We report a rare case of bony involvement by paracoccidioidomycosis in
a 4-year-old boy. Extremity radiographs show a diffuse permeative pat
tern of metaphyseal bony destruction. Although these findings are nons
pecific, they may suggest the disease in an appropriate clinical setti
ng. Definitive diagnosis, however, depends upon detection of Paracocci
dioides braziliensis on laboratory analysis.
