背景:骨巨细胞瘤(GCT)是一种常见的良性原发性骨肿瘤,常见于股骨远端,胫骨近端和桡骨远端。据报道,肱骨远端很少有GCT病例。我们报告了一名25岁男性在左肱骨内侧髁和上髁复发性巨细胞瘤的不寻常表现。
方法:患者3年前出现左肘溶解性病变。因为它是一个不常见的肿瘤部位,误诊为结核性骨髓炎,刮除不充分。患者在初次手术后一年出现肿瘤复发。我们对肿瘤进行了整块切除,明智地移除部分滑车。尽管计划重建,由于每次手术肘部稳定,因此发现没有必要。患者恢复了接近正常的肘部运动,没有不稳定。他的MayoElbow性能得分从30提高到85。随访2年无复发或转移。
结论:虽然在肱骨远端很少见骨肿瘤,需要进行活检以确认该区域任何溶解性病变的诊断,以便进行适当的治疗。
BACKGROUND: Giant cell tumour of bone (GCT) is a common benign primary bone tumour, seen commonly in the distal Femur, proximal Tibia and distal Radius. Very few cases of GCT are reported in distal humerus. We report an unusual presentation of recurrent Giant cell tumour in a 25 year old male in the medial condyle and epicondyle of left Humerus.
METHODS: Patient presented elsewhere with lytic lesion of left elbow three years ago. As it is an uncommon site for tumors, it was misdiagnosed as tuberculous osteomyelitis and was inadequately curetted. Patient presented to us with recurrence of tumor one year after the primary surgery. We did en-bloc resection of the tumour, with judicious removal of partial trochlea. Though reconstruction was planned, it was found to be not necessary as the elbow was stable per-operatively. Patient regained near normal movements of the elbow with no instability. His Mayo Elbow Performance score improved from 30 to 85. There is no recurrence or metastasis of the tumor in the two-year follow-up.
CONCLUSIONS: Though bone tumors are rare in distal Humerus, biopsy is needed to confirm the diagnosis of any lytic lesion in this region for proper management.
