Multifocal Ewing's sarcoma and hypercalcemia. A case report

An unusual case of Ewing's sarcoma in which the earliest sign of disease was the development of hypercalcemia is described. Radiologic examinations showed extensive osteolysis involving all of the trunk, and the proximal femora and humeri. An ill defined destruction of the left fibula was also noted. No definite primary site was found. The lungs and other visceral organs were free of metastasis. To the best of the author's knowledge, no comparable case has been reported in the literature.
