Abstract
BACKGROUND
The presence of synchronous benign and malignant salivary gland neoplasms is very rare. The authors present a previously unreported combination of Secretory Carcinoma (SC) and Warthin's Tumor (WT) within the same parotid gland.
METHODS
The patient presented with increasingly painful enlargement of the left parotid gland. CT scan with contrast revealed a heterogeneous solid/cystic mass in the superficial lobe. Fine needle aspiration cytology favored pleomorphic adenoma (PA) and patient underwent superficial parotidectomy without complication.
RESULTS
Final pathology revealed concomitant presence of SC and WT. Stains were positive for S100 and mammaglobin, and FISH revealed the presence of t(12;15) (p13;q25) translocation, resulting in the ETV6-NTRK3 fusion gene.
CONCLUSION
It is important for surgeons and pathologists to note the potential for co-existing benign and malignant pathology within the same salivary gland, as this can have an impact on management and prognosis for patients.
