[Characteristics of melanoma in Mexicans seen at "La Raza" National Medical Center].

Background: Melanoma is the third most common type of skin cancer in Mexico and represents 75% of skin cancer deaths. Dermoscopy is a diagnostic tool that increases early detection of melanoma compared to naked eye examination.

Objective: The aim of this study was to describe the clinical, dermoscopic and histological characteristics of patients with a confirmed diagnosis of cutaneous melanoma treated at the "La Raza" National Medical Center.

Ancestry and somatic profile predict acral melanoma origin and prognosis.

Acral melanoma, which is not ultraviolet (UV)-associated, is the most common type of melanoma in several low- and middle-income countries including Mexico. Latin American samples are significantly underrepresented in global cancer genomics studies, which directly affects patients in these regions as it is known that cancer risk and incidence may be influenced by ancestry and environmental exposures. To address this, here we characterise the genome and transcriptome of 128 acral melanoma tumours from 96 Mexican patients, a population notable because of its genetic admixture.

Dermatoscopic Patterns in Vitiligo.

Vitiligo is a chronic, acquired autoimmune pigmentary skin disease, most times it can be diagnosed clinically. Dermoscopy can confirm vitiligo in a non-invasive way. It is a diagnostic technique that visualizes sub-macroscopic morphological structures which correspond with specific histological structures.

Reflectance Confocal Microscopy Terminology in Spanish: A Delphi Consensus Study.

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.

Dermatoscopic Patterns in Childhood Vitiligo and Their Association With Reflectance Confocal Microscopy Findings.

Introduction: The diagnosis of vitiligo is mainly based on clinical findings. However, dermoscopy or reflectance confocal microscopy (RCM) could be useful for assessing its progression (stability, pigmen-tation, or depigmentation).

Objectives: To evaluate the correlation of dermatological findings by dermoscopy and RCM in pediatric vitiligo.
