We present an atypical case of histopathology suggesting hemangioendothelioma and immunohistochemistry-proven Ewing's sarcoma in a 39-year-old lady who presented with multiple stony hard swellings involving the occipital region of the scalp, right cervical lymph node, right scapular region, left infraclavicular region of the chest, right anterior abdominal wall swelling, and inner aspect of right thigh. She underwent left-sided below-knee amputation for parosteal osteosarcoma in the left distal tibia 3 years back. Palliative radiotherapy with dose of 30 Gy in 10 fractions over 2 weeks was administered to the right neck and right upper back following which she attained moderate pain relief but no reduction in swellings as was expected had it been a case of hemangioendothelioma or Ewing's sarcoma..
