Both masses histologically appear as islands or cords of squamous epithelium invading the connective tissue stroma irregularly with palisades of basal cells. However, human peripheral ameloblastoma does not invade bone. ameloblastoma include the follicular, acanthomatous, plexiform, granular cell, basal cell and desmoplastic [ 3].
