Mukoepidermoides Karzinom des Larynx. Fallbericht und Literaturübersicht

Abstract

Das mukoepidermoide Karzinom (MEK) gehört zur Gruppe der SpeicheldrUsentumoren und ist am häufigsten in der Glandula parotis lokalisiert. Laryngeale Manifestationen sind selten. Bisher wurden in der Literatur 87 Fälle beschrieben. Wir berichten em MEK der rechten Stimmlippe eines 75jährigen Mannes, weiches initial fir em Plattenepithelkarzinom gehalten wurde. Em Jahr nach erfolgter Strahlentherapie mit 70 Gy entwickelte sich em Tumorrezidiv. Da der Patient die Laryngektomie ablehnte, wurde der Tumor in der Folgezeit zweimal mit dem C02-Laser reseziert. Der Patient ist jetzt 5 Jahre rezidivfrei. Die Inzidenz der laryngealen MEK ist moglicherweise höher als bisher angenommen, cia sic oft als Plattenepithelkarzinome fehldiagnostiziert werden. Mucoepidermoid Carcinoma of the Larynx-Case Report and Review of the Literature Mucoepodermoid carcinoma (MEC) is classified among the salivary gland tumours and is most commonly found in the parotid gland. It rarely occurs in the larynx. There have been only 87 cases of laryngeal MEC reported in the literature. We report on an MEC of the vocal cord in a 75-yearold man, with a thickened right vocal cord without any loss of movement. The initial diagnosis was squamous cell carcinoma. One year after radiotherapy a tumour recurrence developed. Because the patient refused to laryngectomise, a tumour resection with the CO2 laser was performed twice. To date, the patient has been free from disease for more than five years. The true incidence of this type of neoplasm could be higher than is believed because of its frequent misdiagnosis as squamuos cell carcinoma.

Surgical Removal of a Huge Epiglottic Lipoma: Case Report

“…Several subtypes of lipoma have been observed. They include fibrolipomas, myxolipomas and angiolipomas [5].…”

“…Surgery is the treatment of choice and includes endoscopic techniques, microscopic laryngeal surgery and external surgical approach (cervicotomy) [8] [9] [10]. Instead of microscopic surgery, macroscopic surgery has been a management of choice to approach huge epiglottic tumors via external cervical incisions since the size of tumor restricts visualization of the operating field under the endoscope or microscope [5] [11]. However, a standard surgical management for large lipomas of the epiglottis has not been present yet [8].…”

Estudo retrospectivo de 698 cistos de cabeça e pescoço diagnosticados no laboratório Anatom em Cascavel - PR no período de 2004-2013

“…Deve-se analisar o diagnóstico diferencial com: higroma cístico, sendo este uma malformação do sistema linfático na região do pescoço e está localizado atrás do músculo esternocleidomastoideo; tumor da glândula tireóide localizado dos lados da traqueia em nível das cordas vocais; lipomas e cistos sebáceos (Lippert et al, 2002). Wong et al (2008) realizaram uma extensa revisão dos métodos de diagnóstico das lesões em pescoço.…”
