Ewings Sarcoma of 4th Metacarpal Bone of Right Hand, A Rare Case Report

Ewings sarcoma of the hand is relatively rare. Ewings sarcoma can present with minimal pain and swelling of the affected digit. The Erythrocyte sedimentation rate and C-reactive protein may be high. Because of these features, this can be confused with an inflammatory lesion. This leads to starting of inappropriate treatment and delay in diagnosis. Radiologically, Ewings sarcoma can present with a plethora of features from permeative bone destruction to expansile lesions with or without periosteal reaction. We present a case of 10 year old male, with complaints of pain and swelling in right hand, which on X-ray showed periosteal reaction, giving a sun burst appearance. So the provisional diagnosis of osteosarcoma was made. The diagnosis of ewings sarcoma was made on FNAC [fine needle aspiration cytology] which was later on confirmed on histopathology. We intend to report this case, because it is very rare location and the radiological features can mimic other lesions which commonly occur in this location like chronic osteomyelitis, osteosarcoma so it can be easily missed especially at preliminary evaluations.
