title: Clinicopathologic study of parapharyngeal tumors.
abstract: BACKGROUND
  Parapharyngeal space (PPS) tumors are rare. Three main groups are identified, namely those of salivary origin, neurogenic tumors and paragangliomas. Early pathological classification of PPS tumors is important for pin point diagnosis and timely management.
  
  
  OBJECTIVE
  The PPS is a complex anatomical potential space and poses high risk of per and postoperative complication. This study was done to perform optimum preoperative evaluation by clinicoradiologic correlation and guided fine needle aspiration cytology (FNAC) which is essential to minimize intraoperative risk.
  
  
  METHODS
  Guided FNAC was carried out to diagnose parapharyngeal tumors in 48 patients from January 2008 to January 2010. The inflammatory lesions were excluded in the present study. Correlation with histopathology was done in all the cases.
  
  
  RESULTS
  The mean age for all the patients was 38.2 years. There were 23 male and 25 female subjects. Seventy nine percent of the lesions were benign with pleomorphic salivary adenoma being the commonest, while only 20.8% of the lesions were malignant. All the patients presented with neck swelling. No complication was encountered in the present study.
  
  
  CONCLUSIONS
  FNAC can replace incisional biopsy which may be hazardous in this area. Immediate treatment can be planned based on the FNAC report.
