Gross processing

Benign conditions

Applicable in bleeding disorders, pain, leiomyoma and endometrial hyperplasia.[1]

Gross examination

For orientation:

  • The round ligament lies anterior to the tubes and ovaries.[1]
  • The peritoneum extends further down along the cervix posteriorly than anteriorly.[2] Its ends bluntly posteriorly and sharply anteriorly.[2]

Optionally, remove the adnexa.[1]


  • Perform a general inspection
  • Measure length, width, thickness
  • The uterus is usually opened at the front in the midline, optionally with an incision towards each corner.[notes 2] Open the cavity completely, along the existing incision. The cavity is sometimes be squeezed or rolled around a leiomyoma, and you'll you have to improvise and perhaps go around the leiomyoma to open the cavity properly. Cut through the front wall into both corners.
  • Inspect the mucosa. If any polyps, see Endometrial polyp
  • Measure the thickness of the mucosa and myometrium
  • Inspect the myometrium. If any tumor, see Smooth muscle tumor

Gross report


  • Shape of uterus and adnex
  • Measurements
  • Mucosa, such as smooth or irregular.
  • Any polyps. Further information: Endometrial polyp
  • Mucosal and endometrial thickness
  • Any smooth muscle tumor. Further information: Smooth muscle tumor

=Slices for microscopy


  • Four cross-sectiosn from any accompanying ectocervix. In subtotal extirpation, a cross-section is taken from the lower resection border.
  • A transverse slice through the endocervix, possibly divided into two.
  • One slice from the front and one from the back wall of the corpus, and one piece from each corner, including myometrium.
  • Any mucosal parts with macroscopically abnormal appearance, including polyps.
  • In case of endometrial hyperplasia, most of the mucosa of the corpus and fundus.
  • Samples form all smooth muscle tumors >5 cm in diameter. Further information: Smooth muscle tumor

  2. The uterus can also be opened laterally, through the parameters.
