Abstract

Adenomatoid odontogenic tumor(AOT) is an infrequent odontogenic tumor which arise in the jaw. It was considered as a variant of ameloblastoma. The adenomatoid odontogenic tumor is clearly benign and, in contrast to the ameloblastoma, present a very low recurrence. It most often appears in the canine region of the maxilla. The adenomatoid odontogenic tumor is frequently asymptomatic, however it may cause painless swelling. The radiological findings of adenomatoid odontogenic tumor frequently share characteristics of dentigerous cyst and unicystic ameloblastoma. Conservative surgical enucleation and curettage are the treatment of choice. In this case a 10-year-old child was presented with mandibular right lateral incisor in unerupted. Radiographically, the tooth was impacted and a radiolucency was seen in the area. The lesion was enuclated without extraction of the tooth. Bracket was attached on the tooth for orthodontic extrusion installed. Histopathologically adenomatoid odontogenic tumor was revealed.

선양 치성 종양(adenomatoid odontogenic tumor)은 악골에 드물게 발생하는 치성 기원의 종양이다. 이전에는 법랑모세포종(ameloblastoma)의 한 종류로 여겨졌으나 양성이며 재발되는 경우는 극히 드물다. 상악 견치에 호발하며 대개는 무증상이지만 크기가 천천히 커져 무통성 종창을 일으킬 수 있다. 방사선학적으로 함치성 낭종(dentigerous cyst) 및 단방성 법랑모세포종(unicystic ameloblastoma)과 매우 유사하다. 일반적으로 보존적인 소파술(curettage) 및 적출술(enucleation)을 통해 치료한다. 본 증례는 하악 우측 측절치 미맹출을 주소로 내원한 10세 여자 환아에서 방사선 사진 검사를 통해 치아의 매복 및 병소를 확인하고 적출술을 시행하였다. 치아에는 브라켓을 부착하여 교정적 정출을 유도하였다. 조직학적 검사를 통해 선양 치성 종양으로 확진되었으며 양호한 치료 결과를 보였기에 보고하는 바이다.
