Robot-assisted laparoscopic removal of extraluminal leiomyoma confused with urachal cyst.

Pedunculated extra-luminal leiomyoma is a rare solid tumor. We present a case of a 20-year-old Caucasian woman with a painful pedunculated extraluminal mass located on the bladder dome and associated with dysuria. She underwent robot-assisted laparoscopic resection, and the histological findings confirmed a leiomyoma.
