A case report demonstrating that simple mastectomy without axillary dissection can result in 5-year recurrence-free survival in a patient with primary angiosarcoma of the breast.
May support simple mastectomy without axillary dissection in select breast angiosarcoma; hypothesis-generating and requires validation in larger series.
Primary angiosarcoma of the breast is a rare disease, accounting only for 0.04% of all malignant breast tumors. Clinical and pathological diagnosis of angiosarcoma of the breast is often difficult due to its deceptively benign-appearance, but misdiagnosis is fatal because of the poor prognosis of the tumor. We experienced a case of angiosarcoma of the breast in a 46-year-old female, initially diagnosed as having cavernous hemangioma. Further investigation with suspicion of angiosarcoma allowed correct diagnosis of angiosarcoma of the breast. Simple mastectomy without axillary dissection was performed and the patient has had no evidence of recurrent disease for 5 years to date. Whenever we encounter with a vascular lesion associated with any breast mass, a high index of suspicion for angiosarcoma is essential.
