Kidney - Nephroblastematosis

    Narrative
    Kidney - Nephroblastematosis in a female Harlan Sprague-Dawley rat from a subchronic study. An area of dense basophilic cellularity can be seen in the renal cortex.

    Kidney - Nephroblastematosis in a female Harlan Sprague-Dawley rat from a subchronic study. The cells are deeply basophilic and uniform in morphology. They are infiltrating between renal tubules, and no organoid differentiation of the lesion can be recognized.

    Kidney - Nephroblastematosis in a female Harlan Sprague-Dawley rat from a subchronic study. At higher magnification, the cells in nephroblastematosis have indistinct cell margins and cytoplasm, round to oval nuclei with stippled chromatin, and often a prominent nucleolus.

    Kidney - Infiltration, Cellular, Mononuclear in a female Harlan Sprague-Dawley rat from a subchronic study. This higher magnification of mononuclear cell infiltration, characterized by a heterogeneous population of cells in the kidney and small blood vessels, is for comparison with Figures 1 - 3.
