The importance of early treatment of oral squamous cell carcinoma: Case report.

BACKGROUND: Oral squamous cell carcinoma (OSCC) is frequently diagnosed at an advanced stage, with the five-year survival rate varying around 50%, however, ifs the sooner OSCC in early-stage is treated, the lower the chances of recurrence and death. In this study, we described an OSCC diagnosed early, highlighting how the early surgical excision prevents the morbidity. CASE REPORT: A 74-year-old man presented a whitish and symptomatic plaque and a discreet ulcerated area on the right lateral border of the tongue. Due to close contact with the second inferior molar, a clinical diagnosis of a frictional keratosis was suspected, however as the lesion persisted after two weeks of follow-up, an incisional biopsy was performed and the microscopic features revealed an OSCC. Early surgical resection was performed, preventing the morbidity and improve benefits to patient. CONCLUSION: OSCC can manifest of several clinical forms, including indolent appearances, which can delay the diagnosis, and consequently the prognosis. Further, it is important to recognize and not neglect any intraoral lesions, in order to avoid the far more invasive surgery that a more advance disease would imply.

A Rare Case of Mandibular Aspergillus Osteomyelitis in an Immunocompetent Patient.

Aspergillosis is a fungal infection caused by Aspergillus species, which is contracted through spores that colonize the respiratory tract, causing rhinosinusitis and pulmonary infections. Oral aspergillosis is rare and, when present, may cause soft tissue and bone destruction, generally in immunodeficient patients. Mandibular Aspergillus osteomyelitis is even rarer, with few cases reported in the literature. A 57-year-old Caucasian woman was referred for the evaluation of painful recurrent swelling in the anterior mandibular alveolar ridge, with purulent drainage, previously treated with multiple surgical debridement procedures and antibiotics without success. The patient was otherwise systemically healthy. Surgical debridement was performed and histopathological examination showed osteomyelitis associated with Aspergillus species. Therapy with oral itraconazole (400 mg per day) was administered for 3 months, resulting in complete resolution. No recurrence was detected after 15 years of follow-up. The patient was rehabilitated with dental implants. In conclusion, non-bacterial microorganisms, such as Aspergillus, should be considered in cases of mandibular osteomyelitis that do not heal after surgical debridement and antibiotic therapy.

The role of osteopontin in oral cancer: A brief review with emphasis on clinical applications.

Osteopontin (OPN) is a calcium-binding glycol-phosphoprotein present in many physiologic and pathological processes. This protein can control bone cell adhesion, osteoclastic activity, and bone matrix mineralization. However, its participation in pathological processes such as atherosclerosis, sarcoidosis, tuberculosis, and cancer have been described. Some studies have shown that OPN may participate in the development and progression of oral cancer. Although the role of OPN in oral cancer is not fully understood, some studies have suggested that this protein may induce malignant phenotype of cells by activation of PI3K/AKT/mTOR pathway, which favors cell proliferation, invasion, metastasis, angiogenesis, and failure of treatment. This review discusses the possible mechanism of involvement of OPN in oral cancer and its potential clinical application in diagnosis and prognosis.

Oral squamous cell carcinoma around dental implants: a systematic review.

OBJECTIVE: This systematic review aimed to evaluate the epidemiologic profile, screen for possible risk factors, and evaluate the spectrum of clinical characteristics of oral squamous cell carcinoma (OSCC) around dental implants (DIs). METHODS: The systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta- Analyses statement. RESULTS: Thirty-three articles met the eligibility criteria. In total, the sample consisted of 63 patients, and women comprised the majority (55.5%). The mean age of patients was 66.7 years. Oral potentially malignant disorders were reported in 46% of patients, of which 65.5% occurred in women. The most common lesion found in women was oral lichen planus (52.6%). In 88.8% of patients OSCC around DIs occurred in the mandible, and the most common clinical appearance of the lesions was an exophytic mass (46%). Most of these lesions were initially treated as peri-implantitis. CONCLUSIONS: Most patients with OSCC around DIs were women without known risk factors. It is important to emphasize that these lesions may present clinical and radiographic features that could resemble peri-implantitis, which can lead to delay in the diagnosis and subsequent treatment.

Epidemiological profile and clinical implications of oral squamous cell carcinoma adjacent to dental implants.

OBJECTIVES: Describe the epidemiological profile of patients with oral squamous cell carcinoma (OSCC) around dental implants (DI), investigate the spectrum of clinical and pathological characteristics, and discuss the implications of diagnosis delay of these lesions. METHODS: Retrospective analysis of patients treated of OSCC adjacent to DI at A.C. Camargo Cancer Center between 2009 and 2020. RESULTS: Thirty one patients were identified, being women the majority (58.1%). The mean age of the patients was 68.8 years. Never smoker corresponds to 46.9% and never alcohol consumer to 54.9% of the sample. OPMD was reported in 45.2% of patients, affecting mainly women (78.5%). Leukoplakia (63.7%) followed by oral lichen planus (36.3%) was the most common OPMD found in women. OSCC adjacent to DI occurred in the inferior gingiva/alveolar mucosa in 48.3% of cases, and ulceration was the most common clinical appearance (87%). Peri-implantitis (PI) was initial clinical diagnosis in 16.1% of cases. CONCLUSIONS: Oral squamous cell carcinoma adjacent to DI was more common in women over 70 years old, non-smokers and non-drinker, and the majority had oral leukoplakia before the diagnosis of OSCC. OSCC may present clinical and radiographic features that resemble PI which can delay the diagnosis and impair the prognosis.

Epidemiological study of bucomaxilofacial trauma in a Paraíba reference hospital. / Estudo epidemiológico do trauma bucomaxilofacial em um hospital de referência da Paraíba.

OBJECTIVE: to study the epidemiological data of patients suffering from buccomaxillofacial trauma treated at a referral hospital in the State of Paraíba. METHODS: we conducted a cross-sectional study of inductive approach, with a comparative statistical procedure and research technique by field direct documentation. The sample comprised hospital records obtained from January 2016 to December 2017 of patients attended by the Service of Buccomaxillofacial Surgery and Traumatology of this hospital, and consisted of 332 patients according to the study's eligibility criteria. Two previously calibrated examiners collected and analyzed the data, both descriptively and inferentially. RESULTS: males sustained the majority of facial trauma (83.1%), mainly in the third decade of life (32.2%). Motorcycle accidents were the most common etiology of trauma for both genders. In relation to inferential statistics with a margin of error of 5%, there was no significant association (p>0.05) between the genders and the trauma etiological factors. The bones of the nose (38.2%) were the most affected bones and the most frequent soft tissue injury was edema, in 50.9% of cases. Only 20.8% of the patients with bone fractures were polytraumatized. CONCLUSION: the victims of oral and maxillofacial trauma attended at our hospital are predominantly men in the third decade of life, involved in motorcycle accidents and sustaining lesions in the nose bones nose.

OBJETIVO: estudar os dados epidemiológicos de pacientes vítimas de traumas bucomaxilofaciais atendidos em um hospital de referência da Paraíba. MÉTODOS: estudo transversal de abordagem indutiva com procedimento estatístico comparativo e técnica de pesquisa por documentação direta em campo. O universo foi constituído dos prontuários hospitalares obtidos de janeiro de 2016 a dezembro de 2017 de pacientes atendidos pelo Serviço de Cirurgia e Traumatologia Bucomaxilofacial desse hospital. A amostra foi composta por 332 pacientes de acordo com os critérios de elegibilidade do estudo. A coleta de dados foi realizada por dois examinadores previamente calibrados e os dados foram analisados descritiva e inferencialmente. RESULTADOS: os pacientes do sexo masculino foram mais acometidos por trauma facial (83,1%), principalmente na terceira década de vida (32,2%). Acidentes motociclísticos foram a etiologia mais comum de trauma para ambos os sexos. Em relação à estatística inferencial com margem de erro fixada em 5%, não foi observada associação significativa (p>0,05) entre os sexos e os fatores etiológicos do trauma. Os ossos do nariz (38,2%) foram os ossos mais afetados e a lesão mais frequente de partes moles foi o edema, em 50,9% dos casos. Apenas 20,8% dos pacientes com fraturas ósseas foram politraumatizados. CONCLUSÃO: as vítimas de traumatismo bucomaxilofacial atendidas em nosso hospital são predominantemente homens na terceira década de vida, envolvidos em acidentes motociclísticos e com lesões em ossos do nariz.
