Neuroendocrine tumor
Midgut NETs are argentaffin positive, can produce high levels of serotonin 5-hydroxytryptamine (5-HT), kinins, prostaglandins, substance P (SP), and other Hindgut NETs are argentaffin negative and rarely secrete 5-HT, 5-HTP, or any other vasoactive peptides. Bone metastases are not uncommon. wikipedia.org

结肠类癌的发病原因？
(二)发病机制在结肠类癌中68%位于右半结肠，其中盲肠占50%，右半结肠与阑尾，空回肠同起源于中肠，其类癌细胞类型65%属亲银性(argentaffin)，35%属嗜银性(argyrophil)，亲银和嗜银细胞区别是：前者分泌5-HT，而嗜银细胞则分泌另一些功能性的活性物质，因而源于中肠的右半结肠类癌在病程晚期或伴有肝转移时可产生类癌综合征
