A fine needle cytology was performed and no malignant cells were detected.
As the lesion had increased in size compared to a previous mammogram 2 years earlier, it was completely excised under local anesthesia. The final histological diagnosis was hemangioma, cavernous type.
Breast hemangiomas are rare benign vascular tumors in the breast with incidence between 1.2% (if clinically detested) and 11% (in post-mortem specimens). They generally are located superficially in the subcutaneous tissue and as such are palpable. Cavernous hemangiomas are the most common type. Their progression to malignant change is controversial.
