Objective: Salivary gland tumors are a heterogenous group of lesions with variable pathology and clinical outcomes. Most published data are derived from studies conducted at tertiary care centers. Our study analyzed the experience from a community setting to determine significant differences, if any, in pathological distribution and clinical outcomes compared to the existing literature. Methods: We performed a retrospective analysis of all major salivary gland tumors that presented to a large community practice over a 20 year period. Retrospective chart analysis was performed for demographics, clinical presentation, imaging, cytology, histopathology, and clinical outcome data. Results: Of 806 patients, the parotid gland was the most common site in 683 patients (84.7%), followed by submandibular in 78 (9.7%) and sublingual in 45 (5.6%). A total of 203 patients were managed conservatively with observation without definitive diagnosis or lost to follow-up. A total of 495 patients underwent surgical intervention within the community practice. Twenty-six patients underwent surgical excision at an outside hospital. Eighty-two patients were determined to have a benign diagnosis based on ultrasound-guided fine needle aspiration or excisional biopsy alone. Final histopathology was benign in 505 cases (83.7%), while 98 tumors (16.3%) received a diagnosis of primary or secondary malignancy. For the parotid gland, pleomorphic adenoma (155) and Warthin’s tumor (155) were the most common benign diagnoses, while mucoepidermoid carcinoma (13), adenocarcinoma (8), and acinic cell carcinoma (8) were the most common primary malignancies. Conclusions: We found a higher rate of benign tumor pathology compared to the existing literature. While the outcome data on surgical treatment of benign tumors are comparable to the existing literature, the same conclusion cannot be drawn for malignant tumors, given relatively small numbers in our series and likely disparity in the complexity of the surgical cases in tertiary care centers.
