A 61-year-old woman presented with low-back pain. Three years earlier,
she had been diagnosed with stage II breast cancer (node and estrogen
-receptor positive). She had had a mastectomy and received tamoxifen.
On physical examination, the lumbar spine was tender on palpation, and
she had enlarged supraclavicular nodes. Bone scan showed increased up
take at multiple sites, including the lumbar spine, consistent with me
tastatic cancer. Fine-needle aspiration of a supraclavicular node conf
irmed recurrence of breast cancer.
