Primitive neuroectodermal tumor (PNET) arise from Kulchitsky cells and are rarely seen in the female genital tract. Differential diagnosis of PNET can be made based on immunohistochemical profiles and genetic analyses. Genital tract pNETs are very aggressive pathologies with different clinical and molecular manifestations and there are no standard guidelines for treatment. We aimed to present two cases of uterine PNETs with different symptomatology and clinical findings.
