Four years of natural progressive course: A rare case report of juvenile Xp11.2 translocations renal cell carcinoma with TFE3 gene fusion

Abstract

Renal cell carcinoma (RCC) with TFE3 gene fusion caused by Xp11.2 translocations is a rare RCC subtype. This tumor is typically seen in children, comprising 20‒40% of overall RCC cases compared to 1‒1.6% observed in adults. Xp11.2 RCC is associated with a poor prognosis due to both the progression of local lesions and early distant and lymphatic metastasis.
