title: Right atrial myxoma arising from the Eustachian valve in a patient with colonic polyposis.
abstract: Right atrial myxoma arising from the Eustachian valve is rare, with only two reported cases; moreover, any association with colonic polyps is uncommon, with only one such case documented. A case is described of a 68-year-old male who presented with chronic anemia; an initial investigation revealed colonic polyps, but anemia persisted after polypectomy. Further investigation revealed a right atrial myxoma arising from the Eustachian valve and prolapsing into the right ventricle through the tricuspid valve. After successful removal of the lesion, hematological indices returned to normal. In cases of persisting anemia, other rare causes such as atrial myxoma should be sought.
