Once ruptured, the exposed pigments cause a foreign body reaction and inflammation.

If left embedded the mouthparts cause a foreign body reaction and are usually eventually sloughed like a splinter.

This research involves producing a coating that is very much like biologic material in order to further lessen the foreign body reaction.

However, these polymers are often associated with foreign body reaction; implant failure; and hernia recurrence (over 42%).

Potential problems: Foreign body reactions, rarely with infection or erosion of scrotal skin, are minimal but constitute the most significant complication.

The biomaterial is completely reabsorbed in 6 months and can be seen only a minimal foreign body reaction tissue in the vicinity of the implant.

It is presumed that ivalon injected to plug the liver biopsy leaked intraperitoneally and caused the foreign body reaction seen.

On the other hand, studies have shown the disadvantages of using PDS: no osteogenic properties, foreign body reactions, etc.

With respect to implant materials, chronic inflammation and foreign body reactions are associated with the development of a fibrous capsule around the implant.

As with other aesthetic procedures, possible complications of the procedure can include infection, hematoma, discomfort, anatomic asymmetry, or foreign body reaction (called granulomas).

Common misdiagnoses include fungal and parasitic infection, cellulitis, skin tuberculosis, rheumatoid arthritis, foreign body reaction, and skin tumor.

They have recently been reported as helpful treatment for pilonidal cysts, since they eliminate the ingrown hairs that produce the troublesome foreign body reactions in this malady.

Biologic mesh originates from the need of a material addressing the problems associated with permanent synthetic mesh, including chronic inflammation and foreign body reaction, stiffness and fibrosis, and mesh infection.

British ophthalmologist Sir Harold Ridley observed that Royal Air Force pilots who sustained eye injuries during World War II involving PMMA windshield material did not show any rejection or foreign body reaction.

It was shown that macrophages joined to form multinucleated giant cells and then produced a well-circumscribed area of tissue reaction, not unlike the granulomatous tissue reactions of a typical foreign body reaction, and persisted for up to 8 months.

The lesion is in some cases very difficult to distinguish from breast cancer and other causes such as infections (tuberculosis, syphilis, corynebacterial infection, mycotic infection), autoimmune diseases (sarcoidosis, Wegener's granulomatosis), foreign body reaction and granulomatous reaction in a carcinoma must be excluded.
