Prosthetic reconstruction of musculoskeletal defects about the knee for tumor has many advantages, particularly the maintenance of motion and immediate functional restoration. But, prosthetic reconstruction has inherent limitations in terms of long-term durability. The authors have reported here a patient who had mechanical failure at 61 months later following use of a modular resection system to reconstruct the segmental defect of proximal tibia in osteosarcoma. In this case, another technique of extensor mechanism reconstruction using Achilles tendon allograft was attempted. Because of the concerns involving durability of tumor prosthesis, increased emphasis has to be placed on innovation in prosthetic design.

A newborn male baby was transferred to our hospital with a left inguinal mass. The mass was huge measuring $10{\times}10cm$, engorged, and dark-blue colored as a result of internal hemorrhage. Unstable vital signs were combined with DIC and acute renal failure. Emergency operation was performed because of the suspicion of bowel perforation. The peritoneal cavity was full of ascitis and the distal jejunum had a 0.5 cm perforation. Segmental resection of the jejunum and incisional biopsy of the inguinal mass were performed. On pelvic and thigh MRI, the mass protruded into pelvic cavity and encircled large vessels and nerves of the thigh. Pathologic diagnosis was congenital infantile fibrosarcoma. Fifteen days after operation, primary tumor excision was undertaken. The second look operation, performed after 6 times VAC chemotherapy, revealed no remained malignant cell on microscopic section. The baby has been followed closely for the last eight months.

A glomus tumor is an uncommon soft tissue tumor that is most commonly found in the subungual area and a glomus originating in the trachea is extremely rare. Histologically and ultrastructurally, these tumors have been divided into three subtypes: classic glomus tumors, glomangiomas, and glomangiomyomas. Glomangiomyomas account for less than 10% of all glomus tumors and are the least common type. We report a case of a 54-year-old man with glomangiomyoma of the trachea who presented with stridor. We treated the tumor by segmental resection and primary repair via a transcervical approach.

Small bowel injury resulting from unforeseen penetration of the anterior annulus fibrosus and longitudinal ligament is a rare complication of lumbar microdiscectomy. The patient complained of abdominal tenderness and distention immediately after microdiscectomy for L4-5 and L5-S1 disc herniation. Using abdominal computed tomography, we found several foci of air overlying the anterior aspect of the vertebral body at the L5-S1 level. Segmental resection of the small bowel including small tears and primary anastomosis of the jejunum were performed. Here, we present a case of intestinal perforation after lumbar microdiscectomy and discuss technical methods to prevent this complication with a review of literature.

Neurilemmoma is a benign and slowly growing neurogenic tumor. Intrathoracic neurilemmoma often develops in the chest wall and posterior mediastinum, but endobronchial neurilemmoma is extremely rare. The diagnosis of endobronchial neurilemmoma with preoperative imaging findings is challenging and is usually made via postoperative pathological examination. These authors encountered a case of primary endobronchial neurilemmoma in a 52-year-old woman who had no symptoms. A $3.0{\times}2.6$ cm mass in the right lower lobe projecting into the mediobasal segmental bronchus was shown in the results of the contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) of the chest. Benign neurilemmoma was confirmed via bronchoscopic biopsy, and surgical resection (sleeve bronchial excision and end-to-end anastomosis) was performed.

Mucoepidermoid carcinoma of the lung is extremely rare. This rare tumor arise beyond the carina, usually main stem bronchi, but occasionally in lobar or segmental airways, This tumor presents with symptoms of bronchial irritation or obstruction. Distant metastasis is an uncommon, therefore complete surgical resection is the treatment of the choice. The prognosis of this tumor correlates with the histologic grade of the tumor. We experienced a case of mucoepidermoid carcinoma arising from the right middle lobe, which was treated with the right middle lobectomy, with good result. We report this case and follow-up of the patient.

From Jan. 1981 to Dec. 1993, 24 cases of pulmonary hamartoma were experienced sugically at the Department of Thoracic Surgery, College of Medicine, Seoul National University. They consisted of 11 females and 13 males. The age distribution was 24 years to 71 years with a mean age of 49 years. They included 3 cases of endobronchial hamartoma, and 21 cases of pulmonary parenchymal hamartoma. Fifty eight percent of patients [14/24] were asymptomatic. One patient had a multiple pulmonary parenchymal hamartoma, and 1 patient also had combined lung cancer. The operative procedures were 9[37.5%] wedge resections, 5[20.8%] lobectomies, 3[12.5%] enucleations, 3[12.5%] segmental resections, 2[8.3%] bilobectomies, 1[4.2%] lobectomy and segmentectomy, and 1[4.2%] lobectomy, wedge resection, and enucleation. All of the operative results were excellent and without complication.

Congenital bronchial atresia is one of the rare bronchopulmonary anomalies which is thought to be caused by a vascular insult of uncertain timing during fefal development. It is defined as an anomaly which does not have communication between a segmental or lobar bronchus a'nd the main airway. Because of the collateral ventilation, almost all of these cases show hyperlucency of the involved segment or lobe in chest roentgenogram. We report an extremely rare case of congenita bronchial atresia with collapse of the right upper lobe which was treated by surgical resection.

Segmental mandibulectomy causes severe functional disability and cosmetic problem. Many methods of reconstruction have been used but none of these procedures provides the ideal solution. There has been increased interest in the possibility of preserving a portion of the mandible and still carrying out a adequate tumor resection. We experienced four cases of marginal with sagittal mandibulectomy in patients with floor of mouth. buccal. and soft palate carcinoma, and sagittal mandibulectomy in 8 patients with tonsillar carcinoma and a case of marginal mandibulectomy in tonsillar cancer patient. In all cases mandible facing the tumor were successfully resected and repair of the mandible. postoperative facial contour were satisfactory. We think. that these sagittal procedures are oncologically sound in its removal of tumor. biomechanically secure and maximize postoperative rehabilitation while maintaining the normal contour of the face.

The association of pyloric atresia and epidermolysis bullosa(EB) in newborn is rare and inheritant as an autosomal recessive trait. We report a newborn girl with pyloric atresia and epidermolysis bullosa. Blisters were noted on her skin at birth, especially in pressure-exposed area, and later on the oral mucosa. Junctional epidermolysis bullosa was confirmed by light microscopy and electron microscopy. Radiography revealed pyloric atresia. Segmental resection of 1.5 cm and gastroduodenostomy were carried out at 4 days of age. Protein loosing enteropathy developed after oral feeding. The frequency of episodes of nonscarred blisters and the severity and duration improved significantly with time. The protein loosing enteropathy was persistent, and at 1 year of age, her growth is markedly retarded.
