This tumors is an isomorphic epithelial tumor of salivery gland, characteristic of absence of myoepithelial cells which are present in pleomorphic adenoma and other salivery gland tumors. Clinicopathologically the tumors is very difficult to differentiate with pleomorphic adenoma or adenoid cysticㆍcarcinoma. The prognosis is excellent by complete extirpation of the tumor. The present report presents two cases of basal cell adenoma of the parotid gland seen in 63 year old man and 71 year old man in one-year period at Department of Surgery, Yonsei University College of Medicine.
