[Double breast and vertebral plasmacytoma. Acute myeloblastic leukemia 8 years later]

We report in a 40 year-old woman a bifocal mammary and vertebral plasmocytoma attended by surgery and "preventive" chemotherapy. Eight years later, an acute and apparently non secondary myeloblastic leukemia is observed without sign of diffuse myelomatosis. Plasma cell tumors of the breast are uncommon. Eleven cases have been published, combining solitary plasmocytoma and infiltration occurring in multiple myeloma.
