Neuroendocrine neoplasms are an important subcategory of tumours encountered in gastrointestinal tract and lung. Previously known as
'Carcinoid tumours', Considerable confusions prevailed regarding the nomenclature, diagnostic categories as well as prognostic classication of
this group of tumours; until recently, in 2018, a uniform framework of classication was attempted by WHO. Here, we discuss nine cases of
neuroendocrine neoplasms of GI tract diagnosed in our Institution over past two years, focussing on the application of this classication system, the
key concepts behind it and also the points to be addressed in critical scenarios while making a diagnosis. A fascinating case of coexistent
neuroendocrine carcinoma and intestinal tuberculosis is specially highlighted in this article, as probably, it is the rst case reported of its genre till
now, as far our knowledge goes.
