Ultrasonographic and sonoelastographic features of pleomorphic adenomas of the salivary glands. This study aimed to investigate the utility of the apparent diffusion coefficient (ADC) value, texture features, and their combination for the differential diagnosis of parotid gland tumors. Many types of parotid malignancies exist, most arising from the epithelial elements of the gland. Sebaceous carcinoma is a rare parotid malignancy that often presents as a painful mass. This procedure is appropriate for malignancies confined to the superficial lobe, those that are low grade, those less than 4 cm in greatest diameter, tumors without local invasion, and those without evidence of regional node involvement.
