A case of mixed tumor of the parotid gland presenting as a retroauricular mass was located at the lower end of a mastoidectomy scar. Complete removal of the tumor which was contiguous with the parotid gland was effected with special care to identify the facial nerve. Mixed tumors of the parotid gland should be considered in the differential diagnosis of all postauricular mastoidectomy incision site tumors.
