The mass occupied the entire RV outflow tract (Figure 2).
Surgical specimen consisting of a 12-gram pink-tan rubbery mass that is 4.7 x 2.6 x 2.1 cm. A scant amount of red-tan, shaggy adherent tissue is present on one edge representing the papillary muscle penetrated by the tumor. The sacrificed chordae tendinae traversing the lesion can also be seen on the other edge.
