Retroperitoneal paragangliomas: natural history and review of the literature.
Retroperitoneal paragangliomas are uncommon neoplasms that arise from neural crest cells. Typical retroperitoneal sites of origin include adrenal medulla, organs of Zuckerkandl, and along sympathetic and parasympathetic nerves. We present a case of a woman diagnosed with retroperitoneal paraganglioma treated with debulking, intraoperative radiotherapy and external beam radiation therapy. She experienced a 7-year disease-free interval prior to symptomatic metastatic recurrence. Such remissions are consistent with the natural history for paragangliomas. The purpose of this report and literature review is to summarize the pertinent biologic and therapeutic options for these uncommon tumors.
