Cutaneous metastases from breast carcinoma.

We report the case of a rare presentation of cutaneous metastatic breast carcinoma. A 72-year-old lady who was previously fit and well presented with a 2-month history of a rash over the left breast. Clinically, in addition to the rash, she had a fixed tender mass of left supraclavicular fossa and left axillary lymph nodes. Punch biopsy of the skin demonstrated metastatic carcinoma and ultrasound of the left breast revealed a 9 mm irregular mass which was biopsied, demonstrating poorly differentiated grade III adenocarcinoma. She was oestrogen receptor negative but human epidermal growth factor receptor-2 positive on immunohistochemistry. She is currently undergoing chemotherapy with taxotere and herceptin.
