AI Article Synopsis
- - A study was conducted to analyze the occurrence and types of pigmented lesions in the oral mucosa within a Brazilian population over a 45-year period, finding that only 0.99% of diagnosed lesions were pigmented.
- - The study revealed that out of 761 pigmented lesions, 46.1% were melanocytic and 53.9% non-melanocytic, with a higher prevalence in females aged 40-70, and the most common lesions identified were amalgam tattoos and melanotic macules.
- - The results are consistent with previous research, underscoring the importance of understanding oral pigmented lesions to improve diagnostic capabilities and patient management in clinical practice.
Article Abstract
Background: Pigmented lesions are uncommon in the oral mucosa, and studies investigating the incidence and types of these lesions are desired to improve the diagnostic knowledge of clinicians. The aim of this study was to analyze the distribution of oral pigmented lesions in a Brazilian population.
Material And Methods: A retrospective descriptive cross-sectional study was performed. Oral pigmented lesions were retrieved from the files of two oral and maxillofacial pathology services from Brazil over a 45-year period (1974-2019). The clinical data and the diagnoses of each case were retrieved and included in a Microsoft Excel® database.
Results: From 77.074 lesions diagnosed in this period, 761 (0.99%) represented pigmented lesions of the oral mucosa, including 351 (46.1%) melanocytic and 410 (53.9%) non-melanocytic lesions, with a higher incidence in females (73.2%) between the fourth and seventh decades of life. Amalgam tattoo (53.6%) represented the most common lesion, followed by melanotic macule (18.3%) and racial pigmentation (10.8%). Other pigmented lesions included nevus (9.9%), post-inflammatory pigmentation (3%), melanoma (2.1%), melanoacanthoma (1.4%), smoker's melanosis (0.4%), drug-induced pigmentation (0.3%), and melanotic neuroectodermal tumor of infancy (0.1%). The buccal mucosa was the most commonly affected site (25.2%), followed by the alveolar ridge (14.5%), and gingiva (11.8%).
Conclusions: The current findings were similar to previous studies with minor differences due methodology and characteristics of the services from where lesions were retrieved. The knowledge of these data may contribute to a better understanding of oral pigmented lesions and assist clinicians to better recognize and manage them.

Focusing on the Dark Side of the Moon: Involvement of the Nonlesional Skin in Vitiligo.
J Invest Dermatol
December 2024
Immaculate Institute of Dermatopathology and Scientific Institute of Recovery, Hospitalisation and Cure (IDI-IRCCS), Rome, Italy.
Research over the last decade has revealed that the normally pigmented skin of patients with vitiligo is not normal at all, as evidenced by alterations in cutaneous morphology and modifications in cellular and metabolic functions that ultimately drive immune activation against melanocytes. Furthermore, nonlesional skin is in a state of subclinical inflammation until triggered by internal and/or external exposomal events. Therefore, targeting early processes that drive immune dysregulation in normally pigmented skin may avoid or reduce melanocyte loss.

Clinical characteristics and risk factors of bacillary layer detachment in central serous chorioretinopathy: a comparative multicenter study.
Int J Retina Vitreous
December 2024
Federal University of São Paulo, São Paulo, Brazil.
Background: Central serous chorioretinopathy (CSC) is marked by serous retinal detachments caused by fluid leakage from the retinal pigment epithelium, often associated with stress, psychiatric disorders and the use of corticosteroids. This study aims to investigate the clinical and systemic characteristics associated with BALAD in patients with CSC, comparing those with and without BALAD to clarify its function as a biomarker of CSC severity and improve diagnostic and treatment approaches.
Purpose: Compare the clinical characteristics, risk factors, and optical coherence tomography (OCT) findings in patients with Central Serous Chorioretinopathy (CSC) with and without Bacillary Layer Detachment (BALAD), and to identify the distinguishing features and associated conditions of CSC with BALAD.
Photoreceptor-RPE loss ratio and fundus autofluorescence patterns as predictive factors for lesion progression in geographic atrophy.

December 2024
Department of Ophthalmology, Landesklinikum Mistelbach-Gänserndorf, Mistelbach, Austria.
Purpose: To assess the impact of the ratio between photoreceptor (PR) loss and retinal pigment epithelium (RPE) loss on the progression of geographic atrophy (GA) and to explore correlations between abnormal fundus autofluorescence (FAF) patterns and the PR-RPE loss ratio.
Design: Single-centre, retrospective case series.
Methods: Multimodal images from 87 treatment-naïve patients with GA and a follow-up of 6-24 months were included.
