Evolution and prognosis of breast osteosarcoma: A case report

Area of Science:

• Oncology
• Pathology

Background:

• Breast osteosarcoma is a rare malignancy with unknown causes and no standard treatments.
• The disease has a poor prognosis, with a high tendency for recurrence and metastasis.

Purpose of the Study:

• To present a case of breast osteosarcoma developing from adenomyoepithelioma.
• To describe the clinical characteristics and treatment of this rare breast cancer.

Main Methods:

• Case report of a 52-year-old woman with breast osteosarcoma.
• Review of patient's medical history, including surgeries, chemotherapy (liposomal doxorubicin and cisplatin), and molecular-targeted therapy (sunitinib).

Main Results:

• The patient's adenomyoepithelioma transformed into breast osteosarcoma over time.
• The patient survived 41 months, but ultimately succumbed to respiratory failure due to progressive disease and lung metastasis.

Conclusions:

• This case demonstrates a clear pathological transformation process in breast osteosarcoma.
• Further research into the clinical characteristics and treatment of breast osteosarcoma is warranted.
