Infiltrating ductal carcinoma: infiltrates at the exit site of a central venous access port device.

摘要

A 76-year-old woman with past history of hypertension and diabetes was referred to the breast cancer unit in June 2007 for a right breast palpable mass measuring 2.5 cm with axillary involvement. The core needle biopsy showed an infiltrating ductal carcinoma and a right breast-conserving surgery with axillary lymph node dissection was carried out. The pathology revealed a 3-cm invasive ductal carcinoma grade III with involvement of 22 of 25 axillary lymph nodes. The tumor was hormone receptor positive and her-2 negative and the resection margins were negative. When transferred to the oncology unit in August 2007, the patient referred low back pain. X-ray findings were consistent with sclerotic metastatic bone disease and a bone scintigraphy confirmed bone metastases in the spine, the pelvis bone and the ribs. In the context of a patient with hormone-dependent metastatic bone disease, local radiotherapy was dismissed and first-line endocrine therapy and bisphosphonates were initiated. Bisphosphonates were administered intravenously through a central venous access port device (CVAPD), which had been placed in the right internal jugular vein soon after the surgery.
