چکیده
Tumors containing both mucinous and endocrine cells (adenoendocrine tumors) can be seen in the gastrointestinal system (1). Adenoendocrine carcinomas – histologically classified first by Lewin (2) in 1987 and later by Fenoglio-Preiser (3) in 1999 are located in a wide spectrum between collision and composite tumors and are often difficult to distinguish. Composite tumors are thought to arise through a multidirectional differentiation of a single neoplasm. Collision tumors are believed to result from biclonal transformation of two separate but adjacent neoplasms.
