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.

Traumatic bone cyst is a nonodontogenic cyst without epithelial-linig which contains fluid in it's cavity, and it is limited by bone walls with no evidence of infection. Traumatic bone cyst is asymptomatic and appears more frequently in the second decade. Gender distribution is approximately equal, although males are affected slightly often than females. Radiographically the lesion shows a well demarcated radiolucent lesion of variable size and the lesion may have scalloped margins. The adjacent teeth to traumatic bone cyst remains vital. Traumatic bone cyst is usually treated by surgical exploration and currettage of the lesion. In the first case of this case report, the patient was refered from the local dental clinic for the radiolucent area under the left mandibular first molar. From the panorama radiograph at the first visit, the radiolucent area of the left mandible showed a well defined scalloped margin and identified as traumatic bone cyst. In the second case, the patient have visited for the chief complaint of swelling and abcess of right maxillary second premolar. In the radiographic check up with panorama radiograph, the radiolucent lesion with well demarcated scalloped margin was found in the right mandible body, and identified as traumatic bone cyst. In the first case, overinstrumentation was done through the mesial root canal to irrigate the lesion. In the second case, not any treatment was done, and watched the progression of the lesion. And in both cases, after two month, the radiolucency and the size of the lesion has decreased to show healing in progress.

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 bone cyst (SBC) is a bone defect usually located in the posterior portion of the mandible or mandibular angle below the inferior alveolar nerve. The cases of SBC involving multiple anterior tooth apices and penetrating the mandibular bone are extremely rare. Here we present a case of an anterior-positioned SBC mimicking periapical cyst, which penetrated the mandibular bone, with a review of the differential diagnosis.

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.
