2. Uterine Fibroids
LEIOMYOMA

3. Leiomyoma
 Leimyoma are benign tumors that grow
from the muscular wall Myometrium of the
uterus.

4.  Leiomyoma are composed of Fibrous tissue
and smooth muscels.
 They are the most common uterine tumors.

6. Etiology
 Unknown
 There may be genetic predisposition
 Leiomyoma contain estrogen receptors in high
concentration than surrounding myometrium.
 They may increase with estrogen therapy and in
pregnency.

7. Classification
They are classified on the basis of their location in uterus.
o Submucosal leiomyoma
o Pedunculated intracavity
o Intramural
o Subserous
o Pedunculated abdominal
o Parasitic
o Intraligmentary
o Cervical

9. Submucosl Leiomyoma
present behind mucous layer

12. Pedunculated intracavity
behind mucous layer and hanging with a stalk

15. Intramural leiomyoma
located in the center of uterine wall

18. Subserosal leiomyoma
 Located behind serosal layer

21. Pedunculated abdominal
It present outside from uterus, in abdomen.
And attached by a stalk

24. Cervical fibroids
 Present in the neck of cervix

26. Clinical Findings

27. PAIN
 vasscular occlusion > infection,necrosis
 Myometrial contraction to expel fibroid
 If goes to pelvic cause nerve compression
and back pain leading to lower extremities

28. Abnormal uterine bleeding
 Due to distorsion ang congestion of
surrounding vessels

29. Pressure Effects
 If large may obstruct the nearby organs like
ureters,bladder,rectum.
 Hydronephrosis
 Frequent urination
 May cause bowel obstruction

30. Infertility
 Infertility occurs mostly by fibroids pedunculted
in the uterine cavity.

31. Spontaneous Abortions
 Due to pressure of fibroid on fetus to expel
 Mostly due to fibroids pedunculated in cavity

32. Overview
 Leiomyoma are benign tumors arise from
muscular layer Myometrium of uterus.
 Etiology is unknows but related to estrogen.

33. Classification
o Submucosal leiomyoma
o Pedunculated intracavity
o Intramural
o Subserous
o Pedunculated abdominal
o Parasitic
o Intraligmentary
o Cervical

34. Clinical Findings
 Pain
 Uterine Bleeding
 Pressure Effects
 Infertility
 Spontaneous Abortion
