The purpose of this study was to offer pathological reasons for partial parotidectomy adopted in parotid pleomorphic adenoma treatment. Continuous slices from 25 cases of primary parotid pleomorphic adenoma were carefully examined and the extra-envelope infiltration, the budding and the primary multi-center were measured and recorded. The range of extra-envelope infiltration and budding was limited in 0.09-0.285 mm out of tumor capsules, which was far less than the safe boundary(1 cm) of the partial parotidectomy. Two cases with multi-centers were found, but all the centers were aggregated together and encapsulated in a united envelope. Partial parotid parotidectomy is a safe method and can remove the tumor completely in parotid plemorphic adenoma treatment.
