Nonfunctional Retroperitoneal Paraganglioma: A Histopathological Surprise

Nonfunctional Retroperitoneal Paraganglioma: A Histopathological Surprise

Paragangliomas are the tumors arising from chromaffin tissue which is distributed along the autonomic nervous system. Most of these tumors secrete and store catecholamines. They can be suspected by clinical symptoms and confirmed by biochemical tests. Retroperitoneal paraganglioma mostly arise from adrenal medulla and are also known as adrenal pheochromocytoma. About 10% of abdominal paragangli...

Familial malignant retroperitoneal paraganglioma.

Paragangliomas are neuroendocrine tumours and those occurring in the head and neck have well recognized familial association. Retroperitoneal paragangliomas are uncommon and we present two cases of familial malignant retroperitoneal paraganglioma. Review of the literature revealed marked differences in the incidence and malignant potential of familial and non-familial paraganglioma. In contrast...

Incidental Diagnosis of Nonfunctional Bladder Paraganglioma

Nonfunctional bladder paragangliomas may present clinical, radiology and pathological features similar to bladder cancer, so knowledge of this generally benign neuroendocrine neoplasm is of great importance to avoid misdiagnosis. We present the case of a patient with no clinical symptoms of paraganglioma and with radiological and cystoscopy examination results suggestive of urothelial carcinoma...

Retroperitoneal non-functioning paraganglioma: A case report

Case note: retroperitoneal nonfunctioning paraganglioma.

Paragangliomas are extra-adrenal chromaffin tumours that develop at the expense of neuroectodermal cells of the autonomous nervous system. Retroperitoneal and nonfunctioning forms are very rare. They are often asymptomatic and can reach a substantial size. Treatment usually involves surgery with the goal of total excision. We report the case of a patient who presented with indistinct abdominal ...
