title: Left atrial myxoma infected with Histoplasma capsulatum.
abstract: A patient is presented in whom a left atrial myxoma was found to be infected with Histoplasma capsulatum. Histoplasmosis has not been previously associated with this tumor, nor has any fungus without preceding bacterial endocarditis and long-term antibiotic therapy. The clinical course in foru previously reported cases of bacterially infected myxoma is reviewed. There have been 18 prior cases of Histoplasma endocarditis and in two the patients have survived. Their clinical presentation and response to therapy are also reviewed, and pertinent therapeutic conclusions drawn. The role of echocardiography in this patient's evaluation and the ultimate successful therapy are discussed.
