Combined epithelial odontogenic tumor: adenomatoid odontogenic tumor and calcifying epithelial odontogenic tumor.
1. Two cases of a combined epithelial odontogenic tumor which had areas of AOT and CEOT were presented. 2. A review of the studies on histogenesis of the AOT revealed that the tumor probably consists of preameloblasts, stratum intermedium, and stellate reticulum. 3. A review of the studies on histogenesis of the CEOT revealed that the probable origin was in cells of stratum intermedium. 4. It is suggested that the present cases support the aforementioned theories of histogenesis and represent AOT's which contain foci of CEOT. 5. The suggested treatment is simple surgical excision.
