颞下颌关节区的关节外弥漫性色素沉着绒毛结节性滑膜炎在临床上极为罕见,作者报道1例,并结合文献复习本病的临床特征、诊断及治疗。认为本病在MRI上有特征性表现,可确诊。治疗以手术为主,应广泛切除肿块周围组织包括关节囊、滑膜等,术后辅以放疗。

Diffuse pigmented villonodular synovitis （PVNS）in the temporomandibular joint（TMJ） is distinctly rare. This article reported a case of extra-articular type of PVNS of the TMJ, and reviewed the previously reported cases in the literature. It is concluded that PVNS can be diagnosed by characteristic MRI finding, wide local excision including a total synovectomy and postoperative radiotherapy should be adopted.
