INTRODUCTION
Giant cell tumors (GCTs) of distal ulna are extremely rare accounting for 0.45%-3.2% of all the cases of GCTs. These are locally aggressive and have a higher rate of recurrence of up to 40% with conservative modality of treatment. Proximity to carpus and diminished range of motion makes their treatment a challenge.
CASE REPORT
A 27-year-old male presented to us with swelling right distal ulna. X-ray and MRI were suggestive of GCT. The diagnosis was confirmed by core needle biopsy. The patient was managed by wide resection ulna with extensor carpi ulnaris tenodesis.
CONCLUSION
GCT ulna although very rare in presentation is a possible diagnosis. Wide resection of ulna is a viable treatment option to achieve disease free status. Extensor carpi ulnaris tenodesis helps stabilization of ulnar stump.
引言
尺骨远端骨巨细胞瘤极为罕见，占所有骨巨细胞瘤病例的0.45%-3.2%。这些肿瘤具有局部侵袭性，采用保守治疗方式时复发率较高，可达40%。由于靠近腕关节且活动范围减小，其治疗颇具挑战性。
病例报告
一名27岁男性因右尺骨远端肿胀前来就诊。X线和磁共振成像提示为骨巨细胞瘤。经粗针穿刺活检确诊。患者接受了尺骨广泛切除及尺侧腕伸肌肌腱固定术。
结论
尺骨骨巨细胞瘤尽管临床表现极为罕见，但仍有可能被诊断出来。尺骨广泛切除是实现无病状态的可行治疗选择。尺侧腕伸肌肌腱固定有助于稳定尺骨残端。
