Encyclopedia entry (1928–1936)
MIGRATION (from the Latin migro- I wander), a term frequently used in theoretical and practical medicine to indicate the wandering or shifting of a given pathological process from one part of an organ to another or from one organ to another. Thus, one speaks of migratory pneumonia when inflammatory foci capture new areas of the lung parenchyma, of migratory erysipelas, of migratory thrombophlebitis, and so on. By M. of cells is meant all that is contained in the term wandering cells (see). Depending on whether the M. of cells proceeds along the lumen of the vessel or back from the vessel beyond its limits, one speaks of immigration or emigration. One also speaks of M. of parasites, for example, of the larvae of helminths (see Human Helminthoses).
