FIGO classification system for uterine leiomyoma
Updates to Article Attributes
The FIGO classification system for uterine leiomyoma (fibroids) classifies uterine leiomyomas based on location.
Usage
This classification system was developed for clinical and research purposes 2, however, in clinical use, there is significant variation in agreement 3.
Classification
Submucosal group
type 0: pedunculated intracavitary
type 1: <50% intramural
type 2: ≥50% intramural
Other group
type 3: 100% intramural; contacts endometrium
type 4: intramural
type 5: subserosal ≥50% intramural
type 6: subserosal <50% intramural
type 7: subserosal pedunculated
Hybrid leiomyoma group
leiomyomas that impact both the endometrium and serosa
two numbers listed separately separated by a hyphen with the first number indicating the endometrial relationship and the second number the serosal relationship
