Osteochondroma is the most common type of benign bone tumour. It is a benign chondrogenic lesion derived from aberrant cartilage from the perichondral ring, and it commonly presents in the proximal humerus, proximal femur and knee. Osteochondroma is usually solitary but can be multiple with patients with hereditary multiple exostoses. Malignant changes happen in approximately 1% of cases. Osteochondroma usually causes local pain or swelling. We discuss a unique case of an osteochondroma that highlights the fact that osteochondroma can occur in the most unlikely places, and they should be properly visualised via radiography to evaluate any extensions and compromised surrounding structures before surgical intervention.
骨软骨瘤是最常见的良性骨肿瘤类型。它是一种源于软骨膜环异常软骨的良性软骨性病变，常见于肱骨近端、股骨近端和膝关节。骨软骨瘤通常为单发，但在遗传性多发性骨软骨瘤患者中可多发。约1%的病例会发生恶变。骨软骨瘤通常会引起局部疼痛或肿胀。我们讨论了一例独特的骨软骨瘤病例，该病例突出了骨软骨瘤可发生在最意想不到的部位这一事实，并且在手术干预前，应通过X线摄影对其进行恰当显影，以评估任何扩展情况及周围结构是否受累。
