Adenomatoid dentinoma. Report of four cases of an unusual odontogenic lesion.
Four cases of a rare odontogenic lesion are reported. In each of the 4 examples, the lesion manifested itself as a well-circumscribed unilocular radiolucency in the mandibular third molar region in an adult. The histopathologic features consisted of an encapsulated proliferation of odontogenic hard and soft tissues. The hard tissue component consisted of dentin deposited in a peripheral ringlike configuration that enclosed odontogenic epithelium resembling adenomatoid odontogenic tumor. Whether this process represents a neoplasm or an odontogenic hamartoma is an unresolved question. Treatment in each case consisted of curettage, and no recurrences were observed.
