Adenoid cystic carcinoma(ACC) is one of the common malignant tumor of the major and minor salivary glands. ACC arising from the larynx is relatively rare(less than 1% of laryngeal malignant tumors) and only about eighty cases have been reported in the English literature. Definite diagnosis of these lesions is made only from a histological analysis, because findings and symptoms are non-specific. The diagnosis progresses very slowly, therefore it often presents at an advanced stage with regional and distant metastasis. Here, we present one case of ACC of the supraglottic region with a review of literature.

Lobular capillary hemangioma (LCH) is a type of benign vascular tumor. It arises from vascular endothelial cells and contains capillaries arranged in a lobular pattern. In the head and neck, the most common presenting location of LCH is the lips, and presentation in the larynx is very rare. LCH might not be distinct from granuloma in macroscopic views. We report a 71-year-old female with LCH of the larynx that was totally resected via laryngeal microsurgery with a CO₂ laser and briefly review the literature.

Minimally invasive strategies are increasingly popular in patients with myasthenia gravis (MG)-associated thymomas. Within the context of video-assisted thoracoscopic surgery (VATS) as a widely known minimally invasive option, the most recent achievement is uniportal subxiphoid VATS. In MG patients, it is mandatory (1) to minimize perioperative interference with administered anesthetics to avoid complications and (2) to achieve a complete surgical resection, as the prognosis essentially depends on radical tumor resection. In order to fulfill these criteria, we merged this surgical technique with its anesthesiologic counterpart: regional anesthesia with the maintenance of spontaneous ventilation via a laryngeal mask. Non-intubated uniportal subxiphoid VATS for extended thymectomy allowed radical thymectomy in all MG patients with both rapid symptom control and fast recovery.

다발성 원발성 악성종양은 최근 발생 빈도가 증가하고 있으며 이는 암의 진단 방법의 개선 및 인구의 고령화, 유해물질에 대한 노출증가에 기인한다. 국내에서도 다발성 원발성 악성종양에 대한 연구가 진행되어왔으며, 김등, 윤등이 보고하였다. 그러나 삼중복암의 발생하는 빈도는 매우 낮은 것으로 보고되어있다. 저자들은 이화여대 동대문 병원 내과에 입원한 다발성 원발성 위암, 후두암, 폐암 환자의 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

Background and Objective : Papillary thyroid microcarcinoma(PTMC) is known as slow growing cancer with good prognosis. However, extrathyroidal extension may increase the risk of cervical lymph node metastasis and local invasion to surrounding structures. The aim of this study was to assess the characteristic features of the tumor invading the posterior thyroid capsule. Material and Methods : We made a retrospective review of 123 PTMC patients with thyroid capsule invasion, pathologically staged as T3 or T4. 74 patients (60.2%) had invasion to posterior thyroid capsule (group A) while 49 patients (39.8%) had invasion to-anterior thyroid capsule or anterior wall of trachea (group B). We assessed the clinicopathologic factors of the patients according to the location of capsular invasion of PTMC. Results : There was no difference regarding age, gender, T and N classification and incidence of lymph node metastasis between two groups. Local invasion rate to recurrent laryngeal nerve was 6.8% in patients with posterior thyroid capsule invasion, while the incidence was zero in those with capsular invasion to other locations Conclusion : Increased risk of local invasion to the recurrent laryngeal nerve should be considered in patients with PTMC presenting invasion of the posterior capsule.

Background. Lymphoma of the vocal fold is extremely rare due to low lymphoid content in the larynx. To date, fewer than 100 cases of laryngeal lymphoma have been reported; however, none of these literatures are concerned about exclusive laryngeal involvement of recurred lymphoma which initially appeared in other body sites. Specific consensus about management for these patients yet to exist, due to its rare occurrence; however, the main modality of treatment is chemotherapy alone or in combination with radiation therapy. Case. Herein, we report a case of a 51-year-old female patient who had recurrent T-cell lymphoma developing in bilateral vocal folds. The patient was originally diagnosed of T-cell lymphoma in right colic flexure 10 years ago, and was cured by chemotherapy. Immunohistochemical stain revealed the histologic type of recurred tumor in the vocal folds that are identical to the previously cured lymphoma. Conclusion. To the best of our knowledge, this was the first case that recurrent lymphoma occurred solely in the vocal folds. Despite its rarity, lymphoma should be put in the index of suspicion among those patients with decreased vocal fold mucosal wave without definite vocal fold mass who had a history of cured lymphoma.

이비인후과 영역에서 유표피낭종이 구강내에서 흔히 발생하지는 않으나 만약 존재한다면 보통 하악과 설골사이에 위치한다. 더구나 후두개에 발생한 유표피낭종은 드물게 보는 것으로서 최근 저자들은 후두개의 후두면에 발생한 유표피낭종 1례를 경험하고 경설골 인두절개술을 이용하여 종물에 접근하여 조대술을 시행한 후 성공적으로 치료된 1례를 보고하는 바이다. 환자는 46세된 남자로서 입원 이년전부터 간헐적인 인두통, 8개월부터 사성 및 1개월여의 호흡곤란을 주소로 내원하였다. 간접 후두경 검사로 후두개의 우측 후두면에 둥글고 표면이 매끄러우며 탄력성이 있고 그 크기가 구난 크기인 종물을 발견 할 수 있었다. 생검조직검사 결과 상피세포성 폴립으로 판명되어 입원하고 경설골 인두절개술을 이용하여 낭종의 조대술을 실시하였다. 술후 조직검사 결과 유표피낭종으로 판명되었고 경과가 양호하여 아무런 후유증 또는 합병증이 없이 퇴원하였기에 보고한다.

When thyroid carcinoma invades the larynx or trachea, the proper treatment is needed because of significant morbidity and mortality due to airway obstruction. Hemoptysis and dyspnea are the result of intraluminal extension of the tumor and call for immediate investigation with endoscopic examination and CT. If the thyroid carcinoma with extracapsular spread invades only outer perichondrium of the tracheal or laryngeal cartilage, the shaving operation would be sufficient, but if the tumor invades the cartilage or if there is intraluminal invasion, it is mandatory to remove partial or total part of some aerodigestive tract structures. We retrospectively analyzed 14 surgical cases of the thyroid cancer with laryngotracheal invasion(12 papillary carcinomas and 2 anaplastic carcinomas) at the Department of Otorhinolaryngology-Head and Neck Surgery, Seoul National University Hospital. The analysis was focused on clinical manifestation, pathologic findings, types of management and results. Survival result was not adequately analyzed due to some recently operated cases.

The clinical staging systems for oral squamous cell carcinoma is limited as a prognostic indicatior because of different biological characteristics of cancer in this region and variable microenvironment depending on subsites, there have been study to determine prognosis by evaluating malignancy, that is the nature of tumor cells. Many studies have been tried to determine prognostic indicator in various malignancies for the evaluation of differentiation capacity and the expression of oncogene product. EGF make a role in cellular growth and differentiation and to be essential in cellular survival. EGFR is an intergral membrane protein, stimulate cellular differentiation and hormonal secretion, and has structural homology with V-erb-B transforming protein. Recent reports have demonstrated that EGFR is overexpressed in stomach, breast, vagina, dermis, head and neck, genitourinary and lung tumors, and possibly used as a tumor marker. In head and neck region, most of studies were mainly carried out on laryngeal squamous cell carcinoma. In the present study, immunohistochemical study for EGFR and C-erb-B2 gene in paraffin sections of 45 squamous cell carcinoma in oral cavity was performed to evaluate the presense of EGFR and C- erb-B2 gene in this lesion, to evaluate them as a prognostic indicator by analysing the correlation between these expression and subsites, primary stages, clinical stages, pathologic grades, neck node metastasis, recurrences and treatment results, and to determine relation between EGFR and C-erb-B2 gene.
