INTRODUCTION Intraductal papillary mucinous neoplasm is an uncommon cystic tumor of pancreas that can be associated with ductal adenocarcinoma. Coexistence of pancreatic IPMN and neuroendocrine tumor is very rare. Here, we report the imaging features of mixed type intraductal papillary mucinous neoplasia of the pancreas with high grade dysplasia together with neuroendocrine carcinoma and perfor...

The neuroendocrine status of prostatic adenocarcinomas is considered a prognostic indicator for development of aggressive, androgen-independent disease. Neuroendocrine-like cells are thought to function by providing growth and survival signals to surrounding tumor cells, particularly following androgen ablation therapy. To test this hypothesis directly, LNCaP cells were engineered to inducibly ...

Sinonasal intestinal-type adenocarcinomas (ITACs) are rare neoplasms histologically resembling intestinal adenocarcinomas. Although a neuroendocrine differentiation in ITACs has been described, true mixed exocrine-neuroendocrine carcinomas, neoplasms in which each component represents at least 30 % of the lesion, are extremely rare and their molecular alterations are largely unknown. We describ...

INTRODUCTION A neuroendocrine tumor has known as a neuroendocrine system tumor. Rarely, neuroendocrines have found in other areas, like the liver, gallbladder, bile ducts, kidneys, ovaries or testicles. CASE PRESENTATION We have a 41-year-old woman has referred to our medical center, complaining of fullness and vague pain on her right upper quadrant. The liver scan, sonography, MRI demonstrat...

BACKGROUND Endoscopic treatment for duodenal bulb neuroendocrine tumor larger than 10 mm is still controversial. This report presents four cases successfully treated with endosonography (EUS)-assisted endoscopic mucosal resection (EMR) procedure for duodenal bulb neuroendocrine tumor larger than 10 mm in diameter. METHODS The case series of four patients diagnosed with neuroendocrine tumor fr...

Neuroendocrine tumours (NETs) are rare and heterogeneous neoplasms with variable bio‐ logical behaviour. The estimated incidence of NETs is about 1-5 cases/100,000/year. The most recent data show a progressive increase of the incidence in the last years and a high increase of their prevalence and survival [1]. NETs can be sporadic or can arise in complex hereditary endocrine disorders such as M...

Primary neuroendocrine carcinoma of the breast is a rare entity, comprising <1% of breast carcinomas. Described here is the case of a 78-year-old woman who developed an invasive tumor in the left breast measuring 2.0 cm x 1.5 cm x 1.2 cm. The tumor was composed of only endocrine elements in the invasive part. It infiltrated in a nested fashion with no tubular formation. Intraductal components w...

This study aimed to explore the clinicopathological characteristics and differential diagnosis of primary neuroendocrine tumor (G1) of the testis. In this paper, we analyze the clinical, histomorphological and immunohistochemical findings, treatment and prognosis of a patient with primary neuroendocrine tumor of the testis, and discuss the relevant literature. A 52-year-old man presented with a...

The appendixis the second primary site for neuroendocrine tumors. The management of incidentelly discovered neuroendocrine tumor of the appendiceal base less than 20 mm in diameter is still controversal. The aim of this study was to discuss the management of such tumors. Three patients were operated on for acute appendicitis. Histopathologic examination of surgery specimens revealed neuroendocr...

Uterine perivascular epithelioid cell tumor is a rare mesenchymal consisting of histologically and immunohistochemically distinctive cells. These tumors’ being rare, having different morphological features similar immunohistochemical expression findings to that some tumors lead diagnostic difficulties misdiagnoses. In the present case report, we aimed discuss traps fell into while diagnosing cu...
