Goblet cell carcinoid of the appendix. An ultrastructural and histochemical study.
In a patient with a goblet cell carcinoid tumor of the appendix, light and electron microscopical studies demonstrated mucinous material and enterochromaffin granules within the same cell. Transitions between cells containing primarily mucin and cells containing numerous argentaffin granules were observed. Fluorescence studies demonstrated that the tumor cells contain biogenic amines.
