Abstract:
Extra-adrenal pheochromocytomas (paragangliomas) are neuroendocrine tumors derived from extra-adrenal chromaffin cells. Although laparoscopic resection of adrenal pheochromocytomas is a common procedure, there are few reports of the use of this approach in extra-adrenal para-aortic paragangliomas. Here, we report the case of a patient with a subclinical functioning para-aortic paraganglioma that was successfully resected laparoscopically. Case presentation: A 58-year-old man was referred to our department for treatment of a para-aortic tumor after endoscopic submucosal dissection of early-stage colorectal cancer. Positron emission tomography-computed tomography showed abnormal accumulation by the para-aortic tumor. During its laparoscopic resection, the patient's blood pressure unexpectedly rose to over 180 mmHg, which suggested that the tumor was a paraganglioma. The diagnosis was confirmed by immunohistochemical staining, which showed chromogranin-positive cells forming a Zellballen pattern. The operation was successfully completed, and the patient's postoperative course was uneventful. Conclusion: Laparoscopic resection may be a suitable procedure for the treatment of retroperitoneal paraganglioma.
