Abstract
Summary
The diagnosis of thoracic neoplasia in the horse can be difficult
due to the nonspecific nature of the clinical signs and their
overlap with other pulmonary diseases. Haematological and
serum biochemical evaluation, thoracic ultrasonography,
radiography, endoscopic examination, and, where
appropriate, thoracocentesis and pleural fluid cytology may
all be helpful in reaching a diagnosis. Granular cell tumours
are the most frequently reported primary pulmonary tumours of
horses. They occur as single or multiple masses adjacent to
bronchi and bronchioles, and the mass typically extends into
the airway, resulting in partial or complete occlusion of the
lumen. Thymic tumours are classified as benign or metastatic,
based on evidence of tissue invasiveness, even though they
uniformly appear benign histologically. These tumours are
derived from epithelial reticular cells of the thymus and are
rare in horses. Other primary thoracic neoplasms originate
from various pulmonary tissues and are primarily reported as
single case reports: pulmonary and bronchial carcinoma and
adenocarcinoma, bronchogenic squamous cell carcinoma,
bronchial myxoma, pulmonary chondrosarcoma, pulmonary
leiomyosarcoma and pleuropulmonary blastoma. Clinical
signs of these primary pulmonary neoplasms are dependent
on the tumour type and location, but commonly include
chronic cough, weight loss, anorexia, fever and respiratory
difficulty; ventral oedema, pleural effusion and epistaxis are
also frequently observed. Mesothelioma
