Carcinoid tumour of the larynx. A report of two cases.

Two cases of carcinoid tumours of the larynx are described. One was histologically a typical carcinoid whilst the other showed cellular atypia, numerous mitoses and invasion of the surrounding tissues. Both were argyrophilic but not argentaffin positive whilst electron microscopy demonstrated the presence of neurosecretory granules and amyloid. The previous literature on these rare tumours of the larynx is reviewed.
