    Pectoral lymph nodes are often found in the axillary tail during mastectomy. These nodes are continuous with pectoral nodes and identified in 90% of patients, even without axillary dissection.

    Area of Science:

    • Oncology
    • Surgical Oncology
    • Anatomy

    Background:

    • The axillary tail of the breast is an extension of breast tissue towards the axilla.
    • Pectoral lymph nodes are crucial in breast cancer metastasis.
    • Understanding lymph node distribution is vital for accurate staging and treatment planning.

    Purpose of the Study:

    • To investigate the distribution and presence of pectoral (external mammary) lymph nodes within the axillary tail.
    • To determine the frequency of pectoral lymph node identification in patients undergoing simple mastectomy without axillary dissection.

    Main Methods:

    • Retrospective analysis of 45 patients who underwent simple (total) mastectomy.
    • Intraoperative identification and documentation of pectoral lymph nodes within the axillary tail.

  • Examination of lymph node continuity with pectoral nodes.

    • Main Results:

    • Up to 13 pectoral lymph nodes can be present within the axillary tail.
    • Pectoral lymph nodes in the axillary tail are continuous with the main pectoral lymph node group.
    • Lymph nodes were identified in 90% of patients undergoing simple mastectomy without axillary dissection.

    Conclusions:

    • Pectoral lymph nodes are frequently located within the axillary tail.
    • Simple mastectomy without axillary dissection still allows for the identification of these important nodes.
    • This finding has implications for surgical planning and staging in breast cancer patients.
