[Subcutaneous metastasis of an atrial myxoma? Case report and literature review].

Abstract

A 25 year old woman developed 2 subcutaneous myxomas one month after removal of an atrial myxoma. The pathogenesis of this event is discussed. Special attention was given to distinction between true myxomas and myxoid sarcomas as well as to myxomatous diathesis, caused by a widespread, genetically determined specific abnormality of certain mesenchymal cells (Swiss-syndrome). With all aspects considered, this appears to be the best interpretation of the case under review.
