Synovial cysts of the jaw joint (TMJ) are exceptional. Dr Serge Ketoff, senior author, reports this rare case published in the Journal of Rheumatology, useful for the differential diagnosis of peri-articular masses.
In brief
- TMJ synovial cyst is a very rare cause of preauricular swelling.
- It should be known for the differential diagnosis of masses in this region.
- Case documented with imaging and surgical management.
A rare but instructive case
A synovial cyst of the temporomandibular joint is an exceptional entity. Faced with preauricular swelling, it broadens the range of diagnoses to consider, alongside more common parotid, tumoral or articular conditions.
Relevance for practice
Recognising this lesion relies on imaging and clinical–anatomical correlation. This case highlights the importance of thorough assessment before any procedure, at the interface between maxillofacial surgery and rheumatology.
Key points
- Exceptional TMJ entity.
- Consider it for a preauricular mass.
- Interface of maxillofacial surgery / rheumatology.
