PRIMARY SARCOMA OF THE PERICARDIUM

Primary high-grade myofibroblastic sarcoma arising from the pericardium.

Primary pericardial sarcomas are very rare. A 62-year-old Japanese man presented with cardiac tamponade. Echocardiography, computed tomography and magnetic resonance imaging revealed massive pericardial effusion and a large tumor in the pericardial cavity, attached to the pericardium of the left ventricular posterolateral free wall. Surgical excision of the tumor was performed and histopatholog...

Primary Mesothelioma of the Pericardium

A PATIENT with a pericardial effusion may frequently present a diagnostic problem. A primary malignancy of the heart or pericardium is one of the rare causes of such an effusion. Lymburner1 at the Mayo Clinic reported an incidence of .05 per cent in 8,500 consecutive autopsies. Mesotheliomas compose only a small percentage of the primary tumors of the heart and pericardium. Dawe, Wood, and Mitc...

Primary malignant sarcomatoid mesothelioma in the pericardium.

Primary malignant pericardial mesothelioma is an exceptionally rare tumor, and making an antemortem diagnosis of this disease is notoriously difficult. We herein report the case of a 61-year-old woman with pericardial mesothelioma who presented with shortness of breath and peripheral edema of the lower limbs. Chest computed tomography (CT) showed an anterior mass and thickened pericardium with ...

Primary Stromal Sarcoma of Breast with Nodal Recurrence

  Although most breast cancers are adenocarcinomas of the mammary gland, primary breast sarcomas may also arise from mammary gland mesenchymal tissue. Sarcomas represent less than 1% of primary breast neoplasms. These tumors are at high risk of recurrence and are known to have poor prognosis. Surgical resection is the primary treatment for these lesions and axillary lymph node dissection is no...
