Cancer, 1986
Ewing's sarcoma is a small cell malignant tumor that usually arises in the medullary cavity of bone. Less frequently, it originates in soft tissue and may secondarily invade underlying bone. The origin of Ewing's sarcoma in a periosteal location without extension into either the bone or adjacent soft tissue has not been clearly documented.

Retroperitoneal Ewing’s Sarcoma
Urologia Internationalis, 1995We report a case of extraskeletal Ewing's sarcoma arising in the retroperitoneal cavity. The tumor was excised en bloc with the left kidney and infiltrated portion of the left ureter. Histological diagnosis was confirmed by both electron micrography and immunohistochemical staining using a newly developed mouse monoclonal antibody 5C11, which ...

AbstractA case of Ewings sarcoma arising in the soft tissue of the thumb is described. This appears to be the first case of digital extraskeletal Ewings sarcoma. The soft tissue location, the primary rather than metastatic nature, and the tumor type in this case were well documented.

Future Oncology, 2010
Although Ewing sarcoma represents a rare malignancy of childhood and adolescence, it has attracted the attention of an increasing number of excellent researchers. With a tumor-specific EWS-ETS translocation coding for a transcription factor, which obviously profoundly modifies the intracellular signaling network, this rare malignancy opens insights in ...

Pediatric Blood & Cancer, 2005
The occurrence of primary extraosseous Ewing sarcoma (EES) of the central nervous system (CNS) has only rarely been reported in the literature. It is important to distinguish this entity from the more common central primitive neuroectodermal tumor (PNET) of brain, since the management of these tumors is different from that of EES.

Journal of Neuro-Ophthalmology, 1998
Three patients with intracranial Ewing's sarcoma had neuro-ophthalmologic manifestations. In one patient, the primary tumor was in the skull and in two, it involved the long bones. Two patients complained of intermittent headache associated with bilateral, transient visual symptoms suggestive of migraine, which prompted imaging that showed occipital ...

JBJS Journal of Orthopaedics for Physician Assistants, 2020
The 2 most common types of primary bone tumors in children and adolescents are osteosarcoma and Ewing sarcoma (ES). Common sites of presentation for ES include the long bones, pelvis, chest wall, and spine. Definitive diagnosis of ES is made via open or core needle biopsy. The standard treatment regimen of ES includes neoadjuvant chemotherapy, followed

Ewing sarcoma and Ewing-like tumors
Virchows Archiv, 2019Ewing sarcoma (ES) and Ewing-like sarcomas are highly aggressive round cell mesenchymal neoplasms, most often occurring in children and young adults. The identification of novel molecular alterations has greatly contributed to a profound reappraisal of classification, to the extent that the category of undifferentiated round cell sarcoma has ...

Ultrastructural Pathology, 1987
A well documented case of extraskeletal Ewing's sarcoma arising in a finger of a 16-year-old man was studied by light microscopy, immunohistochemistry and electron microscopy. The differential diagnoses of similar "round cell neoplasms" are discussed.

Optimal management of Ewing’s sarcoma requires the comprehensive efforts of a multidisciplinary team of clinicians who understand the potential benefits and consequences of each treatment modality. Every effort should be made to enroll patients in prospective clinical trials to ensure appropriate quality assurance and standards of care.
