Pericardial tamponade associated with myeloid metaplasia.
A 32-year-old white male with agnogenic myeloid metaplasia developed pericardial tamponade shortly after elective splenectomy. Tamponade was relieved by pericardiocentesis but recurred, necessitating partial pericardiectomy. Following surgery and a course of radiation therapy to the heart, there was no further significant reaccumulation of fluid. Pathologic evaluation demonstrated foci of extramedullary hematopoiesis in the pericardium. To our knowledge, pericardial tamponade has not previously been reported as a biopsy-proven complication of myeloid metaplasia.
