Step 1: Introduction to Leiomyoma Uterus.
Leiomyomas, also known as fibroids, are benign smooth muscle tumors of the uterus. The FIGO (International Federation of Gynecology and Obstetrics) classification system categorizes these fibroids based on their location within the uterus.
Step 2: FIGO Classification of Leiomyoma Uterus.
The FIGO classification of uterine fibroids is as follows:
- Type 0: Submucosal fibroids – These are located just beneath the endometrium (inner lining of the uterus) and may protrude into the uterine cavity.
- Type 1: Intramural fibroids – These are located within the muscular wall of the uterus but do not distort the uterine cavity.
- Type 2: Subserosal fibroids – These are located just beneath the outer lining of the uterus (seros and may protrude outward.
- Type 3: Pedunculated fibroids – These are fibroids that grow on a stalk either inside the uterine cavity or on the outer surface of the uterus.
