FNAC of a breast lesion after treatment for carcinoma

摘要

Vascular lesions of the breast are rare and the vast majority are malignant.1 The clinical diagnosis of a benign vascular lesion is rather difficult because it is rarely grossly apparent and usually discovered on microscopic examination. Herein, we report a case of non-palpable haemangioma with papillary endothelial hyperplasia (PEH) of the breast which went unsuspected at the ultrasound and mammography examinations, but was highly suspected by fine needle aspiration cytology (FNAC) and confirmed histologically after surgical excision of the lesion.A 64-year-old woman with an invasive ductal carcinoma of the left breast, treated 12 years earlier by tumourectomy and axillary lymph node dissection plus radiation therapy, presented with an 8 mm nonpalpable left breast lesion located in the lower-inner quadrant on a screening mammography. This nodule was radio logically scored as BI-RADS 4, according to the American College of Radiology classification.
