Printed from Surgical Pathology Criteria: WHO 2010 has changed back to neuroendocrine cell from endocrine cell for these lesions, Endocrine cell hyperplasia and neoplasia are equivalent terms to those used below, Gastric carcinoids and neuroendocrine cell proliferations arise in three settings, Hyperplasia, dysplasia and neoplasia are not uncommon, Most carcinoids are <1 cm and are not aggressive, May not progress even if not resected, Without MEN1, generally only neuroendocrine cell hyperplasia is seen, With MEN1, may have neuroendocrine cell dysplasia and neoplasia, Such carcinoids may behave aggressively, Over half may invade deeply and metastasize, Types of neuroendocrine cell proliferations, Chromogranin and/or synaptophysin stains are necessary for evaluation of neuroendocrine cells, Scattered individually, primarily in the basal crypt epithelium, Linear or micronodular clusters of at least 5 cells, Micronodular clusters 150 microns in greatest dimension, At least 2 linear chains / mm or 1 micronodule / mm, Enlargement and fusion of five or more micronodules, >150 microns in greatest dimension, Microinfiltration of lamina propria, Nodule with formation of new stroma, Nodules 0.5 mm to 0.5 cm have been termed microcarcinoids, Gastric endocrine cell proliferations typically show features seen in other GI tract well differentiated endocrine proliferations, Occasional reports of scattered larger atypical nuclei, Trabecular, acinar, pseudo glandular architecture, Variable positivity for neuroendocrine markers, It has been proposed that type A and B hyperplasia and dysplasia may progress to carcinoid (Berna 2008, Annibale 2001), This is not universally accepted for hyperplastic lesions (Solicia 1995), It would appear that both merit followup, The behavior of carcinoids is dependent upon size, proliferation rate and the setting in which it arises (see, Well differentiated processes including carcinoids, Duodenum NOS and proximal jejunum, Ileum and distal jejunum Bookshelf Less frequently, Caduet causes headache (5%).

Prior to the findings of the hyperplasia of neuroendocrine cells it was known as tachypnea of infancy, as most children outgrow the need for oxygen . There are no specific recommendations for the study of the hormone secretion profile, however, There is very limited data about molecular alterations in colorectal neuroendocrine tumors; most molecular analyses have been performed in pancreatic and small intestine tumors (, Well differentiated neuroendocrine tumor, WHO grade 2 (G2), 7 mm (see comment), Comment: There are 2 mitotic figures in 2 mm, High grade tumors with poorly differentiated morphology, Atypical small or large cells organized in diffuse sheets with little nesting, Apoptotic bodies and necrosis are usually observed, They are high grade by definition (mitoses > 20 per 10 high power fields or, Remember that there are some G3 neuroendocrine tumors; poorly differentiated morphology is the main feature to distinguish neuroendocrine carcinomas from G3 neuroendocrine tumors, CD56 immunostaining is more specific than synaptophysin for its diagnosis, CDX2 expression may indicate the site of origin of this type of tumor, Presence / absence of necrosis is the main feature in defining the tumor grade, Proliferative activity is not relevant in these tumors. It is a non-progressive disease of the interstitial tissues of the lungs. During Caduet drug therapy, a variety of unwanted effects may arise, among which the most common is peripheral edema.
