Abstract

Neuroendocrine carcinoma (NEC) of the endometrium is a rare, aggressive subtype of endometrial cancer.  We report a 61-year-old female with a history of breast cancer, s/p modified radical mastectomy, chemotherapy, radiotherapy and hormonal (tamoxifen) therapy, who  presented with post-menopausal bleeding. Patient underwent TAH-BSO with lymph node dissection, and was diagnosed with a mixed small cell neuroendocrine carcinoma (SCNEC) and large cell neuroendocrine carcinoma (LCNEC), confirmed by positive immunohistochemical staining for neuroendocrine markers.  No other lesions were identified on PET-CT, making a primary endometrial NEC the most likely diagnosis.  We review the clinical and pathologic characteristics of endometrial neuroendocrine carcinomas.
