Mesenteric extraovarian Sertoli-Leydig cell tumor without DICER1 hotspot mutation: a case report

Background Ovarian Sertoli-Leydig cell tumors (SLCTs) with androgenic manifestations harbor DICER1 mutations in 30–60% of cases. Ovarian SLCTs without DICER1 hotspot mutations have been reported to exhibit elderly onset and no androgenic manifestations. We present the first case of a primary mesenteric SLCT without DICER1 hotspot mutation.
