A sleeve lobectomy is an appropriate operative procedure in patients with endobronchial neoplasms of low-grade malignancies in the proximal airways and for a small but significant number of patients with carcinoma. Here, we present eleven cases of sleeve lobectomy which were performed from 1984 to the August of 1991 in the Department of Thoracic Surgery of Seoul National University Hospital. The sex distribution was 6 males and 5 females in the age range from twenty to sixty seven, with an average of 44.9 years. The pathologic diagnoses were 7 cases of pulmonary malignancies: carcinoid in two, mucoepidermoid carcinoma in two, adenoid cystic carcinoma in one, adenocarcinoma in one, and squamous carcinoma in one. Other diagnoses were two cases of tuberculous bronchial strictures and two cases of benign tumors: one case of pesudolymphoma and one case of neurilemmoma. The procedures consisted of five right upper sleeve lobectomies [Fig. 1], four left upper sleeve lovectomies [Fig. 2], one left lower sleeve lobectomy[Fig. 3], and one right middle and lower lobetomy [Fig. 4]. All except one had a normal preoperative pulmonary function. The case which had a poor pulmonary function was a 66-year-old female adenocarcinoma patient. She seemed to be very intolerable to pneumonectomy [predicted FEV1=0.60L]. Therefore, she had a right sleeve upper lobectomy and experienced smooth postoperative course without any pulmonary problems. All cases had good postoperative results and no postoperative complications.

Primary pulmonary lymphoepithelioma-like carcinoma (LELC) is rare, with a more favorable prognosis compared with that of other types of non-small cell lung cancers. Herein, we describe an interesting case of primary pulmonary LELC confirmed postoperatively, which had been initially diagnosed as poorly differentiated adenocarcinoma. We suggest that despite the rarity of pulmonary LELC, it should be included as one of the differential diagnoses for lung malignancies. Physicians should consider taking a larger biopsy, especially when histologic examination shows undifferentiated nature.

Mucoepidermoid carcinoma of lung are rare carcinoma arising from the submucosal glands tissue of the proximal tracheobronchial tree. The carcinoma can be divided into low grade and high grade varienties. The most important factors in the prognosis include histological grading and the ability to achieve a complete surgical resection. We experienced a case of high grade mucoepidermoid carcinoma in pulmonary tuberculosis patient of 67 years old male who has been suffered from left chest pain for several weeks. He was not treated and died seventeen months later.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a useful, safe diagnostic modality for evaluating mediastinal and hilar lymphadenopathy. We report a 51-year-old male who presented with a left renal mass and multiple pleural masses without lung parenchymal lesions. The pleural masses were thought to be metastatic tumors or malignant mesothelioma. The patient underwent two percutaneous needle biopsies of the pleural mass, but the specimens were insufficient for a histopathological diagnosis. Because one pleural mass was adjacent to the right main bronchus, we decided to perform EBUS-TBNA for the pleural mass. As a result, sufficient core tissue was obtained with no complications, and the histopathological findings were consistent with metastatic papillary renal cell carcinoma. To our knowledge, this is the first case of using EBUS-TBNA for a pleural mass.

We report here an unusual case of pericardial tuberculoma that was misdiagnosed as thymic carcinoma on an imaging study. A 48-year-old woman was referred for evaluation of an anterior mediastinal mass. Computed tomography (CT) scans of the chest displayed cystic masses mimicking thymic carcinoma at the anterior mediastinum. Pericardiotomy and surgical drainage of the cystic masses were done, and pathologic examination of the excised pericardial specimen showed a chronic granulomatous inflammation with necrosis, compatible with tuberculosis. Acid-fast bacilli were also identified in the specimen. After treatment with anti-tuberculosis drugs and steroids, the patient showed clinical improvement. Although tuberculous pericarditis usually presents as pericardial effusion or constrictive pericarditis, it can also present as a pericardial mass mimicking thymic carcinoma on CT. Therefore, we suggest that tuberculous pericardial abscess should be included in the differential diagnosis of a mediastinal mass in Korea, with intermediate tuberculosis prevalence.

Background: During the follow up period after transarterial embolization(TAE), cases of pulmonary metastasis were more prevalent in TAE-treated patients than in TAE-untreated patients. Therefore, a study was conducted to evaluate whether TAE increases the incidence of pulmonary metastasis of hepatocellular carcinoma and to clarify the risk factors for pulmonary metastasis. Methods: From March 1991 to March 1995, 156 patients who had been diagnosed with hepatocellular carcinoma by serology, and radiographic and histologic methods at Yeungnam University hospital were involved in this study. We excluded 12 patients with lung metastasis on initial diagnosis and the others. The remaining 144 patients had been followed up for at least 5 months and, divided into four groups according to lung metastasis and trans-arterial embolization treatment, and evaluated for age, sex, child-pugh score, liver cirrhosis, and level of AFP. Results: Pulmonary metastasis was found in 18.0% (26/144), of which 92.3%(24/26) and 7.7%(2/26) of the patients with and without transarterial chemoembolization, respectively. Of the patients, 23.5% (24/102) with TAE had lung metastais during follow-up periods and 4.7% (2/42) without TAE had lung metastasis. There was more likelihood for lung metastasis after TAE. but there was no difference between two groups in age, sex, child-pugh class, the presence of liver cirrhosis, and AFP. Conclusions: The incidence of pulmonary metastasis of hepatocellular carcinoma after TAE was higher. Child-pugh class was the only related clinical preciptating factors for pulmonary metastasis in TAE in our study. Our results suggest that regular chest X-ray check-ups may be more frequently needed by patients who had TAE treatment for hepatocellular carcinoma.

Urothelial carcinomas (UCs) can occur in the upper urinary tract or lower urinary tract. Upper urinary tract urothelial carcinoma (UUT-UC) is relatively a rare disease and accounts for only about 5% of UC cases. Sporadic cases of late-onset metastasis, associated with UC of the bladder, have occasionally been reported. In contrast, no late-onset distant metastatic UUT-UC without local recurrence has, to the best of our knowledge, been reported in the English literature. We report an extremely rare case of distant metastatic UC, mimicking lung adenocarcinoma that originated from UUT-UC 12 years previously.

Pulmonary lipiodol embolism is a rare but very fatal complication of transcatheter arterial chemoembolization (TACE), Here we present the case of an unusual complication of TACE in a 67-year-old man who presented with dyspnea, hemoptysis, and a history of a third session of TACE for hepatocellular carcinoma (HCC) that had been performed 3 days prior to presenting. On the basis of chest X-ray and computed tomography (CT) scan findings, we diagnosed pulmonary lipiodol embolism. He was conservatively treated with oxygen and haemostatic agents. The patient recovered quickly without any significant sequela and was discharged.

Small cell carcinoma is a highly malignant esophageal tumor composed of anaplastic small cells with features very similar to those of its pulmonary counterpart. The prognosis is poorer than that of squamous carcinoma of the esophagus because of its propensity of generalized spread and metastasis. Once the diagnosis of small cell carcinoma was established, surgery should be undertaken as early as possible. We have described an experience of small cell carcinoma of the lower esophagus in a 72 year old male patient with a review of the literatures regarding treatment methods and prognosis.

This is a report of pulmonary actinomycosis which has been treated with long chemotherapy under the misdiagnosis of pulmonary tuberculosis for 14 years and has finally diagnosed by the specimens of excised lung. Pulmonary actinomycosis is very few in recent report by the use of penicillin and sulfonamide, but for the difficult differential diagnosis with pulmonary tuberculosis and carcinoma, It is a choice of treatment for resect for the localized lesions.
