INTRODUCTIONAlthough the retroperitoneum and abdominal wall are the most common sites of origin for soft tissue sarcomas (STS) of the abdomen and pelvis, many sarcomas either arise entirely within the extra‐peritoneal pelvis, or cross the parietal peritoneum to enter this space. Probably owing to the fact that so many retroperitoneal sarcomas (RPS) extend into the pelvis (and vice versa), few authors attempt to anatomically define the exact percentages of STS that occur in the pelvis. Indeed, the anatomic site of origin of an abdominopelvic STS is not considered a variable in estimating outcomes in RPS nomograms. However, the rare study that does attempt to distinguish pelvis STS from RPS confirms that approximately 18% of all abdominopelvic sarcomas arise in the pelvis.Given the narrow confines of the bony pelvis, especially in males, and the sometimes‐aggressive nature of soft tissue sarcomas, it can be challenging to safely resect tumors in this location with adequate margins. Soft tissue sarcomas in this area frequently insinuate along or frankly invade through normal anatomic planes. Whether one considers oneself an apostle of the more aggressive, compartmental surgical approach to RPS or the more conservative, histology‐driven, organ‐ and function‐preserving surgical approach, an understanding of the anatomy
