[Pindborg tumor: a poorly differentiated form without calcification].
BACKGROUND
Pindborg tumor is a rare benign epithelial calcified odontogenic tumor. Radiological diagnosis is generally suspected because of the presence of calcifications.


METHODS
A 61-year-old man presented a polymorphous Pindborg tumor of the anterior maxillary. The diagnosis was hindered due to the nonspecific radiographic image and the lack of calcification. Pathology provided the positive diagnosis of poorly-differentiated young odontogenic epithelial tumor.


CONCLUSIONS
Pindborg tumor is a rare lesions usually found in the posterior mandibular bone. Calcification is a characteristic feature. There are two historical forms, a squamous form with very favorable outcome and a clear-cell form with less favorable prognosis.
