A 42-year-old woman with bronchial asthma since childhood was admitted
to hospital because of severe dyspnoea. Emergency bronchoscopic intub
ation had to be performed for Life-threatening inspiratory and expirat
ory strider. This demonstrated that the larynx was covered by a dirty-
grey membrane and the vocal-cord gap was narrowed to a mere slit. As l
aryngeal diphtheria was suspected 2000 IU/kg diphtheria antitoxin was
administered together with 1 mega U penicillin G four times daily intr
avenously. On the same day, Corynebacterium ulcerans, a very rare caus
e of diphtheria, was isolated from a coughed-up piece of the membrane.
Toxic, massive swelling of the lymphnodes and soft tissues of the nec
k necessitated maintenance of an open upper airway by intubation and (
later) tracheostomy for 41 days. A week later the patient was discharg
ed without any permanent defect.
