==Description==

Oesophageal neoplasia is very rare, accounting for less than 0.5% of all neoplasia in dogs.  It has a higher incidence in the areas where ''Spirocerca lupi'', a [[Helminths|helminth parasite]], is endemic in Africa and the south-eastern USA.  The most commonly reported forms of neoplasm are:

Oesophageal neoplasia is very rare, accounting for less than 0.5% of all neoplasia in dogs.  It has a higher incidence in the areas where ''Spirocerca lupi'', a [[Helminths|helminth parasite]], is endemic in Africa and the south-eastern USA.  The most commonly reported forms of neoplasm are:

*'''Squamous cell carcinoma''' - usually apparent as an annualar thickening in the middle third of the oesophagus, anterior to the heart base.

*'''Squamous cell carcinoma''' - usually apparent as an annualar thickening in the middle third of the oesophagus, anterior to the heart base.

This is often poor as the disease is usually in its advanced stages at the time of diagnosis, leaving few options for surgical management.  In addition, the metastatic rate of oesophageal tumours is high with local invasion and spread to draining lymph nodes (cervical and prescapular nodes from the cervical oesophagus and mediastinal nodes from the thoracic oesophagus) and to distant organs.
