Prior to the publication, in February, 1913, of reports of Cuthbert Lockyer's cases of adenomyoma of the rectovaginal septum,1 the occurrence of such growths in this region had apparently not been observed either by surgeons or by pathologists.
During the month of January, 1913, during which month Lockyer reported his cases, there were sent to me for diagnosis two rectovaginal tumors in which complete hysterectomy had been done. These proved to be counterparts of Lockyer's cases. It is through the courtesy of Dr. William S. Bainbridge, who operated on the patients, that I have the opportunity of reporting the cases.
