Xp11 translocation renal cell carcinoma with morphological features mimicking multilocular cystic renal neoplasm of low malignant potential: a series of six cases with molecular analysis.

Here, we introduce a relatively inertia-variant of Xp11 translocation RCC which mimics MCRN-LMP. The distinctive morphological condition is linked to MED15-TFE3 gene fusion. In fact, renal neoplasms with morphological features of MCRN-LMP, especially those containing psammoma bodies, should be routinely evaluated for evidence of TFE3 gene rearrangements.
