Severe granulomatous reaction associated with hypercalcemia occurring after silicone soft tissue augmentation of the buttocks: a case report.

UNLABELLED: Liquid silicone is a permanent filler. Its use to augment soft tissues for aesthetic purposes was widespread worldwide in the 1960s. Although initially considered to be biologically inert, this substance may cause, after its injection, an inflammatory granulomatous effect of variable severity and, in very rare cases, a severe hypercalcemia, which can be life threatening. The reported case highlights the well-known physiopathology of hypercalcemia, and the various therapeutic options are discussed.
