Comparison of sizes and shapes of tumor cells in plasma cell leukemia and plasma cell myeloma.
Thirteen cases of plasma cell leukemia and 13 cases of nonleukemia plasma cell myeloma were compared with respect to the sizes and shapes of tumor cells in marrow smears. It was demonstrated that the leukemia cells were elongated or ovoid and significantly smaller in size, whereas the myeloma cells were generally more nearly round and larger.
