1/59. Pleuropulmonary blastoma in an adult: an initial case report.BACKGROUND: Pleuropulmonary blastoma (PPB) is a unique dysontogenetic neoplasm of childhood. Its primitive, sarcomatous features are analogous to those of other dysembryonic or dysontogenetic tumors, such as wilms tumor, hepatoblastoma, neuroblastoma, and embryonal rhabdomyosarcoma. PPB typically presents in young children, most younger than 5 years, as a pulmonary and/or pleural-based tumor with cystic, solid, or combined cystic and solid features. These neoplasms are characterized histologically by primitive mesenchymal or a mixture of primitive and sarcomatous components and generally have an unfavorable clinical outcome: death occurs within 1-2 years after diagnosis. methods: Clinicopathologic and radiographic findings of a man age 36 years with a cystic and solid mass in the left hemithorax were reviewed and compared with previously studied cases of PPB. RESULTS: Pathologic examination of the mass revealed a cystic and solid neoplasm composed of malignant mesenchymal cells that were immunoreactive for vimentin and muscle specific actin and focally for desmin. The architectural and cytologic appearances as well as the immunohistochemical profile were those of type II PPB. CONCLUSIONS: To the authors' knowledge, all previously reported cases of PPB occurred in children age 12 years or younger. They believe that this case represents the first occurrence of PPB in an adult and documents the finding that, although it is uncommon, adults can develop primitive neoplasms that are usually associated with the pediatric population. In addition, the clinicopathologic features observed in the authors' adult patient were consistent with their experience with this tumor type in children. The patient died less than 1 year after diagnosis.- - - - - - - - - - ranking = 1keywords = muscle, neoplasm (Clic here for more details about this article) |
2/59. Intrathoracic application of the reverse latissimus dorsi muscle flap.The use of the reverse latissimus dorsi muscle flap based on its paraspinous perforators for posterior trunk wound coverage has been described previously. However, few studies have reported its intrathoracic application. In this study the authors present their experience in treating 3 patients with various intrathoracic defects using the reverse latissimus dorsi muscle flap. There were 1 male and 2 female patients who ranged in age from 4 to 74 years (mean, 49 years). The etiology included an infected aortic graft, a bronchopleural fistula, and a recurrent congenital diaphragmatic hernia. Follow-up ranged from 2 to 24 months. Successful outcomes were achieved in all 3 patients, and there was no recurrence or wound complication identified. Their results demonstrate the versatility and reliability of the reverse latissimus dorsi muscle flap in treating low posterior intrathoracic defects.- - - - - - - - - - ranking = 6.3294160725918keywords = muscle (Clic here for more details about this article) |
3/59. Utilization of muscle flaps in the treatment of bronchopleural fistulas.This paper reports the results of a series of 5 patients who underwent closure of persistent bronchopleural fistula using extrathoracic muscle flaps over a 6-year period. All patients had failed more conservative treatment. The surgeries were one- or two-stage procedures performed with the collaboration of cardiovascular and reconstructive surgical staffs. There were no associated mortalities. The muscle flaps utilized were the latissimus dorsi, serratus anterior, pectoralis major, pectoralis minor, and trapezius. The results have been encouraging and allowed the complete closure of the bronchopleural fistula in the majority of patients. The authors present the best management of this serious disease, as well as its pathophysiology and clinical aspects.- - - - - - - - - - ranking = 5.4252137765073keywords = muscle (Clic here for more details about this article) |
4/59. Late esophagopleural fistula after left pneumonectomy: report on one case.Esophagopleural fistula is an uncommon complication of pneumonectomy. Late nonmalignant esophagopleural fistula after left pneumonectomy for lung cancer is exceedingly uncommon. We report on one patient who developed such a fistula 33 months after the operation. signs and symptoms were first attributed to infection of the thoracotomy incision and diagnosis was made only after detection of some food coming from the pleural space. thoracostomy, enteral feeding by a percutaneously placed gastrostomy tube and myoplasty allowed both closure of the fistula and obliteration of the pleural space.- - - - - - - - - - ranking = 0.2173749459617keywords = cancer (Clic here for more details about this article) |
5/59. Video-assisted thoracoscopic treatment for pleuroperitoneal communication in peritoneal dialysis.Massive hydrothorax is an uncommon but well-recognized complication of continuous ambulatory peritoneal dialysis (CAPD). We performed a video-assisted thoracoscopic resection of the pleuro-peritoneal communication and pleurodesis in a patient with massive right hydrothorax secondary to CAPD. Histologically, the resected diaphragm was lacking in common tissue, tendons and skeletal muscle tissues, is displaced to fibrous connective tissue. These anatomic findings suggested that the cause of communication was congenital diaphragmatic change. Video-assisted thoracoscopic treatment facilitated efficient inspection and easy resection of the weak portion of the diaphragma in the case of pleuroperitoneal communication.- - - - - - - - - - ranking = 0.90420229608455keywords = muscle (Clic here for more details about this article) |
6/59. The use of a Dumon stent for the treatment of a bronchopleural fistula.We report the successful management of a bronchopleural fistula with bronchial stent placement combined with irrigation of the empyema cavity. A bronchopleural fistula occurred in a 67-year-old man after a right upper lobectomy for lung cancer. Resuturing of the bronchial stump plus omental wrapping and subsequent closure of the open stump with a pedicled flap of intercostal muscle were not effective. Consequently, we placed a Dumon stent in the right main bronchus to close the stump.- - - - - - - - - - ranking = 1.1215772420462keywords = muscle, cancer (Clic here for more details about this article) |
7/59. Endoscopic closure of bronchopleural fistula after pneumonectomy by submucosal injection of polidocanol.We report two cases of a bronchopleural fistula with, and without, empyema treated by endoscopic submucosal injection of polidocanol (sclerotherapy) and application of cyanoacrylate. Case 1: A 60-year-old man underwent left pleuropneumonectomy for lung cancer. He developed bronchopleural fistula with empyema at 32 days after the operation. We performed sclerotherapy around the fistula. The air leakage stopped at 2 weeks after the sclerotherapy, and the fistula was closed. He was eventually cured of the empyema by pleural drainage. Case 2: A 61-year-old man underwent left pneumonectomy for lung cancer. He developed bronchopleural fistula without empyema at 50 days after the operation. We performed sclerotherapy and application of cyanoacrylate. After this therapy, the air leakage stopped immediately, and the bronchopleural fistula was closed. The sclerotherapy and application of cyanoacrylate are not only technically easy, but also very effective for treatment of bronchopleural fistula. sclerotherapy and cyanoacrylate may be advocated as a first therapeutic step.- - - - - - - - - - ranking = 0.4347498919234keywords = cancer (Clic here for more details about this article) |
8/59. An intrapulmonary chondromatous hamartoma penetrating the visceral pleura: report of a case.A 65-year-old woman had been followed up for a hamartoma-like mass in the right upper lobe of the lung since 1995. A follow-up CT scan showed an increase in the size of the lesion and a new lesion next to the old mass, which was highly suspected to be lung cancer. A right upper lobectomy was thus performed in May 2000. The hamartoma penetrated the visceral pleura, and adhered to the mediastinal pleura. Such a growing hamartoma with pleural invasion has so far rarely been previously reported.- - - - - - - - - - ranking = 0.2173749459617keywords = cancer (Clic here for more details about this article) |
9/59. Delayed closure of persistent postpneumonectomy bronchopleural fistula.A 73-year-old man with a history of postpneumonectomy empyema and a long-term chest tube since 1979 presented with fever, chills, leukocytosis, and purulent fluid from the left tube thoracostomy. CT scan and bronchoscopy demonstrated a right lower lobe pneumonia and a left mainstem dehiscence with direct communication to the left tube thoracostomy. He underwent primary closure of the bronchopleural fistula with latissimus dorsi muscle flap coverage after antibiotic therapy for right lower lobe pneumonia.- - - - - - - - - - ranking = 0.90420229608455keywords = muscle (Clic here for more details about this article) |
10/59. Simultaneous bronchopleural and esophagopleural fistulas after pneumonectomy.The simultaneous occurrence of bronchopleural fistula (BPF) and esophagopleural fistula (EPF) after pneumonectomy is very rare. We describe a 60-year-old man who developed empyema associated with bronchopleural fistula as a complication of a right pneumonectomy. Initial chest tube drainage and antibiotic therapy were ineffective. Five months later ingested food particles appeared in the drainage fluid. esophagoscopy revealed an esophageal fistula of 10 mm in diameter. After nutritional support by feeding jejunostomy both BPF and EPF were repaired by subscapular muscle myoplasty and extensive thoracoplasty through a right thoracotomy. Endoscopic examination performed 1 month after surgery showed complete closure of both fistulas and 9 months after surgery the patient was eating and gaining weight. The patient's death was due to aspiration pneumonia of another origin.- - - - - - - - - - ranking = 0.90420229608455keywords = muscle (Clic here for more details about this article) |
