Its pathogenesis and natural history are not fully understood, and its management remains controversial.CASE SUMMARY A 56-year-old male complaining of heel pain was diagnosed with an os calcis lipoma. The lesion was treated with curettage and it was filled with impacted allograft and demineralized bone matrix. Histological examination confirmed the above diagnosis. Six months postoperatively, the patient returned to recreational long-distance running. Repeated computed tomography scanning, up to five years postoperatively, showed almost complete resorption of the graft over time.CONCLUSION The treatment of an os calcis lipoma should be individualized, depending on the symptoms, the location and size of the lesion. Surgeons, electing to proceed with bone grafting, should consider the probability of bone graft resorption.展开更多
