Ewing sarcoma/peripheral primitive neuroectodermal tumor (ES/pPNET) is a malignant small, round cell tumor arising from bone and soft tissue in children and young adults. It can occur at osseous and extraosseous sites. Its usual locations are diaphysis of long bones followed by pelvis, ribs, vertebrae, and rarely skull. We reviewed the literature and PubMed advanced search on ES/pPNET occurring...

We present a pediatric case of primary endobronchial Ewing sarcoma family of tumors. CASE REPORT A 12-year-old boy presented with dyspnea and chest radiography showed right pulmonary atelectasis.

BACKGROUND Liposarcoma is the most frequent soft tissue sarcoma. Well differentiated liposarcoma may progress into dedifferentiated liposarcoma with pleomorphic histology. A minority additionally features myogenic, osteo- or chondrosarcomatous heterologous differentiation. Genomic amplification of the Mouse double minute 2 homolog (MDM2) locus is characteristic for well differentiated and dedif...

There are a number of recognized causes of digoxinresistant atrial fibrillation, one of which is infiltration of the heart by malignant tumour. Extraosseous deposits of myeloma can be found in about 70 per cent of cases by careful necropsy (Hayes, Bennett, and Heck, I952; Churg and Gordon, 1950), the liver, spleen, and lymph nodes being by far the commonest sites. Cardiac involvement at necrops...

Hydatid cysts caused by Echinococcus species mainly involve visceral organs. Rarely skeletal involvement occurs. The spine and pelvis account for half of the cases osseous hydatidosis, making humeral hydatid one rarest conditions. We report a case hydatidosis in 42-year male who presented to us with pain swelling over left upper arm, radiological investigations suggestive cystic lesions were in...
