A 27-year-old Bangladeshi complained of fever (39.2°C) and tenderness of the neck. He was admitted to our hospital. A fiberoptic laryngoscopy revealed oedema of the right side of the epiglottis. A CT scan showed a swelling of the bilateral parotid glands, submandibular glands and the right side of the epiglottis, and the neck and anterior thoracic wall showed phlegmonous inflammation (figure 1). Laboratory tests showed a leucocyte count of 7.2×109/l (neutrophils 59.1%, lymphocytes 30.4% and monocytes 6.3%), serum amylase of 1250 IU/l and C reactive protein of 1.44 mg/dl. He had not been vaccinated against mumps and had no history of mumps infection. The mumps titre was positive for IgM. The swelling gradually resolved within 3 days and the patient improved without complications by symptomatic therapy.
In Japan, routine mumps vaccination was discontinued in 1933. In previous reports, cases with mumps-related laryngeal oedema were only of adult Japanese because of the high incidence of mumps in Japan.1 Only a few countries in Southeast Asia (9%) and Africa (4%) use mumps vaccines in their national schedules.2 In these areas, there is the possibility of mumps-related laryngeal oedema as in the present case of a Bangladeshi. On the other hand, the UK, the USA, Canada and Ireland have recently had large outbreaks of mumps in young adults in spite of the high use of mumps vaccines (>94%).2 Laryngeal oedema may accompany mumps infection even in non-Japanese people. Therefore, it is necessary to keep the possibility of laryngeal oedema in mind when clinical doctors (including family doctors) encounter patients with mumps.
Complications by mumps tend to be more severe in adults than in children.
It is possible to follow laryngeal oedema with mumps infection in the large outbreaks.
