الوصف: CONTEXT: The minimal recommended surgical approach to parotid tumors is partial parotidectomy with resection of the superficial lobe of the gland. Histologic diagnosis prior to surgery is not possible, as incisional biopsies are contraindicated due to the possibility of facial nerve injury or incomplete tumor resection. Thus, the biopsies tend to be perioperative. OBJECTIVE: To compare the results of frozen section examination with the definitive pathological diagnosis. DESIGN: Accuracy study by retrospective analysis. SETTING: Head and Neck Surgery Service of Heliópolis Hospital, São Paulo, Brazil. SAMPLE: 153 cases of parotid gland tumors treated between 1977 and 1994. DIAGNOSTIC TEST: Frozen section and pathological diagnosis. MAIN MEASUREMENTS: Sensibility and specificity of the frozen section examination. RESULTS: Frozen section study diagnosed 19 (12.4%) malignant and 127 (83.7%) benign tumors. Sensitivity of the frozen sections for malignancy was 61.5% (95% CI 54 to 69%) and specificity was 98% (95% CI 94 to 100%), and this result is comparable to the literature. CONCLUSIONS: We consider that frozen section examination for salivary gland tumors is not sufficient on its own for deciding on the best management. Their interpretation must be correlated with clinical and intraoperative findings, in association with the surgeon's experience.

الوصف: CONTEXT: Lingual thyroid gland is a rare clinical entity that is caused by the failure of the thyroid gland to descend to a normal cervical location during embryogenesis. The occurrence of an ectopic thyroid gland located at the base of the tongue may cause problems for the patient, with symptoms of dysphagia, dysphonia, upper airway obstruction or even hemorrhage at any time from infancy through adulthood. CASE REPORT: We report on a case of lingual thyroid gland in a 41-year-old female patient. The embryology and diagnosis of ectopic thyroid are discussed and its management is outlined. Features of the diagnostic and therapeutic evaluation are described with attention to the clinical findings, laboratory tests, thyroid scan and computed tomography imaging studies employed in the confirmation of diagnosis and planning of appropriate treatment. The history of the condition is reviewed and a treatment strategy is outlined. Surgical excision of the gland is reserved for cases of gland enlargement that result in compromised airways (dysphagia or dysphonia) or recurrent hemorrhage.

مصطلحات موضوعية: Parapharyngeal Space Tumors, Head and Neck Tumors, Parapharyngeal Neoplasms, Head and Neck Surgery

الوصف: CONTEXT: Parapharyngeal space tumors comprise less than 0.5% of all head and neck neoplasms.1 The majority of these tumors are benign, but surgery is usually required to establish the diagnosis and treat the patients. We present 26 patients treated surgically for tumors arising in the parapharyngeal space (PPS) at the State University of Campinas Hospital – UNICAMP. CASES SERIE: Of these, 17 (65.5%) had benign and 9 (34.6%) malignant neoplasms. The surgical and pathological data relevant to these cases are highlighted, observing any local recurrence, surgical complications and the five-year survival. Neurogenic tumors and soft tissue sarcomas were, respectively, the most frequent benign (35.3%) and malignant neoplasms (44.5%). Benign tumors accounted for the majority of the cases and involved minimal surgical morbidity with no recurrence during a median follow-up of five years. Malignant tumors had a high rate of recurrence and mortality. Surgery is the treatment of choice for PPS tumors. A knowledge of the anatomy of this site is essential for the safe performance of surgical procedures. Malignant neoplasms have a poor prognosis. Fine needle aspiration was helpful in diagnosis of all tumors.

CONTEXTO: Tireóide lingual é uma entidade rara, devida a falha na migração da glândula em sua fase embriogênica. A presença da glândula tireóide na base da língua pode acarretar sérios problemas aos pacientes, como disfagia e disfonia, obstrução de vias aéreas superiores e até hemorragia, em qualquer fase da vida. RELATO DE CASO: Apresentamos um caso de tireóide lingual em paciente de 41 anos de idade, discutindo-se a embriogênese, diagnóstico e conduta adequada para tratamento. Elementos para o diagnóstico e avaliação terapêutica são descritos com especial atenção aos achados clínicos, testes laboratoriais, além de metodologia de imagem como medicina nuclear e tomografia computadorizada, realizados para confirmação diagnóstica e planejamento da melhor conduta operatória. A excisão cirúrgica da tireóide ectópica é reservada para casos de aumento glandular, que podem resultar em disfunção das vias aéreas superiores (disfonia ou disfagia), além de hemorragia recorrente.
