Abstract

Introduction:  Ductal carcinoma is one of the rarest and most aggressive parotid tumors.

The observations.

Case 1: A 69-year-old female patient was referred for ductal carcinoma of the left parotid gland. The treatment was surgical (parotidectomy with ipsilateral selective cervical dissection) with capsular rupture and with healthy margins, which led us to perform postoperative radiotherapy (60Gy). The patient was in recurrence-free survival after seven years of monitoring.

Case 2: a 70-year-old patient was referred for ductal carcinoma of the left parotid gland. Parotidectomy with ipsilateral selective cervical dissection left healthy but insufficient margins (<1 cm), which led us to perform postoperative radiotherapy (70 Gy). After eight years of monitoring, the patient was surviving without recurrence.

Discussion: The mean age found in the cases published in the literature was 60 years. The sex ratio was two men for one woman. The five-year recurrence-free survival rate was 34% on average. Conclusion. Surgery is the main treatment for this type of cancer. Postoperative radiotherapy is indicated in the event of extra parotid tumor extension, if the resection margins are not healthy, in the event of cervical lymph node metastasis and in the event of lymphatic emboli and / or nerve invasion. Chemotherapy is generally reserved for metastatic forms.
