Abstract

Dalia M Badary and Mohamed Y Farrag

Background: Duplications of the gastrointestinal tract are many and variable, the most common sites being in the esophagus and ileum. The colon is infrequently involved. Even less frequent is malignant change in these anomalies. This paper reports a case of Primary transitional cell carcinoma (TCC) arising in a duplicated colon. Transitional cell carcinoma (TCC) arising in a duplicated colon is rare. We report a case of 61 years old male presented by epigastric swelling. Computarized tomography (CT) revealed the presence of cystic mass related to transverse colon. At surgery a firm perforated cystic mass with mural component connected to transverse colon was noted.

Methods: The mass was completely excised and gross examination revealed rounded cystic mass measuring 15x15 x3 cm in diameter attached to colon. Microscopic evaluation and immunohistochemistry study were performed.

Results: The mass was diagnosed as high grade TCC developed in duplicated colon and infiltrate the attached colonic wall.

Conclusion: To our knowledge, this is the first reported case of “pure” TCC arising in a duplication of the colon.
