Histologically, this is a fungus which begins its life cycle as a parasite measuring 8μ, but it grows by nuclear division
The large typical round spores with a thick capsule and centrally placed daughter spores are noted. until it reaches a size of 300μand contains over 4,000 nuclei which form 16,000 spores.3 The mature sporangium presents a double-contoured chitinous envelope. The mode of infection and transmission is unknown.
According to a perusal of the literature, this seems to be the youngest patient ever presented. The
