Intra-Articular Pigmentation of Synovium: An Unusual Cause.

Intra-Articular Pigmentation of Synovium: An Unusual Cause. Clin Orthop Surg. 2016 Sep;8(3):330-2 Authors: Verma S, Hamilton S, Liew SM Abstract An unusual grayish brown discoloration of the synovium was found during a knee arthroscopy of a 72-year-old man. He also had similar pigmentation affecting the skin on the legs, arms, hands, and face. It was found he had been taking 400 mg of amiodarone hydrochloride daily for last 7 years. Amiodarone is known to cause a slate grey pigmentation of skin and cornea, but we believe this is the first report of amiodarone-induced pigmentation of the synovium. The arthroscopist should be aware of the possibility of drug-related synovial pigmentation and include this in differential diagnosis. PMID: 27583118 [PubMed - in process]
