Sarcoidosis and foreign body reactions are common differential diagnoses of skin granuloma formation. We report a 40 year –old man with sarcoid type granulomas containing polarized foreign materials, and also bilateral hilar adenopathy. It appears that detection of foreign bodies in histopatologic studies of granulomas does not necessarily exclude the possibility of sarcoidosis.

Intraneural interfaces are stimulation/registration devices designed to couple the peripheral nervous system (PNS) with the environment. Over the last years, their use has increased in a wide range of applications, such as the control of a new generation of neural-interfaced prostheses. At present, the success of this technology is limited by an electrical impedance increase, due to an inflamma...

Foreign body reaction is a rare complication after cochlear implantation. When such complications do occur, they may be intractable and difficult to be cured with antibiotics or surgical revision that may lead to cochlear reimplantation finally. In this article, we presented a patient with foreign body reaction who recovered well after cochlear reimplantation and has been in good health through...
