The main features used in proposed classification systems for adenomyosis.
| Reference | Categories/Basis of Classification |
|---|---|
| Histopathology | |
| Bird et al. (1972) Sammour et al. (2002) |
Depth of invasion within the mometrium Degree of involvement: Number of glands per low power field |
| Siegler and Camilien (1994) Hulka et al. (2002) Vercellini et al. (2006) |
Depth of penetration Degree of involvement Configuration: Diffuse, discrete. |
| Levgur et al. (2000) | Depth of invasion |
| Ultrasound based | |
| Lazzeri et al. (2018) | Configuration Depth of lesion (affecting Junctional zone, inner, outer myometrium) |
| MRI based | |
| Grodts et al. (2008) | JZ hyperplasia Adenomyosis Adenomyoma |
| Kishi et al. (2012) | Subtype I: Intrinsic: Inner uterine layer Subtype II: Extrinsic: Outer uterine layer (normal JZ) Subtype III: Solitary adenomyosis no connection to the JZ or to the serosa. Subtype IV: Indeterminate |
