Ikeda, T., Ishihara, T., Yoshimatsu, H., Kikuchi, K., Murakami, M., Kobayashi, K., Inoue, H., and Kasahara, M. (1974). Thorax, 582-588. Primary osteogenic sarcoma of the mediastinum. A 22-year-old man with primary osteogenic sarcoma of the superior mediastinum is reported. This case is the second instance of primary osteogenic sarcoma of the mediastinum and the first case of superior mediastina...

Non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) are less responsive to radiotherapy than the more common pediatric soft tissue sarcomas, rhabdomyosarcoma and Ewing sarcoma of soft tissue. However, radiation therapy does play an important role in the treatment of NRSTS, including synovial sarcoma. Little data exists regarding the behavior or treatment of these tumors in adolescents and young a...

Background: Although ionizing radiation is a risk factor, it is a therapeutic agent for cancer. Objectives: The protective and defensive effect of L-Carnitine and vitamin E on gastrointestinal tract organs (liver, spleen and intestine) post whole body gamma irradiation exposure. Material and methods: 56 male albino rats, which were divided into four groups (14 rats per group); group (I): Contro...

Background: Ewing’s sarcoma is one of the common malignant childhood tumours. The radiological features pre-sacral may mimic primary nerve sheath tumor or teratoma. Case Presentation: A 16-year-old girl presented with acute retention urine found to have a midline mass in region pelvis clinical examination and scans. preoperative biopsy was not done. complex location need excise tract, if histol...

Malignant tumours of myofibroblasts are rare lesions. Post radiation sarcoma is a rare potential late sequel of ionizing radiation. We present the first case of myofibrosarcoma of the hypopharynx in a 67-year-old man, occurring 16 years after radiotherapy for laryngeal carcinoma.

Ewing's sarcoma (ES) cells express high levels of poly(ADP-ribose) polymerase (PADPRP) and are responsive to killing by ionizing radiation. We have determined that ionizing radiation induced a pronounced but reversible G2-M phase cell cycle arrest that was maximum by 24 h after exposure. Following the release from this block, floating cells began to appear. These floating cells were shown to be...

Soft tissue sarcomas are uncommon tumors, and intraduodenal soft tissue sarcoma manifestation is even more rare. Only three cases of intraduodenal sarcomas have been reported in the literature thus far. Here, we report a case of an intraduodenal recurrence of a retroperitoneal sarcoma causing bowel obstruction. This unusual recurrence pattern likely relates to the patient's previous resection a...
