Synchronous Ipsilateral Double Primary Carcinomas of the Parotid Gland: A Case Report / 대한이비인후과학회지

ABSTRACT

Synchronous parotid neoplasms are rare cases. In particular, a synchronous neoplasm of two histologically different types is extremely unusual. A review of other references show that most cases of synchronous neoplasms are compounds of two distinct benign neoplasms or that of one benign neoplasm and other malignant tumor. To date, there are no reports about synchronous unilateral double primary carcinomas of the parotid gland. Here, we report a 39-year-old woman who developed the basal cell adenocarcinoma and the mucoepidermoid carcinoma simultaneously in the left parotid gland.
