Breast Metastasis as a Presentation of Malignant Melanoma.

The majority of malignant breast lesions are primary tumors originated from breast tissue. These primary breast cancers usually metastasize to lymph nodes, lungs, bones and brain. Metastases from cancers of other organs to the breast are very rare, but have been encountered in patients with malignant melanoma, carcinoid tumors or lung carcinoma.
