Table 3. Comparison of percentage of regressing vessels between follicles and paracortex in reactive hyperplasia and follicular lymphomas (paired samples t-test).
| Follicles % regressing vessels | Paracortex % regressing vessels | P-value | ||
|---|---|---|---|---|
| Reactive, nodes only (11) | 9.0 | vs | 0.2 | =0.021 |
| Reactive, nodes and tonsils (16) | 10.4 | vs | 2.1a | =0.010 |
| Follicular NHL all (21) | 10.1 | vs | 0.2 | <0.0009 |
a
The high value reported in the paracortex of reactive tonsils is because of a single case of reactive tonsil in which 24% of the paracortical vessels showed signs of regression.
