Ameloblastic fibro-odontoma is a rare benign mixed odontogenic tumor with histologic characteristics of ameloblastic fibroma and complex odontoma. As with ameloblastic fibroma, it may be asymptomatic or found because of painless swelling and delayed eruption of associated tooth. This report presents a case of ameloblastic fibro-odontoma in the posterior mandible of a 14-year-old girl and analyses its clinical features and radiographic features on plain X-ray film and CT images.

Ameloblastic fibro-odontoma(AFO) is a rare mixed odontogenic tumor. It is composed of connective tissue characteristic of an ameloblastic fibroma and calcified tissue as a complex or compound odontoma. AFO usually presents itself as an asymptomatic swelling of jaw or failure of tooth eruption. The lesion usually occurs in individual less than 30 years old. The differential diagnosis of this tumor includes odontoma, ameloblastoma, and ameloblastic fibroma. This report describes an ameloblastic fibro-odontoma occurring in maxilla of sixteen-year-old female. The lesion was treated by surgical enucleation and curettage without extraction of the involved canine(#23). This patient has shown no sign of recurrence during postoperative 34 months. So we report our case with review of literatures

법랑모세포 섬유치아종(Ameloblastic fibro-odontoma)은 하악 구치부에 호발하는 드문 혼합 치성종양이다. 방사선적 소견으로는 경계가 명확하고, 대부분에서 방사선 투과상과 불규칙적인 크기와 형태의 불투과상이 혼재된 양상으로 관찰된다. 조직학적으로 법랑모세포 섬유치아종은 법랑모세포 섬유종의 연조직 성분과 복합성 치아종의 경조직 성분을 모두 가지고 있다. 본 증례의 13세 2개월된 남자 환아는 원광대학교 치과대학 치과병원 소아치과에 하악 좌측 견치의 맹출 지연을 주소로 내원하였다. 맹출을 방해하는 병소를 적출하고 조직 생검한 결과, 법랑모세포섬유치아종으로 진단하였다. 지속적인 예후관찰 중 병소 제거 수개월 후 견치는 정상적으로 맹출하였다.

Ameloblastic fibro-odontoma is an extremely rare odontogenic tumor composed of proliferating ectodermal and mesenchymal components of odontogenic tissue, containing hard tooth structure. It occurs predominantly in children and young adults. The mandibular molar-ramus area is the most frequently observed location, presenting radiographically as a well-circumscribed and radiolucent-radiopaque tumor. A case involving a 24-year-old woman presenting with a large ameloblastic fibro-odontoma of the posterior mandible is reported. This case is of radiologic interest because two distinct calcification patterns were observed.

Ameloblastic fibro-odontoma (AFO) is a rare odontogenic tumor, which occurs in young children before the age of 20 years. Radiologically, it is a well-defined radiolucent lesion containing radiopaque masses. Histopathologically, AFO is composed of odontogenic epithelium in a primitive-appearing connective tissue and hard tissue consisting of enamel and dentin. It is commonly found in the mandibular posterior region. AFO may be asymptomatic and is often associated with delayed tooth eruption. As it shows similar characteristics clinically and radiologically to odontoma, differential diagnosis through histopathological examination is important. Treatment of AFO is conservative enucleation, and teeth enclosed or associated with the lesion may require extraction. In this report, 2 young patients who visited our clinic with a chief complaint of delayed eruption were diagnosed as AFO with radiological and histopathological examination. After the surgery, the healing status was found to be favorable, and no evidence of recurrence was observed.

Thirteen-year-old girl complaining of the swelling and pain on the left midface visited our dental hospital. On the radiographic examination, well-defined radiolucent lesion with hyperostotic border was found in the left maxilla accompanying with the external root resorption of the involved teeth and the displaced second molar. CT showed calcified bodies, thinning of hard palate, inferior orbital wall and lateral wall of nasal fossa, and thinning and perforation of the buccal plate of the maxilla. Enucleation and curettage of the lesion and nasoantrostomy was carried out and histopathologic examination mainly showed a solid tumor tissue composed of odontogenic epithelium and pulp tissues admixed with dentin and enamel formation. And some part of reduced follicular epithelium of tooth germ showed a change mimicking calcifying odontogenic cyst. Taken together, we concluded the lesion is an ameloblastic fibro-odontoma with a change of calcifying odontogenic cyst.

Ameloblastic fibrodentinoma (AFD) is a rare benign odontogenic tumor that resembles an ameloblastic fibroma with dysplastic dentin. This report presents a rare case of mandibular AFD with imaging features in a young patient. Panoramic radiography and computed tomography revealed a well-defined lesion with internal septa and calcified foci, causing inferior displacement of the adjacent molars as well as buccolingual cortical thinning and expansion of the posterior mandible. The lesion was surgically removed via mass excision, and the involved tooth was extracted under general anesthesia. During the 5-year follow-up period, no evidence of recurrence was observed. Radiologic features of AFD typically reveal a moderately to well-defined mixed lesion with varying degrees of radiopacity, reflecting the extent of dentin formation. Radiologists should consider AFD in the differential diagnosis when encountering a multilocular lesion with little dense radiopacity, particularly if it is associated with delayed eruption, impaction, or absence of involved teeth, on radiographic images of young patients.

선양 치성 종양(adenomatoid odontogenic tumor)은 소아에서 드물게 발생하는 악골의 치성 기원의 종양이다. 보통 10대에서 상악 견치부분에 발생한다. 이 증례는 3세 여환으로 하악 제2유구치의 미맹출을 주소로 개인병원에서 의뢰되었다. 부종과 통증의 병력은 없었다. 파노라마 사진에서 매복된 하악 제2유구치의 주변으로 방사선투과상 병소가 관찰되었고, Cone Beam Computed Tomography (CBCT) 에서는 골팽창과 함께 방사선 불투과상 병소들이 관찰되었다. 하악 제2유구치의 발치와 함께 병소의 적출과 조직 생검이 시행되었다. 술 후 1년 검사에서 재발을 보이지 않았다. 임상적, 방사선학적 검사를 통해 이 병소는 소아 청소년의 하악 구치부에서 호발하는 법랑모세포 섬유치아종(Ameloblastic fibroodontoma)로 진단되었다. 하지만 생검의 결과를 통해 이 병소는 선양 치성 종양으로 확진 되었다. 이 증례 보고는 매우 어린 나이에 하악 유구치에 발생한 흔하지 않은 선양 치성 종양 증례를 기술하고 있다.
