Three cases of monomorphic adenomas (two oncocytic adenomas and one basal cell adenoma) of the parotid gland are reported. The diagnosis is based on echography with fine needle biopsy and cervical computerized tomography. Because of the high percentages of multicentricity, the therapy of choice is superficial parotidectomy when the lesion is in the pre-neural lobe of the gland, or total parotidectomy in case of a deep mass.
