Molecular cloning using 5' rapid amplification of complementary DNA ends and subsequent reverse transcription-polymerase chain reaction revealed an SFPQ/PSF-TFE3 gene fusion.     ///     We report a case of perivascular epithelioid cell tumor (PEComa) with an SFPQ/PSF-TFE3 gene fusion in a 14-year-old girl treated for adrenal neuroblastoma for 4 years.     ///    "To the best of our knowledge, this is the second reported case of metachronous PEComa subsequent to a primary tumor, and the first report confirming an SFPQ/PSF-TFE3 gene fusion in PEComa.. "    ///    Perivascular epithelioid cell tumor with SFPQ/PSF-TFE3 gene fusion in a patient with advanced neuroblastoma..     ///    "To the best of our knowledge, this is the second reported case of metachronous PEComa subsequent to a primary tumor, and the first report confirming an SFPQ/PSF-TFE3 gene fusion in PEComa.."
