ABSTRACT
Cette étude rétrospective a porté sur les ostéomes, sur une durée de quatre ans au CHU de Yaoundé. En tenant compte des données cliniques et des comptes rendus opératoires, les patients dont les dossiers jugés satisfaisants pour remplir les critères d'inclusions ont été retenus.Il est apparu que les ostéomes sont peu fréquents dans notre contexte puisqu'ils ne représentent que 12,6 % des tumeurs osseuses. Ils se développent lentement et sans douleurs aux maxillaires comme à la mandibule. Cependant ils se localisent préférentiellement aux maxillaires. Ces ostéomes sont plus fréquents chez la femme et touchent surtout les adultes jeunes. Les diagnostics cliniques, radiologiques et histologiques sont assez aisés, permettant de classer les ostéomes en exostose et en énostose (endostose) selon qu'ils ont une évolution extra ou endosseuse. Le traitement est uniquement chirurgical et ne donne pas lieu aux récidives

El osteoma es una neoplasia benigna poco común, que se caracteriza por presentar un crecimiento óseo progresivo, el cual está compuesto por la proliferación bien diferenciada de hueso compacto y/o esponjoso. En el área maxilofacial se presenta con mayor frecuencia en la cara lingual posterior de la mandíbula. Se caracteriza por crecimiento lento y asintomático. El caso describe una paciente de 45 ños con un osteoma gigante mandibular de 4 años de evolución tratado quirúrgicamente.
Osteomas are considered a rare benign neoplasm, characterized by a progressive bone growth, which is composed of a proliferation well differentiated of compact or cancellous bone. In the maxillofacial area when present, commonly found in the posterior lingual surface of the mandible. It is characterized by slow growth and asymptomatic. The case describes a mandibular giant osteoma of 4 year of evolution treated with surgical treatment.

The authors present enhanced depth imaging optical coherence tomography (EDI OCT) and fundus autofluorescence (FAF) characteristics of a patient with bilateral choroidal osteoma and try to make a correlation between two imaging techniques. Two eyes of a patient with choroidal osteoma underwent complete ophthalmic examination. Enhanced depth imaging optical coherence tomography revealed a cage-like pattern, which corresponded to the calcified region of the tumor. Fundus autofluorescence imaging of the same area showed slight hyperautofluorescence. Three different reflectivity patterns in the decalcified area were defined. In the areas of subretinal fluid, outer segment elongations similar to central serous chorioretinopathy were observed. Hyperautofluorescent spots were evident in fundus autofluorescence in the same area. Calcified and decalcified portions of choroidal osteoma as well as the atrophy of choriocapillaris demonstrated different patterns with enhanced depth imaging and fundus autofluorescence imaging. Both techniques were found to be beneficial in the diagnosis and follow-up of choroidal osteoma.
Os autores apresentam tomografia de coerência óptica com profundidade de imagem aprimorada (EDI OCT) e autofluorescência de fundo (FAF) características de um paciente com osteoma de coroide bilateral e tentam correlacionar as duas técnicas de imagem. Dois olhos de um paciente com osteoma de coroide foram submetidos a exame oftalmológico completo. Tomografia de coerência óptica com profundidade de imagem aprimorada revelou padrão em gaiola, correspondente à região de calcificação do tumor. Imagens de autofluorescência de fundo da mesma área mostraram ligeira autofluorescência positiva. Três padrões de refletividade diferentes foram definidos na área descalcificada. Nas áreas com fluido sub-retiniano, foram observados prolongamentos dos segmentos externos semelhantes aos da coroidorretinopatia serosa central. Manchas autofluorescentes positivas foram evidentes em autofluorescência de fundo na mesma área. Porções calcificadas e descalcificadas do osteoma de coroide, bem como a atrofia da camada coriocapilar, demonstraram diferentes padrões de tomografia de coerência óptica com profundidade de imagem aprimorada e de imagens de autofluorescência de fundo. Ambas as técnicas se mostraram úteis no diagnóstico e acompanhamento de osteoma de coroide.

Introducción. El torus , o rodete, palatino es una alteración ósea benigna que puede generar molestias en la fonación y en la deglución. Cuando su crecimiento o exposición persistente producen síntomas molestos, debe ser resecado quirúrgicamente. Presentación del caso. Se trata de una paciente de 82 años de edad, que consultó por una lesión ulcerativa de un año de evolución, que producía dolor, halitosis y molestia a la deglución. En el examen físico de la cavidad oral, se observó una prominencia de consistencia dura en la línea media, con perforación y ulceración de la mucosa palatina en su porción lateral posterior izquierda. Se consideraron los diagnósticos de torus palatino, osteoma, granuloma piógeno y neoplasia de tejidos blandos. Se decidió resecarla quirúrgicamente y hacer el estudio histopatológico. La evolución clínica fue satisfactoria, con resolución completa un mes después de la cirugía. En el estudio de histopatología se observó hiperostosis ósea con inflamación crónica de los tejidos blandos e hiperplasia simple de la mucosa, que corresponden a un torus palatino. Discusión. Se reporta un inusual caso de exposición espontánea de un torus palatino que ocupaba casi toda la bóveda palatina, se describe su resección quirúrgica y se informan los hallazgos de histopatología. En la revisión bibliográfica realizada, no se encontró un reporte previo de exposición espontánea de torus palatino.
Introduction: Palatal torus, or torus palatinus, is a benign bone alteration that may cause some discomfort during phonation or swallowing. When its growth or persistent exposition produces unpleasant symptoms, it must be surgically removed. Case presentation: We treated an 82-year-old female patient who consulted for a painful ulcerous lesion she had had for a year and which produced halitosis and discomfort when swallowing. During the oral cavity physical exam we observed a hard protuberance on the midline. It showed a perforation and ulceration of the lateral posterior palatal mucosa on the left side. We considered the following diagnosis: palatal torus, osteoma, pyogenic granuloma, or a soft-tissue neoplasia. We decided to surgically remove it and to perform a histopathological examination. Clinical evolution was satisfactory with complete resolution one month after surgery. The histopathological examination showed hyperostosis along with chronic inflammation of the soft tissues and a simple hyperplasia of the mucosa, which in turn indicated a palatal torus. Discussion: We report an unusual case of spontaneous exposition of a palatal torus which took up almost all of the hard palate area. Its resection is described and we inform the histopathological findings. In the literature review, we did not find a previous report of a spontaneous exposition of a palatal torus.

Choroidal osteoma is an unusual form of intraocular calcification seen in otherwise healthy eyes. It is a benign idiopathic osseous tumor of the choroid, typically seen in young females. Choroidal neovascular membrane (CNVM) is a complication seen in one-third of these patients and carries a poor visual outcome. We report a case of a 25-year-old hyperthyroid female with choroidal osteoma and subfoveal CNVM in her left eye which was successfully treated using low-fluence photodynamic therapy (PDT) with verteporfin followed by a single injection of intravitreal ranibizumab.

Osteoma cutis é a formação óssea no interior da pele, podendo ser primária ou secundária. Única ou múltipla, de tamanhos variados e acometendo ambos os sexos, é uma lesão cutânea rara, de etiopatogenia e classificação ainda discutidas. Nosso objetivo foi relatar o diagnóstico e a terapêutica minimamente invasiva de lesões múltiplas de osteoma cutis na face em pacientes com sequelas de acne. Fizemos a retirada dos osteomas com agulhas BD 0,70 x 25 22G1, sem anestésicos tópicos ou injetáveis no local. As pequenas incisões foram deixadas expostas, com pomada cicatrizante. Obteve-se um excelente resultado estético em 15 dias.
Osteoma cutis is a bone formation in the dermis can to be primary or secondary forms. Only, multiples, many forms, occurring on either sex, they are a rare cutaneous disease. The pathogenesis and classification remains unclear. Our objective was the diagnostic and small invasive surgery treatment of the osteoma cutis multiple of the face, in patients as a sequel of acne. To remove the osteoma we used needle BD 0,70x25 22G1, without anesthetic topic or inject able site. The small wounds were exposed with scarring balsam. We got an excellent esthetic result after 15 days.

A 56-year old woman presented with headaches and nasal congestion secondary to bilateral ethmoid osteomas and she made a full recovery following endoscopic resection. Paranasal osteomas are common, benign, encapsulated tumours that are often asymptomatic, but may present similarly to rhinosinusitis and occasionally cause complications depending on their anatomical location. Bilateral ethmoidal osteomas, however, are a rare occurrence and have not been previously reported in the English literature as far as the authors are aware. Ethmoidal and fronto-ethmoidal osteomas, like other paranasal osteomas, are easily diagnosed using computed tomography and are increasingly amenable to endoscopic resection. An evidence-based management plan is presented.
Una mujer de 56 años se presentó con los dolores de cabeza y congestión nasal secundaria a un osteoma etmoidal bilateral, tras su recuperación total a partir de una resección endoscópica. Los osteomas paranasales son tumores comunes, benignos, y encapsulados, a menudo asintomáticos, pero que pueden presentarse de modo similar a la rinosinusitis, y ocasionalmente causar complicaciones, en dependencia de su localización anatómica. Los osteomas etmoidales bilaterales, sin embargo, son una ocurrencia rara y hasta donde sabemos, no ha sido reportado con anterioridad en la literatura en inglés. Los osteomas etmoidales y fronto-etmoidales - al igual que otros osteomas paranasales - se diagnostican fácilmente usando CT, y son cada vez más tratables mediante resección endoscópica. Se presenta un plan de tratamiento basado en la evidencia.

Introdução/Objetivo: Osteoma da mastoide é um tumor osteogênico benigno, considerado raro nesta localização. Até o ano de 2006 havia cerca de 150 casos relatados na literatura médica. Na sua etiopatogenia incluem fatores relacionados com a embriogênese, metaplasia, trauma e inflamação. Geralmente são assintomáticos e manifestam-se através de tumoração protruindo da região retroauricular. Tomografia computadorizada tem sido útil no seu diagnóstico e planejamento cirúrgico. Seu resultado cirúrgico é bom do ponto de vista estético e curativo. Método: Foram estudados dois casos de osteoma mastoideo e analisados quanto ao seu quadro clínico, exames de imagens, tratamento e resultados. Resultados: Ambos localizados na região mastoidea direita. Ausência de história de trauma prévio nesta região. Exame neurológico normal. Tomografia computadorizada craniana revelou lesão hiperdensa envolvendo a córtex do osso temporal na região mastoidea, compatível radiologicamente com osteoma. Foram submetidos à exérese total da lesão. Exame anatomo-patológico: Osteoma. Apresentaram resultados estéticos e curativos excelente. Não houve recidiva ou transformação maligna. Conclusões: O osteoma localizado na região mastoidea é um tumor benigno raro. Provoca deformidade estética local. Geralmente é assintomático. O exame de eleição é a tomografia computadorizada. Apresenta diagnóstico diferencial com hemangioma, displasia fibrosa, osteosarcoma e metástase osteoblástica. Não apresenta transformação maligna. Seu tratamento é cirúrgico e com resultados estéticos e curativos excelente.
Introduction/Objective: The mastoid osteoma is a benign osteogenic tumor, considered to be uncommon in such location. By 2006, there were about 150 cases reported in the medical literature. Its etiopathogenesis includes factors relating to embryogenesis, metaplasia, trauma and inflammation. They are generally asymptomatic and appear through tumoration protrusion from the retroauricular region. Computed tomography has been useful for its diagnosis and surgical planning. Its surgical results are good from a aesthetic and curative point of view. Method: We studied two cases of mastoid osteoma and analyzed them as for their clinical state, imaging exams, treatment and results. Results: Both locating in the right mastoid region. Absence of a previous trauma in this region. Normal neurological exam. The cranial computed tomography revealed a hyperdense lesion involving the cortex of the temporal bone in the mastoid region, radiologically compatible with osteoma. They were submitted to complete exeresis of the lesion. Anatomopathological exam: osteoma. They had excellent aesthetic and curative results. There was no recurrence or malignant transformation. Conclusions: The osteoma located in the mastoid region is an uncommon benign tumor. It provokes local aesthetic deformity and is generally asymptomatic. The choice exam is computed tomography. It has a differential diagnosis with hemangioma, fibrous dysplasia, osteosarcoma and osteoblastic metastasis. The exam does not present malignant transformation. The treatment is surgical and with excellent aesthetic and curative results.

A raíz de un caso de osteoma de coroides que se diagnóstico en el Instituto Barraquer de Barcelona se hizo una revisión bibliográfica del tema y se revisaron las fichas con el diagnóstico de osteoma de coroides entre los años 1982 y 2004, encontrándose 29 casos diagnosticados como tal. La revisión de las fichas descartó a 13 pacientes que no cumplían con los parámetros para osteomas, ya sea por mala interpretación de la ecografía o de otros exámenes. Los 16 restantes, 9 habían concurrido a una segunda opinión ya con el diagnóstico de osteoma. Los exámenes hechos en nuestro centro corroboraron el diagnóstico. Cinco pacientes nos consultaron por primera vez por disminución de la agudeza visual y en nuestro examen se encontró el osteoma. Otro caso nos consultó por jaqueca y diagnóstico previo en otro centro de coroiditis posterior. Un caso fue un hallazgo casual en una ecografía practicada por nosotros.

Os autores apresentam um caso de osteoma de coróide diagnosticado em paciente do sexo masculino aos 62 anos de idade. A lesão bem delimitada e pouco elevada no pólo posterior do olho direito acompanhada de vascularização interna e neovascularização de coróide em sua borda temporal superior e inferior levaram à suspeita do tumor. O diagnóstico de certeza foi obtido com ecografia A e B e tomografia computadorizada. A tomografia de coerência óptica mostrou alta refletividade em toda a espessura do osteoma bem como elevação do complexo EPR-cório-capilar na região da membrana neovascular subretiniana. Embora os achados tomográficos descritos na literatura e os observados neste caso sejam variados, a tomografia de coerência óptica pode colaborar no diagnóstico de osteoma de coróide.

No estudo, descreveu-se uma imagem sugestiva de osteoma na região do seio maxilar esquerdo por meio de CT. Após exame radiográfico de rotina, foi indicado ao paciente um CT de alta resolução para visibilizar uma massa radiopaca, a qual foi avaliada segundo o índice de Misch, bem como analisada em seus maiores longos eixos. Não foi descartada a hipótese de outras patologias, como o osteoma osteóide. Entretanto, os quesitos estudados através do CT, juntamente com dados clínicos, possibilitaram obter um diagnóstico quase conclusivo. Deste modo, ressalta-se a importância da tomografia computadorizada de alta resolução como um dos meios complementares para determinar o diagnóstico definitivo que será confirmado após exame histopatológico

BACKGROUND: Choroidal osteoma is a rare tumour of the choroid. This is the first report of cases of choroidal osteoma in Thai patients. OBJECTIVE: To report the clinical characteristics, imaging findings and long-term follow-up of choroidal osteoma in four Oriental patients. METHOD: Four cases of choroidal osteoma were observed for 5 years or more. RESULTS: All patients were young female patients whose ages ranged from 24 to 37 years. Three were unilateral and one was bilateral. The tumors were located at the juxtapapillary and macular area with overlying serous retinal detachment. Two patients had previous thyroid diseases and one was pregnant when the tumors were diagnosed. Osteoma did not develop in the vicinity of posterior staphyloma of high myopic eyes. Echography showed acoustic features of a plano-convex sonically dense lesion with high reflectivity echoes which persisted despite lower system sensitivity. None had subretinal neovascularization. Subretinal fluid disappeared spontaneously within one to 14 months in three patients. Gradual growth of the tumor in a pseudopodium manner developed from two to six years after initial examination. Decalcification occurred spontaneously or after laser ablation. CONCLUSIONS: The authors presented four Oriental patients with choroidal osteoma who were observed for at least 5 years. Echography is the best method for identifying this lesion and has unique acoustic features. Subretinal fluid can be seen in the absence of subretinal neovascularization and resorbs spontaneously. Decalcification occurred as a natural process or after laser ablative treatment. Hormonal changes may implicate the development of this tumor.

Os autores relatam os achados da vídeo-angiografia digital pela indocianina verde no diagnóstico diferencial de tumores da coróide. Foram estudados 13 casos: 3 hemangiomas, 4 osteomas, 3 carcinomas metastásicos e 3 melanomas malignos. Foram reconhecidas características angiográficas próprias e constantes capazes de identificar hemangiomas, osteomas e carcinomas metastásticos diferenciando-se entre si e eles dos tumores pigmentados, principalmente o melanoma maligno. No entanto, tais características angiográficas pela indocianina verde isoladas, näo mostram significado diagnóstico inequívoco em tumores pigmentados da coróide. Baseados nestas observaçöes, concluiu-se que o uso da indocianina verde em tumores da coróide, reserva esta nova técnica de exame, importância diagnóstica complementar, com limitaçöes, no contexto do diagnóstico diferencial dos tumores da coróide
