Primary pulmonary paraganglioma: Two cases.

Paraganglioma is a rare tumor originating from extra-adrenal chromaffin cells. Primary pulmonary paraganglioma can also be seen in pediatric patients. Due to its endobronchial localization, morphological features, and neuroendocrine immunohistochemical profile, primary pulmonary paraganglioma can be confused with carcinoid tumor. Primary pulmonary paraganglioma should be considered in the differential diagnosis of endobronchial tumors and necessary precautions should be taken, considering that it may be functioning. In appropriate cases, bronchial sleeve resection provides curative treatment. In this article, we present two cases: First was a functioning primary pulmonary paraganglioma that underwent lobectomy and second was an entirely endobronchial tumor without any extra-bronchial spread that underwent bronchial sleeve resection.
