Dentigerous cyst is a fairly common odontogenic cyst with an uncomplicated prognosis. However, reports of odontogenic and non-odontogenic tumors arising from the cysts have been published for many years. Therefore, the importance of thorough histopathological examination and regular follow-up cannot be overemphasized. Here is a case report of a possible development of desmoplastic ameloblastoma from a dentigerous cyst. This case is unique for two main reasons. Firstly, to our knowledge such a case has not been reported previously. Secondly, the tumor seemed to arise from the capsule and not from lining of the dentigerous cyst. Transformation of odontogenic rests into cysts is known to occur in the syndromic cases of odontogenic keratocysts (resulting in recurrent and daughter cysts) but not in dentigerous cysts. This case report may prompt greater interest in the role of the supposedly inactive odontogenic nests in the capsule of these cysts.
