선친성 경부 종양은 표재성, 무통성 종물로 임상적으로는 이차적 감염후 발견되는 경우가 많다. 이학적 검사 및 경부초음파 검사로 임상적 진단은 용이하나 확진을 위해서는 수술후 조직병리검사가 필수적이다. 저자들은 최근 2년간에 서울중앙병원에서 경부 종물을 주소로 내원하여 수술후 조직병리검사로 확진된 47례에 대해 후향적 조사를 실시하여 다음과 같은 결론을 얻었기에 문헌적 고찰과 함께 보고하는 바이다. 1)총 47례중 갑상설 낭종이 가장 많은 빈도를 차지하였고(31, 9%) 새성낭종(25.5%), 낭포성 히그로마(21.3%), 유표피낭포(14.9%), 혈관종(6.4% )순이었다. 2)성별 분포는 남녀간의 큰 차이 없었다. (남46.8%, 여 53.2%) 3)연령별 분포는 20대 이하에서 가장 많은 빈도를 보였다. (63.9%) 4)위치별 분포는 경부중앙(42.6%), 우측경부(38.3%), 좌측경부(19.1%)를 보였다. 5)주된 증상은 경부종물을 주소로 내원한 경우가 대부분이었으며, 증상의 기간은 1년 미만이(53.2%) 가장 많았다.

Ectopic cervical thymic tissue is rarely reported in medical literature, but it should be included in the differential diagnosis of neck masses, especially in children. It occurs in the line of descent of the thymus from the angle of the mandible to the superior mediastinum. A preoperative diagnosis is seldom considered and is often misdiagnosed as a possible tumor or a lymph node. We present a case of a 2-month-old infant with an asymptomatic enlarging right neck mass. Patient underwent complete excision of the mass.

Objectives : Patients with neck tumor and their family need every information about the disease. Especially, the size and location are confusing with verbal information. With the aid of CT, the problem had some answer, but it needs some medical education. We would like to know the usefullness of 3D reconstructed images in patient education about the disease. Material and Methods : Neck CT data were collected from 10 patients with various neck tumors and converted to 3D reconstructed images. Understanding of the patients about the size and location of tumors were rated from questionaires using axial CT images and 3D images. Results : Understanding score about 3D images were greater than that of CT images(p<0.006). Conclusion : 3D reconstructed images of CT could give the patients more real visual information about the disease.

Objectives : Getting full information from axial CT images needs experiences and knowledge. Sagittal and coronal images could give more information but we have to draw 3-dimensional images in mind with above informations. With aid of 3D reconstruction softwares, CT data are converted to visible 3D images. We tried to compare medical photographs of 15 surgical specimens from neck tumors with 3D reconstructed images of same patients. Material and Methods : Fifteen patients with neck tumors treated surgically were recruited. Medical photograph of the surgical specimens were collected for comparison. 3D reconstruction of neck CT from same patients with aid of 3D-doctor software gave 3D images of neck masses. Width and height of tumors of each photos and images from the same cases were calculated and compared statistically. Visual similarities were rated between photos and 3D images. Results : No statatistical difference were found in size between medical photos and 3D images. Visual similarity score were higher between 2 groups of images. Conclusion : 3D reconstructed images of neck mass looked alike the real photographs of excised neck mass with similar calculated sizes. It could give us reliable visual information about the mass.

Tuberculous cervical lymphadenitis is one of the most common causes of neck mass in Korea. But the diagnostic confirmation is difficult and it's effective treatment modalities are still in controversy. Through a retrospective study of 32 cases of tuberculous cervical lymphadenitis treated with surgical treatment during recent 4 years, we have analyzed 5 subtypes of CT finding and surgical treatment modalities and received following results 1. The locations of lymphadenitis were posterior triangle(12 cases), submandibular area(9 cases), supraclavicular area(8 cases), submental area(2 cases), and parotid area(1 case). 2. Five subtypes of CT findings were observed : Homogeneous enhancement type(3 cases), peripheral rim enhancement type(6 cases), peripheral rim enhancement with perinodal fat obliteration type(12 cases), coalescent cold abscess type(8 cases), and mixed type(3 cases). 3. Surgical treatment modalities : Excision (13 cases), incision and drainage(9 cases), selective neck dissection(8 cases), and curettage(2 cases).

Phlebectasia is an abnormal dilatation of an isolated vein and a rare venous anomaly and is usually asymptomatic. Clinically internal jugular phlebectasia is a self limited benign condition and usually no treatment is required after initial diagnosis. So suspection of this disease and appropriate diagnostic approaches are essential to avoid unnecessary surgical intervention. We present three cases of internal jugular phlebectasia of which diagnosis was made by neck sonography and CT.

Kimura's disease is a chronic inflammatory disorder of unknown etiology. A 14 year old boy suffering from steroid dependant nephrotic syndrome, was presented with relapsing painless subcutaneous masses on the left buccal area. Blood analysis showed increased IgE and eosinophilia. During 4 years follow up, he was been treated by low dose steroid and short term cyclosporine. Consequently, frequent relapses of subcutaneous masses and nephrotic syndrome has been relieved. Cyclosporine treatment combined with steroid may be useful for preventing frequent relapse of Kimura's disease.

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.
