CARCINOID
The
cell of origin of carcinoids is the Kultschitzky cells
and
the
cytoplasmic granules of the cell stain with silver staining
and thus these lesions are also named
"argentaffin tumors".
Carcinoid tumours
can occur anywhere in the gastrointestinal
tract
where the Kultschitzky cells occur from gastric cardia to
anus.
Appendix is most frequently involved
(46%)
*
followed by ileum (28%) and rectum (17%)
*
other locations are stomach, gallbladder, duodenum, jejunum.
Malignant Carcinoid Syndrome is
manifested by cutaenous flushing:
*
hyper-peristalsis
*
diarrhoea
*
asthma and
*
haemodynamic alterations that may result in vesomotor collapse
These
effects are produced by the
vasoactive products of the
carcinoid (5 hydroxytriptamine).
