Three cases of benign soft tissue osteochondroma, a lesion of uncertain pathogenesis, are reported. Two cases were located in the subcutaneous tissues beneath the calcaneus. The other was located in the soft tissues near the left ankle joint. The diagnosis of soft tissue osteochondroma should be considered when a well-defined osseous mass is located in the soft tissues. The differential diagnosis includes myositis ossificans, tumoral calcinosis, synovial chondromatosis, and soft tissue osteosarcoma.
报告了3例良性软组织骨软骨瘤，这是一种发病机制不明的病变。2例位于跟骨下方的皮下组织。另一例位于左踝关节附近的软组织。当软组织中出现边界清晰的骨性肿块时，应考虑软组织骨软骨瘤的诊断。鉴别诊断包括骨化性肌炎、肿瘤性钙化、滑膜软骨瘤病和软组织骨肉瘤。
