A case of juvenile-type paracoccidioidomycosis in a pregnant woman is
reported. The disease pre-dated pregnancy and antifungal treatment was
being administered when she became pregnant. A premature male infant
was delivered with no evidence of infection. Microscopic examination o
f the placenta showed numerous Paracoccidioides brasiliensis yeast for
ms in the intervillous space, enmeshed in a macrophagic--phagocytic re
action, with damage of the trophoblastic layer. Placental transfer of
specific P. brasiliensis antibodies was demonstrated.
