title: [A case of breast cancer with extensive osteonecrosis of maxilla induced by a bisphosphonate].
abstract: Here, we report a case of extensive osteonecrosis of the maxilla associated with a history of bisphosphonate (BP) therapy for management of bone metastases from breast cancer. A 66-year-old woman was referred to our hospital because of a fistulation on the right side of the maxilla in May 2005 by her dentist. The patient had a medical history of breast cancer with bone metastasis that was treated by chemotherapy with 45 mg pamidronate in 2 weekly courses for 16 months. We suspected that this rare case of osteonecrosis was caused by chemotherapy with BPs. Palliative treatments, including antibiotic therapy and local irrigation, were administered. Finally, extensive osteonecrosis of the maxilla occurred.
