Puzzling case of parotid tumor:

This ultrasound and Color Doppler video clip of a right parotid tumor in a middle aged male patient shows the diagnostic dilemma in arriving at an exact pathological diagnosis. This tumor shows characteristics of both Warthin's tumor as well as pleomorphic adenoma. Sometimes, only the pathologist can make the "final diagnosis". What is apparent is that this is a benign mass of the parotid, with a higher likelihood of it being a Warthin's tumor.
