Summary
Focal pregnancy-like mammary changes in non-pregnant women are common in breast tissue, often linked to hormone exposure. These findings suggest a normal histological variant indicating mammary tissue
Area of Science:
- Histopathology
- Endocrinology
- Gynecology
Background:
- Focal, pregnancy-like mammary changes can occur in women who are not pregnant or lactating.
- These histological findings are observed in a small percentage of breast tissue specimens.
Purpose of the Study:
- To discuss the etiology of focal, pregnancy-like mammary changes in non-pregnant, non-lactating women.
- To analyze a case series of 31 patients with these mammary changes.
Main Methods:
- Literature review on mammary changes.
- Histopathological examination of breast tissue specimens from 31 patients.
Main Results:
- Pregnancy-like changes were found in 3% of breast tissue specimens.
- These changes were associated with prior pregnancy, estrogenic or contraceptive medication, and occurred across different age groups.
- The changes were also noted in individuals without prior pregnancy or hormone use, and in men on estrogen therapy.
Conclusions:
- Focal pregnancy-like mammary changes in non-pregnant women likely indicate selective mammary glandular tissue susceptibility to estrogen.
- These changes are interpreted as a normal histological variant.
