Primary non-secretory plasma cell leukemia with atypical morphology - a case report

Only one case of primary non-secretory plasma cell leukemia with atypical morphology has been reported thus far. Here we report another such case of plasma cell leukemia diagnosed on fl ow cytometry, as morphological heterogeneity and lack of monoclonal immunoglobulins in both serum and urine, made it difficult to come to a conclusive diagnosis based purely on morphology.
