Tumors of the appendix are very rare neoplasms to detect. These neoplasms represent about 1% of the samples entering a surgical pathology laboratory. Current classifications distinguish neoplasia of the appendix in epithelial tumors, mesenchymal tumors and lymphomas. Epithelial tumors include neuroendocrine carcinoma and mucinous adenocarcinoma, this last type being the most common form of neoplasm of the appendix. In the present article two cases of appendicular mucinous adenocarcinoma are reported in a 85 year-old man and in a 49 year-old man, with similar clinical presentation.
