First Course of Treatment/Surgery of Primary Site--Corpus uteri: Do you code total hysterectomy or radical hysterectomy when a specimen indicates the uterus, cervix, ovaries, fallopian tubes, and right and left parametrium were resected, but shows no portion of the vagina. See Discussion.
AFS1-AFS2-frozen section control, endomyometrium; AFS3-frozen section control, subserosal intramural mass; A4-anterior cervix; A5-posterior cervix; A6-anterior cervical endometrial junction; A7-posterior cervical endometrial junction; A8-A10-anterior endomyometrium, including tumor; A11-A13-posterior endomyometrium, including tumor and adjacent mass; A14-random section subserosal mass; A15-left parametrium at margin of resection; A16-right parametrium at margin of resection; A17-A18-left ovary and fallopian tube; A19-A20-right ovary and fallopian tube. The final diagnosis includes Endometrial adenocarcinoma, favor serous carcinoma, with papillary and solid areas.
