Lower limb bone hemangiomas in children: report of two cases

Hemangiomas of the bone are rare lesions, accounting for approximately 1% of all primary bone tumors. Hemangiomas occur fairly frequently in the vertebral bodies and the skull, but are unusual in other bones. We report two cases of unusual and fairly rare aspects of this vascular tumor in children. Both cases involved recurrences, which led to a wide bone resection in case 1 and to several curettages in case 2. In these two cases the histological type of hemangioma was capillary. In reviewing the literature we found no indication of wide resection of the benign forms in children.
