Stainless steel intra-medullary nail linked to adjacent angiosarcoma initially misdiagnosed as an infection.
Angiosarcoma of bone can rarely develop adjacent to orthopedic metal implants and may be misdiagnosed as infection.
Raises caution for malignancy in chronic implant-site "infections"; hypothesis-generating for rare metal implant-associated angiosarcoma.
Malignant vascular tumors (angiosarcoma) of bone are rare and represent a less than 1% of malignant bone tumors. The authors report a case of a patient with angiosarcoma misdiagnosed as infection;which developed adjacent to a stainless steel intra-medullary nail used for fixation of a femur fracture.

Park et al. (2012) studied this question. A stainless steel intra-medullary nail used for femur fracture fixation was associated with the development of an adjacent angiosarcoma initially misdiagnosed as an infection.
