Key result
Surgical resection provides definitive diagnosis and successful treatment of a rare primary pulmonary paraganglioma.
Why the study?
Primary paraganglioma of the lung is a rare tumor with few reported cases, and the solitary form is particularly uncommon.
Case Report (n=1)
No
This case report describes a rare instance of primary pulmonary paraganglioma treated surgically, highlighting the necessity of histopathological evaluation for definitive diagnosis.
Supports histopathology for atypical pulmonary nodules; extends sparse case literature but leaves management standardization open.
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.

Fiorentino et al. (2015) conducted a case report in Primary pulmonary paraganglioma (n=1). Surgical resection was evaluated on Patient outcome after surgery. Surgical resection and histopathological evaluation of a solitary pulmonary nodule in a 63-year-old man led to the definitive diagnosis and successful treatment of a rare primary pulmonary paraganglioma.
