Case:
A 40 year-old female smoker presented to her primary care physician complaining of a painful lesion on her right breast. The patient reported having a scant non-bloody nipple discharge. She also noted that the lesion had slowly increased in size during the past 5 months. The patient had no personal or family history of breast cancer and had never had a mammogram. Upon physical examination, a smooth, ?rm mass approximately 2.0 cm in diameter could be located centrally beneath the nipple. Her skin was tender but without ulceration or erythema. A fine needle aspiration biopsy (FNA) was performed without complications.
