Multiple myeloma involving the myocardium and coronary vessels.

We report a case of metastatic plasmacytoma to the myocardium and coronary vessels in a 57-year-old man with multiple myeloma. Originally, the patient had a large plasmacytoma in his left chest wall and lung. He received local radiation and chemotherapy. Subsequently, the patient presented with symptoms of congestive heart failure. He had no prior history of cardiac disease. The patient was treated medically and later died from respiratory failure. At autopsy, a metastatic plasmacytoma was identified within the myocardium and externally compressing the coronary arteries. The tumor infiltrated into the coronary sinus. It is difficult to speculate whether the patient's symptoms were due to cardiac involvement since the tumor burden in his chest was also considerable. To our knowledge, coronary vessel involvement with plasmacytoma has not been previously described.

Acute pulmonary embolism triggered by the act of defecation.

Pulmonary embolism associated with the act of defecation has not been previously well described. Recently, we reported our experience with four patients who presented to us over a 12-month period with syncope, near syncope, or sudden death following the act of defecation. In all four cases, acute pulmonary embolism was shown to be the etiology of the defecation-associated events. A retrospective chart review of all patients with the diagnosis of pulmonary embolism at our institution over a three-year period yielded five additional patients with the diagnosis of defecation-associated pulmonary embolism. These nine patients accounted for 6.8 percent of all patients with a discharge diagnosis of pulmonary embolism seen at our institution during the three-year study period. Six of the nine patients died from their defecation-associated pulmonary embolism. These six deaths accounted for 25 percent of all deaths from pulmonary embolism seen at our institution during the study period. Based on our experience, we suggest that the act of defecation may trigger the development of acute pulmonary embolism in some patients with deep vein thrombosis.
