I'm working on/reading a scientific article about the use and effects of Corticosteroid or Ketorolac on rabbit tendons and I got stuck at infiltration in the following excerpts:
"Despite the increased adhesion formation noted grossly, minimal differences in lymphocytic/plasmacytic infiltration, focal histiocytic infiltration were noted between the (...) groups"
"Tendon specimens were analyzed for evidence of necrosis, lymphocytic/plasmacytic inflammatory infiltration, focal histiocytic inflammation, and vascularity."
I found in medical dictionaries that infiltration is " the pathological diffusion or accumulation in a tissue or cells of substances not normal to it" but this definition is similar to neoplasia's (according to The Free Dicitionary, "an abnormal new growth of tissue; abnormal proliferation of benign or malignant cells").
Does someone know if they can be synonyms?
