title: CD30 positive (Ki-1) large cell lymphoma presenting with pericardial constriction.
abstract: It is very uncommon for the initial presentation of malignant lymphoma to be one of cardiac involvement and for such involvement to precipitate cardiac dysfunction attributable to constriction. We describe a CD30 positive (Ki-1) anaplastic large cell lymphoma, T-cell type, in a 29-year-old man whose presentation was a short history of profound hemodynamic impairment and whose clinical course was rapidly fatal. This patient's constrictive physiology was attributable to diffuse infiltration of the pericardium and epicardium by the Ki-1 lymphoma. Our description of this patient is noteworthy, given that the clinical and pathologic features of Ki-1 lymphomas are still being characterized.
