title: Possible infectious etiology of six cases of Ewing's sarcoma in Western Australia.
abstract: Six cases of Ewing's sarcoma occurring in Western Australia during a 2-year period are reported. All six patients lived in rural habitats and reported exposure to farm animals. There was evidence of direct contact between two patients over a 3-year period preceding the diagnosis of their tumors. These features raise the possibility that Ewing's sarcoma has an infectious etiology.
