Abstract
BACKGROUND Oral lesions of immune-mediated and autoimmune diseases have been well-documented, but studies from Brazil are limited. The varied spectrum of oral lesions within this demographic group poses challenges to clinicians, particularly when they occur in isolation. This study aimed to evaluate the occurrence, clinical characteristics, and management of patients with oral lesions of immune-mediated and autoimmune diseases at a single center in Brazil. METHODS A retrospective cross-sectional study was conducted from 2010 to 2022. Clinicodemographic data, histopathological features, and treatment modalities were analyzed descriptively and analytically. RESULTS Of the 3,790 oral and maxillofacial lesions diagnosed, 160 (4.2%) were confirmed as immune-mediated or autoimmune diseases. The population surveyed predominantly consisted of women (73.7%), with a mean age of 60.2 years. Oral lichen planus (51.3%), mucous membrane pemphigoid (MMP) (23.7%), and pemphigus vulgaris (PV) (19.4%) were the most prevalent lesions. The buccal mucosa (59.4%) was predominantly affected, with pain reported in 46.2% of cases, notably in individuals with PV and MMP. The average time to disease stabilization post-local and/or systemic corticosteroid therapy was 15.8 months for systemic lupus erythematosus, 8.7 months for MMP, and 6.5 months for PV. CONCLUSION Although oral lesions related to immune-mediated and autoimmune diseases are uncommon, their diverse clinicopathological aspects require multidisciplinary management.

Reis CSM, Reis JGC, Conceição-Silva F, Valete CM. Oral and oropharyngeal mucosal lesions: clinical-epidemiological study of patients attended at a reference center for infectious diseases. Braz J Otorhinolaryngol 2024; 90:101396. [PMID: 38359743 PMCID: PMC10877199 DOI: 10.1016/j.bjorl.2024.101396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 12/05/2023] [Accepted: 12/26/2023] [Indexed: 02/17/2024] Open
Abstract
OBJECTIVE To determine the prevalence, epidemiological profile, and clinical characteristics of Oral or Oropharyngeal Mucosal Lesions (OOPML) in patients attended at the Otorhinolaryngology Service of the Evandro Chagas National Institute of Infectious Diseases (INI-FIOCRUZ) from 2005 to 2017. METHODS Statistical analysis of descriptive data from medical records (gender, age, education level, skin color, origin, smoking, alcoholism, HIV co-infection, time of disease evolution, first symptom, and OOPML location) was performed. RESULTS Of 7551 patients attended at the service, 620 (8.2%) were included in the study. OOPML were classified into developmental anomalies (n = 3), infectious diseases (non-granulomatous n = 220; granulomatous n = 155), autoimmune diseases (n = 24), neoplasms (benign n = 13; malignant, n = 103), and unclassified epithelial/soft tissue diseases (n = 102). OOPML of infectious diseases (60.5%) and neoplasms (18.7%) were the most frequent. The predominant demographics of patients with OOPML were: males (63.5%), white (53.5%), and those in the fifth to sixth decades of life (43.3%). Local pain (18.1%) and odynophagia (15%) were the most reported first symptoms, and the most frequent OOPML sites were the palatine tonsil (28.5%), hard palate (22.7%), and tongue (20.3%). The median evolution time was three months. CONCLUSIONS Infectious OOPML were the most frequent, as expected in a reference center for infectious diseases, and thus, they are likely to be less frequent in general care and/or dental services. Underreporting of OOPML is possible, as oral/oropharyngeal examination is often not included in the routine medical examination. Oral cavity/oropharynx examination should be performed by specialists, such as dentists and otorhinolaryngologists, who have the expertise in identifying OOPML, even in incipient/asymptomatic cases. Given the numerous diseases in which OOPML can present, diagnosis could be facilitated by multidisciplinary teams, potentially enabling the early treatment of diseases, and thus, reduce morbidity and improve prognosis. The use of standardized medical records for oral/oropharyngeal systematic examination could provide relevant tools for differential diagnoses and information for new clinical-epidemiological studies. LEVEL OF EVIDENCE Level 3.

Head Neck Pathol 2022; 16:969-979. [PMID: 35579856 PMCID: PMC9729480 DOI: 10.1007/s12105-022-01442-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Accepted: 02/24/2022] [Indexed: 12/24/2022]
Abstract
Histomorphometry seems to provide more rigid quantitative elements for histological analysis and to bring less subjectivity to the diagnosis of oral lichen planus lesions (OLP). This study aimed to verify the association between white and red lesions and histomorphometric characteristics of OLP lesions. This retrospective cross-sectional study assessed 48 hematoxylin- and eosin-stained histological sections from incisional biopsies obtained from OLP cases. A single previously calibrated evaluator performed the light microscopy analyses to evaluate morphological and morphometric parameters. Analyses of associations among variables were performed using the Fisher's exact test. Morphometric variables were assessed using the Mann-Whitney non-parametric test. Comparisons among the three groups (age range) were performed using the Kruskal-Wallis test. In this study, 81.2% of the participants were women aged < 50 years. Keratosis, acanthosis, and inflammatory infiltrates were noted in 10.4, 10.4, and 37.5% of moderate/severe cases, respectively. Inflammatory infiltrate (52.1%), papillary projections (54.2%), saw teeth (12.5%), basal layer degeneration (39.6%), and Civatte bodies (68.8%) were also observed. There was no significant association between lesion type and clinicopathological variables (p > 0.05) or between lesion type and histological (p > 0.05) and morphometric variables (p > 0.05). Furthermore, the morphometric variables analyzed did not differ between white and red lesions (p > 0.05) or in their associations with clinicopathological variables (p > 0.05). The results of this investigation showed no associations between white and red OLP lesions and the histomorphometric characteristics evaluated.

Abstract
AIM To provide an epidemiological characterization of ocular cicatricial pemphigoid (OCP) in Colombia. METHODS We conducted a cross-sectional study using SISPRO. We applied the specific code of the International Classification of Diseases for Ocular Pemphigoid, from 2009-2019 to estimate prevalence, incidence, and the demographic status of the disease in Colombia. RESULTS The estimated average prevalence was 0.22 per 1 000 000 inhabitants, and the estimated average incidence was 0.24 per 1 000 000 inhabitants. With a female predominance of 62.5%, and a male/female ratio of 1:1.6. The group of patients diagnosed with the disease after the age of 80 presented the highest prevalence. The departments with the highest prevalence were Antioquia, Bogotá, and Santander. CONCLUSION There are important differences between worldwide and Colombian prevalence and incidence data, which may be related to genetic and epigenetic factors, and the possible underdiagnosis of the disease. According to the results, OCP is an extremely rare disease in Colombia. Nevertheless, it is important to encourage awareness of the disease due to its devastating consequences.

Abstract
Introduction Oral lichen planus (OLP) is a chronic mucocutaneous disease. It is mainly an immune system-related disorder. Vitamins can modulate immune system functions, and thus, vitamin deficiency might have roles in exacerbating OLP. We aim to determine the serum levels of vitamins A, B12, C, D3, and E in OLP patients. Methods and Materials 34 OLP patients referred to Shiraz Dental School entered the study. Blood samples were collected and levels of A, B12, C, D3, and E vitamins were measured in serum. 43 healthy people were also included as the control group. Serum levels of vitamins were measured by HPLC (A, B12, D3, and E) and Kiazist analyzing kit (vitamin C). Results Most of the patients were female (62.3%), and the mean age of patients was 48.03 ± 11.57. Serum levels of vitamins A, C, and E were lower in OLP patients in comparison with the healthy group; however, the difference was not significant. Vitamins B12 and D3 were higher in the OLP group but the difference was not significant. Conclusion Serum levels of vitamins A, B12, C, D3, and E do not have a significant difference in OLP patients and healthy groups. These vitamins may not have a considerable role in OLP pathogenesis in the southwest of Iran.

Abstract
Objectives We sought to determine the prevalence of immune-mediated skin disorders (IMDs), their oral manifestations, and the related comorbidity among Omani patients with IMDs attending the outpatient Department of Dermatology and Dental Clinic at Al Nahdha Hospital, Muscat. Methods We conducted a retrospective study of 236 newly-diagnosed patients with IMDs who attended the outpatient clinic between September 2014 and September 2017. Data, such as age, sex, investigations, diagnosis, comorbidity, and associated oral manifestations of the affected individuals, were collected from the hospital health information system. Results Of the 236 diagnosed cases of IMD, lichen planus substantially comprised over half of the total cases (59.7%). This was followed by relatively fewer cases of discoid lupus erythematosus (11.0%), systemic lupus erythematosus (10.2%), and erythema multiforme (8.1%). Pemphigus vulgaris and bullous pemphigus comprised only 3.0% and 4.2% of the total studied cases, respectively. The other less common disorders found in our study were toxic epidermal necrolysis (1.7%), pemphigus foliaceus (1.3%), and gestational pemphigoid (0.8%). Oral mucosal involvement was seen more commonly with lichen planus (78.7%), pemphigus vulgaris (71.4%), and erythema multiforme (75.0%), while systemic lupus erythematosus and discoid lupus erythematosus were shown to appear with more comorbidities compared to the other skin disorders studied. Conclusions Several IMDs have considerable oral involvement. These oral manifestations of the diseases may be overlooked by other specialists leading to a delay in the diagnosis and its management. In order to circumvent this delay, the analysis and evaluation of a disease need to be done by a team comprising of a dental surgeon, dermatologist, and an oral medicine specialist.

Abstract
A group of autoimmune diseases is characterised by autoantibodies against epithelial adhesion structures and/or tissue-tropic lymphocytes driving inflammatory processes resulting in specific pathology at the mucosal surfaces and the skin. The most frequent site of mucosal involvement in autoimmune diseases is the oral cavity. Broadly, these diseases include conditions affecting the cell-cell adhesion causing intra-epithelial blistering and those where autoantibodies or infiltration lymphocytes cause a loss of cell-matrix adhesion or interface inflammation. Clinically, patients present with blistering, erosions and ulcers that may affect the skin as well as further mucosal surfaces of the eyes, nose and genitalia. While the autoimmune disease may be suspected based on clinical manifestations, demonstration of tissue-bound and circulating autoantibodies, or lymphocytic infiltrates, by various methods including histological examination, direct and indirect immunofluorescence microscopy, immunoblotting and quantitative immunoassay is a prerequisite for definitive diagnosis. Given the frequency of oral involvement and the fact that oral mucosa is the initially affected site in many cases, the informed practitioner should be well acquainted with diagnostic and therapeutic aspects of autoimmune dermatosis with oral involvement. This paper reviews the pathogenesis and clinical presentation of these conditions in the oral cavity with a specific emphasis on their differential diagnosis and current management approaches.

Abstract
AIM The aim of the present study was to analyze data on the characteristics of tongue lesions in dental patients seeking care at the Oral Pathology Service of Tehran University of Medical Sciences, from 1985-2010. MATERIALS AND METHODS Demographic data and histopathologic diagnoses were recorded for all lesions that were documented as occurring on the tongue according to the patient records in our department. Statistical analysis included chi-square, t-, and Fisher's exact tests. A 95% confidence interval (CI) was calculated, and p < 0.05 was considered significant. RESULTS Tongue lesions constituted 6.3% of all received specimens which included 46 different defects. The most common lesions were lichen planus (LP), irritation fibroma (IF), squamous cell carcinoma (SCC) and pemphigus vulgaris (PV). Tongue lesions were significantly more common in women compared to men (CI = 0.65-0.94, p = 0.02). Mean age (47 years) did not differ between male and female subjects (CI = -2.49 - 3.93, p = 0.06). The dorsal surface followed by the lateral aspect was the most common site for tongue lesions. CONCLUSION It seems that dental practitioners should be perceptive of LP, IF, SCC and PV, when examining the tongue. Histopathologic analysis is essential for achieving final diagnosis in a considerable number of lesions that commonly occur on this organ. Clinical significance: Access to demographic/prevalence data in different populations may be useful in clinical settings and could be complimented by histopathologic diagnosis in most instances. The present findings can be compared with those obtained from other epidemiologic studies in this field resulting in valuable data which may be used in several types of investigations. .

Abstract
AIM Aim of the study is to study the surface epithelial cells of erosive, nonerosive lichen planus by scanning electron microscope (SEM) and to correlate it with that of normal mucosa and oral leukoplakia. MATERIALS AND METHODS Twenty biopsies of lichen planus and five biopsies of normal mucosa were taken. Half piece of each biopsy was processed for H&E stain and another half for SEM study. RESULT Surface epithelial cells were showing different features. CONCLUSION Definite different features were seen in lichen planus-leukoplakia group than in normal oral mucosa. These changes are due to abnormality in cell maturation and differentiation. CLINICAL SIGNIFICANCE SEM study is helpful in early detection of dysplasia. It can lead to early treatment of the lesion and thus prevention of squamous cell carcinoma.
