Huge pleomorphic adenoma of the parotid gland: report of a case

ABSTRACT

Pleomorphic adenoma of the parotid gland typically presents as painless, mobile mass of long duration, and originate in the superficial lobe but, more rarely these tumors may involve the deep lobe of the parotid gland. The average size of a parotid neoplasm is 2 to 4 cm. The effective treatment of parotid pleomorphic adenoma is surgical excision. The simple excision or enucleation resulted in recurrence rate of 45% in benign tumor. Therefore, the superficial parotidectomy with identification and preservation of the facial nerve is now the most widely accepted surgery. We report a case of the huge pleomorphic adenoma of the left parotid gland in a 67-year-old man who complained the large mass, measured about 10x7x5 cm-sized, in front of the left ear and on the mandibular ascending ramus. The diagnosis was confirmed by the clinical examination, computed tomographic scan, fine needle aspiration, and incisional biopsy. Superficial parotidectomy including the tumor and preservation of the facial nerve using the modified Blair approach was performed. And satisfactory results have been obtained cosmetically and functionally.
