- This is a case report of a benign osteoblastoma in the temporomandibular joint of a 17-year-old female. The patient had a two-and-a-half-year history of reduced mouth opening accompanied by tenderness and swelling in the left temporomandibular joint (TMJ). Initial treatment included stabilization of occlusion with a splint, jaw exercise and analgesics. At first symptoms decreased, but then increased 18 months later, prompting evaluation by a cone beam computed tomography (CBCT) scan of the joint. The radiographic findings showed a somewhat ill-defined, radiolucent, expansile lesion containing small scattered calcifications. The lesion was removed under general anesthesia and sent for histopathological examination. At 12-month follow-up the patient had normal function in the TMJ without clinical symptoms. CBCT examination showed a small recurrence of 3 millimeter. Another 12 months later CBCT showed a 1 mm increase of the recurrence. Function was normal with a subtle tenderness lateral to the left TMJ. The decision from a multidisciplinary meeting was further annually follow-up. The present case illustrates the importance of radiographic examination of patients with temporomandibular dysfunction when conservative treatment of symptoms does not relieve pain or swelling.

- CEOT is a rare benign, but locally aggressive odontogenic tumor, and some authors have claimed that the biologic behavior of the clear cell variant is even more aggressive, with greater propensity to recur. We report a rare case of clear cell calcifying epithelial odontogenic tumor (CEOT) and discuss its possibly aggressive behavior. A 40-year-old woman experienced an asymptomatic expansion of the left posterior mandible. After radiographic examination and biopsy, a block resection was performed. Histologic examination included analysis of Ki-67 reactivity as a marker of tumor growth activity. Ki-67 labeling was pronounced in the non-clear cell population in the tumor periphery but low in the central and clear cell portions. Clinical and radiographic follow-up 6 years after resection has not revealed any signs of recurrence. On the basis of a review of the literature and our own findings, there is no clear data to suggest that clear cell CEOT exhibits more aggressive behavior compared with conventional CEOT.
