치성종양은 악구강계 영역의 질환 중 중요한 관심거리가 되어왔으며, 이중 상피성 치성종양에 관한 보고는 많으나, 중배엽성 치성종양에 관한 보고는 많이 이루어지지 않았다. 저자는 1975년부터 1985년까지 서울대학교병원 치과진료부에서 방사선학적, 병리학적으로 중배엽성 치성종양인 치성섬유종, 치성점액종, 백악질형성섬유종으로 진단된 증례들을 토대로 하여 연구, 분석한 결과 다음과 같은 결과를 얻었다. 1. 치성섬유종의 연령분포는 32세에서 72세로 광범위 하였으며, 발생위치는 모두 상악구치부이었고, 단방성이 2증례, 다방성이 1증례이었다. 2. 치성점액종의 연령분포는 40세에서 55세로 비교적 중년층에서 호발했고, 4증례가 상악에, 2증례가 하악에 발생하였다. 6증례 모두 방사선학적으로 다방성 방사선투과성을 보였으며, 경계는 비교적 불분명하였다. 3. 백악질형성섬유종은 주로 ?년에서 중년 성인 사이에 많이 발행하였고 40대에 가장 많은 출현율을 보였다. 남녀비는 약 1:2로 여자에게서 빈발하였다. 19증례중 하악에 15증례, 상악에 4증례가 발생하여, 하악이 호발부위였으며, 상하악 소구치, 대구치 부위에 발생하였다. 방사선학적으로 방사선투과성이 2증례, 혼합성이 12증례, 방사선불투과성이 5증례이었다.

The neoplastic variant of calcifying odontogenic cyst has various designation, and its malignant counterpart has been reported as aggressive epithelial ghost cell tumor or odontogenic ghost cell carcinoma. Odontogenic ghost cell carcinoma(OGCC) is a rare carcinoma first documented in 1985. It is composed of varying sized islands of anucleated cells with homogenous, pale eosinophilic cytoplasm, so called ghost cells, were admixed with nucleated cells. We report a case of maxillary OGCC developed from odontogenic epithelial tumor in a 25-year-old man with literature review.

The keratocystic odontogenic tumor (KCOT) is a unique cyst because of its locally aggressive behavior, high recurrence rate and characteristic histological appearance. Various options are available for treatment. While some clinicians advocate aggressive forms of dental treatment, others prefer more conservative therapy. In this study, two types of conservative surgical procedures were performed to treat the tumor; marsupialization and cyst enucleation. The patients showed healing process on conservative surgical treatment and teeth erupted without recurrence. Conservative surgical treatment can be an effective treatment option for young children because of their efforts to preserve teeth and other anatomical structures.

Nevoid basal cell carcinoma syndrome(NBCCS) is a autosomal dominant disorder, and its major manifestations are multiple basal cell carcinoma, keratocystic odontogenic tumor, rib anomalies, palmer and plantar pits, calcification of the falx cerebri. Keratocystic odontogenic tumor(KCOT) is defined as intraosseous tumor of odontogenic origin with a characteristic lining of parakeratinized stratified squamous epithelium and potential aggressive behavior. We report a case of a 3-year-old patient with nevoid basal cell carcinoma syndrome who initially presented with unilocular keratocystic odontogenic tumor in maxillary canine region. Keratocystic odontogenic tumor was treated by enucleation, and periodic follow-up check will be required for early diagnosis of additional diseases related with this syndrome.

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.

Occurrence of multiple cysts in jaw bone is rare compared to solitary cysts. numerous cysts occurring in jaw bone which not accompany any syndromes are defined as multiple jaw cysts, and most of these cases in children are keratocystic odontogenic tumor (KCOT) Multiple KCOT occurring in children are often associated with basal cell nevus syndrome(BCNS), so if multiple cysts are found on the radiograph, we suspect this syndrome and pursue clinical and pathological tests. In this case, a pediatric patient, reporting with multiple cysts in the jaw was suspected of BCNS, but hasn't shown any other symptoms of this syndrome up to date, and has kept repeating surgical operation and recurrence of the tumor. Although no symptoms besides multiple jaw cysts is present, it is often reported that other symptoms appear late in the patient's age. Therefore, in cases where multiple odontogenic tumors are found in children, continuous radiographic and clinical follow-ups in order to check the progress of the syndrome is considered important.

The basal cell nevus syndrome is also known as the Gorlin-Goltz syndrom. It is a dominant autosomal disorder which is characterized by keratocystic odontogenic tumors in the jaw, skeletal abnormalities, and multiple basal cell nevi carcinomas. This study reports an 11-year-old boy with multiple odontogenic keratocysts in the jaw, hypertelorism, and frontal bossing. When a young patient has cystic lesions with an impacted permanent teeth, it is important to preserve the teeth. For a growing patient with impacted permanent teeth, a more conservative method is suggested, which will enable the preservation the permanent teeth in Gorlin-Goltz syndrome.

Adenomatoid odontogenic tumor (AOT) is a rare benign odontogenic jaw lesion. It usually occurs in the anterior maxilla and is mostly related to impacted canines in teenagers. A 3-year-old girl was referred from a local dental clinic due to delayed eruption of the right primary mandibular 2nd molar. There was no history of pain or swelling. Radiography revealed a large radiolucency lesion with radiopacities around the unerupted right primary mandibular 2nd molar. Surgical enucleation with extraction of the right primary mandibular 2nd molar and surgical biopsy were performed. Based on the clinical and radiological findings, this lesion was defined as an ameloblastic fibro-odontoma which often develops in the mandible of adolescents. However, this lesion was diagnosed as AOT from the results of the histological examination. This report aimed to present a rare case of AOT in the posterior mandibular area in a very young patient.

낭은 상피세포로 싸여있는 병적인 공간으로 내부가 액체나 반액체로 채워져 있다. 악골에서 낭은 다른 골 부위에서보다 더 흔하게 발생하는데 이는 대부분의 낭이 치아 형성 후에 악골에 남아있는 치성잔류물로부터 발생하는 경우가 많기 때문이다. 구강악안면부에서 발생하는 낭은 연조직에서 발생할 수도 있지만 대부분 골내에서 발생하고, 법랑질 상피나 치배와 관련해 악골내에 발생하는 치낭성이다. 치낭성은 WHO분류에서 발생근원에 따라 크게 염증성과 발육성 기원의 두 가지 군으로 분류되고, 발육성 낭은 치성과 비치성으로 세분할 수 있다. 악골에 발생하는 낭은 대부분이 치낭성이며 가장 흔한 악골 낭종은 치근단낭으로 염증성이고, 발육성인 함치성낭과 치성각화낭도 다음으로 발생률이 높은 편이다. 소아환자에서 함치성낭과 치성각화낭의 발병률이 성인보다 더 높았다. 비치성낭 중에서 비구개관낭이 가장 많이 발생하며, 연조직에서 발생하는 낭과 상피세포 경계가 없는 낭성 병소인 가성낭(pseudocyst)은 드물게 관찰된다. WHO에서 치성각화낭과 서회화치성낭은 파괴적 성장을 하고 재발 경향이 높으므로 양성 낭성 종양으로 재분류하고 있다.

The calcifying epithelial odontogenic tumor is a rare benign odontogenic neoplasm which was first described by Pindborg in 1955 and accounts for less than 1％ of all odontogenic tumors. The tumor occurs primarily in the molar-premolar region of the mandible, and 52％ of cases are associated with an unerupted tooth. The clinical feature is most commonly a slow-growing painless swelling. The tumor may show considerable radiographic variation and usually characteristic histopathologic features. In this study, we report a case of the calcifying epithelial odontogenic tumor on the left mandibular body and ramus area in a 28-year-old male with a brief review of the concerned literatures.
