Branchio-otic syndrome(BOS) is a relatively uncommon genetic malformation associated with dysmorphogenesis of the first and second branchial arches and is characterized by branchial fistulae, congenital preauricular fistulae, and anomalies of the pinnae, external, middle, and inner ears, accompanied by hearing loss. Recently, we experienced a case of BOS in a 10 years old female patient and report this case with a review of literature. 10-year-old girl presented with hearing impairment, bilateral preauricular fistula and cervical fistula. The pure tone audiometry revealed that she had 60dB sensorineural hearing loss on right side and 90dB mixed hearing loss on left. Bilateral branchial fistula was found on the neck CT scan and bilateral ossicular and cochlear abnormality combined with enlarged internal auditory canal was noted on the temporal bone CT scan. To investigate the association with EYA1 gene, we performed DNA sequncing with peripheral white blood cell and found the point mutations on Exon 7, 12 and 16 of EYA1 gene. The preauricular fistula and branchial fistula was excised surgically and hearing aid was applied on her left side. There was no sign of fistula recurrence for seven years after the surgery.

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.

병변의 양상에 따른 감별진단 재발성 이하선 종대를 보이는 경우 타액선조영술이 영상진단방법중 1차적인 선택이 된다. Stensen 씨관이나 중심선관(central glandular duct)의 확장을 보이는 경우 만성 타액선염으로 진단할 수 있다. 소아에서의 단일성 양성종괴의 감별진단은 임파절, 혈관종, 양성혼합종양, 저급점액상피암, 임파관종 등이다. 성인에서의 단일성, 양성으로 관찰되는 종괴는 양성혼합종양, Warthin씨 종양, 저급점액상피암, 선상낭성암, 소포상세포암 등이다. 여러개의 종괴를 보이는 경우 Warthin씨 종양, 소포상세포암, 임파종, 육아종, 전이암 등이며 단일성 낭성종괴의 경우는 branchial cleft cyst,, Warthin씨 종양, 상피낭포 등이다.

Cystic metastasis in the neck from pharyngeal cancer has often been mistaken for either primary squamous cell carcinoma of branchiogenic origin or branchial cleft cyst. The distinctive histological and clinical features of cystic metastasis reviewed after its correct indentification can lead to the discovery of an unsuspected primary lesion and result in specific treatment options. Recendy, the authors experienced three cases of cystic metastasis in the neck from pharyngeal cancer ; one was from nasopharyngeal squamous cell carcinoma and the other two were from tonsillar squamous cell carcinomas. This report summarizes our experiences and review of the literatures.

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.

Carotid body paraganglioma is uncommon, with appoximately 900 reports of it in the world literature, and with only 7 documented cases in the Korean literature. The classic carotid body paraganglioma develops in the bifurcation of common carotid artery and involves both the internal and external carotid arteries at it expands. The diagnosis may almost always be established preoperatively by selective angiography which shows a widening of the carotid bifurcation with a well defined vascular mass. Differential consideration of a single, lateral cervical mass in this location include branchial cleft cyst, neurogenic tumor, metastatic thyroid cancer, carotid body aneurysm and salivary gland tumor. Surgical therapy is the preferred method of treatment as these tumors are regarded as radioresistant. Because of their high vascularity and anatomical location, surgical removal of these tumors reguires a considerable degree of caution and a high degree of surgical expertise. With improved diagnostic and surgical technique, the morbidity and mortality has been reduced lately. This report details the management of 3 patients with carotid body paraganglioma who underwent safe resection by subadventitial dissection or using an internal vascular shunt.

Neck masses can have various origins and diverse presentations, making accurate diagnosis challenging. Schwannomas and lymphoepithelial cysts are commonly encountered neck tumors, and it is hard to get differential diagnosis. A 50-year-old woman presented with a progressively enlarging right neck mass discovered five years ago. Upon examination, a 3 cm firm, non-tender, and mobile tumor was found in the right neck level II region. Imaging studies suggested a tumor originating from the cervical sympathetic chain. The patient underwent a resection of the tumor under general anesthesia. Postoperative follow-up showed no complications or signs of recurrence. However, contrary to the initial suspicion of a schwannoma, the final pathological examination revealed a lymphoepithelial cyst. In this paper, we present a case of a cervical lymphoepithelial cyst misdiagnosed as a schwannoma, aiming to compare the clinical and histological characteristics of these two tumors and provide insights into appropriate diagnosis and management.

1세된 남아에서 세열낭종을 의심한 좌측 경부 종양이 수술을 시행한 결과 고형종양이였고, 조직검사상 이소성 흉선으로 판명되었다. 술후 초음파상 흉선은 정상적으로 있었고, 현재 환자의 면역기능은 아무 이상없이 정상으로 자라고 있다.

Histologically proven 465 cases of neck mass in children were analized for the determination of the nature of lesions. Pathologic specimens were obtained during 10 years from January 1981 to December 1989 at Severance Hospital, Yonsei University, College of Medicine. 1) Congenital lesion was most common in neonate(80%) and congenital lesion and inflamatory disease were common in infancy and inflammatory disease was most common in more than one year old children. Thyroglossal duct cyst was most common(35.4%) disease of the congenital lesion. followed by cytic hygroma(34%) and branchial cleft remnants(29.2%). 2) Benign tumors were discovered most frequently in adolescence (55.2%) and thyroid adenoma(23.7%) and epithelial tumor(21.1%) and hemangiomas(19.7%) were most common. Most common malignant tumors were malignant lymphoma (50%) and Hodgkin's disease and were present in the older children. Metastatic cancers were very rare and their primary sites were deductable in all cases. 3) Reactive hyperplasia of lymph node was most common in inflammatory disease(23.7%). Tuberculosis lymphadenitis was more common than nonspecific lymphadenitis. 4) Bilaterality of lesion was commonly seen in malignant disease(41.7%), reactive hyperplasia of lymph node (38.85%) and metastatic disease(33.3%). Size and duration of the masses were not helpful in the differential diagnosis of the cause of the masses. Pediatric neck mass must be evaluated with its characteristics. sites, bilaterality, size and its cange, duration and patient's age but any of these alone cant not be predicted its causes without biopsy or excision. Biopsy or excision can be done with few complication but biopsy of lymph node for diagnosis is carefully made because a large number of lymph node biopsy showed no definite diagnosis in these selected cases of patients.
