ABSTRACT

ABSTRACT The epidermal cyst is a rare, benign lesion, usually asymptomatic and slowly enlarging, more frequently located in the submandibular region. Its etiology is believed to be associated with the epithelial residual tissues retained in the midline during the closure of the first and second brachial arches, in the third and fourth weeks of intra-uterine life. Its clinical characteristics are of a rubbery consistency to palpation, well defined borders, with the absence of skin appendages within their squamous epithelium lined walls. The final diagnosis is confirmed through histopathological examination with stratified squamous epithelium findings in the cystic fluid lumen or keratin. The treatment is usually surgical and without recurrence and the final diagnosis is confirmed through histopathological examination. This paper aims to present a case report of a congenital epidermal cyst in a 5-month-old female patient located in the mouth floor near the sublingual gland duct. The case was treated with excisional biopsy and after follow-up, there was no recurrence.


RESUMO O cisto epidérmico é um cisto de desenvolvimento, benigno, raro, localizado com maior frequência na região submandibular, geralmente assintomático e de evolução lenta. Acredita-se que a sua etiologia esteja associada aos restos epiteliais retidos na linha média durante o fechamento do primeiro e segundo arcos braquiais, na terceira ou quarta semana de vida intrauterina. Suas características clínicas são de uma consistência borrachóide à palpação, bordas delimitadas e sem apêndices de pele no seu interior. O diagnóstico é confirmado através do exame histopatológico com achados de epitélio escamoso estratificado e no lúmen fluído cístico ou queratina. O tratamento é geralmente cirúrgico e sem recidivas. Este trabalho relata um caso de cisto epidérmico congênito de uma paciente pediátrica, do sexo feminino, de cinco meses de idade e localizado no assoalho de boca próximo ao ducto da glândula sublingual. O caso foi tratado com a enucleação cirúrgica e em seis meses de acompanhamento não apresentou recidiva.

ABSTRACT

An idiopathic bone cavity (IBC) tends to rise as an abnormality in osseous growth, a degenerating tumoral process, or triggered by hemorrhagic trauma. This paper describes the interpretation of an IBC and its progression over one year. The patient's initial radiographic images showed well-defined multilocular radiolucency located at the right mandibular molar region, extending between the teeth and the mandibular basis. No clinical symptoms were present, and the course of the mandibular canal was not altered. The lesion was not initially biopsied due to the patient's dental anxiety. Over one year, the radiolucent area extended anteriorly and thinned the lingual and buccal cortices. Prior radiolucent areas changed to granular-appearing bone. The diagnosis was based on a fine-needle aspiration biopsy. The appearance of an IBC is not unique; its benign nature should be differentiated from multilocular or fibro-osseous lesions by a careful interpretation of clinical and radiological perspectives.

ABSTRACT

The nasopalatine duct cyst (NPDC) is the most common non-odontogenic cyst typically found in middle-aged Caucasian female in Brazil, however the present report describes a case in a 35 year-old black male. NPDC are usually asymptomatic and are discovered incidentally during routine radiological examination. A cone-beam computed tomography (CBCT) is a valuable tool to localize a cyst within the nasopalatine canal. CBCT enables analysis of the dimension of the NPDC, analysis of the involvement of neighboring anatomical structures and assists in treatment planning. The authors at this case highlight the importance of clinical examination with an unbiased view of age, gender and ethnicity.


O cisto do ducto nasopalatino (CDNP) é o mais comum dos cistos não-odontogênicos geralmente encontrado em mulheres brancas de meia idade no Brasil, embora o presente relato descreva um caso em um homem negro de 35 anos de idade. Os CDNP são usualmente assintomáticos e são descobertos acidentalmente durante o exame radiográfico de rotina. A tomografia computadorizada por feixe cônico(TCFC) é uma ferramenta válida para localizar o cisto dentro do canal nasopalatino. A TCFC permite análise da dimensão do CDNP, análise do envolvimento das estruturas anatômicas vizinhas e auxilia no planejamento do tratamento. Os autores neste caso alertam para a importância do exame clinico, com uma visão embasada na idade, gênero e grupo étnico.

ABSTRACT

The purpose of this study was to determine the prevalence of odontogenic cysts and to identify their clinico-pathological features among patients by studying biopsy specimens obtained from the archives of the Department of Oral and Maxillofacial Pathology, College of Dental Sciences, Davangere, Karnataka, India, during the past 10 years. Data for the study were retrieved from the case records of patients fitting the histological classification of the World Health Organization (1992). Analyzed clinical variables included age, gender, anatomical location, and histological diagnosis. Of the 2275 biopsy reports analyzed, 194 cases (8.5%) were jaw cysts, including odontogenic (6.7%) and nonodontogenic cysts (0.25%). Odontogenic cysts included 69.3% radicular, 20.3% dentigerous, 5.2% keratinizing odontogenic, 3.3% residual, and 1.9% other cysts, such as lateral periodontal, botryoid odontogenic, and gingival cysts. The most frequent clinical manifestation was swelling, followed by a combination of pain and swelling. Age, gender, and location were related to the etiopathologic characteristics of the cyst type. A definitive diagnosis can be made on the basis of clinical, radiological, and histological findings, which makes a good interdepartmental relationship between the clinicians and pathologists essential. Knowledge of the biological and histological behavior of the odontogenic cysts is required for their early detection and treatment.

ABSTRACT

O cisto ósseo traumático é uma entidade patológica caracterizada pela presença de uma cavidade óssea assintomática desprovida de revestimento epitelial, sendo raramente encontrado nos maxilares. OBJETIVO: Descrever as características clínico-cirúrgicas e radiográficas dos cistos ósseos traumáticos. MATERIAL E MÉTODO: Estudo de caráter retrospectivo dos pacientes diagnosticados com cisto ósseo traumático em um serviço de patologia oral no período de 1992 a 2007. Informações referentes às características clínicas, radiográficas e cirúrgicas foram coletadas. RESULTADOS: Vinte e seis casos de cisto ósseo traumático foram diagnosticados no período de 15 anos, 17 pertencentes ao sexo masculino e 09 ao sexo feminino. A maioria dos pacientes afetados pertencia às duas primeiras décadas de vida, não relatava sintomatologia dolorosa, bem como história de trauma na região da lesão. O padrão multilocular foi observado em apenas sete casos, dando às lesões uma aparência radiográfica tumoral. A presença de ar no interior da cavidade patológica foi relatada em aproximadamente 70% dos casos, sendo rara a presença de conteúdo serossanguíneo e seroso. CONCLUSÃO: A maior prevalência de casos em pacientes jovens, a infrequente história de trauma e o pequeno número de lesões com conteúdo serossanguíneo refletem a necessidade de se discutir a real patogênese do cisto ósseo traumático.


The traumatic bone cyst is characterized by the presence of an asymptomatic sinus devoid of epithelial lining, which is rarely found in the jaws. OBJECTIVE: To describe the clinical, surgical and radiographic findings of traumatic bone cysts. MATERIAL AND METHOD: A retrospective study was made of patients diagnosed with traumatic bone cysts at an oral pathology department from 1992 to 2007. Data on the clinical, radiographic and surgical complications were gathered. RESULTS: Twenty-six cases of traumatic bone cyst were diagnosed in 15 years; 17 were male and 09 were female. Most patients were within first two decades of life and had no pain or history of trauma in the affected area. The multilocular pattern was observed in only seven cases, its radiographic appearance suggests a tumor. Air was found inside the lesion in about 70% of cases; serous fluid with blood and blood only were uncommon within the lesions. CONCLUSION: A higher prevalence in young patients, absence of a history of trauma, and a small number of lesions containing serous fluid with blood reflects the need to discuss the true pathogenesis of traumatic bone cysts.

ABSTRACT

PURPOSE: To describe the behavior clinical and pathological features of two cases of odontogenic cyst orthokeratinized. CASE DESCRIPTION: In case 1, a 17-year-old woman presented hard and painless swelling in the left posterior mandible. Radiographically, a radiolucent area with a radiopaque was observed. A clinical diagnosis of ameloblastoma or odontogenic keratocystic tumor was established. The histopathological examination revealed an orthokeratinized odontogenic cyst. In case 2, a 23-year-old woman presented a radiolucent lesion surrounded by radiopaque halo symmetrically distributed on both partially erupted lower third molars. A clinical diagnosis of bilateral dentigerous cyst (DC) was rended. The histopathological examination showed bilateral orthokeratinized odontogenic cyst. CONCLUSION: Orthokeratinized odontogenic cyst should be considered in the differential diagnosis of lesions occurring in the jawbones associated with an impacted tooth, particularly those cases simulating dentigerous cyst. In addition, we observed the importance of radiographs taken prior to orthodontic treatment as an important tool in the diagnosis of oral pathologies. Performing routine radiograph is of high clinical value, especially before orthodontic treatment.


OBJETIVO: Descrever os aspectos clinicopatológicos de dois casos de cisto odontogênico ortoqueratinizado e a compará-los a relatos anteriores. RELATO DO CASO: No caso 1, uma mulher de 17 anos de idade, apresentou edema endurecido e indolor na mandíbula posterior esquerda. Radiograficamente, uma área radiolúcida com uma radiopacidade foi observada. O diagnóstico clínico de ameloblastoma ou tumor odontogênico ceratocístico foi estabelecido. O exame histopatológico revelou um cisto odontogênico ortoqueratinizado. No caso 2, uma mulher de 23 anos apresentou duas lesões radiolúcidas circundadas por halos radiopacos simetricamente distribuídas, associada aos terceiros molares inferiores irrompidos. Um diagnóstico clínico de cisto dentígero bilateral (DC) foi estabelecido. O exame histopatológico mostrou ser um cisto odontogênico ortoqueratinizado. CONCLUSÃO: Cisto odontogênico ortoqueratinizado deve ser considerado no diagnóstico diferencial das lesões que ocorrem na mandíbula associado com dentes impactados, especialmente aqueles casos que simulem o cisto dentígero. Além disso, observamos a importância de tomadas radiográficas antes do tratamento ortodôntico no diagnóstico de patologias bucais.

ABSTRACT

Postoperative maxillary cyst is a rare complication of surgical intervention associated with maxillary sinuses. The present paper describes a 25-year-old man presenting with a lump sensation in the left cheek area after Le Fort I osteotomy and mandibular sagittal split osteotomy. The orthopantomograph revealed a bony defect in the left maxillary alveolus. On the computerized tomography, a 1x2x3cm sized, lower density mass, between the left paramedian side of the maxillary alveolar process and hard palate was observed. The cyst was drained and enucleated. More frequent post-operative maxillary cysts may occur with an increase of Le Fort I osteotomies.

ABSTRACT

O cisto do ducto nasopalatino é não odontogênico do tipo fissural, de ocorrência pouco freqüente, que provavelmente se desenvolve pela proliferação de restos epiteliais incluídos no interior do canal nasopalatino por ocasião da fusão dos processos palatinos com a pré-maxila. O presente relato objetivou contribuir ao estudo com a descrição das características de um caso clínico, que se referia a uma lesão assintomática identificada ao exame radiográfico panorâmico para implante dental. A lesão apresentava imagem radiolúcida com aproximadamente 15mm de diâmetro delimitado por halo radiopaco, localizada no palato duro região de forame nasopalatino. Foi realizada biópsia excisional observando-se à microscopia óptica presença de cavidade cística revestida por epitélio composto por duas camadas de células de aspecto cúbico e cápsula fibrosa envolvendo todo o conjunto, com resultado histopatológico de cisto nasopalatino. A evolução pós-operatória ocorreu de acordo com o descrito na literatura para esse tipo de lesão, dentro dos limites favoráveis de reparação e sem sinais clínicos e/ou radiográficos de recidiva após dois anos.


The nasopalatine duct cyst is a non odontogenic cyst whose occurrence is little frequent, probably originating from proliferation of remains epithelial cells included inside the nasopalatine duct by occasion of the coalition of the palatine processes with the anterior maxilla. The present report aimed at to contribute to the study with the description of the characteristics of a clinical case that refers to an asymptomatic lesion identified in radiographic exam for dental implants. It was made excisional biopsy being observed to the optical microscopy presence of cystic cavity covered by epithelium composed by two layers of cells of cubic aspect and fibrous capsule involving the whole group, with the histopathological result of nasopalatine duct cyst. The postoperative evolution happened in agreement with described in the literature for that lesion type, inside of the favorable limits of repairing and without clinical or radiographic recurrence signs after two years.

ABSTRACT

O cisto naso-labial é cisto não odontogênico raro e de evolução lenta que, dependendo do tamanho, pode causar assimetria facial. O tratamento do cisto naso-labial comumente, e com sucesso, se dá por enucleação cística com acesso intra-oral. Existe um potencial risco de formação de uma fístula oro-nasal na enucleação cística por acesso intra-oral, devido à proximidade desse cisto com a mucosa nasal. A marsupialização por via nasal pode ser uma opção no tratamento do cisto naso-labial com menor risco de formação de fístula oro-nasal. O presente artigo relata um caso de cisto naso-labial tratado por marsupialização com acesso via transnasal


The nasolabial cyst is a rare nonodontogenic cyst of slow progression which, depending on its size, can cause facial asymmetry. It is commonly and successfully treated by enucleation, using an intra-oral approach. There is a potential risk of an oronasal fistula when this modality of treatment is employed, owing to the proximity of the cyst to the nasal mucosa. Transnasal marsupialization can be an option in the treatment of the nasolabial cyst as there is a lower risk of formation of an oronasal fistula. The present paper reports a case of nasolabial cyst treated by marsupialization, using a transnasal approach
