She had a left mastectomy with lymph node sampling performed 5 years before for infiltrating ductal carcinoma that was estrogen receptor positive. She had back pain and shoulder pain that was dull but constant. This is metastatic breast carcinoma. Growth of the tumor can produce reactive new bone that appears denser and brighter on radiographs. The black colour is typical for metastatic melanoma.
Melanomas tend to metastasize widely.
These are osteoblastic metastases in which considerable new reactive bone is being induced by the growth of the tumor. Prostatic adenocarcinomas can metastasize to bone and produce this pattern.
