Análise do diagnóstico citopatológico realizado em pacientes atendidos na clínica de estomatologia do curso de odontologia da Universidade Federal Fluminense, Nova Friburgo / RJ / Diagnostic cytopathologicalanalysis performed in patients attended by the stomatology clinic of the Universidade Federal Fluminense, Nova Friburgo / RJ

A citopatologia é uma técnica que propicia diagnósticos rápidos para lesões em mucosas, além de ser bastante acessível do ponto de vista econômico. Na odontologia, pode ser um bom exame auxiliar no diagnóstico de lesões bucais, principalmente lesões infecciosas, bem como na detecção precoce do câncer de boca. Objetivos: estabelecer a técnica de citopatologia no laboratório de Patologia Oral do Instituto de Saúde de Nova Friburgo da UFF, bem como avaliar dados demográficos e discutir os diagnósticos citopatológicos desses pacientes. Métodos: foram selecionados 90 pacientes atendidos na clínica de Estomatologia da UFF-NF com lesões orais que tinham indicação para realização da citopatologia oral. Após obtenção de dados demográficos, a coleta de material foi feita, seguida da realização do esfregaço em duas lâminas de vidro. Resultados: Dos 90 pacientes, 54 (60%) eram mulheres e 36 (40%) homens. A idade dos pacientes variou de 30 a 82 anos, com média de 56,60 anos. Desses pacientes, 23 (26%) declararam-se tabagistas, 27 (30%) declararam-se etilistas e 77 (86%) eram usuários de próteses dentárias. Os esfregaços dos 90 pacientes foram diagnosticados de acordo com as classes de Papanicolaou, sendo a maioria, 84 pacientes (93%), diagnosticada como Classe II. Desses 84 pacientes, 34 (40,4%) apresentaram candidíase. Conclusão: após a realização deste trabalho, além da técnica de citopatologia ser estabelecida, pode-se perceber que os esfregaços inflamatórios e apresentando fungo foram predominantes, o que demonstra a boa capacidade diagnóstica da técnica de citopatologia para lesões infecciosas(AU)

Objectives: to establish the technique of cytopathology in the laboratory of Oral Pathology of the Institute of Health of Nova Friburgo of the UFF, as well as to evaluate demographic data and to discuss the cytopathological diagnoses of these patients. Methods: 90 patients attended at the Stomatology clinic of the UFF-NF with oral lesions that had been indicated for oral cytopathology were selected. After obtaining demographic data, the material was collected, followed by the smearing on two glass slides. Results: Of the 90 patients, 54 (60%) were women and 36 (40%) were men. The patients' ages ranged from 30 to 82 years, with a mean of 56.60 years. Of these patients, 23 (26%) declared themselves smokers, 27 (30%) declared themselves alcoholics and 77 (86%) were users of dental prostheses. The smears of the 90 patients were diagnosed according to the classes of Papanicolau, being the majority, 84 patients (93%), diagnosed as Class II. Of these 84 patients, 34 (40.4%) presented candidiasis. Conclusion: after this work, besides the cytopathology technique was established, it can be noticed that the inflammatory smears and presenting fungus were predominant, which demonstrates the good diagnostic capacity of the cytopathology technique for infectious lesions(AU)

Microbiological, lipid and immunological profiles in children with gingivitis and type 1 diabetes mellitus.

OBJECTIVE: The aim of this study was to compare the prevalence of periodontal pathogens, systemic inflammatory mediators and lipid profiles in type 1 diabetes children (DM) with those observed in children without diabetes (NDM), both with gingivitis. MATERIAL AND METHODS: Twenty-four DM children and twenty-seven NDM controls were evaluated. The periodontal status, glycemic and lipid profiles were determined for both groups. Subgingival samples of periodontal sites were collected to determine the prevalence of periodontal microorganisms by PCR. Blood samples were collected for IL-1-ß, TNF-α and IL-6 analysis using ELISA kits. RESULTS: Periodontal conditions of DM and NDM patients were similar, without statistical differences in periodontal indices. When considering patients with gingivitis, all lipid parameters evaluated were highest in the DM group; Capnocytophaga sputigena and Capnocytophaga ochracea were more prevalent in the periodontal sites of DM children. "Red complex" bacteria were detected in few sites of DM and NDM groups. Fusobacterium nucleatum and Campylobacter rectus were frequently found in both groups. Similar levels of IL-1-ß, TNF-α and IL-6 were detected in DM and NDM children. CONCLUSION: Clinical and immunological profiles are similar between DM and NDM children. The presence of Capnocytophaga sputigena and Capnocytophaga ochracea were associated with gingivitis in DM children.

Benign fibrous histiocytoma of the tongue: a case report / Histiocitoma fibroso benigno em língua: relato de caso

The fibrous histiocytoma is a soft tissue neoplasm that affects the dermis and the subcutaneous tissue, rarely is found in the oral cavity and perioral regions, and is originated from the proliferation of fibroblasts and histiocytes. The objective of this paper is to report a case of Benign Fibrous Histiocytoma in a 30-year-old male patient, complaining of a painless nodule in the tongue for about six months. With diagnostic clinical hypotheses of Fibrous Hyperplasia, Neurofibroma, Traumatic Neuroma, Fibrous Histiocytoma, Granular Cell Tumor or Ectomesenchymal Chondromyxoid Tumor a excisional biopsy was performed. The histopathological examination revealed a non-encapsulated proliferation of spindle cells with some giant multinucleated cells in the periphery of the lesion. Immunohistochemical reactions were performed, staining only for vimentin in the spindle cells and for CD68 in the multinucleated giant cells. According to these characteristics, the final diagnosis was Benign Fibrous Histiocytoma. The correct diagnosis of spindle shaped cell neoplasia must be performed with the aid of histopathological analysis and immunohistochemistry, mainly because the morphological similarities with other benign and malignant lesions.

O Histiocitoma Fibroso é uma neoplasia de partes moles que acomete a derme e o tecido subcutâneo, raramente é encontrado na cavidade oral e regiões periorais, e tem origem a partir da proliferação de fibroblastos ou histiócitos. O objetivo deste artigo é relatar um caso de Histiocitoma Fibroso Benigno em um paciente masculino, 30 anos de idade, com um nódulo indolor, bem delimitado, com duração de cerca de seis meses, localizado no dorso anterior da língua. Com as hipóteses clínicas diagnósticas de Hiperplasia Fibrosa, Neurofibroma, Neuroma Traumático, Histiocitoma Fibroso, Tumor de Células Granulares e Tumor Condromixoide Ectomesenquimal uma biópsia foi realizada sob anestesia local e a lesão foi fixada em formol a 10% e enviada para análise histopatológica. O exame histopatológico revelou uma proliferação não-encapsulada de células fusiformes com algumas células gigantes multinucleadas na periferia da lesão. A marcação imunohistoquímica foi positiva para CD68 nas células gigantes multinucleadas e para vimentina nas células fusiformes. O diagnóstico final foi de Histiocitoma Fibroso Benigno. Para um diagnóstico correto, este deve ser feito correlacionando características clínicas, análise histopatológica e imunohistoquímica devido à similaridade microscópica do Histiocitoma Fibroso com outras lesões com aspecto fusocelular, assim como similaridade clínica com outras lesões benignas e malignas.(AU)

Carcinoma de células escamosas oral em pacientes jovens: uma realidade que deve ser reconhecida pelos dentistas / Oral squamous cell carcinoma in young patients: a reality that must be recognized by dentists

O carcinoma de células escamosas (CCE) é a neoplasia maligna mais comum da boca. O diagnóstico definitivo requer que o cirurgião dentista tenha conhecimento clínico e suspeite da possível natureza maligna da lesão, de forma que indique corretamente os exames complementares. Embora a prevalência seja mais expressiva em homens com idade entre 50 e 70 anos e os fatores associados mais comuns sejam o tabagismo e etilismo, os casos em pacientes com idade abaixo dos 40 anos têm aumentado no mundo todo. Neste grupo de pacientes jovens há uma proporção semelhante entre homens e mulheres acometidos, o que deve ser, portanto, também considerado pelo cirurgião dentista. Assim, este trabalho relatará o caso de um paciente jovem com CCE de boca, ressaltando a necessidade da correlação clínico-patológica e o papel do estomatologista e do patologista oral no estabelecimento do diagnóstico definitivo, bem como a importância do diagnóstico precoce no tratamento e prognóstico destes casos. Paciente do sexo masculino, 22 anos, não tabagista e não etilista, foi encaminhado pelo ortodontista ao estomatologista para avaliação de uma úlcera localizada na borda lateral posterior de língua, assintomática, com histórico de aproximadamente 2 meses. Foi realizada a biópsia incisional e a análise histopatológica concluiu o diagnóstico em carcinoma de células escamosas. O paciente foi submetido à excisão cirúrgica com glossectomia parcial e esvaziamento cervical. Foi realizada a técnica de hibridização in situpara identificar a presença do papiloma vírus humano, cujo resultado foi negativo. O paciente encontra-se bem e em acompanhamento há 8 meses, sem sinais de recorrências (AU).

Squamous cell carcinoma (SCC) is the most common oral malignant neoplasm. The definitive diagnosis requires that the dentist has clinical knowledge and suspects the possible malignant nature of the lesion, so that he can correctly indicate the complementary examinations. Although the prevalence is more significant in men aged between 50 and 70 years old and the most common associated factors are smoking and alcoholism, cases in patients under 40 years old have increased worldwide. In this group of young patients there is a similar proportion between men and women affected, which should therefore also be considered by the dentist. This article will report the case of a young patient with oral SCC, highlighting the need for clinicopathological correlation and the stomatologist and oral pathologist role in establishing the definitive diagnosis, as well as the importance of early diagnosis in the treatment and prognosis of these cases. A 22-year-old male patient non-smoker, non-alcoholic was referred by the orthodontist to the stomatologist for evaluation of an ulcer located at the lateral border of the tongue, asymptomatic, with a history of approximately 2 months. An incisional biopsy was performed and the histopathological analysis concluded the diagnosis of squamous cell carcinoma. The patient underwent surgical excision with partial glossectomy and neck dissection. In situ hybridization technique was performed to identify the presence of human papilloma virus, whose result was negative. The patient is well and in 8 months followup has showed no recurrences signs (AU).

Objetivo: relatar caso clínico de tumor odontogênico adenomatoide (TOA), enfatizando suas características e diagnósticos diferenciais. Relato de caso: paciente masculino, 16 anos, apresentando lesão radiolúcida, unilocular, associada ao dente 24 incluso. Sob as hipóteses de TOA, cisto dentígero, tumor odontogênico cístico calcificante e ameloblastoma unicístico, foi realizada biópsia excisional. Na microscopia, observou-se parênquima contendo estruturas tubulares e áreas semelhantes à roseta e cribriformes, estabelecendo o diagnóstico de TOA. Conclusão: o reconhecimento das características clínicas, radiográficas e histopatológicas do TOA é essencial para guiar o processo para se estabelecer o diagnóstico definitivo e, consequentemente, permitir o tratamento adequado do paciente.

Objective: to report a case of adenomatoid odontogenic tumor (AOT), highlighting its features and differential diagnosis. Case report: a 16-year-old male with a unilocular radiolucent lesion involving the unerupted 24th tooth. Considering AOT, dentigerous cyst, calcifying cystic odontogenic tumor, and unicystic ameloblastoma as the clinical diagnoses, an excisional biopsy was performed. Microscopic analysis revealed a parenchyma containing tubular structures and roset-like areas, establishing a diagnosis of AOT. Conclusion: the acknowledgement of clinical, radiographic, and microscopic features of AOT is essential to guide a definitive diagnosis and, as a consequence, to enable a suitable treatment of the patient.

Time-resolved fluorescence spectroscopy for clinical diagnosis of actinic cheilitis.

Actinic cheilitis is a potentially malignant disorder of the lips. Its first cause is believed to be UV sun radiation. The lesion is highly heterogeneous, making the choice of area to be biopsied difficult. This study exploits the capabilities of time-resolved fluorescence spectroscopy for the identification of the most representative area to be biopsied. A preliminary study was performed on fourteen patients. A classification algorithm was used on data acquired on nine different biopsies. The algorithm discriminated between absent, mild, and moderate dysplasia with a sensitivity of 92.9%, 90.0%, and 80.0%, respectively. The false positive rate for healthy tissue (specificity) was 88.8%.

Sialolito de grandes dimensões no ducto da glândula submandibular / Large sialolith in the submandibular gland duct

O objetivo deste trabalho é descrever o caso de um sialolito de grandes dimensões em glândula submandibular. Paciente do sexo feminino, leucoderma, 53 anos, procurou o cirurgião-dentista queixando-se de xerostomia, dor e inchaço na região de assoalho bucal, principalmente observado durante as refeições. O exame físico revelou uma tumefação em região submandibular esquerda, sensível a palpação, além de aumento de volume intra-oral firme, na região sublingual esquerda. Ao ordenhar a glândula submandibular, houve saída de pus. A radiografia oclusal inferior evidenciou extensa imagem radiopaca extensa, bem delimitada, cilíndrica e alongada. A associação dos exames clínicos e radiográficos levou ao diagnóstico de cálculo salivar. Foi realizada excisão cirúrgica da lesão sob anestesia local, com preservação da glândula submandibular. O exame anatomopatológico do cálculo revelou, na macroscopia, uma peça cirúrgica de consistência dura e cor amarela medindo 2,2 cm de diâmetro e, na microscopia, a presença de laminações concêntricas de material calcificado. A paciente encontra-se em acompanhamento há 2 anos e 8 meses, sem queixas de função glandular ou fluxo salivar, sem aumento de volume e exame radiográfico sem alterações. Apesar das grandes dimensões do sialolito, sua localização próxima à saída do dueto permitiu um tratamento conservador com bons resultados para a paciente.

This paper aims to describe a case of a large submandibular sialolith. A 53-year-old Caucasian female looked for for her dentist complaining of xerostomia, pain and swelling in the floor of the mouth, mainly observed during meals. The physical exam revealed a tender swelling on palpation in the left submandibular region, and also a firm intraoral swelling was detected in the left sublingual region. It was possible to draw pus from the submandibular gland. Mandibular occlusal radiography showed an extensive cylindrical and elongated, well-defined radiopaque image in the floor of the mouth. The association of clinical and radiographic findings led to the diagnosis of salivary calculus. The lesion was submitted to surgical excision under local anesthesia and the submandibular gland was maintened. Macroscopic analysis revealed a yellow and hard in consistency specimen, measuring 2.2 cm in length, and microscopic analysis revealed the presence of concentric laminations of calcified material associated with . The patient is being followed up for 2 years and 8 months, with no complaints of salivary flow or gland dysfunction, without gland swelling and no radiographic changes. Despite it being a large sialolith, its location near the exit of the duct allowed a conservative treatment with satisfactory aesthetic and functional results for the patient.

Oral myofibromas: report of two cases and review of clinical and histopathologic differential diagnosis.

Myofibroma is a benign mesenchymal neoplasm composed of myofibroblasts which has been described with different synonyms since the first report in 1951. It may show clinical and histologic features that may be misinterpreted as a malignancy. We describe 2 cases of oral myofibromas affecting infants; the first one showed a rapid growth with teeth displacement and ulceration; the second one presented a relatively slow growth with an indolent course. Differential diagnosis included benign and malignant mesenchymal neoplasms, salivary gland tumors, and reactive processes. Microscopic analysis of both lesions revealed a spindle cell tumor with immunoreactivity for vimentin, muscle-specific actin, and specific smooth muscle isoform alpha-actin, rendering the diagnoses of myofibroma. The patients were treated with surgical excision, and both are in follow-up without any signs of recurrence. Myofibroma presents a wide range of differential diagnosis, including benign and malignant neoplasms. Therefore, accurate diagnosis may avoid an unnecessary aggressive therapy.
