A patient rapidly developing right heart failure due to a left-atrial leiomyosarcoma
was admitted for surgery. A large tumor, originating in the left atrium and extending
into both pulmonary veins, was removed. Histology showed an unusual epitheloid appearance
of many cells with occasional mitoses and a strong immunexpression to desmin and actin.
Six months later heart failure developed again: computer tomography demonstrated regrowth
of the tumor in the left atrium with invasion of the mediastinum and the para-aortal
lymph nodes. The patient died shortly after.
