Subcutaneous venous hemangioma of the breast

Breast hemangioma with difficulty in preoperative diagnosis: a case report

We report a rare case of breast hemangioma found in a 70-year-old Japanese female. Before seeking medical attention, the patient noticed a hard mass in her right breast but denied associated symptoms. A mammography revealed a well-circumscribed, highly dense, lobular nodule located in the middle inter portion of the right breast. To verify this finding, we used ultrasonography which revealed an irregular, iso-echoic nodule measuring 10 mm in the same portion. Based on these findings, we suspected a malignancy and performed a core needle biopsy. Unexpectedly, a histological examination of the biopsy displayed normal vasculature, adipose, and mammary tissues. In order to make an accurate diagnosis, the mass was surgically excised under general anesthesia and sent to pathology. Pathological findings of the mass were positive for breast hemangioma, and the patient has had no recurrence of the disease for the past 24 months.
