Immunohistochemical Characterization of Combined Adenomatoid Odontogenic Tumor and Calcifying Epithelial Odontogenic Tumor - Report of 3 Cases and Review of the Literature -
Combined epithelial odontogenic tumors are very rare and represent hybrid lesion comprising adenomatoid odontogenic tumor intermixed with calcifying epithelial odontogenic tumor. The authors present 3 cases of combined epithelial odontogenic tumor which contained diagnostic areas for both adenomatoid odontogenic tumor and calcifying epithelial odontogenic tumor. Their behaviour and histogenesis were discussed.
