2. infiltrate (def. 2).
3. the deposition of a solution directly into tissue; see infiltration anesthesia.

calcareous infiltration deposit of lime and magnesium salts in the tissues.
cellular infiltration the migration and accumulation of cells within the tissues.
fatty infiltration
1. a deposit of fat in tissues, especially between cells.
2. the presence of fat vacuoles in the cell cytoplasm.
intravenous infiltration
1. the movement of a needle or cannula from within a vessel into the surrounding tissue. The typical symptoms are a slowed flow of fluids, swelling, pallor, coolness of the skin, and discomfort in the area; severity of the symptoms will depend on the amount and type of fluid infused.
2. inadvertent administration of parenteral fluid into the tissues.
