We report placental cryptococcosis in a woman with multidrug resistant human immunodeficiency virus (HIV) infection. She received antifungal therapy for cryptococcal meningitis prior to delivery. Cesarean section was performed with delivery of a single full-term male infant. There was no evidence of HIV or cryptococcal infection in the infant. The placenta grossly showed multiple white nodules. Microscopically, numerous encapsulated budding yeasts, morphologically consistent with cryptococci, were identified in the intervillous space and, to a lesser extent, in the chorionic villi. Cryptococcal infections are not uncommon, but only 2 cases of placental cryptococcosis have been reported. Our case is the 1st account documenting cryptococcal organisms within the chorionic villi, and yet there was no evidence of infection in the infant. Mother-to-fetal transmission of cryptococcal infection is not well defined. We review the literature and discuss its possible mechanisms.
