Chest computed tomogram (CT) was remarkable for diffuse bilateral nodular infiltrates, more prominent in bases, and mediastinal lymphadenopathy (Figures 1, 2).

Pathological examination. Hemotoxylin and eosin. A case of pulmonary fungal infection with Pseudallescheria boydii. Areas of necrosis within the lung demonstrate numerous septate hyphae with acute angle branching. These hyphal forms are morphologically indistinguishable from Aspergillus spp. on H&E or GMS stain.

The BAL showed many pseudohyphae which were subsequently identified as p. boydii (Figures 3-5).
Pathological examination. Gomori methenamine-silver. The same area of necrosis in the lung as figure Pb1. This GMS stain highlights the morphology of the fungus in this patient infected with Pseudallescheria boydii.
