Symplastic glomus tumor of the urinary bladder treated by robot-assisted partial cystectomy: a case report and literature review

Glomus tumors arising in the urinary bladder are extremely rare, and only two cases have been reported in the English Literature. We present a case of a 58-year-old man with an asymptomatic mass of the anterior wall of the bladder that measured 2.5 × 2.5 cm. Endoscopic excision was performed, and the tumor was diagnosed as symplastic glomus tumor. The patient finally underwent robotic-assisted partial cystectomy, and he remains healthy without any recurrence to date.After reviewing this case and previous reports, we analyzed the clinicopathologic features and treatment options for this rare neoplasm.
