Les carcinomes canalaires de la parotide

Abstract

PurposeTo describe the clinical, therapeutic and prognostic features of ductal carcinomas of the parotid gland. Material and methodsFive patients with ductal carcinoma of the parotid gland (primary and secondary carcinoma) treated, between 2007 and 2019, in our ENT department, were reviewed. ResultsFour men and one woman were included. The mean age was 61,4 years. One patient had a history of an invasive ductal carcinoma of the breast. Four patients consulted for swelling in the parotid region. One patient referred to our department for dysfunction of facial nerve. Skin invasion was found in one case. Four patients underwent total parotidectomy with sacrifice of the facial nerve (three cases). One patient underwent extended parotidectomy involving the skin. An ipsilateral selective neck dissection was performed in four cases. One patient had a parotid gland biopsy. Ductal carcinoma was primary in four cases and metastatic from breast origin in one case. Four patients were treated with postoperative radiotherapy. Remission was obtained in three cases. One patient had a local and meningeal recurrence. The patient with metastatic carcinoma had pulmonary, bone, hepatic and brain progression. ConclusionDuctal carcinoma is a rare and aggressive tumor of the parotid gland. It can be primary or secondary. The treatment is based on surgery and radiotherapy. The prognosis is poor.
