A CASE SERIES OF NEUROENDOCRINE NEOPLASMS OF GASTROINTESTINAL TRACT: A REAPPRAISAL OF NEWER CONCEPT OF THE UPDATED WHO CLASSIFICATION OF NEUROENDOCRINE LESIONS CITING A RARE & FASCINATING CASE OF COEXISTING INTESTINAL TUBERCULOSIS.

Abstract

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 classication of this group of tumours; until recently, in 2018, a uniform framework of classication 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 classication 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.
