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

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.

A large number of them were able to complete their development although some dead ones were present surrounded by cellular infiltration. Moderate generalized diffuse cellular infiltration was present in the tissues and in between the organs.
Bone marrow was hypercellular with marked megakaryocytic hyperplasia, but no evidence of fibrosis or cellular infiltration. Skin biopsy revealed subepidermal blister with PAS- positive material deposited in the upper dermis in a perivascular and periadnexal distribution (Figure 2).
Cellular infiltration had clearly decreased for the cross-linking matrices, with and without attached glycosaminoglycans.
This was reflected in better liver function tests and decreased signs of tissue damage and inflammatory cellular infiltration in diseased organs.
Skin biopsy showed dense lichenoid cellular infiltration in the papillary dermis.
SMU crystals can induce a rapid and intense inflammatory cellular infiltration, with a prominence of neutrophils in a subcutaneous cavity (air pouch), with a pattern similar to the inflammatory cell infiltrate seen in patients with acute gouty arthritis (20).
The superficial dermis showed segmentar zones of oedema, cell proliferation, ectasia, vascular congestion and mixed-type angiocentric cellular infiltration, mainly lymphocytes, macrophages and plasma cells (Figure 2).
