We reviewed and clinically analyzed 31 cases of pleomorphic adenoma treated at our hospital between 1978 and 1992. These cases (9 males and 22 females) ranged in age from 19 to 80 years old with a mean age of 44.7 years. There were 20 cases with adenoma in the parotid gland (64.5%),7 cases in the submandibular gland (22.6%), and 4 cases in the minor salivary glands (12.9%). The chief complaint was tumor palpation.
Spontaneous pain and tenderness were found in a few cases. Ultrasonics, scintigraphy, computed tomography and magnetic resonance imaging were useful for preoperative diagnosis, with ultrasonography, in particular, showing more characteristic findings than other methods.
The adenoma in 30 cases was surgically removed. One case was diagnosed as a malignant mixed tumor by aspiration biopsy and only radiotherapy was performed. All cases were followed by histopathologic examinations, but there were no case diagnosed as carcinoma in pleomorphic adenoma. There were no cases of recurrence or malignant change. In conclusion, complete removal in the initial surgery, precise histopathologic examination and long-term follow-up are required in the treatment of pleomorphic adenoma.
