![]() 92.1 % of lesions were benign with Warthin tumor being the most common diagnosis followed by pleomorphic adenoma. The average size of the parotid lesions was 1.5 cm and 91 % were located in the superficial lobe. The average age was 67.5 years and 92 % were males. We evaluated the patient demographics and pathological diagnoses of sampled parotid lesions to determine the histopathological spectrum and risk of malignancy. The histopathologic findings of all sampled lesions were reviewed. This retrospective chart review included 89 lesions in 87 patients with asymptomatic parotid lesions discovered on cross-sectional imaging studies performed for unrelated clinical indications. Over a 10-year period, 154 patients underwent 163 ultrasound-guided parotid lesion biopsies at our institution. ![]() The purpose of this study is to determine the histopathological spectrum and risk of primary malignancy of asymptomatic parotid lesions incidentally discovered on cross-sectional imaging.
