In 1904, Albrecht first used the term "hamartoma" to refer to a congenital abnormal mixing of the normal components of an organ and is applied also to tumors found in many organs other than the lung. Though the term "hamartoma" of the lung have been used with the connection to the presence of cartilage, tumors that do not contain cartilagenous compont is also considered hamartoma. The authors experienced one case of endobronchial hamartoma. The patient, a 42-year-old woman, a teacher in a primary school, was admitted to our hospital with frequent attacks of hemoptysis. Bronchogram on the left disclosed abrupt blocking of bronchial filling at the bifurcation between postero-basal and lateral basal segmental bronchial substantiating a mass in the bronchial lumen. Left lower lobectomy was performed. The answer of pathology was benign endobronchial hamartoma. Postoperative course was uneventful. Discharged on 19th postoperative day.

Leiomyosarcoma of the mediastinum and primary leiomyosarcoma of the spine are exceedingly rare. In most cases, spinal leiomyosarcoma is metastatic. In this report, we describe the case of a 58-year-old man who presented with a large leiomyosarcoma of the posterior mediastinum that extended into the adjacent spinal canal. The tumor was completely resected from the mediastinum, but only subtotally removed from the spinal canal because the spinal mass had tightly invaded the spinal cord. Because the patient's postoperative condition was poor, no adjuvant radiotherapy or chemotherapy was administered. He expired 3 months after the surgery due to relapse; the spinal and mediastinal tumor remained at the preoperative size.

By radioimmunoassay, serologic markers of Hepatitis B Virus were studied in 44 patients with acute viral hepatitis, 10 patients with chronic persistent hepatitis, 10 patients with chronic active hepatitis, 44 patients with liver cirrhosis and 25 patients with primary hepato cellular carcinoma. The results were follows: 1) HBsAg was present in 77.2% of AVH, 40% of CPH, 80% of CAH, 55.1% of LC and 68 % of PHC. In this HBsAg positive groups, all but one in liver cirrhosis had Anti-HBc. 2) Anti-HBs was most commonly detected in CPR and accompanied by Anti-HBc except one case in AVH. 3) Anti-HBc was the only marker detected in 11.4% of AVH, 20% of CPH, 20% of CAH, 16.3% of LC and 8% of PHC. 4) HBeAg was most commonly found in HBsAg-positive CPH but Anti-HBe was most frequently detected in PHC. 5) The absence of HBV markers was noted in 2.3% of AVH, 10% of CPH, 8% of PHC except CAH and LC.

The omental pedicle flap[OFF] has been used for management of complicated problems in various fields of cardiovascular surgery. Its unique properties of enhancing neovascularity, relieving lymphedema, providing fibroblasts to promote healing, providing soft tissue coverage, & functioning in the face of existing infection make it ideal in managing many of the more complicated problems facing the thoracic surgeon. We have used omental pedicle for colosing of the bronchial fistula R esophageal fistula with filling the adjoining cavity after pneumonectomy. The successful closure of the bronchial stump with OFF were obtained in 2 cases, but one case was failed who was suffered from the esophageal fistula. The primary operation in each cases were right pleuropneumonctomy for tuberculous empyema in 2 cases & left pneumonectomy for chronic empyema in 1 case, We believe that the OFF is effective for closing fistula due to postoperative empyema k plombage procedures for dead space of infected thoracic cavity.

Herpes simplex virus type 2 (HSV2) meningitis primarily develops during or following a primary genital HSV2 infection that was acquired from sexual contact or through the birth canal during delivery from mother. We describe a 15 year old virgin without history of previous herpes simplex infection who developed 2 episodes of HSV2 meningitis. Although recurrent meningitis due to HSV is primarily seen in young or sexually active adults. HSV2 meningitis should be in the differential diagnosis of recurrent meningitis in adolescent patients.

We report a case of vegetation in a 4-year-old female with infective endocarditis, diagnosed by late gadolinium-enhanced (LGE) cardiovascular magnetic resonance (CMR) imaging. The patient had a history of primary closure for ventricular septal defect and presented with mild febrile sensation. No remarkable clinical symptoms or laboratory findings were noted; however, transthoracic echocardiography demonstrated a 14 mm highly mobile homogeneous mass in the right ventricle. On LGE CMR imaging, the mass showed marginal rim enhancement, which suggested the diagnosis of vegetation rather than thrombus. The extracellular volume fraction (${\geq}42%$) of the lesion was higher than that of normal myocardium. Based on the patient's clinical history of congenital heart disease and pathologic confirmation of the lesion, a diagnosis of infective endocarditis with vegetation was made.

Interventional device closure has emerged as a less invasive alternative to surgery in the management of paravalvular leakage. However, this procedure involves various problems such as a high probability of residual leakage or hemolysis. Here, we report a case of residual paravalvular leakage despite two attempts at interventional closure in a patient with a history of four previous mitral valve replacements. The fifth operation for the primary repair of paravalvular leakage was performed successfully. Careful evaluation before the procedure and specially designed devices are essential for the interventional treatment of paravalvular leakage. Surgery can be performed adequately in the management of paravalvular leakage even in high-risk patients.

Pulmonary arteriovenous malformation (PAVM) is a rare anomalous direct communication between the pulmonary artery and vein with a considerable risk of serious complications such as cerebral thromboembolism or abscess and pulmonary hemorrhage. Although the past, surgical resection such as lobectomy was mostly used to treat PAVM, the recent development of endovascular treatment has made it a primary consideration to perform transcatheter embolization using coils or detachable balloons. We report a case of successful transcatheter embolization of giant PAVM with the second generation Amplatzer vascular plug II as a new self-expanding device.

Background/Aims: Endoscopic mucosal resection (EMR) is the primary treatment for duodenal adenomas; however, it is associated with a high risk of perforation and bleeding, especially with larger lesions. The goal of this study was to demonstrate the feasibility and safety of endoscopic suturing (ES) for the closure of mucosal defects after duodenal EMR. Methods: Consecutive adult patients who underwent ES of large mucosal defects after EMR of large (>2 cm) duodenal adenomas were retrospectively enrolled. The OverStitch ES system was employed for closing mucosal defects after EMR. Clinical outcomes and complications, including delayed bleeding and perforation, were documented. Results: During the study period, ES of mucosal defects was performed in seven patients in eight sessions (six for prophylaxis and two for the treatment of perforation). All ES sessions were technically successful. No early or delayed post-EMR bleeding was recorded. In addition, no clinically obvious duodenal stricture or recurrence was encountered on endoscopic follow-up evaluation, and no patients required subsequent surgical intervention. Conclusions: ES for the prevention and treatment of duodenal perforation after EMR is technically feasible, safe, and effective. ES should be considered an option for preventing or treating perforations associated with EMR of large duodenal adenomas.

Solitary fibrous tumor of the pleura (SFTP) is a rare primary intrathoracic tumor that arises from mesenchymal tissue underlying the mesothelial layer of the pleura. It usually has an indolent clinical course. The hypoglycemia that accompanies SFTP was first described by Doege and Potter independently in 1930, hence the eponym Doege-Potter syndrome (DPS). The incidence of DPS is reported to be ~4%. In this report, we present a typical case of DPS that was cured through complete surgical resection.
