This is the first reported case of double primary cardiac tumors (leiomyosarcoma and myxoma) in collision.
Silent cardiac metastasis in leiomyosarcoma may evade detection; first collision tumor case leaves open the spectrum of dual cardiac primaries.
An autopsy case of a primary cardiac leiomyosarcoma of the left atrium colliding with a myxoma in the same chamber was presented. Cardiac signs and symptoms were remarkably silent. She died with multiple systemic metastasis of the leiomyosarcoma. As far as we are aware of, this is the first report of a case with double primary cardiac tumors in collision.
