Salivary Gland, Duct - Concretion
comment:Concretions (mineralization of material in the ductular lumen) occur infrequently but are most commonly seen in older animals as a background lesion. They may be seen with atrophy. Concretions or foreign bodies can lead to duct dilation, inflammation, and fibrosis.
recommendation:A concretion in a salivary duct should be diagnosed whenever present. They need not be graded unless grading would divulge a treatment effect. Secondary lesions, such as dilation, inflammation, and fibrosis, need not be diagnosed separately unless warranted by severity.
