Urinary Bladder - Mineralization
comment:Mineralization occurs as densely basophilic, granular material ( Figure 1 and Figure 2 ). It usually involves the muscle wall of the urinary bladder. Dystrophic mineralization may be seen secondary to a variety of causes, especially in areas of necrosis. Metastatic mineralization is uncommon in the rodent bladder.
recommendation:Mineralization should be diagnosed and given a severity grade when seen in the absence of other lesions (e.g., metastatic mineralization) or, if it is secondary to another process (e.g., dystrophic mineralization), when it is a significant component of the lesion.
