1/26. Bronchial capillary hemangioma in adults.Two cases with capillary hemangioma of the trachea and the left upper lobe bronchus are presented. The adult patients were referred to the hospital because of hemoptysis and cough. The chest radiographs were normal in both cases. The bronchoscopic examination revealed circumscribed lesions with a capillarized surface protruding into the lumen of the trachea and the left upper lobe bronchus, respectively. The lesions were excised in toto with flexible bronchoscopic forceps. The specimens contained typical capillary hemangiomas without any signs of malignancy. Capillary hemangioma in the bronchial tree is an extremely rare benign lesion in adults. Nevertheless, it should be considered as a possible cause of hemoptysis and cough.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
2/26. Primary lymphoplasmacytoid lymphoma of the trachea with immunoglobulin g paraprotein.A primary tracheal lymphoma with immunoglobulin g (IgG)-associated monoclonal serum paraprotein treated with surgery and chemotherapy is reported. As far as we know this is the first lymphoplasmacytoid lymphoma reported in the tracheobronchial tree and the first with a serum and tissue IgG monoclonal paraprotein. Differential diagnosis must be made essentially with extramedullary plasmacytoma and mucosa-associated lymphoid tissue lymphoma. CD-45RB strong positivity and the absence of lymphoepithelial lesions may help to differentiate lymphoplasmacytoid lymphoma from them. We expand the spectrum of lymphoid lesions with plasmacytoid features that can occur in the tracheobronchial tract.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
3/26. Tracheal polyp.Benign tumors of the tracheobronchial tree are extremely rare. A case of a benign inflammatory endotracheal polyp and literature review are presented, including classification and treatment options. Although rare, these lesions must be efficiently diagnosed and expeditiously removed to prevent airway occlusion or irreversible pulmonary disease.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
4/26. Flexible argon plasma coagulation treatment of obstructive tracheal metastatic melanoma.Metastases to the tracheobronchial tree may be considered rare, and melanoma metastases to the trachea are very uncommon. We here report the case of a 61-year-old woman with metastatic melanoma to the trachea occurring 2 years after the excision of a right shoulder skin nodule. The patient underwent argon plasma coagulation (APC) recanalization of the malignant airway under flexible bronchoscopy, which led to the stable resolution of the respiratory symptoms. We also discuss the possible palliative therapeutic options for such metastases, including the APC technique.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
5/26. Massive hemoptysis caused by tracheal hemangioma treated with interventional radiology.Capillary hemangiomas of the tracheobronchial tree are extremely rare in adults, with hemoptysis being one of the most serious forms of presentation. An operation has been the treatment of choice, although it does involve high rates of morbidity and mortality, especially in emergency situations such as massive hemoptysis, which has led to the search for other therapeutic alternatives. There is no experience with embolization by interventional radiology when the hemoptysis is tracheal in origin, caused partly because the infrequency of this pathology; however, the foundations for it have been laid with the development of embolization for bronchopulmonary pathology. We report a case of a tracheal capillary hemangioma in a 66-year-old woman diagnosed with idiopathic thrombopenic purpura, which began as a massive hemoptysis and was treated successfully with embolization by interventional radiology. There has been no recurrence of the bleeding after 1 year's follow-up, and the patient's control fibrobronchoscopy is normal.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
6/26. Primary endotracheal neurogenic tumors.Benign tumors in the tracheobronchial tree are rare. We report two cases of primary endotracheal neurogenic tumors in patients who presented insidiously. Both patients did not manifest other clinical features of neurofibromatosis (Von Recklinghausen's disease). A single procedure using rigid bronchoscopy and neodymium: yttrium-aluminum-garnet laser resection resulted in excellent resolution of airway patency with good follow-up results in both cases.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
7/26. Granulocytic sarcoma of the tracheobronchial tree: bronchoscopic and pathologic correlation.Granulocytic sarcoma (GS) is an extramedullary, solid tumor composed of immature granulocytic cells, which occurs in association with myeloproliferative or leukemic disorders. GS can precede, accompany, or complicate the presence of hematologic malignancy in the blood or bone marrow. The anatomic distribution commonly includes bone, nerve, lymph node, and skin, but may involve a variety of soft tissues. Pulmonary involvement is uncommon but may invade the parenchyma, pleura, mediastinum, and airways. We report a rare case of endobronchial granulocytic sarcoma with bronchoscopic and pathologic correlation.- - - - - - - - - - ranking = 4keywords = tree (Clic here for more details about this article) |
8/26. Bronchoscopic Nd-YAG laser surgery for tracheobronchial mucoepidermoid carcinoma--a report of two cases.Mucoepidermoid carcinoma (MEC) of the tracheobronchial tree represents 0.2% of all lung tumours. It arises from the excretory ducts of the bronchial mucosa and is classified into low- and high-grade tumours using criteria derived from similar tumours of the major salivary glands. Low-grade MEC behaves in a benign fashion with less parenchymal and hilar lymph nodal invasion. The traditional method of treatment is by thoracotomy. The bronchoscopic approach to this lesion using lasers has rarely been reported. This article reports two cases of low-grade tracheobronchial MEC, which were both managed through bronchoscopic neodymium yttrium aluminium garnet (Nd-YAG) laser surgery. The patients were free from disease, 26 and 36 months after surgery. Bronchoscopic laser surgery promises to be an effective alternative treatment modality for tracheobronchial MEC. It is minimally invasive, results in less hospital stay and does not impair pulmonary functions.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
9/26. Endobronchial and parenchymal juvenile laryngotracheobronchial papillomatosis. Effect of photodynamic therapy.Juvenile laryngotracheobronchial papillomatosis (JLTBP) is a recurrent, prolonged disease usually confined to the upper airway. Rarely, tracheobronchial tree or lung parenchymal involvement occurs. The various therapeutic interventions are often unsuccessful once extralaryngeal involvement becomes apparent. Photodynamic therapy (PDT) has been successful in eradicating JLTBP in a few case reports. We present a case of extensive JLTBP with parenchymal involvement treated with multiple courses of PDT. We demonstrated temporary regression of endobronchial papillomas, but no change in parenchymal lesions. Recurrent endobronchial disease was most likely related to reinfection from parenchymal lesions inaccessible to PDT.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
10/26. Adenoid cystic carcinoma of the tracheobronchial tree: clinicopathology and immunohistochemistry.Adenoid cystic carcinoma of the tracheobronchial tree in five patients was treated surgically and the clinicopathologic manifestations and histogenesis were examined in detail. Symptoms such as cough, dyspnea, hemoptysis, and atelectasis on chest X-ray were present in four patients, and the other patient was asymptomatic. Histologically, growth patterns were classified as tubular, cribriform, and solid. The solid pattern was the most aggressive with extensive perineural invasion. Immunohistochemically, secretory component, lactoferrin, and epithelial membrane antigen were present in the cells lining the gland-like lumen of tissues with the tubular and cribriform patterns, but was rare in those with a solid pattern. desmin and S-100 protein were detected in the nonlining cells of tissues with all three patterns. These findings suggest that this tumor originates from the myoepithelial cells of the bronchial gland and that the solid pattern was the most poorly differentiated form.- - - - - - - - - - ranking = 5keywords = tree (Clic here for more details about this article) |
