Recurrent pleomorphic adenoma of the parotid.
Nineteen patients with recurrent pleomorphic adenoma of the parotid are reported. The aetiology of recurrence is discussed and capsule rupture is emphasized as a major cause, especially of multinodular recurrence. Further surgical attempts to remove recurrences are justified by the possibility of misdiagnosis of the original tumour and the late development of malignancy in recurrent nodules. Tumour clearance was achieved in all but two of 19 patients with recurrence or incomplete primary excision in those in whom it was attempted. Radiotherapy does not seem to be an appropriate alternative to repeated surgical excision.
