[Carcinoid neoplasms: report of 5 personal cases].

The authors report 5 cases of carcinoid tumor differently located. The typical carcinoid syndrome has been observed only in one case, presenting with high levels of urinary serotonin and 5-OH-HIAA. The remnant patients were completely asymptomatic and the correct diagnosis was obtained only by histologic examination of the surgical specimen. On the basis of their experience and of the literature, the authors evaluate the current diagnostic and therapeutic options for these neoplasms. The indication for surgical treatment, even in cases with local or distant metastases, is emphasized.
