Blue Lymphangitis of the Breast after Breast Cancer: Case Report.

ABSTRACT

Carcinomatous lymphangitis accounts for 5% of all skin metastases, but blue lymphangitis of the breast has never been described. We report a case of blue lymphangitis of the breast in a patient 11 years after treatment for ipsilateral breast cancer that was in full remission. Breast examination and imaging showed no other abnormalities. Skin biopsy revealed a carcinomatous-pigmented infiltration corresponding to melanoma metastasis, which helped highlight a primitive right flank injury. This case report emphasizes that a full body exam should always be performed with unusual presentation of breast cancer and reiterates the indispensable place of histology before any diagnosis.
