Several years ago Greensfelder and one of us (Dr. Bettman) reported a case of retroperitoneal lipoma1 and reviewed the literature to that date. We found that von Wahlendorf2 had collected 166 cases of retroperitoneal lipoma, and that at about the same time Lecéne3 had reported 113 cases of solid paranephric tumors of which many were lipomas. Besides the cases of these two authors we were able to collect 16 other cases: Masson and Horgan,4 12 cases; Holmes,5 1 case; Hirsch and Wells,6 1 case of their own and 1 case of McConnell's,7 and Heppner,8 1 case. Most of these cases had been published after von Wahlendorf's article went to press. At this time we wish to present another case of our own and to review briefly 11 cases that have appeared in the literature since the publication of our last article.
