Occult papillary adenocarcinoma of the thyroid is known to be indolent, slow metastatic, and has a good prognosis. Occult thyroid carcinoma presenting as a blood-borne metastasis without obvious cervical lymph node involvement is extremely rare. A 65-year-old male patient was visited for hoarseness, dysphagia, and shortness of breath. Bronchoscopy with biopsy revealed a papillary carcinoma of thyroid by immunohistochemical staining. Head & neck CT revealed that involving both the upper esophagus and the posterior tracheal wall, extending into the mediastinum along the upper thoracic spine at $T_1-T_2$. We have experienced a rare case of occult papillary carcinoma which invaded the trachea, esophagus and fascia of thoracic spine. Treatment was initiated with radioactive iodine and external bean therapy.

Von Recklinghausen병에 동반되는 악성종양은 주로 신경섬유육종이지만 드물게는 폐암이 동반되는 경우가 보고되고 있고 ras 유전자가 양 질환의 발생에 영향이 있음이 알려져 있어 앞으로 이에 관한 연구가 필요하리라 생각된다.

Epithelial-myoepithelial carcinoma (EMC) of lung is a minor subset of salivary type carcinoma of lung of known low grade malignancy. Histologically, two-cell components forming duct-like structure with inner epithelial cell layer and outer myoepithelial cell layer are characteristics of EMC. In salivary gland, dedifferentiation of conventional low grade malignancy has been reported and is thought to be related with poor prognosis. However, precise histomorphology and prognostic factors of pulmonary EMC have not been clarified due to its rarity. Herein, we reported a rare case of EMC presented as endobronchial mass in a 53-year old woman, which showed predominant solid lobular growth pattern and lymph node metastases.

Pulmonary aspergillosis presents as the following three different types depending on the immune status of the host: invasive aspergillosis, allergic bronchopulmonary aspergillosis (ABPA), and aspergilloma. Aspergilloma develops as a result of an aspergillus growth inside a pre-existing lung cavity. However, endobronchial aspergilloma without a lung parenchymal lesion is quite rare. We encountered a case of endobronchial aspergilloma that developed in a healthy 75 year-old woman that led to necrotizing pneumonia of the right lower lobe. The chief complaints were fever, cough and yellowish sputum. The chest film revealed haziness with cavity-like shadows on the right lower lobe, and the chest CT scan showed endobronchial calcified density in the basal bronchus of the right lower lobe with peribronchial lymph node enlargement. Bronchoscopy revealed an obstruction of the basal orifice of the right lower lobe by blackish stone-like material, and the aspergilloma was confirmed by the bronchoscopic biopsy. The pneumonia improved after bronchoscopic removal of this lesion. We report this case along with a review of the relevant literature.

연구배경 : 종양 신생혈관은 종양조직에 산소 및 영양물질을 제공하고 종양조직에서 발생한 산과 독성 대시물질을 제거하여 종양의 성장을 가능하게 하며, 종양세포의 전신전이의 경로를 제공하는 역할을 하므로 종양의 혈관신생은 종양의 성장과 전이의 과정에서 필수적이다. 피부 악성흑색종이나 유암에서는 종양 혈관선생의 정도와 림프절 전이, 전선전이 및 예후와의 관련성이 잘 알려져 있다. 이에 본 연구에서는 비소세포성 폐암에서 종양 혈관신생 정도와 병기, 림프절 전이, 전선전이 및 예후와의 관련성에 대하여 알아보고자 하였으며 아울러 조직학적 유형간에 종양 혈관선생 정도의 차이가 있는 지에 대하여 알아보고자 하였다. 방 법 : 1989년 3월 1일부터 1998년 6월 30일까지 연세대학교 원주의과대학 원주기독병원에서 비소세포 폐암으로 진단 받은 후 완전 절제술을 실시하고 수술 전후에 보조요법을 시행하지 않았던 환자 45예를 대상으로 CD31 단세포 항체(JC70항체)를 이용하여 면역조직화학 염색을 실시하여 종양 혈관신생 정도를 파악한 후 종양 혈관선생 정도와 병기, 림프절 전이, 전신전이 및 예후를 비교 하였다. 결 과 : 비소세포 폐암의 조직학적 유형에 관계없이 IIIA, IIIB 병기의 환자에서 I, II 병기의 환자에 비하여 종양 신생혈관의 수는 의미 있게 증가되어 있었다(p<0.05). 선암종에서 림프절 전이가 있는 환자에서 림프절 전이가 없는 환자에 비하여 의미 있는 증가가 있었다(p<0.05). 선암종에서 편평상피세포 암종에 비하여 종양 신생혈관의 수는 의미 있게 증가되어 있었으며(p<0.05), I, II 병기와 N0병기에서는 선암종에서 편평상피세포 암종에 비하여 증가하는 경향을 보였으나 통계적 의미는 없었으며(p>0.05), IIIA, IIIB병기와 N1~3병기에서는 선암종이 편평상피세포 암종에 비하여 의미 있는 증가를 보였다(p<0.05). 조기전이가 일어난 환자(12개월 이내에 전선전이가 발견된 환자)에서 조기전이가 일어나지 않은 환자에 비하여 종양 신생혈관의 수는 의미 있게 증가되어 있었으며(p<0.05), 전체 대상의 종양 신생혈관 수의 중앙값(100배 시야 당 44개)을 기준으로 종양 신생혈관의 수가 많은 환자(>44개/100배 시야)는 적은 환자($\leq$44개/100배 시야)에 비하여 전신 전이율이 높았다(비교 위험도 10.83). 전체 대상환지에서 종양 신생혈관의 수가 많은 환자(>44개/100배 시야)는 적은 환자($\leq$44개/100배 시야)에 비하여 의미 있게 낮은 생존율을 보였다(p<0.05). 결 론 : 비소세포 폐암에서 종양 혈관신생은 병기, 림프절 전이(선암종에 한정되어), 조직학적 유형 및 조기전이와 관련성이 있으며, 종양신생혈관의 수가 증가할 수록 전신전이율이 높고 불량한 예후를 보임을 알 수 있었다. 이 결과로 비소세포 폐암에서 완전절제술 후 예후를 예측하고 전신적 보조요법을 시행할 환자를 선별하는데 있어서 종양 혈관신생 정도를 파악하는 것이 도움이 될 수 있을 것으로 생각된다.

저자들은 경부에 결핵성의 단일 한성농양을 보인 환자를 경험하였으며, 이 환자에서 결핵성 흉막염 치료시 소방형성으로 인해 흉수액의 배액이 안되었으나 도관을 통한 유로키나제의 주입으로 별다른 합병증없이 만족할만한 결과를 얻었기에 문헌고찰과 함께 보고하는 바이다.

Broncholithiasis is defined as a cor9ition in which a concretion is present within a bronchus or a cavity in the lung communicating with a bronchus. The usual causes of broncholithiasis are known as tuberculosis, histoplasmosis, silicosis, aspirated calculi, and a few fungal infections. It is generally accepted that the constant motion created by respiration and beating of the heart may cause the peribronchial calcified lymph node to erode into the tracheobronchial tree and to form broncholith. After the analysis of our 6 cases of broncholithiasis which were treated surgically in the Department of Thoracic Surgery, Seoul National University Hospital from 1960 to December, 1985, we could suggest that intrinsic formation of calculi should be regarded as the pathogenesis of broncholithiasis in addition to the extrinsic formation of calculi.

Fifty six consecutive cases of mediastinoscopy are analysed. The procedure was performed without any complication and mortality. It is concluded that the mediastinoscopy is a safe procedure and causes little disturbance to the patient. The value of mediastinoscopy as a diagnostic procedure for mediastinal and pulmonary hilar masses is shown. In my series, mediastinoscopy was performed in 17 cases, which could not be diagnosed by other means, for purpose of diagnostic procedure. A histologic diagnosis was obtained in 11 of the 17 patients [64.7%]. The findings are 6 cases of tuberculosis, 2 cases of metastatic carcinoma, 1 case of primary carcinoma, and one case of noncaseating granuloma. The histologic diagnosis of carcinoma in patients believed to have non-resectable tumors could be obtained in 4 of the 7 cases [57.1%]. Three cases out of 32 patients with presumably resectable bronchial carcinoma were found to have mediastinal lymph node metastases. Two patients of 29 cases refused to be operated on. The remaining 27 cases had thoracotomy and resection was undertaken in all but 9 cases [33.3%].

We reviewed 15 cases of mesothelioma of the pleura, of which three cases were localized benign form and 12 cases were malignant diffuse form. The tumors were distributed equally in both sexes, and occured most commonly in fifth to seventh decades. The history of exposure to asbestos was present in only one case. The chief complaints were mainly chest pain and dyspnea. Associated symptoms were cough, sputum, hemoptysis, weight loss, anorexia, chill. On physical examination, unilateral, decreased breathing sound was main feature. The simple chest radiograph showed masses in all localized mesotheliomas (100%) and in 2 diffuse mesotheliomas (17%). 8 cases of diffuse mesotheliomas (67%) showed unilateral pleural effusions. Pleural effusions were mainly bloody (67%), and almost all were exudates. In all localized mesotheliomas, final diagnosis was made by open thoracotomy. In diffuse mesotheliomas, final diagnosis was made by open thoracotomy in 7 cases, chest wall mass biopsy in 2 cases, thoracoscopic biopsy in 1 case, pleural biopsy in 1 case, and pleural biopsy combined with axillary lymph node biopsy in 1 case. Localized mesotheliomas were treated by simple excision with good prognosis. In diffuse mesotheliomas, surgical treatment (pleuropneumonectomy, pleurectomy), chemotherapy, or radiotherapy, alone or in combination, were used with dismal prognosis. The prognostic factors were not found due to the small number of cases, incomplete follow up, and early drop out.
