A 13-year old boy was referred to the dept. of Oral Surgery in Dental Infirmary of S.N.U. and followed by thorough examination, was diagnosed as an odontogenic cyst in maxilla. The author has reported this case because it is a rare one that the expansion of two different preoccurred odontogenic cysts formed a large fused-type cystic cavity and complete enucleation of the mass under general anesthesia brought satisfactory results.

함치성 낭종은 미맹출치의 치관을 둘러싸는 퇴축법랑상피로부터 기원한다. 대부분의 함치성 낭은 적출술 또는 조대술로 치료된다. 조대술을 통해 낭 내부의 압력이 감소하고 골의 재생이 일어나면서 낭벽은 정상적인 점막으로 변하게 된다. 조대술은 적출술에 비해 인접 주요 구조물을 보호할 수 있다는 장점이 있다. 본 증례는 5세와 11세 남아의 상악 정중 과잉치와 치수 치료된 하악 유구치 부위에서 발견된 각각의 함치성 낭종을 치료한 증례로 모두 낭의 크기가 2개 이상의 인접 영구치의 변위를 발생시킬 정도로 크기가 매우 컸다. 환자의 나이가 어리고 낭의 크기가 커서 조대술을 이용하여 치료하였고 그 결과 변위된 인접 영구치의 맹출 방향이 개선되고 방사선투과상의 크기가 점점 감소하는 것으로 관찰되었다. 본 증례와 같이 크기가 매우 큰 함치성 낭의 경우에서 조대술을 이용하여 치료할 경우 위치가 변이된 인접치아를 보존하고 영구치의 자연 맹출을 유도할 수 있는 양호한 결과가 예상되기에 보고하는 바이다.

The occurrence of odontogenic epithelium in the well of a dentigerous cyst is a well known entity. This epithelium usually remains inactive and does not have clinical significance. However, these small inactive islands of epithelium may be stimulated, resulting in an ameloblastoma. Therefore correct diagnosis and proper treatment are very important. A 15 year-old boy came to the outpatient clinic on August 13, 1979. The Chief complaint was pain, difficulty in mouth opening and swelling of the right mandible of 1 month's durations. With the X-ray filming, it was revealed that dentigerous cyst had been originated from the third molar, occurred in posterior region of the right mandible involving the 1st and the and molar and the portion just beneath the sigmoid notch area. Pus discharged from the gingival sulcus distal to the 2nd molar and it was sure that the cyst had been infected. Enucleation performed with careful excision of all cyst wall was successfully carried out, and recovery and heading were rapid and uncomplicated.

The salivary duct cyst is a rare disease and usually found in the parotid gland. A 55-years-old man presented swelling in the left buccal area and pathological diagnosis was a salivary duct cyst. Though its recurrence has been reported rare, the presented case showed recurrent swelling after enucleation. The recurrent lesion was successfully treated by incision and drain insertion.

Traumatic bone cyst (TBC) occurs preferentially on the mandibular symphysis and body, but rarely on the mandibular condyle. When TBC occurs in the condylar area, it can usually be related with or misdiagnosed as a temporomandibular joint disorder. A 15-year-old female patient visited the Temporomandibular Joint Clinic with a 5-year history of pain and noise localized in the left temporomandibular joint. On imaging, a well demarked oval-shaped radiolucent lesion was observed on the left condyle head. The patient underwent cyst enucleation and repositioning of the bony window on the lateral cortex of the affected condyle head under the impression of subchondral cyst or TBC; however, no cystic membrane was found. The bone defect resolved and showed no recurrence on the serial radiographic postoperative follow-up for 43 months after surgery.

Glandular odontogenic cyst(GOC) is a rare cyst of odontogenic origin, first described in 1988 by Gardner et al. Three glandular odontogenic cysts are presented which were experienced in the Dept. of Oral and Maxillofacial surgery, Yonsei University. The clinical characteristics, radiologic and histopathologic features, and method of treatment are discussed. One occured in the anterior maxilla, others in the mandible body area. One in the anterior maxilla showed swelling and tenderness, others not. All the lesion presented radiographically unilocular radiolucent lesion. Histopathologically, those were lined by nonkeratinizing stratified squamous epithelium of varying thickness showing plaque-like or spherical thickening. Partially, eosinophilic cuboidal cells lined the intraepithelial microcysts. Also, ciliated cuboidal cells and mucinous cells were observed. The cysts were treated by enucleation.

We reviewed 30 cases of keratocystic odontogenic tumor (KCOT) managed during the 8-year period between 2001 and 2008. This case report described the clinical, radiographic and histopathologic features of these KCOT. Of the 30 patients in whom KCOTs were diagnosed, 18 (60%) of the patients were male and 12 (40%) were female. The mean age of these patients was 34.2 years, with peak incidence occurring in the third decade of life. The lesions were mostly located in the mandible (74.2%) and in the maxilla (25.8%). There was a marked predilection to occur in the posterior mandible. Radiographically, 19 (63%) out of the 30 cases were unilocular type with a well demarcated border, while 11 cases (37%) were multilocularin appearance. Histopathologically, 73% of the cysts were lined with parakeratinized stratified squamous epithelium, while only 3% of the cysts were lined with mixed parakeratinized of orthokeratinized epithelium. 22 cases (73%) contained keratin in the lumen. A satellite cyst was observed in 14 cases (47%). All cysts were treated by enucleation. The recurrence rate was shown as 10% for 3 patients with a follow up period and recurred lesions were treated by re-enucleation.

Purpose : This study was designed to evaluate the clinical aspect of cysts which arised in the oral and maxillofacial region. Patients and Methods : We reviewed clinical record, radiograph, histopathologic and operative report of 155 patients who had been diagnosed as cysts and treated at the department of oral and maxillofacial surgery in Chonnam National University Hospital from January 2003 to December 2008. Gender, age, classifiaction, anatomic distribution, clinical sign and symptoms, treatment, complications and recurrence rate were studied. Results : 1. Among 155 patients, the male patients(64.5%) were more than the female(35.5%). 2. The average age ofthe patients was 37.2 years(ranging from 5 to 79 years). 3. In pathologic classification, radicular cyst and dentigerous cyst were most common cysts, irrespective of 73 cases(48.3%) and 35 cases(23.2%). 4. The frequently involved cystic regions were followed as mandibular molars(38.1%), and maxillary incisors(30.2%). 5. The frequent sequence of clinical symptoms was edema(29.9%), no symptom(18.9%), tenderness(13.9%), pain(11.5%) and abscess(9.4%). 6. The most prevalent treatment was the combination operation, such as cyst enucleation with extraction or endodontic treatment of the causative tooth(76.8%) 7. Among 155 cases, 2 cases that were treated using enucleation method were recurred(1.3%).

Odontogenic cysts are relatively common pathologic lesions found in the oral and perioral structures, but the case of squamous cell carcinoma arising from those cysts are very uncommon. After first reported of that case in 1889 by Herman, Schwimmer collected 56 cases of previously reported squamous cell carcinoma arising in residual odontogenic cyst during about past one century. More than 60% of cases of carcinoma developing in odontogenic cysts arising in inflammatory periapical or residual cyst, and these tumors are usually well-differentiated with relatively good prognosis, and often are diagnosed as benign lesion in radiographic or clinical examination, therefore definitive diagnosis must be made by histologic examintation. We report a case and review the literatures, in our case, 78-year old woman were clinically and radiographically diagnosed as residual odontogenic cyst. But in histologic examination after enucleation of lesion, mass of squamous cell carinoma were observed, but in other area, typical cyst wall and lining epithelium were observed. And in some area, carcinoma in situ and invading squamous cell carcinoma into the lining epithelium were also observed.
