Answer

Physical examination findings are usually limited to the site of the primary tumor, as follows:

  • Mass - A palpable mass may or may not be present; the mass may be tender and warm, though these signs are indistinguishable from osteomyelitis; increased skin vascularity over the mass may be discernible; pulsations or a bruit may be detectable
  • Decreased range of motion - Involvement of a joint should be obvious on physical examination
  • Lymphadenopathy - Involvement of local or regional lymph nodes is unusual
  • Respiratory findings - Auscultation is usually uninformative unless the disease is extensive
