Fibromyxoma of the jaw is a rare benign mesenchymal odontogenic tumor with locally aggressive behavior. In the present report, a 13-year-old female patient presented to our university hospital with delayed eruption of some of her teeth. A panoramic radiograph taken at the initial examination revealed four pericoronal radiolucencies related to the four third molars. Thereafter, a magnetic resonance imaging (MRI) examination was performed. After the surgical removal of these molars, the microscopic examination diagnosed the four lesions as fibromyxomas. Here, we have discussed the clinical, panoramic radiography, MRI, and histopathological findings of the case.

Familial gigantiform cementoma is a rare fibre-cemento-osseous disease of the jaws which appears to be transmitted as an autosomal dominant trait with variable expressivity of the phenotype. A 7-year-old girl visited DKUDH complaining of the painless facial deformity. Clinically, significant facio-lingual expansion was observed at the left maxilla, left mandibular body and symphysis portion. Malposition of lower anterior teeth was found. Panoramic radiograph and CT scan showed the extensive expansile mixed lesion at maxilla and mandible. Bone scan revealed hot spot at the maxilla and left side of mandible. Histologic examination revealed moderately dense fibrous connective tissue with scattered masses resembling cementum. The patient's mother had a history of the mandibular resection due to benign tumor. Her younger brother had buccal expansion of right mandible. We report our finding of a family that has exhibited clinical, radiographic and histologic findings consistent with the familial gigantiform cementoma.

Amelobalstic fibroma is a rare true mixed tumor of odontogenic origin with both mesenchymal and ectodermal components. It usually appears in the mandible and in the posterior segments of young patients without gender predilection, and sometimes is associated with an impacted tooth. It is a benign slow growing tumor that is less infiltrative than an ameloblastoma but tends to expand bone. Surgical treatment with excision followed by curettage seems to be the most appropriate therapeutic option. The objective of this presentation is to report a case of ameloblastic fibroma of the mandible body in a 14-year-old woman, to make a brief review of the literature about its differential diagnosis and its clinical and histologic features and the treatment.

Ameloblastoma is the most common aggressive benign odontogenic tumor of the jaws. Because of slow growth and tendency to local invasion of bone and soft tissue, high rates of recurrence are common. The treatment for ameloblastoma is still controversial and poses some special problems in children. Because of growth of the jaw and the different incidence, prognosis of the tumor make the surgical consideration different from adults. Radical resection cause facial deformity, jaw abnormal movement and masticatory disturbance especially to child and adolescents. So conservative treatment as enucleation, curettage is acceptable initial treatment of ameloblastoma in children who can be followed up in a precise, detailed manner. This report describes a case of unilocular plexiform ameloblastoma treated by enucleation and curettage followed by marsupialization.

Ameloblastomaa are odontogenic benign tumors with epithelial origin, which are characterized by slow, aggressive, and invasive growth. Most ameloblastomas occur in the mandible, and their prevalence in the maxilla is low. A 27-year-old male visited our clinic with a chief complaint of the left side nasal airway obstruction. Three-dimensional computed tomography showed left maxillary sinus filled with a mass. Except for the perforated maxillary left edentulous area, no invaded or destructed bone was noted. The tumor was excised via Le Fort I osteotomy. The main mass was then sent for biopsy and it revealed acanthomatous ameloblastoma. The lesion in the left maxillary sinus reached the ethmoidal sinus through the nasal cavity but did not invade the orbit and skull base. The tumor was accessed through a Le Fort I downfracture in consideration of the growth pattern and range of invasion. The operation site healed without aesthetic appearances and functional impairments. However, further long-term clinical observation is necessary in the future for the recurrence of ameloblastoma. Conservative surgical treatment could be the first choice considering fast recovery after surgery and the patient's life quality.

법랑모세포섬유종은 드물게 발생하는 양성치성종양으로 조직학적으로 상피, 간엽조직이 증식하는 신생물이다. 방사선학적으로 경계가 명확한 단방성 혹은 다방성 방사선 투과성 병소로 주로 구치부에서 발견되며 서서히 팽창하여 피질골을 팽윤시키고 대구치나 소구치의 맹출을 지연시킬 수 있다. 치료법으로는 완전절제술(radical resection)과 보존적 적출술(conservative enucleation)이 있으며, 흔하지는 않지만 재발과 악성전환의 가능성이 있으므로 술 후 주기적 관찰이 필요하다. 이번 증례는 하악 우측 제 1대구치 의미 맹출을 주소로 내원한 만10세 여자 어린이와 구강 검진을 주소로 내원한 만5세 여자 어린이에서 방사선 투과성 병소에 의한 구치의 맹출장애가 관찰된 경우로, 병소를 포함한 치아를 외과적으로 제거하고 적출물을 조직검사 의뢰하여 법랑모세포섬유종으로 확진되었으며 그 후 양호한 치유과정을 보였다.

Ameloblastoma is a common odontogenic benign tumor of the jaw bone. However, it might be albe to infiltrate into the adjacent tissue, causing bony destruction and high recurrent rate. The aim of the study is to understand the biologic behavior of recurred ameloblastoma through immunohistochemical study. The PCNA, Ki-67, p53 and cytokeratin 17, cytokeratin 18 antibody staining were used. There was significant difference of positive reaction between non-recurred ameloblastoma and recurred ameloblastoma in PCNA and cytokeratin 17. There were no significant difference of positive reaction between non-recurred ameloblastoma and recurred ameloblastoma in p53, Ki-67 and cytokeratin 18. From the above results, it is suggested that the recurrence of ameloblastoma is related to positive reactions of PCNA and cytokeratin 17 and the progonsis of the recurrence of ameloblastoma is able to be predicted by using PCNA and cytokeratin 17.

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.

사기질모세포 암종은 악골에 발생하는 치원성 악성 종양으로 매우 드물게 보고되고 있다. 양성질환의 임상양상을 보이기도 하지만 악골 및 주변조직을 침범해 궤양 형태를 보일 수 있으므로 보통은 조직검사를 통해서 진단이 내려진다. 이런 이유로 수술 절제가 충분치 못할 수 있어 국소재발이나 원격전이의 위험에 노출되게 되므로, 수술 후의 보조적 치료 또는 재절제가 중요하다고 할 수 있다. 저자들은, 하악에서 발생한 사기질모세포 암종의 환자에서 일차 수술 후 충분한 절제연을 얻지 못해 재발한 부위에 대해 재수술 후 재발 위험부위에 대한 보조적 방사선치료를 시행한 증례를 토대로, 최근의 문헌고찰을 통해 사기질모세포 암종 환자에서의 수술 후 방사선치료의 역할에 대해서 의견을 제시해 보고자 한다.
