| Summary: | <p>Background: The clear cell, chromophobe and papillary carcinoma as well as oncocytoma are the most common renal tumours. While cases of hybrid renal tumours are well known, the true collision renal tumour of oncocytoma and Papillary Renal Cell Carcinoma (PRCC) is still rare. Herein, we present a case of a true collision renal tumour of an oncocytoma and a PRCC as well as a review of the literature.</p><p>Case presentation: A 53- year- old man presented with painless macroscopic haematuria and nocturia. While urethrocystoscopy showed no pathological findings of the bladder mucosa, a CT scan of the abdomen and thorax revealed a 12x17x16 cm renal mass. The patient underwent a subcostal transperitoneal radical left sided nephrectomy. Pathological examination revealed a true collision tumour of an oncocytoma and a PRCC; type 1, Fuhrman grade 2 (pT1a). No clinical, laboratory or radiological signs of local recurrence or distant metastases were seen during the nine-year follow-up period. </p><p>Conclusions: According to our and previous case reports, collision renal tumours consisting of an oncocytoma and a PRCC seems to have a good prognosis and does not require a specific follow-up program but rather can follow the standard program for PRCC. </p> |
