Metastatic Lobular Breast Cancer Mimicking Colitis
Breast cancer is the most frequent cancer diagnosed in women in the world regardless of race or ethnicity. About 10% of invasive breast carcinomas are lobular subtype. The loss of the E-caderin expression that occurs in lobular carcinoma leads to a higher risk of metastases in membranes (meningeal,...

| description | Breast cancer is the most frequent cancer diagnosed in women in the world regardless of race or ethnicity. About 10% of invasive breast carcinomas are lobular subtype. The loss of the E-caderin expression that occurs in lobular carcinoma leads to a higher risk of metastases in membranes (meningeal, pleural, peritoneum) and gastrointestinal and/or endobronchial mucous, which may lead to several odd symptomatology. We report a 79 years old female patient with lobular breast cancer associated to CDH1 germline mutation. She was diagnosed with breast cancer in December 2016 after noticing a right-armpit nodule whose pathological examination demonstrated an immunohistochemistry profile compatible with lobular breast carcinoma metastasis and had estrogen receptors 98%, progesterone receptors < 1%, ki67 25%, negative her2 score. Family history of only one paternal uncle with stomach cancer. After two lines of hormone therapy, she had disease progression and started oral chemotherapy with capecitabine. In a few weeks, the patient had refractory diarrhea. At the beginning, it was defined like colitis chemotherapy related. However, the clinical features showed necessity of further investigation. Then, she was diagnosed with CDH1 germline mutation after massive progression at gastrointestinal mucous. This case made possible to inform the family about risk of germline mutation and necessity of genetic counseling. |
