Malignant primary pulmonary paraganglioma.

Primary paraganglioma of the lung: a case report

INTRODUCTION Primary paraganglioma of the lung is a rare tumor of which few cases are reported in literature. Both solitary and diffuse primary pulmonary paragangliomas are described. The solitary form of this tumor is rare. CASE PRESENTATION We report the case of a 63-year-old Caucasian man with cough, intermittent palpitations and dyspnea. A contrast-enhanced computed tomography scan of his...

پاراگانگلیوم بدخیم(گزارش 1 مورد)

Paraganglioma are tumors that arise within the sympathetic and parasympathetic nervous system. About 10% of paraganglioma spread to distant sites. Malignant potential has been difficult to be determined by histologic characteristic and it is defined after a metastatic lesion or direct invasion found in a site with no residual embryonic paraganglionic tissue. In this case report, a 5...

Pulmonary Paraganglioma Manifesting as an Endobronchial Mass

Thoracic paragangliomas comprise only 1-2% of all paragangliomas, including the adrenal pheochromocytomas, and these tumors are mostly found in the mediastinal compartments (1). To the best of our knowledge, there is only one case report in the pathology literature of endobronchial involvement by a primary pulmonary paraganglioma (2). We report here on the CT and bronchoscopic findings of a cas...

Letter to the Editors Primary Pulmonary Paraganglioma: Case Report and Literature Review

Malignant paraganglioma arising from the posterior mediastinum: a case report and review of the literature.

An unusual case of paraganglioma of posterior mediastinum occurred in a young adult with local recurrence and multiple distant metastasis. Because of its rarity, the determinants of prognosis factor between benign and malignant paraganglioma are uncertain. In this case, we investigated abnormalities of the p53 gene and ras gene mutations in tissues of primary and metastatic lesions. Neither abn...
