Kaposi's sarcoma (KS) is a multicentric human immunodeficiency virus-associated neoplasm characterized by multiple vascular nodules in the skin, mucous membranes, and viscera. Gastrointestinal acquired immunodeficiency syndrome (AIDS)-related KS is the most common visceral involvement reported in disseminated disease. Here, we present the findings of a rare case of KS involving multiple organs with abdominal pain and active bleeding in the colon. Multiple intraluminal lesions were found in the terminal ileum, sigmoid colon, and rectum by ileocolonoscopy, and in the jejunum and ileum by fluoroscopy. Abdominopelvic CT revealed multiple enhanced flat lesions in the ileum and enlarged lymph nodes. The diagnosis was confirmed by histopathology, and antiretroviral therapy was initiated as the treatment of choice for KS. Owing to the increasing number of AIDS patients, it is essential for radiologists and clinicians to be aware of the imaging characteristics of KS to protect physicians from indiscriminate exposure to AIDS.

Sleeve pneumonectomy can be a method of treatment in a selected patient with bronchogenic carcinoma involving carina. A 64 years old male with a history of mitral valve replacement via midsternotomy 13 years ago and resection of papilloma of the vocal cord 2 years ago. The patient was admitted due to blood-tinged sputum. Bronchoscopy and computerized tomogram of the chest revealed 3.5 cm mass at lower margin of the trachea and totally obstructing the left main bronchus. A biopsy revealed squamous cell carcinoma. He underwent left sleeve pneumonectomy through sequential bilateral thoracotomy without cardiopulmonary bypass, and the pathologic stage was T4N0M0 stage IIIB. The patient is being followed through the outpatient clinic in good general condition.

Purpose: Mass can compress around tissue and cause deviation of normal anatomical structures. Often, mass grows toward neurovascular pedicle and encircles depending on the nature of mature mass. Neglecting neurovascular involvement of the mass is a serious problem not to be overlooked. Authors have performed microscopic approach regarding mass involving the neurovascular pedicle in the hand. Materials and Methods: From January 2007 through February 2012, retrospective analysis for nine cases of mass involving neurovascular pedicles was done. Patients were evaluated preoperatively by ultrasonography or MRI and checked intraoperative finding. Masses were evaluated by site, preoperative evaluation, involved neurovascular pedicle, histopathologic diagnosis, complication, and recurrence. Results: The site of mass involving neurovascular pedicles was 4 cases on the wrist, 2 cases on the palm, 2 cases on the finger, 1 case on the hand dorsum. Involved neurovascular pedicles were 3 radial arteries and nerves, 3 proper digital arteries and nerves, 1 radial artery, 1 superficial branch of radial nerve, 1 common digital artery and nerve. The histopathologic diagnosis of mass were 3 ganglions, 2 giant cell tumors, 2 epidermal cysts, 1 fibroma, and 1 benign spindle tumor. There were 2 cases of recurrence and secondary excisions were performed. Conclusion: Neurovascular pedicle injury can lead to serious complication like sensory and motor disorders, distal part ischemia, and so on. In case of mass suspected neurovascular invasion, accurate preoperative evaluation such as ultrasonography or MRI is necessary. To prevent any neurovascular related complication during mass excision, delicate surgical technique using a microscope becomes essential.

A 77-year-old man presented with a huge protruding mass on the left anterior chest wall. The tumor was resected and diagnosed as dermatofibrosarcoma protuberans (DFSP). DFSP is an uncommon, intermediate-grade mesenchymal cutaneous tumor which extends deep into subcutaneous tissue and may invade through the fascial planes and into muscle but rarely metastasize. Histologically, DFSP is composed of spindle cells arranged in an irregularly whorled or storiform pattern. The histological diagnosis can be confirmed with immunohistochemical staining for CD34. We report a case of DFSP. The tumor was completely excised and the chest wall was reconstructed using latissimus dorsi muscle flap and skin graft.

A 15-year-old male was admitted with right-sided chest pain and cough for one month. On chest computed tomographic scan, a $10\times15\times16$ em-sized huge mediastinal mass was occupied in the right hemithorax. Radiologically, it seemed that the tumor was severely adhesive on the heart and the superior vena cava. Therefore we decided on chemotherapy and radiotherapy first instead of surgery. The tumor marker was nearly normalized afterwards, but the tumor size was seemed to be bigger on chest tomographic scan. This suggests the growing teratoma syndrome. After the successful resection, he showed symptomatic improvement and is being followed up without any symptoms in an out patient department up to now.

Congenital cystic adenomatoid malformation of the lung is a rare pulmonary malformation, Although it is one of the most common congenital anomalies which cause acute respiratory distress in the newborn infants, characterized by marked proliferation of terminal respiratory structures. We have experienced an unusual case of congenital cystic adenomatoid malformation associated with pectus excavatum. The patient was 3-year-old female who suffered from cough and high fever for 20 days, and antibiotic therapy was given in other hospital before transfer to our hospital. The findings on chest X-ray, chest CT, aortogram, and selective bronchial arteriogram showed cystic lesions in the right upper and middle lobe accompanied but severe pectus excavatum. Right bilobectomy for pulmonary lesion and costosternal elevation for pectus excavatum was performed simultaneously with successful result. The postoperative course was uneventful and the patient was discharged on the twentieth postoperative day.

This is a report of a successful management of a patient with infective endocarditis involving native aortic valve, mitral valve, tricuspid valve, and Interventric lar septum. A 16 year-old patient who underwent VSD patch closure, and aortic valvuloplasty at the age of 1 1 years showed Intractable congestive heart failure during antibiotics treatment for infective endocarditis. Operative findings revealed that there were large defect along the previous patch, aortic regurgitation with multiple perforations and vegetations, mitral regurgitation with vegetation, aortic paraannular abscess, interventricular myocardial abscess, and tricuspid regurgitation with perforations and vegetations. We reconstructed the interventricular defect with Dacron patch extending to the aortic valve annulus after radical debridement of all infected or devitalized tissues, and could implant aortic valve by anchoring to the reconstructed Dacron patch. Mitral valve was replaced and tricuspid valve was repaired with patient's own pericardium. The patient was discharged after antibiotics treatment for 6 weeks and in good condition without any sequelae for 12 months.

Chronic granulomatous disease in childhood is a rare inheritable disorder of phagocytic cells in which defective production of the reactive intermediates of oxygen predisposes the patient to severe recuring pyogenic infections. The lung is the most common site of infection and pulmonary disease is the primary cause of death for greater than 50% of children with chronic granulomatous disease. Although the role of surgery in management of this disease remains undefined, rapid diagnosis of the underlying pulmonary problem is crucial to determine the most appropriate antimicrobial therapy and surgical techniques such as lobectomy of involved areas lead to more rapid recovery and thus allow the antibiotics to be more efficacious in these cases. We have treated a one month old male baby who had the chronic granulomatous disease with pulmonary infection. Wide surgical resection of the affected lobe and use of antibiotics and antifungals were carried out with good clinical results. He was well after the operation.

Renal cell carcinoma involves the inferior vena cava(IVC) in approximately 5-10% of the patients. Presently surgical extirpation is the only form of therapy that can result in cure. Circulatory arrest with cardiopulmonary bypass is an operative technique that recently has been used to assist in resection of tumors that extend into the vena cava above the level of hepatic veins. We performed removal of tumor thrombi of IVC in 4 patients. All of them who had the renal cell carcinormas with infrahepatic vena caval extension were performed by standard surgical technique without cardiopulmonary bypass. But in one patient, inferior vena caval thrombectomy was done using circulatory arrest because of the recurred extension of the tumor thrombi within the vena cava above the insertion of the hepatic vein. All patients were recovered without any significant problems.

Membranoproliferative glomerulonephritis (MPGN) is a progressive primary glomerulonephritis characterized by mesangial proliferation with increased mesangial matrix, subendothelial immune deposits, mesangial interposition and a double contour feature of the glomerular basement membrane. The glomerular involvement in MPGN is usually diffuse, however, cases of focal or segmental MPGN have been reported by several authors. We report a case of focal segmental MPGN with prolonged hypocomplementemia for ,3 years in a 5 years old girl. (J Korean Soc Pediatr Nephrol 2005;9:237-244)
