Serous effusions are a well-recognized complication of lymphoma but rarely the detection of lymphoma cells in a serous effusion has been the first morphologic manifestation of the disease .
Staining methods 1.papanicolaou method 2. Air-dried Romanowsky stained preparation
Papanicolaou stained preparations do not allow the same degree of correlation with the various types of lymphoma and leuk- emia that can be achieved by the use of Romanowsky-stained preparations.
However ,not being able to type lymphoma in serous effusions is rarely a disadvantage of pap method ,because nearly all of the patients has already been diagnosed as having lymphoma .
Key features of lymphoma and leukemia 1. Isolated cell only 2. Cells frequently necrotic 3. Morphologic range : from seemingly mature lymphocyte to large cells with polymorphous nuclei
