Simple bone cyst is a pseudocyst that typically occurs in patients during their second and third decades of life. This benign entity is an empty or fluid-filled cavity that lacks a true epithelial lining. Simple bone cysts are often asymptomatic and are commonly found in mandibular body, predominantly in the posterior region. The treatment of simple bone cysts can be influenced by factors such as the patient's age, the size of the lesion, and the presence or absence of symptoms. In the case of a simple bone cyst in the mandible that is small and symptomless, a watchful waiting approach may be appropriate. However, if the cyst is large and symptomatic, surgical treatment is recommended. This report presents a radiological examination of a simple bone cyst that developed around the root of the mandibular first molar in a 36-year-old female patient. The cyst recurred in adjacent areas despite surgical treatment.

Traumatic bone cyst is known as a symptomless, radiolucent bony les ion incidentally found during routine radiographic examinations. The main characters of traumatic bone cyst are asymptomatic and unicystic radiolucent bony lesion with vital tooth. This case is a confusing case of a traumatic bone cyst with sudden gingival swelling and appearance like a periapical abscess. After surgical exploration and drainage, clinical and radiographic examination showed bony healing with pulpal vitality preserved after 7 months postoperatively.

외상성 골낭(Traumatic Bone Cyst)은 상피이장이 없는 비치성낭으로 감염의 증거가 없으며 많은 액체가 내장되는 특징을 가지는 병소이다. 외상성 골낭은 자각증상이 없는 병소로 10대에서 20대 사이에 호발하며 주로 남자에서 호발한다. 병소는 방사선학적으로 조개껍질 모양의 명확한 경계를 가지며 방사선 투과상을 보인다. 병소는 해면골에 위치하며 간혹 치밀골을 팽창시키거나 비박화시킨다. 병소 주변의 치아는 생활력을 유지하는 특징이 있다. 일반적으로 외상성 골낭은 방사선학적, 임상적인 기준으로 진단을 내리게 된다. 외상성 골낭의 치료법은 일반적으로 외과적인 적출술과 소파술을 시행한다. 본 두 증례 중 첫 번째 증례에서 환아는 개인치과의원에서 치수치료 도중 방사선 사진에서 방사선 투과상이 발견되어 본원으로 의뢰되었으며 파노라마 방사선 사진촬영 결과 좌측 하악골에 명확한 경계를 보이는 방사선 투과상을 보였다. 두 번째 증례에서 환아는 치외치인 상악 우측 제2소구치의 농양을 동반한 종창을 주소로 내원하였다가 초진시 촬영한 파노라마 방사선 사진에서 우측 하악골에 명확한 경계의 방사선 투과상을 보였다. 두 증례 모두 임상적, 방사선학적 검사결과 외상성 골낭으로 진단받았다. 첫 번째 증례에서는 생활력을 상실한 인접치아의 치근단공에 과기구 조작을 시행하여 병소를 교통시킨 후 지속적인 세척을 시도하여 병소가 치유되는 양상을 보였고, 두 번째 증례에서는 아무런 처치 없이 지속적인 관찰결과 병소의 크기가 감소하는 양상을 보였다. 본 두 증례에서 외과적인 적출술과 소파술을 시행하지 않고 보존적인 처치를 하였음에도 병소가 치유양상을 보이기에 보고하는 바이다.

Aneurysmal bone cyst is a benign lesion of bone consisting of a septated, cystic cavity filled with non-endothelium-lined, blood-filled spaces. As it grows, expanding and destroying the affected part of the bone by direct compression, the lesion characteristically produces a prominent bulging of the affected bone, which eventually erodes the overlying cortex. Patients rarely complain of pain unless the cyst affects adjacent nerves or its expasion is great enough to impinge on the surrounding joints and soft tissue. Teeth adjacent to the cyst may be displaced, but usually remain vital. Development of the lesion in the craniofacial region is rare, and the mandible is more often affected than the maxilla. Complete surgical excision is used to treat aneurysmal bone cyst, with either curettage or composite resection. This is a case report of 49 years old female with aneurysmal bone cyst treated with surgical excision & DFDB graft.

The aim of this study was to evaluate the clinical, radiographic and histopathologic features of 23 cases of solitary bone cyst by means of the analysis of radiographs and biopsy specimens in 23 persons visited the Department of Oral and Maxillofacial Radiology, School of Dentistry, Kyung Hee University and Chunbuk National University. The obtained results were as follows; 1. The incidence of solitary bone cyst was almost equal in males(52.2%) and in females(47.8%) and the prevalent age of the solitary bone cyst were the second decade(47.8%) and the third decade (21.7%). 2. In the signs and symptoms of solitary bone cyst, pain or tenderness revealed in 17.4%, swelling revealed in 13.0%, pain and swelling revealed in 21.7%, paresthesia revealed in 4.4% and 43.5% were asymptom and the tooth vitality involved in the solitary bone cyst, 76.5% were positive and 23.5% were either positive or negative. 3. In the location of the solitary bone cyst, 47.8% present posterior region, 21.7% present anterior region, 21.6% present anterior and posterior region, 4.4% present condylar process area. 4. In the hyperostotic border of the solitary bone cyst, 47.8% were seen entirely, 21.8% were seen partialy, and 30.4% were not seen. 5. In the change of tooth, 59.1% were intact, 18.2% were loss of the alveolar lamina dura, 13.6% were root resorption 4.55% were tooth displacement, 4.55% were root resorption and tooth displacement. 6. In the change of cortical bone of the solitary bone cyst, 39.1% were intact and 60.9% were thinning and expansion of cortical bone. 7. In the histopathologic findings of 9 cases, 33.3% were thin connective tissue wall, 11.1% were thickened myxofibromatous wall, 55.6% were thickened myxofibromatous wall with dysplastic bone formation.

Chondroblastoma is a rare benign tumor that produces giant cells and cartilage matrix. The tumor occurs in people between 10 and 25 years with slightly higher incidence in males. The condition occurs in the proximal epiphysis of the tibia and humerus, distal epiphysis of the femur, but its occurrence in the talus is relatively rare, accounting for 4% of the total number of chondroblastoma cases. Chondroblastoma is often misdiagnosed as a primary aneurysmal bone cyst, giant cell tumor, chondromyxoid, and lesion of a secondary aneurysmal bone cyst by fibrous dysplasia. The most commonly used surgical method for chondroblastoma is broad curettage with bone grafting. In general, an aneurysmal bone cyst is associated with a second degree chondroblastoma, which is approximately 20%. Chondroblastoma of the talus and secondary aneurysmal bone cysts can be misdiagnosed as primary aneurysmal bone cysts. This paper reports a case of a young male patient with chondroblastoma of the talus, which was initially misdiagnosed as an aneurysmal bone cyst with involvement of the talo-navicular joint.

Aneurysmal bone cysts of rib continue to interest the clinicians because of their rarity. We experienced a case of aneurysmal bone cyst of Rt 10th rib, which was occupying the Rt pleural cavity as a huge mass. This case was treated surgically with good result. In addition, general concept of aneurysmal bone cyst with brief review of literatures was disclosed here.

Stafne 골낭종은 악하선의 발생 시 생긴 하악골의 결손부로 주로 하악골의 후방부나 하악 우각부에 발생한다. 대부분 하치조 신경관 하방에 발생하며 하악골 전방부에 발생하거나 하악 치아와 연관된 경우는 드물다. 또한 하악골의 천공을 일으키는 경우는 더욱 드물다. 본 증례는 하악골 전방부에 발생하여 하악골 천공을 일으킨 치근단낭과 유사한 병소가 stafne 골낭종으로 진단된 희귀한 증례로, 이와 유사하게 하악골에 발생 가능한 병소의 감별 진단과 함께 보고하고자 한다.

Fibrous dysplasia is a benign fi bro-osseous lesion wherein normal bone is replaced with an excessive proliferation of cellular fibrous connective tissue intermixed with irregular bony trabeculae. Fibro-osseous lesions like fibrous dysplasia are often associated with non-epithelial cysts, such as simple bone cyst. The etiologic and pathogenic relationships between fi brous dysplasia and simple bone cyst have not been conclusively established. Nonetheless, the mechanism of cyst formation in fibro-osseous lesion associated with simple bone cyst can be said to differ from that of the typical simple bone cyst of the jaws. This article reports a case of bilateral lesions including fi brous dysplasia and simple bone cyst on each site and reviews the pathogenesis of cyst formation in the fibro-osseous lesion.

We report a rare case of fibrous dysplasia with the development of a secondary aneurysmal bone cyst presenting as solitary tumor of calvarium. Although fibrous dysplasia with aneurysmal bone cyst is rare, it should be taken into account in differential diagnosis of the osteolytic solitary skull lesion.
