Bronchogenic cysts are congenital malformations of the bronchial tree, a type of bronchopulmonary foregut malformation. The presentation of the bronchogenic cyst is variable, making pre-operative diagnosis difficult. They aremostly asymptomatic orarefound incidentally when the chest is imaged. They can present as lower neck massesor mediastinal masses that may enlarge. They cause mass effect due to local compression and may result in tracheo-bronchial obstruction leading to air trapping and respiratory distress. The treatment is somewhat controversial, and in general,these lesions are treated using the transcervical or transbronchial approach. When these cysts arelocalized in the upper mediastinum, it may be possible to removethemusing the transcervical approach. In our three cases, the patientscomplained of mild dysphagia, foreign body sensation, and dyspnea. We report three cases of a large bronchogenic cyst in the lower neck and the upper mediastinum treated using the transcervical approach.

Cystic hygroma remains a complex entity in terms of its development and management. Most recently, cystic hygroma has been categorized as part of a larger spectrum that include lymphangioma. The majorities of lymhangioma occur in the head and neck as cystic hygromas with the posterior cervical region as the most common site. Cystic hygromas usually present in infancy or early childhood as compressible masses that may rapidly and intermittently enlarge. While they may arise in any anatomic location, hygromas of the head and neck are especially difficult and speech pathology. Since as airway obstruction, feeding difficulties, and speech pathology. Since its original description, there have been many attepmts at treatment modalities : surgical excision remains the treatment of choice. Complete extirpation of these lesions is often impossible, and recurrence rates are accordingly high. This is report of a case bout 5-year-old female patient with cystic hygroma, resulted in facial asymmetry and swallowing difficulty, in left submandibular area. We obtained the successful functional and esthetic results by simple surgical excision of tumor mass. Therefore, we represents the case with literatural reviews.

A dentigerous cyst is the most common developmental odontogenic cyst. Patients with dentigerous cyst usually feel no pain or discomfort. If it is not treated, tooth eruption might not only be impeded, but also let the tooth translocate to the unusual area. So, early detection and appropriate treatment are important. Enucleation & marsupialization are the best options to treat a dentigerous cyst. Treatment plan depends on patient's age, health, preserve & protect of important structures, and sort of cyst. In these dentigerous cysts cases, by marsupialization and using obturator, affected tooth could be achieved spontaneous eruption into the dental arch even though they were badly dislocated.

Fetal cystic hygroma is a rare congenital malformation of the lymphatic system appearing as a single or multiloculated fluid-filled cavity, most often in the neck, A case of fetal nuchal cystic hygroma was diagnosed by ultrasonography at 22 weeks of gestation and the diagnosis was confirmed at autopsy. We present the case with a brief review of literature.

This study was performed for the purpose of providing basic data of the pelvic disorders through survey of the frequency of management of occurrence by major risk factor. Female pelvic mass was detected using sonography, and necessary data were collected from 604 female visitors to a obstetrics and gynecology hospital located at S-si. Female pelvic mass was uterus mass, ovarian mass, cervical cyst, endometrial disease. For the analysis, such variables as age, weight and frequency of pregnancy were chosen as risk factors. Results of the analysis and conclusions are as follows ; 1) The frequency of occurrence of the female pelvic mass is highest, as 38.9% of the component ratio, in the age of 35 to 54. It maintains high level of 35.8% even in the age of 55 and above. 2) The frequency of occurrence of the female pelvic mass increases in proportion as the weight and frequency of pregnancy increase. 3) The size of the uterus tumor has no statistical relationship with the risk factors, age, weight and frequency of pregnancy.

Background: Tuberculous cervical lymphadenitis can be diagnosed by clinical findings, chest X-ray, Mantoux test, but confirmed only by excisional biopsy. The polymerase chain reaction(PCR) is now widely applied to test very small amount of pathogen and would be used to detect Mycobacterium tuberculosis in biopsied tissues and fine needle aspirates. Method: We carried out the PCR using IS-1 and IS-2 primers in 16 samples from tuberculous cervical lymphadenitis patients, and 13 samples from non-tuberculous cervical lymphadenopathy patients. Acid fast staining and culture for Mycobacterium were all negative. Results: All of 8 pathologically confirmed tuberculous cervical lymphadenitis samples showed positive PCR results, and of 5/8 clinically diagnosed samples were positive. None of 6 pathologically excluded samples were positive, and among 7 clinically undiagnosed samples 2 showed positive PCR results. Conclusion: In patients with suspected tuberculous cervical lymphadenitis, PCR could be used to detect Mycobacterium tuberculosis using biopsied tissues and even fine needle aspirates with good sensitivity and specificity.

Cystic lymph node metastasis of head and neck squamous cell carcinoma(HNSCC) which presumed to be mainly originated from oropharynx including Waldeyer's ring may present as a benign cystic mass on lateral neck such as branchial cleft cyst. Branchial cleft cyst is one of the most common lateral neck cystic mass which may result in regional infection or lymph adenopathy. Many of previously reported literatures showed the incidence of cystic lymph node metastasis from oropharynx including Waldeyer's ring. Preoperative imaging studies and fine needle aspiration cytology cannot provide the accurate results until excision of cystic mass for the diagnostic or therapeutic purpose. Recently, we experienced the rare case of cystic lymph node metastasis from ipsilateral tonsil, which mimicked infected 2nd branchial cleft cyst. Thus, we reported our experience with presentation of case and review of literatures.

Foregut cystic developmental malformations are rare developmental anomalies. It is important to diagnose the diseases and manage them properly because these cysts may generate feeding or respiratory difficulties depending on the size and location of the lesions. A newborn was referred for a congenital cervical swelling to our clinic on the second day of his life. Neck SONO and MRI showed an about 6cm sized cystic mass at left submandibular area. Aspirations and sclerotherapies were done repeatedly due to recurred cystic mass. Under the suspicious of cystic hygroma, the mass and submandibular gland were excised. Histologically, it was a benign cyst including gastrointestinal and bronchogenic mucosa and pancreatic tissue. Foregut cyst was suggested for the final diagnosis and the patient was discharged at 9 days after the operation without a complication. He has visited our out-patient department. Although several image studies have been introduced to find out foregut cyst, it is difficult to go through differential diagnosis because of similarity of other benign tumor. Further studies for early diagnosis of cervical foregut cyst are needed for preventing possible related problems.

Cystic lymphangioma is also called cystic hygroma, and it usually appears in the cervico-facial and axillary regions. It is usually apparent at birth and 90% of the cases appear at the end of second year. We have experienced a 64 year-old-male who had a large cystic lymphangioma in the left posterior chest wall. Surgical excision was done, and his postoperative course was uneventful. He has been well for two years postoperatively.

An intrathyroid thyroglossal duct cyst (TGDC) presented as an anterior neck mass in a 62-year-old male without history of prior thyroid disease or infection. This cyst was clinically indistinguishable from a thyroid nodule. In addition to that, fine needle aspiration cytology revealed normal-looking squamous cells. Diagnosis, work-up, management approach, and treatment of intrathyroid TGDC are discussed as well as distinguishing features between intrathyrod TGDC with tract and without tract. This is the very rare case of intrathyroid TGDC in Korean population and the possibility of intrathyroid TGDC should remain in the differential diagnosis of thyroid nodule.
