What's the difference between extravasation and infiltration?

Extravasation


Definition:

  • (n.) The act of forcing or letting out of its proper vessels or ducts, as a fluid; effusion; as, an extravasation of blood after a rupture of the vessels.

Infiltration


Definition:

  • (n.) The act or process of infiltrating, as if water into a porous substance, or of a fluid into the cells of an organ or part of the body.
  • (n.) The substance which has entered the pores or cavities of a body.

Example Sentences:

  • (1) Patients with papillary carcinoma with a good cell-mediated immune response occurred with much lower infiltration of the tumor boundary with lymphocyte whereas the follicular carcinoma less cell-mediated immunity was associated with dense lymphocytic infiltration, suggesting the biological relevance of lymphocytic infiltration may be different for the two histologic variants.
