Abstract
Behcet's disease is a systemic, chronic recurrent disease characterized by oral aphtha, genital ulcers, ocular lesions, and arthritic symptoms. Incomplete Behcet's disease lacks these common symptoms. We report a case of incomplete Behcet's disease associated with severe trismus.
The patient was a 39-year-old man. Initially, severe trismus developed, accompanied by swelling of the right cheek anthema-like folliculitis, and pharyngitis. Inflammatory symptoms with fever also occurred.
Treatment for trismus was administered to relieve the main symptoms, and collagen disease specialists conducted medical examinations. Incomplete Behcet's disease was finally diagnosed.
Steroid treatment was extremely effective. After 35 days of steroid treatment, the trismus totally resolved. The anthema-like folliculitis was suggested to be caused by inflammation of the masticatory muscles or temporomandibular joint due to Behcet's disease. It was difficult to diagnose this case as incomplete Behcet's disease.
