The uterus is essential for survival of the species. It is commonly afflicted with tumours.

Endometrium and its pathology is dealt with in the endometrium, endometrial hyperplasia and endometrial carcinoma articles.

Other tumours are dealt with in uterine tumours.

Operations

  • Myomectomy.
  • Subtotal hysterectomy.
    • Discouraged... as the cervix remains and can develop a cancer.
  • Total hysterectomy.
  • Radical hysterectomy - total hysterectomy + parametrial tissue.[1]
    • Indications: cervical cancers, advanced uterine cancers.
      • This is typically done by gynecologists with additional training at larger centres.
      • Usually done with a bilateral salpingo-opherectomy (both tubes and ovaries) and pelvic lymph node dissection.

Notes:

  • There are almost no quality of life differences between total & subtotal hysterectomy.[2]

Tumours of the corpus

The most common is leiomyoma (uterine fibroids).

Endometrium

Dealt with in endometrium, endometrial hyperplasia and endometrial carcinoma articles.

Specific conditions

Congenital absence

  • Often in association with vaginal absence; ergo congenital absence of the uterus and vagina (CAUV).
    • AKA Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome.[3]

Features:[3]

  • Subdivided - as etiologies differ.
  • Thought to have a genetic component - autosomal dominant with variable penetration.

Treatment:

  • Uterine transplant - attempted.[4]

Uterine adenomyosis

General

Microscopic

Features:

  • Endometrial glands within uterine muscle - key feature.
    • Endometrial glands:
      • Circular.
      • Simple epithelial or pseudostratified epithelium +/- mitoses.
    • +/-Surrounded by endometrial stroma.
    • Blood:
      • Within glands.
      • Hemosiderin-laden macrophages.

Note:

DDx:

Uterine prolapse

General

  • Clinical diagnosis.
  • A common indication for a total hysterectomy.
  • Hysterectomy specimen usually comes with some vaginal mucosa.

Gross

  • Long cervix.

Microscopic

Features:

  • Uterus: non-specific.
  • Vaginal mucosa: (focal) keratinization due to rubbing - common finding.
