Synchronous double primary cancers of the unilateral parotid gland.
Synchronous parotid neoplasms, especially synchronous neoplasms of two separate and histologically different types, are extremely uncommon. A review of the literature revealed that most reported cases were either a combination of two distinct benign neoplasms or a benign neoplasm and another malignant tumor. To the best of our knowledge, there has been no report of synchronous unilateral double primary carcinomas of the parotid gland. Here we report a 39-year-old woman who exhibited basal cell adenocarcinoma and mucoepidermoid carcinoma simultaneously in the left parotid gland.
