Pigmented villonodular synovitis (PVNS) occurs most frequently in the knee and hand joints and is extremely rare in the shoulder joints. A 27-year-old women was admitted to our outpatient clinic with an abrupt-onset pain and limited range of motion of the left shoulder. On arthroscopic examination, localized PVNS surrounding the reactive synovitis in the posterior aspect of the subscapularis within the shoulder joint cavity. The mass was removed using a grasper and shaver. Symptomatic relief was achieved following surgical removal. In conclusion, although rare, localized PVNS of the shoulder joint should be kept in mind in patients with a sudden-onset shoulder joint subluxation and pseudoparalysis.
色素沉着绒毛结节性滑膜炎（PVNS）最常发生于膝关节和手部关节，而在肩部关节极为罕见。一名 27 岁女性因左肩突发疼痛和活动受限就诊于我院门诊。关节镜检查发现，肩关节腔内肩胛下肌后关节囊处存在反应性滑膜炎，周围有局限性 PVNS。使用抓钳和电动刨削器切除了肿块。手术后症状得到缓解。总之，虽然罕见，但对于突发肩关节半脱位和假性瘫痪的患者，应考虑肩部局限性 PVNS 的可能性。
