RESUMO
BACKGROUND: Systemic lupus erythematosus (SLE) is a multifactorial autoimmune disease that may affect the oral mucosa. The variable spectrum of oral lesions observed in SLE can pose challenges in diagnosis, particularly when the lesions occur in isolation. The aim of this study was to describe the oral lesions occurring in patients with SLE from Latin America. METHODS: This collaborative record-based study involving 11 oral and maxillofacial pathology and medicine services across Venezuela, Argentina, Chile, Brazil, and Mexico describes the clinicopathological profile of SLE-related oral lesions. RESULTS: Seventy patients with SLE and oral lesions were included in the study. The majority were females (75.7%; female/male ratio: 3.1:1) and white (62.1%), with a mean age of 38.4 years (range: 11-77 years). The most common site of oral lesions was the hard/soft palate (32.0%). Clinically, oral lesions predominantly presented as ulcers (26.6%), erosions (26.6%), and white lesions (23.4%). Isolated oral lesions occurred in 65.2% of individuals, while cutaneous manifestations occurred in 80.3%. The main clinical diagnostic hypothesis in 71.4% of cases was an immune-mediated disease. Oral biopsies followed by histopathological analysis were performed in 50 cases. CONCLUSION: Oral lesions of SLE exhibit a variety of clinical and histopathological features. A key point in diagnosis is that unusual oral changes without an obvious local cause may indicate a possible systemic condition presenting with oral lesions. A multidisciplinary approach, which includes regular oral examination, is warranted to identify oral lesions and provide treatment.

OBJECTIVE: This study aimed to explore perceived barriers to early diagnosis and management of oral cancer, as well as potential pathways for improvement in Latin America and the Caribbean (LAC). METHODS: This cross-sectional study used a self-administered online questionnaire created via the Research Electronic Data Capture platform. The survey was distributed to health professionals trained in Oral Medicine, Oral Pathology, Oral and Maxillofacial Surgery, and Dentists with clinical and academic expertise in oral potentially malignant disorder (OPMD) and oral cancer. Data obtained were systematically organized and analyzed descriptively using Microsoft Excel. RESULTS: Twenty-three professionals from 21 LAC countries participated. Major barriers included the limited implementation of OPMD and oral cancer control plans (17.4%), low compulsory reporting for OPMD (8.7%) and oral cancer (34.8%), unclear referral pathways for OPMD (34.8%) and oral cancer (43.5%), and a shortage of trained professionals (8.7%). Participants endorsed the utility of online education (100%) and telemedicine (91.3%). CONCLUSION: The survey highlights major perceived barriers to early diagnosis and management of OPMD and oral cancer in LAC, as well as potential avenues for improvement.
RESUMO
OBJECTIVE: To determine the frequency of oral squamous cell carcinoma (OSCC) associated or not with oral potentially malignant disorders (OPMD), and the epidemiological profile and traditional risk factors in Latin America. METHODS: A retrospective observational study was conducted in 17 Latin American centres. There were included cases of OSCC, analysing age, gender, OSCC and their association with previous OPMD. Clinicopathological variables were retrieved. The condition of sequential-OSCC versus OSCC-de novo (OSCC-dn) was analysed concerning the aforementioned variables. Quantitative variables were analysed using Student's t-test, and qualitative variables with chi-square. RESULTS: In total, 2705 OSCC were included with a mean age of 62.8 years old. 55.8% were men. 53.75% of the patients were smokers and 38% were common drinkers. The lateral tongue border was the most affected site (24.65%). There were regional variations in OPMD, being leukoplakia the most frequent. Of the overall 2705 OSCC cases, 81.4% corresponded to OSCC-dn, while s-OSCC were 18.6%. Regarding lip vermillion SCC, 35.7% corresponded to de novo lip SCC and 64.3% were associated with previous OPMD. CONCLUSIONS: In Latin America, OSCC-dn seems to be more frequent with regional variations of some clinical and histopathological features. Further prospective studies are needed to analyse this phenomenon.
RESUMO
BACKGROUND: A proportion of oral squamous cell carcinoma (OSCC) is preceded by oral potentially malignant disorders (OPMD), and the rest might not be associated with any well-established OPMD. Chronic traumatic ulcer (CTU) has been suggested as a lesion with potential for malignant transformation, but the evidence is inconclusive. OBJECTIVE: The aim of this study was to describe clinicopathological features of non-healing CTU (NHCTU) that later developed to OSCC. MATERIALS AND METHODS: A retrospective cohort study was performed of patients attending the Facultad de Odontología Universidad Nacional de Córdoba (2013-2019). The study included patients with a provisional diagnosis of CTU. CTUs without complete healing after removal of traumatic factors-non healing CTU (NHCTU)-were investigated by biopsy. A detailed description of cases where a malignancy was diagnosed is presented. RESULTS: A total of 107 CTU were included. Of these, 32 CTUs were considered NHCTU and two cases showed histological features of OSCC in the background of NHCTU. In both cases, lesions were found on the lateral tongue. Both were non smoking, non alcohol drinking individuals. Absence of any well-known OPMD was also registered. CONCLUSIONS: The possibility of malignant transformation in a subset of tongue NHCTU should not be underestimated. CLINICAL RELEVANCE: In a subgroup of patients, NHCTU could be considered an OPMD. Although the potential malignant transformation rate is low, these conditions should be always followed up.

OBJECTIVE: To report the clinicopathologic features of acquired oral syphilis cases in South American countries. MATERIALS AND METHODS: Clinical data were retrospectively collected from the records of 18 oral diagnostic services in Argentina, Brazil, Chile, Colombia, Venezuela, Uruguay, and Peru. Serologies of nontreponemal and treponemal tests were used for diagnosis. RESULTS: The series comprised 339 cases of acquired oral syphilis. Secondary syphilis ranked as the most common stage (86.7%). Lesions were more frequent among males (58.0%) and young adults with a mean age of 33.3 years. Individuals aged 20-29 years were most affected (35.3%). The most commonly involved sites were the tongue (31.6%), lip/labial commissure (25.1%), and hard/soft palate (20.4%). Clinically, acquired oral syphilis usually presented as mucous patches (28.4%), papules (25.7%), and ulcers (18.1%). Skin manifestations occurred in 67.7% of individuals, while lymphadenopathy and fever were observed in 61.3% and 11.6% of all subjects, respectively. Most patients were treated with the benzathine penicillin G antibiotic. CONCLUSION: This report validates the spread of acquired oral syphilis infection among young adults in South America. Our directives include accessible diagnostic tools for proper disease screening, surveillance, and counselling of affected individuals, especially in low- and middle-income countries.

OBJECTIVES: Oral squamous cell carcinoma (OSCC) is a multifactorial disease. The individual effect of each risk factor for OSCC may be conditioned by the frequency of other factors. The objective of this study was to identify the association between chronic mechanical irritation (CMI) and OSCC and to analyse the influence of CMI on other important risk factors for OSCC. MATERIALS AND METHODS: A prospective and age/sex-matched case-control study was performed in two institutions from Argentina between 2009 and 2019, with consecutive and newly diagnosed OSCC. The frequencies of tobacco, alcohol, and CMI were analysed using conditional logistic regression. Cumulative tobacco consumption and the presence of CMI were analysed using the Mann-Whitney test. RESULTS: CMI and OSCC were associated with an OR of 7.02 (95% CI 3.57-13.78, p < 0.001). The combination of CMI and alcohol demonstrated the highest risk of OSCC (OR 53.83, CI 95% 8.04-360, p < 0.0001), followed by the combination of CMI, tobacco, and alcohol (OR 48.06, CI 95% 8.47-272, p < 0.0001). The combination of CMI and tobacco was also significant (OR 5.61, CI 95% 1.07-29.54, p = 0.042). Patients with CMI developed OSCC with less cumulative tobacco use compared with those without CMI. CONCLUSION: CMI is an independent risk factor for OSCC, and it could act as a risk modifier among tobacco and alcohol users having an enhancing effect. CLINICAL RELEVANCE: Elimination of CMI could decrease the risk of OSCC.

BACKGROUND: Multiple white plaques of the oral mucosa are usually associated with potentially malignant disorders such as oral lichen planus, oral lichenoid lesions and proliferative verrucous leukoplakia. Previous studies in the current literature describe a potential clinical overlap in these entities. The aim of this study is to review clinicopathological and evolutive features of these Oral Potentially Malignant Disorders highlighting the dynamic changes of diagnoses. DISCUSSION: It was previously hypothesized that a subset of patients with oral lichen planus or oral lichenoid diagnosis, could develop multiple white plaques during the natural history of the disease, fulfilling diagnostic criteria for proliferative verrucous leukoplakia. Consequently, these entities could, under certain conditions, obey a continuum of the same precancerous condition in the context of the field cancerization theory, increasing the risk of malignant transformation. Nevertheless, there is limited scientific evidence concerning this issue. CONCLUSION: Further studies are needed to understand the biological and evolutive features of the link between these oral potentially malignant disorders. Regardless of its diagnosis, these patients with multifocal white lesions must be carefully monitored to detect early malignant transformation.

BACKGROUND: Calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia (CREST) syndrome is an acronym for the clinical features that are seen. Its etiology is unknown, affecting women three times more than men. CREST syndrome is often diagnosed by systemic symptoms. However, oral manifestations could be helpful in the early diagnosis of the disease. Less than 20 cases of CREST syndrome with oral symptoms were described. OBJECTIVE: To report a case of a 26-year-old female, who was diagnosed with CREST syndrome based on findings of the oral mucosa. CASE REPORT: Clinical examination revealed sclerodactyly and nail alterations. Oral findings were associated with hypochromic and paleness mucosa. The tongue was strongly rigid and reddish areas compatible with telangiectasias were found. The mouth opening was particularly compromised. Histological findings were suggestive of systemic sclerosis in the context of CREST syndrome. Considering the available diagnosis criteria, this case was diagnosed as CREST syndrome based on oral manifestations. CONCLUSIONS: Oral manifestations of CREST syndrome could help in early clinical diagnosis, preventing a delay in the onset of an aggressive form of the disease. Accurate referrals of patients to specialists are needed for a multidisciplinary approach.
RESUMO
OBJECTIVE: Previous isolated reports have hypothesized that chewing coca leaves, a pre-Columbian tradition found in certain regions of South America, may be associated with the development of oral squamous cell carcinoma (OSCC). Coca chewing (CC) is a habit that shares many characteristics with the well-known practice of betel chewing observed in Asia. The aim of this study is to analyze the association between CC and OSCC among patients who attended the Señor del Milagro Hospital in Salta, Argentina. STUDY DESIGN: A case-control study was conducted from 2013 to 2018. For each case of OSCC, three healthy control patients were included. Odds ratios were calculated to compare demographics, concurrent oral conditions, and other classical risk factors for OSCC. RESULTS: A total of 62 cases and 180 controls were included, adjusted for sex and age. OSCC was significantly associated with tobacco use (27.4% vs 9.4%, P = .001), CC (62.9% vs 32.2%, P < .001), and poor oral condition (81.1% vs 67.7%, P = .02). In the multivariate analysis, smoking (OR = 2.77, 95% CI 1.23-6.25, P = .0139), CC (OR = 2.98, 95% CI 1.58-5.63, P = .0007), and poor oral condition (OR = 3.1, 95% CI 1.62-5.85, P = .0006) remained independently associated with OSCC development. CONCLUSIONS: Chewing coca leaves could be considered a risk factor for oral cancer in a subset of Argentinean patients. Further studies are necessary to validate our findings and to elucidate the underlying pathways linking this habit to oral carcinogenesis.

Phleboliths are reported as calcifications that occur in vascular malformations, associated with changes in blood flow dynamics, thrombus formation and subsequent calcifications. Radiological examination, such as cone beam computed tomography (CBCT) could help in demonstrating the presence of a calcifiied mass. A 45-year-old male was referred to our service with an asymptomatic nodular purplish lesion located on the ventrolateral tongue. Within the lesion, a stony mass was also evident on palpation. A digital dental radiograph demonstrated two circumscribed radiopaque structures. Phleboliths associated with vascular malformation was the main diagnostic hypothesis. The patient underwent a sclerotherapy protocol allowing surgical accessibility to the area. Phlebolyts were surgically removed using electrocoagulation. Histopathological examination revealed phleboliths in the context of a vascular malformation with intense fibrosis.

OBJECTIVE: To analyze the frequency of sequential oral squamous cell carcinomas (s-OSCC), preceded by oral potentially malignant disorders, and OSCC de novo (OSCC-dn) and explore differences in their clinicopathologic presentations. STUDY DESIGN: A structured electronic search strategy identified studies that analyzed frequency, clinical, biological, demographic, biomarkers, and prognostic features of s-OSCC and OSCC-dn according to PRISMA guidelines in PubMed, Scopus, Cochrane Library, and Google Scholar, up to January 31, 2023. Inclusion criteria were original English, Spanish, Portuguese, French, Italian, and German cross-sectional, cohort, and case-control studies. The quality of studies was assessed using the Agency for Research and Health Quality tool and the Newcastle-Ottawa Scale tool. RESULTS: The final selection included 40 studies. OSCC-dn and s-OSCC represent, respectively, 71% and 29% of cases of OSCC (P = .00), showing a higher percentage of T1 or of T1+T2 in s-OSCC (P < .0001). The association meta-analysis showed OSCC-dn with a significant association. The meta-analysis showed that s-OSCC was significantly associated with smaller tumor size, absence of distant metastases, relapses, male sex, and tumor sites different from tongue; and OSCC-dn was associated with more advanced tumor size, more regional and distant metastases, more advanced stages, and worse survival. CONCLUSIONS: S-OSCC was less frequent than expected. OSCC-dn seems to have specific clinical, biological, and prognostic features. Future perspectives on oral cancer prevention should address novel approaches and alternatives to screening, such as urgent referral of OSCC-dn.

BACKGROUND: Granular Cell Tumor (GCT) is an uncommon benign lesion in the oral cavity whose pathogenesis remains poorly understood. Due to their infrequent occurrence and similarity to other oral lesions, they are often forgotten during the initial clinical diagnosis. Therefore, understanding its prevalence, clinical and pathological characteristics is crucial for an accurate diagnosis and adequate management. METHODS: All cases diagnosed as GCTs in six Brazilian and Argentinian oral diagnostic centers were re-evaluated by HE staining, and clinical, demographic, and histopathological data were collected and evaluated. RESULTS: The series comprised 45 female (73.8%) and 16 male (26.2%), with a 2.8:1 female-to-male ratio and a mean age of 35.3 ± 16.9 years (range: 7-77 years). Most cases occurred on the tongue (n = 49; 81.6%) and presented clinically as asymptomatic papules or nodules (n = 50; 89.3%) with a normochromic (n = 25; 45.5%) or yellowish (n = 11; 20.0%) coloration and sizes ranging from 0.2 to 3.0 cm (mean ± SD: 1.40 ± 0.75 cm). Morphologically, most tumors were characterized by a poorly delimited proliferation (n = 52; 88.1%) of cells typically rounded to polygonal containing abundant, eosinophilic, finely granular cytoplasm. Pustulo-ovoid bodies of Milian were identified in all lesions (n = 61; 100%). Entrapment of skeletal striated muscle (n = 44; 72.1%) and nerve fibers (n = 42; 68.9%) were common findings. Pseudoepitheliomatous hyperplasia (PEH) was observed in 23 cases (39.0%). In only 27.7% of cases (n = 13) there was agreement between the clinical and histopathological diagnosis. Outcome information was available from 16 patients (26.2%), with clinical follow-up ranging from 4 to 36 months (mean 13.3 months), and none developed local recurrence. CONCLUSIONS: The clinical and histopathological features of GCTs were consistent with those described in previous studies. In general, these lesions have a predilection for the lateral region of the tongue in adult women. It is essential to consider GCTs in the differential diagnosis of yellow or normochromic papules and nodules in the oral cavity. Histopathological evaluation is essential for the definitive diagnosis and the prognosis is excellent.

BACKGROUND: Uremic stomatitis is often unfamiliar to healthcare professionals. This study presents five cases of uremic stomatitis, providing a comprehensive analysis of their demographic distribution, clinicopathological features, and management strategies based on existing literature. METHODS: Data were collected from centers across Brazil, Argentina, Venezuela, and Mexico. Electronic searches were conducted in five databases supplemented by manual scrutiny and gray literature. RESULTS: The series consisted of three men and two women with a mean age of 40.2 years. Lesions mostly appeared as white plaques, particularly on the tongue (100%). The median blood urea level was 129 mg/dL. Histopathological analysis revealed epithelial changes, including acanthosis and parakeratosis, with ballooned keratinocytes in the suprabasal region. Oral lesions resolved subsequent to hemodialysis in three cases (75%). Thirty-seven studies comprising 52 cases of uremic stomatitis have been described hitherto. Most patients were male (65.4%) with a mean age of 43.6 years. Clinically, grayish-white plaques (37.3%) and ulcers/ulcerations (28.9%) were common, particularly on the tongue (30.9%). Hemodialysis was performed on 27 individuals. The resolution rate of oral lesions was 53.3%. CONCLUSION: Earlier recognition of uremic stomatitis, possibly associated with long-term uremia, holds the potential to improve outcomes for patients with undiagnosed chronic kidney disease.

OBJECTIVE: Plasma cell mucositis (PCM) is a non-neoplastic plasma cell disorder of the upper aerodigestive tract with a high impact on life quality. Less than 70 cases were reported in the literature. The objective of this study was to report 2 cases of PCM. A concise review of the literature is also presented. STUDY DESIGN: Two cases of PCM that presented during the COVID-19 quarantine are reported. The inclusion criteria for the literature review were English-indexed case reports of the last 20 years. RESULTS: Cases were treated with meprednisone. As mechanical trauma was proposed as a triggering factor, its control was also considered. Patients were followed with no relapses. There were 29 studies included. The mean age was 57 years, with a male predominance, different clinical phenotypes, and intensely erythematous mucosa as a classical finding. The most frequent site was the lip, followed by the buccal mucosa. The final diagnosis is clinicopathologic. CD138 expression is a hallmark of plasma cells, frequently aiding PCM diagnosis. Plasma cell mucositis treatment is mostly symptomatic, and several therapeutic modalities have been mostly unsuccessful. CONCLUSIONS: Diagnosing plasma cell mucositis becomes challenging as many lesions may mimic other conditions. Consequently, in these cases, the diagnostic process should gather clinical, histopathologic, and immunohistochemical data.

Introduction: Drug-associated Maxillary Osteonecrosis is one of the most relevant adverse effects in treatment with antiresorptive drugs such as bisphosphonates and denosumab. Oncological conditions such as multiple myeloma, breast cancer, prostate, and bone-metabolic disorders such as osteoporosis lead the indications for these antiresorptive therapies. Treatment is complex because the disease is often refractory. Pharmacological, conservative and surgical treatments are described. Objective: The aim of this study is to report two clinical cases of MRONJ treated with two different therapeutic protocols and the analysis of the available literature on these aspects based on the clinical classification defined by the American Association of Oral and Maxillofacial Surgeons (AAOMS). Conclusion: Patients who develop clinical signs of great morbidity associated with MRONJ, may see their quality of life conditioned and suffer a worsening of their underlying pathology. MRONJ treatment is conditioned by the stage of the disease, its success depends on interdisciplinary management and strict medical and dental clinical follow-up, as well as rigorous monitoring to prevent or detect future recurrences early.
Introducción: La Osteonecrosis Maxilar asociada a Medicamentos (ONMAM) constituye uno de los efectos adversos más relevantes en el tratamiento con drogas antirresortivas como bifosfonatos y denosumab. Patologías oncológicas como mieloma múltiple, cáncer de mama, próstata, y alteraciones óseas-metabólicas como la osteoporosis lideran las indicaciones para estas terapias antirresortivas. El tratamiento es complejo debido a que muchas veces, la enfermedad es refractaria a la terapéutica aplicada. Se describen tratamientos farmacológicos, conservadores y quirúrgicos. Objetivo: El objetivo de este trabajo es reportar dos casos clínicos de ONMAM tratados con dos protocolos terapéuticos diferentes y el análisis de la literatura disponible en la actualidad sobre estos aspectos en base a la clasificación clínica definida por la American Association of Oral and Maxillofacial Surgeons (AAOMS). Conclusión: Los pacientes que desarrollan cuadros clínicos bucales de gran morbilidad como lo es ONMAM, pueden ver condicionada su calidad de vida y sufrir un agravamiento de su patología de base. El tratamiento de ONMAM está condicionado al estadio de la enfermedad, el éxito del mismo depende del manejo interdisciplinario y de un estricto seguimiento clínico médico y odontológico, así como también un riguroso monitoreo para evitar o detectar precozmente futuras recurrencias.

Chewing coca leaves is a habit still practiced in Bolivia, Peru and Argentina. There is scarce evidence in the relationship between this habit and development of oral squamous cell carcinoma (OSCC), some authors have found oral epithelial changes in coca chewers. This study aimed to present a case series of patients with a coca chewing habit that developed OSCC, in the absence of risk factors for oral cancer. Patients were evaluated in Hospital Señor del Milagro, Salta, Argentina. None of them had a relevant morbid history and presented intraoral tumors, with an ulcerated surface on the gingivobuccal complex. Coca chewing habit was recorded in all cases. Present cases could start discussions and new lines of researches focusing on the habit of coca leaves chewing as a risk factor for OSCC. It would be very useful to know the underlying mechanisms between this habit and a possible role in oral carcinogenesis.
RESUMO
BACKGROUND: Syphilis is the oldest sexually transmitted infectious disease in humanity. In the last decades, it was noted the re-emergence of the disease, and actually it remains an important public health problem. Oral mucosa could be affected by the infection. Oral manifestations are commonly associated with secondary syphilis. It was described that the labial commissure could be involved as a split papule, also known as false cheilitis (FC). However, this clinical manifestation is poorly described in current literature. AIM: This brief report aims to determine the frequency of FC in patients diagnosed with secondary syphilis in our institution during the period 2009-2019. MATERIAL & METHODS: A cross-sectional retrospective study was conducted using the medical records of the Oral Medicine Department, Facultad de Odontología, Universidad Nacional de Córdoba, Argentina. The cases included were patients with provisional diagnosis of secondary syphilis with oral manifestations, confirmed by laboratory tests. Collection of clinical and serological data was performed. Absolute and relative values were obtained. RESULTS: In this study, 58 patients (26 males and 32 females) with an average age of 34.70 years old were included. The frequency of false cheilitis in these patients was 13% (8/58). All these patients with false cheilitis and secondary syphilis were young females with an average age of 25.12 years old. These lesions presented as angular cheilitis with an unilateral pattern with painful fissured papules associated with other oral lesions such as fissures, intraoral papules, tongue depapillation, white or red plaques, and the evidence of submandibular lymphadenopathies when examining the head and neck region. CONCLUSION: Our findings suggest that when angular cheilitis presents in young females as a painful, unilateral lesion, in the clinical context of other lesions and lymphadenopathies in the head and neck region, it could represent a suspicious clinical sign of syphilis. Considering the global re-emergence of sexually transmitted diseases, dentists should be aware of the oral clinical manifestations of syphilis as they play a significant role in the early detection of these conditions.

Oral squamous cell carcinomas (OSCC) are caused by chronic tobacco abuse. In this regard, the carcinogenic potential of smoking and smokeless forms of tobacco, including chewing tobacco and moist/dry snuff, has been widely documented. However, the effects of tobacco-containing products such as creamy snuff on oral health have not been widely reported. Here, we report on the clinical presentation of a patient with OSCC induced by concurrent chewing tobacco and creamy snuff use. The development and progression of mucosal carcinogenesis in the context of mixed tobacco use habits is discussed. With the increased availability of newer tobacco-containing products, it is important for clinicians to be aware of these products in the marketplace, including dentifrices and nicotine pouches, and counsel their patients regarding their health risks.

Introduction: Human Papilloma Virus could infect human epithelia, including cervical and oral keratynocites, leading to the development of dysplastic or malignant changes. Regarding the oral mucosa, leukoplakia is the most potentially malignant disorder associated with Papilloma Virus coinfection. Objective: the aim of this report is to present a case of a young woman with a previous history of a high-risk cervical lesion associated with Human Papillomavirus and an oral leukoplakia associated with the same viral infection using immunohistochemical techniques. Methodology: the case was recorded and treated at the Oral Medicine Department, Facultad de Odontología, Universidad Nacional de Córdoba. The patient was monitored and followed-up during three years, with no evidence of disease recurrence. Conclusion: due to the increased rates of Oral Squamous Cell Carcinomas among young patients in recent years and a supposed relationship to Human Papillomavirus infection, this case reflects a challenge not only in the diagnosis, treatment and follow-up, but also the urgent need to approach these patients in a transdisciplinary perspective. Since most of these viral lesions are usually transmitted sexually, it is necessary to promote awareness in the population about prevention and protection measures against sexually transmitted infections.
Introducción: El virus de Papiloma Humano infecta epitelios del organismo como el cervical o el bucal pudiendo generar cambios displásicos o malignos. Clínicamente, en la mucosa bucal la lesión potencialmente maligna más asociada a una coinfección viral es la leucoplasia. Objetivo: el objetivo de este trabajo es presentar un caso de una joven con antecedentes de lesiones cervicales de alto grado asociadas a infección por virus de Papiloma Humano y una lesión de leucoplasia bucal asociada a la misma infección viral mediante técnicas de inmunohistoquímica. Metodología: el caso fue registrado y tratado en la Cátedra de Estomatología "A" de la Facultad de Odontología, Universidad Nacional de Córdoba, con un seguimiento clínico de tres años, sin evidencia de recurrencias de la enfermedad. Conclusión: debido al incremento en los últimos años de carcinomas bucales en pacientes jóvenes y una supuesta relación a factores de riesgo como la infección por Virus de Papiloma Humano, este caso refleja un desafío no solo en el diagnóstico, tratamiento y seguimiento, sino también la imperiosa necesidad de abordar estos pacientes en forma transdisciplinaria. Ya que la mayoría de estas lesiones virales suelen transmitirse por vía sexual, es necesario promover conciencia en la población sobre las medidas de prevención y protección ante infecciones de transmisión sexual.
