Paraganglionic pheochromocytoma, rare retroperitoneal tumor

Abstract

Introduction: Retroperitoneal paraganglionic retroperitoneal pheochromocytoma is a tumor with a biologically benign tendency, although it can be confused with a malignant one; moreover, it causes compression of structures and frequently elevates blood pressure. Objective: To present a patient with a retroperitoneal paraganglionic pheochromocytoma. Clinical case: A 33-year-old female patient with a history of hypertension and epilepsy, both controlled. She came to the hospital because of pain in the right hemiabdomen. Imaging findings suggested a retroperitoneal tumor. Extirpation and biopsy were decided for definitive diagnosis, and surgery was performed without complications. It was concluded as a retroperitoneal paraganglionic retroperitoneal pheochromocytoma. Conclusions: Retroperitoneal paraganglionic retroperitoneal pheochromocytoma is a very rare tumor. The differential diagnosis of any adrenal tumor depends on a thorough interrogation and physical examination, as well as the indication of appropriate diagnostic tools.
