Bilateral Basaloid Squamous Cell Carcinoma of the Parotid Gland: A Case Report and Review of the Literature.
We describe the first known case of bilateral basaloid squamous cell carcinoma of the parotid gland, and we review existing literature.



A previously healthy, 70-year-old white man presented with a 2-cm enlarging mass in the tail of the right parotid gland. Magnetic resonance imaging and computed tomography showed ipsilateral pathologic adenopathy. Results of fine-needle aspiration revealed a high-grade malignancy with squamous features. The patient underwent a right total parotidectomy and modified radical neck dissection. Final pathologic findings revealed a basaloid squamous cell carcinoma. Four years after the initial resection, the patient presented with an enlarging left parotid mass. Findings of fine-needle aspiration and imaging were similar to those 4 years earlier. The patient received a left total parotidectomy and modified radical neck dissection. Postoperative radiation therapy was performed after each surgical intervention. He remains disease free at 4-year follow-up after the second mass was resected.



Squamous cell carcinoma with basaloid features is a rare and aggressive type of squamous cell carcinoma. To our knowledge, this is the first case report of bilateral parotid basaloid squamous cell carcinoma.
