Poorly differentiated round cell sarcomas present diagnostic challenges because of their variable morphology and lack of specific immunophenotypic markers. We present a case of a 15-year-old female with a tibial tumor that exhibited features of Ewing-like sarcoma, including apparent rearrangement of the EWSR1 gene. Hybridization capture-based next-generation DNA sequencing showed evidence of co...
NEW YORK—Hayes Martin, renowned surgeon, died today in Memorial Hospital at the age of 85. He was appointed Chief of the Head and Neck Surgery Section at Memorial Hospital in 1930. In 1942, he became president of the American Radium Society. He is also founder and four-time president of the Society of Head and Neck Surgeons—1954 through 1957.

Ewing sarcoma and primitive peripheral neuroectodermal tumor (PNET) are high-grade malignant tumors typically found in children and adolescents. These tumors belong to the family of small round cell tumors and are of neuroectodermal origin. Primary Ewing sarcoma of the kidney is rare and because of that is an infrequent differential diagnosis in urologic malignancies. Renal PNET mostly presents...
Background: Ewing sarcoma family tumors (ESFTs) are among the most malignant tumors in children and young adults. ESFTs include Ewing sarcoma (ES) and peripheral primitive neuroectodermal tumors (pPNETs). As there seemed to be few studies on the molecular biology of ESFTs, we investigated the frequency of CD99, Ki67, p53 and Fli- 1 protein expression in 15 Iranian patients with ESFTs. In addi...
