Ganglioneuroma is the most differentiated tumor of neural crest origin and rarely arises in the adrenal gland. Ganglioneuroma is typically known to be benign, but very rarely can metastasize to distant sites. We report a case of a 31-year-old man with a huge adrenal mass with hepatic metastases.

Embryologically, chromaffin cells of the pheochromocytoma and ganglion cells of the ganglioneuroma are both derived from neural crest cells. Composite pheochromocytoma-ganglioneuroma (Pheo-GN) in a single adrenal gland is very rare. A case report of a patient with composite Pheo-GN of the adrenal gland and renal pelvic cancer is presented. Laparoscopic left adrenalectomy, nephroureterectomy and...

Peripheral nerve sheath tumors (PNST) are exceedingly rare, especially outside of the posterior mediastinum. These tumors represent less than 1% of pulmonary tumors. Very few pulmonary PNSTs are ganglioneuromas. We present a case of a ganglioneuroma presenting as an endobronchial mass. CASE PRESENTATION An 80 year old male was seen in pulmonary clinic for routine cancer screening. He had a 60...

INTRODUCTION Ganglioneuroma is a rare tumor in the posterior mediastinum; fat-containing ganglioneuromas are rarely reported. The present case report documents a brown fat-containing, posterior mediastinal ganglioneuroma, which has not been reported previously. Radiological examination, in particular 18F-2-fluoro-2-deoxyglucose-positron emission tomography, suggested that the tumor had low-grad...

A man with gastric cancer presented with a 3-month history of constipation and abdominal pain. Colonoscopy revealed a 9-mm pedunculated polyp in the sigmoid colon (image A), which was then removed. Histopathologic evaluation of the resected polyp (image B) revealed displaced colonic crypts with underlying proliferation of ganglion (white arrows) and spindled Schwann cells (black arrows) within ...

BACKGROUND Paragangliomas occur most commonly in head and neck region and much less frequently, they are found in the retroperitoneum. Composite paraganglioma-ganglioneuroma of the retroperitoneum is very rare. CASE PRESENTATION We present an unusual case of retroperitoneal composite paraganglioma-ganglioneuroma discovered on computed tomography in a 63-year-old female patient. Routine hemato...
