The present report illustrates a very rare case report of a foreign body granuloma of the foot associated with a 2-year period of a retained spongeous rubber foreign body after a penetrating injury. Because it appeared almost 2 years after the injury, the history of trauma was minimized, the foreign body had migrated from the plantar to the dorsal side of the foot, and the radiographic appearance resembled a malignant process, it was difficult to rule out the possibility of a malignant tumor. This case shows the weakness of magnetic resonance imaging in detecting spongeous rubber in the body. Also, a bone osteoblastic reaction to the foreign body has very rarely been noted. To the best of our knowledge, just 5 cases have been previously reported. Provided suspicion exists of previous trauma with an embedded foreign body, the differential diagnosis of a bone neoplasm should consider the possibility of a foreign body reaction. Biopsy proved to be the best diagnostic tool.
本报告展示了一例极为罕见的足部异物肉芽肿病例，该病例与一次穿透伤后海绵状橡胶异物留存两年有关。由于其在受伤近两年后才出现，外伤史被淡化，异物已从足底迁移至足背，且影像学表现类似恶性病变，因此难以排除恶性肿瘤的可能性。该病例显示了磁共振成像在检测体内海绵状橡胶方面的不足。此外，很少有人注意到骨对异物的成骨反应。据我们所知，此前仅报告过5例。如果怀疑既往有外伤且有异物嵌入，骨肿瘤的鉴别诊断应考虑异物反应的可能性。活检被证明是最佳的诊断工具。
