1/12. Granular cell myoblastoma of the cervical trachea.Only five granular cell myoblastomas affecting the cervical trachea have been previously reported. Two of these tumors appear to be primary lesions of the trachea, while the remaining three appear to involve it only secondarily. We report a case of an intraluminal granular cell myoblastoma arising from the right tracheal wall in a 45-year-old woman. The tumor extended into the partition wall between trachea and esophagus. Treatment was by surgical excision of the tumor and the involved tracheal ring. The patient was free of recurrence one year after treatment.- - - - - - - - - - ranking = 1keywords = trachea (Clic here for more details about this article) |
2/12. Pretracheal cervical granular cell myoblastoma.This case report deals with a solitary granular cell myoblastoma extrinsic to the proximal trachea. This lesion can be encountered frequently by the plastic surgeon; its histology, incidence and treatment are reviewed here. It is important to reemphasize that local extirpation is appropriate treatment of what is almost always a benign neoplasm, and intraoperative pathological diagnosis guides the surgeon in providing curative therapy.- - - - - - - - - - ranking = 0.55555555555556keywords = trachea (Clic here for more details about this article) |
3/12. Treatment of tracheobronchial granular cell myoblastomas with endoscopic bipolar cautery.Granular cell myoblastomas of the trachea and right upper lobe bronchus were discovered incidentally during therapeutic bronchoscopy. Because of their propensity to cause airway compromise and distal atelectasis, ablation of both lesions was undertaken. This is the first reported case of bipolar cautery of GCM through a flexible fiberoptic bronchoscope. Small tumor size and lack of atelectasis permitted utilization of this technique. Long-term follow-up is necessary to compare this therapy with other nonresectional therapies.- - - - - - - - - - ranking = 0.11111111111111keywords = trachea (Clic here for more details about this article) |
4/12. Symptomatic solitary granular cell tumor of the trachea.The granular cell tumor is a neoplasm that has generated considerable controversy. A rare case of solitary granular cell tumor located in the cervical trachea is described with a new mode of therapy using the carbon dioxide laser.- - - - - - - - - - ranking = 0.55555555555556keywords = trachea (Clic here for more details about this article) |
5/12. Granular cell myoblastoma: rare localization in the trachea. Report of a case and review of the literature.Granular cell myoblastoma is an uncommon tumor in the respiratory tract. It usually occurs in the tongue, skin, breast, or subcutaneous tissue. When it occurs in the respiratory tract, it is usually located in the bronchus or larynx. Primary tracheal location is rare with only nine such cases reported in the literature. This report describes a 26-year-old woman with granular cell myoblastoma of the trachea. She presented with a four-year history of bronchial asthma. The tumor was surgically excised by tracheal resection and reconstruction. The patient has remained well and free of obstructive airway symptoms, without recurrence of the tumor for more than one year.- - - - - - - - - - ranking = 0.77777777777778keywords = trachea (Clic here for more details about this article) |
6/12. Large granular-cell myoblastoma of the oesophagus.A granular-cell tumour of the oesophagus, the largest hitherto described, was found in a 44-year-old woman. Histologic examination showed an infiltratively growing granular-cell myoblastoma without pleomorphism or mitotic activity. Local extirpation of the tumour was attempted in order to preserve oesophageal continuity. However, a tracheo-oesophageal fistula and stenosis of the previously tumour-bearing area developed and necessitated nasogastric tube feeding for 18 months. Two attempts to close the fistula, including resection of the fistula-bearing tracheal area, failed. Final cure was achieved by subtotal extirpation of the oesophagus and gastro-oesophageal anastomosis in the neck with the stomach placed retrosternally. Normal intake of food was restored after this operation and 30 months later the patient is doing well.- - - - - - - - - - ranking = 0.11111111111111keywords = trachea (Clic here for more details about this article) |
7/12. granular cell tumor of the trachea.Granular cell tumors are rare neoplasms that arise in different regions of the body. Their cell of origin is still debated among many pathologists, but recent authors consider them to be neurogenic. These tumors are believed to be benign; however, local recurrences after excision and multifocality arouse suspicions for malignancy. In the head and neck, granular cell tumors occur most frequently in the tongue. In the laryngotracheobronchial tree, most tumors reported have been in the larynx and the next most in the bronchi. Only six cases of true tracheal occurrences have been reported previously; two additional cases are reported in this paper. The literature of the cell of origin of these tumors is reviewed, the different theories are presented, and diagnosis, treatment, and follow-up are discussed.- - - - - - - - - - ranking = 0.55555555555556keywords = trachea (Clic here for more details about this article) |
8/12. Granular cell myoblastoma involving the recurrent laryngeal nerve.An unusual granular cell myoblastoma occurred surrounding the recurrent laryngeal nerve. Available information regarding the origin, biological behavior, and treatment of such tumors arising from the cervical trachea was reviewed. Frequently, the histologic features cause this lesion to be mistaken for a malignant tumor, and errors in diagnosis and treatment may be made. To our knowledge, encasement of a major motor nerve in the neck by a granular cell neoplasm has never before been reported. Since the overwhelming majority of these tumors behave in a benign fashion, we recommend that the surgeon attempt to spare functionally important nerves in rare instances when they are grossly surrounded by tumor.- - - - - - - - - - ranking = 0.11111111111111keywords = trachea (Clic here for more details about this article) |
9/12. Transbronchoscopic versus surgical resection of tracheobronchial granular cell myoblastomas. Suggested approach based on follow-up of all treated cases.The case of a 31-year-old patient with a granular cell myoblastoma causing significant obstruction of the distal trachea is presented. A review of the literature suggests that size may help in deciding whether bronchoscopic removal or surgical resection should be performed. Fifty-four percent of the tumors removed bronchoscopically whose follow-up was described showed recurrent disease. All tumors removed bronchoscopically whose diameter was 1 cm or greater recurred. The correlation of full-thickness involvement of the tracheal wall with increasing tumor size appears to explain the failure of bronchoscopic treatment of these tumors. A suggested surgical approach to these rare tumors is proposed.- - - - - - - - - - ranking = 0.22222222222222keywords = trachea (Clic here for more details about this article) |
10/12. Granular cell myoblastoma of the bronchus in a child: a case report.Granular cell myoblastoma of of the right main bronchus in a 5-year-old girl is reported. The tumor extended to the lower trachea from the right main bronchus which was occluded completely by the tumor. The diagnosis was established histologically by a obtaining bronchoscopic biopsy specimen. Right pneumonectomy was carried out to control pulmonary suppuration caused by the tumor obstruction of the bronchus. External radiotherapy and interstitial brachytherapy were successful to control the growth of the residual tumor. She has been free from symptoms for about 12 years after the treatment.- - - - - - - - - - ranking = 0.11111111111111keywords = trachea (Clic here for more details about this article) |
