The advent of electron microscopy has repeatedly confirmed Whipple's original postulate that bacterial infestation might be the cause of intestinal lipodystrophy (Whipple's disease). We have recently studied two patients, a 67-year-old man and a 38-year-old woman, who died of untreated Whipple's disease, and both were found to have clinically unrecognized pancarditis. Histologically, PAS-positive histiocytes in foci of chronic inflammation were demonstrable in several organs, including the heart. Electron microscopy of autopsy tissues showed numerous intracellular and extracellular rod-shaped bacillary bodies and serpiginous membranes. The bacillary bodies, some sectioned transversely and others longitudinally, were about 0.2 mum wide and 2 mum long; each had a double-layered cell wall. These bacillary bodies have not been previously identified in the heart, and may be casually related to cardiac lesions occurring in many untreated cases of Whipple's disease.
