Two cases of pelvic schwannomas simultaneously resected with the prostate by robot‐assisted surgery

Abstract

Schwannoma is a rare benign tumor of peripheral nerves arising from Schwann cells of the ubiquitous nerve sheath. The operative steps and technical aspects of robotic resection of pelvic schwannoma are described herein. Case presentation: We describe two patients with pelvic tumors simultaneously resected with the prostate by robot-assisted surgery: a 69-year-old man with schwannoma of the right side of the pelvic floor and a 68-year-old man with schwannoma in the left pelvis. As metastasis of prostate cancer could not be ruled out, tumorectomy was performed using robotic-associated prostatectomy. Malignancy was absent in the two pelvic tumors, and the patients were diagnosed with schwannoma. Conclusion: For surgery in a narrow deep pelvis, robot-assisted surgery is minimally invasive, offers excellent mobility of robotic instruments and visibility of threedimensional view, and is a useful approach.

Robotic-Assisted Resection of a Benign Schwannoma of the Obturator Nerve: A Rare Case

“…Imaging tests can detect a solid mass lesion that is well defined [ 14 ]. MRI usually shows low to intermediate signal intensity in T1-weighted images and high signal intensity in T2-weighted images [ 15 ], but these changes are not specific [ 16 ]. Although schwannomas are rare, these tumors should be considered in the differential diagnosis of pelvic tumors [ 17 ].…”
