title: Plasmacytoma of the breast. Unusual initial presentation of myeloma: report of two cases and review of the literature.
abstract: Two patients who presented initially with breast masses proven to be plasmacytomas, are described. In both cases the breast masses led to the diagnosis of multiple myeloma, which was retrospectively already present at the time of the breast biopsy. One patient with IgG lambda-type myeloma developed plasma cell leukemia and amyloidosis and failed to respond to radiochemotherapy. The second patient was in complete remission, four years after therapy, but has subsequently relapsed and died. All cases of breast plasmacytoma, described in the medical literatures are reviewed, and guidelines for future therapy are suggested.
