BCN20000: Dermoscopic Lesions in the Wild

Carlos Hernández-Pérez, Marc Combalia, Sebastián Podlipnik, Noel Codella et autres

Advancements in dermatological artificial intelligence research require high-quality and comprehensive datasets that mirror real-world clinical scenarios. We introduce a collection of 18,946 dermoscopic images spanning from 2010 to 2016, collated at the Hospital Clínic in Barcelona, Spain. The BCN20000 dataset aims to …

Concordance of in vivo reflectance confocal microscopy and horizontal‐sectioning histology in skin tumours

Francesca Perino, Raúl Alcántara-Suárez, Javiera Pérez‐Ánker, Cristina Carrera et autres

BACKGROUND: In vivo reflectance confocal microscopy (RCM) enables the study of architectural and cytological aspects in horizontal sections, which closely correlate with histologic features. However, traditional histopathological vertical sections cannot totally reproduce the image of the in vivo RCM horizontal section. OBJECTIVE: …

Reflectance Confocal Microscopy and Electrical Impedance Spectroscopy in the Early Detection of Melanoma in Changing Lesions during Long-term Follow-up of Very High-risk Patients

Marion Chavez-Bourgeois, Simone Ribero, Alicia Barreiro, Natalia Espinoza et autres

Electrical impedance spectroscopy has clinical relevance in diagnosing malignancy in melanocytic lesions. Sixty-eight lesions with changes during digital follow-up of patients at very high risk of developing melanoma were prospectively included in this study from February to December 2016. Electrical impedance spectroscopy …

Clinicopathological, Genetic and Survival Advantages of Naevus-associated Melanomas: A Cohort Study

Xavier Bosch‐Amate, Sebastián Podlipnik, Constanza Riquelme‐Mc Loughlin, Cristina Carrera et autres

Several studies have suggested that naevus-associated melanomas differ from de novo melanomas, being thinner and with less ulceration; however, the prognostic implication is unclear. The objective of this study was to describe clinicopathological, genetic and survival characteristics of de novo and naevus-associated …

Initial Stage of Cutaneous Primary Melanoma Plays a Key Role in the Pattern and Timing of Disease Recurrence

Sümeyre Seda Ertekin, Sebastián Podlipnik, Constanza Riquelme‐Mc Loughlin, Alicia Barreiro et autres

Given recent developments in the treatment of metastatic melanoma, early detection of disease recurrence is crucial. The aim of this single-centre retrospective cohort study was to investigate the impact of the initial stage of primary melanoma on the pattern and timing of …

Influence of germline genetic variants on dermoscopic features of melanoma

Flavia Carolina Pozzobon, Gemma Tell‐Martí, Neus Calbet‐Llopart, Alicia Barreiro et autres

Nevus count is highly determined by inherited variants and has been associated with the origin of melanoma. De novo melanomas (DNMMs) are more prevalent in patients with a low nevus count and have distinctive dermoscopic features than nevus-associated melanomas. We evaluated the …

Melanocortin‐1 receptor ( MC1R ) genotypes do not correlate with size in two cohorts of medium‐to‐giant congenital melanocytic nevi

Neus Calbet‐Llopart, Mirella Pascini‐Garrigos, Gemma Tell‐Martí, Míriam Potrony et autres

Congenital melanocytic nevi (CMN) are cutaneous malformations whose prevalence is inversely correlated with projected adult size. CMN are caused by somatic mutations, but epidemiological studies suggest that germline genetic factors may influence CMN development. In CMN patients from the U.K., genetic variants …
