Atypical and unusual atrial myxoma.

A successfully excised right atrial myxoma arising from the suprahepatic segment of the inferior vena cava associated with asplenia, cutaneous manifestations, and iron deficiency anemia is reported. This report documents the unusual origin of myxoma, along with asplenia. A thorough review of the literature revealed only one other patient with right atrial myxoma originating from the suprahepatic inferior vena cava. Nevertheless, the literature contains no report of any other patient with asplenia associated with atrial myxoma.
