Objective.

Multiple extramedullary plasmacytoma lesions involving subcutaneous tissue, breast, mediastinal tissue, spleen, and soft tissue of pelvic region along with multiple bones plasmacytomas without marrow plasmacytosis are a very rare presentation.

Design.

Case report.

Result.

A 54-year-old female was found to have multiple small bony lytic lesions, multiple extramedullary soft tissue plasmacytomas, serum M protein >3 g/dL, and elevated ESR.

Bone marrow aspirate did not reveal any evidence of multiple myeloma/plasmacytosis.

There was no anemia, hypercalcemia, or renal insufficiency.
