Background: The effect of race and ethnicity on some kind of malignant bone tumors including Ewing sarcomahas been proven in different studies. In order to evaluate the latter, national cancer registries may help to increaseunderstanding about potential cancer causes, prevention and control strategies, and apply these findings to controlhealth problems among populations with s...

Introduction: Malignant mesenchymal tumors of the larynx are rare. One type of malignant mesenchymal tumor is synovial sarcoma with unknown histogenesis, which occurs predominantly in the lower extremities of young adults. The head and neck region is a relatively rare location. There are few cases of malignant mesenchymal tumors with laryngeal localization in literature.  Case Report: In this r...

Primary cardiac sarcomas are rare malignant tumors of the heart. Clinical features depend on the site of tumor and vary from symptoms of congestive heart failure to thromboembolism and arrhythmias. Echocardiography is helpful but definitive diagnosis is established by histopathology. Surgical resection is the mainstay of treatment, and the role of chemotherapy and radiotherapy is unclear. We re...

Primary cardiac tumors are rare with an incidence ranging from 0.001% to 0.03% in autopsy series. The prognosis of cardiac sarcomas remains poor because it proliferates rapidly and distant metastases are often found at diagnosis. A 47-year-old male complained of persistent cough. The chest roentgenogram was normal. Subsequent computed tomography revealed a mass in the right atrium. Echocardiogr...

treatment with intensification of chemotherapy using alkylating agents and topoisomerase ii inhibitors and radiotherapy has improved the outcome of patients with solid tumors such as ewing’s sarcoma. however, there are several reports of secondary malignancy following treatment of these tumors. in this article, we describe a 12 years old girl with all who had ewing’s sarcoma when she was 8 year...

Primary malignant heart tumors represent rare entities where fibro sarcoma represents about 3% of all. Introducing the patient: A 15 years old patient with cardiac insufficiency (heart failure) symptoms, such as weakness, cyanosis, palpitations and breathing difficulties; enlargement of upper mediastinum and pleural effusion. Through echocardiography a pericardial effusion and intracavitary thr...

A left atrial mass associated with coronary artery disease is often diagnosed as a mural thrombus rather than other possible etiologies such as benign primary cardiac tumor (myxoma, lipoma), a malignant primary cardiac tumor (sarcoma, lymphoma), or secondary involvement for extracardiac tumors. Malignant lymphoma initially presenting as intracardiac masses is very rare. Chest computed tomograph...

There are very few cases of primary pericardial sarcomas reported in the English literature. Pericardial tumors, like other cardiac tumors, are most likely to be metastatic in nature and are an extension of primary tumors from the surrounding structures. Sarcomas are the most common primary pericardial tumors. Surgical eradication of the tumor is considered to be the treatment of choice. We are...

We present a case report of a patient with a rare primary cardiac tumor, chondrosarcoma. After initial excision, a locally advanced recurrence appeared within six weeks at a different site in the heart with the histological features of a high-grade sarcoma. We discuss the background, management and prognosis of these rare tumors.
