Abstract excerpt
AIMS: Ovarian Sertoli-Leydig cell tumor (SLCT) with heterologous rhabdomyosarcoma (RMS) is exceptionally rare. While the presence of heterologous elements in SLCT is highly predictive of an underlying DICER1 mutation, the molecular alterations in these tumors, including in SLCTs with heterologous RMS, remain largely unknown. In this study, we aimed to characterize the clinicopathologic features of these rare...
