• Thirty cases of pleomorphic adenoma, treated and histopathologically proved in our department between October 1981 and September 1991, were reviwed and clinically analyzed. The patients included 8 men and 22 women, whose ages ranged from 16 to 75 years old with a mean of 46.0. Twenty-four cases were distributed in the minor salivary glands (80.0%) and 6 cases in the major salivary glands. Among the minor salivary gland lesions, the locations were the palate in 17 cases (56.7%), the buccal mucosa in 3 (10.0%), the lip in 3 (10.0%) and the tongue in 1 (3.3%) . In the major salivary gland lesions, 4 cases (13.3%) were found in the submandibular gland and 2 cases (6.7%) in the parotid gland. The pathologic diagnoses were pleomorphic adenoma in 27 cases (90.0%) and carcinoma in pleomorphic adenoma in 3 (10.0 %) . All cases of the carcinoma in pleomorphic adenoma occurred in the minor salivary glands; the palate, buccal mucosa and lip. Despite benign appearance, these cases were consequently diagnosed as carcinoma in pleomorphic adenoma, and chemotheraphy was employed postoperatively.<BR>All the lesions in the series were surgically removed, followed by histopathologic examinations. All cases including carcinoma in pleomorphic adenoma have showed no evidence of recurrence to date. In conclusion, precise histopathologic examination is required even with benign appearance in the treatment of salivary gland tumors.
