Abstract

A patient with a benign bizarre parosteal osteochondromatous proliferation (BPOP) located in the anterior knee was treated with resection in preparation for total knee arthroplasty (TKA). The BPOP reoccurred and was treated with re-resection at the time of TKA. The BPOP reoccurred a second time and underwent malignant transformation to a fungating high-grade pleomorphic sarcoma with metastatic lesions. This case highlights the rare potential of a previously benign BPOP to undergo malignant transformation after recurrence. A wide margin resection may be considered primarily when surgery is indicated to prevent recurrence and its potential sequelae. [Orthopedics. 2024;47(6):e322-e326.].

伴有恶性转化和转移的奇异骨旁骨软骨瘤增生

一名膝关节前部良性骨旁骨软骨瘤增生（BPOP）患者在准备进行全膝关节置换术（TKA）时接受了切除治疗。在进行全膝关节置换术（TKA）时，BPOP再次发生并再次切除。BPOP 第二次复发，并恶变为伴有转移灶的真菌性高级别多形性肉瘤。本病例强调了先前为良性的 BPOP 复发后发生恶变的罕见可能性。当需要进行手术以防止复发及其潜在后遗症时，可主要考虑广缘切除。[骨科。202x;4x(x):xx-xx]。
