One hundred fifty four cases of branchial anomaly treated from January 1987 to July 1993 were analysed to determine clinical features, embryologic and anatomic types of the branchial cleft anomaly, to investigate the differences between adults and pediatrics, and to establish the appropriate treatment plan. The male to female ratio was not signifiacntly different in pediatric and adult patients. The mean symptom duration was 0.5 years(range 0.08-14 years) in pediatric patients and 1.67 years (0.7-7 years) in adult patients. The clinical presentations of these anomalies were lateral neck mass in 112(72.7%), infected discharge in 22(14.3%), non-infected discharge in 6(3.9%), and abscess in 14 cases(9.l%). Sites of the lesions were upper third of the neck in 93(60.3%), infraauricular in 35(22.7%), middle third of the neck in 17(11.0%) and inferior third of the neck in 9 cases(5.8%). The anatomic types were cystic form in 117(75.9%), sinus in 24(15.5%), and fistula in 13 cases(8.4%). Embryologic classification were 124 second branchial cleft anomalies(80.5%), 29 first branchial cleft anomalies(18.8%), and 1 third branchial cleft anomaly(0.6%). Immediate surgery under the uncontrolled infection in 17 cases result in 82.4% recurrent rate(14 cases), and 17.6% cure rate(3 cases). Delayed surgery under the controlled infection in 8 cases recurrent rate(1 case), and 87.5% cure rate(7 cases). In summary, the most common branchial cleft anomaly is second type cyst both in pediatric and adult group, delayed surgical exterpation after infection control with I & D or antibiotics may give a good chance for care and may reduce the recurrence.

Branchial cleft cysts are most common neck masses in adults. Most are second branchial cysts, which occur in the neck, anterior to sternocleidomastoid muscle at the mandibular angle. Rarely these cysts may be present in the parapharyngeal space. We report a case of a second branchial cleft cysts in the parapharyngeal space of 32-year-old female, which was misdiagnosed as peritonsillar abscess. It was excised via transoral and transcervical approach.

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.

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.

Branchial cleft cyst is the most common lateral neck cyst; the vast majority are of the second branchial cleft origin. This presumably reflects the greater depth and longer persistence of the second cleft, compared with the first, third, and fourth clefts. We experienced a 49-year-old male whose chief complaint was a abnormal mass of the left parotid gland area and neck. As a result of careful analysis of clinical, radiological, and histopathological findings, we diagnosed it as a second branchial cleft cyst in the neck and obtained results as follows: 1. In clinical examination, there was a 10×15㎝ sized, fluctuant painful mass in the left neck and parotid area. 2. In radiographic examination, a low echogenic mass with internal cystic change in the inferior parotid gland area was noted sonographically. Computed tomograph showed a 3×4㎝ sized, well-defined cystic mass with heterogenous solid component in the anterior border of sternocleidomastoid muscle. MRI revealed 5×6㎝ sized, well-marginated multi separated mass in the same area. 3. In histopathological examination, lining of cyst was stratified squamous epithelium with typical lymph node pattern and inflammatory cell infiltration.

Branchial cleft cyst is rarely encountered congenital neck disease. It is commonly believed that the branchial anomaly is persistance of remnant of the embryologic branchial apparatus. Among the patients visited Kyung Hee Medical Center with neck mass and inflammatory sign from January, 1980 to Aprial, 1994, we reviewed 26 cases of branchial cleft cysts confirmed by histopathologic findings with retrospective study on clinical aspects. The results are as follows: 1) There was no sex difference(14 male and 12 female), and most common between 2nd and 4th decade(21 cases, 80%). 2) Palpable mass was most common complaint(21 cases). In physical exam, the mass was non-tender, mobile and soft in most cases(over 80%). 3) The most common lesion site was anterior triangle in 15 cases. Along the SCM level, 21 cases were in upper 1/3, 2 cases in middle 1/3 and 3 cases in lower 1/3. 4) According to Bailey's classification, type II were 20 cases(76.9%), type I 5 cases(19.2%) and type III 1 case. 5) Among 28 cases, fistulous tract was found in 6 cases: one was complete type and 5 were incomplete type. 6) Among 26 cases before operation, 10 cases were diagnosed as branchial cleft cyst, 6 cases tuberculosis, 3 cases parotid tumor and 2 cases thyroglossal duct cyst. 7) Type of lining epithelium in histopathologic finding was stratified squamous epithelium in 22 cases(84.6%), mixed type in 4 cases(15.4%).

The fourth branchial clef cyst is very rare entity ana only 35 cases have been reported worldwide. There have been some controversial attempts to prove its anatomical route through embryological background. However some reports even suggested that it might be impossible to prove its entity anatomically Recently, reports are coming out on the diagnostic approaches using anatomical pathway. We experienced in 45 years old woman, one case of lateral cystic neck mass which were anatomically presumed to be fourth brachial cleft cyst.

In branchial lymphoepithelial cyst (BLEC), which is also known as branchial cleft cyst, the remnants of a branchial arch develop into a cyst, causing swelling. The first case of BLEC in the parotid gland was reported by Hildebrant in 1895. Since then, BLEC in the parotid gland has continued to be reported, but in rare cases. A 45-year-old man presented to our hospital with a swelling of the left cheek of approximately 6 months' duration. The patient underwent a superficial parotidectomy and was pathologically diagnosed with BLEC. Of note, this was the first case of non-human immunodeficiency virus (HIV)-related BLEC of the parotid gland in South Korea. BLEC is a benign condition, but its treatment depends on the presence of HIV infection. In HIV-negative patients, BLEC does not require a further work-up to evaluate metastasis. Our case report describes the diagnosis and treatment of BLEC in a patient without HIV.

Our case presents unusual case of Bilateral second brachial cleft fistulas The brachiogenic anomalies usually arise from an imcomplete obliteration of branchial appartus are common congenital cervical anomalies. But Bilateral manifestation are very rare. We treated it with surgical excision and it has not occurred recurrence until now. So we report about its character and treatment of Bilateral second brachial cleft fistulas.

Developmental anomalies arising from the branchial apparatus include cysts, external sinuses, internal sinuses, and complete fistulas. Second branchial cleft cysts are by far the most common among these anomalies. It may occur at any age, being most common in the third decade, and more frequent in the male than in the female. It usually presents a smooth, round, nontender fluctuant mass located between the level of the tragus and the clavicle along the anteromedial border of the sternocleidomastoid muscle. It is lined by respiratory or squamous epithelium unless inflammation is present. The considerable amount of lymphoid tissue may be found beneath the epithelium. The treatment of choice of branchial cleft cyst is surgical excision. If the lesion is acutely infected, however, it is essential to relieve the infection prior to the surgery. This report deals with two cases of second branchial cleft cyst. In case 1, the cyst had rapidly increased in size over pregnant period. In case 2, the patient presented the swelling in the left neck, and had the history of incision and drainage because of misdiagnosis as submandibular space abscess. The infection was treated by antibiotic therapy in the first place, and then complete surgical excision was made. There was no evidence of any recurrence or complications for these $3{\sim}4$ years.
