Figure 1
Kidney biopsy findings in case 1. (a) The tubules contain densely eosinophilic intraluminal casts with a granular to globular appearance (hematoxylin and eosin stain). (b) The casts are non-argyrophilic and sometimes distend the tubular lumen (Jones methenamine silver stain). (c) Hemoglobin A immunohistochemical stain is strongly positive in the casts.

Figure 2
Kidney biopsy findings in case 2. (a) Numerous eosinophilic intratubular casts are present, some of which have a granular appearance (hematoxylin and eosin stain). (b) Other casts are composed of larger eosinophilic globules (hematoxylin and eosin stain). (c) Hemoglobin A immunohistochemical stain demonstrates that both the granular and globular casts are composed of hemoglobin.
