[An association of mucocele and carcinoid tumour of the appendix]

The carcinoid tumour of the appendix and the mucocele are entities rather infrequent in children and are normally diagnosed in the course of an appendicectomy that is, in most of the cases, curative. The association of both processes is unusual. The authors present a case of carcinoid tumour of the appendix associated to mucocele in a male, aged 10 patient, who underwent an appendicectomy by suspicion of an acute appendicitis. The histologic study confirmed the presence of a mucocele of the appendix associated to a carcinoid tumour with a 0,7 cm diameter. The serum serotonin and chromogranin A assessment was normal, and the TAC and colonoscopic examination resulted in no meaningful findings. The appendicectomy itself was curative, deeming it the appropiated treatment in tumours under 2 cm diameter.
