Retromammary Space

The fibroglandular tissue is surrounded by mostly fatty tissue in the subcutaneous and retromammary retroglandular regions fig.

Retromammary space. The retromammary space is located between the membranous layer of superficial fascia and the deep fascia covering the muscles of the thorax. Retromammary space breast cancer is cancer that develops from breast tissue. As the loose connective tissue of the retromammary space delineates the breast from the underlying pectoralis major the suspensory ligaments of cooper anchor the breast onto the pectoralis major fascia and the dermis.

It allows for movement of the breast tissue. The mobility of the female breast on the body wall is largely due to this space. D lies between the fatty matrix and the glandular tissue. Deep layer deep fascia lies posterior to the mammary layer within the retromammary space irregularities of the deep fascia posterior to a malignancy can indicate metastasis to the chest wall terminal ductolobular unit tdlu.

The retromammary space is a potential space between the breast tissue and the underlying pectoralis fascia. It contains loose connective tissue and aids in mobility of the breast on the thoracic wall. The upper outer quadrant typically contains more fibroglandular tissue than the other quadrants and is where cancers are most likely to develop.
