proliferative lesions include epithelial cell hyperplasia,
fibrosis, focal lymphocytic infiltration and macrophage
aggregates. An indication of inflammation or infection can
be recorded as perivascular cuffing (Fig. 4.7).
The increase in size of individual cells is termed
hypertrophy and can be attributed to increased work load,
while physical, chemical irritation or infections, can lead to
an increase in number of cells in a tissue, termed hyperplasia.
