102. Using cytogenomics to distinguish two types of renal cell carcinoma in a composite or collision tumor

The coexistence of phenotypically and genotypically distinct tumors within a single lesion is rare and may indicate a collision (two separate origins) or composite (common origin) tumor. This phenomenon in the kidneys may include benign and malignant tumor types including metastasis from elsewhere in the body. Collision and composite tumors of two different renal cell carcinoma subtypes is exceedingly rare. Here we present a case of a 46-year-old male patient who underwent a partial nephrectomy due to a renal mass identified by CT scan.
