Back to Inflammation - Pathology

Diseases Involving Reactive Node Diseases

the Lymphocytes Parasitising Diseases

organism grows in the lymphocytes and ruptures them
if large infecting dose

- may be rapidly fatal since animal may no tb e able to mount an immunological attack

if smaller infecting dose

- loss of mature lymphocytes causes a dramatic stimulation of the remaining lymphocyte precursors

- node hyperplasia follows

- competition between lymphocytolysis by the organism and lymphocyte production by the nodes

- clinically

- may be swelling of the node at one stage and reduction in size at another

canine distemper

virus

swine fever

virus

bovine east coast fever

protozoan

Leishmaniasis in the dog

-===Lymph node pigmentation===
-*Lungs
-:- anthracosis
-::- carbon derived from soot finds its way to the local nodes in macrophages
-*Skin
-:- dermatopathic lymphadenopathy or melanic reticulosis
-::- in pigmented animals, especially black dogs
-::- chronic inflammatory skin conditions lead to melanin deposition in hyperplastic nodules
-:-  also occurs in nodes draining skin melanomas where the pigment may be  the result of skin ulceration or secondary tumour deposit
-::- these two should not be confused since the prognosis is very different following surgery
-===Emphysema===
-*interstitial emphysema
-:- common in cases of dyspnoea
-:- more commonly affects bovine lung
-::- due to well developed pulmonary lobulation and hence much loose interstitial lung tissue
-*collection of gas bubbles in bronchial and mediastinal lymph nodes
-:- gas travels to these nodes after gaining entry to the many lymphatic vessels present in the interstitial tissue
-===Neoplasia===
-* Primary tumours
-** Lymphosarcoma (lymphoma)
-:-  of lymphoid cells with lymph node enlargement
-:- smooth, pale hemogenous but may have areas of necrosis
-:- may cause [[Parathyroid Glands - Pathology#Pseudo-Hyperparathyroidism|pseudo-hyperparathyroidism]]
-* Secondary tumours
-:- nodes often involved in the spread of tumours by extension or metastasis
-:- usually carcinomas
