RECURRENT CARCINOID TUMOR OF THE COLON.

Abstract

Carcinoid tumors are among the most unusual tumors occurring in man. This lesion was probably first described by Lubarsch in 1888 1 and was named and differentiated from carcinoma in 1907 by Oberndorfer. 2 These tumors arise from the chromaffin of the intestine which were first described in 1897 by Nicholas Kultschitzky. 3 Masson 4 demonstrated cytoplasmic granules in these which are capable of reducing silver compounds, hence the names argentaffine cells and argentaffine tumors. During the ensuing years there have been many reports in the literature of these tumors occurring in various parts of the intestinal tract. In the past decade they have been found occasionally to be associated with a bizarre symptom complex which has been named the syndrome or functioning carcinoid tumor. This discovery by Biorck et al 5 and Thorson et al 6 has added greatly to the interest and importance of these
