title: [Solitary fibrous tumor of the pericardium].
abstract: A 60-year-old man with a large pericardial effusion was found to have a large intrapericardial mass located anteriorly to the right ventricle and firmly attached to the ascending aorta and pulmonary trunk. Histologically the mass, which was completely excised together with its large base of implant, was found to be a Solitary Fibrous Tumor. After a 46-months follow-up the patient is free from symptoms and signs of recurrence. Solitary Fibrous Tumor is considered a benign tumor and its excision curative, however aggressive variants and metastasis have been reported. Patternless architecture, fibrous collagenous stroma, exclusive vimentin positivity and the lack of ultrastructural mesothelial markers are important tools for the diagnosis. Because of the extreme rarity of intrapericardial location and lack of information on long-term behaviour of this tumor, close non-invasive follow-up is necessary.
