Primary cardiac fibroma of the right ventricle in an adult: report of one case.

Cardiac fibroma is a rare primary benign cardiac tumor, especially in adults. It often occurs in the interventricular septum and free wall of the left ventricle and is solitary and space-occupying with clear boundaries. Here we report a 27-year-old male with a cardiac fibroma in the right ventricle, with extensive infiltrative growth. He was admitted to hospital with the complaint of exertional chest tightness, shortness of breath, hemoptysis, and edema of lower extremities. Ultrasound showed a large right ventricular mass blocking the outflow tract. The patient underwent palliative resection. Pathologic examination and Masson staining showed that collagen tissue proliferated and infiltrated myocardial fibers. The final diagnosis was cardiac fibroma. IJCEP
