[The retropubic ganglion as a rare tumour entity in the lesser pelvis: case report and literature survey].

Retropubic tumours without contact to bones or surrounding tissues are extremely rare with only 22 cases being reported in the literature. The majority of tumours described within these reports are osteochondromas in 17 cases, 2 cases of leiomyoma and one case of each fibroma, fibrosarcoma and nodular fasciitis. We now report the case of a 52-year-old-man with a retropubic ganglion cyst, which was resected "in toto" by laparoscopy.
