Introduction: Anastomosing hemangioma in the adrenal area is extremely rare. We report a large anastomosing hemangioma in the adrenal area that underwent robotassisted adrenalectomy. Case presentation: A 49-year-old man with left back pain underwent magnetic resonance imaging (MRI) that revealed a tumor in the left adrenal area; it was diagnosed as nonfunctional endocrinologically. However, the major axis of the tumor increased from 64 to 72 mm during the 4-month period. Robot-assisted left adrenalectomy was performed. Although the large tumor adhered to the surrounding tissues, it was safely resected by the effective use of an extra robotic arm. An anastomosing hemangioma was diagnosed since there were no malignant findings. Conclusion: Robotic surgical systems may serve as an effective treatment option for large adrenal tumors, and our report is the first robot-assisted adrenalectomy performed on an anastomosing hemangioma.

A 67‐year‐old man presented with lower limb weakness, palpitations, and insomnia. His urinary total metanephrine and normetanephrine levels were high. Computed tomography showed a 48 × 34‐mm oval mass on the dorsal side of the pancreas and portal vein between the aorta and vena cava. Because of the tumor location, we performed laparoscopic surgery using a retroperitoneal approach. We described a case of a patient with primary retroperitoneal paraganglioma between the aorta and vena cava who underwent retroperitoneoscopic resection. Our case suggests that this procedure can be safely performed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
