Primary zygomycosis of the pericardium in an immunocompetent host

The fungi in the order Mucorales commonly target immunocompromised hosts, especially diabetics and produce fulminating respiratory and/or central nervous system infections, which are often fatal. We report primary zygomycotic pericarditis accompanied by osteomyelitis of the sternum in an immunocompetent female: a rare site and a rare setting. The disease was clinically thought to be of tuberculous aetiology and had evaded diagnosis for a year.
