Synchronous Clear Cell Renal Cell Carcinoma And Tubulocystic Renal Cell Carcinoma

ABSTRACT

Tubulocystic renal cell carcinoma (TCRCC) is a recently described rare subtype of RCC. To best of our knowledge less than 70 cases have been reported till date. The concurrent papillary RCC (PRCC) and TCRCC has been documented in literature, but the co-occurrence of clear cell RCC (CCRCC) and TCRCC is very rare. We are describing a rare case of incidentally detected TCRCC occurring with CCRCC in a 45 years old male who presented with high grade fever with chills and rigors. Grossly, there were two distinct tumors in the total nephrectomy specimen. The larger tumor displayed the histopathological features of CCRCC and the smaller tumor revealed the features of TCRCC.treatment in the present case.
