Subtotale Krikoidresektion als primäre Therapie eines hochdifferenzierten Chondrosarkoms des Ringknorpels

Abstract

Chondrosarcomas of the larynx are rare malignant tumors usually diagnosed with significant delay due to their nonspecific symptoms. We report a 50-year-old male presenting with progressive dyspnea. Indirect laryngoscopy revealed a subglottic stenosis. The cricoid cartilage was shown on CT to be massively damaged. Histologic differentiation between chondroma and highly differentiated chondrosarcoma was very difficult. Therefore, an organ-preserving treatment concept using partial cricoid resection and staged endoscopic arytenoidectomy was chosen. Total laryngectomy and permanent tracheostomy could be avoided. Due to the risk of recurrence, early follow-up with endoscopy and CT is mandatory.

Laryngeal Chondrosarcoma with Unusual Dissemination to the Humerus

“…In case of early diagnosis and highly differentiated (G1) lesions, an organ-preserving treatment concept is often possible [7]. The resection margins and surgical technique are defined by the location and extent of the lesion.…”
