OKC of the maxillary sinus mimicking dentigerous cyst
The present article, published in the International Journal of Clinical Pediatric Dentistry, reports a case of follicular OKC in an 8-year-old boy which was concluded as a dentigerous cyst by radiographic features.

An 8-year-old male patient reported to a dental clinic with the chief complaint of swelling in the upper right front tooth region since 1 year. Extraoral examination showed slight swelling was present on the right side of face, causing elevation of right ala of nose.

A large radiolucent lesion of 2 × 2 cm in size was found in the right side of face area in relation to periapical region of 54 and 55. Tooth bud of 14 was being pushed close to the region of floor of the orbit and tooth bud of 15 being pushed posteriorly.
The borders of the lesion are ill defined.

Coronal computed tomography showed a radiolucent lesion in relation to right maxillary sinus area with tooth bud being displaced close to the region below the floor of the orbit. Considering the clinical and radiologic presentations, a provisional diagnosis of dentigerous cyst was determined.

The patient underwent surgery under general anesthesia. A mucoperiosteal flap was opened; the entire cyst lining was enucleated along with the fibrous capsule and was sent for histopathological examination.

Histopathological examination revealed odontogenic epithelial lining of 6 to 9 cell thickness, which exhibited a wavy appearance. The basal epithelial layer was composed of palisaded columnar cells. There was also presence of small satellite cystic islands of odontogenic epithelium seen in the fibrous connective tissue. Histopathological features were suggestive of KCOT.
