Primary Endometrial High Grade Neuroendocrine Carcinoma: A Case Report with Cytological, Histopathological and Immunohistochemical Features

摘要

An 84-year-old woman suffered from post-menopausal genital bleeding for 3 months. 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.
