This autopsy photograph of the kidneys demonstrates the multifocal punctate lesions visible on the serosal surface (arrows). Don't confuse these small yellow punctate lesions with the fat that is adherent to the renal capsule.

This photograph of the cut surface of these kidneys shows that these multifocal punctate lesions are primarily in the cortex (arrows).

Microscopic Pathology

This is a low-power photomicrograph of lymph node with three prominent areas of Candida colonies (arrows). Even at this low magnification, the purple-staining yeast and pseudohyphae can be easily seen. This section was stained with Periodic Acid-Schiff Hematoxylin (PASH), which stains the cell wall of fungi to make them more easily visible.

This is a low-power photomicrograph of one of the Candida colonies from this lymph node. The chains of yeast which are termed "pseudohyphae" are apparent at this magnification.

This higher-power photomicrograph shows the yeasts and pseudohyphae in this focus of Candida organisms.

This high-power photomicrograph shows the yeasts (1) and pseudohyphae (2).

This is a low-power photomicrograph of the kidney from this same case. Note the Candida colonies (arrows). The pseudohyphae are evident around the periphery of these colonies even at this low magnification.

This is a higher-power photomicrograph of a Candida colony in the kidney. Note the pseudohyphae of the Candida organisms.
