Ewing sarcoma is a type of pediatric cancer [5] that forms in bone or soft tissue. [1] Symptoms may include swelling and pain at the site of the tumor, fever , and a bone fracture . [ 2 ] The most common areas where it begins are the legs, pelvis , and chest wall. [ 4 ]
The Ewing family of tumors (EFTs) is a group of small cell sarcomas including Ewing sarcoma of the bone, extra osseous Ewing tumors, and primitive neuroectodermal tumors. They are rare cancers, usually diagnosed in peoples' twenties. The sarcoma of bone is the most common of the variants. All forms are predisposed to metastasis and have had ...
H&E stain. Desmoplastic small-round-cell tumor (DSRCT) is an aggressive and rare cancer that primarily occurs as masses in the abdomen. [4] Other areas affected may include the lymph nodes, the lining of the abdomen, diaphragm, spleen, liver, chest wall, skull, spinal cord, large intestine, small intestine, bladder, brain, lungs, testicles ...
Small blue round cells of Ewing Sarcoma Display of small round blue cells characteristic of desmoplastic small round cell tumour.. In histopathology, a small-blue-round-cell tumour (abbreviated SBRCT), also known as a small-round-blue-cell tumor (SRBCT) or a small-round-cell tumour (SRCT), is any one of a group of malignant neoplasms that have a characteristic appearance under the microscope ...
Usual onset. Rapid, <5years and >35years of age [2] Diagnostic method. Medical imaging [2] Treatment. Chemotherapy, surgical removal, radiation therapy [2] Frequency. 0.4 per million, males=females [2] Extraskeletal Ewing sarcoma (EES), is a cancer of soft tissue, a type of Ewing sarcoma that does not arise from bone.
Chondrosarcoma is a bone sarcoma, a primary cancer composed of cells derived from transformed cells that produce cartilage. [1] A chondrosarcoma is a member of a category of tumors of bone and soft tissue known as sarcomas. About 30% of bone sarcomas are chondrosarcomas. [2] It is resistant to chemotherapy and radiotherapy.
Primitive neuroectodermal tumor. Micrograph of an H&E stained section of a peripheral PNET. Primitive neuroectodermal tumor is a malignant (cancerous) neural crest tumor. [1] It is a rare tumor, usually occurring in children and young adults under 25 years of age. The overall 5 year survival rate is about 53%.
Ewing's Sarcoma is a bone cancer affecting mainly children and adolescents. [19] Tumors of Ewing' Sarcoma are typically found in the long bones of the legs and arms, or bones in the chest, trunk, pelvis, back, or head. [20] Beckerle's research in this area focuses on a key pathway as believed to be a mechanism by which the cancer cells can spread.
