软骨肉瘤是第三大最常见的原发性骨恶性肿瘤。这些肿瘤生长缓慢,很少转移,通常手术后预后良好。在巴西国家创伤和骨科研究所注册和治疗的患者中,在一名63岁的男子中发现了一例罕见的软骨肉瘤,被诊断为阑尾骨骼多中心软骨肉瘤。这个例子在医学文献中是不典型的,因为多中心肿瘤不同于转移事件,它们在软骨肉瘤中的频率很少见。因此,本文提供了罕见的病例报告,并回顾了医学文献中的其他病例。
Chondrosarcomas constitute the 3rd most common primary bone malignancy. These tumours grow slowly and rarely metastasize, usually having a good prognosis after surgery. Among patients registered and treated at the Brazilian National Institute of Traumatology and Orthopedics, an uncommon case of chondrosarcoma was identified in a 63-year-old man, who was diagnosed with multicentric chondrosarcoma of the appendicular skeleton. This example is atypical in the medical literature because multicentric tumours are different from metastatic events, and their frequency in chondrosarcoma is rare. This article therefore provides a rare case report alongside a
review of additional cases in the medical literature.
