PLEOMORPHIC ADENOMA IN PARAPHARYNGEAL SPACE – A CASE REPORT AND REVIEW LITERATURE

Abstract

INTRODUCTION Parapharyngeal tumours account for 0.5% of all head and neck masses and vast majority are b e n i g n . P l e o m o r p h i c a d e n o m a s o f t h e parapharyngeal space arise from the deep lobe of parotid gland present in oropharynx. MATERIAL AND METHOD A case of benign tumor of Parapharyngeal Space was admitted in the Otorhinolaryngology department of a tertiary care centre. The patient was a 26yr old female presented with chief complaints of difficulty in swallowing and swelling in the oral cavity since 2 months. On examination there was a firm swelling on right submandibular region and upper side of neck and uvula was deviated towards left side. CTscan revealed a heterogenous mass in the parapharyngeal space. Provisional diagnosis of benign salivary gland tumor of the parapharyngeal space was made. Tumour was surgically excised and tissue send for histopathological examination, which confirmed the tumour as Pleomorphic adenoma. CONCLUSION Pleomorphic adenoma in parapharyngeal space is of rare occurrence. An adequate clearance of the tumor with a cuff of surrounding dispensable normal tissues is the key to successful treatment of such tumors. Keywords: Pleomorphic Adenoma; Parapharyngeal Space;
