Ewing Family of Tumors (PDQ®): Treatment
This cancer treatment information summary provides an overview of the prognosis, diagnosis, classification, staging, and treatment of the Ewing family of tumors (EFT). In this review, the EFT includes bone primaries (classic Ewing sarcoma, primitive neuroectodermal tumor, and Askin tumor [chest wall]), which will be...

Ewing's sarcoma is a sarcoma of the bone classically described under small round blue cell tumors (SRBCT). There is considerable clinical and histologic overlap between this tumor and the primitive neuroectodermal tumor (PNET). For many years, pathologists struggled to make a diagnostic distinction. Now with sophisticated molecular biological analysis, it...

Discussion: - prevalence: - it represents approx 7% of all primary bone malignancies; - Ewing's sarcoma is more common in males and is rare in blacks;...

Ewing's sarcoma is a malignant tumor that belongs to a broader family of tumors that includes PNET (primitive neuroectodermal tumors). In simple terms, these tumors are all pathologically characterized by the so-called "small round blue cells." Ewing's sarcoma almost always occurs in bone, although other members of the PNET family...

16 year old girl had a 6 month history of pain in the left leg, particularly when playing tennis. There is slight irregularity and thickening of the pectineal line and a subtle soft tissue mass on the left side of the pelvis with its centre of radius roughly over the left...

There is a fracture of the diaphysis of the femur through a central lytic area. The process involves patchy bone destruction with irregular undermining of the bone cortex. The endosteal margin of the lesion is ill-defined with a wide margin of transition between normal and abnormal bone. There are islands...

Boy aged 7 years with pain and swelling in his right leg. There is a patchy lytic lesion with some expansion of the lower section of the diaphysis of the left tibia. The endosteal margins of the lesion are ill-defined, having a wide zone of transition between normal and abnormal bone....

Primitive Neuroectodermal Tumor (PNET) is a soft tissue sarcoma classically described under small round blue cell tumors (SRBCT). There is considerable clinical and histologic overlap between this tumor and Ewing's sarcoma (ES). For many years, pathologists struggled to make a diagnostic distinction. Now with sophisticated molecular biological analysis, it turns...

This tumour occurs at a younger age than osteosarcoma and its range of incidence is primarily between 5 - 30 yrs. The patient usually presents with pyrexia pain and may have an elevated ESR. The tumour involves a long bone, particularly the diaphysis. 40% of cases of Ewings sarcoma are...

This is a descriptive category describing a large number of malignant tumors that tend to occur in childhood. They are united by having a similar histologic appearance, that is, small round blue cells. Subtle clues may be present to distinguish between the tumors. The pathologist is assisted by immunohistochemistry, electron...
