The patient presented above was diagnosed with invasive ductal carcinoma (IDC) in the right breast in 2003. First signs of bone metastasis to the pelvis and left femur were found on 2009. Multiple therapies were attempted since then, including radical mastectomy, radiotherapy, chemotherapy, hormone and immunotherapy. Unfortunately, the treatment attempts had a minimum effect and eventually, the patients' bone metastases became resistant to almost every therapy, which is usually expected in this scenarios¹, and finally evolving to the event previously described.

A pathologic fracture is a common event in patients with bone metastasis from breast cancer, as the skeleton is the most frequent site for metastases², noting that there is a particular preference for the proximal femur³.
