Fig. 2From: Primary Xp11 translocation PEComa of the testis with SFPQ⁃TFE3 rearrangement: a case report and review of the literatureThe tumor cells were diffusely strongly positive for cathepsin K (A) and HMB45 (B). (C) The tumor nuclei were diffusely strongly positive for TFE3. (D) The fusion probe assay using probes centromeric to PSF and telomeric to TFE3 indicated an abnormal signal pattern consistent with the SFPQ-TFE3 fusionBack to article page
