Résumé
Calcifying odontogenic cyst [COC] is an uncommon developmental odontogenic cyst first described by Gorlin in 1962.It is named cystic calcifying odontogenic tumor in new classification by WHO. It is considered as extremely rare and accounts for only 1% of jaw cysts reported. It is unusually seen associated with odontoma. The Case was a 15 year-old male patient with the chief complaint of painless swelling in the right side of anterior part of his maxilla. Radiographic pattern was radiolucent with radioopacitis foci. In histopathological view, epithelium of odontogenic cyst with ghost cells and complex odontoma were seen. Treatment was done by enucleation, in 6 months follow up there was not any recurrence. Clinical and radiographic features of odontogenic lesions were non-specific. Always we must careful that the type of lesion associated to Gorlin cyst appoints the clinical behavior, method of treatment and prognosis of combined lesion
Résumé
The term calcifying odontogenic cyst was first used by Gorlin in 1962 to describe a new cystic entity with a peculiar pathogenesis and histologic feature. Other odontogenic tumors such as ameloblastoma, odontoma, amelobalstic fibroma, ameloblastic fibroodontoma, odontoameloblastoma, pindborg's tumor, and adenomatoid odontogenic tumor may seldom be associated with this lesion. This paper describes the case of a 16-year-old male with a remarkable combination of two entities. The lesion associated with an impacted canine tooth was detected at the mandibular left side, producing an extensive expansion of buccal cortical plate on panoramic view. During the operation, enucleation of the cyst was performed and the impacted canine tooth was extracted. The histologic specimen revealed the diagnosis of an adenomatoid odontogenic tumor [AOT] in a calcifying odontogenic cyst [COC]
