− | * 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.
