Although @entity5 of mesenchymal origin ( @entity242 , @entity8433 ) are extremely rare (1% of all @entity5 ), the histological manifestations are very diverse. @entity8433 sign as a solid @entity5 covered with an intact mucosa. THE AIM OF THE STUDY: was to evaluate retrospective data referring: epidemiology, clinical manifestations, treatment and early follow-up; based on medical record made in ORL, HNS Surgery Dpt of Holy @entity5 Centre in Kielce during 9-years period 2001-2009. MATERIAL AND METHODS: The retrospective analysis of the group of 12 @entity1 with @entity8433 was made. Studied characteristics were: age, sex, primary focus, histological outcome, treatment options and early follow-up. RESULTS: Age of the group of 12 studied @entity1 (10 M, 2 F) ranged from 48 to 84 (mean 69.8). @entity8433 accounted 1.2% (12/935) for all of @entity5 . The focus of origin were: glottis (6), @entity2582 (5); subglottis (1). The most common histological types of @entity8433 at studied group were: neurosarcoma (2), @entity1492 (2), @entity6872 (2), @entity511 (1), @entity1418 (1), @entity242 low grade (1), @entity706 (1), @entity1821 (1) and haemangioendothelioma epithelioides vel @entity6872 (1). Methods of treatment were: surgery (6); radiotherapy (1); chemotherapy (1); chemo- and radiotherapy (3); symptomatic treatment (1). The clinical results of treatment are: 9 @entity1 are still alive (5 pts more than 5 years, 3 pts less than 5 years, 1 pts less than 2.5 years with @entity66 ); 3 @entity1 died: 2 pts in 1st year from diagnosis, 1 pts after 3 years of treatment died of non-oncological causes. CONCLUSIONS: 1. @entity8433 are extremely rare and diversed histologically. 2. Immunochemical analyses are very important procedures used in diagnostics of these @entity5 . 3. An individual approach is needed in diagnostic and therapeutic procedures of @entity8433 .
