1/21. Malignant fibrous histiocytoma of the trachea.Primary tracheal sarcomas are rare. Only 23 cases have previously been reported in the English literature. The present case describes a 72-year-old woman with a malignant fibrous histiocytoma of the trachea. She underwent an endoscopic resection followed by radiotherapy and is well at 12 months follow up. Other cases are reviewed. Tracheal resection is the standard care. However, local resection with postoperative radiotherapy remains an option. Adjuvant chemotherapy may improve local control. Long-term survival has been documented.- - - - - - - - - - ranking = 1keywords = histiocytoma (Clic here for more details about this article) |
2/21. 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 = 0.0012147031574456keywords = hemangioma (Clic here for more details about this article) |
3/21. Benign fibrous histiocytoma of the trachea.Benign fibrous histiocytoma of the trachea is a rare neoplasm. We reported 2 cases, one aged 3 years and one 5 years, with endotracheal fibrous histiocytoma showing no clinical evidence of malignancy. Two segments of the trachea were resected and an end-to-end anastomosis was done in 1 case and circular resection of the left bronchi and carinoplasty for the other. Pathologically, both tumors consisted of spindle cells arranged in storiform and fascicular patterns. Immunohistochemically, tumor cells stained for vimentin and CD68 but were negative for P53. These cellular features and immunohistochemical findings indicate benign fibrous histiocytoma of the trachea. No recurrence was seen.- - - - - - - - - - ranking = 1.4keywords = histiocytoma (Clic here for more details about this article) |
4/21. 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 = 0.0010411741349533keywords = hemangioma (Clic here for more details about this article) |
5/21. Juvenile hemangiomas involving the thoracic trachea in children: report of two cases.Two 3-month-old girls presented with posterior mediastinal juvenile hemangioma (JH), a benign tumor rarely found in the mediastinum. Incomplete resections were performed. Over 4 and 7 months, respectively, the hemangiomas recurred and grew through the tracheal wall into the tracheal lumina, reducing the airway by 90% in one case and 70% in the other. The recurrences were resected, including five tracheal rings in the first case and four in the second. In case 1 the tumor recurred in the trachea 2 months later. A tracheostomy was performed, and corticosteroids were administered for 6 months. The tumor involuted and the patient was decannulated after 18 months; she is doing well 7 years later. The patient in case 2 has been well in the 18 months since her second operation. Airway obstructions can be treated by tracheal resection when conservative management fails.- - - - - - - - - - ranking = 0.0010411741349533keywords = hemangioma (Clic here for more details about this article) |
6/21. Six cases of children with a benign cervical tumor who required tracheostomy.Cervical tumors sometimes cause airway obstruction. We have treated six children with benign cervical tumors who required tracheostomy. Two cervical and one glossal lymphangiomata treated with local injection of OK432 after creating a tracheostomy were successfully decannulated after the treatment. One patient with a giant cervical lymphangioma needed an EXIT (ex utero intrapartum treatment) procedure. He underwent tracheostomy at 10 months of age after long-term endotracheal intubation, but he died of sepsis and hypoxic brain damage at 18 months. One patient with a subglottic hemangioma treated with steroids finally achieved closure of the tracheostomy at 2 years of age. A 7-year-old girl with a tracheal schwannoma underwent tracheostomy performed a week after admission, but she already had hypoxic brain damage resulting from problems with intubation. Most patients with a lymphangioma or hemangioma in the cervical region have required early tracheostomy before commencing treatment with OK-432 or steroids. If there is any sign of possible airway compromise, then it is vital to perform an early tracheostomy, even for benign tumors.- - - - - - - - - - ranking = 0.00034705804498445keywords = hemangioma (Clic here for more details about this article) |
7/21. association of solitary, segmental hemangiomas of the skin with visceral hemangiomatosis.BACKGROUND: Multiple hemangiomas of the skin have traditionally been recognized as a clue to potential visceral hemangiomas. Recently, hemangiomas have been recognized to have subcategories, localized and segmental, which correlate with risk of complications. While less common, segmental hemangiomas of the skin have a higher risk of being life- or function-threatening and/or having associated structural anomalies such as those that occur in PHACE (posterior fossa brain malformations, hemangiomas, arterial anomalies, coarctation of the aorta and cardiac defects, and eye abnormalities) syndrome (PHACES, if sternal clefting/supraumbilical raphe is included). However, the potential association of solitary, segmental hemangiomas of the skin with visceral hemangiomatosis has not been previously emphasized. OBSERVATIONS: A total of 47 cases of segmental hemangiomas of the skin in association with visceral hemangiomatosis were found. The location of the cutaneous hemangiomas most commonly, but not exclusively, involved the face (37 cases [79%]). The most common site of internal organ involvement was the liver (20 cases [43%]), followed by the gastrointestinal tract (16 [34%]), brain (16 [34%]), mediastinum (9 [19%]), and lung (7 [15%]). The percentages of reported cases of hemangiomas of the pancreas, spleen, bones, or kidneys were 6% or less. Forty percent of patients met criteria for the diagnosis of PHACE(S) syndrome. In this subgroup, internal organ hemangiomas were most commonly found in the brain or mediastinum (18 cases [53%]). overall, 12 patients (25%) died during infancy, most commonly because of gastrointestinal involvement or congestive heart failure secondary to liver involvement.Conclusion Segmental hemangiomas of the skin have an associated risk of visceral hemangiomatosis, with the potential of causing vital organ compromise.- - - - - - - - - - ranking = 0.0038176384948289keywords = hemangioma (Clic here for more details about this article) |
8/21. Malignant fibrous histiocytoma of the trachea.We experienced a rare case of malignant fibrous histiocytoma (MFH) arising in the trachea. A 24-year-old man with severe dyspnea had a well-defined mass in the cervical trachea on chest X-ray examination. Chest computed tomography showed a 2.0-cm diameter mass originating in the right-posterior wall of the trachea. The tumor occupied over 90% of the lumen. A radical excision of the tumor (tracheal resection) with tracheal plasty was performed. The microscopic diagnosis was MFH. The patient remains well, without evidence of recurrence, 3 months after surgery.- - - - - - - - - - ranking = 1keywords = histiocytoma (Clic here for more details about this article) |
