Primary primitive neuroectodermal tumor of the uterus: a case report

Abstract

Neuroendocrine carcinomas primitive neuroectodermal tumor (PNET) arise from Kulchitsky cells and are frequently seen in gastrointestinal tract and lungs. But they are unusual in gynecology practice. We presented a case of PNET arising in the uterine corpus of a 22-year-old woman. To our knowledge, this is the first description of small-cell carcinoma of the uterine corpus with a pseudocyst formation within the myometrium without endometrial invasion.
