1/15. 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 = hemangioma (Clic here for more details about this article) |
2/15. Endobronchial tumors in children: an uncommon clinical entity.We performed a retrospective chart review of 10 children in whom endobronchial tumors were diagnosed in a tertiary-care children's medical center from 1988 to 1998. Of the 10 patients, 6 were male and 4 were female (8 white, 1 Hispanic, 1 African American). The mean age at presentation was 5.2 years. Eight tumors were benign, and 2 were malignant; 4 were on the right side, 3 were on the left side, and 3 were bilateral. Histologic findings included 3 bronchial papillomas, 3 inflammatory masses, 1 endobronchial hemangioma, 1 leiomyoma, 1 mucoepidermoid carcinoma, and 1 bronchial carcinoid. Endobronchial tumors in children are a rare disorder. The diagnosis requires a high index of suspicion in children with atypical or chronic respiratory complaints. Newer adjuvant medical therapies and surgical innovations offer improved disease control in these patients, and a multidisciplinary approach is often warranted.- - - - - - - - - - ranking = 0.14285714285714keywords = hemangioma (Clic here for more details about this article) |
3/15. Endobronchial juvenile hemangioma--a case report of a neonate including immunohistochemical monitoring and nuclear, cellular, and vascular morphometry.A 3-month-old female child suffered from tachypnea and dyspnea with abnormal blood gas values. Chest x-rays revealed an increased transparency of the left lung and a mediastinal shift to the right side. High resolution computed tomography (CT) documented a narrowing of the left upper stem bronchus. Ensuing endoscopy detected an occlusive endobronchial tumor mass that did not infiltrate the bronchial cartilage as confirmed with endobronchial ultrasonic monitoring. Based on gross histological examination of the surgical specimen obtained using sleeve resection, the highly vascularized tumor exhibited an adenomatoid growth pattern with a rather homogeneous population of nuclei. The light microscopical presentation was consistent with a juvenile (infantile) hemangioma, which was confirmed using immunohistochemical examinations despite the display of neuroendocrine features. Although endobronchial juvenile hemangiomas are an extremely rare event in early childhood, this case underscores the necessity to not neglect its occurrence in differential diagnosis.- - - - - - - - - - ranking = 0.85714285714286keywords = hemangioma (Clic here for more details about this article) |
4/15. Obstructing endobronchial malignant fibrous histiocytoma.A 58-year-old male patient admitted with malignant fibrous histiocytoma of the left mainstem. Rareness and unusual presentation of malignant fibrous histiocytoma and surgical management for lung salvage made its reporting worthwhile. In this localization, prognostic characteristics are better than in the other localizations of lung and body.- - - - - - - - - - ranking = 61.672518788126keywords = histiocytoma (Clic here for more details about this article) |
5/15. Primary racemose hemangioma of the bronchial artery.A 44-year-old woman was admitted to our hospital for repeated hemoptysis. Selective angiography of the bilateral bronchial arteries showed them to be enlarged and convoluted, and revealed shunts between the bronchial and pulmonary arteries. The patient was diagnosed as having racemose hemangioma of the bronchial artery. Although embolization of the bronchial artery with gelatin sponges was performed, hemoptysis emerged again about one year later. Finally, segmentectomy of the right lower lung was performed and primary racemose hemangioma of the bronchial artery was histopathologically confirmed.- - - - - - - - - - ranking = 0.85714285714286keywords = hemangioma (Clic here for more details about this article) |
6/15. Obstructing endobronchial fibrous histiocytoma: potential for lung salvage.In the past 10 years two children, ages 3 1/2 and 7 years, have been seen with central endobronchial fibrous histiocytoma causing complete atelectasis. Each child had a 4- to 6-month history of cough, dyspnea and fever. After antibiotic failure, x-rays demonstrated complete unilateral lung collapse. bronchoscopy in case 1 demonstrated total occlusion of the left mainstem bronchus with 80% stenosis of the right. Left pneumonectomy was ultimately performed with removal of tumor frm the right bronchus. Ten years later the patient is well. Case 2 had an extrinsic etiology ruled out by computed tomography scan. ventilation/perfusion scan showed no ventilation and only faint perfusion of the involved lung. Pulmonary function testing showed moderate to severe restrictive changes with air trapping. Total obliteration of the left mainstem with tumor projecting into the carina was observed on bronchoscopy. Endoscopic resection was not felt to be safe. thoracotomy showed a totally atelectatic, edematous lung filled with pus. The left main bronchus was opened, the tumor removed, and the distal bronchus lavaged and selectively ventilated. Partial lung expansion was obtained. The child is well 1 1/2 years later with a normal chest radiograph, pulmonary function tests, and bronchoscopy. Fibrous histiocytomas of the lung, if in a central endobronchial location, can cause complete lung collapse. A combination of tumor resection, lavage, and selective ventilation should be attempted as an alternative to pneumonectomy, even if the lung appears to be nonsalvageable.- - - - - - - - - - ranking = 61.672518788126keywords = histiocytoma (Clic here for more details about this article) |
7/15. Capillary hemangioma of the right main bronchus treated by sleeve resection in infancy.Respiratory distress developed in a 5-month-old female infant with roentgenographic evidence of hyperinflation of the right lung. bronchoscopy revealed a vascular tumor extending from the medial wall of the right main bronchus leading to a check-valve mechanism. Radionuclide lung scans showed ventilation and perfusion of the right side reduced to 36 and 11% of the total lung ventilation and perfusion, respectively. At the age of 7 months a sleeve of the right main bronchus was resected and a reanastomosis performed. The operation specimen contained a capillary hemangioma measuring 1.2 X 0.6 cm. The postoperative course was uneventful. perfusion of the right lung had markedly improved 6 months after the operation, and at the age of 2 yr and 9 months it was completely normal. Capillary hemangiomas must be considered a cause of bronchial obstruction in infancy, and surgery can be performed successfully.- - - - - - - - - - ranking = 0.85714285714286keywords = hemangioma (Clic here for more details about this article) |
8/15. Inflammatory fibrous histiocytoma of the bronchus.A 33 year-old woman underwent lobectomy of the middle and lower lobes of the right lung because of inflammatory fibrous histiocytoma of the bronchus. To our knowledge, this is the first description of such a tumor originating in the bronchus.- - - - - - - - - - ranking = 51.393765656772keywords = histiocytoma (Clic here for more details about this article) |
9/15. Endobronchial histiocytoma.histiocytoma is an inflammatory pseudotumor usually found in the lung parenchyma or pleura. Endobronchial localisation is rare and can cause atelectasis or air-trapping. Conventional chest X-ray can show the tumor and secondary pulmonary changes. Conventional tomograms and CT can give additional information about tumor extension. However, to make the final diagnosis, biopsy is necessary.- - - - - - - - - - ranking = 41.115012525418keywords = histiocytoma (Clic here for more details about this article) |
10/15. Benign fibrous histiocytoma: a rare endobronchial neoplasm.Fibrous histiocytomas are rarely found within the lung and have presented as a mass within a major airway only twice previously. This is the third reported case of such a tumor visualized roentgenographically in an airway on the frontal chest film of a patient presenting with recurrent pneumonia.- - - - - - - - - - ranking = 51.393765656772keywords = histiocytoma (Clic here for more details about this article) |
