Tenosynovial giant cell tumors are extremely rare tumors with highly nonspecific symptoms. This benign but aggressive disease has a slow course of progression; however, it can ultimately lead to irreversible damage to a joint. Here we describe a case of a 45-year-old female with a diagnosis of tenosynovial giant cell tumors of the distal tibiofibular joint, the second case described in the literature for such location. Appropriate imaging studies and ultimately histologic studies are necessary for the correct diagnosis. Some locations are particularly unusual for these tumors making a high level of suspicion as well as treatment by an oncology orthopedic surgery specialist at a high-volume center paramount.
腱鞘巨细胞瘤是极其罕见的肿瘤，症状高度非特异性。这种良性但具有侵袭性的疾病进展缓慢；然而，它最终可能导致关节不可逆转的损伤。在此，我们描述一例45岁女性，诊断为胫腓远端关节腱鞘巨细胞瘤，这是文献中报道的该部位第二例病例。正确诊断需要进行适当的影像学检查以及最终的组织学检查。这些肿瘤在某些部位特别罕见，因此高度怀疑以及由大容量中心的肿瘤整形外科专家进行治疗至关重要。
