Uterus
Revision as of 14:37, 28 April 2012 by Michael (talk | contribs) (→Specific conditions: +uterus didelphys)
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.
- Indication: uterine leiomyomas.
- Subtotal hysterectomy.
- Discouraged... as the cervix remains and can develop a cancer.
- Total hysterectomy.
- Indications: endometrial cancer (low stage, good histologic type), endometrial hyperplasia, uterine prolapse, uterine adenomyosis, uterine leiomyomas.
- 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.
- Indications: cervical cancers, advanced uterine cancers.
Notes:
- There are almost no quality of life differences between total & subtotal hysterectomy.[2]
Tumours of the corpus
Main article: Uterine tumours
The most common is leiomyoma (uterine fibroids).
Endometrium
Main article: 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).
Features:[3]
- Subdivided - as etiologies differ.
- Thought to have a genetic component - autosomal dominant with variable penetration.
Treatment:
- Uterine transplant - attempted.[4]
Uterus didelphys
General
- Benign - though may adversely affect fertility.[5]
- Rare - seen in < 0.3% deliveries.[6]
- Can be thought of as double uterus - a consequence of the Muellerian ducts not fusing.
Related conditions:
- Arcuate uterus - fundus has a concave contour towards the uterine cavity.
- Septate uterus.
- Bicornuate uterus.
- Uterus didelphys.
Gross
- Two uteri - each have a cervix and one connect to one fallopian tube.
- +/-Vaginal septum or double vagina.[6]
Microscopic
- Non-specific - gross diagnosis.
Uterine adenomyosis
- AKA adenomyosis of the uterus.
General
- Common - may be a cause of bleeding.[7]
- Associated with endometriosis. (???)
Microscopic
Features:
- Endometrial glands within uterine muscle - key feature.
- Endometrial glands:
- Circular.
- Simple epithelial or pseudostratified epithelium +/- mitoses.
- +/-Surrounded by endometrial stroma.
- Densely packed spindle cells without nuclear atypia.
- Blood:
- Within glands.
- Hemosiderin-laden macrophages.
- Endometrial glands:
Note:
- Can be thought of as endometriosis of the myometrium.
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.
