The objective of the present study is to highlight the spectrum of cytomorphology, immunophenotype, and cytogenetics in leukemic serous effusions (LSE).<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials<\/jats:title><jats:p>Present study is retrospective and descriptive. We reviewed all the SE, which were reported as suspicious or positive of leukemic infiltration from 2016 to 2019 for cytomorphological features. CSF and effusions involved by lymphomas were excluded. Cyto\u2010diagnosis was compared with primary proven diagnosis (by ancillary techniques) and disconcordant cases were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Out of total 9723 effusions, only 0.4% (n\u00a0=\u00a040) showed leukemic involvement and included nine cases of AML, three of B\u2010ALL, 13 T\u2010ALL, 2 MPAL, 6 CML, 5CLL, one each of chronic myelomonocytic leukemia and AML with myelodysplasia. The most common site of involvement was the pleural cavity (n\u00a0=\u00a030), followed by the peritoneal cavity (n\u00a0=\u00a07) and the pericardial cavity (n\u00a0=\u00a03). T \u2010ALL (41.9%) was the most common leukemia involving pleural fluid followed by AML (23.3%). CML (42.8%) was the most common leukemia involving the ascitic fluid followed by B\u2010ALL (28.6%). Accurate diagnosis was given on cytomorphology in 72.5% (29\/40) cases and 15.0% (6\/40) were reported as non\u2010Hodgkin lymphoma.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Cytology is an effective tool available to make a diagnosis of LSE.
