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 haemangioma, cavernous type.
Haemangiomas are rare benign vascular tumors in the breast with incidence between 1.2% (if clinical detested) and 11% (in post-mortem specimens).
They generally are located superficially in the subcutaneous tissue and as such are palpable.
Cavernous haemangiomas are the most common type.
Their progression to malignant change is controversial.
