The sections show multiple large cortical cysts. There is relative sparing of the parenchyma in the lower pole. The cyst walls are fibrotic, contain parenchymal remnants and have foci of calcifications. The cyst lining consists of flatted epithelium without appreciable cytoplasm. No cyst lining cell atypia is present. The cyst lining cells are POSITIVE for AE1/AE3 and NEGATIVE for CD34. | |||
Comment: | |||
It is noted that the contralateral kidney is unremarkable on imaging. The findings are in keeping with localized cystic disease of the kidney, a rare benign finding that can mimic a tumour.[1] | |||
