Renal Mucormycosis: A Rare and Potentially Lethal Complication of Kidney Transplantation
Figure 1
Case A renal allograft histology. Figures 1(a) and 1(b) show renal allograft biopsy indicating broad, pleomorphic, and thin walled fungal small fragments and hyphae with right angle branching and mucoid feature in presence of tissue necrosis consistent with mucormycosis in hematoxylin and eosin stain (a) and Gomori’s methenamine silver stain (b). Explanted allograft kidney demonstrates diffuse and invasive mucormycosis predominantly involving the medulla noted by low magnification in (c) and high magnification in (d) on H&E stain; no mucormycetes invasion of renal artery (e) and vein (f); mucormycetes invasion in proximal portion of ureter indicative of donor ureter (g), and no mucormycetes invasion in distal portion of ureter indicative of recipient ureter (h).
