High grade angiosarcoma fifteen years after breast conservation therapy with radiation therapy: A case report.

INTRODUCTION

Angiosarcoma is a rare tumor of the breast. Secondary angiosarcoma of the breast refers specifically to a tumor that arises after a latency period following radiation. With breast conservation therapy gaining significant popularity to that of mastectomy, more cases of secondary angiosarcoma continue to arise in the irradiated fields of these patients.

PRESENTATION OF CASE

The authors describe the case of an 80 year old female who presented fifteen years after her surgery and radiation treatment with two bleeding skin lesions in her breast. These lesions were found to be high grade angiosarcoma upon excision. Due to high cardiac co-morbidity she was treated with re-excision and surveillance.

DISCUSSION

This case is an example of a rare sequela to a common procedure. Breast conservation therapy with lumpectomy and radiation has become a popular technique in treating localized breast cancer. Radiation like all therapy has its known adverse effects. Further work is needed with the small amount of published cases of angiosarcoma after breast irradiation so that we may find optimal treatment plans for these patients. Like any rare entity, difficulty lies in accruing enough cases to compare prognosis and results.

CONCLUSION

Secondary breast angiosarcoma diagnosis requires frequent follow ups and a high index of suspicion. With mastectomy giving the best chance of treatment in these cases, early detection is crucial in this rare sequela.
