Review of renal carcinoma associated with Xp11.2 translocations/TFE3 gene fusions with focus on pathobiological aspect

Popis výsledku v původním jazyce

The concept of Xp11.2 renal cell carcinoma (RCC) was recently established as a tumor affecting 15% of RCC patients {45 years. Many patients present with advanced stage with frequent lymph node metastases. Histologically, Xp11.2 RCC is characterized by mixed papillary nested/alveolar growth pattern and tumor cells with clear and/or eosinophilic, voluminous cytoplasm. Neoplastic cells show intense nuclear immunoreactivity to TFE3, while focal immunostaining for melanocytic markers, including melanosome-associated antigen or Melan A in some cases, are also noted. Alpha smooth muscle actin and TFEB are consistently negative. Ultrastructurally, the ASPL-TFE3 RCC variant contains rhomboid crystals in the cytoplasm, similar to that observed in alveolar soft part sarcoma. The fusion of the TFE3 gene with several different genes, including ASPL(17q25), PRCC(1q21), PSF(1q34), NonO (Xq12) and CLTC (17q23) have been identified to date. The behavior of Xp11.2 RCC in children and young adults is con
