|
Background and Objectives: The majority of laryngeal tumors are known to be squamous cell carcinoma. Non-squamous cell tumors of the larynx represent various specturm of disease with different prognosis and rationales of managememt from
squamous
cell carcinoma. Therapeutic options to these tumors depend on their histopathological characteristics and clinical behavior. To assess the unique aspects of the non-squamous cell tumors which can lead to their diagnosis and to provided
considerations of
managment options and prognostic variables. Materials and Methods: Eight non-squamous cell tumors of the larynx including 6 malignant tumors (two malignant lymphoma, single instances of adenoid cystic carcinma, malignant schwanoma,
osteoscoma,
and spindle cell carcinoma) and two benign tumor (hemangioma, spindle cell lipoma) during the 7-year period from 1990 to 1996 were reviewed retrospectivly. Results: The frequently presenting symptoms were hoarseness, dyspnes, sore throat,
and
lump sensation in the throat. The most common origin site was supraglottis(50%), followed by glottis (38%) and subglottis (12%). All non-squamous malignancies beside non-Hodgkin's lymphoma were treated by surgery and postoperative radiotherapy.
Two
benign tumors were treated with only surgery. The mean follow-up period was 37.4 months and all patients have survivied with no evidence of recurrence. Conclusion: Our experience suggests that non-squamous cell tumors are a group of
various
pathological types and it may be possible to achieve better results with combined treatment including surgery.
