Breast cancer is the second leading cause of cancer deaths in women. In 2014, it is estimated that there will be 232,670 new cases of breast cancer and an estimated 40,000 people will die of this disease. About 60.8% of breast cancer is diagnosed at the local stage, with a 5-year survival of 98.5%. In contrast, 5% of breast cancer cases are diagnosed with metastasis, with a 5-year survival of 25%.
Invasive lobular carcinoma of the breast, sometimes referred to as the infiltrating lobular carcinoma, is the second most common cause of breast cancer, following invasive ductal carcinoma. The sites of metastatic spread differ between infiltrating ductal carcinoma and invasive lobular carcinoma. While in infiltrating ductal carcinoma, the common sites of metastatic disease are in the lung, bones, and liver, in invasive lobular carcinoma, metastatic disease has been reported in the GI tract, peritoneum, and retroperitoneum. Little data exists about metastasis of lobular carcinoma cells to inorganic materials.
We present a case report in a 68 yo female with T2N2aMx metastatic invasive lobular carcinoma of the breast who presented with metastasis in her abdominal hernia mesh one year after her mastectomy.
