For other types of lymphoma affecting dogs the clinical signs will demonstrate the anatomical site affected.

For other types of lymphoma affecting dogs the clinical signs will demonstrate the anatomical site affected.

'''Mediastinal''' forms will present with dyspnoea due to compression of the trachea and upper respiratory tract. Dysphagia may also be present due to compression of the oespohagus. Dogs with mediastinal lymphoma can also have pitting [[Oedema|oedema]] of the head and neck due to compression of the cranial vena cava. On ausculatation there is often an absence of lung sounds cranially and caudal displacement of the normal cardiac sounds, and dullness on percussion of the cranial thorax. Polyuria and polydypsia may be present due to paraneoplastic hyperlcalcaemia. Differential diagnoses for a cranial mediastinal mass are: thymoma, thyroid adenocarcinoma, a mediastinal abscess, or a branchial cyst.

'''Mediastinal''' forms may present with dyspnoea due to compression of the trachea and lungs. Dogs with mediastinal lymphoma can also have pitting [[Oedema|oedema]] of the head and neck due to compression of the cranial vena cava, called caval syndrome. On ausculatation there is often an absence of lung sounds cranially and caudal displacement of the normal cardiac sounds, and dullness on percussion of the cranial thorax. Polyuria and polydypsia may be present due to paraneoplastic hypercalcaemia. Differential diagnoses for a cranial mediastinal mass include: thymoma, thyroid adenocarcinoma, a mediastinal abscess, or a branchial cyst.

'''Alimentary''' forms will present with signs of obstruction such as [[Vomiting|vomiting]], [[Diarrhoea|diarrhoea]], anorexia and thickened loops of intestine on abdominal palpation.

'''Alimentary''' forms may present with signs such as [[Vomiting|vomiting]], [[Diarrhoea|diarrhoea]], anorexia and thickened loops of intestine or mass lesions on abdominal palpation.

'''Cutaneous''' lymphoma can also occur with a varied presentation but often present as cutaneous nodules.
