Recurrent Pleomorphic Adenoma of the Parotid Gland: A Prospective Histopathological and Immunohistochemical Study

Abstract

The extended multifocal distribution of tumor recurrences after insufficient resection of pleomorphic adenoma (most often after enucleation) can explain a high incidence of further recurrences. Therefore, a total parotidectomy including removal of surrounding fat tissue seems to be appropriate for the initial treatment of recurrent pleomorphic adenoma.
