title: [Diffuse alveolar pertussis with major hyperleukocytosis with "pseudocentrocytic" contingent].
abstract: A 21 month-old unvaccinated boy was admitted for an acute respiratory distress episode associated with major leukocytosis (maximum = 146 G/l). Transient heart failure and pneumomediastinum occurred but the outcome was favourable. Coughing attacks then occurred and the diagnosis of pertussis was serologically confirmed. This case report is reminiscent of the possible severity of pertussis pneumoniae, the mechanisms of haematologic abnormalities, and stresses to the benefit of pertussis vaccination.
