Case in brief
A 40-year-old woman with psoriasis and familial Mediterranean fever developed progressive restriction of mouth opening. Clinical examination and imaging confirmed fibrous ankylosis of the right temporomandibular joint. Symptoms progressed despite multiple arthrocentesis procedures and conservative treatment, and she ultimately underwent open joint surgery and arthroplasty.
What made this case unusual
The report describes fibrous TMJ ankylosis in a patient with coexisting psoriasis and familial Mediterranean fever, an overlap the authors identify as previously undocumented.
Diagnostic / clinical pearl
In patients with systemic inflammatory diseases, progressive limitation of mouth opening warrants assessment for TMJ involvement, including ankylosis.
Why it matters
Overlapping autoimmune and autoinflammatory conditions may complicate diagnosis and management of joint disease, including at the TMJ.
