ABSTRACT

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 chest revealed a rounded, high-density lesion with irregular profiles measuring 24mm in diameter in the middle lobe. The lesion was suggestive of malignancy. Fine-needle aspiration cytology was performed. The results of the cytological tests were positive for malignant cells. Surgical resection was the choice of treatment. The results of the biochemical tests and postoperative histological examination allowed a definitive diagnosis: primary pulmonary paraganglioma.

Conclusions: Paragangliomas are identified and characterized with the use of computed tomography and other imaging methods, but for a definitive diagnosis, histopathological evaluation is necessary. We report a rare case of a primary pulmonary paraganglioma that was treated surgically. This case report adds valuable knowledge to the literature on pulmonary paragangliomas.

Mentions: We report the case of a 63-year-old Caucasian man who presented with cough, intermittent palpitations and dyspnea. Our patient had a history of smoking. His blood pressure was normal, as were the results of clinical laboratory examinations. Our patient was subjected to a respiratory functional study that showed a moderate, nonreversible obstructive syndrome (forced expiratory volume in the first second (FEV1) 58%); arterial blood gas analysis showed normal oxygen saturation. A chest X-ray showed a lesion in the right lung field (Fig. 1a).Fig. 1
