A case of multicentric giant cell tumor with synchronous occurrence in all three bones around the knee is reported here in view of its rarity. A 33-year-old average built male reported with complaints of severe pain, gradually increasing swelling around the right knee. A 3 × 2 cm swelling was present on the lateral aspect of the distal end of the right femur and a 3 × 3 cm swelling on the proximal part of the right tibia. Plain X-ray of right knee showed subarticular eccentrically located expansile lytic lesion in the lateral tibia condyle, lateral condyle of femur and patella. Fine needle aspiration cytology and subsequent histology ascertained the diagnosis of giant cell tumor of the bone. The patient was treated successfully with curettage, bone grafting and methyl methacrylate cementing (Sandwich technique).
鉴于其罕见性，本文报告了一例多中心巨细胞瘤同时发生于膝关节周围所有三块骨骼的病例。一名33岁身材中等的男性因右膝严重疼痛、肿胀逐渐加重前来就诊。右股骨远端外侧有一个3×2厘米的肿块，右胫骨近端有一个3×3厘米的肿块。右膝X线平片显示胫骨外侧髁、股骨外侧髁和髌骨的关节下偏心性膨胀性溶骨性病变。细针穿刺细胞学检查及后续组织学检查确诊为骨巨细胞瘤。患者通过刮除、植骨和甲基丙烯酸甲酯骨水泥填充（三明治技术）成功治愈。
