 Xp11.2 translocation renal cell carcinoma (Xp11.2 RCC) with PSF-TFE3 gene fusion is a rare neoplasm.     ///    A case of PSF-TFE3 gene fusion in Xp11.2 renal cell carcinoma with melanotic features..     ///    We describe an additional case of Xp11.2 RCC with PSF-TFE3 showing melanotic features.     ///    Xp11.2 RCC with PSF-TFE3 inevitably requires differentiation from other kidney neoplasms.     ///    Only 22 cases of Xp11.2 RCCs with PSF-TFE3 have been reported to date.     ///    "Genetically, we demonstrated PSF-TFE3 fusion between exon 9 of PSF and exon 5 of TFE3.
