Umbilical metastasis derived from breast cancer: report of a case

Umbilical metastases mainly arise from malignancies of the digestive and gynecological systems, but rarely from breast cancer. A 64-year-old woman with a history of breast cancer was referred to us for investigation of a painful lesion in the umbilicus. Immunohistochemical staining of a specimen obtained by biopsy from the nodule showed umbilical metastasis of breast cancer. After a work up, she was successfully treated with a combination of surgery and endocrine therapy. We report this case to reinforce that not all periumbilical tumoral deposits are consistent.
