Primary Ewing sarcoma of the kidney is a very rare neoplasm that generally occurs in young adults. We report a 69-year-old woman with a history of breast cancer who on a routine annual bone scan was found to have a suspicious area over the right kidney. Computed tomography revealed a 16 by 15-cm mass that was removed by a radical nephrectomy. Pathologic examination confirmed the diagnosis of ...

The BRAFV600E mutation, which in melanoma is targetable with vemurafenib, is also found in sarcomas and we here evaluate the therapeutic potential in sarcoma cell lines. METHODS Four sarcoma cell lines harboring the BRAFV600E mutation, representing liposarcomas (SA-4 and SW872), Ewing sarcoma (A673) and atypical synovial sarcoma (SW982), were treated with vemurafenib and the effects on cell g...

Ewing's sarcoma of the calcaneum is rare. Radiological features of this tumor can be misinterpreted as other benign bone tumors due to its rarity. The overall prognosis of Ewing's sarcoma of calcaneum is inferior compared to other sites of this tumor. Hence, these tumors should have extensive radiological evaluation and histological confirmation as misdiagnosis and treatment delays will have de...

Primary Cranial Ewing sarcoma (ES) is rare and that of temporal bone is even rarer entity. Only a few sporadic cases have been reported and no such case has been reported from Eastern India In this report we describe a case of 18 yrs old male with primary cranial ES of squamous temporal bone involving intracranial and extracranial compartment. The patient presented with swelling in zygomatic fo...

An interview case-control study was undertaken to search for risk factors for Ewing's sarcoma. The 208 cases, aged 5 months to 22 years at diagnosis and all white but one, were identified from hospitals participating in the Intergroup Ewing's Sarcoma Study therapeutic trials. Two controls were sought for each case: a sibling control and an age-matched regional population control identified thro...

Ewing sarcoma is the second most common primary osseous malignancy in children and young adults. However, infrequently, it can arise outside the skeletal system; rarer still, it can originate within the lung parenchyma. In this case report, we describe such a case in a 23-year-old male. We also review the literature to summarize imaging findings for this rare malignancy.

Ewing sarcoma was named after James R. Ewing, an eminent American pathologist at Cornell who described the first cases in 1921. Although he is best remembered for this singular achievement, Ewing's contributions to the study of cancer were far more profound and influential. He essentially launched oncology as a discipline with the publication of his seminal textbook and founded the major Americ...

Congenital Ewing's sarcoma is a very rare occurrence indeed with only one case involving the humerus and none involving the ulna that has been noted in the literature to our knowledge. It is one of those tumours that not only do they rarely occur in the neonatal period, but is also very uncommon in black people. We present a case report of Congenital Ewing's Sarcoma in a black female infant inv...

Although the spine is frequently involved in metastatic Ewing's sarcoma, primary involvement of the spine, beside sacrum, is much less frequent, especially in adult patients. Because of the low incidence of these tumors, there are currently no clinical guidelines outlining their management and a multitude of therapeutic strategies have been employed with varying success. The definitive manageme...

Extraskeletal Ewing sarcoma is covered by other ESMO Guidelines: in general, the same principles for these tumours in children apply to adults. This is also the case for embryonal and alveolar rhabdomyosarcoma, which are exceedingly rare in adults. On the other hand, pleomorphic rhabdomyosarcoma is viewed as a high-grade adult-type soft tissue sarcoma. Gastrointestinal stromal tumours are cover...
