They belong to Ewings family of tumours and the primitive neuroectodermal tumour is often diagnosed based on immuno histochemistry and molecular genetic studies. Discussion: A 50-year-old gentleman presented with complaints of a swelling in the right thigh. With a diagnosis of soft tissue sarcoma, the patient underwent a wide local excision of the tumour. We review literature of the small round blue cell tumour. Conclusion: Extraosseous Ewings sarcoma presenting as a thigh swelling is uncommon. The sarcoma was vimentin positive and CD99 membrane positivity.展开更多
文摘Introduction: Ewings sarcoma is uncommon in extra osseous locations. They belong to Ewings family of tumours and the primitive neuroectodermal tumour is often diagnosed based on immuno histochemistry and molecular genetic studies. Discussion: A 50-year-old gentleman presented with complaints of a swelling in the right thigh. With a diagnosis of soft tissue sarcoma, the patient underwent a wide local excision of the tumour. We review literature of the small round blue cell tumour. Conclusion: Extraosseous Ewings sarcoma presenting as a thigh swelling is uncommon. The sarcoma was vimentin positive and CD99 membrane positivity.
