Abstract
Two cases of papillary endocardial excrescence of the right atrium are reported. These lesions are similar histologically to the papillary endocardial “tumors” of the heart valves. The differentiation from cardiac myxomas is discussed and it is concluded that these two cases represent a distinct lesion of the right atrium. The histologic pattern of the lesion suggests origin in an organizing thrombus.Keywords
