In some rare patients, SDH mutations may co-occur with Xp11 translocation RCC, characterized by TFE3 chromosomal translocations involving break points in the TFE3 gene; renal cell carcinomas with translocations make part of MiT family translocation renal cell carcinoma and are composed by eosinophilic cells, with cytoplasmic inclusions and prominent nucleoli [44]. The gene discussed is TFE3; the disease is renal cell adenocarcinoma.
