[Recurrent benign tumors of the parotid gland and their tendency for becoming malignant].
In 257 parotid adenomas lumpectomy led to tumour recurrence in 49.2%, superficial parotidectomy in 5.7% and total parotidectomy in 5.3%. 40 patients with recurrent tumours experienced eventually eight true malignant neoplasms. There were five carcinomas ex pleomorphic adenomas, one true malignant mixed tumour, and two undifferentiated carcinomas. Malignant transformation usually occurred with the 4th recurrence after 15.8 years. To prevent recurrence and secondary malignancy in parotid adenomas the lumpectomy technique should be omitted.
