Tratamento Clínico e Cirúrgico de Hiperplasia Palatina Causada por Câmara de Sucção

ResumoA hiperplasia palatina por câmara de sucção ou hiperplasia inflamatória do palato está associada ao uso de prótese totais superiores com câmara de vácuo, acometendo de 1% a 11% dos indivíduos que fazem uso de próteses totais. Odiagnóstico é realizado através do exame clínico, com uma maior incidência em pacientes na 5a e 6a décadas de vida e que fazem o uso da mesma prótese há mais de 15 anos. É apresentado o tratamento de um caso de hiperplasia palatina causada pela câmara de sucção numa paciente que fazia o uso da mesma dentadura há mais de 15 anos, com completa resolução do caso.AbstractThe palatine hyperplasia caused by suction chamber or the palatine inflammatory hyperplasia is associated to suction chambers confectioned on totally prosthesis, been present in 1% to 11% of all the patients that ware this type of prosthesis.

Giant tongue lipoma

Lipomas are the most common soft tissue mesenchymal neoplasms are uncommon in the oral and maxillofacial region. Oral lipomas usually exhibit slow asymptomatic growth and are less than 20 mm at their largest diameter. A 71-year-old man was referred to our regional oral and maxillofacial department by a dentist after noticing an asymptomatic tongue swelling. Examination and further radiographic and histological investigations revealed a large tongue lipoma which had been present for over three years. Initially it was decided to keep this benign lesion under review. However its relatively rapid growth over the next six months started to affect his speech, eating and airway and was subsequently removed surgically under general anaesthetic. This unusual case report documents the presentation, diagnostic considerations and treatment of this lipoma. It also highlights the important role clinicians have in detecting and investigating or referring any abnormal pathology. Keywords: Lipoma, Tongue, Diagnosis, Histopathology, Treatmen

Central odontogenic fibroma: a case report

Central odontogenic fibroma is a rare odontogenic neoplasm that originates from odontogenic ectomesenchyme. Here, a case of central odontogenic fibroma in a 17-year-old male is reported. Since the present case showed a multilocular radiolucency with partially ill-defined border between the right mandibular condyle and the distal root of the right mandibular third molar, differential diagnosis involved a wide range of pathosis from benign lesions like ameoloblastic fibroma and odontogenic myxoma to more aggressive lesions such as desmoplastic fibroma, juvenile aggressive fibromatosis, or fibrosarcoma

Clinical Features and Differential Diagnoses in Laryngeal Mucoepidermoid Carcinoma

Mucoepidermoid carcinoma is the most common malignant tumor of salivary glands. However, it is a rare entity in larynx. Laryngeal cases are frequently misdiagnosed with other malignancies and they are under-reported. So, recognizing the clinical and histological features of this tumor is essential. Laryngeal mucoepidermoid carcinoma can arise in supraglottis, glottis and subglottis. Generally, it presents as a submucosal mass; therefore, progressive symptoms without any identifiable lesion in laryngoscopy must be well considered. The prognosis is somehow dependent on the histological features. In high-grade tumors, recurrence is more common and radical surgery with radiotherapy is recommended. In this paper, we provide a thorough literature review on mucoepidermoid carcinoma in the larynx. The most important distinguishing features of mucoepidermoid carcinoma and its two major differential diagnoses (squamous cell carcinoma and adenosquamous carcinoma) are clearly stated and pitfalls in true diagnosis of this tumor are discussed

Polymorphous low-grade adenocarcinoma of the tongue: a case report

<p>Abstract</p> <p>Introduction</p> <p>Polymorphous low-grade adenocarcinoma is a distinct neoplasm of the salivary gland composed of luminal and non-luminal tumor cells admixed in varying proportions. Its resemblance to lobular carcinoma of the breast had led to its earlier nomenclature of 'terminal duct carcinoma'. Most patients present with an asymptomatic mass in the hard palate. In rare cases, the mass can also occur in the tongue. We report an unusual case of polymorphous low-grade adenocarcinoma at the base of tongue.</p> <p>Case presentation</p> <p>A 47-year-old Asian Caucasian woman presented with a painless swelling at the right lateral border of the tongue with an intact overlying mucosa. There were no other associated complaints. The lesion was excised and subjected to histopathological examination that revealed an interesting and unusual morphology of polymorphous low-grade adenocarcinoma.</p> <p>Conclusion</p> <p>Polymorphous low-grade adenocarcinoma is a well-defined entity in the minor salivary glands. Its occurrence in the tongue is rare with very few cases reported in the literature. It is a malignant neoplasm with low aggressiveness and it is thus important to identify and treat it accordingly.</p
