Abstract
The usual tissue form of G. capsulatum is a small intracellular yeast, though extracellular organisms of unusually large size are described. The production of hyphae in tissue is regarded as rare and not generally appreciated. A case of probable H. endocarditis from which an embolus demonstrated abundant mycelial forms on histologic examination is reported. Of the previously reported cases of H. capsulatum endocarditis with detailed pathologic description, 9 of 27 cases are found to demonstrate hyphal forms. Hyphal structures should be considered a common morphologic variant of H. capsulatum in intravascular lesions.
