Lubarsch in 1888 first described the histology of carcinoid tumors (1) and the term carcinoid was proposed in 1907 by Oberndorfer (2) when described a submucosal tumor of the small intestine. Since then, carcinoid has been reported to develop in various organs, including gastrointestinal tract, liver, lung, breast, gall bladder, skin, trachea, parotid gland, and thymus (3). It is well known that sometimes carcinoid tumor is sometimes associated with other tumors. Approximately 15% of carcinoid tumors of the small intestine are associated with non-carcinoid neoplasms, most frequently adenocarcinomas of the gastrointestinal tract (4). The concurrent occurrence of carcinoid and other tumors in various organs is extremely rare. Two morphological patterns for such a combination have been described: one showing an admixture of the two components (composite tumor), and the other showing independent tumors withPrimary combined carcinoid and adenocarcinoma of the ileum associated with transitional carcinoma of the bladder.
