Cytologic and Immunophenotypic Features of Malignant Cells in Pediatric Body Fluids.

Objective: Cytospin preparations and immunocytochemistry are common methods in hospitals to evaluate malignancies in body fluids. Characteristics of malignant cells in pediatric body fluids have not been adequately evaluated.

Study Design: 183 pleural, peritoneal and pericardial pediatric fluid specimens were examined by cytospin preparations and immunocytochemistry from two hospitals using similar procedural techniques.
