Montgomery's areolar tubercle. A light microscopic study.

D M Smith, T G Peters, W L Donegan

    Archives of Pathology & Laboratory Medicine
    |February 1, 1982
    PubMed
    Summary

    Montgomery's areolar tubercles contain both sebaceous glands and mammary ducts. Breast diseases can affect the areola directly, independent of nipple involvement, impacting surgical decisions.

    Area of Science:

    • Surgical anatomy
    • Dermatopathology
    • Breast oncology

    Background:

    • Montgomery's areolar tubercles are skin structures with debated anatomy.
    • Previous studies have not fully elucidated the relationship between sebaceous glands and mammary ducts within these tubercles.

    Purpose of the Study:

    • To clarify the detailed microscopic anatomy of Montgomery's areolar tubercles.
    • To investigate the potential for mammary duct involvement within the areolar tubercles.
    • To assess the implications of these findings for breast disease and surgical approaches.

    Main Methods:

    • Analysis of 35 Montgomery's areolar tubercles from 12 modified radical mastectomy specimens.
    • Serial sectioning of tubercles for detailed histopathological examination.

    Main Results:

    • A mammary lactiferous duct was found associated with the sebaceous apparatus in 34 of 35 tubercles (97%).
    • The lactiferous duct originated from deeper breast parenchyma and entered the sebaceous gland.
    • Histopathologic findings included fibrocystic disease, atypical intraductal hyperplasia, and carcinoma in situ within the tubercles.

    Conclusions:

    • Montgomery's areolar tubercle is composed of both sebaceous glands and mammary ducts.
    • Breast diseases can involve the areola independently of the nipple-areolar complex, necessitating careful consideration during surgery.
    • Areolar preservation strategies should account for potential underlying mammary pathology.
