Cart ilaginous tumors of the larynx are extremely rare neoplasms that account for approximately one per cent of all tumors of this organ. Less than 0.1% correspond to chondrosarcomas. Chondroma and low-grade chondrosarcoma are the most common, 70-75% of these tumors arise on the endolaryngeal surface of the posterior lamina of the cricoid cartilage. The diagnosis of laryngeal chondrosarcoma is likely to be missed because of its infrequent occurrence and its indolent pattern of growth. The clinical presentation is varied and directly dependent on size and location of tumor: stridor, hoarseness, dyspnea or neck mass are commonly presented signs. The objective of this study was to show an unusual case of laryngeal chondrosarcoma originating from thyroid cartilage, discussing its clinical presentation, diagnosis, treatment and prognosis.

O carcinoma epidermóide da laringe é a sexta neoplasia mais comum, sendo uma das neoplasias malignas mais freqüen-tes na cabeça e pescoço, ocupando o segundo lugar imediatamente após o câncer da cavidade oral. Forma de estudo: Estudo clínico retrospectivo. Material e método: Entre os anos de 1991 e 2003, 24 pacientes portadores de lesões glóticas envolvendo a comissura anterior foram submetidos a laringectomia frontal anterior com epiglotoplastia descrita por Tucker e colaboradores no ano de 1979. Resultado: Nossos resultados confirmam aqueles encontrados em outras publicações. Não ocorreram mortes no pós-operatório e o seguimento foi relativamente simples. Todos os pacientes foram decanulizados e recuperaram um efetivo trato digestivo e aéreo. Conclusão: Nossos achados mostram que a laringectomia pela técnica de Tucker é uma cirurgia efetiva para o tratamento dos carcinomas glóticos que acometem a comissura anterior e a porção membranosa das cordas vocais com a motilidade preservada, pois tais lesões não devem ser tratadas pela ressecção endoscópica trans-oral ou por uma laringectomia fronto lateral. Squamous cell carcinoma of the larynx is the sixth most common neoplasia, being the second neoplasia of the head and neck, after oral cancer. Study design: Retrospective clinical study chart review. Material and method: From 1991 to 2003, 24 patients whose glottic lesions involving anterior comissure were operated with a reconstructive anterior frontal laryngectomy with epiglotoplasty, such as described by Tucker et al in 1979. Results: Our functional results confirm those reported in the previous publications. There were no post-operative mortalities and follow-up was usually uncomplicated. All patients underwent decanulation and were able to eat by tract normal. Conclusion: Our findings show that partial laryngectomy by Tuckers technique is an effective surgical approach for glottic carcinoma at the anterior comissure and the membranous portion of both vocal cords; considering these lesions cannot be adequately managed with transoral endoscopic surgery resection or fronto lateral partial laryngectomy.Palavras-chave: laringectomia parcial, técnica de Tucker, laringectomia frontal anterior.
Os autores relatam um caso de obstrução nasal unilateral, rinorréia purulenta e infecção crônica em um mulher de 57 anos causada por rinolito. A patologia mais freqüente-mente encontrada em associação com rinolitíase é a sinusite crônica. A rinolitíase é uma concreção calcária estratificada visível ao exame radiológico. O rinolito pode ser um achado acidental em alguns pacientes. Rinolitos são raros e podem ter várias apresentações clínicas. O tratamento de escolha é remoção cirúrgica. Um alto índice de suspeição é necessário para o correto diagnóstico. The authors report one case of a 57-year-old woman who for many years had a unilateral nasal obstruction; purulent rhinorrhea and chronic infection both caused by rhinolithiasis. The disease most frequently seen in association with rhinolithiasis is chronic sinusitis. The rhinolithiasis is a calcareous concretion formed in layers visible by X-rays. The rhinolith was discovered incidentally in some patients. Rhinoliths are rare and can have various clinical presentations. The treatment of choice is surgical removal. A high index of suspicion is required for the diagnosis of such a forgotten entity. Rev Bras Otorrinolaringol.
