature was keratin rim, which was present in 74 lesions (92.3%). The most common vascular structures were dotted or glomerular vessels which were present in almost half of the cases (48.7%). Other relatively frequent dermoscopic findings were as follows: non-peripheral scales (44.9%), grey-brown dots or pigmentation along the keratin rim (38.5%), and light-brown pigmentation within the keratin rim (33.3%). Shiny white structures and blood spots or erosions along the keratin rim were findings never before described in porokeratosis and were detected in 16.7% and 17.9% of the lesions, respectively. Dermoscopic findings in porokeratosis of Mibelli and DSAP were similar except for fewer blood spots or erosions along the keratin rim and more light-brown pigmentation within the keratin rim in DSAP. The interobserver concordance ranged from 0.44 (moderate) to 0.84 (almost perfect). Conclusions The dermoscopic hallmark of porokeratosis is the keratin rim, a finding also allowing for almost perfect interobserver agreement. Pigmentation or erosions along the keratin rim, vascular structures, as well as scales, pigmentation or shiny white structures within the keratin rim are additional dermoscopic clues.

    Reflectance Confocal Microscopy Terminology in Spanish: A Delphi Consensus Study
    (2024) Abarzua-Araya, A.; Banuls, J.; Cabo, H.; Carrera, C.; Gamo, R.; Gonzalez, S.; Jaimes, N.; Navarrete-Dechent, C.; Anker, J. Perez; Roldan-Marin, R.; Segura, S.; Yelamos, O.; Puig, S.; Malvehy, J.
    The terminology used to describe reflectance confocal microscopy (RCM) findings in both melanocytic and nonmelanocytic lesions has been standardized in English. We convened a panel of Spanish-speaking RCM experts and used the Delphi method to seek consensus on which Spanish terms best describe RCM findings in this setting. The experts agreed on 52 terms: 28 for melanocytic lesions and 24 for nonmelanocytic lesions. The resulting terminology will facilitate homogenization, leading to a better understanding of structures, more standardized descriptions in clinical registries, and easier interpretation of clinical reports exchanged between dermatologists.
