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 ...
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%.

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 ...
