| What is the pathogenesis of this condition? | An ascending foreign body, in this case a grass awn, is usually the cause of a single sialolith within a salivary duct. The sialolith consists of concentric layers of mostly calcium phosphate crystals around the organic nucleus. They are usually elongated in shape. In the dog and cat, dystrophic calcification of inspissated saliva in salivary mucoceles may also result in sialolith formation; in these cases, multiple small sialoliths may be present. A single, large sialolith located in a salivary duct may give rise to some retention of saliva but is generally believed not to cause a salivary mucocele. |
