* Lymphocytic inflammation is a diffuse chronic ongoing inflammation.
* Seen in:
*# Diseases of the central nervous system.
*#* Lymphocytes appear microscopically as several layers of cells around blood vessels in the perivascular space.
*#* They indicate that there is damage to the nervous tissue further in.
*#** Should alert to the possibility of viral infection, which is a common cause of central nervous system disease.
*#*** E.g. louping ill.
*# The gut.
*#* An excessive number of lymphocytes diffusely infiltrating the lamina propria, often in conjunction with plasma cells, indicate an ongoing non-specific chronic enteritis.
*# The respiratory tract.
*#* Peribronchial and peribronchiolar cuffing may occur to the point of actual lymphoid follicle formation in these areas.
*#** Follicles are sometimes large enough to cause partial occlusion of the airways.
*#* A feature of some chronic lung diseases.
*#** Ee.g. [[:Category:Mycoplasmas|Mycoplasmosis]] in swine and calves.
