Diagnosing symptomatic or incidental renal masses increased with the advances in technology. Renal cell carcinoma (RCC) is the most common type of kidney cancer. Papillary RCC is the second most subtype of RCC. Renal oncocytoma is a benign epithelial tumor of kidney and is the second most common benign tumor after angiomyolipoma. Hybrid tumors of oncocytoma and chromophobe RCC are known in the literature. However, primary renal collision tumors are rare neoplasms those composed of two different cell lineages. We present a rare entity as a case report which is oncocytoma with renal papillary cell cancer Type 1.

Keywords: Collision tumor, laparoscopic partial nephrectomy, oncocytoma, papillary renal cell cancer, renal cancer.
