Breast tissue inclusions in axillary lymph nodes

D R Turner, R R Millis

    Histopathology
    |November 1, 1980
    PubMed
    Summary

    Benign epithelial hyperplasia in lymph nodes can mimic metastatic breast cancer. This case highlights the risk of misdiagnosis, especially with cryostat sections, emphasizing careful pathological evaluation.

    Area of Science:

    • Pathology
    • Oncology
    • Surgical Pathology

    Background:

    • A 54-year-old female presented with a history of benign epithelial hyperplasia on repeated breast biopsies.
    • The patient underwent a simple mastectomy and axillary lymph node biopsy for further evaluation.

    Observation:

    • Histopathological examination revealed numerous foci of epithelial hyperplasia in the breast tissue.
    • A significant finding was an axillary lymph node extensively replaced by similar hyperplastic epithelial tissue.

    Findings:

    • No evidence of malignancy was detected in the breast or lymph node specimens.
    • The extensive epithelial hyperplasia in the lymph node mimicked metastatic malignancy.

    Implications:

    • Highlights the critical danger of misinterpreting benign epithelial inclusions in lymph nodes as metastatic cancer.
    • Emphasizes the importance of meticulous examination, particularly with rapid cryostat sectioning, to avoid diagnostic errors in breast pathology.
    • Suggests further investigation into the etiology of such lymph node lesions.
