RESUMO
Flaxseed oil contains lignans, which exhibit anti-inflammatory and antiatherogenic activities. A 70-year-old male patient presented to our office due to hyperlipidaemia and started to take a tablespoon of flaxseed oil daily. Three months later, he reported left breast swelling and pain. Although the echogram revealed a tumour in the left mammary gland, the breast biopsy was compatible with gynecomastia, showing ductal hyperplasia without evidence of malignancy. His breast epithelia were oestrogen receptor-positive. Potential role of phytoestrogens was discussed.
