Clinical, pathological and therapeutic findings on lingual rhabdomyosarcoma in a dog - case report / Achados clínicos, patológicos e terapêuticos do rabdomiossarcoma em cão - relato de caso

The biological behaviour of the tumours vary according to the species in which they occur, its location within the cavity, clinical stage and histopathological nature. Lingual neoplasms are generally uncommon in companion animals. Rhabdomyosarcomas are malignant, solid, aggressive formations with high metastatic potential. The clinical signs are variable and a definitive diagnosis can only be reached through histopathological analysis of biopsy and necropsy specimen. In some cases, immunohistochemical study may be needed to confirm the diagnosis. This paper aims to highlight important points about this uncommon condition in dogs, using a case report of lingual rhabdomyosarcoma, which showed no evidence of metastasis after diagnosis, nor of local recurrence after surgical excision with a wide safety margin. It was concluded that early diagnosis, the correct interpretation of the complementary tests and the appropriate therapeutic approach contributed to improving the quality of life and survival of the patient in question.(AU)

O comportamento biológico dos tumores varia de acordo com a espécie animal, a localização na cavidade, a fase clínica e a natureza histopatológica. As neoplasias orais são geralmente incomuns em animais de companhia. Os rabdomiossarcomas são formações malignas, sólidas e agressivas, com alto potencial metastático. Os sinais clínicos são variáveis e o diagnóstico definitivo só pode ser alcançado por meio da análise histopatológica do material colhido. Em alguns casos, o estudo imuno-histoquímico pode ser necessário para confirmar o diagnóstico. Este trabalho tem como objetivo destacar pontos importantes sobre essa condição incomum em cães, utilizando um relato de caso de rabdomiossarcoma lingual, no qual não se evidenciaram metástases após o diagnóstico, nem recorrência local após a excisão cirúrgica com ampla margem de segurança.

Primary Extracranial Meningioma: A Rare Location.

Meningiomas are benign extraaxial tumors of the central nervous system (CNS). Extracranial meningiomas are extremely rare (2%) and can develop as a direct extension from a primary intracranial meningioma or as true primary extracranial meningioma originating from ectopic arachnoid cells. Only eight cases of primary meningioma in the jaw have been reported to date. Extracranial meningiomas are frequently misdiagnosed, resulting in inappropriate clinical management. The aim of this article was to describe the case of a man with an asymptomatic swelling in the right retromolar area over a period of 2 months. Cone beam computed tomography was performed to determine the extension and involvement of the adjacent structures. Histopathological findings and immunohistochemical analysis aided in the diagnosis of primary extracranial meningioma in the mandible and several aspects of this unusual neoplasm are reviewed. The treatment of choice was a partial resection of the mandible and reconstruction with autogenous iliac tricortical bone. Five years after surgery, the patient remains free of disease.

Introduction: despite the fact that the global incidence of oral cancer has increased, no epidemiological records are found in our town which would allow to update nationwide information and thus consolidate more accurate data about the behavior of this condition in our area. Objective: determine the characteristics of the behavior of oral cancer at a hospital in Cartagena de Indias, Colombia. Methods: a retrospective study was conducted of samples from patients with a presumptive diagnosis of oral cancer sent to the pathology laboratory of a hospital in Cartagena de Indias, Colombia, from 2007 to 2011. The total number of anatomopathological studies reviewed was 215, and 73 samples (33.9 percent) were selected from patients with a histopathologic diagnosis of oral cancer, as well as other samples from areas adjacent to the oral cavity, such as lymph glands, pharynx, larynx and maxillas. The variables studied were age, sex, origin, habits, year of diagnosis and histopathologic diagnosis. Results: 53 percent of the cases (n= 39) were women. The age range with the highest number of diagnoses was the 60-67 group (23 percent). Mean age was 66 years (± 14). The most common diagnosis was squamous cell carcinoma (86.3 percent of the cases). 93.2 percent of the patients were smokers. Conclusions: the most common diagnosis was squamous cell carcinoma. No significant differences were found between the sexes. The age bracket with the highest number of diagnoses was the sixth decade of life. Smoking was the habit most frequently related to oral cancer. 30.1 percent of the diagnoses were made in the year 2010, followed by 27.4 percent in 2011(AU)

Assessment of knowledge about oral cancer: study with students of public education

Introduction and Objective: To evaluate the level of knowledge about oral cancer of students attending public school in one city of Santa Catarina (Brasil). Material and methods: A descriptive crosssectional study, using primary data collection. Students of last year of elementary school and first year of high school, enrolled in public schools in the city of Itajaí (SC), in 2012, were the target population. The non-probability sample was obtained by convenience. Data were collected through a self-administered questionnaire structured with 13 questions divided into three fields. The level of knowledge was made based on pre-established scores. Results: 1149 instruments were analyzed (80.8% of the target population). The average age of the group was 15.5 years and 54.5% were female. The majority (78%) never had received information about oral cancer. Only 27.9% had cognizance about self-examination of the oral cavity. With regard to knowledge, 87.5% classified as unsatisfactory. For most issues the cognitive field did not identify a significant correlation between knowledge and the variables gender and education. When asked if they would like to participate in educational and preventive activities about oral cancer and other issues related to health, 72.6% expressed interest. Conclusion: The group did not have adequate knowledge on the subject of oral cancer. Facing this reality, and the positive attitude of respondents, the researchers designed and offered an educational program to the research subjects.

The oral cavity neoplasms represent approximately 5% of all neo-formations found in dogs and catsand in most cases they affect those animals at middle and advanced age. The biological behavior ofthe oral tumor depends on the species which it affects, the location in the cavity, the clinical stage andhistopathological nature. Among the oral neoplasms, the epulides, in their four forms, fibromatous,acanthomatous, giant cells and osseous have a great incidence, and in the dog they are the most frequenttumors in this location. The acanthomatous epulide is considered the most common tumor ofdogs rostral mandible, with great invasive power, causing degeneration of subjacent bone regions.Despite the vast array of therapeutic options available for this type of oral neoplasm, the surgicaltreatment is still the most commonly used. The present work aims at highlighting important pointsrelated to this extremely common affection in the veterinary dentistry, meaning that the early diagnosis,the correct interpretation of laboratory exams and adequate clinical procedure may contribute forbetter expectancy prognosis of the affected patients.(AU)

Isolated intra-oral granular cell tumor: report of two cases and review of the literature

Granular cell tumor (GCT) is a relatively uncommon lesion occurring in almost any part of the body, including the orofacial region. The tongue and the buccal mucosa are common intra oral sites. Although aggressive and malignant variants of this neoplasm have been described, most GCTs are benign. The histogenesis of the lesion still remains unknown. However, histochemical and ultra-structural studies propose the origin of the lesion from Schwann cells, striated muscle, mesenchymal cells, histiocytes and epithelial cells. The tumor generally occurs in middle-aged or older adults. The lesion is typically seen as an uninflamed asymptomatic mass measuring about two cm in diameter with reddish surface coloring. As most granular cell tumors are benign, surgical excision of the lesion is the treatment of choice. In this study, 2 oral GCT cases are presented, corresponding to 2 male patients, with a mean age of 27 years and a mean time of evolution of the lesions of 8 months. Both lesions were located on the tongue. Differential diagnoses include fibrous hyperplasia, minor salivary gland tumor, condyloma acuminatum and neurilemmoma. In all the cases a resection with safety margins of the lesions was carried out under local anesthesia. The samples were fixed and processed for histopathological study. The main clinical pathology and diagnostic features of this neoplasm are reviewed and discussed.

O tumor de celulas granulares (TCG) e uma lesao relativamente incomum que pode acometer qualquer parte do corpo, incluindo a regiao buco-maxilo-facial. A lingua e a mucosa bucal sao localizacoes intraorais comuns. Embora casos de transformacoes malignas e agressividade terem sido descritos, a maioria dos TCG sao benignos. A histogenese desta lesao continua desconhecida. No entanto estudos de imunohistoquimica e ultraestruturais sugerem que a lesao se origina das celulas de schwann, musculatura estriada, celulas mesenquimais, histiocitos e celulas epiteliais. O tumor geralmente ocorre na meia idade ou em pacientes idosos. A lesao e tipicamente vista como uma massa assintomatica nao inflamatoria que mede cerca de dois centimetros de diametro com uma superficie de coloracao avermelhada. A maioria dos tumores de celulas granulares sao benignos cuja excisao cirurgica e o tratamento de escolha. Neste estudo, 2 casos orais de TCG sao apresentados sendo ambos em pacientes do sexo masculino, com media de idade de 27 anos e tempo medio de evolucao da lesao de 8 meses. A localizacao de ambas as lesoes foi o dorso da lingual. O dignostico diferencial incluiu a hiperplasia fibrosa, tumor de glandulas salivares menores, condiloma aculminado e neiurilenoma. Em todos os casos a resseccao com margens de seguranca foi realizado sob anesthesia local. As amostras foram fixadas e processadas para o estudo histopatologicos. As principais caracteristicas clinicopatologicas e de disgnostico foram revisadas e discutidas.

Carcinoma escamoso oral em gato jovem / Squamous Cell Carcinoma Oral in Young Feline

Background: Oral neoplasms are common in cats. Just the percentage of oral squamous cell carcinoma (SCC) accounts for about 70% of all feline oral tumors also it is considered highly invasive and malignant. There are reports that the flea collar increases five times the risk oral SCC development. In addition, smoke exposure is also considered a risk factor, and the animals were exposed to tobacco when makes it self-cleaning. SCC well differentiated is characterized histologically by numerous keratin pearls formation and clearly evident intercellular bridges with poor mitotic activity and nuclear pleomorphism. The median age of cats with oral SCC is about 11-13 years, but, cats as young as three years and as old as twenty-one years have been previously reported. However, it was not found reports of oral SCC in cats at age younger than one year old. The aim of this article is reports one case of oral SCC feline at age of three months old. Five days after surgical procedure the patient returned to the veterinary and the owner report that it returned to eating well. Case: It was exanimate a three months old male mixed breed cat presenting oral volume increased and the biopsy test was suggested. However, the owner returned 3 months later when the animal showed tumor 6 cm in diameter, dysphagia, tongue protrusion, excessive salivation, halitosis and weight loss. It was indicated a wide surgical excision of tumoral mass. The tissue was submitted to histopathology. Discussion: The historical, macroscopic characteristics and predisponents factors may aid in carcinoma diagnosis, however, the cytologic or histological examination of tissue confirms this diagnosis. Therefore, the microscopic evaluation revealed a malignant neoplastic proliferation of stratified squamous epithelial cells desmosomal junctions evident, few foci keratin pearl formation and presence of mononuclear inflammatory reaction perifocal.(...)(AU)
