NEUROENDOCRINE BREAST TUMOUR: A CHALLENGING ENTITY TUMOR NEUROENDOCRINO DE MAMA: UNA ENTIDAD DESAFIANTE Neuroendocrine breast carcinoma is a rare type of breast cancer with neuroendocrine differentiation which is found in around 2-5% of all invasive breast carcinomas. In most cases it is a challenge to get to the right diagnosis due to the sporadic number of cases and the need for special immunochemistry techniques, which are not routinely used. Due to the rare number of cases, it is difficult to update guidelines so that the correct diagnosis and treatment is decided. Our purpose is to presen

Correctly diagnosing a histologic type of lung cancer is important for selecting the appropriate treatment because the aggressiveness, chemotherapy regimen, surgical approach, and prognosis vary significantly among histologic types. Pulmonary NETs, which are characterized by neuroendocrine morphologies, represent approximately 20% of all lung cancers. In particular, high-grade neuroendocrine tumors (small cell lung cancer and large cell neuroendocrine tumor) are highly proliferative cancers that have a poorer prognosis than other non-small cell lung cancers.

Recent studies showed that INSM1 is increasingly used as a diagnostic marker for cancers of neuroendocrine origin, since it is highly sensitive and specific.

According to the Global Cancer Observatory, 3.1% of new cancer cases consists of esophageal cancer and 5.5% of deaths was due to esophageal cancer. Histologic classification comprises of either squamous cell carcinoma (SCC) or Adenocarcinoma. Other types are reported to be uncommon. We present a case of 33-year old male admitted due to progressive dysphagia. He underwent esophagogastric resection and histopathologic studies revealed a mixed neuroendocrine- non-neuroendocrine tumor. He rece

Prostate cancer remains the second leading cause of cancer death in men in the USA and most western countries. Prostatic acinar adenocarcinoma is the most commonly diagnosed form of prostate cancer. Small-cell neuroendocrine carcinoma is less frequently identified at the time of initial diagnosis, but this highly aggressive form of prostate cancer is increasingly observed in patients who have failed first- and second-line hormone therapy. Thus, developing and exploring models of neuroendocrine prostate cancer (NePC) are of increasing importance. This review examines the relevant xenograft tumo

Neuroendocrine neoplasia is described in almost every tissue, either in the pure endocrine organs, the nerve structures or in the so-called diffuse neuroendocrine system. The current nomenclature contains time-honored, widely accepted definitions; however, it is different according to anatomical sites. Diverse definitions may generate confusion and non-standard patient management. The International Agency for Research on Cancer – World Health Organization (IARC-WHO) proposed a framework for universal classification of neuroendocrine neoplasia. Evidence indicates that neuroendocrine cancer is c

Paraffin sections from fetal, infantile, and adult nonneoplastic lung tissues were also examined.Results.—In the fetal airway epithelium, β III staining is detected transiently in rare Kulchitsky-like cells from lung tissues co

Being a very rare histopathological type, neuroendocrine tumors are rather aggressive tumors that are usually diagnosed at an advanced stage. Neuroendocrine bladder tumor represents less than 1% of all bladder cancers. Though diagnosed in similar age period of 6th to 8th decade like urothelial carcinoma, its histopathological features and its poor prognosis are apart and rather similar to the small cell cancer of the lung. In this case report, we present a case of high-grade small cell neuroendocrine carcinoma of bladder in an elderly man.

Neuroendocrine prostate cancer (NEPC) represents a variant of prostate cancer that occurs in response to treatment resistance or, to a much lesser extent, de novo. Unravelling the molecular mechanisms behind transdifferentiation of cancer cells to neuroendocrine-like cancer cells is essential for development of new treatment opportunities. This review focuses on summarizing the role of small molecules, predominantly microRNAs, in this phenomenon. A published literature search was performed to identify microRNAs, which are reported and experimentally validated to modulate neuroendocrine markers

Small cell lung cancer is distinguished from other lung cancer histologic types by possessing a variety of neuroendocrine properties. Anti-Leu-7 is a monoclonal antibody that recognizes a 110,000-dalton molecular weight glycoprotein initially described on natural killer cells and subsequently reported on a variety of normal and malignant neural and neuroendocrine cell types. We have found intense anti-Leu-7 binding to a large number of small cell lung cancers, while other lung cancer types were negative or showed only weak and focal binding.

Gastrointestinal Neuroendocrine Tumors (GI-NET) are one of the rarest cancers that occur with an annual global incidence of 2.5-5/100000 patients. Gastrointestinal NeT is the second cancer that affects any individuals, after cancer of the colorectal region. Early identification and early intervention will prevent the mortality of individuals dying due to gastrointestinal neuroendocrine tumors. The main element of prevention is early identification; hence clinicians can identify the rarest cases and can receive enlighten insights to reduce the mortality due to the rarest diseases.
