Massive Multinodular Head and Neck Recurrence of Parotid Gland Pleomorphic Adenoma : A Case Report

الملخص EN

Introduction.

The optimal initial management of parotid pleomorphic adenomas reduces the risk of recurrence and malignant transformation.

Surgery of recurrence can be difficult in multinodular disseminated forms.

Case Report.

A 67-years-old patient was referred for management of a large multifocal recurrence of a pleomorphic adenoma operated on 23 years ago.

The clinical and radiological assessment found parapharyngeal, infratemporal, and prestyloid invasion, with nodules in the sternocleidomastoid muscle.

Excision by transmandibular approach was performed.

The pathologist found a multinodular recurrent pleomorphic adenoma without criteria of malignancy.

Postoperative radiotherapy was performed.

Discussion.

Multinodular forms and incomplete resections are the most important factors that are thought to predispose to recurrence.

A precise analysis of the extension by preoperative MRI is essential.

Adjuvant radiotherapy can be given in these recurrent multifocal forms.
