저자들은 흉부식도암의 근치적 절제후 국소재발을 보인 1례를 치험하였기에 보고하는 바이다. 환자는 식도아절제술후 후종격동 경로를 통한 경부식도-위 문합술을 시행받았었다. 수술 20개월후 환자는 연하곤란을 주소로 내원하였고 컴퓨터 단층촬영과 경피적 세침흡인 조직검사등을 통해 국소재발을 확인하였다. 환자는 경부식도절제, 위 분문부의 부분절제 및 후두절제를 시행하고 유리공장 이식 편을 이용하여 재건술을 시행하였다.

골수외 형질세포종은 아주 드물게 발생하는 종양으로, 전체 형질 세포 종양의 3~5 %를 차지하며 상부 호흡기관에서 주로 발생한다. 그 외 드물게 위장관, 방광, 중추 신경계, 유방, 갑상선, 고환, 타액선, 임파선, 피부 등에서 발생한 증례보고가 있다. 저자들은 49세 남자의 대둔근에서 발생한 골수외 형질세포종 1예를 경험하였기에 이를 문헌 고찰과 함께 보고하는 바이다.

목적 이 연구는 갑상선 미세유두암을 고주파 절제술로 치료한 후 10년 이상 경과 관찰한 환자들의 결과를 통해 효과와 안전성을 평가하고자 했다. 대상과 방법 2006년 11월부터 2009년 12월까지 갑상선 미세유두암을 고주파 절제술로 치료받은 환자 5명을 대상으로 하였다. 이 환자들은 모두 조직검사를 통해 갑상선 미세유두암으로 진단을 받았고, 병변은 갑상선 내에 국한되어 있었으며, 전이의 증거가 없었고, 수술이나 전신마취가 의학적으로 부적합하거나 수술을 거부한 환자들이었다. 고주파 절제술은 고주파 발생기와 냉각기를 사용하여 한 명의 영상의학과 의사가 시행하였다. 우리는 시술과 연관된 부작용, 소작된 종양의 변화, 재발 여부, 국소 또는 림프절 전이 등에 대해 초음파 영상 소견과 의무 기록을 토대로 분석하였다. 결과 평균 경과 관찰기간은 130.6개월(범위, 121~159개월) 이었다. 세 명의 환자는 한 번의 고주파 절제술을, 두 명의 환자는 두 번의 시술을 받았다. 다섯 명의 환자 모두 시술과 연관된 부작용은 보이지 않았다. 다섯 개 중 세 개의 종양은 시술 후 완전히 사라졌으며 두 개의 종양은 최소한의 흔적으로 남아 평균 16.8개월의 경과 관찰기간 동안 큰 변화가 없었다. 가장 최근의 경과관찰에서 다섯 명의 환자 모두 국소 전이나 림프절 전이는 보이지 않았고 갑상선 글로불린(thyroglobulin)의 수치도 정상 범위였다. 결론 고주파 절제술은 수술에 부적합하거나 수술을 거부하는 저위험 갑상선 미세유두암 환자들에 대해서 효과적이고 안전한 치료법이 될 수 있다.

Wide vertical hemilaryngopharyngectomy with immediate glottic and pharyngeal reconstruction using a radial forearm free flap is reported in 1991 by Chantrain et al. This procedure was designed for the preservation of healthy hemilarynx and resection of pharynx with safe oncological margin in especially piriform sinus cancer or supraglottic cancer invading the hypopharynx. In the original paper, they used palmaris longus tendon for reconstruction of neoglottis. In other groups, they used rib cartilage instead of palmaris longus tendon. In this paper, we report two cases of piriform sinus cancer patients who treated with wide vertical hemilaryngectomy with radial forearm free flap reconstruction. In one case, the operation was performed as Chantrain et al described. But in another case, the ipsilateral forearm was impossible due to the positive Allen's test. So the contralateral forearm flap and rib cartilage graft was done. This reconstructive technique make large resection possible. As the dissection of thyroid cartilage and lateral displacement makes direct visualization and manipulation of piriform sinus lesions, sufficient resection margin in lateral and inferior pharyngeal wall cab be obtained.

Reconstruction of the pharynx and cervical esophagus presents a tremendous challenges to surgeons. Over the past 2 years[1990, Dec.-1993, Jun], the free jejunal graft has been performed in 17 cases in Korea Cancer Center Hospital.The indications of this procedures were almost malignant neoplasms involving neck and upper aero-digestive tract; Hypopharyngeal cancer[12 cases, including 2 recurrent cases], laryngeal cancer[2 cases], thyroid cancer[2 cases, including 1 recurrent case], cervical esophageal cancer[1 case]. There were fifteen men and two women, and the mean age was 59.6 years. The anastomosis site of jejunal artery were common carotid artery[16 cases] or external carotid artery[1 case] and that of jejunal vein were internal jegular [15 cases] or facial[1 case] and superior thyroid vein[1 case]. The length of jejunal graft was from 9 cm to 17 cm[mean 13 cm] and the mean ischemic time was 68 minutes. There was one hospital mortality which was irrelevant to procedures[variceal bleeding] and one graft failure[1/16]. Other postoperative complications were neck bleeding or hematoma[3 cases], abdominal wound infection or disruption[5 cases], anastomosis site leakage[1 case], pneumonia[2 cases], graft vein thrombosis[1 case], and food aspiration[1 case]. The function of conduit was excellent and ingestion of food was possible in nearly all cases. Postoperative adjuvant radiation therapy was also applicable without problem in 7 cases. During follow-up periods, the anastomosis site stenosis developed in four patients, and the tracheal stoma was narrowed in one case but easily overcome with dilation. In conclusion, we think that the free jejunal graft is one of the excellent reconstruction methods of upper digestive tract, especially after radical resection of malignant neoplasm in neck with a high success rate and low mortality and morbidity rate.

Background: The phenomenon of occult carcinoma maybe observed in patients with clinically unilateral papillary thyroid microcarcinoma (PTMC). Although many studies have reported that the $BRAF^{T1799A}$ mutation is associated with aggressive PTMC, the relationship between $BRAF^{T1799A}$ mutation and occult carcinoma is unclear. The aim of this study was to investigate the risk factors, including $BRAF^{T1799A}$ mutation, for occult contralateral carcinoma in clinically unilateral PTMC accompanied by benign nodules in the contralateral lobe. Materials and Methods: From January 2011 to December 2013, we prospectively enrolled 89 consecutive PTMC patients with clinically unilateral carcinoma accompanied by benign nodules in the contralateral lobe who received a total thyroidectomy and cervical lymph node dissection. $BRAF^{T1799A}$ mutation was tested by pyrosequencing on postoperative paraffin specimens. The frequency and predictive factors for occult contralateral carcinoma were analyzed with respect to the following variables: age, gender, family history, tumor size, presence of Hashimoto thyroiditis, extrathyroidal extension, central lymph node metastasis, multifocality of primary tumor, or $BRAF^{T1799A}$ mutation. Results: A total of 36 patients (40.4%) had occult PTMC in the contralateral lobe. The median diameter of the occult tumors was $0.33{\pm}0.21cm$. The $BRAF^{T1799A}$ mutation was found in 38 cases (42.7%). According to the univariate analysis, there were no significant differences between the presence of occult contralateral carcinoma and age, gender, family history, tumor size, presence of Hashimoto thyroiditis, extrathyroidal extension, central lymph node metastasis, multifocality of primary tumor, or $BRAF^{T1799A}$ mutation. Conclusions: Using current methods, it is difficult to preoperatively identify patients with PTMC, and further research is needed to determine predictive factors for the presence of occult contralateral carcinoma in patients with unilateral PTMC.

Oral metastatic tumors are uncommon and account for about 1% of malignant oral neoplasm. The metastatic lesions are common in breast, lung, kidney and thyroid cancer. About 20% of oral mucosal metastasis is founded before detection of primary lesions. Usually, the metastatic lesions of the oral cavity are involved in the jaw bone, especially mandible more than the oral soft tissues. We report a case diagnosed as the stomach cancer with mandible metastatic lesion looking like TMJ abscess.

The authors observed the clinical status of 29 patients with vocal cord paralysis caused by tumor from April, 1983 to September, 1993 at Department of Otorhinolaryngology, Yongdong Severance hospital, Yonsei University College of Medicine. The results were as follows: 1) In the kinds of neoplasms, the most frequent were lung Ca. with 13 cases(44.8%), followed by 8 cases by thyroid Ca., 3 cases by neurogenic tumor, 2 cases by mediastinum tumor, cervical esophagus Ca., tracheal Ca., glomus jugulare were 1 case each. 2) In sex distribution, there were 18 cases of males and 11 cases of females with the male to female ratio being 1.8:1. In age distribution, most of the cases(10 cases ; 34.5%) were in the 7th decade. 3) In chief complaints, most of the cases(17 cases : 58.6%) had hoarseness only and aspiration, stridor, dyspnea, cough, dysphagia were present in some cases. 4) In site of the paralysed vocal cord, 21 cases were in the left cord. 5 cases in the right cord and 3 cases in the both cords. 5) In the position of paralysed vocal cord, most of the cases(23 cases : 79.3%) were in the parmedian position.

An endobronchial metastasis is defined as a subsegmental or a more proximal central bronchial metastasis of a nonpulmonary neoplasm in the bronchoscopically visible range. However, the frequencies of endobronchial metastasis range from 2 to 50% of pulmonary metastases from extrathoracic neoplasms by a different definition of an endobronchial metastasis. Primary neoplasms of an endobronchial metastasis including breast cancer, colon cancer, renal cell carcinoma, and ovarian cancer are relatively common. However, an endobronchial metastasis arising from thyroid cancer, parotid gland tumor, bone tumor, bladder cancer, and stomach cancer has only rarely been reported in the literature. Here we report a case of an endobrochial metastases from a hepatocellular carcinoma.

Tc-99m-MIBI는 비특이적 반응으로 양성 비종양성 질환의 일종인 활동성 폐결핵에 섭취가 증가되며, 이의 치료 후 추적 관찰에도 유용할 것으로 생각된다. 특히 만성 폐결핵 환자에 있어 방사선학적으로나 객담검사는 음성이었으나 재발이 의심될 때, tuberculin skin test 상 양성이나 단순 흉부 검사상 확실치 않을 때 유용하게 이용되리라 사료된다.
