Comparison of blood and tissue eosinophilia in Hodgkin's disease.

“A”: Cases with few eosinophils (< 5% of surrounding cells, no clusters); “B 1”: cases with moderate eosinophilia (5%-15% of surrounding cells or clusters of eosinophils); “B 2”: cases with strong eosinophilia (> 15%). For each group, the diagram shows the highest and lowest values of blood eosinophil count (horizontal bars), the interquartile range (box) in which the middle 50% of values lie, and the median (horizontal line in box). The grouping shows a borderline significance when correlated with the amount of blood eosinophils. Y-axis: Eosinophils in blood (thousand per μL).
