primary bone tumors are the sixth most common neoplasm occurring in children and constitute approximately 6% of all childhood malignancies with a peak incidence in 15- to 19-year- old individuals. these lesions are the third most common tumors in adolescents and young adults (exceeded only by leukemia and lymphoma) common complaints are intermittent to constant mild to severe pain, constitution...

conclusions the authors emphasize on the rarity of this pathology among children, its clinical polymorphism, the necessity of a rapid diagnosis, and an appropriate treatment to avoid complications and recurrence of the tumor. introduction right atrial myxoma is a rare disease among children and its clinical presentation is not specific. case presentation we reported a four-year-old girl with ex...

BACKGROUND Primary tumors of the heart are rare even in major cardiac surgery centers. Because of the low case numbers, there is an insufficient evidence base to determine the optimal treatment, particularly for malignant tumors. METHOD The authors review the pertinent literature retrieved by a selective PubMed search on the terms "cardiac tumor," "heart tumor," "cardiac myxoma," and "cardiac...

Cardiac sarcomas are rare malignant tumors. Angiosarcoma is the most common cardiac sarcoma and is present in up to 33% of cases. Angiosarcomas have a poor prognosis, with a short survival expectancy. We report a case of a right atrial angiosarcoma treated by partial tumor resection followed by chemotherapy.

Cardiac tumors, either benign or malignant, are difficult to diagnose due to their rarity, variety, and nonspecific presentation. Since primary cardiac sarcoma remains an unusual diagnosis, the literature on its presentation, diagnosis, and optimal management remains scarce. To our knowledge the following case of cardiac perivascular epithelioid cell tumor is the fourth reported case found in t...

Abstract A 47 years old man, with no previous medical history, presented to the emergency department for dyspnea increased over prior weeks. The echocardiographic evaluation revealed a severe pericardial effusion. Moreover, round-shaped, indeterminate mass was detected into pericardium, partially enhanced after injection SonoVue R contrast. After pericardiocentesis, exclude dilatation of corona...

Ewing Sarcoma is the second most common primary bone cancer. To date, only a few cases of cutaneous have been published. We present unique case Sarcoma, which presented as blue to violaceous mass on young woman’s chest. The lesion clinically did not align with previous reports but pathology and immunohistochemical stains confirmed diagnosis. Because may masquerade benign tumors, dermatologists ...

Primary cardiac tumors are rare. Myxoma and sarcoma are the most common types of benign and malignant cardiac tumors, respectively. Secondary cardiac tumors, the majority of which are metastases, are more common than primary tumors. The use of an appropriate combination of cardiovascular imaging techniques is necessary for the differential diagnosis of cardiac tumors and for preoperative examin...

sarcomas are rare tumors account for about 1% of cancers in adult. soft tissue sarcomas are the most common one. synovial sarcoma's incident is about 10% of all sarcomas and most commonly rise from para-articular regions in young adults. based on our knowledge there have been only two reports of thyroid synovial sarcoma in medical literature. we report a 44-year old woman presented with a rapid...

Primary cardiac tumors are rare. Nearly 25% of primary cardiac tumors are malignant, with rhabdomyosarcoma being the second most common primary sarcoma. Symptoms are variable, and the clinical presentation depends on the location and propagation of the tumor. Transthoracic and transesophageal echocardiography are preliminary tests in diagnosing the disease. Echocardiographic findings should be ...
