Desmoplastic ameloblastoma

The ameloblastoma is a true neoplasm of enamel organ-type tissue which does not undergo differentiation to the point of enamel formation, and the term 'adamantinoma' which implies the formation of hard tissue was replaced by 'ameloblastoma' since these tumor is not associated with the formation of hard tissue (1) Recently experienced a case of ameloblastoma which could not be explained by any of the known bone destruction patter ns of ameloblastoma. Rather the lesions looked like a fibro-osseous lesion. The result of biopsy was quite storage not only to the radiologists but also to the surgeons who operated the lesion. The suspicion could only be explained by finding a report (2) by Japanese who experienced a similar case.
