Micronucleus and Its Significance in Effusion Fluids.

Background: Micronucleus (MN) is an extranuclear body within the cell formed due to failure of incorporation of whole chromosomes or their fragments during cell division. MN scoring can be done to identify malignant effusions.

Aims: This study aimed to score micronuclei to distinguish malignant effusion from benign effusions and to correlate MN score with type of malignant effusion.
