TWO CASES OF RECTAL CARCINOID

Abstract

We had two cases of the rectal carcinoid. Case 1 was the nonreactive carcinoid that neither argyrophil nor argentaffin reaction was positive. Case 2 was positive in both argyrophil and argentaffin reactions, but the main reaction was argentaffin. Cases positive for both argyrophil and argentaffin reactions were very rare, there are only five cases reported in Japan, including our own case.
