The patient developed delirium; magnetic resonance imaging showed metastatic bone tumors. He died two weeks after admission. Autopsy revealed abdominal aortic intimal sarcoma with metastasis to the peritracheal lymph nodes and sternum. Peripheral arterial embolism and bone metastasis a...

Purpose: Ewing sarcoma is a tumor of the bone and soft tissue characterized by diffuse cell membrane expression of CD99 (MIC2). Single-site, surgically resectable disease is associated with an excellent 5-year event-free survival; conversely, patientswith distantmetastases have a poor prognosis.Noninvasive imaging is the standard approach to identifying sites of metastatic disease. We sought to...

SUMMARY Askin tumor is a peripheral neuroepithelioma originating in chest wall. It is a very aggressive tumor and with Ewing's sarcoma are the most frequent tumors of chest wall. The tumor is composed of small round or ovoid cells arranged in sheets with pseudorossette formation. Some times around vessels, glycogen staining is some times positive in H & E but always positive in E.M. In E.M be...

carney’s complex is a rare autosomal dominantly inherited multiple endocrine neoplasia syndrome that involves spotty skin pigmentations, recurrent cardiac myxomas, endocrine hyperactivity, pituitary adenomas, peripheral nerve tumors, testicular tumors, and ovarian lesions. we present a case of sudden cardiac death in a 40 year old female with a history of carney’s complex with recurrent cardiac...

Monoclonal antibodies Ost6 and Ost7 (mouse Immunoglobulin G1) to human osteogenic sarcoma were isolated from ascitic fluid and labeled with radioiodine. After injection into athymic nu/nu mice with s.c. xenografts of human osteogenic sarcoma, the uptake of radioactivity in tumors, visceral organs, and blood was determined. Five days after injection, Ost6 and Ost7 showed preferential accumulatio...

To date, there have been less than a 100 confirmed case reports of primary cardiac malignant fibrous histiocytomas, a rare form of sarcoma. In this report, we discuss the case of a 15-year-old girl who initially presented with a histiocytic cerebral sarcoma that was treated with aggressive resection and chemotherapy. Three years later, the same patient developed increasing shortness of breath a...

Ewing sarcoma, including classical Ewing sarcoma of the bone and primitive neuroectodermal tumors arising in bone or extraosseous primary sites, is a highly aggressive childhood neoplasm. We present two cases of Ewing sarcoma arising from the vagina in young girls. Previously reported cases in literature focused on their pathologic rather than radiographic features. We describe the spectrum of ...
