Elastosis in the normal aging breast. A histopathologic study of 140 cases

Area of Science:

• Pathology
• Breast Imaging
• Geriatric Medicine

Background:

• Elastosis, characterized by excess elastic fibers, is a histological finding in breast tissue.
• Its prevalence and patterns in relation to age and parity are not fully elucidated.
• Understanding elastosis is crucial for accurate breast tissue assessment.

Purpose of the Study:

• To investigate the incidence and patterns of breast elastosis in a cohort of women.
• To correlate elastosis with age, parity, and breast disease.
• To differentiate benign elastosis patterns from those potentially associated with malignancy.

Main Methods:

• Autopsy tissue specimens from 140 women aged 19-101 years with clinically normal breasts were analyzed.
• Histological examination focused on the presence and distribution of elastic fibers.
• Elastosis was assessed in stromal, perivascular, and periductal locations.

Main Results:

• Elastosis was observed in nearly half of women over 50 without breast disease.
• Periductal elastosis increased with age until approximately 50 years, likely related to parity.
• Stromal and perivascular elastosis showed less age-related correlation, with marked perivascular elastosis being uncommon.

Conclusions:

• Periductal elastosis is a common age-related finding and not typically a cause for concern.
• Marked perivascular elastosis is rare and may indicate a need for further investigation for breast cancer.
• Elastosis patterns provide insights into breast tissue changes with aging and parity.
