Invasive ductal breast cancer with extensive subcutaneous metastases in trunk: a case report

The metastases sites of advanced breast cancer contain vast majority of tissues and organs, which most common are bones, lungs, liver, brain and distant lymph nodes. We report a woman with unusual extensive subcutaneous metastases of breast cancer in her abdomen, back and back of the neck. The patient was diagnosed with invasive ductal breast cancer and had been treated 4 months earlier with modified radical mastectomy and three cycles of chemotherapy. Later she presented painless multiple small tubercules on the abdomen wall, back and back of the neck. She sought treatment in our department to perform a 18FDG PET-CT scan, confirming the multiple subcutaneous tubercules. Histopathological studies supported that the tubercules were rare subcutaneous metastatic of breast origin. The patient underwent another two cycles of chemotherapy and evaluation of curative effect was stability.
