ABSTRACT A paraganglioma is a rare tumor that develops out of extra-adrenal chromaffin cells and pheochromocytomas originating from the adrenal medulla. Early diagnosis and surgical planning are crucial, since the tumor secretes catecholamine and is adjacent to large vessels in the abdomen. Furthermore, since complete resection improves the prognosis, we recommend a meticulous surgical technique. Here, we present a case of paraganglioma in a 32-year-old male patient who initially presented with a stomachache. After conducting the required tests, we resected the tumor that was pressing against the vena cava in the interaortocaval region.

    ABSTRACT: Paragangliomas are extra-adrenal chromaffin tumors that arise from neuroectodermal cells of the autonomous nervous system. It is difficult to make an accurate preoperative clinical diagnosis of silent paraganglioma. The best choice of treatment is complete surgical resection. However, it is important to note that in patients with functional paragangliomas, the tumor's ability to produce catecholamines may cause abrupt changes in blood pressure. Thus, surgery may induce life-threatening complications. In the present study, we present a case of functional retroperitoneal multiple paraganglioma in a 39-year-old male patient who was diagnosed during surgery. Four years after the operation, the patient remains asymptomatic and free of disease.
