This photomicrograph of a Jones silver stain is interesting in that it shows two findings. First, at 10 o’clock an area of hyalinosis at the perihilar region is present and compatible with perihilar focal segmental glomerulosclerosis.

As suspected, extensive accumulation of intra-podocyte myeloid bodies (a.k.a. zebra bodies, myelinosomes) are seen in all podocyte cell bodies examined (see image below). And, subsequent testing revealed Fabry disease in this patient.

These photomicrographs show a membranous pattern glomerulopathy with C3 staining by immunofluorescence. While it is tempting to diagnosis this as C3 glomerulopathy, that is not correct in this case.
