RESUMO
The authors present two case studies of giant cell tumor of tendon sheath. This uncommon lesion of the lower extremity is presented in these two cases in correlation with clinical, radiographic, and intraoperative findings. After the pathologic diagnosis was made, the patient in the first case decided not to have the tumor resected. This patient's postoperative course continues uneventfully without expansion of the tumor. In the second case, a local recurrence was noted 13 months after en bloc resection. A review of the literature shows that treatment modalities for such lesions range from marginal excision to radiation therapy. The authors wish to emphasize the high risk of local recurrence of these tumors. Early marginal resection is the treatment of choice.

A 7-year-old black male presented with a lytic, expansile lesion of the calcaneus. This lesion was studied with conventional x-rays as well as MRI. The MR examination demonstrated a multiloculated lesion with material of a high- and low-signal intensity appreciated within each loculation. Pathologic review of the lesion demonstrated an aneurysmal bone cyst.
