A 60-year-old man presented with left hip pain, and a radiograph showed reduced joint space. During the surgical procedure for a total hip replacement, a proximal femur mass was identified and biopsy was subsequently interpreted as grade 2 chondrosarcoma. A wide resection was needed, but he developed local recurrence after 2 years and was treated with an external hemipelvectomy.
Chondrosarcoma does not always present with a classical clinical picture or imaging, and it can be misdiagnosed. Practitioners should be highly suspicious of malignant disease as a cause for hip pain even if there is no direct indication of a neoplasm such as chondrosarcoma.
一名60岁男性因左髋疼痛就诊，X线片显示关节间隙变窄。在全髋关节置换手术过程中，发现股骨近端有肿物，随后活检结果为2级软骨肉瘤。需要进行广泛切除，但2年后他出现了局部复发，接受了半骨盆切除术。
软骨肉瘤并不总是表现出典型的临床表现或影像学特征，可能会被误诊。即使没有诸如软骨肉瘤等肿瘤的直接迹象，医生也应高度怀疑恶性疾病是髋部疼痛的原因。
