title: Non-epithelial neoplasms of the larynx and hypopharynx - 12 - years of experience.
abstract: OBJECTIVE
  The non-epithelial neoplasms of larynx and hypopharynx are of rare incidence but may originate from various histological tissues. These effect in the difficulty of final diagnosis and often delay the proper treatment.
  
  
  METHODS
  There was performed retrospective analysis of patients with histopathologicaly confirmed non-epithelial neoplasms of larynx or hypopharynx between 2001 and 2013, that included the evaluation of epidemiology, diagnostic methods and treatment.
  
  
  RESULTS
  Non-epithelial neoplasms of larynx and hypopharynx were established in 18 patients (9 women, 9 men), mean age - 60,3 years. The malignant neoplasms were diagnosed in 10 patients and benign - in 8. The soft tissue neoplasms were the most common - 8 patients. There were also 4 lymphomas, 4 chondrosarcomas, 1 paraganglioma and 1 malignant melanoma. Tumors manifested clinically as covered by unchanged mucosa. Characteristic features were observed on computed tomography for certain cases of these neoplasms. The results of the tumor biopsy were in most of the cases not diagnostic. Intralaryngeal microsurgery was applied in benign neoplasms, chemiotherapy - for lymphomas and total laryngectomy for chondrosarcomas and malignant melanoma.
