Carcinoid tumors are relatively uncommon tumors and their presentation
is varied. For these reasons, a high index of suspicion is necessary
in order to consider the diagnosis. It is important to separate the ''
syndrome'' from the primary tumor. It is obviously more effective to d
iagnose the tumor itself before the syndrome manifests itself, usually
as a result of metastatic disease. Since the tumors are characteristi
cally slow-growing, the physician may be misled into thinking the pati
ent has functional problems rather than a tumor. Some data and guideli
nes are given for focusing on the signs and symptoms of carcinoid dise
ase.
