title: Renal cell carcinoma in a horseshoe kidney: Report of a rare disease.
abstract: A horseshoe kidney (HSK) is the most common congenital renal fusion anomaly. HSKs are more likely than normal kidneys to have associated problems of stones, ureteropelvic junction obstruction, stasis and infection. However, they do not have an increased incidence of renal cell carcinoma when compared to normal kidneys. Due to its rarity, accurate diagnosis may be difficult. Of similar significance is the fact that problems may arise during surgery on these kidneys due to altered anatomy and aberrant blood supply. We report a case of HSK with a renal tumour in a 69-year-old woman and highlight our challenges in the management of the case. To the best of our knowledge, this is the first reported case of a tumour in an HSK in West Africa.
