A Report of 4 Laryngeal Sarcoma Patients
نویسندگان
چکیده
Sarcomas account for a very small percentage of the head and neck malignancies in adults Laryngeal sarcomas represent 1% of all laryngeal malignancies. Chondrosarcoma is the most common laryngeal sarcoma, and originates mostly from the cricoid cartilage. Less than 3% of all cervicocephalic rhabdomyosarcomas is located in the larynx and laryngeal rhabdomyosarcoma is characterized by less aggresive spread than other rhabdomyosarcomas. Pleomorphic variant of rhabdomyosarcoma is usually encountered in adults. Laryngeal sarcomas have different prognosis and treatment approaches than squamous cell cancers. In this presentation, we discussed the clinical and histopathological features of four laryngeal sarcoma cases; which 2 were diagnosed as chondrosarcoma of arytenoid and cricoid cartilage, and 1 was as spindle cell rhabdomyosarcoma originating from aryepiglottic fold, and 1 pleomorfic variant of rhabdomyosarcoma.
