BACKGROUND Neuroendocrine breast cancer is a rare entity that was defined in 2003 by the World Health Organization as a separate breast cancer subtype. The diagnosis of neuroendocrine breast cancer requires the presence of neuroendocrine features in at least 50% of malignant cells, the exclusion of non-mammary primary tumors, as well as the presence of an in situ component in breast histology. ...

Large cell neuroendocrine carcinoma of the ampulla of Vater is extremely rare. A 55 year old woman presented with an ampullary tumour causing pancreaticobiliary obstruction and a pancreaticoduodenectomy was performed. Microscopically, the tumour was diagnosed as a CD117 positive large cell neuroendocrine carcinoma with glandular differentiation. Four months later the patient developed a general...

We describe a rare hepatic collision tumor composed of a hepatocellular carcinoma and a high-grade neuroendocrine carcinoma. The patient, a 68-year-old man, underwent a partial hepatectomy because of a 4.0 cm mass. The tumor had two distinctive patterns. The majority of the tumor was a high-grade neuroendocrine carcinoma with features of a small cell carcinoma that was positive for chromogranin...

Introduction/Background Gynecologic neuroendocrine carcinomas are rare, aggressive malignancies. The most common site is the cervix followed by endometrium, ovary, vagina and vulva. Histological subtype of origin major prognostic factors. We sought to characterize cytomorphological features these malignancies compare them with histologic features. Methodology Institutional dat...

BACKGROUND There are few reports about the factor influencing the prognosis of high-grade neuroendocrine carcinoma. In this study, we evaluated surgical outcome of clinical stage I high-grade neuroendocrine carcinoma. METHODS Patients who underwent curative surgery for high-grade neuroendocrine tumors of the lung in clinical stage I were included in this study. We retrospectively analyzed 27 ...

There are several differences between neuroendocrine and other types of cervical cancer, in prognosis, diagnosis and treatment. Neuroendocrine cancer of the uterine cervix is a rare and aggressive disease. Small cell carcinoma is classified as a neuroendocrine tumor in the currently used World Health Organization histological classification of tumors of the uterine cervix (2003). Small-cell car...

We describe an unusual case of a 50-year-old female patient developing two primary cancers with neuroendocrine features. Initially the patient underwent surgery for an entero-pancreatic neuroendocrine carcinoma. During the subsequent follow-up she experienced some episodes of vaginal bleeding with negative PET scanning with the tracer fluorine-18 (F-18) fluorodeoxyglucose (FDG). A Papanicolaou ...

Some breast neoplasms are classified as primary neuroendocrine carcinomas because they are positive for neuroendocrine markers. Although neuroendocrine carcinomas can originate from various organs of the body, primary neuroendocrine carcinomas of the breast are extremely rare. The diagnosis of primary neuroendocrine carcinoma of the breast can only be made if nonmammary sites are confidently ex...

Objective: To present a series of neuroendocrine cervical carcinoma, rare malignancy the cervix with different stages, treatment approach and outcome. It is included in this article review about diagnostic approach, prognosis dealing carcinoma. 
 Methods: Case report Cases: We reported three cases First 40-year old woman para 2, stage IIIB carcinoma chose palliative care only. Second, 54-y...
