giant cell reaction

Any reparative tissue reaction with multinucleated epithelioid histiocytes that may be due to exogenous material (e.g., sutures) or endogenous material (e.g., the contents of a ruptured epidermal inclusion cyst, chalazion or fat)

This is the primary reason that UMWPE wear debris and related foreign-body giant cell reaction can be associated with hip prostheses but is not seen with the TMJ Concepts metal-on-UMWPE prostheses (30, 31).
In hip prostheses, particularization of UMWPE and polymethylmethacrylate, a bone cement, can cause a foreign-body giant cell reaction and bone lyses related to the relatively large size of the particles created by wear (32-34).

These cells surrounded stalks of stroma that contained blood vessels with foamy histiocytes, extensive hemorrhage, ischemic necrosis, and foreign body giant cell reaction to cholesterol (Figures 2 and 3).
Infrequently, clusters of epithelioid cells with a giant cell reaction may also be encountered within RLH lesions.
It is possible that the eggs released from the proglottids of the adult worm entered the lumen of the appendix when the patient had acute appendicitis, and ulceration of the mucosa allowed egress of the eggs into the wall, where they incited a foreign body-type giant cell reaction.
In particular, there was no associated fibrosis and giant cell reaction.
The histologic differential diagnosis of postherpetic granuloma annulare includes idiopathic granuloma annulare; sarcoidosis; foreign-body-type giant cell reactions, such as to silica, zirconium, beryllium, and tattoo pigments (most commonly to red); metastatic Crohn disease; and infections such as tuberculoid leprosy and tuberculosis.
