Based on the endometrial cytological findings (suggestive of high grade neuroendocrine carcinoma) showing that there were rosette-like and cord-like structures consisting of small rounded tumor cells with oval nuclei and scanty cytoplasm, radical hysterectomy was performed. Histopathological and immunohistochemical examinations on the operated specimens revealed primary high grade neuroendocrine carcinoma of the endometrium. Despite the extensive treatment against the malignancy, the patient died due to widespread metastases after 5 months after the surgery and autopsied. %K Endometrium %K High Grade Neuroendocrine Carcinoma %K Undifferentiated Carcinoma %K Neuroendocrine Cells %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=53028
