A case of repeated pulmonary embolism in a 10-month-old infant treated with intravenous hyperalimentation for recurrent diarrhea is described. The pulmonary emboli arose from the lesions of Candida endocarditis involving the tricuspid valve and the right ventricle. Candida endocarditis developed as a complication of intravenous hyperalimentation. Pulmonary endarteritis elicited by the Candida organisms in the pulmonary emboli arrested the spread of the organisms into the pulmonary parenchyma and systemic circulation. Electron microscopic features of the C albicans are also briefly described.
