1 Case 1. Case 1. (A) Low power photomicrograph of renal medulla showing a poorly formed granuloma with several disrupted and destroyed renal tubules within the centre of the granuloma. (B, C) Higher power photomicrographs showing the histiocytes forming a granuloma intimately associated with the disrupted and destroyed renal tubules. (D) Low power photomicrograph showing renal cortical tubules elsewhere within the same biopsy, which appeared unremarkable. A mild interstitial lymphocytic nephritis is present. A Mahmood et al.
