We report an occurrence of periosteal chondroma seeding into the medulla of humerus via percutaneous needle biopsy tract. To our knowledge, this is the first described case of benign cartilage tumour biopsy tract seeding in the literature. We discuss the clinical, radiological and histological features of periosteal chondroma, as well as the diagnostic challenges associated with distinguishing this entity from periosteal chondrosarcoma. Finally, we briefly discuss the safety of imaging-guided percutaneous needle biopsy and methods to minimize the risk of iatrogenic tumour seeding.
我们报告了一例骨膜软骨瘤经皮穿刺针活检通道播散至肱骨髓腔的病例。据我们所知，这是文献中首次描述的良性软骨肿瘤活检通道播散的病例。我们讨论了骨膜软骨瘤的临床、放射学和组织学特征，以及将该实体与骨膜软骨肉瘤区分开来所面临的诊断挑战。最后，我们简要讨论了影像引导下经皮穿刺针活检的安全性以及将医源性肿瘤播散风险降至最低的方法。
