Everything you ever wanted to know about cancer stem cells in neuroendocrine neoplasms but were afraid to ask.

While the role of cancer stem cells (CSCs) in tumorigenesis, chemoresistance, metastasis, and relapse has been extensively studied in solid tumors, such as adenocarcinomas or sarcomas, the same cannot be said for neuroendocrine neoplasms (NENs). While lagging, CSCs have been described in numerous NENs, including gastrointestinal and pancreatic NENs (PanNENs), and they have been found to play critical roles in tumor initiation, progression, and treatment resistance. However, it seems that there is still skepticism regarding the role of CSCs in NENs, even in light of studies that support the CSC model in these tumors and the therapeutic benefits of targeting them.

The vast majority of neuroendocrine 'neoplasms (NENs) are sporadic, although recent evidence has indicated that a subset of these cancers may also originate as a result of genetic germline mutations. To date, 10% of these cancers can be linked to an inherited genetic syndrome. Genetic diagnosis is crucial for patients with a suspected hereditary NEN syndrome, as it recognizes patients carrying germline mutations and allows for personalized clinical follow-up, considering the higher risk of developing other tumours.

BACKGROUND Neuroendocrine carcinoma (NEC) of the cervix is rare and has high mortality and recurrence rates. The clinical symptoms of cervical NEC, such as abnormal vaginal bleeding and discharge, are similar to those of other cervical cancers. Here, we describe a case involving a 42-year-old woman with cervical NEC accompanied by an isolated large ovarian metastasis.

A 34-year-old male patient with recently diagnosed with medullary thyroid carcinoma underwent total thyroidectomy and radical neck dissection, requiring sharp dissection to separate the tumour from the trachea. He required post operative intubation due to bilateral vocal cord paralysis. He developed ischaemic necrosis of the upper two thirds of the trachea presenting with marked surgical emphysema and an infective wound.

Merkel cell carcinoma (MCC) is an uncommon aggressive neoplasm, usually arising in sun-exposed skin of the head and neck. By immunohistochemistry, KRT20 and MCPyV positivity are found in about 90% and 80% of MCCs, respectively. Noteworthy, viral status in lip/oral cavity MCCs is poorly known.
