Resumo      O Ceratocisto Odontogênico (CO)é uma lesão intraóssea benigna de origem odontogênica, que surge a partir dos restos celulares da lâmina dental; apresenta predominância de acometimento em mandíbula, principalmente com envolvimento do corpo posterior e ramo de mandíbula. Os COs podem ser encontrados em pacientes desde a infância até a velhice, todavia, mais da metade dos casos são diagnosticados em pessoas entre 10 a 40 anos de idade, sendo sua prevalência em homens. Tal lesão cística exibe ao exame radiográfico uma área radio lúcida, com margens escleróticas frequentemente bem definidas. Histologicamente manifesta revestimento epitelial composto por uma camada uniforme de epitélio escamoso estratificado, geralmente com 6 ou 8 camadas de espessura, podem ser observados ainda pequenos cistos, cordões ou ilhas satélites de epitélio odontogênico na cápsula fibrosa, a qual é tipicamente delgada e friável. O objetivo do presente trabalho é relatar o caso clínico do paciente BSM,sexo masculino, feoderma, 22 anos de idade, ASA I, que compareceu ao ambulatório de Buco-Maxilo-Facial do Hospital Federal de Ipanema/RJapresentando uma lesão cística associada ao terceiro molar superior direito incluso. O tratamento consistiu na enucleação e curetagem da lesãoem ambiente hospitalar sob anestesia geral, sem presença de intercorrências. A peça cirúrgica foi encaminhada ao Laboratório de Biotecnologia Aplicada da Universidade Federal Fluminense (LABA-UFF) para exame anatomohistopatológico, sendo confirmado seu diagnóstico inicial de CO. O paciente recebeu alta no dia seguinte ao procedimento cirúrgico e segue em acompanhamento ambulatorial de 12 meses pela especialidade, sem presença clínica e imaginológica de recidiva da lesão. Palavras-chave: Ceratocisto Odontogênico; Enucleação; Maxila Abstract  The Odontogenic Keratocyst (CO) is a benign intraosseous lesion of odontogenic origin, which increases from the cellular remains of the dental membrane; it presents predominance of follow-up in the mandible, mainly with involvement of the posterior body and mandible branch. OCs can be found in patients from childhood to old age, however, more than half of the cases are diagnosed in people between 10 and 40 years of age, being its prevalence in men. Such a cystic lesion is detected in the radiographic examination of a radiolucent area, with sclerotic margins often quite reduced. Histologically, the epithelial lining composed of a uniform layer of stratified stratified epithelium, with 6 or 8 layers of thickness, can also be observed in small cysts, cords or satellite islands of odontogenic epithelium in the fibrous capsule, which is typically thin and friable. The objective of the present work is to relate the clinical case of BSM patient, male, feoderma, 22 years old, ASA I, who compared the cystic lesion associated with the included dental element to the buccomaxillofacial clinic of the Federal Hospital of Ipanema / RJ. Treatment consists of enucleation and curation of lesions in the hospital environment under general anesthesia, without the presence of complications. A surgical specimen was sent to the Laboratory of Applied Biotechnology by Universidade Federal Fluminense (LABA-UFF) for anatomo-histopathological examination, confirming its initial diagnosis of OC. The patient who was discharged the day after the medical procedure and is undergoing outpatient follow-up for 12 months, with no clinical and imaginative presence of injury recurrence. Keywords: Odontogenic Keratocyst; Enucleation; Maxilla

Introduction: Avulsion has been described as the traumatic displacement of the tooth out of the socket, and it accounts for 0.5% to 16% of traumatic injuries in the permanent dentition. Many complications have been associated with avulsed tooth following replantation. This paper aimed at presenting a case of the large cystic lesion following replantation of avulsed teeth. Case Presentation: A case of a 17-year-old undergraduate student who presented in the dental clinic for medical screening as a mandatory exercise upon gaining admission. During the examination, a purulent pus discharge was noticed on the labial sulcus about tooth 11. History revealed that she had avulsion of teeth 11 and 12 about 4-years earlier that was replanted and splinted for 2-3 weeks and subsequently she was discharged from the clinic without any further treatment. Radiographic examination revealed periapical radiolucency without well define margin about teeth 11 and 12. Periapical surgery was carried out and two large cystic cavities were seen at about teeth 11 and 12 during surgery. The histology report of the specimen revealed a benign lesion suggesting periapical cyst. Conclusion: There is the need for adequate follow-up and monitoring of replanted teeth the following avulsion to arrest any complication that might arise from the procedure. Also, the importance of endodontic treatment following replantation of the avulsed tooth cannot be overemphasized.

Ameloblastic fibro-odontoma (AFO) predominantly occurs in the jaw bones of children and young adults. Extraosseous AFO is extremely rare. We describe a peripheral ameloblastic fibro-odontoma in the maxillary gingiva of a 3-year-old girl. The clinical appearance resembled fiery red reactive gingival lesions. The histopathological examination of the excised lesion showed small islands and cords of odontogenic epithelium with cellular myxoid stroma in the subepithelial tissue. The mass contained calcified material and an enamel-like deposit. Many small blood vessels appeared in the connective tissue surrounding the odontogenic epithelium. The immunohistochemical assays showed strong reactivity for amelogenin,β-catenin, CD44, and CD31 in the tissue sections. There was no recurrence after the 1-year follow-up. Because this lesion clinically resembles other nonneoplastic lesions and is very rare in gingiva, establishing a correct diagnosis is achieved only based on specific histological characteristics. Conservative excision of the tumor is the treatment of choice.

Laryngeal oncocytic cystadenomas are rare benign tumours lined by oncocytic epithelium and arising from the salivary glands; they usually present as a supraglottic mass. Oncocytic changes are very uncommon in the larynx and occur mainly in ventricles and false vocal cords, where seromucinous glands predominate. The authors present the case of a 62-year-old woman who reported a 6-month history of hoarseness associated with a soft and non-compressible upper left side neck swelling. Transnasal fiberoptic laryngoscopy revealed a left submucosal supraglottic mass involving the false vocal fold and the vallecula, partially obstructing the airway. CT scan showed a homogeneous isodense cystic lesion centred at the left laryngeal ventricle, with extension through the thyrohyoid membrane. The patient was successfully managed by a lateral thyrotomy approach. Histopathological examination of the specimen revealed a papillary oncocytic cystadenoma and excluded malignancy. There was no evidence of recurrence after 9 months of follow-up.

Adenomatoid Odontogenic Tumour

Adenomatoid Odontogenic Tumour (AOT) is a relatively uncommon benign odontogenic tumour composed of odontogenic epithelium in a variety of histoarchitectural patterns. Conventional AOT is predominantly seen in females in second decade of life exhibiting predilection for anterior region of maxilla. Very few cases of AOT associated with dentigerous cyst have been reported till date. The present case is unique associated with an impacted lower first premolar in the front region of the mandible of an 18-year-old female patient. The patient reported to the institute with gradually increasing swelling. The orthopantomogram revealed a unilocular radiolucency with displaced premolar. Histopathological examination confirmed 4×2.5×2 cm lesion in dimension, brownish black in colour, firm in consistency with a smooth surface grossly while cut surface revealed a cystic lumen with an impacted premolar embedded into the lining, cystic wall being nodular. Microscopic evaluation revealed a well encapsulated lesion with a thin 2-3 cell layered non keratinised stratified epithelial lining in patterns such as nests, rosette like structures and duct like structures. Thus the diagnosis of AOT arising from dentigerous cyst was confirmed. Patient's six month follow-up was uneventful. Literature search of similar cases with the review of hypothesised aetiopathogenesis is discussed in brief. The available data can help researchers resolve the uncertainty whether the AOT derived from dentigerous cyst could represent a distinct hybrid variety.

ABSTRACT Background The solitary bone cyst is an uncommon nonepithelial cyst. Clinically, the lesion is asymptomatic in the majority of cases and is often accidentally discovered on routine radiological examination, frequently during the second decade of life. Its pathogenesis is still not clearly understood. The majority of solitary bone cysts are located in the mandibular body. This article presents two case reports, one in whom a cyst was diagnosed on routine radiographic examination and other patient reported with dull ache and radiographic examination showed bilateral presentation of the cystic lesion. Materials and methods In both patients the biopsy was planned. On surgical opening the lesions presented empty cavities. Curettage was done and overlying bone sent for histopathological examination. Both patients were followed for 1 year. Results At follow-up visit both patients were examined clinically and radiographically. In both the patients resolution of the lesion was seen at follow-up visit. Conclusion Solitary bone cyst is a rare entity with typical clinical and radiographic features. However, confirmation of diagnosis can be made only by histological examination. Solitary bone cyst may be secondary to an underlying bone pathology. Solitary bone cyst of the head and neck may vary in presentation and severity. Surgical removal is the treatment of choice and provides a satisfying outcome.

Keratocystic Odontogenic Tumour

Odontogenic Keratocyst (OKC) is a benign odontogenic cystic lesion which arises from dental lamina lined by parakeratinized stratified squamous epithelium. Odontogenic Keratocyst is (OKC) also termed as Keratocystic Odontogenic Tumour (KCOT) (WHO 2005). Most frequently it involves posterior of the mandible than maxilla. OKC in the maxillary sinus is rarely reported. The treatment approaches vary in case to case manner. However regular follow up for minimum of five years is required.

ABSTRACT Focal cemento-osseous dysplasia (FCOD) is a benign fibroosseous condition that can be seen in dentulous and edentulous patients. It is an asymptomatic lesion and needs no treatment; however, follow-up is essential due to the possibility that it can progress to a condition called florid cemento-osseous dysplasia. Clinically, the lesion resembles periapical pathosis of odontogenic origin. FCOD is an asymptomatic lesion and occurs in the periapical area of teeth with vital pulps or in regions of extractions. The lesion is detected only on radiographic examination varying from completely radiolucent to densely radiopaque. The histopathologic appearance consists of trabeculae of bone and cementum like material present within a vascular fibrous stroma. Presented here is a case of FCOD in the mandible that occurred in the periapical region of a vital tooth. How to cite this article Kadam R, Patel S, Pathak J, Swain N, Kumar S.

Background: Synchronous primary malignancies of the female genital tract constitute 1.7% of all genital malignancies. Case: A 45-year-old para 5 woman presented with loss of appetite and abdominal distention. Provisional diagnosis of ovarian malignancy was made. Final histopathology of the specimen revealed ovarian papillary serous cystadenocacinoma with cervical leiomyosarcoma. She received chemotherapy. Results: Patient is on regular follow-up. Conclusion: The coexistence of primary neoplasms in the ovary and cervix are rare. A normal appearing organ may have a hidden malignancy. So, every surgical specimen should be subjected to detailed histopathological examination. Also, the possibility of synchronous malignancy elsewhere in body should be kept in mind while working on a genital malignancy.
