Chondroid tenosynovial giant cell tumour : a rarity in the temporomandibular joint

Tenosynovial giant cell tumours of the temporomandibular joint (TMJ) are extremely rare, particularly the subset of chondroid tumours. They can be broadly divided into localised and diffuse types, of which we know of only 116 reported cases in the TMJ. Rarer still are the subset of chondroid tenosynovial giant cell tumours, of which we know of only 30 cases that have affected the TMJ. We present a case that involved the TMJ, and include a discussion of its management.
