ABSTRACT

Abstract Pathological parameters have been indicated as tumor prognostic factors in oral carcinoma. Objective: The objective of this study was to investigate the impact of pathological parameters on prognosis of patients affected only by tongue and/or floor of the mouth squamous cell carcinoma (SCC). Methodology: In total, 380 patients treated in the Brazilian National Cancer Institute (INCA) from 1999 to 2006 were included. These patients underwent radical resection followed by neck dissection. The clinical and pathological characteristics were recorded. The Kaplan-Meier method and Cox proportional hazards model were used in survival analysis. Overall survival (OS), cancer-specific survival (CSS) and disease-free interval (DFI) were estimated. Cox residuals were evaluated using the R software version 3.5.2. Worst OS, CSS and DFI were observed in patients with tumors in advanced pathological stages (p<0.001), with the presence of perineural invasion (p<0.001) and vascular invasion (p=0.005). Results: Advanced pathological stage and the presence of a poorly differentiated tumor were independent prognostic factors for OS and CSS. However, advanced pathological stage and perineural invasion were independent predictors of a shorter OS, DFI and CSS. Conclusion: Pathological stage and perineural invasion were the most significant pathological variables in survival analysis in tongue and/or floor of the mouth SCC.

ABSTRACT

Abstract Lesions in the floor of the mouth can be a challenging diagnosis due to the variety of pathological conditions that might be found in this area. Within a broad range of lesions, attention has to be addressed to those that require specific management, such as a dermoid cyst (DC) and a ranula. Especially in pediatric patients, in whom the failure of diagnosis can postpone the correct treatment and cause sequelae later in life. DC, a developmental anomaly, is managed primarily by surgical resection. On the other hand, ranula is a pseudocyst that may be treated by marsupialization. This article reports a large and painful lesion in the floor of the mouth in a pediatric patient. With a diagnostic hypothesis of ranula, two surgical interventions were performed, but there were recurrences of the lesion. Subsequently, the patient was referred to the Oral and Maxillofacial Surgery Unit for re-evaluation. Computed tomography showed a semi-transparent image suggesting a cystic formation. Another surgical procedure was performed where the lesion was completely removed. Anatomopathological analysis confirmed the diagnosis of DC. The five-year follow-up showed no signs of recurrence. This article indicates that although DC in the floor of the mouth is rare, it should be considered in the differential diagnosis of other diseases in this area. This precaution may be particularly important in the following circumstances: 1) Similar lesions that have different therapeutic approaches and, 2) To prevent future sequelae in pediatric patients.

ABSTRACT

El quiste epidermoide es un quiste de tejido blando de origen ectodérmico que se encuentra con poca frecuencia en la cavidad oral. Clínicamente se caracteriza por ser una lesión asintomática, de larga evolución, recubierta con mucosa normal, y usualmente se diagnostica cuando el aumento de volumen genera molestias en el paciente. El tratamiento varía de acuerdo a su tamaño y localización anatómica. Presentamos el caso de una paciente de 29 años de edad con un quiste epidermoide de gran tamaño, en reloj de arena, del piso de boca. Se describen las características específicas histológicas y clínicas, y se discute la conducta terapéutica seguida.


The epidermoid cyst is a soft tissue cyst of ectodermal origin found infrequently in the oral cavity. Clinically, it is characterized by an asymptomatic lesion, of long evolution, covered with normal mucosa, and is usually diagnosed when the volume increases and generates patient discomfort. Treatment varies according to its size and anatomical location. We report the case of a 29 year old patient with a large, hourglass shaped, epidermoid cyst in the floor of the mouth. Specific histological and clinical characteristics are described and the therapeutic behavior followed is discussed.

ABSTRACT

Los lipomas son tumores de tejido conjuntivo compuestos por células adiposas que pueden aparecen en cualquier parte del cuerpo. En la cavidad bucal es poco frecuente encontrar estos tumores; cuando llegan a presentarse, los sitios más comunes son la mucosa bucal vestibular, lengua, labios y el piso de la boca, siendo este último el menos frecuente. Presentamos el reporte de un caso de lipoma en piso de boca en un paciente masculino de 34 años de edad, quien en la exploración clínica presentaba aumento de volumen en piso de boca del lado derecho, de corta evolución. Se realizó escisión local conservadora bajo anestesia local, con reporte histopatológico de lipoma.


Lipomas are connective tissue tumors composed of adipose cells, which can appear anywhere on the body. Though rare in the oral cavity, when they do appear the most common sites are the buccal mucosa, tongue, lips, and, least commonly, the floor of the mouth. We present a case report of a lipoma of floor of mouth in a 34-year-old male patient, who, upon clinical examination, showed an increase in volume of short evolution on the right side of the floor of the mouth. A conservative local excision was performed under local anesthesia, with the histopathological report of lipoma.

ABSTRACT

Lipomas of the oral cavity are not uncommon, but its location in the floor of the mouth is a rare entity. They are soft tissue mesenchymal neoplasm’s of mature adipose tissues. Its overall incidence of occurrence in the oral cavity is 1-5% of all benign oral lesions. Oral lipomas can occur at various anatomic sites, including buccal mucosa, tongue, major salivary glands, and floor of the mouth. Although benign in nature their progressive growth may cause interference with speech and mastication due to the tumors’ dimension. In this article, the author reports an unusually large lipoma occurring in the floor of the mouth in a 44-year-old female patient. The present case is worth presentation considering the relative rarity with respect to the location and the size of the lesion.

ABSTRACT

Fractured and displaced genial tubercles are a relatively rare happening in the field of oral and maxillofacial trauma. These tubercles are attached to the geniohyoid and genioglossus muscles, which are associated with lingual mobility and deglutition. Separation of these unilateral tubercles can lead to sublingual pain, dysphagia and difficulty in swallowing. Review of literature shows that only <15 cases of fractured genial tubercles have been reported in the English literature until now. Surgical interventions have been rarely reported in the literature as most of the cases have been managed conservatively. We report a case of fractured genial tubercle, following trauma, which was intervened surgically.

ABSTRACT

O seio maxilar apresenta formato distinto e volume variável entre as pessoas e seu assoalho pode ser encontrado em íntimo contato com as raízes dos dentes posteriores, podendo haver protrusão dessas raízes em seu interior. Tal proximidade é de grande relevância frente aos casos de comunicação bucossinusal em potencial ou pela possibilidade de desenvolvimento de um quadro infeccioso de origem odontogênica, em que esse pode vir a se estender para o interior do seio maxilar. Existe uma ausência de trabalhos na literatura acerca da relação estabelecida entre dentes posteriores e o seio maxilar em pessoas com fissura labiopalatina. O objetivo do presente estudo foi identificar e comparar a relação entre o assoalho do seio maxilar e os ápices radiculares dos dentes posteriores em imagens de tomografia computadorizada de feixe cônico em pessoas sem fissura labiopalatina e com fissura transforame incisivo unilateral e bilateral. Foram avaliados 100 indivíduos sem anomalias craniofaciais e 112 com fissura transforame incisivo unilateral ou bilateral, não sindrômicos, utilizando o programa i-CAT® Vision, onde a relação estabelecida pelas estruturas foi convencionada sendo, tipo 0 ou ausência de contato entre as estruturas, tipo 1 ou relação de íntimo contato entre as estruturas sem protrusão radicular no interior do seio maxilar e tipo 2 ou relação de íntimo contato entre as estruturas com protrusão radicular no interior do seio maxilar. Foi utilizado o teste do qui-quadrado para comparar os achados entre os grupos estudados, considerando valor estatisticamente significante quando p≤ 0,05. Foi avaliada a relação do assoalho do seio maxilar com 1679 dentes, totalizando 3664 raízes onde 1883 (51,3%) foram classificadas como tipo 0, 1456 (39,7%) tipo 1 e 325 (8,8%) do tipo 2. Houve diferença estatisticamente significante para a raiz palatina do dente 18 entre os grupos com fissura unilateral e bilateral (p = 0,011), para a raiz mesiovestibular do dente 18...


The maxillary sinus has a remarkable feature and a variable volume among people where the inferior wall may be found in an intimate relation with the posterior teeth roots protruding or not inside the antrum. This proximity is of great relevance considering a potential oroantral communication or the spreading of an odontogenic infection into the maxillary sinus. There is a lack of evidence into the literature regarding the relationship between posterior teeth roots and the maxillary sinus in non-syndromic complete cleft lip and palate patients. This study aimed to evaluate and compare cone beam computed tomography images regarding the relationship between the posterior teeth roots and the maxillary sinus floor in non-cleft lip and palate patients and non-syndromic complete unilateral and bilateral cleft lip and palate patients. Images were interpreted using the i-CAT® Vision software including 100 noncleft patients and 112 presenting non-syndromic complete unilateral and bilateral cleft lip and palate. The relationship between teeth roots and the maxillary sinus floor was established as type 0 or no contact between these structures, type 1 or close contact without root protrusion into the sinus and type 2 or close contact with root protrusion into the sinus. The chi-square test, considering a statistically significant value where p≤0,05, was used to compare data between different groups. The sample included 1679 teeth and 3664 roots where 1883 (51,3%) were classified as type 0, 1456 (39,7%) as type 1 and 325 (8,8%) as type 2. There were statistically significant differences for tooth 18 palatine root between both complete cleft lip and palate groups (p = 0,011), for tooth 18 mesiobuccal root between noncleft and the bilateral groups (p = 0,046) and between both complete cleft lip and palate groups (p = 0,016) and for tooth 24 buccal root between non-cleft and the bilateral group (p = 0,001). Complete unilateral and bilateral cleft lip and palate...

ABSTRACT

Sialolithiasis is the presence of calculus within the ductal system of a salivary gland. Among the diagnostic methods are inspection, palpation, checking the amount of saliva secreted and the identification of a sialolith. The authors present the case of a 37-year-old female patient with edema of the submandibular area and a bulging sublingual caruncle due to a calculus that obstructed the salivary gland ostium.

ABSTRACT

A presença da metástase linfonodal é um fator limitante da sobrevida no câncer da boca. OBJETIVO: Avaliar as causas de falha no tratamento dos carcinomas de língua e soalho de boca em função do estadiamento. MÉTODO: Foram analisados 365 casos de carcinoma epidermoide de boca, tratados de 1978 a 2007, sendo 48 T1, 156 T2, 98 T3 e 63 T4, dos quais 193 foram pNo e 172 pN+. RESULTADOS: Entre os casos pN+, foram observados 17/46 recidivas (36,9%) nos casos não irradiados e 46/126 (36,5%) nos casos irradiados. Quanto aos resgates, nos casos pN0, obtivemos 16/51 (31,3%) e, nos pacientes pN+, de 3/77 (3,9%). CONCLUSÃO: O sucesso dos resgates é menor em pacientes com pN+, com maior recidiva local e menor sobrevida. .


The presence of metastatic nodes is a survival-limiting factor for patients with mouth tumors. OBJECTIVE: To evaluate the causes of treatment failure in carcinomas of the tongue and floor of the mouth due to staging. METHOD: This study included 365 patients with squamous cell carcinoma of the mouth treated from 1978 to 2007; 48 were staged as T1, 156 as T2, 98 as T3, and 63 as T4, of which 193 were pNo and 172 pN+. RESULTS: Among the pN+ cases, 17/46 (36.9%) of the patients not treated with radiation therapy had relapsing tumors, against 46/126 (36.5 %) of the patients who underwent radiation therapy. Success rates in the group of subjects submitted to salvage procedures were 16/51 (31.3%) for pN0 patients and 3/77 (3.9%) for pN+ patients. CONCLUSION: Salvage procedure success and survival rates are lower for pN+ patients; pN+ individuals also have more relapsing local disease. .

ABSTRACT

Tumor-associated macrophages (TAM) are the main cellular component in stroma of many tumors and participate in tumor angiogenesis. The aim of present study was to compare the microvascular density (MVD) and infiltrating macrophage density (IMD) in oral squamous cell carcinomas (OSCCs) with different histological grades. A histomorphometric analysis was performed after immunohistochemistry using antibodies such as von-Willebrand factor and CD68. A significant difference in MVD was found between well and moderately differentiated OSCCs (p<0.05). TAM were largely present in all studied tumors and the IMD was not different among OSCCs with different histological grades (p=0.381). Significant correlation between MVD and IMD was not observed (p=0.870). In conclusion, these results suggest that TAM and angiogenesis have an influence at different histological grades of OSCC. However, the lack of correlation between MVD and IMD could suggest that angiogenesis does not depend on the number of macrophages present in OSCC, but their predominant phenotype. Further studies involving distinct phenotypes of macrophages should be done to better understand the influence of TAM on the tumor angiogenesis.


Macrófagos associados a tumores (MAT) representam o componente principal do estroma de muitos tumores, além de participar da angiogênese tumoral. Este estudo comparou a microdensidade vascular (MDV) e densidade de macrófagos infiltrando o tumor (DMIT) em carcinoma escamocelular da boca (CEC) com diferentes graus histológicos de malignidade. Análise histomorfométrica foi empregada após técnica imuno-histoquímica para os anticorpos fator von-Willebrand e CD68. Uma diferença significante entre MDV e carcinomas bem e moderadamente diferenciados foi observada (p<0,05). MAT estavam fortemente presentes em todos os tumores estudados e a DMIT não foi diferente entre os diferentes graus histológicos de malignidade do CEC (p=0,381). Correlação significante entre MDV e DMIT não foi observada (p=0,870). Em conclusão, os resultados desse estudo sugerem a influência de MAT e angiogênese nos diferentes graus histológicos de malignidade do CEC. Entretanto, a ausência de correlação entre MDV e DMIT sugere que a angiogênese não depende do número de macrófagos presentes neste tipo de câncer, mas do fenótipo predominante. Outros estudos devem ser realizados a fim de contribuir para melhor compreensão da participação de MAT na angiogênese tumoral.

ABSTRACT

The aim of this study was to evaluate the immunoexpression of MMP-2, MMP-9 and CD31/microvascular density in squamous cell carcinomas of the floor of the mouth and to correlate the results with demographic, survival, clinical (TNM staging) and histopathological variables (tumor grade, perineural invasion, embolization and bone invasion). Data from medical records and diagnoses of 41 patients were reviewed. Histological sections were subjected to immunostaining using primary antibodies for human MMP-2, MMP-9 and CD31 and streptavidin-biotin-immunoperoxidase system. Histomorphometric analyses quantified positivity for MMPs (20 fields per slide, 100 points grade, ×200) and for CD31 (microvessels <50 µm in the area of the highest vascularization, 5 fields per slide, 100 points grade, ×400). Statistical design was composed by non-parametric Mann-Whitney U test (investigating the association between numerical variables and immunostainings), chi-square frequency test (in contingency tables), Fisher's exact test (when at least one expected frequency was less than 5 in 2×2 tables), Kaplan-Meier method (estimated probabilities of overall survival) and Iogrank test (comparison of survival curves), all with a significance level of 5%. There was a statistically significant correlation between immunostaining for MMP-2 and lymph node metastasis. Factors associated negatively with survival were N stage, histopathological grade, perineural invasion and immunostaining for MMP-9. There was no significant association between immunoexpression of CD31 and the other variables. The intensity of immunostaining for MMP-2 can be indicative of metastasis in lymph nodes and for MMP-9 of a lower probability of survival.


O objetivo deste estudo foi avaliar a imunoexpressão de MMP-2, MMP-9 e CD31/densidade microvascular em carcinomas espinocelulares de soalho bucal e correlacionar os resultados com variáveis demográficas, de sobrevida, clínicas (estadiamento TNM) e histopatológicas (grau de diferenciação tumoral, invasão perineural, embolização e invasão óssea). Dados de prontuários e de diagnósticos de 41 pacientes foram revisados. Cortes histológicos foram submetidos à imunomarcação usando anticorpos primários para MMP-2, MMP-9 e CD31 humanos e sistema streptoavidina-biotina-imunoperoxidase. Análise histomorfométrica quantificou a positividade para MMPs (20 campos, grade de 100 pontos por lâmina, ×200) e para CD31 (microvasos <50 µm na área de maior vascularização, 5 campos, grade de 100 pontos por lâmina, ×400). O planejamento estatístico foi composto pelo teste não paramétrico U de Mann-Whitney (verificação da associação entre variáveis numéricas e imunomarcações), teste de frequências do qui-quadrado (em tabelas de contingência), teste exato de Fisher (quando pelo menos uma frequência esperada foi menor do que 5 em tabelas 2×2), método de Kaplan-Meier (estimativa de probabilidades de sobrevida global) e teste de Iogrank (comparação das curvas de sobrevida), todos com nível de significância de 5%. Houve correlação estatisticamente significante entre imunomarcação para MMP-2 e metástase em linfonodo. Os fatores relacionados negativamente com a sobrevida foram estadiamento N, gradação histopatológica, invasão perineural e imunomarcação de MMP-9. Não houve associação significativa entre imunoexpressão de CD31 e as demais variáveis. A intensidade de imunomarcação para MMP-2 pode ser indicativa de metástase em linfonodo e para MMP-9 de uma menor probabilidade de sobrevida.

ABSTRACT

Lipomas are adipose mesenchymal neoplasms, they are relatively uncommon in the oral cavity, representing about 0.5% to 5% of all benign oral tumors1. The clinical presentation is typically as an asymptomatic yellowish mass. The overlying epithelium is intact, and superficial blood vessels are usually evident over the tumour. We report a case with an unusual and atypical presentation of the lipomas in the floor of mouth, which is quite a rare site in the literature even in the oral cavity lipomas.

ABSTRACT

A presença de linfonodos metastáticos é aspecto relevante no prognóstico do câncer bucal. OBJETIVO: Avaliar a densidade do linfonodo metastático (pN+) em pacientes com carcinoma espinocelular (CEC) de língua e soalho bucal e sua relação com a sobrevida livre de doença (SLD). MÉTODOS: De 1985 a 2007, 182 pacientes foram avaliados, dos quais 169 eram homens, sendo cinco estádio I, 35 estádio II, 56 estádio III e 85 estádio IV. A densidade do linfonodo foi mensurada por meio de sua mediana e a SLD pelo método de Kaplan-Meier e a diferença de grupo pelo teste log-rank. RESULTADOS:Após média de dissecção de 3,2 linfonodos metastáticos com pacientes, a densidade variou de 0,009 a 0,4, com média 0,09. A SLD a 5 anos foi de 44% e 28% para grupos com densidade linfonodal abaixo e acima da mediana (p = 0,006). O controle loco-regional a 2 anos foi de 71% e 49% para os casos com densidade abaixo e acima da mediana (p = 0,01). Quanto ao estádio pN, o controle loco-regional foi de 70% e 54% para os casos pN1 e pN2, sem significância estatística (0,20%). CONCLUSÃO: A densidade linfonodal pode ser utilizada como indicador prognóstico no CEC de língua e soalho bucal.


The presence of metastatic lymph nodes is a relevant prognostic factor in oral cancer. OBJECTIVE: This paper aims to assess metastatic lymph node density (pN+) in patients with tongue and floor-of-mouth squamous cell carcinoma (SCC) and the association of this parameter with disease-free survival (DFS). MATERIALS AND METHODS: A group of 182 patients seen between 1985 and 2007 was included, 169 of which were males. Five were on stage I, 35 on stage II, 56 on stage III, and 85 on stage IV. Median values were considered in lymph node density assessment, and the Kaplan-Meier curve was used to evaluate DFS; survival differences within the group were elicited through the log-rank test. RESULTS: An average 3.2 metastatic lymph nodes were excised from the patients in the group. Density ranged from 0.009 to 0.4, with a mean value of 0.09. Five-year DFS rates were of 44% and 28% for the groups with lymph node densities below and above the median respectively (p = 0.006). Two-year local/regional control was achieved for 71% and 49% for the patients below and above the median density respectively (p = 0.01). In terms of pN staging, local/regional control was achieved in 70% and 54% of pN1 and pN2 patients respectively, albeit without statistical significance (0.20%). CONCLUSION: Lymph node density may be used as a prognostic indicator for tongue and floor-of-mouth SCC.

ABSTRACT

Background: Nucleolar organizer regions (NOR) are associated with proliferative activity and represent a diagnostic and prognostic marker. Materials and Methods: Smears were taken from smokers, tobacco chewers, oral squamous cell carcinoma patients, and normal subjects and evaluated by 2 silver-staining nucleolar organizer region (AgNOR) counting methods: (1) mean number of AgNORs per nucleus (mAgNOR); and (2) percentage of nuclei with >3 and >5 AgNORs (pAgNOR). Results: A statistically significant difference was observed between normal subjects, smokers, tobacco chewers, and oral cancer patients and between tobacco chewers with and without lesion. No significant difference was observed between tobacco chewers and smokers except in the percentage of >5 criteria. Conclusions: AgNOR enumeration using noninvasive methods, such as the cytobrush appears to be useful technique in distinguishing between normal mucosa, mucosa with and without lesions exposed to carcinogens, such as tobacco and frank oral carcinoma.

ABSTRACT

Colorectal cancers have potential for lymphatic and hematogenous metastases. Surgery is the definitive treatment, but the prognosis can be improved with the addition of chemotherapy, radiotherapy or both. However, the incidence of recurrence, both local and distant, remains significant. Distant metastases occur most often in the liver and lung; however, metastases to bone, adrenals, lymph nodes, brain, skin and the oral region have been reported. Metastases to the oral region are uncommon and may occur in the oral soft tissues or jaw bones. The prognosis in such patients is usually very poor. We report a case of colorectal carcinoma with metastasis to the floor of the mouth. This is probably the first reported case of metastasis to the floor of the mouth in a patient with colorectal cancer

ABSTRACT

El quiste dermoide representa menos del 0,01 por ciento de todos los quistes de la cavidad bucal. Su ubicación más frecuente es en suelo de boca. Se presenta el caso de una paciente femenina de 19 años de edad que hacía aproximadamente 7 años había notado un aumento de volumen debajo de la lengua, el cual le crecía paulatinamente y ya se apreciaba por fuera de la cara. Además, le ocasionaba molestias al hablar y al masticar. Se realizaron estudios complementarios y bajo anestesia general nasotraqueal. Se procedió a su exéresis quirúrgica mediante un abordaje intrabucal, donde se obtuvieron excelentes resultados estéticos y funcionales. El diagnóstico histopatológico se correspondió con un quiste dermoide de suelo de boca. La paciente no ha tenido recurrencia de la lesión transcurridos tres años de la operación. El quiste dermoide de suelo de boca se presenta como una tumoración benigna de la línea media. La exéresis intrabucal demuestra beneficios estéticos y funcionales(AU)


The Dermoid cyst account for the 0.01 percent of all cysts of buccal cavity. Its more frequent location is in the mouth floor. This is the case of a female patient aged 19 who approximately 7 years noted an increase of volume under tongue growing gradually and noting outside face and the discomfort at to speak and to chew. Complementary studies were conducted and under general anesthesia a surgical exeresis was carried out by intrabuccal approach achieving excellent esthetic and functional results. Histopathologic diagnosis matched with a dermoid cyst of mouth floor. Patient has not lesion recurrence after three years after operation. We conclude that the Dermoid cyst of mouth floor appear as benign tumor of middle line. The intrabuccal exeresis demonstrates esthetic and functional benefits(AU)
