Metastatic carcinoma of the breast with inguinal lymph node involvement: a report of two cases.

Nigerian journal of clinical practice 11(4):383 (2008) PMID 19320417

Metastatic carcinoma of the breast may display varied clinicopathological patterns. Lymphatic spread to the inguinal lymph nodes is, however, very rare. To report two cases of advanced breast carcinoma with metastases to the inguinal lymph nodes in two Nigerian women. The University of Port Harcourt Teaching Hospital, Port Harcourt, Nigeria. Two Nigerian women, one aged 40 years with an invasive lobular carcinoma of the right breast, and the other aged 48 years with an infiltrating ductal carcinoma of the left breast, presented with metastases to their corresponding inguinal lymph nodes diagnosed by open biopsy. The first had a right simple mastectomy done and was lost to follow up before any adjuvant therapy could be administered. The second died before any definitive treatment could be offered. Metastasis to the inguinal nodes is rare and signifies an advanced disease. The pathogenesis is speculative, probably from retrograde embolisation.
