Salivary Gland, Duct - Concretion

    Narrative
    Salivary gland, Duct - Concretion in a female F344/N rat from a subchronic study. The relatively large concretion (arrow) is obstructing and expanding a salivary duct.
    Salivary gland, Duct - Concretion in a female F344/N rat from a subchronic study (higher magnification of Figure 1). The concretion became fragmented during processing.
    Salivary gland, Duct - Concretion in a male B6C3F1 mouse from a subchronic study. There is a basophilic concretion (arrow) in a salivary duct.
    Salivary gland, Duct - Concretion in a male B6C3F1 mouse from a subchronic study (higher magnification of Figure 3). The concretion is eliciting a chronic inflammatory response around the duct with fibrosis.
    Salivary gland, Duct - Concretion in a female F344/N rat from an acute study. There is a basophilic concretion (arrow) in a salivary duct.
    Salivary gland, Duct - Concretion in a female F344/N rat from an acute study (higher magnification of Figure 5). The concretion is eliciting a chronic inflammatory response around the duct with fibrosis.�
