Um caso raro de carcinoma mucoepidermóide de septo nasal

Introducao: O carcinoma mucoepidermoide e a neoplasia maligna mais comum das glândulas salivares, sendo o principal sitio de acometimento a parotida. Ocorre tambem em glândulas salivares menores desde a cavidade nasal ate os pulmoes. A localizacao nasal do carcinoma mucoepidermoide e extremamente rara. A literatura e pobre em casos semelhantes. Objetivo: Relatar um caso de carcinoma mucoepidermoide de septo nasal a direita, abordando aspectos gerais quanto a patogenese, diagnostico, terapeutica e seguimento pos-operatorio. Relato do Caso: Apresentamos um caso de uma paciente de 32 anos com historia de obstrucao nasal, epistaxe e tumoracao em fossa nasal direita. A biopsia revelou tratar-se de carcinoma mucoepidermoide. Realizamos resseccao tumoral por via nasal endoscopica, associada a radioterapia complementar. O anatomo-patologico classificou-o como de alto grau de malignidade. Obteve remissao dos sintomas e sem recidiva em seguimento. Conclusao: As massas tumorais nasais devem ser estudadas com exames de imagem e histopatologia. Podemos nos surpreender com tumores malignos nasais raros. Introduction: Mucoepidermoid carcinoma is the most common malignant neoplasm of the salivary glands, and the parotid is the main site of attack. It also occurs in the minor salivary glands from the nasal cavity to the lungs. Nasal location of the mucoepidermoid carcinoma is extremely rare. There is little literature on similar cases. Objective: To report a case of mucoepidermoid carcinoma of the right nasal septum, and cover general aspects of the pathogenesis, diagnosis, therapy, and post-operative follow-up. Case Report: We present a case of a 32-year-old patient with a history of nasal obstruction, epistaxis and tumoration in the right nasal cavity. The biopsy revealed it was a mucoepidermoid carcinoma. The tumor was surgically removed using endoscopes with associated complementary radiotherapy. The anatomopathological analysis classified it with a high degree of malignancy. We obtained remission of the symptoms and without subsequent recurrence. Conclusion: Tumor nasal masses should be studied with imaging and histopathology examinations. We may discover rare malignant nasal tumors.
