The aetiology is thought to be immunological due to the increased immunoglobulin level in the blood. The Plasmacytic Stomatitis diagnose can only be differentiated from other lesions by histopathology. ...
متن کاملEstimating Age in Dogs and Cats Using Ocular Lens Examination
Nuclear sclerosis increases the refractivity of the ocular crystalline lens as animals get older. This increased refractivity causes the two pinpoint lens reflections seen in the eyes of young adult dogs and cats to appear to increase in size. Increasing refractivity also causes the clear lens nucleus to develop a faint blue–gray appearance that becomes increasingly intense. When categorized, t...
متن کاملOcular Surface Squamous Neoplasia
The ocular surface is composed of the conjunctiva and the cornea. The conjunctiva is a mucous membrane which covers the globe and inner part of the eyelids. The morphology of conjunctival epithelial cells are nonkeratinized stratified epithelia which vary from cuboidal over the tarsus, to columnar in the fornices, to squamous epithelia on the globe. Goblet cells account for up to 10% of the bas...
متن کاملOcular melanocytic neoplasia.
Tumors of melanocytic origin in ocular tissues are relatively uncommon in dogs and cats, and although many are benign, some have a high potential for metastasis. In addition, even small ocular masses can be significant due to their potential vision-threatening sequelae. Such tumors may occur on the eyelids, on the conjunctival surface, along the limbus, or within the uveal tract. While several ...
متن کاملPancreatitis in Dogs and Cats
The fundamental mechanism of disease in pancreatitis is autodigestion of pancreatic tissue by digestive enzymes that are prematurely activated within the pancreatic acinar cells. Normally, pancreatic digestive enzymes are released from the pancreas as inactive precursor zymogen granules. Trypsinogen within these granules is proteolytically cleaved and activated when it reaches the duodenal lume...
