Duplication of the appendix mimicking adenocarcinoma of the colon
M. K. Bluett, S. A. Halter, K. E. Salhany and J. P. O'Leary
Duplication of the appendix is a rare anomaly that has been reported fewer
than 60 times. Three anatomic types of appendiceal duplications have been
described--each the result of a different embryologic occurrence. A unique
case of appendiceal duplication is presented, in which the duplication
caused a constricting lesion of the colon and mimicked carcinoma. The
anomalous appendix in this patient was not compatible with any of the
previously described types of appendiceal duplications.
