infiltration

 [in″fil-tra´shun]
1. the pathological accumulation in tissue or cells of substances not normal to them or in amounts in excess of the normal.
2. infiltrate (def. 2).
3. the deposition of a solution directly into tissue; see infiltration anesthesia.
adipose infiltration fatty infiltration.
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.

cel·lu·lar in·fil·tra·tion

migration of cells from their sources of origin, or direct extension of cells as a result of unusual growth and multiplication, thereby resulting in fairly well-defined foci, irregular accumulations, or diffusely distributed individual cells in the connective tissue and interstices of various organs and tissues; used especially with reference to such changes associated with inflammations and certain types of malignant neoplasms.

cellular infiltration

the migration and grouping of cells, especially blood cells, within tissues throughout the body.

cellular infiltration

A nonspecific term for extension, permeation or migration of cells from a point of origin, which occurs in two different contexts:
(1) Infiltration by malignant cells that are normally confined to a particular site (metastasis is more specific and appropriate); and
(2) Infiltration by inflammatory cells that are by definition mobile and heed a local clarion call to arms (inflammatory infiltration is a better term).

Migration of cells from their sources of origin, or direct extension of cells as a result of unusual growth and multiplication; used especially with reference to such changes associated with inflammations and certain types of malignant neoplasms.

cellular infiltration

1. The movement of inflammatory white cells into tissue.
2. The movement of cancer cells into a tissue.

infiltration

the diffusion or accumulation in a tissue or cells of substances not normal to it or in amounts in excess of the normal; also, the material so accumulated.

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.
