Table 1 Comparison of the morphological difference between kidney CDC in this case and anemic infarct of kidney

From: Renal collecting duct carcinoma with extensive coagulative necrosis mimicking anemic infarct: report of a case and the literature review

  Collecting duct carcinoma (CDC) of kidney in this case Anemic infarct of kidney
Gross morphology A firm grayish yellowish, solid and cystic nodule with irregular borders and extensive geographic coagulative necrosis One or more wedge-shaped necrotic foci, with the occluded vessel at the apex and the periphery of the kidney forming the base
Histological features Atypical tubules or angulated glands around the coagulative necrotic foci, irregularly infiltrate the renal parenchyma with a prominent interstitial growth pattern; Tumor cells have moderate to abundant eosinophilic or clear cytoplasm and large hyperchromatic nuclei with high nuclear grade Coagulative necrosis with the contour of the necrotic tissue with no cellular atypical features
