Ewing Sarcoma

Ewing sarcoma

Ewing's (or Ewing's sarcoma) sarcoma was described by James E. Ewing in 1891 and named after him.

He was born in South Whitbourne, New York, New York. He was the eldest son of James A. and Abigail (Lindsay) Ewing. Grew up in Bridgeport, Connecticut. In 1901, he graduated from the Brigham Young School, one of the oldest Kansas-type schools in the United States. He then studied medicine at Yale University in Bronx-Hartford, a place that became home to many famous doctors. After college, he returned to Brighampton to become a doctor. But later he moved back to New York and became involved in science.

In 1886, Ewing described mucosal sarcomas that were sometimes associated with meningioma. Several years later, he discovered tumor tissue in the small intestine in the boy's abdomen. It became difficult for pathologists to distinguish them, and he described them as a unique group of tumors, which he called Ewing's gland sarcoma. These tumors had a characteristic cluster appearance, originated in the intestines and often metastasized throughout the body. Over time, tumor cells become visible in the bone tissue, on the joint lining, or above the knee. He later discovered that they could form on any part of the body, including the jaw, eye and ovaries. The development of these sarcomatous primordia was explained by the fact that the cells of the gland tissue had an immunological feature that promoted the growth of tumor cells.

He later gave them the common name “Ewing gland sarcomas.” The name Ewing's sarcoma is still used today, although some doctors prefer to call it something more specific, such as "stomach deposit." As of December 17, 2022, **Ewing sarcoma**, also known as Ewing, is one of the soft tissue tumors with the highest mortality rate. It was first described by James Ellison and Alvin Ewings in France.

What stages are the metastases of Yuuinsky sarcoma divided into? | **Start** | **Development** | | :---: | :-------| | Modification of the structure and size of the tumor without noticeable bleeding. | Significant increase in tumor volume, its hardening, spread to neighboring organs

Tumors are not classified according to the size of the underlying tumor. Benign tumors indicate that the tumor grows slowly, not
