| |
| − | *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
| |

| |
| − | * 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
