The survey on branchial anomalies was conducted by Korean Association of Pediatric Surgeons. A total of 173 cases were reported, which were managed by 36 members and cooperators during the three years from January 1, 1993 through December 31, 1995. The following results were obtained by retrospective analysis of the 173 cases of branchial anomalies. The presenting symptoms were cervical mass in 101 cases, pit with or without discharge in 71, cervical abscess in 47 and respiratory difficulty in 3. The average age of the patients with cervical abscess was 52 months. Seventy(79%) of 89 patients with branchial anomalies and a cystic mass had their first clinical manifestations by 1 year of age, while 40(51%) of 78 patients with only a branchial cyst had their first clinical manifestation in first year of life. Radiologic studies were carried out in 77 patients (43%). The preferred diagnostic modalities were ultrasonography(47 patients), simple neck radiogram(19) and CT scan(17). Preoperative diagnosis was correctly made in 156(91%) of 173 patients. Seventeen patients were incorrectly diagnosed as thyroglossal duct cyst in 5 patients, cystic hygroma in 4, dermoid cyst in 3, and lymphadenopathy in 3. There were no remarkable difference in sex and laterality of presentation but bilateral lesions were found in 9(5%) patients and unusual locations of the anomalies were the manubrium, left subclavicular area, median cervial area, preauricular and parotid area. There were 78(45%) patients with cyst, 52(30%) patients with sinus, 35(20%) patients with fistula and 8(5%) patient with skin tag. Embryological classification was possible in only 64(37%) patients. The 2nd branchial anomaly was present in 50(78%), the 1st branchial anomaly in 10(18%), and the 3rd or 4th branchial anomaly in 4(6%). Histopathological study of the lining epithelium(N=134) is recorded that 45% were lined with squamous epithelium, 17% with respiratory epithelium, 6% with. squamous and respiratory epithelium, 14% with inflammatory change. Lymphoid tissue was common(62%) in the wall of the lesions. Twelve(7%) of 158 patients had postoperative complications including wound complication, recurrence and facial nerve palsy.

A thyroglossal duct cyst (TGDC) is the most common congenital anomaly of the neck. However, carcinoma arising from TGDC is extremely rare. We report 2 cases of TGDC carcinoma. In the first case, a 21-year-old male patient complained of an anterior cervical mass; computed tomography (CT) and sonography revealed cystic mass that was suspected to be a TGDC. Sistrunk operation was performed. Papillary carcinoma was confirmed in pathologic examination. Additionally, he underwent total thyroidectomy and central neck dissection. After radioactive iodine ablation (RAI) was performed. In the second case, a 28-year-old male patient visited our out-patient department complaining of submental mass. He had already been diagnosed TGDC carcinoma 13 years ago and had undergone Sistrunk operation and total thyroidectomy. Malignancy was confirmed using fine-needle aspiration; thus, lateral neck dissection was performed and following this, he underwent RAI. Till date, no evidence of recurrence has been observed in these patients.

One of the most common sources of spinal pain syndromes is the facet joints. Cervical, thoracic, and lumbar facet joint pain syndromes comprise 55%, 42%, and 31% of chronic spinal pain syndromes, respectively. Common facet joint disorders are degenerative disorders, such as osteoarthritis, hypertrophied superior articular process, and facet joint cysts; septic arthritis; systemic and metabolic disorders, such as ankylosing spondylitis or gout; and traumatic dislocations. The facet pain syndrome from osteoarthritis is suspected from a patient's history (referred pain pattern) and physical examination (tenderness). Other facet joint disorders may cause radicular pain if mass effect from a facet joint cyst, hypertrophied superior articular process, or tumors compress the dorsal root ganglion. However, a high degree of morphological change does not always provoke pain. The superiority of innervating nerve block or direct joint injection for diagnosis and treatment is still a controversy. Treatment includes facet joint injection in facet joint osteoarthritis or whiplash injury provoking referred pain or decompression in mass effect in cases of hypertrophied superior articular process or facet joint cyst eliciting radicular pain. In addition, septic arthritis is treated using a proper antibiotic, based on infected tissue or blood culture. This review describes the diagnosis and treatment of common facet joint disorders.

Metastatic squamous carcinoma of the head and neck may rarely present as a cyst in the cervical region. The true incidence of metastatic cystic neck mass is unknown. It is difficult to differentiate metastatic cystic neck mass from congenital cystic neck mass with physical examination and fine needle aspiration biopsy. So the differential diagnosis is dependent on the age of the patient, and therefore in the patient over the 40 years of age, the possibility of a metastatic neck mass should be considered. We report a metastatic cystic neck mass which had been misdiagnosed as a branchial cleft cyst.

Thyroglossal duct cysts (TGDC) are the most common type of congenital developmental anomaly encountered in the anterior midline of the neck in childhood. The aim of the study was to evaluate the clinical characteristics of TGDC and identify any factors that could be related to recurrence after surgery. This study consisted of a retrospective chart review of 45 patients treated at Kyungpook National University Hospital for TGDC between 1990 and 2008. All records were reviewed for age and sex, length of history, presentation, diagnostic methods, sizes and locations of cyst, surgical management, histopathology of the lesion and recurrences. The statistical analysis of risk factors for recurrence was made using the Fisher's exact test with a significance level of p (0.05. The male to female ratio was 2.2:1 with a male preponderance. The mean age at operation was 5 years and 2 months (4 months - 17 years). The most common presenting symptom was a nontender cervical mass (78 %). Most TGDC were found in the midline position. Twenty four were infrahyold, 17 were hyoid, and 4 were suprahyoid level. Forty one (91 %) patients received the Sistrunk operation, and 4(9 %) patients received Cyst excision. Postoperative a seroma developed in six patients in the early postoperative days. There were a total of 3(6.6 %) recurrences, 2 in patients who had excision only and in one patient who had the Sistrunk operation. Univariate analysis for risk factors with recurrence showed that there was no statistical relationship between the presence of preoperative infection and the development of recurrence. The removal of hyoid bone along with TGDC was a statistically significant risk factor for recurrent disease. This study suggests that the Sistrunk operation Is the treatment of choice for TGDC in order to reduce recurrence.

Purpose: Whereas oral ranula is relatively common and presents as a cyst in the mouth, the plunging ranula is rare and manifests itself as a mass in the neck with or without an associated oral lesion. The purpose of this study is to examine the clinical characteristics of rare bilateral plunging ranula arising from accessory submandibular gland in order to provide our experience for its correct diagnosis and treatment. Methods: A 13-year-old girl manifests as a slow growing painless, non-mobile swelling in the anterior neck. She underwent surgery via a cervical approach. A pseudocyst was extirpated and adjacent accessory gland tissue and related lymph node were removed. Results: The histologic appearance is characteristically of a cyst, devoiding of epithelium or endothelium, with a vascular fibro-connective tissue wall containing some chronic inflammatory cells and macrophage stuffed with mucin. Pathologic findings represented a form of myxomatous degeneration and lined by condensed connective tissue and granulation tissue. The nature of the accessory gland tissue was same as subligual gland. Although total submandibular or sublingual gland excision was not performed, no recurrence was observed during 6 months follow-up periods. Conclusion: Usually, unilateral plunging ranula develops commonly because of rupture of sublingual gland duct by trauma and extravasation of salivary secretion to the adjacent tissue. But our case developed because of bilateral congenital accessory submandibular gland. This is thought to be a result from a congenital failure of canalization of the terminal end of the duct. Finally, the correct diagnosis is essential for the most effective treatment, which is excision of the ranula and related accessory salivary gland. We performed excision of accessory submandibular gland and plunging ranula and had a good result without recurrence.

Hemangioblastomas are rare benign tumor of the central nervous system that commonly occur in the posterior fossa around the 4th ventricle. In case of von Hippel-Lindau disease, hemangioblastomas involve multiple regions such as cerebellum, spinal cord and brainstem but, rarely show simultaneous involvement of cerebellum and spinal cord. We have experienced a case of multiple hemangioblastomas that were located at the cerebellum, cervical cord and conus medullaris and also had multiple lesions that a part of von Hippel-Lindau disease ; retinal angioma, syringomyelia, multiple cyst on kidney and pancreas, renal cell carcinoma on left kidney. Hemangioblastomas on cerebellum and spinal cord were removed totally, retinal angioma was treated with laser photocoagulation and renal cell carcinoma was also totally excised. The authors report a case of von Hippel-Lindau disease had multiple located hemangioblastomas on cerebellum, cervical cord and conus medullaris with review of literature.

Spinal schwannomas are usually extramedullary intradural tumors and their intramedullary localizations are thought to be extremely rare. A 60-year-old woman complaining spastic quadriparesis, voiding difficulty and dyspnea was admitted. Her cervical MRI revealed an intramedullary mass in the cervicomedullary junction with multiple cyst which extended from lower cervical to C3 spinal cord. The mass showed a low signal on T1WI, high signal on T2WI with an wall enhancement. The patient underwent a suboccipital craniectomy and C1-2 laminectomy and the cystic tumor was totally removed through a midline myelotomy. The tumor was proved as an intramedullary schwannoma by pathologic examination. The Intramedullary presence of a tumor arising from the cells of the nerve sheath is unusual, because the central nervous system fibers do not contain the Schwann cell. There have been several hypotheses, but none has been accepted universally. This rare tumor is considered as a curable benign neoplasm, and an accurate intraoperative diagnosis and surgically total removal are essential.

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.

Branchial cleft anomalies are the second most common head and neck congenital lesions seen in children. Amongst the branchial cleft malformations, second cleft lesions account for 95 % of the branchial anomalies. This article analyzes all the cases of second branchial cleft anomalies operated on at Seoul National University Hospital from September 1995 to February 2011. We analyzed sex, age, symptom and sign, accompanied anomaly, diagnosis, treatment, pathologic report and outcome via retrospective review of medical records. In this series, we had 61 patients (27 female and 34 male). The mean age at the time of operation was 38 months. 31 lesions were on the right, 20 were on the left and 10 were bilateral. The most frequent chief complaints at presentation were non-tender mass and cervical opening without any discharge. According to anatomic type, 29 patients had branchial cleft sinuses, 14 had cysts, 14 had fistulas and 4 had skin tags. Complete excision was attempted if possible and antibiotics challenged when infection was suspected. Complete excision was achieved in 96.7 % of cases. Incision and drainage was done in 2 cases due to severe inflammation, and both recurred. Postoperative complications included wound infection in 2 cases. Microscopic examonation revealed squamous epithelium in 90.2 % and squamous metaplasia in one case in the branchial cleft cyst wall. In summary, second branchial anomaly is found more frequently on right side of neck. Fistulas are diagnosed earlier than cystic forms. Most cases could be diagnosed by physical examination. The definitive treatment is complete excision and sufficient antibiotics coverage for cases with inflammation. After drainage of infected lesions, follow up excision after 1 year might be beneficial for preventing recurrence.
