hemosiderotic synovitis

Saturday 16 December 2017

Definition: Hemosiderotic synovitis is associated with hemophilia and intra-articular bleeding.

There is no mononuclear or giant cell nodular cellular proliferation. Hemosiderin is primarily found in synovial lining cells.

Localised- and diffuse-type tenosynovial giant cell tumours (TGCT) are regarded as different clinical and radiological TGCT types. However, genetically and histopathologically they seem indistinguishable.
