Primary cervicothoracic thyroid paraganglioma

Primary cervicothoracic thyroid paraganglioma.

A 44-year old man presented with increased shortness of breath. A chest X-ray revealed a widening of the mediastinum (Fig. 1a). Magnetic resonance imaging demonstrated a right paratracheal tumour (Fig. 1b, c). Rotational arteriography showed that the right thyrocervical artery was supplying the mass (Fig. 1d). He underwent a right cervical incision and thoracotomy resection of the mass. Histolo...

Malignant primary pulmonary paraganglioma.

The histological, immunocytochemical, and electron microscopic findings in a case of malignant primary pulmonary paraganglioma are reported. The existence of this rare tumour is evidence for the presence of pulmonary chemoreceptors.

Primary Cardiac Pheochromocytoma (Paraganglioma)

Pheochromocytomas are catecholamine-producing neuroendocrine tumors arise from primitive neural crest cells. About 90% of these tumors occur as solitary benign tumors of the adrenal medulla, where majority of chromaffin cells are concentrated. Only ten percent originates from extra-adrenal sites with the organ of Zukerkandal (paraganglia along abdominal aorta) being the most common. Chromaffin ...

Primary Pulmonary Paraganglioma

Primary pulmonary paraganglioma is a rare disease. We report a case of a 37-year old female patient with space-occupying lesions in the right lower pulmonary lobe during a routine examination without any symptoms. The patient underwent video-assisted thoracoscopic surgery (VATS) resection of the right middle lobe and dissection of hilar and mediastinal lymph nodes under general anesthesia. She ...
