Atrial Myxoma

Atrial Myxoma •This is a bisected myxoma measuring 4-5 cm in greatest diameter. The relatively smooth but nodular variegated surface is seen on the left, and the cut surface on the right. The cut surface has a mucoid glistening variegated appearence characteristic of myxomatous tumors. •This is a solid mass lesion, but some cardiac myxomas have a delicate papillary form similar to a sea anemone. The individual papillae can break off, embolize, and thereby call attention to the possible presence of a cardiac myxoma, among other possibilities. (Description By:J.
