Definition :
It is benign of tumour or growth arising from the muscular layer of the uterus with intervening fibrous tissue.
Cause :
Types of fibroid :
Uterine fibroid :
It is benign of tumour or growth arising from the muscular layer of the uterus with intervening fibrous tissue.
Cause :
Age :
- Seen after menarche to menopause.
- Average - 30 to 35 years.
- Rare - before puberty and after menopause.
Hereditary :
- History of tumour in the family.
Parity :
- Common in nulliparous.
Mechanical stress :
- Fibromsculor reaction of the uterus to mechanical stress.
Ovarian function :
- Not clear but the oestrogen is responsible for the growth of fibroid so during pregnancy fibroid increase in size and reduces after menopause.

Uterine fibroid :
1. Corporeal fibroid :
- Interstitial
- Subserous
- Submucous
2. Cervical fibroid :
Interstitial or Intramural fibroid :
- Growth of fibroid in myometrium may push itself to form submucous or subserous.
- Commonest variety.
- A posterior wall more affected than the arterial wall.
Subserous fibroid :
- Growth below the peritoneal layer and away from the cavity.
- It may get attached to an abdominal organ and get blood supply from there and so detaching itself from myometrium and now it is called as wondering or parasitic fibroid.
- If wondering fibroid may produce in a layer of the broad ligament. It is known as ligament fibroid.
Submucous fibroid :
- It growing below a submucous layer of the uterus and protruding inside the uterine cavity may go to form submucous polyp with its direction towards internal os.
Pathology :
- Naked eye: Rarely single, frequently multiple.
- Microscopic: Spindle shape muscle tissue, between fibrous connective tissue.
Symptoms :
- It is mostly symptomless.
- Increase the endometrial surface.
- Increase vascularity.
- Haemostasis.
- Endometrial hyperplasia.
- Duration of period normal or prolonged.
- Loss of blood is heaviest on 2nd and 3rd menses.
Congestive and spasmodic dysmenorrhoea :
Pressure symptoms which are very rarely seen and they are the following :
- Per vaginal examination: White discharge seen in surface ulceration of submucosa and usually polypoid tumour.
- Metrorrhagia.
Pressure symptoms which are very rarely seen and they are the following :
- GIT dyspepsia.
- On bladder: Causing irritability with frequent urination.
- On vein and lymphatics: It leads to oedema and varicosity.
- On nerve: Feel the pain.
Symptom related to pregnancy :
- Subfertility either is the cause or effect of fibroid.
- Abortion or premature delivery by interfering growing embryo and initially of contracting.
- Malpresentation and malposition.
- Obstructed labour.
- It will be predisposed to 3rd stage difficulty and PPH also can cause delayed involution.
Signs :
General Examination :
- Pallor in case of excessive bleeding.
Per abdominal Examination :
- A firm lump is palpated arising out of the pelvis, the surface may be smooth or tubular.
- Restricted mobility from above downward.
- Percussion: Dull sound.
- Pelvic examination.
- Laparotomy confirms the diagnosis.
- Pelvic USG when clinically is not diagnosed or identified.
- Lab test: Pap smear of cervical epithelial.
- IVP: Uterine curettage.
Differential diagnosis :
- Adenomyosis.
- Pregnancy.
- Full bladder.
- Ovarian tumour.
- Broad ligament cyst or tumour.
- Tubo-ovarian mass.
Treatment :
- No medicine for symptomless fibroid but it is required when its size increased from 10 to 12 cm.
- In woman, at the age of menopause as there is a cessation of oestrogen and fibroid will itself disappear.
Palliative Surgery :
- Hormonal therapy.
- Bed rest.
- Blood transfusion in severe case.
- Uterine artery embolism through femoral artery by intra-arterial catheter and polyvinyl alcohol particles are injected to block artery and degeneration of fibroid to avoid degeneration.
Surgical Treatment :
- Myomectomy.
- Hysterectomy.
- Endoscopic resection.
- Polypectomy.
Complication :
- Torsion of subserous fibroid.
- Sarcoma
- Haemorrhage - Intracapsular and Intraperitoneal
Secondary changes :
- Degeneration: Red, Hyaline, Cystic, Fatty, Calcareous.
- Atrophy.
- Necrosis.
- Infection.
- Vascular change.
- Sarcomatous change.
