High power view of a deposit of multiple myeloma in bone

High power view of a deposit of multiple myeloma in bone •A higher power view of a deposit of malignant melanoma in bone marrow. •Some of the typical, mature adipocytes of bone marrow are seen in this field. •Most of the other cells in this image however, resemble each other. •A typical cell can be seen at the tip of the black pointer. •It is a large cell, with a nucleus that is placed at one end of the cell. •The cytoplasm is abundant and stains blue (ie. basophilic). •A paler relatively understained area is seen near the nucleus. •These features typify a plasma cell. •Careful examination of this field reveals that most of the cells in this field resemble that cell. •Malignant melanoma is a tumor of plasma cells that arises usually in the bone marrow.
