| ABSTRACT |  |
| A collision tumour is characterised by the co-existence of two adjacent but different tumour types, with no histological admixture, forming a single lesion. This case report presents a case of a 46-year-old female with a solitary tumour in the lower pole of the left kidney. A left lower polar partial nephrectomy was done. Histologically, the tumour had two distinct but closely associated tumour components, the first one was a conventional clear cell Renal Cell Carcinoma (RCC) and the second component a papillary RCC. The final diagnosis was a collision tumour consisting of clear cell RCC and papillary RCC. A collision tumour of two different RCC subtypes is exceedingly rare and only a few cases have been published until now. Hence, this article presents the case report due to the rarity of its occurrence. |
