Breast neuroendocrine tumours are rare, accounting for up to 5% of all breasts tumours and approximately 1% of all neuroendocrine tumours. In most cases, breast neuroendocrine tumours are histologically and moderately well differentiated. Neuroendocrine breast tumours lack characteristic imaging patterns. The histopathological assessment of these tumours is difficult, and in most cases the corr...

Neuroendocrine tumours belong to a heterogeneous family of neoplasms, originating in endocrine glands (such as the pituitary, parathyroid or the neuroendocrine adrenal glands), in endocrine islets (within the thyroid or pancreas) as well as in endocrine cells dispersed between exocrine cells throughout the digestive or respiratory tracts. The clinical behaviour of neuroendocrine tumours is vari...

Neuroendocrine tumours of lungs represent a subgroup of pulmonary tumours with typical morphofunctional traits. In light microscopy, the four principal types of the tumours (typical and atypical carcinoids, small cell lung cancer, large cell neuroendocrine carcinoma) demonstrate typical arrangement of cells (organoid nesting, palisading, a trabecular pattern, and rosette-like structures), varia...

INTRODUCTION Tumours with adenocarcinoma and neuroendocrine components have often been reported, although the reason underlying the dual components remains unclear. CASE PRESENTATION A 43-year-old woman with multiple liver metastatic lesions of rectal neuroendocrine tumour underwent primary tumour resection and subsequent liver transplantation. Pathological examination indicated a cholangioca...

Background: Neuroendocrine Neoplasms (NEN) represent 60% of all appendicular tumours. This type of cancer is predominantly benign.  In this study, appendicular NEN tumours in children were investigated. Materials and Methods: This retrospective study was conducted on 540 patients underwent emergency appendectomy for the treatment of clinically suspected appendicitis at the department of p...

BACKGROUND Both primary and secondary gynaecological neuroendocrine (NE) tumours are uncommon, and the literature is scarce concerning their imaging features. METHODS This article reviews the epidemiological, clinical and imaging features with pathological correlation of gynaecological NE tumours. RESULTS The clinical features of gynaecological NE tumours are non-specific and depend on the ...

The growing interest in neuroendocrine tumours is due to the dynamic growth of detection of this type of cancer. Neuroendocrine tumours (neuroendocrine neoplasms - NENs / neuroendocrine tumours - NETs) derive from glands, groups of endocrine cells and diffuse neuroendocrine system cells. Mainly they derive from the gastrointestinal tract (gastroenteropancreatic-neuroendocrine tumours - GEP-NETs...

Neuroendocrine tumours are a heterogeneous group including, for example, carcinoid, gastroenteropancreatic neuroendocrine tumours, pituitary tumours, medullary carcinoma of the thyroid and phaeochromocytomas. They have attracted much attention in recent years, both because they are relatively easy to palliate and because they have indicated the chronic effect of the particular hormone elevated....

Neuroendocrine tumours are a heterogonous group of tumours with a wide variety of clinical presentations. They arise from enterochromaffin cells located in neuroendocrine tissue throughout the body. Neuroendocrine tissue is derived from cells which migrated from the neural crest to the gastrointestinal endoderm. There are many types of NETs, phaeochromocytoma’s, small cell carcinoma’s of the lu...
