RESUMO
Microphthalmia-associated transcription (MiT) family translocation related renal cell carcinoma (RCC) is an important type of renal cell carcinoma, which was included in the new classification of renal tumors by the World Health Organization (WHO) as an independent subtype in 2016. This type of renal cell carcinoma mainly includes Xp11.2 translocation /TFE3 gene fusions associated with renal cell carcinoma and T (6; 11)(p21; q12)/TFEB gene fusion-associated renal cell carcinoma, which has similar clinical features, histology, immunohistochemistry, and molecular genetics, but is significantly different from other renal cell carcinomas. In this review, the clinicopathology and genetics of MiT family translocation associated renal cell carcinoma were reviewed in order to provide guidance and help to the clinical and pathologic work.
