Purpose. To describe successful palliation of a patient with metastatic adamantinoma presenting with lung metastases and hypercalcemia resulting from a parathormone-like substance released from the tumor. Methods and materials. The records of a patient with a history of a tibial adamantinoma who presented with symptoms of hypercalcemia 20 years after the original surgery, as well as the literature concerning hypercalcemia and adamantinoma were reviewed and summarized. Results. After thorough review of the literature we found no prior reports of radiation being used for palliation of hypercalcemia associated with metastatic adamantinoma. We report rapid improvement in symptoms and normalization of serum calcium levels following a course of radiation therapy. The patient remains asymptomatic 15 months following radiotherapy despite a gradual return of elevated serum calcium levels. Discussion. Radiation therapy should be considered as a palliative option for patients who are not surgical candidates presenting with medically refractory hypercalcemia.
