구순구개열은 두경부에서 가장 흔히 발생하는 선천적 기형 중 하나로 554명 중 1명의 빈도로 나타나며 인종에 따라 다양하다. 구순구개열 환아들은 다른 선천적 기형을 동반하여 나타나는 경우가 흔하며, 그 빈도는 문헌에 따라 다르지만 1.5~63.4%로 나타난다. 새열낭종은 두번째 인두강의 폐쇄부전으로 나타나는 선천적 결손으로, 주로 흉쇄유돌근 전방에 나타난다. 구순구개열 환자에 있어 새열낭종을 동반하는 경우는 매우 드물다. 전북대학교 구강악안면외과학 교실에서는 새열낭종을 동반한 구순열 환아 1례를 경험하였다. 환아는 우측 불완전 편측성 구순열로 내원하여, 구순성형술과 함께 우측 목에 존재하던 새열낭종에 대한 제거 수술을 시행하였다. 환아는 출생 당시부터 심실중격결손 및 동맥관개존증 등의 선천적 심장질환 및 갑상선 기능저하증을 가지고 있던 환아로 다양한 선천적인 결손을 동반한 본 환아의 증례를 문헌고찰과 함께 보고하는 바이다.

Branchiogenic carcinoma is extremely rare and is defined as a malignant degeneration within the confines of epithelial remnants derived from the embryonal branchial apparatus. Two major diagnostic criteria are histologic proof of transitional area from normal cyst epithelium to invasive squamous cell carcinoma and absence of an identifiable primary carcinoma elsewhere. A 62-year old woman visited our department complaining of a non-tender, movable mass in left upper lateral neck. After a complete mass excision, histopathologic diagnosis of the surgical specimen was branchiogenic squamous cell carcinoma. I report a case of branchiogenic carcinoma with literature review.

The existence of primary branchiogenic carcinoma is controversial. In 1950, Martin et al. established four criteria for the diagnosis of primary branchiogenic carcinoma. In 1989, Khafif et al. proposed new modified criteria, which are currently most recognized in the literature. A 54-year-old woman presented the well-defined, fluctuant, painless mass on her left neck and underwent a complete excision under the clinical diagnosis of the branchial cleft cyst. The initial pathological impression was a branchiogenic squamous cell carcinoma. However, it did not coincide with a true primary branchiogenic carcinoma clinically. After the guided biopsy of suspicious areas found a squamous cell carcinoma of the tongue base, the patient was treated by combination chemotherapy with radiotherapy. Thus, we report this case with a review of the literature.

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.

In case of lateral cervical cystic lesions, the differential diagnoses include branchial cleft cyst(BCC), teratoma, dermoid, hemangioma and lymphangioma etc. But sometimes metastatic cystic lymph nodes may exist in lateral neck. In such circumstance, the primary lesions are known to stem from oropharynx, nasopharynx, salivary and thyroid gland etc. A-66-year-old-male came to our clinic, due to the lateral cervical mass for 5 years. We performed the neck CT, sonography and sono-guided FNAC. He was initially diagnosed with the benign cyst such as BCC. We performed the excisional biopsy on left level II, but the pathologic report was revealed as metastatic papillary thyroid carcinoma(PTC). And then he received the total thyroidectomy with neck dissection. The final diagnosis was cystic metastasis from PTC. We learn a valuable lesson form this case in the following. Even if the simple cervical cyst is presumed with radiology and clinical pattern, more careful considerations on the basis of history and radiologic findings are mandatory.

Branchial cleft cysts typically are characterized as lateral swellings anterior to sternocleidomastoid muscle in upper third of the neck. However, cysts have been reported in unusual location such as the thymus, oral cavity, parotid gland, pancreas, and thyroid. Perithyroidal branchial cleft cysts are also rare and preoperative diagnosis is very difficult. Recently we have experienced a case of intrathyroidal branchial cleft cys and a case of perithyroidal branchial cleft cyst, which were diagnosed preoperatively as the parathyroid cyst. So, we report these two cases with review of the literatures.

Background and Objectives : Fourth branchial cleft cyst is a rare congenital anomaly which cause a recurrent cervical abscess. Complete excision of fourth branchial cleft cyst is difficult because of a complicated fistula tract. In addition to attempting chemocauterization with trichloroacetic acid (TCA) to avoid surgical complications, authors performed an electrocauterization to close internal opening of pyriform sinus. Materials and Methods : We reviewed ten patients of fourth branchial cleft cyst underwent TCA chemocauterization and electrocauterization simultaneously. Clinical characteristics including patient informations, medical records, treatment results were analyzed retrospectively. Results : Interval time until diagnosed with fourth branchial cleft cyst was variable from several days to decades. Five patients had a history of incision and drainage. Mean follow up period was 36.1 months and all patients were treated with no recurrence. Conclusion : TCA chemocauterization with electrocauterization can be a effective choice to reduce recurrence rate and ensure safety of patients of fourth branchial cleft cyst.

Objectives：The purpose of this study was to evaluate the variable sonographic features in addition to classic findings and to find the helpful characteristic findings for diagnosis of branchial cleft cysts. Subjects and Methods：We retrospectively analyzed the sonographic finding of 16 histopathologically proven branchial cleft cysts. Assessment involved the following variables : location related to carotid artery, size, cyst wall, border, margin, shape, internal echotexture, post echoic enhancement, orientation of longitudinal axis relative to the long axis of the neck, and tapering edge. Results：Most branchial cleft cysts were seen as well defined(15/16), oval shape(13/16), smooth inner (12/16) and outer margin(13/16), and post echoic enhancement(16/16). Their diameter varied from 1 to 6cm (mean 3.3cm). The branchial cleft cysts showed variable internal echopatterns；hyperechogenicity or pseudosolid appearance(1/16), heterogeneous echogenicity(4/16) in addition to classic form of anechoic(5/16) or hypoechoic internal echogenicity(6/16). Longitudinal axis of most branchial cleft cysts were arranged in the direction of the long axis of the neck(13/16) and some branchial cleft cysts had tapering edge(6/16). Conclusion：If both atypical sonographic findings and location are showed, longitudinal arrangement of long axis and tapering edge of branchial cleft cysts are helpful findings for differential diagnosis.

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.
