Cone Beam Computed Tomography Findings in Calcifying Cystic Odontogenic Tumor Associated with Odontome: A Case Report.

Phulambrikar T, Vilas Kant S, Kode M, Magar S - J Dent (Shiraz) (2015)

Bottom Line: The calcifying cystic odontogenic tumor (CCOT) is a rare cystic odontogenic neoplasm frequently found in association with odontome.Conventional radiographs showed internal calcification within the lesion but were unable to visualize its relation with the adjacent structures and its accurate extent.In this case cone beam computed tomography (CBCT) could accurately reveal the extent and the internal structure of the lesion which aided the presumptive diagnosis of the lesion as CCOT.

ABSTRACT
The calcifying cystic odontogenic tumor (CCOT) is a rare cystic odontogenic neoplasm frequently found in association with odontome. This report documents a case of CCOT associated with an odontome arising in the anterior maxilla in a 28-year-old man. Conventional radiographs showed internal calcification within the lesion but were unable to visualize its relation with the adjacent structures and its accurate extent. In this case cone beam computed tomography (CBCT) could accurately reveal the extent and the internal structure of the lesion which aided the presumptive diagnosis of the lesion as CCOT. This advanced imaging technique proved to be extremely useful in the radiographic assessment and management of this neoplasm of the maxilla.

Figure 9: a: Gross specimen  b: Histopathological findings of the cystic wall and fibrous capsule with ameloblastomatous epithelium containing numerous ghost cells.

Mentions: Surgical enucleation under local anesthesia was performed and a thick cystic wall and mineralized material, compatible with an odontoma in anterior part of the cyst in relation with tooth 21, 22, and 23 was removed, leaving an oval bony defect. (Figure 9a) The H&E staining demonstrated cystic lumen lined by epithelium and connective tissue. Multiple ghost cells were observed. Epithelium was non-keratinized stratified squamous showing basal layer of tall columnar cells with palisaded nucleus suggestive of ameloblast-like cells and overlying stellate reticulum-like cells. The connective tissue showed numerous spindle shaped cells with dense collagen stroma along with Liesegang ring (Figure 9b). Odontogenic rests were also seen within the connective tissue. The histopathological features were suggestive of calcifying cystic odontogenic tumor.
