Triple negative breast cancer with interscapular metastasis

Abstract

Triple-negative breast cancer is a rare but difficult-to-manage clinical presentation of breast cancer, of which soft tissue metastasis as the first clinical manifestation is rare. In the United States, 1 in 8 women will develop invasive breast cancer in her lifetime. The objective of the work is to demonstrate unusual behavior of the manifestation of breast cancer, through a presentation of a clinical case. The diagnosis of the primary was obtained thanks to immunohistochemistry of the resection of the metastatic tumor in the skin. The case reported here integrates three points of interest: triple negative breast cancer, it affects a 58-year-old woman and metastatic interscapular tumor to soft tissue, which makes an unusual behavior of breast cancer since skin metastases occur between 0.6% and 10.4% in this type of breast cancer.
