This report presents a unique case of an endocervical polyp-mimicking malignancy on pelvic MRI in a 45-year-old female. The MRI depicted a multilocular cystic lesion with an enhancing solid component, raising suspicion for malignancy. However, histopathological examination definitively revealed a benign endocervical polyp. This case highlights the limitations of diagnosing cervical lesions solely on MRI features, emphasizing the potential for benign conditions to mimic malignancy.

Purpose : It is well known that the risk of lymph nodes metastases to head and neck cancers are influenced by the location and size of the Primary tumor. as well as the degree and types of histological differentiation. However, data on the statistical analyses of lymph node metastases from the head and neck cancers among Korean Population are not available at present. In order to obtain current status of such data, we have analyzed cancer patients at the department of radiation oncology, korea universityhospital for radiation treatment. Materials and Methods : We have evaluated nine-hundred and ninetyseven (997) head and neck cancer Patients who visited to the Department of radiation oncology, between November 1981 to December 1995. After careful physical examinations and CAT scan, Patients were divided into two groups, those with positive lymph node metastases and with negative lymph node metastases. The nodal status were classified according to the TNM system of American Joint Committee on Cancer (AJCC) Besults : Four-hundred and sixteen Patients out of the 997 patients were lymph node positive $(42\%)$ and 581 patients were lymph node negative $(58\%)$ when they were first presented at the department of radiation oncelogy. According to the AJCC classification, the distribution of positive lymph node is as follow: Nl:106 $(25.5\%),\;N2a:100\;(24\%),\;N2b:68\;(16.4\%),\;N2c:69\;(16.6\%),\;3:73\;(15\%).$ respectively. The frequency of lymph node metastases according to the primary sites is as follow : larynx 283 $(28.5\%)$, paranasal sinuses: 182 $(18\%),\;oropharynx:144\;(14.5\%)\;nasopharynx:122(12\%),\;oral\;cavity\;92\;(9\%),\;hypopharynx:71\;(7\%),\;falivary\;gland:58\;(6\%)$ unknown primary:31 $(3\%),\;skin:\;14(2\%)$,. The most frequent Primary site for the positive Iymph node metastases was nasopharynx $(71\%)$ followed by hypopharynx $(69\%),\;oropharynx\;(64\%),\;oral\;cavity\;(39\%)$ The most common histologic type was squamous cell carcinoma (652/997: $65.4\%$). followed by malignant lymphoma $(109/997:11\%)$. Conclusion : Statistical results of lymph node metastases from head and neck cancer at our department were very similar to those obtained from other countries. It is concluded that the location of Primary cancer influences sites of metastases on head and neck, and stage of the primary cancer also influences the development of metastatic lesions. Since the present study is limited on the data collected from one institute. further statistical analyses on Korean cancer Patients are warrented.

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.

Descending necrotizing mediastinitis(DNM) is a rare complication of the oropharyngeal and cervical infection. Descending necrotizing mediastinitis requires an early and aggressive surgical approach to reduce the high morbidity and mortality associated with this disease. A 39-year-old man complained of odynophagia, neck swelling, and disturbance of swallowing with dyspnea. CT scans of the neck suggested a peritonsillar abscess and retropharyngeal and peripharyngeal abscess. He underwent cervical drainage. He remained febrile and complained of severe both pain in both shoulders. On postoperative day 5, a follow-up CT scan confirmed a mediastinal abscess. Reexploration of the neck and right thoracotomy for debridement and drainage of the mediastinal abscess were performed.. A large amount of pus was drained from the anterior and posterior mediastinum and its necrotic tissue was debrided. The patient's condition and radiologic findings gradually improved. Cultures of the drain fluid revealed Klebsiella pneumoniae. He was discharged on the 85th hospital day. In our experience, both transcervical drainage and aggressive mediastinal exploration via thoracotomy can lead to an improvement in the survival of the patient with descending necrotizing mediastinitis. CT scanning is useful for early diagnosis of mediastinitis and for follow up.

인체에서 발견되는 전체 신경초종중 $25{\sim}40%$가 두경부에서 발견되나 경부미주신경의 신경초종은 매우 희귀하여 1988년까지 영문문헌상 88 예가 보고되어 있다. 임상적으로 경부종괴가 주증상이며 때로는 애성, 종괴촉지시 기침 혹은 방사통, parapharyngeal space 의 종괴성장으로 연하곤란등이 초래되기도 한다. 치료는 종괴의 완전적출과 미주신경의 기능을 보존시키는 것이 주요 목표로 되어 있다. 저자들은 최근 5년간 4 예의 정부미주신경외 신경초종을 경험하였는데, 3 예는 측경부의 상부에, 1예는 측경부의 하부에 발생한 것이었다. 연령은 25세에서 50세까지 성인연령이었고, 성별은 남자 l 예, 여자 3 예이었다. 내원시 주소는 전예가 무통성 경부종괴이었으며, 종괴의 크기는 직경 3cm에서 10cm까지 다양하였다. 전예에서 종괴로 인한 신경학적 증상은 없었으나, 1 예에서 parapharyngeal space 의 거대종괴 때문에 다소간의 연하곤란이 있었다. 2 에에서는 종괴촉지시 기침이 유발됨을 호소하였다. 수술은 경부횡절개로 흉쇄유돌근을 제치고 총경 동맥과 내경정맥을 종괴의 상하부위가 완전히 노출되도록 박리한 후 종괴의 피막을 미주 신경의 주행방향에 따라 절개하여 적출 (enucleation) 하였다. 적출술시 종괴가 유착되어 있는 피막 부위는 동시에 절제하되 미주신경의 신경경로 (neural pathway) 는 유지되도록 하였다. 수술직후 2 예에서 일시적 애성을 호소하였다, 추적은 최단 20 개월에서 최장 80 개월까지 하였는데 일시적 애성은 호전되었고 전예가 재발없이 건강하게 지내고 있었다. 따라서 본 종양수술은 종양적출술시 이환된 미주신경의 절단을 결정하기 전에 신경경로를 유지시킬 수 있는 적출술 (enucleation) 을 먼저 고려하는 것이 바람직하다고 사료되었다.

This is a report of three cancer patients treated with the different methods of neck dissection considering the state of the each patient. 1. A 76-year old femals patient who showed $T2_N0_M0$ squamous cell carcinoma received the regional neck dissection with resection of primary lesion. The postoperative result was uneventful without recurrence for 3.6 years. 2. A 52-year old male patient who was diagosed $_T3_N1_M0$ squamous cell carcinoma was treated with the bilateral neck dissection and radical resection of primary lesion. Metastasis was noticed on the right scapular area 8 months postoperatively. We treated him with radiation and chemotherapy, but he died 13 months postoperatively. 3. A 55-year old male patient who showed $_T2_N1_M0$ squamous cell cvarcinoma was treated with the classical neck dissection and the radical resection of primary lesion. The postoperative result was good with no recurrence for 4 years.

Purpose: The authors measured the anteversion of the femoral neck and acetabulum and the sum of the two values in normal Korean people by computed tomography. The authors examined the normal range of the values to analyze the difference in sex and sides as well as the relationship between the femoral neck and acetabular anteversion. Materials and Methods: The authors measured the anteversion of the femoral neck and acetabulum in 118 normal Korean adult males and 114 females aged between 21 and 49 on both the right and left sides by computed tomography and calculated the sum of anteversion. The authors analyzed the mean and standard deviation, and investigated the sex differences and side differences, as well as the relationship between the acetabular anteversion and femoral neck anteversion statistically. Results: The anteversion of the acetabulum in males was 15.3°±6.1° on the right side and 15.3°±6.6° on the left side. The anteversion of the femoral neck in males was 5.3°±7.6° on the right side and 1.5°±9.2° on the left side according to the Hernandez et al. method. The anteversion of acetabulum in females was 16.8°±5.4° on the right side and 16.3°±5.8° on the left side. The anteversion of femoral neck in females was 10.3°±8.2° on the right side and 7.9°±8.2° on the left side according to Hernandez et al. method. No difference in acetabular anteversion, and a significant difference in the femoral neck anteversion on both the right and left sides were observed between males and females. No difference of acetabular anteversion was observed between the right and left sides, but a significant difference in femoral neck anteversion was noted between the right and left sides measured by either the Hernandez et al. method or Weiner et al. method. The Pearson coefficient revealed no correlation between the femoral neck anteversion and acetabular anteversion. Conclusion: No difference in the acetabular anteversion was observed, but there was a significant difference in femoral neck anteversion between males and females. A significant difference in femoral neck anteversion was observed between the right and left sides. No correlation was noted between the anteversion of the femoral neck and acetabulum.
