ABSTRACT

RESUMEN Se presentó el caso de una paciente femenina de 40 años de edad que acudió a consulta por presentar aumento de volumen en la región parotídea izquierda. Se realizó ortopantomografía, radiografías simples anteroposterior y lateral de cráneo que revelaron la presencia de una imagen radiolúcida en la región lateral de la rama mandibular izquierda. El diagnóstico clínico fue de osteoma periférico a este nivel, por lo que se realizó remoción quirúrgica total de la lesión. La biopsia confirmó el diagnóstico de osteoma ebúrneo periférico. El osteoma es una neoplasia benigna de tejido óseo, poco frecuente y, rara vez, se localiza de manera aislada en la mandíbula. No se diagnosticaron complicaciones posoperatorias y la paciente mostró satisfacción con la atención estomatológica brindada.


ABSTRACT A 40-year-old female patient came to the consultation due to an increase in volume in the left parotid region. Orthopantomography and simple anteroposterior and lateral skull radiographies were performed, revealing the presence of a radiolucent image in the lateral region of the left mandibular side. The clinical diagnosis at this point was of peripheral osteoma, for which a total surgical removal of the lesion was performed. The biopsy confirmed the diagnosis of peripheral osteoma. An osteoma is a rare benign neoplasm of bone tissue, and is rarely found isolated in the mandible. Postoperative complications were not diagnosed and the patient was satisfied with the dental care provided.


RESUMO Foi apresentado o caso de uma paciente do sexo feminino, 40 anos de idade, que compareceu à consulta por aumento de volume na região da parótida esquerda. Foram realizadas ortopantomografia, radiografias simples ântero-posterior e lateral do crânio, que revelaram a presença de imagem radiotransparente na região lateral do ramo mandibular esquerdo. O diagnóstico clínico foi de osteoma periférico a este nível, para o qual foi realizada a remoção cirúrgica total da lesão. A biópsia confirmou o diagnóstico de osteoma periférico ebúrneo. O osteoma é uma neoplasia benigna do tecido ósseo, pouco frequente e raramente localizada de forma isolada na mandíbula. Complicações pós-operatórias não foram diagnosticadas e o paciente ficou satisfeito com o atendimento odontológico prestado.

ABSTRACT

Los tumores de cavidades paranasales presentan una baja frecuencia. Dentro de éstos, entre los benignos destacan las lesiones fibroóseas que se caracterizan por el reemplazo de hueso normal por estroma celular fibroso. Dentro de estas lesiones se describen osteoma, displasia fibrosa y fibroma osificante. Se revisan 3 casos de pacientes del Hospital Clínico de la Universidad de Chile y se presenta una revisión bibliográfica en cuanto a las lesiones fibroóseas, su clínica, diagnóstico, imagenología y tratamiento.


The tumors of paranasal cavities present a low frequency. Among the benign tumors are fibro-osseous lesions characterized by the replacement of normal bone by fibrous cell stroma. Osteoma, fibrous dysplasia, and ossifying fibroma are described within these lesions. Three cases of patients from the Hospital Clínico de la Universidad de Chile are reviewed and a bibliographic review is presented regarding the fibro-osseous lesions, their clinical features, diagnosis, imaging and treatment.

ABSTRACT

Abstract Osteoma is a benign osteogenic neoplasm originating from the continuous proliferation of compact and/or cancellous mature bone. The tumor can be classified as peripheral, central or extra-skeletal regarding location and it commonly seen in the cranio-facial region especially at the skull and paranasal sinuses. The exact etiology of the tumor is still controversial; however, it is considered that infection, trauma, muscle activity contributes the occurrence of the tumor. Due to the slow growing nature of osteoma, it is coincidentally detected on radiographs or when the tumor reaches a large size enough to trigger symptoms and cause facial disfigurement. Although mainly detected in the craniofacial bones, osteomas are rarely located in the jaw bones. The purpose of this review, is to present the diagnosis and treatment plan of a peripheral osteoma in the mandibular angulus region of an 8-year-old boy together with a review of published cases of peripheral osteomas of mandibular angulus.


Resumen El osteoma es una neoplasia osteogénica benigna que se origina de la proliferación continua de hueso maduro compacto y/o esponjoso. El tumor se puede clasificar como periférico, central o extraesquelético con respecto a la ubicación y se ve comúnmente en la región craneofacial, especialmente en el cráneo y los senos paranasales. La etiología exacta del tumor sigue siendo controvertida; sin embargo, se considera que la infección, el trauma y la actividad muscular contribuyen a la aparición del tumor. Debido a la naturaleza de crecimiento lento del osteoma, se detecta casualmente en las radiografías o cuando el tumor alcanza un tamaño grande lo suficiente como para desencadenar síntomas y causar desfiguración facial. Aunque se detecta principalmente en los huesos craneofaciales, los osteomas rara vez se localizan en los huesos de la mandíbula. El objetivo de esta revisión es presentar el diagnóstico y el plan de tratamiento de un osteoma periférico en la región angular mandibular de un niño de 8 años junto con una revisión de casos publicados de osteomas periféricos de angulación mandibular.

ABSTRACT

Abstract Introduction Osteomas of the paranasal sinuses are benign bone tumours that produce clinical signs depending on their size and location. In most reported cases large tumours are excised by an external approach or in conjunction with an endoscopic technique. Endoscopic treatment of such tumours is a huge challenge for the operator. Objective Determine the optimal surgical approach by analysing giant osteomas of the frontal and ethmoidal sinuses in the literature. Methods Group of 37 osteomas obtained from the literature review. A group of osteomas removed only by endoscopy was compared with a group in which an external approach (lateral rhynotomy or craniotomy) or combined external and endoscopic approach was applied. Results The authors, based on the statistical analysis of the literature data, have found that the average size of osteomas excised endoscopically and those removed by external approaches does not differ statistically, when the osteomas are located in the ethmoidal cells (p = 0.2691) and the frontal sinuses (p = 0.5891). Conclusion The choice of surgical method appears to be independent of the osteoma size and the decision is likely to be taken based on the experience of the surgeon, available equipment and knowledge of different surgical techniques.


Resumo Introdução Osteomas dos seios paranasais são tumores ósseos benignos cujas manifestações clínicas ocorrem em função de seu tamanho e localização. Na maioria dos casos relatados os tumores grandes são excisados por uma abordagem externa ou associada a uma técnica endoscópica. O tratamento endoscópico destes tumores ainda é um grande desafio para o cirurgião. Objetivo Determinar a abordagem cirúrgica ideal ao analisar osteomas gigantes dos seios frontal e etmoidal na literatura. Método Um total de 38 osteomas foram avaliados a partir da revisão da literatura. Um grupo de osteomas removidos apenas por cirurgia endoscópica foi comparado com um grupo para o qual foi utilizado uma abordagem externa (rinotomia lateral ou craniotomia) ou uma abordagem combinada, externa e endoscópica. Resultados Os autores, com base na análise estatística dos dados da literatura, observaram que o tamanho médio dos osteomas excisados endoscopicamente e daqueles que foram removidos através de uma abordagem externa não diferiram estatisticamente, tanto para osteomas localizados no seio etmoidal (p = 0.2691) quanto para os localizados no seio frontal (p = 0.5891). Conclusão A escolha do método cirúrgico parece ser independente do tamanho do osteoma e a decisão provavelmente será tomada com base na experiência prévia do cirurgião, nos equipamentos disponíveis e conhecimento de diferentes técnicas cirúrgicas.

ABSTRACT

El osteoma es el tumor más frecuente de los senos paranasales, habitualmente asintomático debido a su lento crecimiento, sin embargo, pueden desarrollarse síntomas dependiendo del tamaño, localización y extensión, con potencial compromiso de órbita y cerebro. La cirugía está indicada en casos sintomáticos pudiendo realizarse abordaje externo, endoscópico o combinado. Presentamos un caso de osteoma etmoidal con compromiso orbitario resuelto, manejado por medio de la cirugía endoscópica nasal, con apoyo de navegación.


The osteoma is the most common tumor of the paranasal sinuses, is usually asymptomatic because of their slow growth, however, may develop symptoms depending on the size, location and extent, with potential compromise of orbit and brain. Surgery is indicated in symptomatic cases, with external, endoscopic or combined approach. We present a case of ethmoidal osteoma with orbital involvement managed by endoscopic image guided surgery.

ABSTRACT

ABSTRACT We report enhanced depth imaging optical coherence tomography (EDI-OCT) features based on clinical and imaging data from two newly diagnosed cases of choroidal osteoma presenting with recent visual loss secondary to choroidal neovascular membranes. The features described in the two cases, compression of the choriocapillaris and disorganization of the medium and large vessel layers, are consistent with those of previous reports. We noticed a sponge-like pattern previously reported, but it was subtle. Both lesions had multiple intralesional layers and a typical intrinsic transparency with visibility of the sclerochoroidal junction.


RESUMO Relatamos as características na tomografia computadorizada óptica (EDI-OCT) de 2 pacientes recém diagnosticados com osteoma de coroide apresentando perda visual secundária à membranas neovasculares coroideanas. As características descritas em nossos 2 casos foram consistentes com trabalhos anteriores, exibindo a compressão da coriocapilar e desorganização das camadas médias e de grandes vasos. Notamos também o padrão em esponja anteriormente descrito, porém de forma discreta. Ambas as lesões tinham várias camadas intralesionais e uma transparência intrínseca típica com visibilidade da junção da esclero-coroideana.

ABSTRACT

El osteoma cutis (OC) es una lesión compuesta de tejido óseo en dermis y/o hipodermis. Se clasifican en primarios, cuando se desarrollan en piel sana, y secundarios, cuando aparecen sobre lesiones preexistentes. Mujer de 61 años con antecedente de linfoma de Hodgkin en remisión, presentó una lesión de larga data, desarrollada en piel sana, en primer dedo de la mano izquierda, que cursaba con brotes recurrentes y autolimitados de dolor y aumento de temperatura local. La exploración física mostró un nódulo pétreo, con úlcera de fondo calcáreo. El estudio histopatológico de la biopsia escisional reveló tejido óseo, sin otras lesiones cutáneas asociadas. El estudio complementario, incluyendo hemograma, función renal y hepática, calcio y fósforo séricos, PTH, TSH, vitamina D y calciuria fue normal. Descartándose alteraciones en el metabolismo calcio-fosforo y otras lesiones cutáneas preexistentes, se realizó el diagnostico de OC primario en forma de placa. El OC es una lesión benigna, pudiendo ser primario o secundario. Los secundarios representan cerca del 85% y se originan por la osificación de lesiones preexistentes tumorales o inflamatorias. Los OC primarios se presentan aislados o formando parte de síndromes como la fibrodisplasia osificante progresiva, la osteodistrofia hereditaria de Albright y la heteroplasia osificante progresiva. A pesar de la asociación a mutaciones en GNAS de OC y estos síndromes, el diagnóstico de ambos es fundamentalmente clínico. Los OC primarios sin síndrome asociado, se dividen en osteomas miliares de la cara y osteomas en forma de placa (plate-like OC), como este caso. Ante un OC primario, debemos descartar síndromes asociados a osificaciones heterotópicas.


Osteoma cutis (OC) is a lesion composed of bone tissue located in the dermis and/or hypodermis. It is classified as primary when it develops over healthy skin; and secondary when it develops over preexisting lesions. A 61-year-old woman with history of Hodgkin lymphoma in remission, presents a longstanding lesion located on the first finger of her left hand which developed over healthy skin, associated with recurrent and self-limited episodes of pain and increased local temperature. Physical examination reveals a stone-hard nodule, with a calcareous-bottomed ulcer. The histopathological evaluation of the excisional biopsy revealed bone tissue. Complementary studies included: complete blood count, renal and hepatic function, plasma calcium and phosphorus, PTH, TSH, vitamin D, and urinary calcium, all of them in normal ranges. Once systemic disease was ruled out, platelike OC was diagnosed. OC is a benign lesion which can be primary or secondary. Secondary OC represent nearly 85% of cases, and it corresponds to an ossification of preexisting tumoral or inflammatory lesions. Primary OC is less frequent, it appears isolated or as part of syndromes like fibrodysplasia ossificans progressiva, Albright hereditary osteodystrophy, and progressive osseous heteroplasia. GNAS mutations have been described in primary OC as in these syndromes, but the final diagnosis relies on the clinical picture. Isolated primary OC is classified in milliary osteomas of the face and plate-like OC, like our case. When facing primary OC, syndromes that present with heterotopic ossification must be ruled out.
