TFE3 and hereditary clear cell renal cell carcinoma: Throughout history, different morphological subtypes have been described regarding cytological or architectural features (e.g., clear cell renal cell carcinoma—ccRCC, papillary RCC, chromophobe RCC), and with the advancement of molecular techniques, new, molecularly defined entities have emerged (e.g., TFE3-rearranged renal cell carcinoma, succinate dehydrogenase-deficient renal cell carcinoma, ALK-rearranged renal cell carcinoma) [2].
