Malignant Mesothelial Cells In Pleural Fluid

The distinction between reactive and malignant mesothelial cells has long been a challenge in effusion cytology. Mesothelial cells are found in variable numbers in most effusions but their presence at greater than 5 of total nucleated cells makes a diagnosis of tb less likely.
