AbstractOdontogenic cysts are benign non-neoplastic lesions that originate from epithelial cells Arachnida-Araneae) community in the process of the teeth development. Among them, the odontogenic keratocyst is a developmental cyst characterized by its epithelium of parakeratinized stratified and aggressive squamous cells as well as infiltrative behavior. Thus, the objective of this study was to describe a clinical case of surgical treatment of odontogenic keratocysts in a 52-year-old female patient, who presented for the treatment of a large lesion in a region of the left mandibular body and angle. After incisional biopsy and installation of a decompression device, the histopathological diagnosis of odontogenic keratocyst was obtained. Subsequently to a period of 9 months with the decompression device in place, a decrease of the lesion was noticed, thus allowing intervention to be performed the excision of the lesion. Thus, the patient was subjected, under general anesthesia, to enucleation of the lesion as the main treatment, with complementary maneuvers of peripheral ostectomy and application of Carnoy solution over the remaining bone bed. After an outpatient follow-up of 16 months, no signs of recurrence of the lesion were observed. The proposed treatment was efficient in removing the keratocyst with minimal surgical morbidities. In conclusion, the treatment protocol was effective and conservative in the surgical management of the lesion, allowing rapid recovery and return of the  function.       Keywords: Bone Cysts.

Dentre elas, o queratocisto odontogênico é um cisto de desenvolvimento caracterizado por seu epitélio de células escamosas estratificadas paraqueratinizadas, pelo comportamento agressivo e infiltrativo. Sendo assim, o objetivo desse estudo foi descrever um caso clínico de tratamento cirúrgico do queratocisto odontogênico em uma paciente do gênero feminino de 52 anos de idade, que compareceu para o tratamento de uma lesão de grande porte em região de corpo e ângulo mandibulares à esquerda. Após biópsia incisional e instalação de um dispositivo descompressivo, obteve-se o diagnóstico histopatológico de queratocisto odontogênico. Posteriormente a um período de 9 meses com o dispositivo de descompressão em posição, notou-se uma diminuição da lesão, permitindo assim a execução de intervenção para exérese da lesão. Assim, a paciente foi submetida, sob anestesia geral, à enucleação da lesão como tratamento principal, com manobras complementares de ostectomia periférica e aplicação de solução de Carnoy sobre o leito ósseo remanescente. Após um acompanhamento ambulatorial de 16 meses, não foi observado nenhum sinal de recorrência da lesão. O tratamento proposto foi eficiente em remover o queratocisto com as mínimas morbidades cirúrgicas. Concluindo, o protocolo de tratamento foi efetivo e conservador no manejo cirúrgico da lesão, permitindo rápida recuperação e retorno da função. Palavras-chave: Cistos Ósseos. Descompressão.

Goltz Syndrome

Multiple Odontogenic keratocysts with multi-organ abnormalities are a feature of Gorlin-Goltz Syndrome (GGS) which is an autosomal dominant inherited disorder. The most common oral manifestation of GGS is odontogenic keratocyst. Early diagnosis of GGS without cutaneous manifestations is important as this syndrome has basal cell carcinoma as one of its major criteria. This paper includes a case report of a 24-year-old female who reported with swelling and pus discharge in lower right posterior region. The swelling was clinico-radiologically diagnosed as odontogenic keratocyst on a panoramic radiograph which revealed the presence of multiple cystic lesions in symphysis, parasymphysis, and bilateral maxillary region. Postero-Anterior (PA) chest showed bifid ribs and PA skull showed calcification of falxcerebri. Histopathological diagnosis confirmed the Odontogenic keratocyst. Ultrasonography (USG) abdomen revealed a simple ovarian cyst on the right side. Clinical examination findings and radiological imaging evaluation with histopathological examination of cystic lesion confirms Gorlin-Goltz. Surgical enucleation of the keratocyst, peripheral ostectomy followed by bone graft substitute, and primary closure under General Anaesthesia (GA) were done in the Department of Oral and Maxillofacial Surgery. Follow-up healing was uneventful after one month.

F.NA.C has been used for ages as a safe and economical tool for fast preoperative diagnosis of parotid tumors. It has certain pitfall which sometimes leads to misdiagnosis and consequently it may have affect on treatment of the tumors. Keeping in view of the diverse classification of parotid tumors’ information from cytology should be combined with radiology as well as clinical diagnosis. Aim: To discuss some cases where there was discrepancy between cytological diagnosis and histopathological result and also suggest measures to improve the efficacy of F.N.A.C. Material and methods: The study includes 50 cases of parotid tumours who presented to the  department of ENT at Government medical college Haldwani which is a tertiary referral centre during 2009 to 2016. Only adult patients were included and inflammatory swelling were excluded from the study. All patients evaluated  Contrast enhanced computerized tomography(CECT) and  Magnetic resonance imaging (MRI) followed by Fine needle aspiration cytology .Preoperative diagnosis was made upon the findings of the above investigations and different types of  parotid surgeries  were done. . Final diagnosis was made on  histopathological  examination. Result :The most common tumour  came out to be pleomorphic adenoma (23 cases-46%) followed by mucoepidermoid carcinoma(12cases-24%). In ten  cases there was no clear cut  association between cytological diagnosis and final histopathological diagnosis. Conclusion: FNAC is highly sensitive and specific technique for diagnosis of many salivary gland swellings. FNAC can be used preoperatively to avoid unnecessary surgery and biopsy. Details of clinical information and radiologic features may help the pathologist to arrive at the appropriate diagnosis and reduce false interpretation. Pitfalls may also occur with improper technique of FNAC which can be overcome by proper caution.

SummaryA 2-year-old male neutered mixed breed dog with a body weight of 30 kg was presented for evaluation of a soft subcutaneous mass on the dorsal midline at the level of the caudal thoracic spine. A further clinical sign was intermittent pain on palpation of the area of the subcutaneous mass. The owner also described a prolonged phase of urination with repeated interruption and re-initiation of voiding. The findings of the neurological examination were consistent with a lesion localization between the 3rd thoracic and 3rd lumbar spinal cord segments. Magnetic resonance imaging revealed a spina bifida with a lipomeningocele and diplomyelia (split cord malformation type I) at the level of thoracic vertebra 11 and 12 and secondary syringomyelia above the aforementioned defects in the caudal thoracic spinal cord. Surgical resection of the lipomeningocele via a hemilaminectomy was performed. After initial deterioration of the neurological status postsurgery with paraplegia and absent deep pain sensation the dog improved within 2 weeks to non-ambulatory paraparesis with voluntary urination. Six weeks postoperatively the dog was ambulatory, according to the owner. Two years after surgery the owner recorded that the dog showed a normal gait, a normal urination and no pain. Histopathological diagnosis of the biopsied material revealed a lipomeningocele which confirmed the radiological diagnosis.

Spinal Epidural

Spinal epidural hemangioma, mostly cavernous, is a rare lesion with many radiological mimics that has diagnostic difficulty. They can extend from one to multiple vertebral levels and may or may not be associated with vertebral hemangiomas. We are reporting a case of young adult presenting with features of compressive myelopathy. Plain and contrast-enhanced magnetic resonance imaging showed a large spinal epidural lesion extending from C7 to D10 vertebral levels with extension into adjacent neural foramina and paravertebral spaces. There were also signal changes in bodies and posterior elements of dorsal vertebrae. A provisional diagnosis of lymphoma was made. The patient was operated for decompression and histopathological diagnosis of cavernous hemangioma was made. As in our case, a review of literature shows that epidural cavernous hemangioma of spine may extend to multiple vertebral levels and difficult to diagnose on pre-operative imaging. However, such a long segment epidural cavernous hemangioma has not been reported in literature. Furthermore, we should be aware of these rare lesions to include it in our differential diagnosis the spinal epidural lesions for early diagnosis and management.
