1 Introduction In acute leukemias (ALs) with extreme hyperleukocytosis (> 100 × 109/L), also referred to as hypercellular AL, cytoplasmic fragments of blasts—often termed pseudoplatelets—can be mistakenly counted as platelets by impedance. This occurs due to their small size [1-9], which typically ranges from 2 to 30–40 fL, depending on the analyzer.

Macroscopic examination revealed six flat, white tumors scattered along the jejunum and ileum, ranging in size from 5 to 9 cm, with a perforation present in the ileum.
