(A) Low-power view showing diffuse and severe interstitial cell infiltration (PAS, original magnification ×100). (B and C) Low-power view showing granulomatous interstitial inflammation with mononuclear and epithelioid cells. There were focal isolated multinucleated Langhans giant cells in the interstitium. Glomeruli are collapsed (PAS and periodic acid silver methenamine, original magnification ×200). (D) High-power view of GMS stain showing multiple small, rounded yeast-like features and branching filamentous features in the interstitium. These organisms were diagnosed as Candida albicans by PCR-based detection (GMS, original magnification, ×400).
