Objective: To compare the use of Papanicolaou and Wright-Giemsa stains for the evaluation of body fluids in cytology and hematology laboratories and determine whether other factors account for discrepancies in diagnosis.
Study Design: We retrospectively reviewed cytopathology reports of peritoneal, pleural, and cerebrospinal fluids received by hematology and cytology laboratories for 1 year. Cases were divided into 3 categories-benign, atypical, and malignant--and slides of discrepant diagnoses were reviewed.
