  • Purpose : A cyst-like lesion within and around the knee joint is very rare, with very few articles available in the literature. The aim of this study is to evaluate effectiveness of arthroscopic treatment of cyst-like lesion within and around the knee joint which reported rarely. Materials and Methods : We are reporting 14 cases of cyst-like lesion around the knee joint. Our cases include 3 ganglion cyst in infrapatellar fat pad, 1 fibroma, 1 giant cell tumor and 1 epidermoid cyst which have not yet been reported. The diagnosis of cyst-like lesion in Juxta-articular knee Joint was made only by MRI study and we confirmed pathology. Male was 9, female was 5 cases, average age was 24(11-43)year old. Follow up was average 45(12months-8years)months. Minimum follow up was 12 months. Results : All the patients were treated arthroscopic excisional debridements successfully. All the cases were excellent result in last follow up by functional criteria in Lysholm knee score average 98.9(95-100). All examimation was normal except 3 cases in last follow up. But all patients satisfied in arthroscopic treatment. Conclusion : Arthroscopic excisional debridement of the cyst-1ike lesion in juxta-arthcular knee joint is excellent method, but long term follow up needed in the future.

  • A rare case is described of an intrathyroidal branchial cleft-like cyst in neonate. The patient was a newborn girl with a mass in the left lateral neck. The ultrasonography and computed tomography revealed a cystic lesion in the left thyroid. The lesion was enucleated surgically from the thyroid. Histologically, the cyst was lined by squamous or columnar epithelium and contained inflammatory cell infiltraion, thyroid and parathyroid tissue. The patient has been doing well without any evidence of thyroid dysfunction for 15 months.

  • 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.

  • 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.

  • The glandular odontogenic cyst is a rare lesion described in 1987. It generally occurs at anterior region of mandible in adults over the age of 40 and has a slight tendency to recur. Histopathologically, a cystic cavity lined by a nonkeratinized, stratified squamous, or cuboidal epithelium varying in thickness is found including a superficial layer with glandular or pseudoglandular structures. A 21-year-old male visited Dankook University Dental Hospital with a chief complaint of swelling of the left posterior mandible. Radiographically, a huge multilocular radiolucent lesion involving impacted 3rd molar at the posterior mandible was observed. Buccolingual cortical expansion with partial perforation of buccal cortical bone was also shown. Histopathologically, this lesion was lined by stratified squamous epithelium with glandular structures in areas of plaque-like thickening. The final diagnosis was made as a glandular odontogenic cyst.

  • More than half of patients presenting with hoarseness show benign vocal cord changes. However, in rare cases with benign mucosal lesions, it can be diagnosed as a malignant disease after histopathological examination. A 53-year-old man with a 30-pack-year smoking history was admitted for the evaluation of hoarseness, and using a laryngoscope, an enclosed, sac-like cystic lesion was detected on the midpoint of the right true vocal cord. The cystic lesion was deemed to be an intracordal cyst and treated with laryngeal microsurgery. However, pathological findings showed squamous cell carcinoma of the larynx arising in the intracordal cyst, which is exceptionally rare. Therefore, even if a benign lesion is initially suspected, a biopsy must be performed on a patient with smoking history to confirm the diagnosis. In conclusion, we report a case of squamous cell carcinoma of the larynx arising in the intracordal cyst.

  • 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.

  • Bronchogenic cysts are thought to be uncommon developmental anomalies. They develop from small buds or diverticuli that separate from the foregut in the formation of the tracheo-bronchial tree. They are nearly always located near the tracheal bifurcation; However, these lesions can occur anywhere along the tracheo-bronchial tree. We experienced a case of cervical bronchogenic cyst presenting sorely as an anterior neck mass in a 26-year-old woman. The neck ultrasonography showed as $1.4{\times}1.1cm$ sized hypoechoic lesion with a well-defined margin on the isthmic portion of the thyroid gland. Excision of the mass was carried out. The mass was superfical to the strap muscle and was contained within the subcutaneous tissue in the midline without any connection to the trachea. Grossly, the mass was an oval-shaped cystic lesion which measured 1.5 cm in the greatest diameter. The cyst was filled with thick, yellow, jelly-like material and the inner surface was smooth and glistening. Microscopically, the cyst showed a lining of ciliated columnar epithelium, beneath which was a loose areolar stroma containing plaques of mucous glands and mature cartilage. We thought this cervical bronchogenic cyst appeared to represent an expression of complete aberrent accessory lung bud detachment from the primitive foregut.

  • A case of a botryoid odontogenic cyst of the globulomaxillary area between the right upper lateral incisor and the canine presenting as an apical periodontal cyst was reported. The cyst showed an unilocular radiolucency with a well delineated hyperostotic border. Histologic examination revealed multiple cysts lined by one or two-cell layers, some areas demonstrated a bud-like thickening of the epithelium. Clear cells were also conspicuous, but devoid of inflammatory reaction in the cystic wall. Some considerations regarding differential diagnosis, histogenetic and biologic behaviour of the lesion were discussed.

  • The aneurysmal bone cyst is a nonmalignant reactive bone lesion. Developing rarely in the craniofacial region, and more commonly affecting the long bones and the spine, the lesion has variable etiopathogenic characteristics. The authors diagnosed a 33-year-old female as aneurysmal bone cyst after undergoing clinical, radiological and histological examinations. The characteristics were as followed: 1. The patient complained of pain and swelling of the right preauricular area. 2. The conventional radiograms showed a relatively well defined radiolucent lesion with partially scalloping margin. The cortical bone of the right condyle was thinned and expanded by the lesion. 3. Bone scintigraphy with ~c demonstrated ring-like or doughnut-pattern accumulation of radioactivity. 4. On Tl-weighted imaging of MRI, the lesion on the right condyle had middle signal intensity. T2-weighted MRI demonstrated multiple high signal intensities seperated by septa which had low signal intensity. Finger in balloon appearance was seen. 5. Histologically, the lesion was composed of large sinusoidal blood spaces lined by fibroblasts and histiocytes. Its fibrous stroma consisted of fibroblstic element, multinucleated giant cells, extravasated erythrocytes and focal hemosiderin pigmentation. New bone formation was also observed around larger sinusoidal spaces.
