Primary myoepithelial carcinoma of the lung: a rare entity treated with parenchymal sparing resection

Primary lung myoepithelial carcinomas are rare neoplasms arising from the salivary glands of the respiratory epithelium. Given the rare occurrences and reports of these tumors, appropriate recommendations for resection are difficult to formulate. Although classified as low-grade neoplasms, these tumors have a significant rate of recurrence and distant metastasis

Preserving T2 in Thoracic Sympathicotomy for Palmar Hyperhidrosis: Less Tissue Trauma, Same Effectiveness

WOS: 000294662500007PubMed ID: 21409744Background: The aim of this study was to compare two different sympathicotomy procedures for primary hyperhidrosis in terms of compensatory sweating, complications, safety and effectiveness. Methods: The data of 78 consecutive patients who underwent bilateral endoscopic thoracic sympathicotomy (156 laterals) for palmar hyperhidrosis between January 2005 and September 2009 were studied retrospectively. The first 29 consecutive patients were treated with a T2-3 sympathicotomy (Group A). After November 2007, all patients (49 patients) were treated with a T3 sympathicotomy alone (Group B). The chest tubes were always removed after checking for pneumothorax with roentgenography. All patients were followed up and evaluated for results, side effects, complications, and satisfaction levels. The differences between the two groups were analyzed. Results: The mean age of the 47 (60.2%) female and 31 (39.8%) male patients was 25.2 years. Horner's syndrome and pneumothorax was not detected in either group. The mean follow-up time was 20.82 months (6-52 months). Effectiveness of the procedure at the time of discharge and at follow-up was 100% and 97.5%, respectively. There was no significant difference between groups with regard to any analyzed parameter. Conclusion: This study demonstrates that preserving the T2 ganglion is safe, and does not compromise the effectiveness of the procedure. Sympathicotomy has the same success rate as sympathectomy, but requires significantly less dissection and results in less tissue trauma

Myoepithelioma of the lung

WOS: 000086612800022PubMed ID: 10731657A 54-year-old woman with myoepithelioma, a very rare tumor of the lung, is reported. The patient presented with exertional dyspnea, cough and intermittent pleuritic chest pain. Her chest X-ray revealed a peripheral 2 cm mass in the left lower lung zone. Bronchoscopy was normal. She underwent thoracotomy in which a wedge-resection was performed. Histological examination of the specimen demonstrated myoepithelioma of the lung. (C) 2000 Elsevier Science B.V.

Comparison of rigid and flexible transbronchial needle aspiration in the staging of bronchogenic carcinoma

Annual Meeting of the European-Respiratory-Society -- SEP 16-20, 1995 -- BARCELONA, SPAINWOS: 000077319000004PubMed ID: 9817958In staging bronchogenic carcinoma by transbronchial needle aspiration (TBNA), rigid histology needles are generally preferred to flexible cytology needles owing to the widespread opinion that rigid needles have higher diagnostic yield and less false-positive results. The objective of this study was to compare the efficacy and safety of the rigid and flexible TBNAs in staging bronchogenic carcinoma to establish whether a flexible cytology needle method can replace the rigid needle. A prospective study was conducted in 138 consecutive patients with extra- or endobronchial masses suggestive of bronchogenic carcinoma and amenable to surgical procedures. All 8 mm and larger paratracheal, carinal, hilar and/or main bronchial lymph nodes determined before bronchoscopy by computed tomography (CT) were sampled by successive 18-gauge rigid and 21-gauge flexible TBNAs in the same session. The anatomic landmarks were followed precisely during TBNAs, and a proper technique applied in sampling and specimen processing. Malignant lymph node involvement was specified in 97 (72%) cases of bronchogenic carcinoma by rigid, and in 89 (66%) by flexible TBNA. There were 4 (100%) benign cases (3 with tuberculosis and 1 with sarcoidosis) of 101 (73%) with positive rigid TBNAs (82 with histological and 19 with cytological specimens). TBNAs determined malignant lymph node involvement :in a total of 104 (78%) patients. Of 30 TBNA-negative patients, 14 were proven to have false-negative TBNAs by mediastinoscopy/mediastinotomy/minithoracotomy, and 16 to have true-negative TBNAs by thoracotomy. Thoracotomy confirmed true positivity in 52 rigid and 49 flexible TBNAs, and false negativity in 4 rigid and 7 flexible TBNAs. Further staging was confirmed in these 7 cases. Four had proven false negative results by both methods. The presence of small cell carcinoma (21) or N-3 disease (27) presented a contraindication to thoracotomy in 48 TBNA-positive patients. Adequate-quality and malignant lymph node specimens were more frequently obtained by both techniques at advanced tumor and node stages. However, malignant lymph node invasion was significantly more frequent in rigid and flexible TBNA specimens only in the presence of advanced tumor status and abnormal endoscopic appearance. The sensitivities of rigid and flexible TBNAs were 74 and 70%, respectively (p > 0.05), but both had a specificity of 100%. Neither false-positive results nor serious complications other than hemorrhage of 30-100 mi (rigid: 5%, flexible: 2%)were encountered with either technique. These results indicate that in bronchogenic carcinoma, hilar and mediastinal lymph nodes can be staged by 21-gauge flexible TBNA (76%) as accurately as by 18-gauge rigid TBNA (79%) if a proper technique is applied and anatomic landmarks are followed precisely (p > 0.05).European Resp So

Giant benign fibrous tumor of the pleura in a pregnant woman: Report of a case

WOS: 000182151900006PubMed ID: 12658385While most pleural neoplasms are malignant and associated with asbestos exposure, benign tumors may also occur. Benign fibrous tumors of the pleura are rare and, unless diagnosed and resected early, they may reach an enormous size and cause severe symptoms. We report the case of a pregnant woman with a giant benign fibrous tumor localized in the pleura
