Abstract

The authors reported an unusual example of an adenomatoid odontogenic tumor arising from a dentigerous cyst,which had been recurred 2 years following an enucleation.Microscopic examination revealed the presence of an adenomatoid odontogenic tumor components direct continuity to the lining epithelium of a dentigerous cyst. It would be seemed that this tumor was derived from the reduced enamel epithelium of post-secretory ameloblasts.Adenomatoid odontogenic tumor is entirely benign, encapsulated lesion. No aggressive behavior of this tumor has been described, and recurrences are very rarely observed. In this case, there was an tumor islands in the fibrous connective capsule.It assumed that the presence of tumor components in the capsule might be a primary cause of recurrence. However, the possibility of an inadequate surgical intervention could not be completely excluded.Therefore,meticulous follow-up evaluation is necessary in the event of the presence of tumor islands in the tumor capsule.
