ABSTRACT

Central ossifying fi broma is a bony tumor, which is believed to be derived from the cells of the periodontal ligament. Central ossifying fi broma behaves like, a benign bone neoplasm. Th is bone tumor consists of highly cellular, fi brous tissue that contains varying amounts of calcifi ed tissue resembling bone, cementum, or both. Central ossifying fi bromas of the mandible are common; however, they are rare in the maxillary region however they are common in the mandible, have got a female predeliction and is usually seen in the age between 35 and 40 years of age. In this report, we have described a 35-year-old female with minimal clinical symptoms diagnosed as central ossifying fi broma in the anterior maxillary region.

ABSTRACT

El objetivo de este estudio fue determinar la frecuencia relativa y distribución de lesiones reaccionales hiperplásicas (LRH) de la mucosa oral, presentes en el registro de biopsias del Servicio de Anatomía Patológica de la Facultad de Odontología, Universidad de Chile. Este estudio de tipo retrospectivo consistió en 1149 biopsias con diagnóstico histopatológico de LRH, entre los años 2000-2011. Las LRH se clasificaron en 5 grupos: Hiperplasia fibrosa (HF), granuloma piogénico (GP), granuloma periférico de células gigantes (GPCG) y fibroma osificante periférico(FOP). Los datos de edad y sexo de los sujetos, y de localización y tipo de lesión, fueron obtenidos del registro de biopsias de cada caso. De las LRH, la lesión más frecuente fue HF (71,1 por ciento), seguido de GP (21,1 por ciento), GPCG (5 por ciento) y FOP (2,9 por ciento) respectivamente. Las biopsias de LRH fueron mas frecuentes en mujeres (70,7 por ciento). El rango etario más afectado fue el de 50 a 59 años (22 por ciento). La localización de mayor frecuencia de LRH fue el maxilar superior (24,7 por ciento), seguida de mejilla (20,6 por ciento), lengua (19,4 por ciento), mandíbula (18,5 por ciento), labio inferior (9,9 por ciento) y labio superior (6,7 por ciento). En este estudio, de las LRH el diagnóstico más prevalente fue FH. El sexo más afectado fue el femenino, el rango etario el de 50 a 59 años y la ubicación más frecuente, maxilar superior. Estos resultados en general son concordantes con lo descrito en otros países.


The aim of this study was to determine the relative frequency and distribution of reactive hyperplastic lesions (RHL) of the oral mucosa at the Oral Pathology Institute of the School of Dentistry at the University of Chile. This was a retrospective study of 1149 biopsies with histopathological diagnosis of RHL, performed between 2000 and 2011. The RHL were classified in 4 groups: fibrous hyperplasia (FH), pyogenic granuloma (PG), peripheral giant-cell granuloma (PGCG) and peripheral ossifying fibroma (POF). Results: the most frequent RHL was FH (71. 1%), followed by PG (21.1%), PGCG (5 %) and POF (2.9%). RHLs were more frequent in women (70.7%). The most highly affected age group was the 50- to 59-year-olds (22%). The most frequent location for RHL was maxilla (24.7%), followed by cheek (20.6%), tongue (19.4%) and jaw (18.5%). The most prevalent RHL diagnosis was FH. Themost frequently affected sex was female, the most frequent agerange was 50-59 years, and the most frequent location, maxilla.

ABSTRACT

Adenomatoid odontogenic tumor (AOT) is an uncommon, benign and slow growing odontogenic tumor, which is usually located in an anterior region of the maxilla without pain. Cemento-ossifying fibroma (COF) is a relatively rare benign tumor of the jaw. Here we present 2 lesions presenting in unusual forms, follicular variant of AOT in the mandible and COF associated with impacted canine in the mandible, occurring concomitantly in the same patient. Both lesions presented classic histopathologic features.

ABSTRACT

Este artigo aborda 18 casos de fibroma ossificante periférico (FOP) diagnosticados no Centro de Referência de Lesões Bucais da Universidade Estadual de Feira de Santana/Bahia, no período de 2002 a 2008. Para descrever a relação entre as variáveis sociodemográficas com o FOP, utilizou-se o Statistical Package for Social Science (SPSS), versão 10.0 for Windows (1998). Observou-se maior acometimento desta doença na quarta década de vida, sexo feminino e cor não branca. A gengiva superior anterior foi a região de maior prevalência. Faz-se importante que os cirurgiões-dentistas conheçam as características do FOP para o correto diagnóstico.

ABSTRACT

Foi realizado um estudo clínico retrospectivo descritivo e histoquímico de casos do fibroma ossificante periférico (FOP) e da lesão de células gigantes periférica (LCGP), coletados aleatoriamente no arquivo do Serviço de Diagnóstico Histopatológico da Universidade de Passo Fundo. O objetivo do trabalho foi comparar as atividades proliferativas celulares dessas lesões, visando o estabelecimento de uma conduta terapêutica adequada para cada uma das enfermidades. Os dados referentes ao sexo, idade, raça, localização da lesão e ocorrência de recidiva foram analisados e, o número de regiões organizadoras nucleolares (NORs) por núcleo de células ovóides foi determinado por meio do método de impregnação pela prata (Ag-NOR). Os resultados obtidos para o FOP foram de prevalência da lesão em mulheres (70%) da raça branca (60%) com média de idade de 28,11 anos, maior ocorrência da lesão na maxila anterior e índice de recidiva de 30%. O número médio de NORs foi de 1,72 para cada núcleo. Já para a LCGP, o sexo feminino também atingiu 70%, porém a média de idade foi de 42,90 anos e 100% dos pacientes pertenciam à raça branca. A ocorrência da lesão foi maior na região mandibular anterior e apresentou um índice de 20% de recidiva. Nesta lesão, o número médio de NORs foi de 1,93 por núcleo. Contudo, nos testes de correlação, nenhuma das características clínicas apresentou associação com o número médio de NORs por núcleo e a comparação desse número médio por núcleo nas LCGPs e nos FOPs não mostrou diferença significativa entre os grupos.


A retrospective clinical descritive and histochemical study envolving cases of periferic bone fibroma and of periferic giant cell lesion, randomly collected from the archives of Histophatologic Diagnostic Service of University of Passo Fundo was made. The objective of this work was to compare the proliferating cellular activities of these lesions, aiming the establishment of an adequate therapeutic conduct to each one of the disorders. The datas referring to the gender, age, race, position of the lesion and recurrence occurrence were analized and considered and the NORs’ numbers by egg-shaped cells’ nucleus were analized through the impregnation of silver method (Ag-NOR), getting as a result of periferic bone fibroma, 70% women, with an age average of 28.11 years old, where 60% of the pacients were white, and with the lesion’s position more often being on the front upper jaw, with the recurrence’s index up to 30%. The NORs’ average number was of 1.72 to each nucleus. On the periphery giant cell lesion, the female gender had also achieved 70%, however the age’s average was of 42.90 and 100% were white. The occurrence of the lesion was higher on the front inferior jaw and had showed a recurrence’s index of 20%. The NORs’ average of this lesion was 1.93 to each nucleus. Nevertheless, on the correlation’s tests none of these clinic characteristics showed a connection with the higher average’s number of NORs by nucleus and the comparison of NORs average’s number by nucleus on periphery bone fibroma and periphery giant cell lesion did not show a significant difference between the groups.

ABSTRACT

Actualmente se define el fibroma cemento-osificante como una sola lesión, uniendo a las pre-existentes fibroma osificante y fibroma cementificante, ya que no se encuentran diferencias de comportamiento y de origen entre ellas. Se revisaron los casos diagnósticados como fibromas osificantes, fibroma cementificante y fibroma cemento-osificante del Instituto de Referencia de Patología Oral de la Facultad de Odontología, Unniversidad de Chile, para determinar sus características clínicas, obteniéndose una muestra de 91 casos. Se observó mayor frecuencia en mujeres de la 4ta. década de vida, siendo el maxilar inferior la zona más afectada. Las características clínicas se resumen como una lesión con aumento de volumen de crecimiento lento, asintomático y con porcentaje de recidiva. Radiográficamente lo más frecuente es encontrar una lesión de densidad radiopaca con límites netos.
