| ABSTRACT |  |
| Ectopic kidneys are a rare congenital anomaly where the kidney is located outside its normal position, and renal cysts in these ectopic kidneys are even more uncommon. The authors report a unique case of a left ectopic kidney with a cystic lesion containing Liesegang rings, a rare histopathological finding. A 47-year-old female presented with intermittent abdominal pain for about two months and was found to have an abnormal renal position on imaging studies. Further investigation revealed a left ectopic kidney with a cystic mass. Surgical excision of the cyst was performed, and histopathological examination showed characteristic concentric calcifications known as Liesegang Rings (LR). These structures are typically associated with chronic inflammation, cysts, fibrotic tissue, haemorrhagic zones, necrotic areas and fluids, but they are rarely reported in renal cysts, especially in ectopic kidneys. While analysing kidney tissue or cytological specimens, it is crucial to consider their presence, as they can closely mimic various organic and inorganic substances, parasites and malignancies, posing a challenge for accurate diagnosis. |
