Tracheal paraganglioma

Paragangliomas are tumours originating from the autonomic nervous system and rarely occur in the chest. They may manifest through symptoms of excess catecholamine release or due to local compression, can be an incidental finding on a computed tomography/magnetic resonance imaging examination or can be found when screening patients with specific gene mutations. Surgical removal is indicated in case of symptoms, (imminent) compression of vital structures or to prevent progression to malignancy. Resection of a paraganglioma in the middle mediastinum can be challenging...

The describes a clinical observation of a combination of jugulotympanic paraganglioma of the left temporal bone with multifocal congenital hemangioma. The interest of the case is that such a combination of pathologies is extremely rare. A comprehensive study and surgical treatment of a patient with this clinical diagnosis was carried out. In the diagnosis, objective otorhinolaryngological studies, otomicroscopy and MSCT of the temporal bones and MRI of the middle ear with contrast were used. Surgical intervention was performed under multicomponent anesthesia with tracheal intubation, transmastoid access...

Primary paraganglioma of the trachea is a rare differential among more common tracheal masses. Definitive diagnosis of tracheal masses is obtained via endoscopic biopsy. Utilization of 68Ga-DOTATATE PET/CT is valuable in the workup of these lesions as paragangliomas would have significantly higher radiotracer uptake compared with the more common squamous cell and adenoid cystic carcinomas. This is particularly important in tracheal paragangliomas, which are typically friable and hypervascular with higher risk of significant bleeding on biopsy...

BACKGROUND: Subglottic paragangliomas (PGs) are exceptionally rare and unpredictable, occasionally presenting at an atypical location. There are three different clinical forms of subglottic PGs: intraluminal (tracheal PGs), extraluminal (thyroid PGs) and the mixed type (both intraluminal and extraluminal, mixed-subglottic PGs). These tumors are usually misdiagnosed as other relatively common primary thyroid or laryngotracheal tumors, and the treatment is troublesome. CASE PRESENTATION: A 22-year-old male patient with subglottic PGs has been successively misdiagnosed as thyroid tumors and subglottic hemangiomas, and lastly underwent local extended lumpectomy and laryngotracheal reconstruction with a pedicled thoracoacromial artery perforator flap (PTAPF)...

The trachea is a sporadic origin of paraganglioma. The purpose of the present study was to identify the features of tracheal paraganglioma and reveal the effectiveness of computed tomography (CT) and magnetic resonance imaging (MRI) by reviewing both previous and current cases. In cases of tracheal tumors, we need to consider the bleeding risk associated with a biopsy, as the tumor may be paraganglioma, which is hypervascular. If a biopsy is not available, then CT and MRI can aid in making a pre-operative diagnosis...

In recent years, parenchymal sparing techniques for tumor resection have been developed in order to reduce the amount of lung parenchyma that must be removed in cases of centrally located tumors. These techniques maintain oncological radicality while reducing postoperative complications. At the same time, video-assisted thoracoscopic surgery (VATS) has been shown to offer comparable surgical and oncological outcomes to thoracotomy, even in complex cases that require tracheal and bronchial reconstructions. In this video tutorial, we describe a case of an isolated sleeve resection of the bronchus intermedius performed through a VATS approach for a bronchial paraganglioma...

INTRODUCTION: Paraganglioma is a rare neuroendocrine tumor and may sometimes be located in the membranous part of the trachea. PRESENTATION OF CASE: We report the case of a 52-year-old man presenting a paraganglioma just above the carina with obstructive symptoms. The patient successfully underwent a non-circumferential tracheal membranous resection, followed by latissimus dorsi muscle flap repair, under peripheral extra-corporeal membrane oxygenation (ECMO). DISCUSSION: Complex carinal resection can be avoided for tracheal membranous tumors and replaced with non-circumferential resection and direct reconstruction with a muscle flap...

Ectopic thyroid gland is a developmental anomaly that results from the arrest of thyroid tissue along its path of descent from the floor of mouth to the pre tracheal position in the lower neck. It is typically found along the thyroglossal duct with the base of the tongue being the most common site. Apart from mediastinal extension of goiter, the incidence of true intrathoracic ectopic thyroid tissue is rare. Presence of ectopic thyroid has been reported not only in the chest but also in the abdomen and pelvis...

OBJECTIVE: To review tracheal paragangliomas and describe the clinical presentation, radiologic findings, operative management, and histologic findings of a pediatric patient who presented with stridor refractory to traditional asthma therapy. METHODS: Chart review of an 8-year-old male who presented to a tertiary care pediatric hospital and literature review of tracheal paragangliomas. RESULTS: We present the case of an 8-year-old male who presented with new-onset of wheezing and dyspnea on exertion...

INTRODUCTION: Thyroid paraganglioma is a very rare malignant neuroendocrine tumor. Immunohistochemical features of thyroid paraganglioma are helpful for the diagnosis. CASE REPORT: A 69-year-old female came to hospital with the presence of a growing thyroid nodule of the left lobe. Ultrasonic neck examination showed 5 cm hypoechoic nodule in the left thyroid lobe. Thyroid scintigraphy showed a big cold nodule in the left lobe. Computed tomography (CT) scan showed left lobe thyroid tumor with tracheal deviation on the right site...

Glomus tumors are uncommon soft tissue tumors that usually occur in the hands or feet but rarely have been described to appear in the tracheobronchial tree. Tracheal glomus tumors present with symptoms including cough, dyspnea, and wheezing that may be mistaken for other pulmonary disorders. Imaging and pulmonary function testing can detect tracheal obstruction, but pathology is necessary to differentiate glomus tumors from other airway tumors. On pathology, glomus tumors are made up of glomus cells, blood vessels, and smooth muscle and are classified based on the predominant cell type...

The purpose of this article is to review the computed tomography (CT) and histopathological features of uncommon primary neoplasms of the thorax that can manifest clinically malignant features (multiplicity of pulmonary nodules, an invasive nature, and metastases or recurrence after surgery) with little evidence of histological malignancy.

Paraganglioma of the trachea is a rare neoplasm, with fewer than 15 cases reported. A 40-year-old man presented with stridor and hemoptysis. Bronchoscopy demonstrated a tumor of the posterior trachea and biopsy initially suggested typical carcinoid. The patient underwent surgical resection uneventfully and made a good recovery. Final pathology disclosed the tumor to be a paraganglioma based on immunohistology. The pathophysiology and treatment of this tumor are discussed.

AIM: We report on nine highly selected patients in whom the resection of the tumor was only possible with cardiopulmonary bypass (CPB). METHODS: Between November 1996 and November 2009, nine patients with non-cardiac tumors underwent surgery under CPB. Indications were: infiltration of the pulmonary vein in the left atrium (four cases), one case where the tumor (a paraganglioma apparently located in the subcarinal space) was actually in the atrium wall, one mediastinal liposarcoma with massive infiltration of the pericardium and the main pulmonary artery, and three tracheal tumors (2 cylindromas and 1 carcinoid)...

BACKGROUND: Thyroid paraganglioma (TP) is a very rare neoplasm that can be misdiagnosed. We evaluated the clinical and pathologic characteristics of three patients with TP. PATIENT FINDINGS: The records of all patients from 1981 to 2008 who had thyroidectomy with a final histologic diagnosis of TP were retrieved, and histology was reviewed by a single pathologist. Head and neck paragangliomas arising outside of the thyroid were excluded. TP accounted for 3 of all 6782 (0...

Paragangliomas are neuroendocrine tumors that originate from extra-adrenal chromaffin cells. The trachea is an unusual site for paragangliomas. A 29-years-old female was admitted to our clinic with complaints of recurrent hemoptysis and dyspnea, and a 1.5x1.3 cm mass in the posterior wall of the trachea, which was subsequently diagnosed as a paraganglioma. In this report, we presented the 11th case of tracheal paraganglioma, a rare benign tracheal tumor, and reviewed the medical literature.

36 patients were operated on lung cancer (30), trachea (1), lung colon cancer metastases (1), left atrium paraganglioma, bronchogenic thymic cyst (1) and lung tuberculoma (2). Competing cardio-vascular diseases were as follows: coronary heart disease (30), valve failure (3) and critical stenosis of internal carotid artery (3). Simultaneous operations were performed in 13 (36.1%), consecutive - in 23 patients. Non-complicated postoperative period was registered in 19 patients. 6 of them had simultaneous surgery and 13 were operated on consecutively...

Paraganglioma with tracheal location is a rare tumor. Twelve cases with involvement of the trachea have been reported in English literature, including six cases of solely tracheal paragangliomas. We present a case of a paraganglioma confined to the tracheal wall in a 33-year-old pregnant woman. The tumor was locally resected. Follow-up 17 months later showed no evidence of relapse. Based on the literature, we found that the most common symptoms are respiratory impairment and haemoptysis. None of the cases showed malignant behaviour...
