Summary
Histological classification of the endometrium in perimenopausal women often fails due to mixed patterns. Most adequate endometrial biopsy specimens showed abnormal secretory endometrium or mixed histological features.
Area of Science:
- Gynecology
- Reproductive Endocrinology
- Histopathology
Background:
- Perimenopause is a transitional phase characterized by hormonal fluctuations.
- Endometrial histology is crucial for evaluating reproductive health.
Purpose of the Study:
- To evaluate endometrial histology patterns in perimenopausal women.
- To assess the applicability of standard endometrial classification systems in this demographic.
Main Methods:
- Light microscopy analysis of 202 endometrial biopsies from perimenopausal women.
- Assessment of histological patterns using suction curettage specimens.
Main Results:
- 82 out of 142 adequate specimens (57.7%) exhibited mixed histological patterns, defying standard classification.
- Abnormal secretory endometrium was observed in 41.5% of cases.
- Disordered proliferative endometrium and mixed non-secretory/secretory patterns were also noted.
Conclusions:
- Standard endometrial histological classification, based on regular cyclic changes, is often inadequate for perimenopausal women.
- Mixed histological patterns within a single biopsy are common, complicating diagnosis.
- Further refinement of classification systems may be needed for perimenopausal endometrium.
