We herein report a rare case of extraosseous calcifying epithelial odontogenic tumor with local aggressive behavior. CT and MR imaging showed the distinctive appearances of this histologic entity. We briefly discuss the radiologic features of calcifying epithelial odontogenic tumor and the relevant literature.

Introduction: Cysts of the jaw are a recognized clinical entity for a long time and are a benign bone destroying lesion. Their remains a diagnostic ambiguity between cysts and cyst-like lesions of the jaws. Objective: The main objective of this study was to assess the total soluble protein content in fluid aspirates of intra osseous cyst of maxilla and mandible. Materials and Methods: A total n...

Although aneurysmal bone cysts and calcifying odontogenic cysts accompanied with other lesions are reported in the literature, the simultaneous occurrence of these two distinct lesions has not been reported. To the best of our knowledge, this is the first report describing co-occurrence of these two lesions located in the left mandibular ramusin a 36-year-old woman.      

objective: the ortho keratinized odontogenic cyst (ooc) is a rare lesion originates from dental lamina and clinically, it may be mistaken for many other odontogenic cysts and tumors. microscopically, it should be distinguished from kcot because of differences in biologic behavior and histologic features.   case: an interesting case of ooc arising in the edentulous mandibular right first premola...

Calcifying epithelial odontogenic tumor is a rare lesion. We report the imaging features of a calcifying epithelial odontogenic tumor. The imaging including conventional radiograph, CT and MR imaging revealed a well-defined lesion in the alveolar bone of the left maxilla, which contained an impacted tooth and some small radiopacities. CT and MR imaging demonstrated a contrast enhancement mainly...

Calcifying epithelial odontogenic tumour (Pindborg tumour) is a rare benign neoplasm with a poorly understood histogenesis. This report describes a single case of a maxillary calcifying epithelial odontogenic tumour including immunohistochemical analysis. The vast majority of tumour cells were positive for CK5/6 and p63. Furthermore, basal cells also displayed moderate reaction for vimentin and...
