MANTILLA, Julio Cesar; GARCIA, María Emma  and  CASTILLO, Mario Alberto. Carcinoid tumor of the cecal appendix: A report of four cases in the Clinica Carlos Ardila Lulle, Floridablanca, Colombia. Rev. Univ. Ind. Santander. Salud [online]. 2011, vol.43, n.2, pp.203-210. ISSN 0121-0807.

Introduction: The carcinoids tumours are the most common neoplasm of the cecal appendix, are characterized by a slow growth and asymptomatic clinical course, its incidence is estimated at 1-2 cases per 100.000 inhabitants, are less than 1% of appendicectomies and occur most often in women between the fourth o fifth decade of life. Usually these are small lesions diagnosed after appendicectomy. Methodology: This work belongs to a description of cases of carcinoid tumor of cecal appendix, conduced in the MEGA anatomic pathology laboratory of Carlos Ardila Lulle Clinic (CAL), wich includes protocols review of surgical specimens analized between January 1, 2000 and December 31, 2010. Results: During the proposed period are four cases of carcinoid tumor confined to the cecal appendix in four young women. Three of the lesions have the A histological type or insular pattern, and the remainder have the B histological type or trabecular pattern, in all cases documented reactivity with silver salts with Masson-Fontana stain and all four were found positive with the neuroendocrine marker chromogragin. Conclusion: The carcinoid tumors of the apenddix are lesions of neuroendocrine origen, most of them located at the tip of the organ, and having a indolent clinical course; however some of these tumors have an aggressive behavior, which depends on its size and the mitotic activity of its cells, that's the reason why the diagnostic evaluation of neuroendocrine markers like chromogranin, and Ki67 (proliferation cell index) are recommended.
