Case report: A middle age male presented with pain in left flank and decreased urine output. CECT Abdomen revealed a well defined solid cystic mass lesion arising from inferior polar cortex of the left kidney measuring 10.9 x 9.4 x 9.8 cm. Left radical nephrectomy was performed and the specimen was sent for histopathological examination and show features of oncocytic variant of papillary renal cell carcinoma.

Conclusion: The importance of this case report is to identify the rare variants of the histological subtypes of RCC as it confers high propensity of metastasis and hence less chance of survival. OPRCC is regarded as an independent subtype of PRCC not only for its distinct pathological features but also for its indolent clinical behaviour and the tumor presents with same immunophenotypic as of type 2 but same genetic features and prognosis as of type 1 PRCC.
