Salivary Gland, Duct - Concretion - Gallery

Image of concretion in the salivary gland duct from a female F344/N rat in a subchronic study
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.
