Pigmented villonodular synovitis (PVNS) is a proliferative disorder that affects synovium-lined joints, bursae, and tendon sheaths. It appears in both diffuse and localized forms, depending on the extent of synovial involvement. PVNS rarely involves the temporomandibular joint (TMJ); when it does, it manifests clinically as a slowly growing and painless preauricular mass that resembles a parotid tumor. TMJ dysfunction, paresthesia, and/or hearing loss can result. We present a case of a large extra-articular PVNS of the TMJ, and we review the literature.
色素沉着绒毛结节性滑膜炎(PVNS)是一种增殖性疾病,可累及滑膜衬里的关节、滑囊和腱鞘。根据滑膜受累程度,它有弥漫性和局限性两种形式。PVNS很少累及颞下颌关节(TMJ);一旦累及,临床上表现为缓慢生长且无痛的耳前肿块,类似腮腺肿瘤。可导致颞下颌关节功能障碍、感觉异常和/或听力丧失。我们报告一例颞下颌关节巨大关节外PVNS病例,并对文献进行综述。
