  −
* Seen in:

*# Diseases of the central nervous system.

  −
*#* 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.
