    Periductal mastitis, characterized by inflammation, appears to precede duct dilatation in mammary duct ectasia. Parity and breastfeeding history do not significantly influence the development of this condition.

    Area of Science:

    • Breast pathology
    • Mammary gland disorders

    Background:

    • Mammary duct ectasia (MDE) is a common breast condition.
    • Understanding the early pathological changes and etiological factors in MDE is crucial for effective management.

    Purpose of the Study:

    • To investigate the relationship between histological findings and clinical presentation in patients with MDE.
    • To explore the role of parity and breastfeeding in the etiology of MDE.

    Main Methods:

    • Retrospective review of 108 patients diagnosed with MDE.
    • Histological analysis of breast biopsies from 88 patients.
    • Comparison of parity and breastfeeding history with age-matched control groups.

    Main Results:

    • Younger patients with MDE presented with breast pain or lumps, associated with severe periductal inflammation.

  • Older patients showed duct dilatation as the primary feature, linked to nipple retraction.
  • No significant differences in parity or breastfeeding history were found between MDE patients and control groups.
  • Conclusions:

    • Severe periductal mastitis likely precedes duct dilatation, representing the initial stage of MDE.
    • Parity and breastfeeding are not significant etiological factors in the development of MDE.
