A. K., a woman, aged 46, was admitted to the surgical service of Dr. J. C. Kelly because of tenderness in the right lower quadrant, dysmenorrhea and menorrhagia, all of one year's duration. The past history and the family history were negative. The physical examination was negative except for the pelvis. Bimanual examination revealed an enlarged, tender uterus with a soft mass in the lower right quadrant. This mass was evidently attached to the uterus. There was a moderate, thin, blood stained vaginal discharge.
At operation the uterus was found to contain a large, rounded, soft tumor mass. The adnexa were essentially normal. An amputation was done, and when the uterine wall was cut through above the cervix, masses of tumor tissue were encountered in the myometrium. At some distance in the right broad ligament, vessels were found containing a like tumor mass. The whole material was sent to the laboratory
