Abstract
We review here 15 patients with cutaneous malignant melanomas metastatic to the breast. All but one were premenopausal females with a median age of 38 years. Most patients had a primary lesion on the upper extremities or trunk (80%), with only one patient having a lower extremity primary. The median interval between diagnosis of the primary and breast involvement was 33 months, with one patient developing breast involvement 11 years later, at the time of her second pregnancy. Five patients had bilateral breast involvement, and all had other sites of metastases at the time of diagnosis. The median survival after diagnosis of breast metastases was 10 months, portending a poor prognosis.
