A case of temporomandibular joint arthritis with psoriasis vulgaris

Abstract

Psoriasis vulgaris is known as a systemic cutaneous disease. Baker et al. reported 4 cases of arthritis of the TMJ complicated with psoriasis in 53 cases. It is said that clinical signs of psoriatic arthritis are similar to that of rheumatoid arthritis. Some cases have deviation of the mandibular movement and disturbanee of the mouth opening due to destruction of the condylar head. Others have pain and tenderness of the TMJ region due to erosion and flattening of the condylar head. However, there have been few reports of psoriatic arthritis of the TMJ in Japan.
