2.  A uterine fibroid (also uterine leiomyoma, myoma, fibromyoma, leiofibromyoma, fibroleiomyoma, and fibroma) (plural of... myoma is...myomas or...myomata) is a benign (non-cancerous) tumor that originates from the smooth muscle layer (myometrium) and the accompanying connective tissue of the uterus. benigntumormyometriumuterusbenigntumormyometriumuterus

3.  Fibroids are the most common benign tumors in females and typically found during the middle and later reproductive years. While most fibroids are asymptomatic, they can grow and cause heavy and painful menstruation, painful sexual intercourse, and urinary frequency and urgency. Some fibroids may interfere with pregnancy although this appears to be very rare.

4. Uterine fibroids Present in up to 25% of women of reproductive age.  Fibroids are most common in women aged 30-40, but they can occur at any age.  Fibroids occur more often in black women than in white women.  They associated with nulliparity and more common in women with family history of fibroids and obesity.

5.  The incidence is decreased with:  Prolonged use of the oral contraceptive pill.  Prolonged use of Depo-provera.  increasing numbers of term pregnancies.  smoking.  Fibroids regress in size and undergo degeneration after the menopause.

6. The exact causes of fibroid are not well understood but research and clinical experience point to several factors: The exact causes of fibroid are not well understood but research and clinical experience point to several factors: Genetic alterations. Many fibroids contain alterations in genes that code for uterine muscle cells. Genetic alterations. Many fibroids contain alterations in genes that code for uterine muscle cells. Hormones. Estrogen and progesterone, two hormones that stimulate development of the uterine lining in preparation for pregnancy, appear to promote the growth of fibroids. Fibroids contain more estrogen and estrogen receptors than do normal uterine muscle cells. Hormones.

7. Intramural Fibroids are located within the wall of the uterus and are the most common type; unless large, they may be asymptomatic. Intramural fibroids begin as small nodules in the muscular wall of the uterus. With time, intramural fibroids may expand inwards, causing distortion and elongation of the uterine cavity. Intramural Fibroids are located within the wall of the uterus and are the most common type; unless large, they may be asymptomatic. Intramural fibroids begin as small nodules in the muscular wall of the uterus. With time, intramural fibroids may expand inwards, causing distortion and elongation of the uterine cavity. Subserosal fibroids are located underneath the mucosal (peritoneal) surface of the uterus and can become very large. They can also grow out in a papillary manner to become pedunculated fibroids. These pedunculated growths can actually detach from the uterus to become a parasitic leiomyoma. Subserosal fibroids are located underneath the mucosal (peritoneal) surface of the uterus and can become very large. They can also grow out in a papillary manner to become pedunculated fibroids. These pedunculated growths can actually detach from the uterus to become a parasitic leiomyoma. Submucosal fibroids are located in the muscle beneath the endometrium of the uterus and distort the uterine cavity; even small lesion in this location may lead to bleeding and infertility. A pedunculated lesion within the cavity is termed an intracavitary fibroid and can be passed through the cervix.

A pedunculated lesion within the cavity is termed an intracavitary fibroid and can be passed through the cervix.infertility Cervical fibroids are located in the wall of the cervix (neck of the uterus). Rarely fibroids are found in the supporting structures (round ligament, broad ligament, or uterosacral ligament) of the uterus that also contain smooth muscle tissue.

12.  Leiomyomas grossly appear as round, well circumscribed (but not encapsulated), solid nodules that are white or tan, and show whorled appearance on histological section. The size varies, from microscopic to lesions of considerable size. Typically lesions the size of a grapefruit or bigger are felt by the patient herself through the abdominal wall.

14.  Microscopically, tumor cells resemble normal cells (elongated, spindle-shaped, with a cigar- shaped nucleus) and form bundles with different directions (whorled). These cells are uniform in size and shape, with scarce mitoses. There are three benign variants: bizarre (atypical); cellular; and mitotically active. mitotically

34.  Most fibroids do not require treatment unless they are causing symptoms. After menopause fibroids shrink and it is unusual for fibroids to cause problems.  Symptomatic uterine fibroids can be treated by:  1.medication to control symptoms  2.medication aimed at shrinking tumours  3.ultrasound fibroid destruction  4.various surgically aided methods to reduce blood supply of fibroids  5.myomectomy or radio frequency ablation  6.hysterectomy

35.  Treatment must be individualized according to:  Patient (age-parity-symptoms).  Fibroid (number-size-type-rate of growth).  Complications associated with fibroids.

36.  Approximately 80% of fibroids are asymptomatic and are smaller in size than a twelve week gestation uterus do not need to be removed and may be followed clinically. Observation with periodic examination (every 3 to 6 months) is appropriate to rule out a rapidly growing uterine sarcoma. After assurance of slow growth or stable uterine size, annual follow-up may be appropriate.

37.  Medical treatment  1.medication to control symptoms  Treatment of symptom as menorrhagia  GnRH agonists;  It induce a hypoestrogenic pseudo-menopausal state and causes shrinkage of the fibroids.  GnRH agonist treatment is not recommended for longer than 6 months because of the potential consequent development of osteoporosis.  Side effect; hot flashes and osteoporosis.

38. Re-growth of fibroids is experienced within a few months, and for this reason its use is recommended for short-term treatment in selected cases which are: Re-growth of fibroids is experienced within a few months, and for this reason its use is recommended for short-term treatment in selected cases which are:  1.Treatment of women approaching menopause in an effort to avoid surgery.  2. Short-term therapy may be used preoperatively (at any age) in the following situations:  A. pre-surgical treatment to decrease symptoms and size which might make surgery easier or permit a more conservative approach such as a vaginal or laparoscopic surgical approach rather than abdominal approach  B. control bleeding prior to surgery (so that anemia might be corrected).

40.  There are two general types of surgery available for fibroids and its choice depends on:  Patients wishes and parity  Fibroid size and number  Location of the fibroids.

41.  Myomectomy  Polypectomy.  Hysterectomy  Hysterectomy.

42.  Involves the removal of single or multiple fibroids while preserving the uterus.  Myomectomy may be performed in a number of ways. The method used depends on the location and size of the fibroids.  1. Laparotomy (Abdominal myomectomy)  2. Laparoscopic myomectomy.  3. Hysteroscopic myomectomy (submucosal fibroids).

44.  1.Abdominal myomectomy has been associated with more significant blood loss.  2.Abdominal myomectomy has been associated with higher morbidity than hysterectomy.  3.The risk of recurrence after myomectomy has been estimated to be 27% after 10 years.  4.With larger fibroids, attempted myomectomy frequently results in hysterectomy due to uncontrollable bleeding in these highly vascular tumors.  5.if the endometrial cavity is entered during myomectomy, future deliveries must be by caesarean section.

45.  It is a definitive therapy for uterine fibroids. (The only real "cure" for fibroids).  Hysterectomy may be considered when:  Pain or abnormal bleeding persists.  Fibroids are very large.(uterus is large >12- 14weeks)  Other treatments are not possible.  A woman no longer wants children.  A rapid growth of the uterus caused by fibroids

46.  Abdominal hysterectomy  Vaginal hysterectomy.  Laparoscopically assisted vaginal hysterectomy  Laparoscopically assisted vaginal hysterectomy.

47.  Is a promising new method of treating symptomatic fibroids. In this procedure, Embolization of the uterine arteries supplying the fibroids.

48.  A small number of pregnant women have uterine fibroids  A small number of pregnant women have uterine fibroids.

49.  Enlarge.  Become softer,flatten out and become indistinct.  May be mistaken for fetal parts.  Certain accident and degenerations are more common in fibroids during pregnancy:  Red degeneration of fibroids. occur in 5-10% of women with fibroids..  Torsion of pedunculated fibroids.( more in puerperium).  Infection in fibroids after delivery or abortion.

50.  Fibroids can increase the risk of :  Large for date uterus  Abortion.  preterm labour  abruption placenta.  Fetal malpresentation.  Obstructed labour.  Increase incidence of caesarean section.  retained placental tissue.  Increase risk of post partum haemorrhage (PPH).  Delayed involuation of uterus

51.  Usually no treatment of fibroids is needed during pregnancy. Myomectomy should not be performed in pregnant women because of the increased risk of uncontrolled bleeding. 
