Basal cell nevus syndrome is inherited as an autosomal dominant trait with variable expressivity. This syndrome comprises a number of abnormalities such as multiple nevoid basal cell carcinomas of the skin, skeletal abnormalities as bifid rib and fusion of vertebrae, central nervous system abnormalities as mental retardation, eye abnormalities, and multiple odontogenic kerato cysts. In 1960, Gorlin and Goltz first described the features of this disease as constituting a true syndrome; since then, it has been realized that it is much more complex and encompassing than initially thought. This patient has many symtoms of basal cell nevus syndrome. - we has known multiple jaw cysts through panorama and facial computed tomography. He has hyperchromatism on basal cell through skin biopsy. In ophthalmologic consult, he has blindness on right. On his past medical history, amputation was done on his toes for polyductalism. - So we report with literature reviews

Objectives: This study aimed to determine the prevalence of odontogenic cysts, tumors, and other lesions among reports in the archives of the Department of Oral and Maxillofacial Surgery at the Faculty of Dentistry affiliated with Kocaeli University collected over a four-year period. Materials and Methods: In this retrospective study, patient records from the archive of the Department of Oral and Maxillofacial Surgery from 2014 to 2018 were reviewed. Patient demographic information (age and sex) and lesion location were recorded and analyzed. Results: From a total of 475 files reviewed, odontogenic cyst was confirmed in 340 cases (71.6%), and odontogenic tumor was confirmed in 52 cases (10.9%). Regarding odontogenic cyst type, the most common was radicular cyst (216 cases), followed by dentigerous cyst (77 cases) and odontogenic keratocyst (23 cases). Among odontogenic tumors, the most frequent was odontoma (19 cases), followed by ossifying fibroma (18 cases) and ameloblastoma (9 cases). Giant cell granuloma was also reported in 35 cases. Conclusion: The distribution pattern of odontogenic cysts and tumors in our retrospective study is relatively similar to that reported in the literature. Complete clinical reports for final diagnosis of these lesions and routine follow-up examinations are very important for treatment.

The WHO separates odontogenic carcinomas into three groups : malignant ameloblastoma, primary intraosseous carcinoma(PIOC), and carcinomas arising from odontogenic epithelium including those arising from odontogenic cysts. In WHO criteria, primary intraosseous carcinoma is defined as a squamous cell carcinoma arising within the jaw, having no connection with the oral mucosa, and no developing from residues of odontogenic epithelium. This is a case of 52-year old man who had prolonged jaw pain and final diagnosis was primary intraosseous carcinoma(PIOC) on mandible. We obtained successful result after composite resection combined with hemimandibulectomy, RND, following reconstruction with latissmus dorsi myocutaneous flap, and postoperative radiation therapy.

함치성 낭종은 일반적으로 미맹출 치아의 치관을 포함하고 있는 형태로, 치아 법랑질과 이장 상피 사이에 액체가 축적되어 생긴 잔존 법랑 상피조직의 퇴행성 변화로 부터 생긴다. 치근단 낭 다음으로 가장 흔한 치성 낭종으로, 주로 단독으로 발생하고 하악 제 3대구치와 상악 소구치에 호발한다. 악골의 다발성 낭종은 주로 기저세포 모반 증후군과 관련된 치성 각화낭이 대부분이고, 점액다당류증 또는 쇄골두개 이형성증과도 관련이 있을 수 있다. 단발성의 함치성 낭종은 우리에게 친숙할 정도로 유병율에서 치료 및 예후까지 잘 알려져 있으나, 전신병력이 없는 다발성의 함치성 낭종은 드물며, 상악과 하악에 발생한 다발성 낭종은 특히 더 드물다. 본 증례는 편측성으로 양악에 함께 발생한 다발성의 함치성 낭종을 가진 11세 소년에 대한 치료 증례로 1년간의 관찰 후 양호할만한 결과를 얻었기에 보고하는 바이다. 1년이라는 관찰 기간이 짧기 때문에 향후 지속적인 임상적, 방사선적 관찰을 필요로 하리라 사료된다.

악골의 낭종은 크게 치성과 비치성으로 구분되며 치성낭은 치성기관이나 그 잔존 세포성분과 관련되어 주로 골내에서 발생한다. 비치성낭종은 과거에는 태아의 발육중 상피의 봉입이나 융합선을 따라 존재하는 상피잔사가 증식하여 낭성변형을 일으킨다는 설이 유력하였으나 현재에는 이러한 태아의 발육 동안상피의 봉입은 일어나지 않는 것으로 보고 있다. 함치성낭은 미맹출 치아와 관련되어 발생하고 상피의 전암 가능성이 있으므로 가능한 발리 제거하도록 하며 조대술이나 적출술이 이용될 수 있고 간혹 원인치의 발거가 추천된다. 비구개낭은 가장 일반적인 비치성낭으로 상악 중절치 사이에 경계가 명확한 방사선 투과상으로 나타난다. 적출술과 조대술로 치료할 수 있으며 전암 가능성이나 재발은 드물다. 본 증례에서는 전북대학교 병원 소아치과에 내원한 아동의 악골내 발생한 낭종을 외과적으로 제거한 후 다음과 같은 결론을 얻었다. 1. 함치성낭의 환아에서, 원인 치아를 보존하고 완전 적출술로 병소를 제거한 후 경과를 관찰한 바 영구치의 정상적인 맹출이 이루어졌다. 2. 비구개낭을 치료시, 인접치아의 생활력에 대한 정확한 진단과 그에 따른 치료법의 선택으로 불필요한 근관치료를 피할 수 있다. 3. 향후 비구개낭의 환아의 관련치에 대한 계속적인 관찰이 필요하리라 사료된다. 4. 악골내 방사선 투과성의 병소를 치료시, 정확한 감별진단과 적절한 치료법의 선택이 중요하다.

Purpose: This study was designed for identification of the main clinicopathological features of cysts in the oral and maxillofacial regions. Methods: A retrospective observational study was conducted on 164 patients who had been diagnosed with cyst of the jaw, from the database of 168 histopathological diagnoses at the Department of Oral and Maxillofacial Surgery of Busan Paik Hospital at Inje University, from January 2009 to December 2011. The subjects were treated and the following variables were recorded: gender, age, clinical signs and symptoms, histopathological distribution, treatment methods, and complications. A descriptive analysis of the study variables was performed using a chi-square test. Results: Among the 164 patients, there were more male than female patients (male-female ratio: 1.7:1). The most predominant ages were the 20s and 40s. Among the classes of pathological cysts, radicular cysts and dentigerous cysts were the most common, with incidences of 56.0% and 35.1%. Thirty-six percent of the patients had no symptoms; and of those who had symptoms, the main signs and symptoms were swelling (24.4%) and pain (17.1%). The most frequent management method was the combination operation, such as enucleation with or without extraction and apicoectomy of the causative teeth. Of the 164 patients, 13 had complications; and one patient who had been treated with enucleation with apicoectomy had a recurrent cyst. Conclusion: Using a chi-square test, no significant differences in prevalence were observed in relation to gender according to age. Comparative analysis of radicular and dentigerous cysts showed a significant difference in their prevalence according to their anatomical location, however, no significant differences in were observed in their incidence rates according to age.

The authors had observed clinically and histopathologically on the 5 cases of globulomaxillary cysts. The results are as follows: 1. All cases occurred in men, and the average age was 33.6 year,; the oldest was 38 year and the youngest was 31 year old. 2. Four cases occurred in upper left jaw and the one was in right. 3. By the roentgenogram, well demarkated line between the cyst and intact bone were observed as pea shaped radiolucency between the canine and the lateral incisor. In most cases alveolar bone was involved from the central incisor to the premolar region. 4. Thick stratified squamous epithelium was covering the connective tissue wall. There were no keratinization except one case of parakeratosis which had massive inflammatory infiltration. Inflammatory infiltration was obsereved in most cases.

Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, is characterized by various embryological deformities and carcinoma formation. It is caused by PTCHI gene mutations and is autosomal dominantly inherited. Some of the main symptoms of NBCCS are multiple basal cell carcinomas, multiple keratocystic odontogenic tumors (KCOTs) of the mandible, hyperkeratosis of the palmar and plantar, skeletal deformity, calcification of the falx cerebri, and facial defomity. Recurrent KCOT is the main symptom of NBCCS and is present in approximately 90% of patients. In NBCCS, KCOTs typically occur in multiples. KCOTs can be detected in patients under the age of 10, and new and recurring cysts develop until approximately the age of 30. The postoperation recurrence rate is approximately 60%. This case report presents a 14-year-old female patient with a chief complaint of a cyst found in the maxilla and mandible. The patient was diagnosed with NBCCS, and following treatment of marsupialization and enucleation, the clinical results were satisfactory.

Background: For normalization of displaced anatomical structure by large cyst, two-step procedure (decompression and enucleation afterward) has been recommended. However, the histological transformation after cystotomy for decompression was shown frequently in secondary enucleation. Therefore, analyses about effects and histological changes after decompression have been necessary. Methods: 48 cases diagnosed as large odontogenic cyst in the jaw and treated by decompression and secondary enucleation were retrospectively analyzed in clinical, rediographical, and histological aspects. Results: In dentigerous cyst, decompression was much useful. Impacted permanent teeth were erupted and reduction rate was higher than that of odontogenic keratocyst (OKC) and apical periodontal cyst. In OKC, among the 29 cases, 11 cases showed no-keratosis, proliferation and rete-ridge elongation after decompression. 4 cases showed no-keratosis, only. 7 cases showed orthokeratosis and rete-ridge elongation and 6 cases showed reteridge elongation, only. 1 case had no change. And the recurrence rate for OKCs was 10.3%. For all odontogenic cysts in this study, dysplasia was not found in cystic lining after decompression. Conclusions: This study implied that decompression for large odontogenic cyst was useful treatment modality because it was conservative treatment and recurrence rate was low although long treatment period was required.
