  • SummaryA series of 12 carcinoid tumours of the appendix were examined with regard to S-100 protein immunoreactivity. All tumours were both argentaffin and argyrophil, and displayed immunoreactivity after application of a monoclonal antibody against serotonin. The S-100 protein immunoreactivity appeared in 11 of the 12 tumours, preferably in cells presumably of Schwann cell origin with long slender processes localized at the periphery of the carcinoid tumour buds. Immunoreactive cells with… CONTINUE READING
