The tubular type of appendiceal carcinoid is a neoplasm of young
adults that has very good prognosis. The differential diagnosis
includes primary and secondary adenocarcinomas of the appendix.
Two cases of tubular carcinoid found incidentally in appendectomy
specimens in two women patients, aged 25 and 30 years old, are
described. In the first case the tumor was small (0,5 cm) and
did not penetrate the wall of the appendix. In the second case
the tumor infiltrated diffusely 2 cm of the length of the wall
of the appendix as well as the mesoappendix. In this case the
appendectomy was followed by right hemicolectomy. Although the
tubular type of carcinoid and the goblet cell type have been classified
together as "adenocarcinoids" by some authors, the distinction
between the two is necessary because of their different prognosis.
Key words: Tubular carcinoid, appendix, adenocarcinoid.
